Hi all,

I have a question about the TV - input type: listbox(single-select) (input option values). Inside this input option values, I have: Amsterdam||London||NewYork||Brussel||Paris. This will create a listbox in the back-end. Now I want to know or it is possible to have this on the front-end. Do I need a snippet or is there any plugin for this.

Thanks for your time.

<select name="filter_name">
[[!getTvOptions? &tpl=`filterSelectOption` &tvname=`selectTV` &name=`filter_name`]]
</select>

snippet getTvOptions:

//[[getTvOptions? &tpl=`myChunk` &tvname=`myTv` &name=`cb1`]]
 
$tv = $modx->getObject('modTemplateVar',array('name'=>$tvname));
$options = explode('||',$tv->get('elements'));
 
foreach ($options as $option){
    $opt = explode ('==',$option);
    $ph['value'] = count($opt)>1 ? $opt[1]: $opt[0];
    $ph['text'] = $opt[0];
    $ph['name'] = !empty($asArray) ? $name.'[]' : $name;
    $ph['checked'] = ''; 
    $ph['selected'] = '';
    
    if ((is_array($_REQUEST[$name]) && in_array($ph['value'],$_REQUEST[$name])) || $_REQUEST[$name] == $ph['value']){

        $ph['checked'] = 'checked="checked"'; 
        $ph['selected'] = 'selected="selected"';      
       
    }

    $output .= $modx->getChunk($tpl,$ph);
}
 
return $output;

chunk for normal use:

<option value="[[+value]]" [[+selected]]>[[+text]]</option>

for use with formit:

<option value="[[+value]]" [[!+fi.[[+name]]:FormItIsSelected=`[[+value]]`]]>[[+text]]</option>

Thanks for your kindly help Bruno, it works like a charm.

[!getTvOptions? &tpl=`filterSelectOption` &tvname=`selectTV` &name=`filter_name`]]
must be 
[[!getTvOptions? &tpl=`filterSelectOption` &tvname=`selectTV` &name=`filter_name`]]

One [ was missing,

easy, and worked


    //if ((is_array($_REQUEST[$name]) && in_array($ph['value'],$_REQUEST[$name])) || $_REQUEST[$name] == $ph['value'])
    
    if ($ph['name']==$ph['value'])
    {
        $ph['checked'] = 'checked="checked"'; 
        $ph['selected'] = 'selected="selected"';      
    }
 
    $output .= $modx->getChunk($tpl,$ph);
}
  
return $output;
