Help with Array!

I'm a tad ignorant of returning arrays. If I set a bunch of input text boxes in an array like so:

How would I go about returning it on the submit?

What is the correct PHP function and format to call the array on $_POST?

Thanks!!!

$_POST['description[$row['project_id']]']

with the proper escaped quotes, of course

When in doubt, try it, and then put this lovely piece of code in your target page:

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

Thank you so much for that <pre> thingy. That rules!

My problem still remains as far as displaying array members of the sub-array. Unfortunately, this suggested method didn't fly:

$_POST['description[$row['project_id']]']

Any other suggestions would be extremely appreciated!!!

Thanks!

This line:
<input type="text" class="content" name="description['.$row['project_id'].']">

Should be:

<input type="text" class="content" name="description[<?php echo $row['project_id']; ?>]">

Second:

When you are reading these values (in form handling script) use something like:

if(isset($_POST['description']) && is_array($_POST['description'])){
    while(list($key,$value) = each($_POST['description'])){
        //in $key is the key of the array item - or in this case the value of the $row['project_id']
        // in $value is the value of the array item - or in this case whatever is a value of the every given field
    }
}

Or I completely misunderstood what you are trying to do...

You have dispelled my ignorance in this area, however I still remain largely ignorant in other areas.....stay posted for future occurances of ignorance!!

This forum rules! Thank you so much.
