Open Graph - Intro Image

[componentegd]

Hello!
First of all, I love this plugin! I use it always.

I'm trying to use the plugin capturing the image directly from the "Intro image", you can put an image there clicking into "Images and links" and then "Intro image".



I saw a lot of posts in here, but I didn't found any of them talking about it.

Can anyone help me?
Thanks in advance!

Hi, if you are able to customize it (php skills) and you will modify it for your self, will be great to get a guide

Ok. I'll try something and I'll post here soon as I get some answer.
My greatest problem with joomla is that I'm not that good with OO.

Ok

I manage to find a solution, but I would like a help to make it "pro" solution.

I'll post here the code I used to it, but it only will work if there is no image into the article, only in the "intro image".

Code: Select all

// Article Image
			$article = JTable::getInstance("content"); 
			$article->load(JRequest::getInt("id")); // Get Article ID
			$article_images = $article->get("images"); // Get image parameters
			$pictures = json_decode($article_images); // Split the parameters apart
			// Print the image
			//echo "<img src='" . $pictures->{'image_intro'} . "' alt='" . $pictures->{'image_intro_alt'} . "'>";
			$document->setMetadata('og:image', $pictures->{'image_intro'});

I'll post now where is it being to work

Code: Select all

// Image
		
		// Article Image
			$article = JTable::getInstance("content"); 
			$article->load(JRequest::getInt("id")); // Get Article ID
			$article_images = $article->get("images"); // Get image parameters
			$pictures = json_decode($article_images); // Split the parameters apart
			// Print the image
			//echo "<img src='" . $pictures->{'image_intro'} . "' alt='" . $pictures->{'image_intro_alt'} . "'>";
			$document->setMetadata('og:image', $pictures->{'image_intro'});
		
		if ($this->params->get('image'.$suffix, '') != '') {
			$document->setMetadata('og:image', JURI::base(false).htmlspecialchars($this->params->get('image'.$suffix, '')));
		} else {
			// Try to find image in article
			$img = 0;
			$fulltext = '';
			if (isset($row->fulltext) && $row->fulltext != '') {
				$fulltext = $row->fulltext;
			}
			

Jan, do you think we can get it to work better? I'm not that expert into PHP skills. Besides, OO kills me lol

Hi, which file you are trying to customize and which version of the plugin?

Hi! I'm using the last version of the plugin.
The file is: "plugins/content/phocaopengraph/phocaopengraph.php"

I just added that code posted above. But I would like to make this work better.

[Jan]

Ok, will be great if you can paste whole code of the phocaopengraph.php

If you will use GIST (on GitHub) will be great - to see the changes.
