Name the select box as an array. For example:
<select multiple name="colors[]" size="4">
<option value="red">Red</option>
<option value="blue">Red</option>
<option value="green">Red</option>
<option value="yellow">Red</option>
</select>
Then when you submit the form, you will have an array $colors. Note that
the array will not be of size four necessarily: it will be of the size of
the number of options selected. If they select none of the options then it
will be of sizeof 0. So you can check by looping through. Each value of
the array is the value of one of the options that was selected.
if (sizeof($colors) > 0) {
for ($idx = 0; $idx < sizeof($colors); $idx++) {
// do stuff with the values of $colors[$idx].
}
}
else {
// no options were selected.
}
