Uncached Snippet Calls in Fields not working correctly with properties

devumapp · March 6, 2017, 3:07pm

It seems to be a ModX Bug, but I wanted to mention it here as well, since it was coming up when using Content Blocks. So far, I haven’t found a solution for this, but maybe someone already knows a possible workaround.

ModX has a problem with uncached snippet calls in nested environments, when a property is using an equal sign in its input string. The whole output turns blank in that case.

For example: I cannot get this formit call to work, neither using the call inside the cb fields template tab directly, nor in a chunk I am calling from there:

[[!FormIt?
   &hooks=`FormItSaveForm,redirect`
   &redirectTo=`1`
   &fieldnames=`fieldname==newfieldname, anotherone==anothernewname`
]]

There is already a github issue:

### Summary Weird effects with nested items. Although the use cases are a bit w…eird and probably give wrong results, it should not give broken results like it does now. ### Step to reproduce I simplified the cases a bit. **Case A** Create a chunk called 'rowChunk' with the following content: ``` [[+rows]] ``` Create a chunk called 'equalChunk' with the following content: ``` [[!++site_url:notempty=`<p class="success">[[!++site_url]]</p>`]] ``` Put this in your template: ``` [[$rowChunk? &rows=`[[$equalChunk]]` ]] ``` **Case B** Create a chunk called 'rowChunk' with the following content: ``` [[+rows]] ``` Create a chunk called 'longChunk' with the following content: ``` [[!longSnippet? &value=`Lorem ipsum dolor sit amet, consectetuer adipiscing elit.

Vestibulum ante ipsum primis in faucibus orci luctus et ultrices posuere cubilia Curae; Sed aliquam`]] ``` Create a snippet called 'longSnippet' with the following content: ``` <?php $value = $modx->getOption('value', $scriptProperties, ''); return $value; ``` Put this in your template: ``` [[$rowChunk? &rows=`[[$longChunk]]` ]] ``` ### Observed behavior **Case A** It shows no output at all, but if I remove 'class="success"' it works. Making the !$rowChunk or the !$equalChunk uncached also works. But the case as described breaks. **Case B** It shows the following: ``` Sed aliquam`]]` ``` So not the full string as given. Making the !$rowChunk or the !$longChunk uncached works. But the case as described breaks. ### Expected behavior **Case A** Showing the Site URL. **Case B** Show the given string. ### Environment - MODX: Tried multiple versions (2.5.0, 2.5.1, 2.5.2, 2.5.4). - Nginx - Mysql: Ver 15.1 Distrib 10.0.28-MariaDB I tried multiple encodings and collations.

any ideas?

best regards

If that is copy-pasted directly from your MODX installation, you’re missing a ` in the &redirectTo line.

it seems that got lost while copying it. I edit my post. thanks for the hint!
