Fetching custom TV on AMP pages.

danilpro — Apr 27, 2018, 06:05 AM

Hello, I'm fairly new to MODX system and I need a little help. We have amp pages which retreive the main content of the page in the following way:

'content' => $resource->get('content')

The problem is, this content is meant for full desktop pages and can't get validated, so I need custom AMP friendly content retreived instead of raw "content". I've created a TV named "amp-content" and I try to get it on AMP pages instead of content. Here is the current code in AMP Template:

Template code:

[[+amp_ptitle]]
    
    [[+amp_content]]

Snippet:

$modx->setPlaceholders(array(
        'ptitle' => $resource->get('pagetitle'),
        'pdescription' => $resource->get('description'),
        'content' => $resource->get('content'),
        'canonical' => $modx->makeUrl($resource->get('id'),'','','full'),
        'published' => $resource->get('publishedon'),
        'edited' => $resource->get('editedon'),
        'image' => $image_url,
        'image_width' => $width,
        'image_height' => $height
    ),'amp_');

So I'm trying to do something with this line:

'content' => $resource->get('content'),

What I want to do is: if there is amp-content TV available - fetch it, if not - get normal content.
Obviously, options like this don't work

'content' => $resource->get('amp-content'),

Also, I've tried

'content' => $tvr->get('amp-content'),

No luck.
So, is it possible to do something here, I'm new so this might be a noob question, thank you very much

I think this would do it:

Thank you, BobRay, it works!

I think this would do it:

$tvValue = $resource->getTVValue('amp-content');
$docContent = empty($tvValue)? $resource->get('content') : $tvValue;
$modx->setPlaceholders(array(
        'ptitle' => $resource->get('pagetitle'),
        'pdescription' => $resource->get('description'),
 
        'content' => $docContent,

        'canonical' => $modx->makeUrl($resource->get('id'),'','','full'),
        'published' => $resource->get('publishedon'),
        'edited' => $resource->get('editedon'),
        'image' => $image_url,
        'image_width' => $width,
        'image_height' => $height
    ),'amp_');

You could do it with a little less code like this if you change the ptitle and pdescription placeholders to pagetitle and description:

$fields = $resource->toArray();
$tvValue = $resource->getTVValue('amp-content');
$fields['content'] = !empty($tvValue)? $tvValue : $fields['content'];
$fields = $array_merge($fields, array(
    'canonical' => $modx->makeUrl($resource->get('id'),'','','full'),
    'image' => $image_url,
    'image_width' => $width,
    'image_height' => $height,
));
$modx->setPlaceholders($fields, 'amp_');

Thank you, Jako, it works. Could you please advise how can i combine these two lines into "if {amp-content} is not available, then put {content}"?
That's pretty much all I need. Thank you!

$modx->setPlaceholders(array(
        'ptitle' => $resource->get('pagetitle'),
        'pdescription' => $resource->get('description'),


        'content' => $resource->get('content'),
        'content' => $resource->getTVValue('amp-content'),


        'canonical' => $modx->makeUrl($resource->get('id'),'','','full'),
        'published' => $resource->get('publishedon'),
        'edited' => $resource->get('editedon'),
        'image' => $image_url,
        'image_width' => $width,
        'image_height' => $height
    ),'amp_');

If you really want to work with a different amp-content template variable (because you have to handle two content fields). TV content could be retrieved this way.

'content' => $resource->getTVValue('amp-content'),

Is there a way to do it without installing new things?
We already have AMP working, that's not the issue. I just need to convert the resource content into amp friendly content, that's it

Look for the SwitchTemplate extra. It could switch the template to amp on the fly.

How are you serving amp pages currently is it via the amp pages extra, switch template extra or another way? In the first two extras you're serving a different template anyway for amp pages so you could just replace the tvs with some amp specific created ones.

Like this:

The amp urls structure looks like this:
site.com/amp.html&page=page-slug
