Forms... <Select multiple="multiple">

Sorry for the bad topic-line.... but its the best desc i could think...

The form contains this:

PHP Code:


		
			
<select name="genre" size="5" multiple="multiple" id="genre">

   <option>[New Genre]</option>

   <option>Industrial</option>

   <option>Rock</option>

</select>

I made a quick script to show the POST variables...

PHP Code:


		
			
<?PHP 

  foreach($HTTP_POST_VARS as $key => $value) 

   { 

     echo $key." = ".$value."<br>\n";

   }

?>

the POST variable shows the last selected item... for example, if i select all three, it returns "Rock"...

Any idea how i can retreive all selected items?

hmm,...maybe try something like this...

Code:

<select name="genre[]" size="5" multiple="multiple" id="genre">

you may be setting the value for genre to the last selected entry. by setting it as an array it should allow you to select and display multiple. give it a shot.

Heres a little tip:

You have the following code to go though your post array

PHP Code:


		
			
<?PHP 

  foreach($HTTP_POST_VARS as $key => $value) 

   { 

     echo $key." = ".$value."<br>\n";

   }

?>

an easier way is to use the print_r() function

PHP Code:


		
			
 print_r($_POST);
