Hi,

I have a div in a template and I want to show this div when the page id is 1 & 95.

Currently I am doing something like this but it is not working:

				[[*id:is=`1`,`95`:then=``:else=`
					<div class="breadcrumb"> [[BreadCrumb]] </div>
				`]]

This is not working. Sorry but I am new to modx.

Not sure if it will work but try:

[[*id:is=`1,95`:then=``:else=`
    <div class="breadcrumb"> [[BreadCrumb]] </div>
`]]

How about

[[[[*id:is=`1`:or=`95`:then=`$breadcrumb`]]]]

With a breadcrumb chunk

<div class=breadcrumb>[[Breadcrumb]]</div>

This is calling a snippet called 'BreadCrumb'.

[[*id:is=`1`:or=`95`:then=``:else=`
    <div class="breadcrumb"> [[BreadCrumb]] </div>
`]]

Do you have a snippet with that exact name? If you're trying to show a Chunk or Template Variable with that name, you'll have to tell us what version of MODX you're using so we can advise you.

There is a reason why dinocorn has that particular structure; i.e. the doubled-up tags around the conditional, and no tags inside. The way yours is, MODx will see the snippet and process the snippet before the condition is even tested. So whether it's to be displayed or not, the snippet is still processed.

By having the output of the conditional be just the snippet (or chunk) name, so that the tags aren't inside the conditional, what you get is an empty set of tags if the condition is false, and the set of tags with the snippet (or chunk) name if it's true.

[[[[id:is=`1`:or=`95`:then=``:else=`Breadcrumb`]]]]

will produce [[]] if either of the first two conditions are true, or [[Breadcrumb]] if they are both false. MODx simply removes the empty tags.

This way the snippet is only run if the resource is not #1 or #95.

thanks to all for your help. However I is still not working.

In the template I changed the code to ---> [[[[*id:is=`1`:or=`95`:then=`$breadcrumb`]]]]

Then i created a chunk named breadcrumb and in this chunk i included the following code ---> <div class="breadcrumb">[[Breadcrumb]]</div>

I am using modx revolution and this is not working. The breadcrumbs has vanished from all of the pages.

Issue has been fixed. We were missing the shocked

r:is in the code

[[*id:is=`1`:or:is=`95`:then=``:else=`
    <div class="breadcrumb"> [[BreadCrumb]] </div>
`]]

Thanks to all for your help

Try this in the chunk (unless you've changed the name of the Breadcrumbs snippet):

<div class="breadcrumb">[[Breadcrumbs]]</div>

You might have to call the snippet uncached to get the right output:

<div class="breadcrumb">[[!Breadcrumbs]]</div>

FYI, I would do it this way (with a custom snippet) to speed things up:

[[!MyBreadCrumbs]]

/* MyBreadCrumbs snippet */

$id = $modx->resource->get('id');

if ( ($id == 1) || ($id == 95) ) {
   return $modx->runSnippet('Breadcrumbs');
} else {
   return '';
}
