[Cartoweb-users] Problem with Checkboxes

[Carolin Latze]

Hi,

hm.... I really forgot that :-/ Very stupid error, I know...

But I have another question regarding the checkboxes. The line

this->p1 = isset($request['prod1']) ? $request['prod1'] : '';

returns always an empty string, even if the checkbox has been checked.
Is there also problem with my syntax in cartoclient.tpl?

     {if $products_active|default:''}
     <p><b>Show all Companies for a special Product</b></p>
     Products:<br />
     <input type="checkbox" id="prod1"
name="Brotgetreide"/>Brotgetreide<br />
     <input type="checkbox" id="prod2" name="Butter"/>Butter<br />
     <input type="checkbox" id="prod3" name="Eier"/>Eier<br />
     <input type="checkbox" id="prod4" name="Milch"/>Milch<br />
     {/if}

I saw, that there are also checkboxes in the demoEdit sample project,
but I do not really understand it and was therefore not able to adapt it
to my needs.

Thanks in Advance
Carolin
