I have been reading with attention your comments. I work on Omeka-s 1.4.0.
My wish is to limit fields in the public advanced search menu i.e to delete from the menu some properties event if they do exist on the administrative side.
I also wish to delete the field “search by class” which is useless in my case.
And last request, I wish to limit the public query to some item-sets.
I used the site settings in order to limit items sets search as described above.
I also ckick on the button restrict templates.
However when I go public view, I still have access to all items-sets on the fields " Search by items-sets".
I also red the link thttps://github.com/omeka/omeka-s/pull/1185 in order to adapt php.files.
However as my files doest not strictly correspond to those on Github and specially the variable " $isOptionUsed", doest not exist in the files, I have not been able to change the advanced search as we wanted to.
My last error message was : ( Zend\View\Exception\RuntimeException Zend\View\Renderer\PhpRenderer::render: Unable … ).
I thank you in advance if you can tell how I can proceed.
