[PHP] simpleXML - can't add children - why? - stuck
Hello all, I'm struggling here, but no joy so far. Having this XML file that I'm loading using simplexml_load_file(): http://pastebin.com/JiW3LxWM I need to add some domain:create children nodes after line 8. What do I need to add? This: http://pastebin.com/mT27g3ZN In order to do so, I have used the following php snipped: http://pastebin.com/a1gG8tXx I'm getting this warning and, after it, a fatal error: Warning: SimpleXMLElement::addChild() [simplexmlelement.addchild]: Cannot add child. Parent is not a permanent member of the XML tree. (line number 1 of last paste bin) Fatal error: Call to a member function addChild() on a non-object (line number 2 of last paste bin) Note that: The constant used is correct. The php version is higher then 5.1. On the same command, later on this code, I was able to create child nodes with no issues. I'm far (veery far) from being a guru, so please, what can I do to debug this, and find out what's going on?

[PHP] Migration Scheme - from one mysql DB to another mysql DB
Hello all, If possible, I would like to ask and have your help about the methods and procedures that should exist to accomplish the following task: I need to grab some data from one mySQL database with some specific table and field names, to another mySQL database with specific table and field names. The destination database tables are empty. What is a common procedure to do on those cases? Is there any? Several? What are the most common? If I need to be more specific in order to benefit from your help, please, let me know.

RE: [PHP] Migration Scheme - from one mysql DB to another mysql DB
I'd like to know - what type of hosting and OS the 2 databases are running. - if they're (staying) on the same machine, and if not: whats the available bandwith (updown, lowpeak) between the machines? any cost to that bandwith? - if you have admin rights on both databases. - how often you need to do this and for how much data (in Mb) Thank you all for your replies. I will leave you with more details, but, I believe the single query approach with two PDO (or mysqli) connections should be quite well. Both DB are on the same server, Linux based one, but different dsn should apply. The bandwith cost will not be an issue, because we are talking about 15MB of data, or something similar. I don't have admin rights but I can try to have them if I must to. I believe this will be a single time, or, one in a long time run but, we can never predict. The destination table also has some random data filled fields that I need to generate and introduce with the old data on this new database. Wondering if mySQL Migration Toolkit can do the job?

[PHP] headers help
Hello all, I must confess I know the very basics on this language and have even less knowledge about http headers. I wish you could help me out on this: I have a form that sends html e-mails and an optional file as attachment. The issue is that, if the file is NOT send, the e-mail receives two times the same content, one that gets read by the mail clients as HTML properly, and, a literal print of my $message string variable that contains: html head /head boby tableMy form contents/table /body /html I believe that the reason for this lies on the $header options, probably on line number 8 ? Here is the, what I believe, is the relevant code: http://pastebin.com/5ywdK0UU What should I do, to avoid this extra html code on the e-mail messages ? Thanks in advance, Márcio
[PHP] RE: headers help
I've had a quick look and this: http://pastebin.com/RswEBPLd may work; if not though you want to view the source of an email from anywhere which displays correctly; and the source of one from your application - then compare to get the fix :) Regards! Thanks Nathan, I will give it a try. Mime headers is what I should look for, ok. :) I found weird having more than 1 content-type defined, and more than one decoding method defined as well. I will do my part and try the code you give, try to understand the changes, do some testing, and now, search MIME Headers.

Ahhrrggg!!! Regards, Márcio Hello once again, I have take my time to think on this for a while. And I end up on the W3C recommendations about URIs: In a phrase: Keep it semantic, lifetime, and short. Several questions arise at this moment: I was having a url like this: http://www.mysite.com/c_mycontroller/method/1/3/4/54 Where the numbers where Id's of categories or products. Well... this could be as far as we can get from the W3C recommendations. :s So, let's say I short those urls to names, and I remove/hide(?) from the URL the controller and method information's. We could end up on something like this: http://www.mysite.com/categoryname/subcategoryname/subsubcategoryname/productname/ It's more semantic. But what if we have, 4 subcategories for example? This could get quite long. A possible solution to this, is to have something like this: http://www.mysite.com/categoryname/subcategoryname/productname In a way that we always get no more than 3 URI segments. So, if the user navigates to a sub sub sub sub level on the hierarchy, the address could be: http://www.mysite.com/categoryname/subsubsubsubcategoryname/productname 1) What are your thoughts on this? Should I follow this track on your opinions? 2) In order to be semantic, I intend to pass through the URI segments, NOT the Category id's but the Category names. This will bring two issues (at least): 2.1) - I need to query the database, not by ID but by Name. (I'm not sure if they always be unique, I'm not sure if I will have a performance issue). As a note: This is a VERY little website. Nothing too fancy. 2.2) I will grab the categories name from the database, and build the URL with those names, however, some category names will have INVALID chars, like á, ç, spaces... etc... What would be the best way of doing this? Having a new column on the database categories table with a slug field? Or, grab the category name, and prepare that name to be url friendy using a function for that? If it's possible to answer, where on a MVC structure would this function be?

RE: [PHP] dynamic menu with show hide capabilities - understanding possible workflow
That sounds about right yeah. You could also get a little bit clever and only retrieve the rows from your db that will go to make the array elements you'll need. It doesn't make sense to retrieve a full product list each time someone visits the page, Ok. so you only need to retrieve those that the user is interested in, which is shown by what they click on. The relation between click and the display of the corresponded array child elements, without using js, is the hardest to understand: The user will click on a link / the URL will change / the new page will be loaded to the user / the information displayed on that page should be related with the element clicked on the first step. So, the next page, should know what we have clicked before, in order to display the information accordingly. One of the ways that this can be done, is by passing params over the URL. The URL param will tell us what element have we clicked, so it should be based on URL. Once we have that, we need to ask: as that value passed on the url a correspondent array element that contains children? If so, display them. (I realize my incapacity of talking technically, by referring to pages and other odd entities. I'm sorry for that). Does the above makes any sense?

[PHP] dynamic menu with show hide capabilities - understanding possible workflow
Hello all, I'm on my way to build my first dynamic menu using php. However, each time I say this, people start jumping at me crying out loud: Jquery . I don't need js for this. Really. (At least, this is what I believe). So I was wondering if It's possible to accomplish it, by using css and php only. If so, I'm wondering if something like this it's a good way for doing this: 1) Generate a multidimensional array from database table containing categories and subcategories. 2) Create a css file with two classes one that shows, another that hides. 3) Grab that array and: 3.1) print it recursively (no idea how to accomplish this) 3.2) print it with some sort of class=showThis inside the generated html element. 3.3) make a conditional somewhere (I really don't know where, and this may be related with the recursion doubt), in order to display the children elements, only when we click the parent element.

RE: [PHP] dynamic menu with show hide capabilities - understanding possible workflow
Thank you all. Ok. Please stay with me, cause I still have some doubts. Not only do I need to display the subitems on click but also, when the user clicks on one menu item, I need to change the URI as well. Why? Because, each time the user clicks on a menu item (whateaver that item as childs or not), I want to display a list of products related to the clicked item. So, I was trying to avoid js, because, I don’t know that much about js. However, I’d like to do it properly, so, the only way I was allowing the use of js, was by do not disabling the back button functionality and by allowing a add to favorites option as well, allowing the URI changing… O.o Anyway, let’s face it: Js is my only option, could this be a nice workflow, for an unobtrusive solution? 1) Generate the multidimensional array from query. 2) Generate the ul / li menu (echo + foreach) displaying all child elements as well. 3) Apply the anchor to the list items. 4) Apply some js to that ul / li that: 4.1) will be responsible for show/hide elements. 4.2) Will be responsible to show/hide elements only when some DOM node(?) as children. 4.3) Change the URI on click, so that some information can be showed based on uri segment. Can I have your help to fill the blanks here, or, if there are to many, just an orientation reference, in order to get started… Thanks a lot once again, Márcio From: Ashley Sheridan [mailto:a...@ashleysheridan.co.uk] Sent: segunda-feira, 26 de Outubro de 2009 14:38 To: MEM Cc: php-general@lists.php.net Subject: Re: [PHP] dynamic menu with show hide capabilities - understanding possible workflow On Mon, 2009-10-26 at 13:28 +, MEM wrote: Hello all, I'm on my way to build my first dynamic menu using php.

Pure CSS-only menus are still unavailable because of IE, so using some Javascript is your only option really. Is there a particular reason you are shying away from Javascript in this case? There are ways you can construct drop-down menus in a way that if Javascript is unavailable, then they fall back to becoming a bog-standard navigation bar. Also, before anyone mentions them, select lists are not the same thing as a drop-down menu, and navigating to different parts of a document upon changing the selected option is actually breaking their default behavior, and can become confusing to people who expect them to work as select lists.

RE: [PHP] dynamic menu with show hide capabilities - understanding possible workflow
Thanks a lot for your replies. Let's see if I understand, if not, please, let me know, I'm not that proficient in English. Second try, in order to accomplish this, I have to: 1) Generate the multidimensional array from query. 2) Generate the ul / li menu (echo + foreach) displaying all child elements as well. 3) Apply the anchor to the list items. 3.1) Each anchor on this list should point to a new URL (I don't care if the page refreshes on this case). 4) Print all this on a nice way to the browser. (unobtrusive) 5) Apply js to: 5.1) HIDE the elements that need to be hidden. 5.2) SHOW what needs to be displayed. I don't want to have any onHover effect. The submenus will not appear on a onhover effect. They should appear when the user either clicks on a parent menu item, or navigates to a specific URL. Should this make me change this workflow somehow? Please have patience... :s Thanks again, Márcio -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

RE: [PHP] Newbie: Array of objects iteration
@LinuxManMikeC and all @All
Thanks. I was more or less aware of that possibility, however, please let me
share the big picture will you guys:
The main point is to access the properties name as well as values, of that
object, and put them on a xls file.
Instead of using mysql_num_rows, and mysql_num_files, and split and use a
bunch of loops I thought:
Maybe fetching as an object may help me doing this far better.
However, I'm having a hard time figuring out how to make the switch.
To be honest, I don't really know if iterate is the buzz word here, I
would like to understand a little bit more the following:
We have in our hands an Object returned by a Fetch_All w/ fetch_obj option
applied to it, that object, when I do var_dump, reveals himself as in
object, containing an array and, each key of that array corresponds the
column names of our table or tables we have previously fetched.
However, since we are working with an object, should we think differently
than if we were working with an array? If so, it is, in the fact, iteration,
the best option we have to put all properties and values into a xls file? Or
there are far better options for that?
@Lester
Yes, actually, I was having only one record on the database, but I believe
that is far to less. Since I was not been able to see if I was getting one
object, or several objects. That make me think of that. Thanks :) And
because of that, I was able (I hope) to properly understand Fernando
example:
@Fernando
foreach ( $records as $record ) {
foreach( $record as $column=$value ) {
echo $column is $value\n;
}
}
So the first foreach will iterate over each object of stdClass that
corresponds to each record of mysql data fetched, then, for each of them,
take the associative array key and the corresponding value...
Correct? :DDD
However, is this the right track to archive the goal stated above, or, they
are far better ways for doing so?
Regards,
Márcio

You've got the columns names in each record, not in the global
recorset.
print_r($record); often helps - you can see what is actually returned
and check that you have names rather than numbers for the fields ;)
print_r($records); becomes a little large if you have a lot of results
so use with care :)

RE: [PHP] Newbie: Array of objects iteration
Correct about my example, although I'm not sure if you get each record as
an array or as an object. Anyway, you can iterate both.
And if you want to get the column names, I suppose you could use
array_keys() on the first record if you receive an array, or maybe
get_object_vars() if it's an objecs (note that with this you get an array
with keys and values).
I've found PDOStatement-getColumnMeta(). There's a big fat warning saying
this is experimental, but you could take a look in case you need more data
on the columns.
Hope it helps.
Right now, I have something like this:
foreach ($objRecord as $record)
{
//we will have a new line.
$xls_file .=\n;
foreach ($record as $column=$value)
{
$xls_file .= $value.\t;
}
}
The only thing I need now, is to put on top, the column names, and I have
myself a xls file. YUpii!!
I just need the column names... I will take a look on those functions you
have mentioned.
Thanks a lot, :)

No success. :s

Before your e-mail, I've considering the use of this:
if (!is_numeric($telefone))

$erros['numberofsomething'] = 'Error - only numbers please.';

I meant this of course:

RE: [PHP] FILTER_VALIDATE_INT - newbie question
Well, it was only a guess, but if you look at the integer limit on 32-bit systems, you'll see that the upper limit for numbers is 2147483647 (or 2^31-1) which would explain maybe your upper limit problem. Also, I think you're getting confused over the zero with exactly what you are asking PHP to do. filter_var() returns true if the filter matches. If the 0 match is returned as a false, then filter_var() will return false. You're then inverting that with a !, all of which is inside an if() statement. Essentially this would mean that if the filter returns false then the instructions inside of the if statement are carried out. I always thought that that was a limit of the number of digits an integer value could have, and not the actually int value... I guess I was wrong. :s You are right, I've tested with: 2147483647 it worked. I've tested with: 2147483648 It displays the error. you're getting confused over the zero with exactly what you are asking PHP to do Absolutely... :( If I put 0 filter_var() will return false. If I put 0342352 filter_var() will also return false. Could we say that: if it is indeed the fact, that filter_var() returns false when it finds a 0 at the beginning of a given number... then the instructions inside of the if statement are carried out. And here may be the reason for displaying the error message when we have the 0 leading a number. And my point was exactly here If the 0 match is returned as a false Why should filter_var() do something like this? Should the filter_var() interpretate 0 as a number without boolean semantic value? Please be patient... Regards, Márcio -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] FILTER_VALIDATE_INT - newbie question
Well, at a guess, if a number is 0, PHP see's that as equivalent to a
false.
In this case, shouldn't php ignore the 0 as false?
Also, numbers over 10 digits may be going over the limit for
your
PHP install, assuming PHP actually attempts to convert the string to a
real integer for the purpose of the filter.
This happens with two different php configurations... Is it common to have this
kind of limit on php configuration?
Is this something that I need to be aware of?
For things this simple,
THIS IS NOT SIMPLE !!! :) Newbie blood is in there! :p
Kidding. ;)
I've always tended to go with something like
this:
if(!preg_match('^[0-9 \+]$', $telefone))
{
$erros['telefone'] = 'Invalid Teléfono - Only Numbers Allowed.';
}
Which will check for all common types of phone numbers, including those
where the user has put spaces in to separate groups of digits, and
those
that contain the + for country codes.
I will absolutely considerer the use of your regex. Thanks a lot.
Before your e-mail, I've considering the use of this:
if (!is_numeric($telefone))
{
$erros['numberofsomething'] = 'Error - only numbers please.';
}
In the case we need to validate other ints, that are not phones for example,
only an unlimited range of ints,
and we want to store that values on a database, should we have special
considerations regarding the use of is_numeric ?
Thanks a lot,

RE: [PHP] FILTER_VALIDATE_INT - newbie question
Thank you all for your replies. The issue was solved for a better fitting solution on this case, that was by using a regex expression. I've not tested the difference between using == or ===. I was using ! But, the main question that is not clear on my newbie head is, why how why couldn't this 0 be interpreted, neither as octal, or false, or whatever it may be, but as just a humble numeric value of 0. At least on the cases where FILTER_VALIDADE_INT is there. Anyway, I cannot dig in into this because I'm actually unable to offer some solutions. So, as stated, the issue was solved, by using a regex, so all good here. ;) Thanks once again, Márcio -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Regards, The newbie on a Humpty Dumpty wall, Márcio Firstly, ?= is a bad idea, as it's not very portable and relies on short tags being on, which causes all sorts of problems should you ever need PHP to output XML. The only reason I can see that the div will always appear is a logic error. Are you sure that the $erros['anexo'] variable is not set at some point and not just set to an empty string? An empty string is very different from an unset variable. Try using var_dump($erros['anexo']); in your code somewhere to see if the it is actually an empty string instead.

RE: [PHP] Self-Process php forms or not?
Thanks a lot. To all.
For the moment, I'm with the redirect solution that others have pointed.
But after seen tedd example and watch Manuel videos, I'm starting to
understand how the hidden field solution work as well. Well... I'm
*starting* to understand I've not fully understand it yet, despite all your
great examples.
Because the structure of the code with hidden fields, seems quite different
from the structure I have right now and I'm unable to make the switch.
Here is the actual structure:
if (isset($_POST['submit']))
{
//declare variables
$var = $_POST['var']; etc...
//validate
//process the form
(send e-mail or save to database etc...)
//redirect to success page.
}
else
{
Echo Sorry, couldn't process the form;
}
html form
I suppose that the echo message telling we couldn't process the form does
not appear when the form first loads, because the server side script is not
requested on load, it is requested when the form submits to the php code
presented on that same page (self). Tom Worster, is this precise?
In the future, I will print tedd example, and Manuel scheme, and try to
change the code above to accommodate hidden fields, because I still prefer
having only one file.
Thank you all once again,

RE: [PHP] Self-Process php forms or not?
i don't think so. if the user requests the page a_form.php then the server will normally execute the a_form.php script regardless whether the form was submitted or not. to display a blank form, the user probably requests a_form.php with the GET method and probably without any GET parameters. the script will run but $_POST['submit'] is not set. so the script you show above will echo Sorry, couldn't process the form. that will likely confuse the user. Ok... but please have a look here, I've uploaded and tested that code, and I can assure you that the message doesn't appear when the form first load: http://pastebin.com/m21078fe3 Note: if you use: copy to clipboard option the numbers will gone.

But as an additional information, I'm marking all this e-mails for latter reference and study. as i said before, a script will execute regardless. but this new script fragment does nothing except initialize $erros if $_POST['submit'] is not set (e.g. if the user requests the page without POSTing the form). i don't see a problem. this script also has the three cases i described clearly separated. now, what was your question? None. I've not properly see the structure that I was in, and according to that mistake, I've taking wrong conclusions. But thanks for pointing it out.

RE: [PHP] Self-Process php forms or not?
I want to apologize to you all. I have mentioned two things on the same basket, but it was not appropriate. Since a confirmation page is not the same thing as a success page. Let's forget about the confirmation page, since it's not required. I'm now understanding that even if the form is submitted to self, we can still use a redirect to a success_message_page.php. However, we must do this redirect, AFTER the form has submitted to himself. It's the only thing that we have to pay attention here, correct? Since we are not dealing with a confirmation page, or a multi-step form, the hidden field isn't necessary. It's this correct assumptions?

You say you don't use hidden fields because they can be modified too easily, yet you say you check for the submit button? Which out of the two do you do, as last time I checked, modifying one form field is as easy as changing any other! I completely agree with you. changing submit text is as easy as changing hidden fields, but its less likely for a user to modify a submit button as compared to a hidden field. moreover it just reduces my typing load. (This is just my practice) Also worth noting, you can only successfully check for the name=submit value if there is only one submit button in your form, as that is then the default (and only) submit that the form can use, so it uses that. If you have more than one submit button (and this includes image input elements) then using the keyboard will use the first submit field it finds I believe. Cant agree with you on this though. as far as i know using name= (names of the two buttons may/may not be unique) is the only way to track form submission for forms with multiple submit buttons.

You can set it up any number of ways. There is no absolute need for a redirect. Everything can be done in one form, or not -- your choice. Cheers, tedd Yes.

MEM:
Here's what I do -- it's pretty simple.
I use a hidden input variable I call step and monitor it as the
user clicks whatever form submit they are on -- it works like so:
$step = isset($_POST['step']) ? $_POST['step'] : 0;
switch ($step)
{
case 0: // present the first form to the user
// collect data
// you can enhance the user experience by using javascript here.
// input type=hidden name=step value=1
break;
case 1: // present second form to the user
// clean data
// if data OK then record data in db input type=hidden name=step
value=2
// if data not OK then send user back input type=hidden name=step
value=0
break;
case 2: //present the third form to the user
// success, or confirmation, or thank you page
break;
}
Now, to make things easier for the user, be sure to set session
variables for all the data collected in the first form so that IF you
send the user back to the first form, the user doesn't have to
reenter everything.
i do pretty much the same thing. each form in my html template files
has a
form name tucked away in a hidden input element. the only difference
from
your method is that the names are unique across the application.

[PHP] stdClass - A newbie question
Hello everybody,
In this class sketch:
?php
class Pagination {
...
public static function Pagination ($total_records, $limit, $page)
{
$total_pages = ceil($total_records / $limit);
$page = max($page, 1);
$page = min($page, $total_pages);
$offset = ($page -1) * $limit;
$pagi_obj= new stdClass;
$pagi_obj-total_pages = $total_pages;
$pagi_obj-offset = $offset;
$pagi_obj-limit = $limit;
$pagi_obj-page;
return $pagi_obj;
}
}
Why do the author used a stdClass ?
What are the advantages of using a stdClass?
Since we are already inside a class, why do we need to create a new object
from another class, inside this one?
Why do we keep the values passed as params on method Pagination inside this
stdClass object, and not inside Pagination own properties for example?
Any help clarifying this, knowing that I'm a newbie,
Regards,

RE: [PHP] stdClass - A newbie question
By the way, there are many reasons for creating objects inside of other
objects. This should not be considered an exception. I don't know where
this code belongs to, so I can't clear out if it is good or bad OOP
style.
I do not intend to public judge the author, but the original article is here,
just for proper credit:
http://www.phpro.org/tutorials/Pagination-with-PHP-and-PDO.html
Just think about everything in classes and objects - even return values
or other things, that you would normally consider as volatile. (eg. a
network connection)
It would be a nice exercise to practice. :) Thanks for the tip.
And thanks a lot for the reply, I'm almost there... one last newbie question:
When we have something like this:
Class Pagination
{
Public static function Pagination ($limit, $total_records, $page)
{
$pagi_obj= new stdClass;
$pagi_obj-total_pages = $total_pages;
$pagi_obj-offset = $offset;
$pagi_obj-limit = $limit;
$pagi_obj-page = $page;
return $pagi_obj;
...
How can we, later, have something like this, for example:
$pagination_obj=Pagination::Pagination(some params)
$pagination_obj-offset;
?
I mean:
When we instantiate the class by doing:
$pagination_obj=Pagination::Pagination(some params)
We will have an object ($pagi_obj) returned where the properties of that object
will be *referring* to the values passed on the method argument, right?
How does those $pagi_obj properties, can then be accessible by doing
$pagination_obj-offset; ? I mean, they are attributes of our stdClass object
(aka pagi_obj), and they are not attributes of our Pagination class, or are
they?
Thanks in advance,

[PHP] Newbie: Composition by Association - Pagination Class general question.
Hello, I have a Animals DAO class that I'd like to apply a pagination class to it. Between this two classes, there will be a composition relation (more precisely, an association one). My question is: Is a Pagination that has a Animal. OR Is a Animal that has a pagination? Should we create on Class Pagination a property named $_animal OR, should we create on class Animal a property named $_pagination? I'm inclined to accept the second one, since, if I put the property $_animal on my classe Pagination, I will end up, on the Pagination Class, with so many properties as pagination objects... :s Any help please?

RE: [PHP] Newbie: Composition by Association - Pagination Class general question.
Pagination is the generically applicable class - it should know nothing about what specifically it's paginating. Ok... but I need to grab values of my DAO classes, I mean, even if we paginate images on a directory or records on a database table, the pagination should have a $limit, and a offset, a way to count how many item there are to work with... So it must be related with the DAO (or other thing) on some way, so that I can grab those values and play with them on the pagination class... Should I use a Decorator Pattern to make this relation between the pagination and the DAO ?

RE: [PHP] Newbie: Composition by Association - Pagination Class general question.
I don't know how your other classes are arranged, myPDO.class.php - Singleton. Makes the connection to the database possible. generalDAO.class.php - Abstract DAO Class, grabs the myPDO instance and could have other methods on the future that are shared for all the DAO classes. AnimalsDAO.class.php - DAO class with insertAnimal(); deleteAnimal(); updateAnimal(); countAnimal(); selectSpecificAnimam() methods... The same goes for the VetDAO.class.php. but personally I'd build pagination into a class that provides raw data access, then inherit that for specific types of data like animals. Efficient pagination is too tightly coupled to the data source to be separate. According to the above, does this suggestion of yours still apply? If so, what is the buzzword that I should look at so that inherit that for specific types of data like animals could be possible? What/where should I look/search to accomplish your suggestion?

RE: [PHP] Newbie: Composition by Association - Pagination Class general question.
I would say your pagination logic belongs in myPDO.class.php. Where I have this functionality it's as simple as two arguments to the method that gets data, $page and $perpage. Setting both to false would retrieve all rows. Interesting but, still no clue, on this side, about how to accomplish that. I'm still a newbie. Can you throw some key words so that I can google them and look for a way to implement that?

RE: [PHP] Re: Newbie: Composition by Association - Pagination Class general question.
As for (1) even in my pre-OO days I was used to using a single generic DAO for all database access. The only time that more than one DAO existed was for a different DBMS engine. This is why I have one DAO class for MySQL, one for PostgreSQL and another for Oracle. If you are incapable of writing a single generic DAO then it just shows that you still have a lot to learn. For an idea on how this works take a look at http://www.tonymarston.net/php-mysql/databaseobjects.html I'm absolutly sure that I have a lot to learn. Really a lot. :-) I have post some days ago, a way for using a generic CRUD class and DAO, but I get no replys so I wrongly suppose that my question was a nonsense question, and that CRUD and DAO would be a nonsense. As for (2) it should be obvious that pagination is not an entity in its own right that has its own properties and methods, it is merely a function which can be performed on any entity within the system. Ok... It should also be obvious that the requirements of pagination cannot be satisfied in a single class as some of the processing has to be handled in the presentation (UI) layer while the remainder is handled in the data access layer. That's why I was thinking on using a Decorator Object on the Pagination Class (that will retrieve DAO values to operate). The presentation layer needs a means to submit a request for a particular page number as well as the page size (rows per page). These two values are sent to the DAO which then translates them into values for LIMIT and OFFSET. After the DAO has issued the sql SELECT statement it needs to return two values - the current page number and the last available page number. The presentation layer then needs a mechanism to display these two values. This is explained in http://www.tonymarston.net/php-mysql/pagination.html Thanks for explain the workflow! I will read. If you still don't see how this works then you can run my sample application at http://www.tonymarston.net/php-mysql/sample-application.html You can even download the code so that you can step through it with your debugger. I haven't learn how to use a debugger yet. And I'm sure it would help me a lot on understanding some data workflow...

Also, I also intend to use fetchObject method instead of fetchAssoc quite often, with also puts your tutorial far away from my capacities. Because of this, I'm trying to follow what I can get on the web, using PDO and general CRUD operations: BUT: Here: 1) http://oopgarden.richardknop.com/index/view/1 or Here: 2) http://phpro.org/tutorials/Easy-Access-With-PDO-CRUD.html when we have to create complex querys by using limits, order, etc... either they are inexistent possibilities (like on the link 2), or, like on link 1 they are so close to the equivalent sql sintax that I'm questioning the advantage of having a general DAO CRUD class at all (supposing that the only advantage is that we write less words on the code). Please advice, besides the fact that we never have to code any of the SQL SELECT, INSERT, UPDATE or DELETE statements for any table as they will be generated at runtime., is there any other advantage on using a general DAO class instead of one DAO class for each table? :( Regards, Márcio -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] Re: Newbie: Composition by Association - Pagination Class general question.
Why not? Why can't you replace a call to a mysqli function with a call to a PDO function? It's not just a simple replacement - I need to add bindparam, prepare, execute, placeholders and fetchObject. But I will give it a try... Also, I also intend to use fetchObject method instead of fetchAssoc quite often, Why? What's the benefit? The fetchAssoc method gives you an array of values, while the fetchObject method gives you a container for an array of values. You still still have to work with an array of values. FetchObject maps the field names from the database as object properties with the values stored in the database. Seems quite nice. Then, to access a specific column data I just needed to: $myhandler-my_database_column_name (it seems quite nice to me) :) Why don't you learn how to use the mysqli functions before you handle the switch to PDO? What do you have to lose? I already work with PDO so, no need to switch. :-) If you read my tutorial you should see that building a SELECT statement is nothing more than combining several small strings into a larger single string. String manipulation is simple in PHP. Using this technique I can create very complex SQL statements, so don't tell me that it can't be done. I was not talking about your tutorial. I was talking about those two links, mainly the first one where, unfortunately, the difference between the code and the sql sintax is that we don't have the word SELECT and WHERE. :s However, as a positive point, this class uses BindParam and ? placeholders. But I get your point, we can cut it into smaller strings. Because you have less code to maintain. If you look carefully you should see that the only difference between the DAO for TableA and the DAO for TableB is the table name and the table structure. If you could pass these as arguments into a generic DAO then you would not need a separate DAO for each table. Yes. But you still need, for each table, to fill one or several (depending on what mysql connection method we use) arrays with values. So that less code maybe isn't that much in a way where you *significantly* reduce your maintenance burden, if you take into consideration that we take the queries for each table, but a) we add arrays and b) use a less intuitive way to add/remove/delete values to the database. As an example I have give link 1, where the difference was more or less two or three words - and the way to use the arrays where far more complicated to understand then a simple Select Sintax - hence, not that relevant. OOP is about creating reusable code to reduce the maintenance burden, so if you insist that a separate DAO for each individual table is the way to go then you don't understand how to apply the principles of OOP correctly. I will never insist just because some silly reason comes to my mind. I will however not follow a method without knowing the reasons and be convinced of them. I'm not 100% convinced of the reducing benefits for the reasons a) and b) stated above, still, maybe I get more benefits the more I add methods to the DAOs. In the next few days I will try to, based on your code, create a general DAO class that deals with PDO. And post back my frustrations back here. :D Please have patience. :D Regards, Márcio -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] Doubts concerning a general Insert method
Ok... according to the above posts, I've started to create my generic CRUD class however, I'm wondering: Any of you have already used a DAO design pattern in conjunction with a CRUD generic class? Know that I'm trying to create a generic CRUD class on a DAO Design pattern, it seems that it makes no sense at all. Is there an advantage on doing this? My thought: On a insert to database scenario for example: Without the CRUD generic class: to do an insert, we instantiate a DAO class and then call the insert method. Nothing more. Done. With the CRUD generic class: maybe we will have less code on the DAO site but, at the end, to insert a record, we still need to instantiate a DAO and call a insert method SO... I see not big advantage on using both... Can I have your advice on this please? Thanks, Márcio -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Doubts concerning a general Insert method
Hello, I'm trying to understand a general CRUD class that I've seen here:
http://www.phpro.org/classes/PDO-CRUD.html
I'm learning PHP and I have some doubts on this method to generally insert
data into DB. The class name is crud and here is the method:
public function dbInsert($table, $values) {
$this-conn();
$fieldnames = array_keys($values[0]);
$size = sizeof($fieldnames);
$i=1;
//construction of the prepared statment
$sql = INSERT INTO $table;
$fields = '( ' . implode(' ,', $fieldnames) . ' )';
$bound = '(:' . implode(', :', $fieldnames) . ' )';
$sql .= $fields.' VALUES '.$bound;
//prepares statement e saves it on variable $stmt
$stmt = $this-db-prepare($sql);
foreach($values as vals)
{
$stmt-execute($vals);
}
}
To place values on the DB we do:
$crud = new crud();
$values = array
(
array('animal_name'='bruce', 'animal_type'='dingo'),
array('animal_name'='bruce', 'animal_type'='kangaroo'),
);
$crud-dbInsert('animals', $values);
The doubts:
1) Names convention question:
Isn't more correct to call $columname, instead of $fieldname ?
2) Why do we have this?
$i=1
3) Here:
$fieldnames = array_keys($values[0]);
We are keeping on variable $fieldnames, the key value of the $values array,
when this array is on the position 0 ? And what is *actually* the value
returned, considering our array?
$values = array
(
array('animal_name'='bruce', 'animal_type'='dingo'),
array('animal_name'='bruce', 'animal_type'='kangaroo'),
);
4) Here:
foreach($values as $vals)
{
$stmt-execute($vals);
}
We are telling that, for each (line/element/index ???) of $values array, the
actual value will be given(?) to vals, and the pointer goes to the next
(line/element/index)... ?
We then execute the prepared statement, but I don't get what are we passing
as a param? I mean, what kind of think does the execute PDO method expects
as a param?
Why $stmt-execute($vals); and not only $stmt-execute(); ?
Can I please have your help on clarifying those doubts?
Thanks a lot,
Márcio

RE: [PHP] Doubts concerning a general Insert method
$values[0] will give you the first element of $values, namely
array('animal_name'='bruce', 'animal_type'='dingo').
array_keys will return an array containing the keys from the
passed array, so in this case you'll get array('animal_name',
'animal_type').
So... since $value is an associate array of arrays, we will get, on the first
key, not an array with 0, 1, like array(0,1); but
array('animal_name','animal_type'), yes?
When we use the implode over this array, we get:
animal_name, animal_type that is the string that will pass to be prepare using
the PDO prepare().
After it's finished building $sql use var_dump to look at it. You'll
see that the values are specified as :animal_name and :animal_type.
The : indicates to PDO that these are replaceable values.
Yes. And normally, to fill those replaceable values, I was used to use
bindParam();
I like this bindParam method because we can then use PDO::PARAM_INT and
PDO::PARAM_STR to more accurately control the data type flow...
The foreach will go through the $values array and for each row it will
pass the data (e.g. array('animal_name'='bruce',
'animal_type'='dingo') for the first time round the loop) to the
execute function which will effectively replace those elements in the
SQL statement and execute it.
Ok, so:
Our $sql will be: INSERT INTO $table (animal_name, animal_type) VALUES
(:animal_name, :animal_type)
We then prepare this $sql by doing:
prepare($sql); and the value of this preparation will be kept on a variable
name $stmt.
Finally, on the foreach, we will grab each value of the $values array, and keep
him, on a variable called $vals,
The $vals will contain this on the first occurrence of the loop:
array('animal_name'='bruce', 'animal_type'='ding')
and then, the var $vals will have this on the second occurrence of the loop:
array('animal_name'='bruce', 'animal_type'='kanguro')
etc.,
At the end of each of these loops, we will process the execute (that will send
the statement to the database).
$stmt-execute(array('animal_name'='bruce', 'animal_type'='kanguro').
So this execute will do A LOT, it will take away the 'array(' part, will see
the keys of these arrays (e.g. animal_name and animal_type) compare them with
the placeholder names given on the prepare statement and, replace the
placeholder names with the values inside on each of this array keys.
Is this correct?

Márcio

RE: [PHP] Doubts concerning a general Insert method
Nice. :-) Thanks a lot Stuart for your time and explanations.
Now that I have understand, I will try to move on, and understand how can we
introduce bindParams on it:
For a recall, here is the original class:
public function dbInsert($table, $values) {
$this-conn();
$fieldnames = array_keys($values[0]);
$size = sizeof($fieldnames);
$i=1;
//construction of the prepared statment
$sql = INSERT INTO $table;
$fields = '( ' . implode(' ,', $fieldnames) . ' )';
$bound = '(:' . implode(', :', $fieldnames) . ' )';
$sql .= $fields.' VALUES '.$bound;
//prepares statement e saves it on variable $stmt
$stmt = $this-db-prepare($sql);
foreach($values as vals)
{
$stmt-execute($vals);
}
}
However I do have some questions that maybe someone more experimented then me
could easily solve:
1)
The bindParams should look similar to this:
$stmt-bindParam(':animal_name', $animals-getName(), PDO::PARAM_STR );
$stmt-bindParam(':animal_type', $animals-getType(), PDO::PARAM_STR );
So, instead of looping trough an array of values, I will to do it for objects,
something like:
foreach($animals-listaAnimals() as $row) ...
Can I have some words on this so that I can properly try to add bindParam on
this class method.
2)
I also need to have a way to add PDO::PARAM_STR if the values is a string or
PDO::PARAM_INT if the values is int, PDO::PARAM_BOOL etc...
Is there a way to control this? Using something like is_integer() and
is_string(), inside if statement perhaps? If so, what about the Boolean?
Thanks a lot,

However, when I do this, I notice that instead of giving me the column names

Can I replace this part:
$dbh = parent::__construct( $this-dsn , $this-user , $this-password );
$this-handle = $dbh;
return $this-handle;
By this: (?)
$this-handle = parent::__construct( $this-dsn , $this-user ,

And put a return on my getHandler method?

$queryh=$conn-prepare('SELECT id_cliente, nome_cliente FROM cliente');
$queryh-execute();
/*trys to access the method fetchObject of the PDOStatement generated by
the execute() PDO method, and save it on $row variable:*/
$row=$queryh-fetchObject();
/*now I'm trying to echo the results. The 'id_cliente' and 'nome_cliente'
are the column names of my database and, if I get it right, the
fectchObject() method should allow me to access those names as anonymous
properties. So: */
echo Id: .$row-id_cliente. - Nome: .$row-nome_cliente./ br;

Here is the issue that Im getting:
Im getting no values from the database upon echo request.

Question:
What is wrong with this code? :(
There is something definitely wrong with your code. But why did you forget
to use the debugging functions :
print_r()
and var_dump() for the results?
So, you'll get some idea beforehand of posting the problem here. I am
looking at the code in a hurry so I cant help you much right away.

would be greatly appreciated.
