#9166 – Twitter image - where to set it?

Hi

You can manually set that in the user interface of course but if you want to do it programmatically, you should either:

- Disable 4SEO Twitter Cards generation and create them yourself as you see fit, using Joomla addCustomTags or otherwise

- Use the corresponding 4SEO filter:

In /libraries/weeblr/forseo_functions.php (create or edit), add:

<?php
/**
 * 4SEO hooks file
 *
 * You can use 2 variables to access 4SEO content:
 *
 * $factory: access variables
 * $hooks: add handlers
 */

// no direct access
defined('WBLIB_EXEC') || die;

$hooks->add(
	'forseo_request_info',
	function ($requestInfoData) {

		$requestInfoData['page_custom_sharing_image'] = [
			'url' => 'httpsurl/to/your/image'
		];

		return $requestInfoData;
	}

);

You can check the content of the request info array for other values you may want to modify on the fly.

Hi

If I disable both my OG Tags are added.

Well, first you don't to disable 4SEO entirely. You can just disable the Open Graph OR Twitter cards feature (Configuration | Social networks).

Second, yes, if Twitter card feature is enabled in 4SEO, it will output Twitter Cards. I'm sure the same for TAGZ.

joomla ignores my custom tags completely

I don't know about that. 4SEO also uses Joomla's $document->addCustomTags() to output TwitterCards or OGP data.

At which point in time are you outputting your custom tags? which event? maybe it's too late in the process?

Hi

have the possibility to override it in the template

Why would you do that in the template when we have an entire code override mechanism in place, super easy to use and that works with any template (because it's not linked to the template)?

Hi

 I am not sure how to do it with your suggested way.

The same, there's no difference. Well, you have to do 

$document = Factory::getApplication()->getDocument();

first but then it's just Joomla code running inside of Joomla rendering process. Nothing special here.

Hi

Indeed, if using non-Joomla content, then you'd need to be able to access that. I don't know how and when Seblod defines that variable, I assume they have some way to intantiate it but if not, then you cannot use it outside of your view template override indeed.

 Would be good to use 4seo and have the possibility to override it in the template.

To be honest, I'm not sure why it does not work, ->addCustomTags() is just adding some raw tag content. We should have both at least, yours and 4SEO's.

Hi again,

I just tested to be sure, and I have no problem adding any custom tag to the document head from the template:

- copied default.php from /components/com_content/tmpl/article/default.php to /templates/cassiopeia/html/com_content/article/default.php

- added the following to the start of the override:

Factory::getApplication()->getDocument()->addCustomTag(
        '<meta property="og:locale" content="fr_FR" class="from_template">'
);

and sure enough I get BOTH this one and the 4SEO ones, which is exactly what I would have assumed, as addCustomTag() does nothing special, does not consider duplicates, etc, it's just raw text added to the page source code.

So if your custom tags do not appear, there's more to it than just 4SEO interfering here.

Hi

 maybe 4 SEO is fired after the SEBLOD Content Plugin

That does not matter, we are not using a content pluing and alos we are just using $document->addCustomTag() so we are not removing anything from the page.

What I see when I do that, and what you should get, is that addCustomTags() works and you should have both tcards in your page source code (BTW, do you check by looking up the source code? if using an extension or Twitter debugger, they'll will likely only report the first tcards they find, not all).

I got it running like that and the customer is happy.

Yeah, but I am a "product developer", not a website developer: different way to look at things, I want to understand what's going on, not so much fix the problem right away ;)

Anyway, having SEBLOD in the picture here is too much trouble, not something I want to get involved with really. Is there or will there be a Seblod for Joomla 4?
