[PHP] DAO/VO Pattern Help
Hello all, As I am trying to take my PHP code in a more enterprise direction with strict model/logic/view layers, I have been working with DAOs and the matching VOs. So I am running into a problem that I could really use some direction on: DAO/VO works great with single tables, but I tend to make my database work for its existance, and joins ar eeverywhere. What I don't understand is how to approach DAO/VO when table joins are involved. Can anyone think of some good resources?

[PHP] Re: mysql problems
Thank you both for your responces. Unfotuantely there is no form that instantiates this action. So the double submit (while a good idea), is not possible. As for some sample code, it is part of a rather complicated system that makes a number of changes but essentailly what is going on is this: 1. Grab all items that we need to do some shipping stuff to. 2. Foreach through the items, giving each item number to a function to assign it to a customer and create a mailling label. That simple! The interesting this is this - the duplicate record is inserted into the mailing labels queue. I can see it long before I grab the data for output to labels. Moreover, I can tell that the problem isn't in the original item select statement because the function (executed for each item) would have created different insert times in the database based on the now( ). More ideas? Thanks! Jed R. Brubaker [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Hi all - I could use a lead on a problem. I just don't know where to start.

It is the same query, same information, even the same time (there is a now() in the query - and it is identical). So the question is a simple one - is this a PHP problem or a MySQL problem?

[PHP] bizzare duplicate mail() call
Hello all - this problem is so wierd that I don't even know where to start. Hopefully you all can give me a couple leads. I have some reporting systems going on in various places on the server - mail() is called when a user does this or that. These scripts are farily simple, so I am next to certain is isn't the code - but every once in a while, more than one duplicate email will be sent. What is so strange is that it only occurs for these odd periods of time. For example, yesterday from 4pm to this morning at 7am, 2 copies would be sent. Last week for several days, 5 copies would be sent. The emails are frequent enough (every couple of minutes) that it is very easy to track, but I don't have a clue as to what would be the cause. Does anyone have any suggestions as to where to start looking? Thanks in advance! -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] mail problems - phpinfo information
I have been having all kinds of problems with the mail() function in PHP. I realize that there are problems inheritly, but I think I am still trying to track down the problem. My latest theory is that PHP isn't set up to work with the right mailing program. I know that our system is supposed to be using qmail that actually sits on a different server, but I found interesting information in phpinfo that is making me wonder if a local sendmail is handling the requests instead. Here are the things I am finding in phpinfo: sendmail_from no value no value sendmail_path /usr/sbin/sendmail -t -i /usr/sbin/sendmail -t -i SMTP localhost localhost smtp_port 25 25 Path to sendmail /usr/sbin/sendmail -t -i Enviornment MAIL /var/mail/kpratt (what does this one do?)

Re: [PHP] mail problems - phpinfo information
So as I am not an administrator, and all I have to go on is phpinfo (unless anyone has some suggestions), should I be seeing some trace of qmail in the phpinfo? That is why I posted. I apologize if I didn't make it clear. I have read all about mail, and even used the fantastic Lemos MIME problem correcting email class to try to tackle my problems from a different angle.

[PHP] database content searching
Hi all. I was wondering if any of you have experience with searching through a database for user provided search terms. I was hoping that maybe I could get some insight into how to better approach what I am doing. Are there any great articles or example classes that I could look at? Please let me know! As of right now, my architecture is to have a primary class, Search, which connects to the database, takes search terms, removes junk wordsand suffixes (s, ing, etc.) (both defined by an array). The class runs a query on each word for each field that the class is told to search, and based on the relevance of that field (as supplied to the class), points are awarded to returned items. If they come up again on searches for other words, they get more points. Using that base architecture, I then extend the class (e.g. class Faq extends Search) and define word groups in the subclass. Word groups act to broaden the search words in a thesarus like fashion (when the search term dvd comes up, movie, title, video, etc. are added to the SQL query via OR). This way each subclass can define it's own set of word groups applicable for that usage. The problem I am having is that far too many irrelevant items are coming up. When is my package coming? for example returns all kinds of junk because when is everywhere in a Faq. I am hoping that there is some internet resource that has a variety of tricks and rules to throw into a search architecture, but I am also interested to see if anyone can give me some of their personal experience and expertise.

Re: [PHP] class packages
Alex,
You suggestion about the config file is interesting, but while I go and
re-read your post, I am wondering how you would avoid class name conflicts.
Point and case, the only reason I am going after packages is because I have
a search class that is used for something else, and I want to not have to
name my other class SearchHelp.
I am going to run into conflicts if I include two class definitions for
search, am I not?
Thanks again for all of the insight!

No..,
In your example you are defining the search class in the Help
namespace, just like you would in ActionScript.
I don't think you can do that in php.
You would just use;
class Search{
// do stuff here
}
You can extend the class using;
class subSearch extends Search{
// do stuff here
}

A solution is to set all of these variables into $_SESSION, but the appeal of classes is that I might be able to maintain all of my information in a related location, and not in the session.

$foo = new Foo;
echo $foo;
$foo comes out as an object. Does this have to be done in two line like
this?:

function bar () {
return Bar;
}
}
$foo = new Foo;
$bar = $foo-bar;

[PHP] Advice: GET vs. POST vs. SESSION
I was hoping that some of you would be able to give me some advice. I have started creating a web application that makes heavy use of URL GET variables in order to solve a problem that I have had with POST in the past - namely, having to refresh the document and repost the variables when you use the browser's back button. So I enthusiastically have embraced GET variables, but am now having a struggle editing the URL variable string. So this is my question: is using URL GET variables that best way to avoid that browser back button effect? I have thought about using session variable extensively, but that I am going to have to be unsetting them all over the place. So - anyone have any advice?

[PHP] $_GET String Edit
Hey - this one should be simple. I am parsing some data and have $_GET variables in the URL stipulating on which record to start and how many records to display (these then get basses to the limit command in my database query). So here is the catch. I am trying to make a page navigation menu (we have all seen them, Page: 1 2 3...), and I would like to continue doing this via the URL variables. Right now, each of the page numbers is a hyper link is set like this: page.php?.$_SERVER[QUERY_STRING].more variables here. The problem, however, is that those variables are a string. If the variables that the menu defines are already in the string, it doesn't update them, it just adds more definitions to the URL. How have you people dealt with this? I am sure that there is some elegant solution and I would love to know what it is.

Re: [PHP] $_GET String Edit
Sorry for the confusing initial request. You were correct in assuming that I am generating URLs like: page.php?foo1=bar1foo2=bar2foo1=bar3foo2=bar4 So I suppose the consise follow-up question is how can I get a hyperlink to change one of those varibles in the string. In the past I have just tacked a varible on to the end of the string, but I don't want to be redundant. Thanks again.

I had a hard time interpreting your question, but I think you're saying that you are generating URLs like this: /page.php?foo1=bar1foo2=bar2foo1=bar3foo2=bar4 And, you're wanting to not duplicate variables in your URL, correct? You could always keep your query string in an array or something. This would allow you to update values in the array prior to the end of your script. You can start this array using $_GET: $query = $_GET; Of course, you might want to rather filter this data on each page, so that you don't spread tainted data more than necessary. Regardless, this will allow you to update values in your query string. If you want to update foo1, you don't have to care whether it's already set: $query['foo1'] = 'newvalue'; Hope that helps.

[PHP] URL Variables
Is there a way to preserve URL variables and have a link simply add a new variable to the end? I am tabulating data and I have URL variables defining which dataset to view and in what way to view it. I would now like to set the SQL statement up with a limit and add some Previous, Next commands, and even paging numbers, but how should I go about setting up the link so that the existing URL variables are preserved?

[PHP] Loop Question
Hi! I am trying to loop through two different database calls with two for
statements, one embedded in the other.
for ($i; $i $codeset_rows; $i++)
{
$codeset_row = $this-database-fetch_array($codeset_query);
$codesys_query = $this-database-query(select
codesys.codesys_index,
codesys.code_name,
codesys.code_value
from codesys
where codesys.codeset_ID = .$codeset_row['codeset_ID']);
$codesys_rows = $this-database-num_rows($codesys_query);
for ($j; $j $codesys_rows; $j++)
{
echo Blah, blah, blah;
}
}
The current set up means that the first loop should cycle twice, and the
second loop should cycle 6 times the first time and 2 times the second.
So here is the question: $j doesn't unset when the loop ends. So when it
comes around the second time, $j still = 6 and since $codesys_rows = 2, it
skips the loop. I can fix this by putting an
if ($j)
{unset($j);}
right before the second loop. However, it seems that there should be some
more efficient way to do this.
Ideas?
Thanks!

[PHP] Foreach Array Help
Okay, total newbie when it comes to arrays, and I could really use some
help. I sure this will be an easy one for you veterans out there.
Here is the array ($code):
array(2) {
[total]=
int(1)
[assign]=
array(1) {
[1]=
array(3) {
[type]=
string(10) Transcript
[rows]=
string(3) 603
[codeapply]=
array(1) {
[1]=
array(3) {
[codeset]=
string(23) FFT 6 Level Code System
[code_rows]=
string(3) 302
[code_complete]=
string(1) 2
}
}
}
}
}
Here is the output code:
foreach ($this-code['assign'] as $assign = $details)
{
foreach ($assign['codeapply'] as $codeapply = $ca_details)
{
echo tr;
echotd;
echo$details['type']. .$assign;
echo/a;

echo$ca_details['codeset'];

echo/td;
echotd;
printf ( %.0d%%,
($ca_details['code_complete']/$ca_details['code_rows'])*100);
echo/td;
echo /tr;
}
}
Output error:
Warning: Cannot use a scalar value as an array
Warning: Invalid argument supplied for foreach()
Conceptually and practically I have been struggling with how to navigate
levels of the arrays which are defined by a variable (e.g.
$code['assign'][$i] for the assign ID and $code['assign'][$i][$j] for the
codeapply ID on the assign ID).

[PHP] Re: Foreach Array Help
First of all, thanks for the response.
Here is where I am getting lost:
In $code['assign'][1] - 1 is the assignment ID, and I would like the array
to be able to hold a billion of these different assignments all with
conceivably a billion codeapply ID as in $code['assign'][1]['codeapply'][3],
where 3 is the codeapply value. In other words, because each of these
items directly under assign and codeapply are arrays because they hold
sub-info, I have made the keys of these items the values.
So - am I approaching this whole array thing wrong?
Thanks.

You have two mutually exclusive possibilities there.
Probably, what you want to do is something like:
$code['assign'][$i]['aid'] = (assign ID);
$code['assign'][$i][$j] = (whatever you want here);
(which, for simplicity, translates into something like:)
$code['assign'][1]['aid'] = 1;
$code['assign'][1]['1'] = 11;
$code['assign'][1]['2'] = 12;
$code['assign'][1]['3'] = 13;
$code['assign'][1]['4'] = 14;
$code['assign'][1]['5'] = 15;
etc.

[PHP] Re: Foreach Array Help
Never mind - I figured it out.
While I was traversing like this:
foreach ($this-code['assign'] as $assign = $details)
{
foreach ($assign['codeapply'] as $codeapply = $ca_details)
{
}
}
I had set up $assign to be the key value, and likewise not be an array. I
changed it to:
foreach ($this-code['assign'] as $assign = $details)
{
foreach ($details['codeapply'] as $codeapply = $ca_details)
{
}
}
and it worked beautifully. Thanks to all of you who got me going in the
right direction.

[PHP] ImageColorAllocate() Problem
I am having a bizzare problem with the imagecolorallocate() function. Maybe
all of you can help me!
Here is the code:
$hex1 = 0x.$color{0}.$color{1};
$hex2 = 0x.$color{2}.$color{3};
$hex3 = 0x.$color{4}.$color{5};
$color = ImageColorAllocate($im, $hex1, $hex2, $hex3);
Simple enough! $color starts off as a hex color code minus the #, and then
is pulled into each of the 3 alpha values by way for the hex variables. It
is later outputted in text:
ImageTTFText ($im, $cursive_size, 0, $text1_x, $text1_y, $color, $font1,
$cursive_text);
Problem: The text is always black.
Something strange: If I just type in a randomly selected color, it works!
Is there some reason that the values in my variables wouldn't be passing?
Thanks in advance,
Jed R. Brubaker

You know, I am not sure if this will help, but I have a problem very similar to this in my debugger. When I run a script check through my WIN32 PHP module, I get errors related to imagecreate() functions. In a current project I use imagecreatefromjpeg() functions and get the same problems. Fortunately for me, once my scripts have gone up to the server they have worked fine. You might have the same luck! One other thing - you might want to check the image capabilities of your PHP's build. One server I worked on did not have the capabilities to work with GIFs or PNGs, so I had to do things with imagecreatefromjpeg() (as I mentioned above). Good luck!
