Re: [PHP] Code for off-site Maintenance?
Good comments made by all, no doubts. Something said by Justin though, sticks out above the rest. I strongly recommend to everyone to never, EVER edit or manipulate LIVE code! I know we're all good at what we do, but accidents happen (perhaps you didn't specify a WHERE clause in your delete statement for your database? Whoops!). Like Justin, my process is to test, test, test, upload, and test some more. Extra time spent now could possibly mean less time spent correcting stupid mistakes.

Re: [PHP] select multiple
It depends on how you want them to be in the database.

Then just use explode() with the same arguments (although replace array with the comma_seperated string) to go back to an array. HTH!

Re: [PHP] Disabling Browser BACK button
There is never a way to disable back, forward, home, etc buttons. They all have shortcuts that will ALWAYS work, so there's really no point. Additionally, it's all nice and good that your site works fine without using cookies, and don't take this offensively, but if the client cannot use the back button without getting mishapen results, then it doesn't sound as if the site is designed very efficiently. Just my opinion.

Re: [PHP] String Question
Give this a whirl:
?php
$string = abcdefghijklmnopqrstuvwxyz;
$len = strlen($string) // in this case, 26
for($i=0; $i $len; $i+8) {
$str_array[] = substr($string, $i, 8);
}
for($i=0; $i count($str_array); $i++) {
echo $str_array[$i] . br\n;
}
?
I haven't tested it, but in theory it should find the length of the string (26), loop
through it as long as $i is less than 26, incrementing 8 at a time. Each time it goes
through, $str_array[] is fed a new element, which is a substring of $string that
starts at $i (0, 8, 16, 24, etc) and grabs 8 characters. So here is how the data
should be retrieved.
1st loop: 0-7 (8 elements)
2nd loop: 8-15 (8 elements)
3rd loop: 16-23 (8 elements)
4th loop: 24-26 (3 elements)
Let me know how it works out for you :o)

Re: [PHP] Array variable in Javascript PHP
PHP cannot read a JavaScript array, simple as that. There are many workarounds,
depending upon your situation. You can, for instance, create a function that is
called onsubmit, that will take any values in checked checkboxes and put them into a
comma-delimitted string inside a hidden form element. That string is then passed to
the PHP page, where it can be parsed (ala implode/explode) and put into a new array.
I hope that made some sense :o)

Hello:
In a form I am using a series of check boxes for a number of lists. Some
calculations has to be done on the client side using Javascript depending
upon the check box values. For this I am using a single variable name
(array) for the check boxes in a list and another for the next list and so
on. The format I have used is
input type=checkbox name=list1 value=Education onclick=addList()
Education
input type=checkbox name=list1 value=Profession onclick=addList()
Profession
I can access these variables from Javascript as list1[0] list1[1].
(document.form.list1['0'].checked document.form.list1['1'].checked
But when this form is submitted to the PHP script I am getting only the
last value. list1 = 'Profession'. I am not getting an array of values.
?
for ($i=0; $icount($list1); $i++)
{
$listall .= '$list1[$i],';
}
?
How can I accomplish both these operations? I cannot use single variables
names for each item in the form, because it is more than 1000. Also I want
to use both Javascript PHP operations. Please help to solve this issue or
suggest some other ways to accomplish this business logic.

That's not entirely correct, though. If you are using output bufferng, then you can. Also, for example, say this is your file, with the makeshift line representing the top of the text editor: Start ?php header(Location: index.php?msg=blah); ? -End That will produce the same error as before, since a hard return was entered before the parser began it's work, therefore finishing the headers and sending the data to the client for rendering.

Re: [PHP] PHPMyAdmin interface
It's not normal that I've come across. Any hosting company I've ever dealt with (albeit not many, still three different ones), have all offered phpMyAdmin for interfacing with MySQL. And honestly, if the host REQUIRES you to do it, then they aren't worth hosting with. You'll find that will transcend into other areas of how they do business (i.e. technical support tickets, etc). Currently I'm hosting with http://www.websytz.com, and they have good prices. Another of my sites is on http://www.dzones.com, and they're very good as well. WebSytz' control panel flat out sucks, but it's usable. DZones has an incredible control panel, but they just didn't have the price I wanted for my current website. There's plenty out there, and since you pay monthly, you lose nothing by switching to another company. The choice is yours.

This is not a valid way to check if the query has returned anything.
mysql_query() returns FALSE on error. So if there was no error but there
also wasn't anything returned then the object stored in $result wiill more
than likely evaluate to TRUE. For the determining factor you should count
the number of rows with mysql_num_rows($result). If the returned value is
zero then you know it hasn't returned anything.

I can almost guarantee that it's not the second line that is failing,
the problem here is that $result is not containing naything, and that is
normally due to the fact that you are not connecting to the db, or the
table tablename is not there.
I use the following format as my standard MySQL connect and query
snippet:
$link = @mysql_connect(localhost,$username,$password) or die ('Could
not connect!'); //@ suppresses the default error message generated by
this function and the or die() bit kills the script right then and
there should it not be able to connect.
mysql_select_db(YOUR_DB_NAME,$link);
$sql = select * from your_table_name;
if ( $result = mysql_query($sql)) { // checks to see if $result
contains anything before it even tries to fetch an associative array
from it.
$row = mysql_fetch_assoc($result);
} else {
echo Empty result set!;
Note also that I use mysql_fetch_assoc and NOT mysql_fecth_array, as 9
out of 10 times, you don't need the array element id's that is returned
by mysql_fetch_array.

break;
case add_file:
// what to do in the even that a file needs to be added

That's not quite right. Php's variable scoping is different than most langauges.
Variables inside a function are always local, even with register_globals on (this has
something to do with Rasmus' life experiences at IBM). So you would need to use global
on a variable inside a function (unless it's passed in) and except for the 'magic'
global arrays, $_POST, $_GET, $_COOKIE, $_SERVER, etc

I'm using mysql_fetch_array() and I want to foreach only the assoc. part of
the array without using mysql_fetch_assoc():
foreach ($arr as $key=$value) {
echo $key:$value;
}
But of course it show both the indexed array and the assoc array contents.
Is there an existing function to check this, or should I do one of these
things inside the foreach loop:
A) set $last=value and just check if $value = $lastval
B) check if the $key is just a number or just a string
C) $key += 1

[PHP] Of Jobs and Certs
Howdy everyone, I'd like to get everyone's input on Jobs and Certs. I know there are a couple Certifications for web developers out there, such as the CIW and CWP certifications. Here are my questions: 1. What is the best method to go about becoming certified? 2. What is the best way to go about getting into the web development industry? 3. If you have ever taken online courses relating to web development, what is your opinion on them? Good, bad, ugly? 4. Which certification is most beneficial? I know that CWP requires work experience before becoming certified past certain points, and CIW does not require this. 5. Why can't I remember what question five was? Doh. At any rate, I'm current a data entry clerk, but have quite a bit of web experience (none at a job, though), and I know that I have TONS more to learn, but I am very passionate about it and want to be able to do it as a career. I just don't know where the hell to start, and I know that some of you might be able to offer some advice in this area. Thanks in advance!

RE: [PHP] Classes vs. Functions
To add to the below, object classes, can have their own set of functions, called methods. These methods are specific to the function, and ALL functions within a class treat any properties (variables) within the class as global. So if you have a class Car with two properties (Make and Model), then those two properties can be readily accessible to any method within the class. At least I think that's how it works. I'm not all that knowledgeable on the subject :o) Martin Clifford Homepage: http://www.completesource.net Developer's Forums: http://www.completesource.net/forums/ Jay Blanchard [EMAIL PROTECTED] 07/16/02 10:51AM [snip] Could someone please explain the difference between classes and functions and how to use a class.

Re: [PHP] Classes vs. Functions
Here is a sample code (don't take this as gospel... Jay knows more about OOP than I
do, I'm sure!):
class Car {
var $make;
var $model;
function setMake($x) {
$this-make = $x;
}
function setModel($y) {
$this-model = $y;
}
}
$make and $model are the properties of the Car class, and setMake() and setModel() are
the methods of the Car class. You don't actually get an object until make a *new*
one. Like this:
$passat = new Car;
$passat-setMake(Volkswagen);
$passat-setModel(Passat);
This assigns the new object, passat, the properties relating to it's make and model,
using the methods setMake and setModel. I'm sure this is right, but I'm sure I'm
probably wrong (hehe, confused?). I'm also sure someone will correct me if I am! :o)

Re: [PHP] Classes vs. Functions
I'm still trying to figure that out, but the fog is clearing slowly but steadily :o)
From what I've heard on this and other lists, it's all a matter of preference.
Obviously those that come from an object-oriented environment (Java, etc), will lean
toward this method, while others stay with the procedural side of things (using
functions). It's all a matter of preference, and just yet I haven't decided which is
more useful :o)

if (!isset($id))

// Create a page saying ID not found, goto index
writeHTMLTag();
writeHeader(Error, never);
writeBodyTag();
writeLogoNav();
echo h1Error: A hospital ID was not found./h1

;
writeFooter();
writeHTMLTagCloser();
// what command can I use to end the script right here?
}
else
{ // Run MySQL stuff and display page
}
My question is what command can I use to end the script [inside the top

Re: [PHP] Newbie Question on Efficiency
Unless the file is getting retartedly big (10-20K), then I wouldn't separate them.

I have a large number of frequently used functions that I'm trying to find a good way to organize. The method I'm thinking of using is to simply create a .php file called, for example, functions.php. Then, just include the file at the top of each page that needs any of the functions, and just call them as needed. My question is this- if that file gets very large with tons of different functions, is that an inefficient method? I'm not entirely clear on how PHP is parsed and passed to the client. I assume it would be best to divide up the functions into multiple files (ex. dbfunctions.php, etc.), but is that still the best method?

Re: [PHP] A question of style ...
I see no problems whatsoever in utilizing an intermediary script to do processing of information. However, there IS a problem when this script sets flags that are unwanted by the client. An example of a good intermediary script application would be as below. Person A and Person B both remotely log into their website's Content Management System. They both navigate to the same file on the server, because their boss told them it needs updating. Person A clicks on the link to edit the file first, thereby setting an intermediary script into action which sets a flag, say checked_out to true. Person B across the hall is denied access to this file because Person A already has it checked out. This is much in the tradition of DreamWeaver FTP. The above is a great example of how intermediary scripts can be used to help avoid critical misunderstandings. You do NOT want two people to edit the same file at the same time, otherwise it'll get messed up REALLY fast. In your example, though, if the agent simply wishes to view the customer's information, but has no interest in contacting the person at all (perhaps for research purposes), then the flag that says that the agent is, has or will be contacting the customer is obtrusive. Overall, I think the coding style is very good, and you're right that it does in fact make code much easier to interpret. However, there is a big difference between an intermediary script being helpful, and it being a hinderance. Just my $20.00 (big mouth, you know) Martin Clifford Homepage: http://www.completesource.net Developer's Forums: http://www.completesource.net/forums/ Jay Blanchard [EMAIL PROTECTED] 07/12/02 09:40AM Howdy group, Over the past couple of days I have come under some fire for my style of coding, most particularly the use of PHP scripts to process information between pages or interfaces shown to various users. An example; An agent goes to an interface that reveals a list of customers from a database. These customers have provided referrals which now reside in a database. The agent selects a referral which is processed by an intermediary script which sets a flag in the database saying that this agent is, has,or will be contacting this referral (to prevent duplicate contact). Then this redirects to the referral's interface where the details about this referral are revealed. Interface A ++ | Customer | | Submitted | | Referral | ++ |+--+ +---| PHP Script | | (for processing) | +--+ | Interface B | ++ | | Referral | | | Info |--+ ++ While this is a rather simplistic example (I use some intermediary scripts that are much more complex, some that call other script if the situation warrents it) I have found that for many applications this makes the code easier to maintain, gives me a way ID certain processes when something breaks (I use a lot of error logging), and also prevents some code from being aborted by the user when the results of doing something like that might be undesirable. I know that this might start a holy war, but it is likely that discussion on this would enhance all of our coding styles. I realize that this may not help me strengthen my position with regards to the fire I have come under, but I had to ask. Thoughts? Thanks! Jay * * Want to meet other PHP developers * * in your area?

Re: [PHP] ' giving problem while inserting in table.
Use addslashes() on ALL strings before inserting them into your database. Then, on
your frontend, extract the data and use stripslashes() on all strings.

Hi,
I am making a faq maintenance system using mysql and php.
To insert a entry in to a faq table i am using the following query:
-
INSERT INTO faq_table_netvd (id,question,
answer,netvcr,netdetector,add_date,mod_date,keyword,category,display,attach_
id)
VALUES ('0','$frm[question]',
'$frm[answer]','$frm[netvcr]','$frm[netdetector]','$frm[add_date]','$frm[mod
_date]','$frm[keyword]','$frm[category]','$frm[display]','$frm[attach_id]')
);
---
now the problem is when $frm[question] has some string like: why i can't
eat.
i get the following error:
MySQL Error: You have an error in your SQL syntax near 't eat?' ,answer =
'Please recheck the power of your specs:)' ' at line 3.Putting a '\' before
' (e.g. \')solves my problem...but when i open the same quesion to edit it,
again i have to put backslashes where ever i find ' in the quesion or
answer.
Can anyone please suggest a solution to this.
thanx and regards
anil
[please ask if i havent explained the problem fully]

Re: [PHP] Final Year Computer Science Project involving PHP
If completely developing a fully functional and optimized E-commerce site isn't good enough, I don't know what is. I can understand how it may not necessarily be innovative (though it could have innovative features), but designing such a site would prove to anyone I know that you have a great knowledge of the language the site was created in. As for original ideas, good luck. You'll come to find that anything you can think to do has already been done. You're best bet may be to look around some sites on the 'Net and try to vastly improve what has already been done. Projects that find solutions? That could be anything from a Weight Loss Tracking System to an advanced encryption/decryption algorithm.

I will start next autumn my third year of Computer Science studies. I have to carry out a large programming project in this final year. These projects are supervised and assessed via a dissertation and an oral presentation. The project alone counts for 20% of my whole degree, so it is quite important. A variety of project proposals have been made available for our consideration already but they all look very dull and boring. We are also encouraged to come up with our own project ideas. The onus is on us to define the problem boundaries, to investigate possible solutions, and to present the results verbally, in writing and (possibly) to demonstrate in action. They like having projects that find solutions (or improve a current sloution) real life problems. This summer, I am doing an internship in a Swiss IT company, working on a Content Management System implemented with PHP and MySQL. This will obviously give me some valuable experience with these languages (I sort of already learn them quite well...) and most of our tuition in Uni is based on Java. If you can think of an interestin final year project involving hese languages, it would be very kind to share it with me... In order to obtain a very high mark, the project needs to be challenging.

[PHP] Re: Customise Index page using PHP????
The easiest way to accomplish that is by using switches. Here is an example:
switch($pageid) {
default:
include(default_page.inc);
break;
case 18:
include(page_18.inc);
break;
}
With that in your index.php page, it will look for the variable $pageid, and depending
on what it is set to, display the appropriate information. In this instance, it will
display the default index page by default (if $pageid is empty), or page_18.inc if
$pageid = 18.
Hope that helps :o)

Re: [PHP] Re: session error ... I think
When you request a page, for instance, php.net, your web browser sends HTTP headers to the server that holds php.net on it. When the server receives these HTTP headers, it knows which page is needed, and sets up it's own headers to send back to the browser, such as location, file types, etc. It then sends back the requested page with all the appropriate header information to the browser, which displays the page. Where your question comes into play is somewhere in the middle. You can set the HTTP headers only AFTER the request to the server has been made, but has to be BEFORE the page arrives at the client browser for display. So, when we all say that there can be NOTHING output to the HTML file before the headers are sent, we mean it literally. For example: Open up Notepad. Hit return once, then type this in: ?php header(Location: index.php); ? Upload it and run it. You'll get an error. Why? Because you sent a hard return to the HTML output BEFORE the header was sent. Hopefully this is not all jumbled an unhelpful. Heh :o) Good Luck!

Thus headers that were to be sent must have already been sent. I interpret this error message as Something other than headers has already been sent so you cannot send headers now., (but then I have been known to be wrong).

Re: [PHP] Newbie continued..wrong datatype
As far as I'm aware, the first argument to the in_array() function is the needle (what
you're searching for) and the second is the array to be searched through (the
haystack).
So if $type represents what you're searching for, then it would be written as:
in_array($type, $CheckArr);
If you supply the third argument as TRUE, then the search becomes case sensitive, I
believe.

Re: [PHP] Accessing multiple List/Menu values
Have you tried like this? select name=list[] size=5 multiple option value=yahooYahoo!/option ... option value=phpnetPHP.net/option /select Then access the array on the processing page. Martin Joseph Szobody [EMAIL PROTECTED] 07/10/02 02:02PM This is sorta OT, but involves PHP. I have a fairly large List/Menu on a form, which allows for multiple selections. I want users to be able to use cntrl/shift-click to select a bunch of items. Let's say this List is called 'list'. Now when I submit the form, how does the processing script access all these different values in 'list'? If I try to echo '$list' it only show *one* of the selected items from the list. I've tried treating it as an array ($list[0], $list[1], etc), but that doesn't work either. How do I get at the different values?

Re: [PHP] Dumb session / cookie / password questions
Firstly, you should ALWAYS use an encryption algorithm for passwords. For my site, I
used md5() and match with that. That way, even if someone does get a hold of the
encrypted password, it's not in their best interest (or maybe it is, if they're bored)
to crack it.
I haven't testing the following out, but it might work if someone wants to be a
smartass and type out
index.php?user=admingodpass=adminpass[EMAIL PROTECTED] in which they know
the info.
?php
if(!empty($_GET)) {
header(Location: $PHP_SELF);
}
?
Putting that at the top of the page would check to see if any information was sent to
the page from the $_GET superglobal, and if it was, reload the page without any URL
extensions. It sounds good in theory, though I haven't tested it, so it might not
work as I think it should (it NEVER does!).

I am a little confused about storing stuff in cookies/sessions and how to
prevent spoofing of them.
A user logs in, his e-mail address or user id and password(md5'ed) is
checked against my database.
Assuming it matches, I then set a cookie with the users id + email.
What is to stop someone from spoofing that cookie? I obviously don't want
to put the password in a cookie .. can someone point me in the direction of
an article about this? I've searched around, but I'm not finding stuff
about in a preventing spoofing / security aspect.

Re: [PHP] UNSETing Session Variables
You only have to register the session variables once. If you need to register the
same variables again (such as for a different user), then you should use
session_destroy() before registering the variables again.
The variables should be available throughout your pages as long as session_start() is
done before ANY output goes to the HTML. It's usually best to have it as the FIRST
thing on your pages.

I fear you're missing something fundemental here. The active session
needs to be requested for each script. So session_start() needs to be
called at the top of each script (or at least before any output).
Example..
page 1

?
session_start();
$myvar = foo bar;
session_register('myvar');
// or //
$_SESSION['myvar'] = $myvar;
?
page 2

far:(

I don't personally see TOO much wrong with passing the encrypted password along, especially since you aren't displaying it in the URI's query string. BUT, if someone DID get a hold of the encrypted password, they can run millions of words through md5() until one matched. I would hope that people aren't bored enough to do that, but past actions have proved that wrong. The magic line: session_start(). That's it.
