retrieving multi valued select 'value'

Frage
Can anyone tell me how to get the 'value' of selected items from a multivalued select?
I have the following:
<select id="category" name="category[]" multiple="multiple">';
/* Select categories */
[...]
<option value"' . $row->id . '">' . $row->name . '</option>';
which would return:
<option value"1">itemName1</option>
Why is the code below giving me the selected text and not their values? What's wrong here?
$category = $_POST['category'];
if (count($category) > 0){
foreach ($category as $key => $value) {
echo $value . "<br>\n";
}
}
This is returning itemName1
and I need the actual value (1)
Thank you
Lösung
Your HTML is invalid. You have:
<option value"1">itemName1</option>
while it should be:
<option value="1">itemName1</option>

mulple select will return a query like this (name = name and values = int)
name=1&name=4&name=99
so it return the selected values the array would look like:
array(
name => array(
[0] => 1
[1] => 4
[2] => 99
)
)
ps if you fix the HTML error, you will most likely get a valid result
