Hi all,

I have a form that has has an array of information.  Mulitple checkboxes can
be selected.

Choose the colors:
<input type="checkbox" name="Colors[]" value="green" checked="checked" />
<input type="checkbox" name="Colors[]" value="yellow" /> Yellow
<input type="checkbox" name="Colors[]" value="red" /> Red
<input type="checkbox" name="Colors[]" value="gray" /> Gray

When processing the form..

echo $_POST['Colors'] . '<br />'; // outputs 'Array'

if ( isset($_POST['Colors']) ) { 
     $_POST['Colors'] = implode(', ', $_POST['Colors']); //Converts an array
into a single string
   echo "Colors you chose: {$_POST['Colors']}<br />";

I get the following error when using the implode function.

Warning: implode() [function.implode]: Bad arguments

What I doing wrong ?

Thanks in advance.
