list

Hey, I'm having a issue with using a listbox.. Am I doing something wrong??

Heres my HTML:

<select style="height:100px;width:250px;" name="countries[]" multiple>
		<option value="US">United States</option>
		<option value="UK">United Kingdom</option>
		<option value="CA">Canada</option>
		<option value="AU">Australia</option>
	</select>

and my PHP:

$countries = $_POST['countries'];
$countries = implode(' | ', $countries);

 

I'm trying to set it up so I can insert the data as: US | UK | CA.

But, when I submit the form, I get these errors:

Notice: Undefined index: countries in /Applications/MAMP/htdocs/mynewscript/admin/cp/add.php on line 30

Warning: implode() [function.implode]: Invalid arguments passed in /Applications/MAMP/htdocs/mynewscript/admin/cp/add.php on line 31

 

Thanks in advance!

do

print_r($_POST); 

just before you set the $countries 

this will tell you whether it's being posted or not. Everything looks correct. But it's possible you didn't set your form to post. Or this is outside of the form.

Its posting it fine.. The array is posting out: => [countries]

and it is inside the form, and I have it wrapped with a if isset statement. I've done it before, worked fine. Not exactly sure why its not working.

you have the brackets after countries. So you're countries would be index 0 of $_POST['countries']  drop the brackets or refer to $_POST['countries'][0];
