[Solved] Phx: Checking empty TVs

I’ve been trying to use Phx in order to show/not show pre/after-content of TV output. Like so -

[+phx:if=`slideshow-image-1`:is=``:then=``:else=`<li><img src="./assets[*slideshow-image-1*]" width="958" height="270" /></li>`+]

Also tried

[+slideshow-image-1:isnotempty:then=`<li><img src="./assets[*slideshow-image-1*]" width="958" height="270" /></li>`+]

Nothing’s displayed. I’m sure I have Phx running since I’m using Character Limit on some other pages. What am I missing? Or should I approach this in another way?
I couldn’t find an easy method of including X images in a post so I created a couple of TVs, that’s why it looks like this.

Don’t you miss a slash between assets and [*slideshow-image-1*] ?

/assets/[*slideshow-image-1*]... Not sure but it could be that...

Cheers

No the reference is correct. I’ve tried with simply showing text messages just to confirm it’s not the image source.

You’d better try with [+phx:if=`[*slideshow-image-1*]`:is=``:then=``:else=`your output`+] to indicate that you want to check the TV

Good luck

Oh! Well, I tried your suggestion and it still doesn’t work... this is driving me nuts!

Here’s what I’m currently using:

[+phx:if=`[*slideshow-image-1*]`:is=``:then=``:else=`<img src="./assets[*home-slideshow-1*]" width="958" height="270" />`+]

Tried outputting text if empty just to be sure. Still nothing. And there IS content in the TV.

Try using ifempty instead of =.

You could do it as a snippet :

<?php
$tv = $modx->getTemplateVarOutput(true, $modx->documentIdentifier);
$field = $tv['home-slideshow-1'];
if(!empty($field)){
$output = '<img src="./assets'.$field.'" width="958" height="270" />';
}
return $output;
?>

The only method that worked was the snippet version. I guess what you’re suggesting is that I make a genereal snippet that checks for empty TVs and not one for each wink

That would be a good thing to use throughout the page. It’s just that I’m very new to snippets, not sure how I could check each TV? By a parameter (&tvHasContents=`yourTV`) perhaps?

Solved. I installed PHx (which is weird considering I have other PHx functions running through the core installation) then tried [+phx:if=`[*slideshow-image-1*]`:is=``:then=``:else=`<img src="./assets[*slideshow-image-1*]" width="958" height="270" />`+]

Ditto and some other snippets come with Phx integrated in them, but to globally access PHx it has to be installed.
