Hi,

i have 3 different out puts depending on if some TV are populated and wondered if its possible to do an else if. So basically i have:

TV-1
TV-2
TV3

IF TV-1 is empty do this,
ELSEIF TV-2 is empty do this
ELSE do this.

Any suggestions, i've tried nesting the filters, i've tried nesting the IF snippet and i've tried a combo of the two. But no luck.

I've also looked at the switch snippet which doesn't look like it will work in my case.

Thanks in advance

[[*tv1:empty=`[[*tv2:empty=`[[*tv3]]`]]`]]

Thanks splittingred for your help, the only problem i have here is i don't want to just render out just the tv value. So depending on which one is empty.

Probably better to use my actual situation as reading my first post i wasn't that clear.

I have 3 tvs.
TV1 contains a video path,
TV2 contains an image path
TV3 contains a description for the image

IF there's video(tv1) then render the html but if no video then check if a description(tv3) has been added. If there is a description then render the image html with the description html if not just render the image.

I was hoping just to nest some if calls. Oh also this is within a getResoure tpl. This is what i had tried.


[[+tv.videoPath:if=`[[+tv.videoPath]]`:eq=``:then=`[[+tv.hoverText:if=`[[+tv.hoverText]]`:eq=``:then=`MAGE no description`:else:=`IMAGE with description`]]`:else=`VIDEO`]]

it renders a video correctly, but images are all rendered as image with description.

Thanks

Ok i decided to see if i could write a snippet that could deal with this and it seems to be doing the trick.

I created a snippet called "areYouAVideo" with the following code

<?php
if ($videoSrc == '') {
	if ($hoverText == ''){
   		$output = "IMAGE";
	} else {
		$output = "HOVER";
	}
}
else {
   $output = "VIDEO";
}

return $output;
?>

Then used this call in my getResource template passing in the two TVs i want to check against if they had values. The call

[[areYouAVideo? &videoSrc=`[[+tv.videoPath]]` &hoverText=`[[+tv.hoverText]]` ]]

Not sure if this is the best way to do it, but it works.

In this case I would create a custom snippet with something like that:

<?php
if (!empty($videoPath)){
    return $videoOut;
}
if (!empty($hoverText)){
    return $hoverOut;
}
return $default;

and call it this way:

[[mysnippet?
&videoPath=`[[+tv.videoPath]]`
&hoverText =`[[+tv.hoverText]]`
&videoOut=`[[+tv.videoPath]]`
&hoverOut=`IMAGE with description`
&default=`IMAGE no description`
]]

Thanks Bruno, that works much better than mine. I was have some issues with placeholders displaying the same image for the else statement.

But no such problems with your snippet, thanks again.

Can we wake a sleeping thread?

I'm trying to create a nested output modifier like:

[[*tv1:notempty=`[[$DisplayChunkOne]]`:else=`[[*tv2:notempty=`[[$DisplayChunkTwo]]`:else=``]]`]]

Kindly look at this to see what's wrong cause right now nothing is displayed.

How about a snippet?

[[!DisplayChunk? &chunkOne=`SomeChunk` &chunkTwo=`SomeOtherChunk`]]

/* DisplayChunk snippet */

$chunk1 = $modx->getOption('chunkOne', $scriptProperties, 'No Chunk1');
$chunk2 = $modx->getOption('chunkTwo', $scriptProperties, 'No Chunk2');
$tv1 = $modx->resource->getTVValue('TV1');
$tv2 = $modx->resource->getTVValue('TV2');
$output='';

if (!empty($tv1)) {
    $output = $modx->getChunk($chunk1);
} elseif (!empty($tv2)) {
    $output = $modx->getChunk($chunk2);
}

return $output;

This assumes that they are always the same two TVs. If not the TV names or IDs could be sent as properties.

Yes the chunks and TVs will always be the same.

I've tried this but no output. The call [[!DisplayChunk? &chunkOne=`[[$Banner400H]]` &chunkTwo=`[[$Banner400H_wSlideshow]]`]] was placed in a template.

Since there are several TVs on the resource, I supplied the actual names of the TV: I think there is difficulty recognizing the TVs. [ed. note: ojchris last edited this post 9 years, 11 months ago.]

In the &chunkOne and &chunkTwo properties, you want the *name* of the chunk, not a tag for it:

[[!DisplayChunk? &chunkOne=`Banner400H` &chunkTwo=`Banner400H_wSlideshow`]]
