remove markup for TV when it's not used

If this question has been asked, please forgive me and please kindly point me to the thread - I couldn’t find anything from forum search.

I have a section called ’callout’ and the div wrap is always the same



I want to serve it as a wrapper for callout items that will be used in some pages, but not all.

I thought of creating a TV and placed in the template (the callout divs can go to chunk if necessary)


But if no items are placed in the callout TV, it will still show the
<div class="callout">
<div class="callout_btm">
</div>

in the source code. I don’t want that.

How can I have it removes if no item in the callout TV in a page?

Thanks!

hi,

very interesting question, i was asking myself how to achived this with modx ... (It’s very easy with smarty).

you could keep the whole wrapper in a chunk, then decided with PHx to show it only if the TV has value.

check this
http://wiki.modxcms.com/index.php/PHx#ifempty.3D.60other_value.60

I agree I would either use PHx



may work for you. More information about can be found at http://wiki.modxcms.com/index.php/PHx/CustomModifiers

good, thanks guys.

I though of the snippet solution, but didn’t found it very smart.
Phx solution is not very smart compared to the smarty syntax but is ok for the moment.

Another solution ?

do you look for a way to do it or to be a smartass?

just kidding
PHx seems very ’smart’ to me, at least very flexible I think.
what don’t u like in the phx way?

do you look for a way to do it or to be a smartass?

just kidding

;) I’m new to modx, and i think it’s important to focus on using it the best way.

Ain’t it better like that ? (smarty code). No big differences, ok. But to me it is, mostely because i used it a lot.

But that’s ok with PHx.

<?php
if (trim($output) != ’’) {
return $options;
}
?>

I hear what you say, it’s hard to adopt to a new system
but keep PHx in your bookmark, you’ll be surprised how many times it can help you do things you just have to have.
I use it in almost every modx site I’ve done. the best addon to modx after Ditto IMHO.

Thank you so much Taff and Sinbad.

___seb, you can use smarty when v0.97 comes out

Taff, just wanting to let you know, your code works beautifully.

I have this:

[+phx:if=`[*callout*]`:isnot=``:then=`<div class="callout">
<div class="callout_btm">
[*callout*]
</div>
</div>`:else=``+]

This new tricks makes me love Modx even more

I’m glad it works. As seb mentioned it may not be the tidiest solution but it works. If you want a something more smarty orientated then you should create a snippet that returns the output with the aid of http://modxcms.com/gettemplatevaroutput.html or one of the other template variable output.



Something like this would probably work (I haven’t tested it) Find out more about the API at http://wiki.modxcms.com/index.php/Category:API

As always with MODx you could spend all day finding different ways to skin a cat...I would go with the bowie knife solution (fastest) unless things started getting hard to track (which is possibly PHx’s downfall).

Good luck,
Taff
