php - How do i make an option panel with multiple option value's set? -


i have option panel in selected name id set in database. select multiple options , set more name id's one.

the code option panel this:

<select name="werknemer[]" data-placeholder="werknemers..." class="chzn-select" id="werknemer" tabindex="4">             <option value=""></option>                  <?if($werknemers !=null):foreach($werknemers $row):?>                     <option value='<?=$row->idwerknemer;?>'><?=$row->voornaam;?>&nbsp;(<?=$row->achternaam;?>)</option>                  <?endforeach;endif;?>             </select><br /></div></div>

this works perfect select multiple "idwerknemer" in 1 option value. how make work? have tried multiple style. doesnt post anything.

<select multiple>   <option value="volvo">volvo</option>   <option value="saab">saab</option>   <option value="opel">opel</option>   <option value="audi">audi</option> </select>

your code become

<select name="werknemer[]" multiple data-placeholder="werknemers..." class="chzn-select" id="werknemer" tabindex="4">             <option value=""></option>                  <?if($werknemers !=null):foreach($werknemers $row):?>                     <option value='<?=$row->idwerknemer;?>'><?=$row->voornaam;?>&nbsp;(<?=$row->achternaam;?>)</option>                  <?endforeach;endif;?>             </select>

keyword "multiple". see : http://www.w3schools.com/tags/att_select_multiple.asp

after selecting few values in selectoption, post form.

you $_post this:

array (     [werknemer] => array         (             [0] => 1             [1] => 2         )  )

see example of checkbox : multiple checkbox options on php form
