Hi,
I am new to this so please bear with me......
Have been trying to use the Galeryitem to form information in the way I want, for example: If I create a new TV and set the Input and Output to GalleryItem, when a call the TV in my chunk as such
Then this creates a img tag as follows:
<img src="/assets/components/gallery/connector.php?action=web/phpthumb&w=0&h=0&zc=0&far=&q=90&src=%2Fassets%2Fgallery%2F1%2F8.jpg" alt="Residential" title="" class="three-columb-img">
If I change the output to text I get the following:
{"gal_src":"/assets/gallery/1/8.jpg","gal_id":8,"gal_name":"Residential","gal_description":"Sketch Drawing Of A Residential Property","gal_image_width":292,"gal_image_height":200,"gal_orig_width":292,"gal_orig_height":200,"gal_album":"1","gal_watermark-text":"","gal_watermark-text-position":"BL","gal_other":"","gal_rotate":"0","gal_sizer":100,"gal_cropCoords":"","gal_cropTop":0,"gal_cropRight":0,"gal_cropBottom":0,"gal_cropLeft":0,"gal_class":"three-columb-img"}
Now I followed this post
https://forums.modx.com/thread/50588/tv-galleryitem-extract-image-path-description as I wanted to use certain elements from the GalleryItem but to do so it required I pass the id.
So my code ended up being something like this:
[[!GalleryItem? &id=`[[!getPicId? &imageTV=`[[*bannerImageOne]]`]]`]]
<img src="[[+galitem.image]]" alt="[[+galitem.name]]" title="[[+galitem.description]]" class="three-columb-img"/>
Where getPicId is a snippet as follows:
<?php
$obj=json_decode($imageTV);
return $obj->gal_id;
The problem I am getting with the above is that when I try to use different galitem items I don't get what I expect as following code shows:
description =[[+galitem.description]] </br>
name = [[+galitem.name]] </br>
filename =[[+galitem.filename]] </br>
description = [[+galitem.description]] </br>
mediatype = [[+galitem.[mediatype]] </br>
createdon = [[+galitem.createdon]] </br>
createdby = [[+galitem.createdby]] </br>
active = [[+galitem.active]] </br>
albums = [[+galitem.[albums]] </br>
tags = [[+galitem.tags]] </br>
url = [[+galitem.url]] </br>
Giving:
name = Residential
filename =8.jpg
description =
mediatype =
createdon = 2012-10-16 18:47:28
createdby = 1
active = 1
albums =
tags =
url =
Even though I have things like the description filled out it doesn't output, and what if I want the class? What If I just wanted the path as
/assets/gallery/1/8.jpg
instead of
/assets/components/gallery/connector.php?action=web/phpthumb&w=0&h=0&zc=0&far=&q=90&src=%2Fassets%2Fgallery%2F1%2F8.jpg
So the way I have done it is to create snippets for each bit of information I need i.e
To get the src I created getPicSrc:
$obj=json_decode($imageTV);
return $obj->gal_src;
So in the chunk, the following would give /assets/gallery/1/8.jpg
[[!getPicSrc? &imageTV=`[[*GalleryItemTV]]`]]
So now I can get the information I need to form the HTML in the way that I want and looking tider.
Now I'm sure their is probably a better way of doing it, instead of creating all these snippets and snippet calls?
Any ideas?
Thanks in advance.
