* Hi
* Great plugin!
I’m trying to display a tag cloud for pictures on a page using
the code [mla_tag_cloud taxonomy=”attachment_tag”]. I only want to show the custom
tags, not the wordpress tags. It does show a tag cloud with attachment_tag tags
only, but when i click on a tag, it goes to a 404 error page. For instance, it
loads [http://www.mysite.com/attachment_tag/tag-name](http://www.mysite.com/attachment_tag/tag-name)
but shows a “not found” error. Same thing with attachment_category. I couldn’t
find anything in the settings to fix the issue. Thanks for your help!

* Thanks for the good words and for your question, which has come up before. The
standard “taxonomy archive” pages provided by WordPress explicitly filter out
Media Library items, which can be frustrating. Here is an earlier topic that
goes into more details and provides several possible solutions:
* [‘Page not found’ when clicking Att. Tag in WP default Tag Cloud widget?](https://wordpress.org/support/topic/page-not-found-when-clicking-att-tag-in-wp-default-tag-cloud-widget)
* The tag cloud is only one way to select terms and display items that are assigned
to them. Here is another topic that might give you additional ideas:
* [Shortcode](https://wordpress.org/support/topic/shortcode-456/)
* If the above topics don’t give you what you need, post an update here with any
additional information you can and I will give you more specific guidance. Thanks
for your interest in the plugin.

* Thanks David for the quick answer. It is very helpful.
I added a gallery page
called “/gal/” and changed my codes :
* **Tag page**
[mla_tag_cloud taxonomy=attachment_tag number=0 limit=10 mla_link_href
=”/gal/?current_id={+term_id+}”]
* **Gallery page (/gal)**
[mla_gallery post_mime_type=all tax_query=”array ( 0
=> array ( ‘taxonomy’ => ‘attachment_tag’, ‘field’ => ‘id’, ‘terms’ => array({
+request:current_id+} ), ‘include_children’ => false ) )” mla_caption=”{+title
+}” columns=1 posts_per_page=5 size=large link=none]
* It seems to work pretty well now. I just have two more questions 🙂
* -Is it possible to show the value of a custom field in the output of the gallery?
Below the caption of the image, I’d like to show the value of a specific custom
field. Is it possible ? If so, is it possible to test if it exists before the
echo ?
* -Second question, is it possible to link to the full size image using something
like lightbox ?
* Thanks again, your plugin is really awesome!

* Thanks for your update with the good news regarding your progress. You can show
custom fields and a number of other data values in the `mla_caption` field with
Field-level Substitution Parameters and Content Templates (see the Settings/Media
Library Assistant Documentation tab). For example, if your custom field is called“
My Custom Field”, you can code something like:
* ```
mla_caption="{+title+}{+template:(
{+custom:My Custom Field+})+}"
```
* The parentheses around the template value will suppress the output if an item
does not have a value for the custom field.

* [Fixed height and Auto width on images displayed via mla_gallery](https://wordpress.org/support/topic/fixed-height-and-auto-width-on-images-displayed-via-mla_gallery)
* You can find more information about combining MLA with lightbox plugins in the“
Support for Other Gallery-generating Shortcodes” and “Support for the ‘Photonic
Gallery for Flickr, Picasa, SmugMug, 500px and Instagram’ Plugin” sections of
the Documentation tab.
* This earlier topic has links to a couple of lightbox plugins that work with MLA:
* [Not working after update](https://wordpress.org/support/topic/not-working-after-update-13/#post-6237119)
* There are many lightbox plugins; some work with MLA, some don’t. If you find
a lightbox you like and need specific guidance, start a new support topic here
and I will give any help I can.

* Thank you very much. I’m almost there now 🙂
Just a little extra question. When
I use HTML entities, it just outputs exactly what i entered. I cannot output
a line break. If I use
, it outputs the word
instead of showing a line
break. If I use
, it outputs

* Another thing 🙂 Sorry I’m trying to find a search form specific to this forum
but I can’t, I can only search the whole wordpress site apparently.
* I was wondering if i can use php functions in shortcodes. I have a custom field
mapped to the creation date of an image. i’d like to output under each image
of a gallery the creation date in a french format, like “date_format({custom:
Date_Creation_Image}, ‘d-m-Y’)”.
Is it possible ?
* Thanks

* Thanks for your updates – looks like you’re making good progress.
* You wrote “**_When I use HTML entities, it just outputs exactly what I entered._**”
The most common reason for that is entering the parameters in the editor’s Visual
tab instead of the Text tab. You **must** use the Text tab to prevent the editor
from “improving” the text you enter.
* You wrote “**_I’d like to output under each image of a gallery the creation date
in a french format …_**” Entering PHP code is not directly supported, but MLA
provides some date conversion formats that should work. You can find them in
the “Field-level option/format values” section of the Settings/Media Library
Assistant Documentation tab. For the example you give you can code something
like:
* ```
mla_caption="{+custom:Date_Creation_Image,date('d-m-Y')+}"
```
* The date and timestamp formats use the PHP functions, so they should handle any
of the formatting you need. If you need more complex logic you can always use
the hooks provided by the `[mla_gallery]` shortcode and write as much PHP code
as you need.

* Regarding the ever-frustrating limitation of the search function, here’s a tip
form an earlier topic:
* [Many Warnings](https://wordpress.org/support/topic/many-warnings-1/#post-7188095)
* So, if you want to search the MLA forum topics for “lightbox” you go to Google
and enter:
* > search-phrase “media library assistant” site:wordpress.org/support/topic/
> lightbox
* How’s that for user-friendly?

editor problem!! 🙂 Impressive plugin and great support.

* Hello, David!
Thank you for your powerful plug-in, but its power seems too much
for such an unexperienced WP user like me) – I have strange “404 not found” tag
cloud problem and can not resolve it – your kind suggestions and supportive links
above does not help.
* When i use the code (mbruxelle’s working example: [mla_tag_cloud taxonomy=attachment_tag
number=0 limit=10 mla_link_href=”/gal/?current_id={+term_id+}”]), i see a list
of tags on resulting page. On tag mouse over i see “20 tags”, Mozilla shows “
www.domenname/”gal/?current_id=36″” at the left bottom. When i click any tag
i see “Not Found
The requested URL /â€/gal/ was not found on this server.”
Note strange prefix “— – it looks like a bug.
* When i use another code example from MLA support:
[mla_tag_cloud] taxonomy=attachment_tag
mla_link_href=”{+page_url+}?current_id={+term_id+}&mla_cloud_current={+request:
mla_cloud_current+}” [/mla_tag_cloud] [mla_gallery] attachment_tag=”{+template:({
+request:term_slug+}|a-bad-term)+}” [/mla_gallery] I also see a list of tags
on resulting page. On tag mouse over i see “20 tags”, Mozilla shows “www.domenname/?
page_id=174?current_id=36&mla_cloud_current=” link at the left bottom. When i
click any tag on the page, it reloads but instead of gallery i see the same list
of tags.
* I tried some other working examples from solved topics of MLA support – no success.
I changed themes several times, even use 2012 with your child theme and three
custom PHPs you suggested – no result. Dis-activating all plug-ins except MLA
does not help too.
* I gave up at last and need your help.

* Thanks for your question and for your patience in awaiting my reply (I am traveling
and have limited Internet access).
* Thanks as well for including the complete text of your shortcode; very helpful.
* It looks like your problem is caused by “smart quotes”/”curly quotes” in the
shortcode text; often from copy/paste of a support topic. Be sure you use the“
Text” tab, not the “Visual” tab in the WordPress editor and replace all of the
curly-quote marks with plain-text quote marks. That’s why Mozilla shows the quotes
before the “www.” and the strange prefix in your URL.
* I can’t test your shortcode while I am on the road, but if you carefully remove
all the odd characters and quotes you should have better results. If that does
not solve your problem it would be best to open a new support topic of your own
so I can give you more specific help. Thanks for your interest in the plugin.
