Tags filtering and gallery items count

Permalink Browser Info Environment February 04, 2019 at 1:46 PM

Hi shahroq,
I finally got my new website working using your great addon, if you remember i asked you some time ago about calling express data into custom template.
If you want to have a look here is the gallery url :http://mattpesquet.com/work/

My first question is about Tag filtering (i also use a custom file attribute to handle my own tags, and being able to set multiple tags to multiples files selection into file manager):
Is it possible to have tag filtering buttons filtering from all tags of each gallery item instead of the first tag of the list ?
I already tried to find a solution few month ago in controller.php and came across interesting lines of code, but i cant remember exactly which ones.
I guess it might be after :

@line 268  private function getGalleryInfoFileSet()
@line 272        //filter tags (buttons)
        $this->gallery->optionsObj->fTagsAr = explode(',',$this->gallery->optionsObj->fTags); //print_r($this->gallery->optionsObj->fTagsAr);die;

there is also that part :

@line 310            //get tags:
            $tags_attribute = Config::get('whale_grid_gallery.tags_attribute');
            if ($tags_attribute) {
                $fileTags = array();
                $gallery_tags = trim($fv->getAttribute($tags_attribute));
                if($gallery_tags) $tmp = explode("\n", str_replace(array("\r", ","), "\n", $gallery_tags));
            } else {
                $fileTags = $fv->getTagsList();
            }

@line 334:

//remove tags that are not in user selection:
            $tmp->tags = array_intersect($fileTags, $this->gallery->optionsObj->fTagsAr);
            $firsttag = array_shift($tmp->tags); //$firsttag is string, $tags is array of second to last tags
            $tmp->dataTags = "";
            if ($firsttag) $tmp->dataTags .= ' data-category="'.$firsttag.'"';
            if (count($tmp->tags)>0) $tmp->dataTags .= ' data-others="-'.implode("-", $tmp->tags).'-"';

Even if i know this part is to remove unwanted Tags (selected by user in edit window of the block), but it is where i see the $firsttag variable, that seems directly involved in the filtering working only on first Tag, and not the whole list of each item.

There is also further in controller.php a commented part of code :

@line 376            /*
            //tags
            if ($this->gallery->optionsObj->gFiltersEnable==1) {
                $tmp->tags = $fv->getTagsList();
                $tmp->tags_data = '';
                if (count($tmp->tags)>0){
                    //$tmp->tags_data = implode("", $tmp->tags);
                    foreach ($tmp->tags as $value) $tmp->tags_data .= $this->tagKeyGenerator($value)." ";
                }
            }
            */

The second question might be shorter, is it possible to display number of gallery items (just as it appears in block edit window : 'fileset-count') somewhere in my custom template ? what is the line of code to insert into some html tag please ?
Maybe if it can be seen in lightbox view ?

Best regards.

Hi Matt,
Sorry, I missed your ticket among other support requests.
1- Actually I didn't get what do you mean by "filtering from all tags of each gallery item instead of the first tag of the list". Can you elaborate on that part?
2- You can echo the number of files by:

echo count($gallery);
