Proposal of new image tag if_first_image inside txp:images
Some times I miss a tag like “txp:if_first_image” when using txp:images tag to retrieve a set of images.
Think in the typical product page in a e-commerce site for instance: You see a main photo and some thumbnails with other images about the product.
It will be nice to retrieve all images with a unique query, stiling the first different (bigger) than the others, with a code like this:
<txp:images auto_detect="article" wraptag="ul" break="">
<txp:if_first_image><li class="big"><txp:else/><li></txp:if_first_image>
<txp:image width="0" height="0"/>
</li>
</txp:images>Nowaday we can do this stuff but need a complex code, something like this:
<txp:adi_calc name="counter" value="1"/>
<txp:images auto_detect="article" wraptag="ul" break="">
<txp:if_variable name="counter" value="1">
<li class="big"><txp:else/><li></txp:if_variable>
<txp:image width="0" height="0"/>
</li>
<txp:adi_calc name="counter" add="1"/>
</txp:images>I suposse that “if_last_image” can be usseful for something too, but I really never needed it.

+1. And if_last_image, if_first/last_link, if_first/last_file :)

For the first and the following images you can also work with the limit and offset attributes.

I’ve opened a issue report 340 for this.

Re: Proposal of new image tag if_first_image inside txp:images
Jorge, there’s actually no need for a plugin. A structure like this inside your images tag helps detecting at least the first image:
<txp:if_variable name="first-image" value="1">
here goes code for image 2 and higher
<txp:else />
code for first image goes here
<txp:variable name="first-image" value="1" />
</txp:if_variable>In bad weather I never leave home without wet_plugout, smd_where_used and adi_form_links

Nice way uli, thanks! Anyway a if_first_image tag will be simpler for non programmers minds :-)

…if you know the limit. And the limit is not allways known.

Fine, in the future we will have the new tags. But now, the limit for the first is one (1).

Re: Proposal of new image tag if_first_image inside txp:images
r5063, r5064 and 5065 together introduce these missing list conditionals, adding total of 6 new tags:
- txp:if_first_image
- txp:if_last_image
- txp:if_first_link
- txp:if_last_link
- txp:if_first_file
- txp:if_first_file
Each of these tags can be used in their respective list contexts similarly to the existing _last/_first tags.
Images:
<txp:images wraptag="ul" break="li">
<txp:if_first_image>first</txp:if_first_image>
<txp:if_last_image>last</txp:if_last_image>
</txp:images>Links:
<txp:linklist wraptag="ul" break="li">
<txp:if_first_link>first</txp:if_first_link>
<txp:if_last_link>last</txp:if_last_link>
</txp:linklist>Files:
<txp:file_download_list wraptag="ul" break="li">
<txp:if_first_file>first</txp:if_first_file>
<txp:if_last_file>last</txp:if_last_file>
</txp:file_download_list>kees-b wrote:

You can’t believe how common typo that is for me. Daily pain.
