Replacing variables in Session Arrays

kopar

Okey Dokey...

I'm making a set of forms (something like 100 input fields that must be filled out per user). When I hit the submit button, the fields are placed into an array ($form1[fname], $form1[lname],...). That array has been declared as a session variable.

The problem happens when I want to change one of those fields and the corresponding value. IE, the user has forgotten to put something into the 'Color of Underwear' field. If I declare it as a $_SESSION or session_register() variable, it seems to be unchangeable.

Is there a way to override this? Or some way to work around it cleverly?

//Here's a sample of what's going on:

<?php
	session_start();
	session_register('form2');
?>
<body>
<html> 
<form action="<?=$PHP_SELF?>" method="post" name="someForm" id="someForm">
  <p> 
    <input name="form2[name]" type="text" id="form2[name]">
    name<br>
    <input name="form2[color]" type="text" id="form2[color]">
    color<br>
    <?
	print "Form2 : <br>";
	print_r ($form2);
?>
  </p>
  <p> 
    <input type="submit" name="Submit" value="Submit">
  </p>
  </form>

<p><a href="<?=$PHP_SELF?>">Click here to continue</a> </p>
</html></body>

Hi,

Here's what i think you are doing wrong

First time you load the page
start of session
register form2 (at this time no value is in form2)

when you use the submit button it will reload the page with form2 set to some value

When you start the session it sets all session variables with their session values.
REMEMBER THAT AT THE END OF THE FIRST PAGE FORM2 WAS EMPTY
So the sessions overwrites variable form2 with his empty session value.

oooooohhhhh! I see what's happening there! Great 🙁 Now I gotta try and get it to set the session variables before the session starts?

Try this

<?php
session_start();

if ( issett($_POST('submit'){ //true if form has been submitted
       $form2=$form_submit;

       if( !session_is_registered('form2'){
                session_register('form2');
       }
}

<body>
<html>
<form action="<?=$PHP_SELF?>" method="post" name="someForm" id="someForm">
<p>
<input name="form_submit[name]" type="text" id="form2[name]">
name<br>
<input name="form_submit[color]" type="text" id="form2[color]">
color<br>
<?
print "Form2 : <br>";
print_r ($form2);
?>
</p>
<p>
<input type="submit" name="Submit" value="1">
</p>
</form>

<p><a href="<?=$PHP_SELF?>">Click here to continue</a> </p>
</html></body>

Didn't try it, probably needs some minor fixes

That would work... Kinda, but I think I got it figured out another way.

My mistake was using the session_register() for my array. Instead, I used $SESSION, here's how:

<?php
	session_start();
	$_SESSION['form2'] = $_POST['form2'];
	$_SESSION['counter'] ++;
	print $counter;
?>
<body>
<html> 
<form action="<?=$PHP_SELF?>" method="post" name="someForm" id="someForm">
  <p> 
    <input name="form2[name]" type="text" id="form2[name]">
    name<br>
    <input name="form2[color]" type="text" id="form2[color]">
    color<br>
    <?
	print "Form2 : <br>";
	print_r ($form2);
?>
  </p>
  <p> 
    <input type="submit" name="Submit" value="Submit">
  </p>
  </form>

<p><a href="<?=$PHP_SELF?>">Click here to continue</a> </p>
</html></body>

That replaces everything, each time the page is called. Works like a charm (Thanks to bigfoot on #php / QuakeNet!!!)
Thanks for the suggestion tho, very creative 🙂
