Parent page properties

Hi guys,

I’d like to access properties about the parent of a page in the template. I’ve discovered [[*parent]], which kinda gives a link to the parent. However, it’s not perfect, as instead of getting "/parent/child", I get "/parent/4". Is there a way to get the correctly resolved SEO URL for the parent? Can I also get properties of the parent? For instance [[*parent.description]] or [[*parent.someTV]]???

Thanks loads,
Lee

How are you linking to the parent? This should output a friendly url for you:

[[~[[*parent]]]]

Can I also get properties of the parent? For instance [[*parent.description]] or [[*parent.someTV]]???

Install the getResourceField extra, then do this:

[[getResourceField? &id=`[[*parent]]` &field=`description`]]   // for parent description
[[getResourceField? &id=`[[*parent]]` &field=`myTV` &processTV=`1`]]   // to get parent TV

Wonderful, thanks

I started looking into writing a snippet to do this, but I’ll always opt for the easy option, if it’s available ;-)

Thanks again.

In case you want a snippet (which would be somewhat faster and more efficient), this should help:

<?php
$parentObj = $modx->getObject('modResource', $modx->resource->get('parent'));

$parentPagetitle = $parentObj->get('pagetitle');
$parentPublished = $parentObj->get('published');
// etc. for any field except content, use $parentObj->getContent() for that.

You can set placeholders for all parent fields with this (though it may be slower because it will set a bunch of placeholders you don’t need):

$modx->toPlaceholders($parentObj->toArray(), 'parent');

With the above line, the placeholders will have the prefix ’parent.’ to avoid collisions, so they’d show with:

[[+parent.pagetitle]]
[[+parent.content]]

etc.

$modx->toPlaceholders($parentObj->toArray(), 'parent');

In that case, I guess you could just use setPlaceholders to just output the ones you need:

<?php
$parentObj = $modx->getObject('modResource', $modx->resource->get('parent'));
$modx->setPlaceholders(array(
   'pagetitle' => $parentObj->get('pagetitle'),
   'published' => $parentObj->get('published'),
),'parent.');

I often use a similar technique which allows me to set a comma-delimited list of required placeholders in my snippet call, which is then exploded into an array and then fed to setPlaceholders as above. Works fine

FWIW, I would use...

<?php
if ($modx->resource->getOne('Parent')) {
    $modx->toPlaceholders($modx->resource->Parent->get(array('pagetitle', 'published')), 'parent');
}

This would use the Parent relation if it was loaded during the request already (avoiding an additional query where possible), and you can use an array as the first parameter of the get() method to retrieve an array of specific attributes from the Parent object to pass to the toPlaceholders() method.

I can’t believe I didn’t think of getOne(’Parent’). I’ve written about it dozens of times. I guess I need more sleep. tongue
