TVs inside snippet call - possible?

    I’ve been trying for the past hour to make this work:
    [[PhotoThumbnail?photo=`[*myimagefield*]`]]

    where myimagefiled is a template variable I’ve defined.

    The problem is that the snippet gets passed the text [*myimagefield*] and not the contents of this TV. Is it possible to capture the contents?

    This is using MODx 0.9.5 rev 2106, on Apache 2.0.X with MySQL. Everything else works fine.

    Thanks!

      It definitely is. I am using

      [[getVeranDateString? &anfang=[+veranStart+] &ende=[+veranEnde+]]]


      within a chunk and that works very fine. I do not use backticks as you can see, but I think that I first had them and that worked too. Maybe you misspelled some thing? it’s all case sensitive.

        Hmm, I wonder if the chunk is the secret? The spelling isn’t wrong and i’ve tried both [*...*] and [+...+], removing the backticks and still nothing happens... it just passes the whole [*...*] string through to the snippet.

          Right now there is a very specific order of parsing going on in the core. This means you have to respect that order when processing occurs. See the wiki for an article which describes this order of execution.

          As part of the rewrite for 0.9.7, the new core parser respects true source order and nested tags, regardless of the types of tags being encountered. In other words, this will be possible very soon, but for now, you’ll have to find an alternate approach.

            Thanks, I’d studied that article earlier today, and from it gathered I shouldn’t have any problems, as rule 18 is assignment of TV’s, and rule 21 is the parsing of snippets back into the template.

            Sadly this system is impossible to upgrade, as it’s been locked down by the IT department, and I am not allowed access to the PHP files! Which makes extending the site somewhat more ’fun’ than it should be!

              Did you try this?

              [!PhotoThumbnail?photo=`[*myimagefield*]`!]

                Ah, rule 18 is incorrect - rule 22 (the rule after Snippets) appears to be the substitution of template variables.

                Is there *any* way round this problem? Basically I’ve written a snippet to automatically thumbnail images, cache them, and deliver back the cached image. To do this I need to be able to pass in the image name to the snippet. Is there any way I can do this with 0.9.5? I’m hoping there’s an alternative approach that’s eluding me...

                  The uncached approach I posted below should work fine...

                    Did you try this?

                    [!PhotoThumbnail?photo=`[*myimagefield*]`!]

                    Interesting... if I try
                    [!PhotoThumbnail?photo=`[*myimagefield*]`!]
                    then the page calling the snippet won’t load.

                    If I try
                    [!PhotoThumbnail? &photo=`[*myimagefield*]`!]
                    then the page loads, and the value of $photo is NULL (no, not even an empty string).

                    The value of [*myimagefield*] is something like 
                    http://218.15.27.6/path/to/Filename With Spaces(1).jpg
                    - whether that makes any difference.
