Simple array question

[ajs83]

I'm using the following code to grab the value of a dropdown box called "category"

if($_POST){
foreach ( $category as $value ) {
echo "$value<br>";
}

How do I also grab the option id associated with the row?

<option id="$id" value="$cid">$name</option>

You mean this?

<select name=""> 
<?php 
foreach ($category as $id => $value) : 
 if ($categorySelected == $value) 
  echo "<option value=\"$id\" selected>$value</option>"; 
 else 
  echo "<option value=\"$id\">$value</option>"; 
endforeach; 
?> 
</select> 

if so $category is gathered in this way (using your own sql queries of course):

<?php 
$categorySelected = 'a selected category'; 
$sql->query("SELECT id,value FROM aTable"); 
while ($sql->nextRow()) 
{ 
 $category[$sql->row['id']] = $sql->row['value']; 
} 
?> 

please tell me if this answer your question.--

I'm posting the form values to the script above, what I need it to do is also pick up and echo the option id as well.

Currently Using

<select size="1" name="category[]">
while (blah){
<option id="$id" value="$cid">$name</option>
}
</select>

Which posts to to

if($_POST){
foreach ( $category as $value ) {
echo "$value<br>";
}

It works fine for the option value, but I also need the option id.

Let me clear this:
you mean pass 2 values ($id and $value) throught a select tag?

if so the a very fast (and dirty) solution is something like this:

<select size="1" name="category">  
while (blah) {  
<option value="$cid=$id">$name</option>  
}  
</select> 

<?php 
if ($_POST) 
{ 
 $var = explode('=', $_POST['category']); 
 echo $var[0]; // value option 
 echo $var[1]; // id option 
?> 

what do you think?

[ajs83]

Yes, I do want to pass both values, but i need to do so in the form of an array since there are over 100 different versions of that select dropdown box.

All contain the same category[] name, it's just I don't know how to post two values from the array.

[chrisjoha]

That's not possible. Consider using something like this:

<select size="1" name="category[]">
while (blah){
<option id="$id" value="$cid::$id">$name</option>
}
</select>

Which posts to to

if($_POST){
foreach ($_POST['category'] as $value ) {
  list($cid, $id) = explode('::', $value);
  print 'CID: ' . $cid . ', ID: ' . $id . '<br />';
}
