[SOLVED] Foreach Problems

[StormTheGates]

Ive got a list of checkboxes that I need to loop through. So heres what Ive done so far.

 

<?php
echo "$_POST[idofcar]";
foreach ($_POST['idofcar'] as $key => $value) {
    die("This is working!");
}
?>

 

When this is run the ID of the car from the checkbox will run fine, and say 19 or whatever. But then it will not die which means that it is not going into the loop. Any ideas why?

What does your form code look like?

 

Also, what is the output of

print_r($_POST['idofcar']);

I find that for debugging purposes, this line is much more useful:

 

echo '<pre>' . print_r($theVariable, true) . '</pre>';

 

As for your specific question, if the echo statement prints 19, then that means $_POST['idofcar'] is a string or number, which is a scalar value.  foreach works on arrays, not scalars.

Also, just a guess, but your HTML probably looks like:

 

<input type="text" name="idofcar" />
<input type="text" name="idofcar" />
<input type="text" name="idofcar" />
<input type="text" name="idofcar" />

 

you will need to add [] to them...

 

<input type="text" name="idofcar[]" />
<input type="text" name="idofcar[]" />
<input type="text" name="idofcar[]" />
<input type="text" name="idofcar[]" />
