Hierarchical list of Checkboxes

What did you do? Can you show me your codes?

i put this code in the functions.php file but i am sure that this code is wrong.

add_filter('uwpqsf_tax_field_checkbox','custom_checkbox_output','',12);
function custom_checkbox_output($html,$type,$exc,$hide,$taxname,$taxlabel,$taxall,$opt,$c,$defaultclass,$formid,$divclass){

$eid = explode(",", $exc);//this is where you forgot to add,this will throw warning when debug mode is on

$args = array('hide_empty'=>$hide,'exclude'=>$eid, 'hierarchical' => true, 'parent' => 0 );//add new parameter to the parent argument.

$taxoargs = apply_filters('uwpqsf_taxonomy_arg',$args,$taxname,$formid);
$terms = get_terms($taxname,$taxoargs); $count = count($terms);

    if($type == 'checkbox'){
				if(!empty($taxall)){
				$checkall = (isset($_GET['taxo'][$c]['call']) && $_GET['taxo'][$c]['call'] == '1'  ) ? 'checked="checked"' : '';
				$html .= '<label><input type="checkbox" id="tchkb-'.$c.'" name="taxo['.$c.'][call]" class="chktaxoall" value="1" '.$checkall.'>'.$taxall.'</label>';
				}
                if ( $count > 0 ){
                    foreach ( $terms as $term ) {
                        $selected = $terms[0]->term_id;
                        $html .= '<label><input type="checkbox" id="tchkb-'.$c.'" name="taxo['.$c.'][term]" value="'.$term->slug.'">'.$term->name.'</label>';

                        $args = array(
                            'hide_empty'    => false,
                            'hierarchical'  => true,
                            'parent'        => $term->term_id
                        );
                        $childterms = get_terms($taxname, $args);

                        foreach ( $childterms as $childterm ) {
                                $selected = $childterms[0]->term_id;

                            $html .= "<label class='child'><input type='checkbox' id='tchkb-".$c."' name='taxo[".$c."][term]' value='".$childterm->slug."'".">" . $childterm->name . '</label>';

                        }}
                     }
                     $html .= '</div>';
				return  $html;
    }

}

What wrong with the code? It seem okay to me (I did not test it though).
Did you add the .child css (like margin-left: 5px) to make it see the different.

Actually! this code was for radios option and i customize it for checkboxes but it is showing now double entries of all the categories and when i click on search button, it doesn’t do anything ??

Try add $html = ''; before if($type == 'checkbox'). This is need to clear the $html placeholder from the default html output. Otherwise it will append your customized html output to the default one.

Thanx a lot. Yeah! you are right. now this is OK. It is showing all the checkboxes in hierarchy and not doubling html now BUT
when i click on SEARCH BUTTON, it does nothing ??
no searching, no action.

Well, if it works without this customization?
You have to check to see if there any js error. You can see it on the chrome/firefox/ie inspect element feature.

NO, there is no js error in the console.
this was not working before this customization.
Actually! before this customization, it was showing just double entries (checkboxes) of every category and it is OK now but does nothing after click on SEARCH BUTTON.
This is a VERY GOOD FEATURE and i request you to add this feature in the next version ??

It will not showing double entries by default.
It must have something mess with the plugin to make it shows double entries in default.

This maybe have something wrong with your theme or plugin conflict.
Unless I can look at theme or you backend files, i can’t really tell what is problem.

Add this JUST AFTER

if($type == 'checkbox'){ :

$html  = '<div class="'.$defaultclass.' '.$divclass.' togglecheck" id="tax-check-'.$c.'"><span  class="taxolabel-'.$c.'">'.$taxlabel.'</span >';
		$html .= '<input  type="hidden" name="taxo['.$c.'][name]" value="'.$taxname.'">';
		$html .= '<input  type="hidden" name="taxo['.$c.'][opt]" value="'.$opt.'">';

Thanks for this; the plugin with this modification will definitely come in handy for me!
