php explode

[jessnoonyes]

Hi guys. I've been getting help in the javascript forum putting together a php/javascript quiz. I had it functioning ok but it wasn't working in IE7 and they helped me rewrite it. However, before I had the variables being passed in hidden checkboxes. Now there are no checkboxes and I'm struggling with php explode as the javascript guys suggested I use.

What am I doing wrong?

<form action="money_quiz_results.php"  method="post">
<input type="hidden" name="userSelections">

<tr>
				<td>Anxious</td>
				<td>Prone to blame</td>
				<td>Highly Emotional</td>
			</tr>
			<tr>
				<td>Lives in the past</td>
				<td>Financially irresponsible</td>
				<td>Seeks rescue</td>
			</tr>

on the results page:

PHP Code:

<?php
$userSelections = explode(";"); 

$innocent = 0;
if ($_POST['anxious'] == 'yes')
$innocent++;
if ($_POST['trusting'] == 'yes')
$innocent++;
if ($_POST['feels_powerless'] == 'yes')
$victim++;
if ($_POST['financially_irrisponsible'] == 'yes')
$victim++;
if ($_POST['seeks_rescue'] == 'yes')
$victim++; .....

If you don't have any checkboxes then you won't have any form data to capture in your page.

In your Javascript thread 12 Pack Mack mentioned that with his code your variables would be passed within the userSelections field as a comma delimited string, meaning what you have to do is:

$userSelections = explode(",", $_POST['userSelections']);

$userSelections will then be an array holding your variables.

Awesome, thanks for helping! I have the results page like this:

<?php
$userSelections = explode(",", $_POST['userSelections']);

$innocent = 0;
if ($_POST['anxious'] == 'yes')
$innocent++;
if ($_POST['trusting'] == 'yes')
$innocent++;

But it isn't showing anything. Here's my test page. Only the first few items have been changed but you'll see if you click on them no results are shown on the next page. What did I do wrong?

[venegal]

$_POST will only contain 'userSelections', which should contain all your variables, so calling $_POST['something else'] doesn't do anything. Try echo var_dump($userSelection); in order to see what's in there and how you can use it.

[jessnoonyes]

It says NULL

The results page is working for me:

On the left you can see the post data that was sent.

Hey awesome! Why won't it do that for me? It won't work in either Firefox or IE7. The values are always zero and the var_dump says NULL.

*the values will still be passed if there's a checkbox that's checked...

[soak]

That was on linux but I've just tested on Windows XP, both firefox and IE7 and it works on both. There are some javascript errors still though.

Sorry, I mistyped. echo var_dump($userSelections);

I didn't have a look through the Javascript code though, just the comment that went with it.

var_dump return void
that echo is useless or I miss something and don't understand what you want to do.

You're right, thanks. Judging by the time I posted, I was probably drunk.
