[RESOLVED] Accessing Checkboxes

[Thora_Fan]

So this is something I probably should have learned a long time ago when working with forms, but I've never had the need till now.

I have a group of checkboxes representing states, such as:

<label><input type="checkbox" name="State[]" value="AR" />Arkansas</label><br />

<label><input type="checkbox" name="State[]" value="CA" />California</label><br />
<label><input type="checkbox" name="State[]" value="CO" />Colorado</label><br />
<label><input type="checkbox" name="State[]" value="CT" />Connecticut</label><br />
<label><input type="checkbox" name="State[]" value="DE" />Delaware</label><br />
<label><input type="checkbox" name="State[]" value="DC" />District of Columbia</label><br />
<label><input type="checkbox" name="State[]" value="FL" />Florida</label><br />

etc...

The problem I am having is accessing the State data after the form is posted. Even though there are several boxes checked, I get an error in PHP when I try to access the $State array, such as:

extract($_POST);

foreach($State as $key=>$value)
{
   // blah
}

generates the error Warning: Invalid argument supplied for foreach()

All of the other $_POST data is passing correctly. What the hell am I doing wrong?

Hrm. Works fine for me.

Did you try doing a print_r($_POST); to manually examine the POST'ed data?

Double check for typos as well, though I don't see any in the code you posted.

Odd. All of a sudden today it works. I swear I'm not doing anything differently. I don't know what the deal is. Thank you anyway though.
