Native function to add code to Head

[Azrael]

Hi,

Can anyone tell me the native Joomla function to add code to the head of the page? I need it to add custom open graph tags. Thanks advance.

[jbuzzeo]

there are several extensions that claim to handle this in the JED -> http://extensions.joomla.org/

I don't actually have experience with any of them, but it's a place to start

There is no native function for OG tags though there is for http-equiv and name (http://docs.joomla.org/JDocument/setMetaData)

Use a plugin from the list at http://extensions.joomla.org/extensions ... open-graph or add these lines to the head php tag of index.php

Code: Select all

$app = JFactory::getApplication();
$document = JFactory::getDocument();
$og	= '<meta property="og:title" content="'.$document->title.'" />' ."\n";
$og .= '<meta property="og:type" content="Magazine" />' ."\n";
$og .= '<meta property="og:url"  content="'.rtrim(JURI::base(), '/').$_SERVER["REQUEST_URI"].'" />' ."\n";
$og .= '<meta property="og:image" content="'.JURI::base().'images/ogimages/default.png" />' ."\n";
$og .= '<meta property="og:site_name" content="'.$app->getCfg('sitename').'" />' ."\n";
$og .= '<meta property="fb:admins" content="65745237346832" />' ."\n";

$document->addCustomTag($og);

Actually what I need is a function to add code to the head of the page. I know how to add og tags, but I want a function that will inject a custom code (where I have all the og tags) to the head of that page.

[jackrabbit]

$document->addCustomTag($og); will add the code to the head. Other head functions are
addStyleSheet()
addStyleDeclaration()
addScript()
addScriptDeclaration()
setMetaData()

and many more. Your original question specifically said you want to add custom OG tags and that is what the code I laid out will allow. Otherwise you will need to layout a precise and sensible explanation of your ultimate goal.

I apologize for not being more precise. I'll try to explain it in detail. Are you familiar with the jReviews extension?

[jackrabbit]

I know of it but have never used it.

[Azrael]

I'm using it for music. It allows you to add custom fields to each listing (which works as a joomla article) and one of those fields I insert several OG tags together.

So I need a function which will tell jReviews to send the data on that custom field to the head of the page, to include those OG tags.

Well now you are outside the Joomla core. It is neither general or new to joomla. This should have been posted in the forum relative to extensions http://forum.joomla.org/viewforum.php?f=620
