[Resolved] multiple item select box - Mysql insert

[freebie]

I'm having problems with a multiple item select box. It's weird because I've done this without any problems in the past (it might be a configuration issue).

Right now, I'm debugging to try to figure out what's going on but I'm stumpted. Here's the info:

Form Field as cut from post-rendered source:

<select name="CompanyLogins[]" size="5" multiple id="CompanyLogins" >
<option value='2_8886252'>John Doe</option>
<option value='4_15747833'>Brian Jackson</option>
<option value='6_3962892'>Jane Doe</option>
</select>

Now for debugging, I'm using the following code to output the information received on the PHP side

echo gettype($_POST['CompanyLogins'])."<br>";
echo $_POST['CompanyLogins'] . "<br>";
echo $_POST['CompanyLogins'][0] . "<br>";
echo $_POST['CompanyLogins'][1] . "<br>";
echo $_POST['CompanyLogins'][2] . "<br>";
echo $_POST['CompanyLogins'][0][0] . "<br>";

All the items in the select box were selected before submitting, and this is the output that I get:

string
Array
A
r
r

This shows that what's being received is a string with the value "Array". I'm using IE6 (latest), and have also tested with Mozilla with the same results.
Any ideas?
THanks for any thoughts.

I've actually never seen a select menu created in that manner, so my guess is that it has something to do with that. It could just be that I'm behind on my HTML, in which case this post is most likely irrelevant. But if not, perhaps you could try creating it in the "traditional" way, such as the way this forum generates them. Below is the code taken from the "Rate this Thread:" select box.

<select name="rating">
 <option value="0">Select a rating (optional)</option>
 <option value="5">5 .. Best</option>
 <option value="4">4</option>
 <option value="3">3 .. Average</option>
 <option value="2">2</option>
 <option value="1">1 .. Worst</option>
</select>

To access the value, try using something like this:

<?php
echo $_POST['rating'];
?>

Hope this helps 😉

I found the source of the problem.
I was using the array_map() function to trim posted variables as such:

$_POST = array_map("trim", $_POST); 

that was causing the problem
I'm working on a function to work around this and still be able to use array_map functionality. I'll post it when I get it worked out.

This function seemed to work as an array_map alternative when posting form data with multiple item select boxes

// function allows array_map functionality with forms containing multiple item select boxes
function array_map_extended($function,$array){
 foreach($array as $key=>$val){
  if(gettype($array[$key]) != "array"){
   eval("\$array[\$key]=$function(\$array[\$key]);");
  }else{
 //this array variable is itself an array so apply the function to each element
   for($i=0;$i<count($array[$key]);$i++){
    eval("\$array[\$key][\$i]=$function(\$array[\$key][\$i]);");
   }
  }	
 }
 return $array;
}
$_POST = array_map_extended("trim", $_POST);
