Reusing Content

I have 2 Chunks (call them A and B). Each Chunk is used in a different Resource/Page (call them 1 and 2). Each Chunk includes several different TVs but both share two common TVs. I want to take the rendered (common) TV content of Page 1 and insert it into Page 2. I've been reading the docs but can't find a way to do it.

Thanks

Todd

I should think that you should be able to use @EVAL ... and use code to fetch the value for Page 1.

@EVAL $page = $modx->getObject('modResource', 1);
return $page->getTVValue('myTV');

Is there really a need for this to be a TV? Could it not be a snippet that fetches the value for the TV in Page 1? @EVAL in a TV is not really the best way to get specified element content.

I'm pretty new to MODX so it's very possible that a TV isn't the best option in this case. If it can be done with a Snippet instead then that's fine with me. I'm just not sure how to do that.

These chunks are in the resource content? Chunk A in page 1, and Chunk B in page 2?

Not sure what you mean by 'resource content'. I put the Chunk(s) tag in the Resource(s) template, if that's what you mean.

So all pages using the template get both chunks? Can you post the affected part of the template's HTML code showing the chunk placement? (use the < > code button to show the code properly)

Susan is referring to the "Resource Content" field of the Create/Edit Resource panel, though putting them in the template seems fine.

Here's a generic snippet (untested) that will return the value of any TV for any Resource:

[[!ShowTv? &tvId=`12` &resourceId=`14` &render=`0`]]

<?php
/* ShowTv snippet */

$rid = $scriptProperties['resourceID'];
$render = isset($scriptProperties['render']) && $scriptProperties['render'];
$tv = $modx->getObject('modTemplateVar', $scriptProperties['tvId']);

if ($tv) {
    return $render? $tv->renderOutput($rid)  : $tv->getValue($rid);
} else {
   return "TV Not Found";
}

If &render is 0 or missing, you'll get the raw value of the TV, which will be faster if you don't need MODX to render it.

BTW, if the value will be shared across multiple resources, you might consider making it a System Setting, which would be available anywhere as:

[[++SettingName]]

PLEASE, PLEASE specify the version of MODX you are using.

No. There are 2 templates.

Page 1 uses Template 1 and Chunk A
Page 2 uses Template 2 and Chunk B

Chunks A and B share two TVs ('projectName' and 'projectEmail').

From Template 1:

<!-- !Begin Project Info -->
				
[[$projectInfo]]

<!-- !End Project Info -->

And Chunk A 'projectInfo' (above):

<ul>
<li>[[*projectName]]</li>
<li>[[*projectEmail]]</li>
</ul>

I want to insert the values for 'projectName' and 'projectEmail' from Page 1/Template 1 into Page 2/Template 2.

Hopefully that makes sense.

Ok, different templates.

For the TV in #2, use a snippet like BobRay suggested instead of TV tags. If you don't want to edit the TV for resource #2, then don't have its template assigned to the TV.

So if I used Bob's example above I would create 2 Snippets to replace each TV, 'projectName' and 'projectEmail'. Is that correct?
