Error message when combining Phoca Open Graph with DPCalendar

Post by jdiamond »

I see the following error from Phoca Open Graph plugin when viewing DPCalendar events:

Code: Select all

[06-Jun-2019 17:47:47 UTC] PHP Warning:  json_decode() expects parameter 1 to be string, object given in /home/nydi/public_html/plugins/content/phocaopengraph/phocaopengraph.php on line 97
Some debugging has shown that the problem is that the event item passed to onContentAfterDisplay has an $item->images of type object.

As I understand the interface, plugins are supposed to check if the passed item is an article and only if so treat it as string.

For the moment I have hacked in the following patch:

Code: Select all

                        plgContentPhocaOpenGraphHelper::renderTag('og:image', JURI::base(false).$this->params->get('image'.$suffix, ''), $type);   
Would it be possible to apply this fix in the next version of the Open Graph plugin?
