Filter images by tags

[mentalhacker]

Hi,
In Phoca Gallery there are tags attached to images, but the tags are not clickable, there is no possibility for filtering images by tags.
Is there a solution for this problem?
Thank you.

Hi, there is no filtering in Phoca Gallery. For such purposes, maybe Phoca Cart can be used as it has advanced filtering methods:

Well, it's quite interesting because in fact THERE IS tag filtering option in Phoca Gallery. Everything is in the code but it was not fully implemented. If you compose this url:

index.php?option=com_phocagallery&view=category&tagid=7

it will filter the images by the tag with ID number 7. So the component handles the tag IDs, but there is no tag list view implemented.
In this file: administrator\components\com_phocagallery\libraries\phocagallery\tag\tag.php
the display of the tags can be modified in order to display clickable linked tags.

Line 125:
if ($tl == 0) {
$o .= $v->title;
} else if ($tl == 1) {
if ($v->link_ext != '') {
$o .= '<a href="'.$v->link_ext.'" '.$targetO.'>'.$v->title.'</a>';
} else {
$o .= $v->title;
}
The above code should be changed to this:
if ($tl == 0) {
// $o .= $v->title;
$link = 'index.php?option=com_phocagallery&view=category&id=tag&tagid='.(int)$v->id;
$targetA = $popupLink ? ['target' => '_parent'] : [];
$o .= JHtml::_('link', $link, $v->title, $targetA);
} else if ($tl == 1) {
if ($v->link_ext != '') {
$o .= '<a href="'.$v->link_ext.'" '.$targetO.'>'.$v->title.'</a>';
} else {
$o .= $v->title;
}

So the tags are now linked, and the filtering is OK, but there is no router, and no tag title on the tag list page (like a category title on a category page).
What do you think of this little modification? Is it worth implementing it in the code with router and title, and release it in the next version of Phoca Gallery?

Hi, I don't understand the code.

If it is set in parameters that tags should not have any link (tl == 0), why the code creates a link?

Tags are a part of category view, so they are linked in (tl == 2).

Ok, sorry, I overlooked this option in the parameters somehow. The tags can be linked with search outcome. That's great.
What is missing is the router and the tag title on the tag list page.
When a user clicks on a tag (in search outcome mode), a title on the tag list page should indicate the tag filtering, and a SEF url generated by the router would also be useful.
Any chance you could add these features to your code?

Hi, the link is generated by SEF:

Code: Select all

$link = PhocaGalleryRoute::getCategoryRoute($category->id, $category->alias);

or:

Code: Select all

$link = PhocaGalleryRoute::getCategoryRouteByTag($v->id);

See: administrator/components/com_phocagallery/libraries/phocagallery/path/route.php

method: getCategoryRouteByTag
