Is it possible to use parameters within a placeholder

Hi there,

I'm using a migx addon (to manage several videos in a same resource) with a getImageList snippet:



then I use placeholders and place any video in the [[*content]]:

[[+video.1]]
[[+video.2]] etc

Everything works fine until now. My question: Is it possible to pass a parameter in the placeholder like:

and retrieve the «size» parameter in my «content.video.tpl» chunk?


Or maybe:

but I don't know how to start with this «size» snippet


I would like to avoid using the verbose syntax
[[newSnippetVideo? &video=`[[+video.1]]` &size=`200` ]]
the editors might be frightened

Thanks for your help!
Sylvain

I wouldn't think so; placeholders are simply ...um, placeholders to mark a spot where the snippet will insert parts of its output, whether the output has been loaded into the $modx->placeholders array (object?) or not. They don't get processed, so properties wouldn't mean anything. Unless, of course, I'm missing something, which is quite possible

Thank you for your response Susan, I'll find another solution

Well, keep an eye on this thread, I may be wrong, and hopefully if I am somebody who knows better will post.

Actually, have you considered using Property Sets? You put all the properties in the Property Set, then just have

That's a good way to simplify the syntax, thanks for the idea

saerni, were you able to come up with a good solution to this? I want to do the EXACT same thing with a MIGX TV (when I saw your post I was pleased to see that someone had the exact same idea I had).

When I thought through the issue on my own, it almost seemed like it would work, but clearly it doesn't. Did you come up with a solution that works within the normal MODX parameters (ie, not a hack or some weird syntax that's counterintuitive.) If Susan's solution helped you, can you describe how you implemented it?

Best,
Mike

Mi Mike,

I read your post, dived a last time in this problem, and I found right now a simple solution:

I use also a MIGX TV, I simply added a new «width» parameter in the MIGX table.

Hope it helps!
Regards,
Sylvain

sylvain, thanks for your reply. That solution wouldn't work for my particular needs, because the property I want to pass is a class that i want to manually assign depending upon where in the content the image is. I want to assign it outside of the MIGX table.

I ended up taking a different approach, which was to create a container chunk (insertImage) and pass both the [[+MIGX.1]] placeholder AND my class as properties of that chunk. The tag is a little more convoluted than I wanted for use in my blog content, but it's the best solution I could come up with:

[[!getImageList?
&tvname=`resourcealbum`
&tpl=`resourceimage.tpl`
&toSeparatePlaceholders=`MIGX`
&placeholdersKeyField=`idx`
]]

resourceimage.tpl:
src="[[+image]]" alt="[[+title]]"

Container chunk (insertImage):
<img [[+ii.image]] class="[[+ii.class]]" />

Calls I use in my blog post content field to render each image where I want it:
[[$insertImage? &ii.image=`[[+MIGX.1]]` &ii.class=`full`]]
[[$insertImage? &ii.image=`[[+MIGX.2]]` &ii.class=`normal`]]
[[$insertImage? &ii.image=`[[+MIGX.3]]` &ii.class=`right`]]

etc
