Checkbox Reversed – select all pages where a checkbox is checked

[nurkka]

Hi all,

when using the following selector, ProcessWire finds all pages, not only those with the CheckboxReversed "checkbox_export" checked.

$ps = pages()->find('checkbox_export!=1, sort=id, include=hidden, status<' . Page::statusTrash);
foreach($ps as $p){
    var_dump($p->title);   
}

As a workaround I added the following condition:

$ps = pages()->find('checkbox_export!=1, sort=id, include=hidden, status<' . Page::statusTrash);
foreach($ps as $p){
    if ($p->hasField('checkbox_export')) var_dump($p->title);   
}

I wonder if there is any "native" selector technique, where you can check if a field exists on a page. Something like "has_field", but that does not exists. At least I found nothing in the docs.

Does anyone know the trick, if there is any?

There's no direct selector option, but you could get all templates that use the field first, then use those in the selector. Unless you use the field in repeaters or related types, fieldgroup name = template name.

$tpls = $fields->get('checkbox_export')->getFieldgroups()->implode('|', 'name');
$ps = pages()->find("template=$tpls, checkbox_export!=1, sort=id, include=hidden, status<" . Page::statusTrash);
