[RESOLVED] how to get the value of multiple dropdown?

[cmon1011]

i got this code @ file.php

    // Dropdown: Chemicals
    $chemicalsDropdown = getDropdown("CHEMICALS");
    while (list($key, $value) = each($chemicalsDropdown)) {
            if ($key == $_SESSION['enquiryPage']['wheel']['environment_chemicals']){
            $is_selected = "selected"; 
            } 
        else { $is_selected = ""; 
            }
        $template->process('CHEMICALS_LIST', array(
            'list_id'       => $key,
            'list_value'    => $value,
            'list_selected' => $is_selected
        )); 

and this code @ file.tpl

        <select name="environment_chemicals" multiple size="5" style="width: 300px;">
          <option value="0">[NO_CHEMICALS]</option>
          {section CHEMICALS_LIST}
          <option value="{list_id}" {list_selected}>{list_value}</option>
          {/section CHEMICALS_LIST}
        </select> 

i can select more than 1 chemical,
but after i press save button, the result will show only the last id that selected
how to get the other selected chemicals?
thx

Make the name of the SELECT element end in "[]", e.g.:

<select name='example[]'>

This will then populate an array of selected values in your $_POST array. For example, if you selected 3 items, then $_POST['example'][0] would contain the first, $_POST['example'][1] the second value, and $_POST['example'][2] the last value.
