IF statement to hide MIGX call if empty?

Hi guys

I'm wondering if anyone knows how to wrap a MIGX call in an IF statement to hide it if it's empty?

For example I have this in my template:

<h2>Images</h2>      
[[$render-linked-gallery]]

And I'd like for the contents of [[$render-linked-gallery]] not to display at all if the client doesn't put any information into the related MIGX TV.

Any ideas? A big thanks in advance!

try

[[!getImageList? 
&............
&...........
&toPlaceholder=`myMigxPh`
]]

[[+myMigxPh:isnot=``:then=`
<h2>Images</h2>
[[+myMigxPh]]
`:else=``]]

-------------------------------

you can buy me a beer, if you like MIGX

Thanks Bruno

Fixed. Below is the code we used if it helps anyone. I put this in the chunk which formats the output (single-gallery-item) and called "render-linked-gallery" from my template.

[[*show-linked-galleries:ne=``:then=`
  <h2>Images</h2>
  [[getImageList?
    &tvname=`show-linked-galleries`
    &tpl=`single-gallery-item`
  ]]
`]]

Thanks for that Harmony, just want I needed for outputing several MIGX calls on one page for various tables, some of which were empty.

Thanks for sharing

You can also use the If snippet as well.

[[If? &subject=`[[*MIGxTV]]` &operator=`isempty` &then=`` &else=`<h2>Images</h2>
  [[getImageList?
    &tvname=`show-linked-galleries`
    &tpl=`single-gallery-item`
  ]]`]]

Hmmmm strange ... These solutions seem to have stopped working in MODX Revolution 2.2.12-pl (traditional). Result shows the else content regardless

 [[If? &subject=`[[*docs]]` &operator=`isempty` &then=`` &else=`<h2>Documents</h2>
  [[getImageList?
    &tvname=`docs`
    &tpl=`docs`
  ]]`]]

I have IF installed and docs is a migx TV and chunk.

The MIGX - TV does return an empty json - string in some situations '[]'

Use the toPlaceholder - property and check the result for empty, like that:

[[getImageList?
&toPlaceholder=`migx_output`
&otherproperties ..........
]]

[[+migx_output:!empty=`show this:[[+migx_output]]`]]

Thanks this works uncached

[[!getImageList? &tvname=`docs` &tpl=`docs` &toPlaceholder=`migx_output`]]

[[+migx_output:!empty=`show this:[[+migx_output]]`]]

Hi! Why isn't it possible to set a default Value in the Migx Template that is used in case there are no migx elements defined in the page?

I'm using migx right now for a slideshow and do not want to add different slides on all pages. I just wanted to use the default value property of my tv but unfortunately this is not working.
Or am i doing somthing wrong?
