So I use PHx all the time for if/then statements, but not sure how to accomplish this: when I have 3 T.V.’s that are empty on a given document, I need a certain output. If any 1 of the T.V.’s is not empty, then another output.
For example, I would like to be able to say something along the lines of:
- if [*tv1*], [*tv2*], [*tv3*] are all empty, then = x, but if one of the T.V.’s has a value, then = y
Hope that makes sense. Generally as I mentioned, I use PHx for all my conditional statements, but I’m not finding an example for this scenario.
Thanks!

I think this can be done with the "and" and "or" modifiers in PHX, but really, you’d be much better off with one fairly simple snippet. It would be *much* faster and more efficient.
Something like this (just put the snippet call where you want the output):
(untested)
[!MySnippet? &tv1 = `[*templateVariable1*]` &tv2 = `[*templateVariable2*]` &tv3 = `[*templateVariable3*]` !]
And in the snippet:
<?php
$empty = "Output when they are empty";
$notEmpty = "Output when one is not empty";
$output = $notEmpty;
$tvs = $tv1 . $tv2 . $tv3;
$tvs = strip($tvs);
if (empty($tvs) ) { /* all are empty */
$output = $empty;
}
You could also put the two different output sections in chunks:
<?php
$empty = "name_of_empty_chunk";
$notEmpty = "name_of_not_empty_chunk";
$output = $notEmpty;
$tvs = $tv1 . $tv2 . $tv3;
$tvs = strip($tvs);
if (empty($tvs)) { /* all are empty */
$output = $empty;
}
return $modx->getChunk($output);
?>
I made this snippet recently and it sounds like it is close to what you are asking. I use it in the content section of the template to format the output depending on if the tv’s have content or not.
<?php
/* Content_Formatter
[!Content_Formatter!]
*/
$thisid = $modx->documentIdentifier;
$output ='';
$tvcontentT = $modx->getTemplateVarOutput(array("R_Column_TContent"), $docid=$thisid);
$tvcontentM = $modx->getTemplateVarOutput(array("R_Column_MContent"), $docid=$thisid);
$tvcontentB = $modx->getTemplateVarOutput(array("R_Column_BContent"), $docid=$thisid);
if($tvcontentT['R_Column_TContent'] =='' && $tvcontentM['R_Column_MContent'] =='' && $tvcontentB['R_Column_BContent'] ==''){
// if all three tv's are empty, output this:
$output .='<h2>[*longtitle*]</h2>[*content*]
[*C_Column_BContent*]';
}else{
// if any of the tv's have content, then output this:
$output .='<div style="float:left; width:500px;">
<h2>[*longtitle*]</h2>[*content*]
[*C_Column_BContent*]
</div>
<div style="float:right; width:200px;">
[*R_Column_TContent*]
[*R_Column_MContent*]
[*R_Column_BContent*]
</div>
<div style="clear:both;"></div>';
}
return $output;
?>
Hope it helps send you in the right direction at least

Thanks for all your replies.
BobRay, I tried your approach, but I was getting an error message. Unfortunately, I absolutely stink at PHP and therefore can’t debug when there’s a problem, so I played around with PHx some and came up with this that worked:
[+phx:if=`[*pdf_doc_1*]`:is=``:and:if=`[*pdf_doc_2*]`:is=``:and:if=`[*pdf_doc_3*]`:is=``:then=``:else=`{{coupons}}`+]
I have never tried the and:if statement with PHx...worked like a charm...thanks BobRay for pointing me in the right direction.

I’m glad you got it working.
BTW, If you want to try the snippet approach again, let me know what the error message was and I’ll try to figure out what went wrong.
I did notice a formatting error in my message that caused an error in the snippet call (fixed now).

Unfortunately the site is live now so I don’t want to reinstate the snippet that was taking the site down, but the whole screen went white with 2 lines of error messages, so something pretty significant I guess

That could be just a typo in the PHP and the site was probably not actually down, but I can understand not wanting to mess with something that’s working.
