[Resolved] session to store multiple form submit

[anthill]

Hi

I'm trying to add items to an array each time the form is submitted so I will have an array of all options chosen from the picklist. This is instead of using radio or check buttons.

Problem i'm having, is each time the form is submitted, the value of the items in the array doesn't increase.

To help, here is the code i'm using:

<?
session_start();

if (!isset($_SESSION['values'])) 
    { 
    $_SESSION['values'] = array(); 
    } 

if (isset($HTTP_GET_VARS['equipment']))
    {
    $_SESSION['values'][] = $HTTP_GET_VARS['equipment']; 
    }

echo count($_SESSION['values']); 




?>
<form method="get" action="index.php">
<select name="equipment" size="1">
<option>Television</option>
<option>Camera</option>
<option>Computer</option>
</select>
<input type="submit" value="save">
</form>

I'm guessing I need something to keep increasing the SESSION['values'][] to SESSION['values'][$var], where $var increases on each submit, but can't get anything to do it.

Any help is much appreciated, thanks

I think I'm confused as to what you are trying to do, that works for me count() keeps increasing as items are added to the array -

print_r() shows

Array ( [values] => Array ( [0] => Camera [1] => Camera [2] => Computer [3] => Television ) )

As I keep submitting the form.

ahh yes, it does work. Hmm so why wouldn't that work on the server at work!

Hi,

which session settings do you have on the server at work ?

Depending on the session settings you might need to e.g. add a hidden input to the form with the session name and id. Something like

<input type="hidden" name="<?PHP echo session_name(); ?>" value="<?PHP echo session_id(); ?>">

EDIT: Make sure that session.save_path is set to a valid directory in php.ini

Different version of PHP?
Remember:
PHP <= 4.0.6 = $HTTP_SESSION_VARS
PHP > 4.0.6 = $_SESSION
and if PHP <= 4.0.6 and register_globals = on then this globals will not work at all (took me a week to figure that out). Then session_register() has to be used.

Hi

I'm still having problems with this (at work). Thanks Pingu, i've noticed that I have "PHP <= 4.0.6 = $HTTP_SESSION_VARS" and i need to use session_register(), but i don't know if i'm using it correctly. Here's my code:

<? 
session_start();


  if(!session_is_registered("values"))
      {
      session_register("values");
      }


if (!isset($HTTP_SESSION_VARS['values']))  
    {  
    $HTTP_SESSION_VARS['values'] = array();  
    }  

if (isset($HTTP_GET_VARS['equipment'])) 
    { 
    $HTTP_SESSION_VARS['values'][] = $HTTP_GET_VARS['equipment'];  
    } 

echo count($HTTP_SESSION_VARS['values']);  




?> 
<form method="get" action="index.php"> 
<select name="equipment" size="1"> 
<option>Television</option> 
<option>Camera</option> 
<option>Computer</option> 
</select> 
<input type="submit" value="save"> 
</form>

Any help is much appreciated!

D'oh, this works although perhaps it could be neater???

<? 
session_start();


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


if (!isset($HTTP_SESSION_VARS['values']))  
    {  
    $HTTP_SESSION_VARS['values'] = array();
    $values = $HTTP_SESSION_VARS['values'];
    }  

if (isset($HTTP_GET_VARS['equipment'])) 
    { 
    $HTTP_SESSION_VARS['values'][] = $HTTP_GET_VARS['equipment'];
    $values =  $HTTP_SESSION_VARS['values'];
    } 

echo count($values);  




?> 
<form method="get" action="index.php"> 
<select name="equipment" size="1"> 
<option>Television</option> 
<option>Camera</option> 
<option>Computer</option> 
</select> 
<input type="submit" value="save"> 
</form>
