I'm going to explain: I'm new to Joomla! and I have 3 modules in which I have to rewrite the URLs for SEO purposes.

In order to rewrite URLs has been provided this solution on SE WebMasters. It implies me to add a <link> tag in the <head> of the page so I would like to know if there is a Joomla-core method with which I can add such tag in the <head>.

In general, below is the code.
$doc = JFactory::getDocument();
$doc->addHeadLink(htmlspecialchars(JURI::current()), 'canonical');

I was looking for the Joomla documentation and only found one from Joomla 1.7. Not sure if the documentation just hasn't been updated or there have been some changes. https://docs.joomla.org/API17:Subpackage_Document

  • addHeadLink() isn't a core php function - so it can't be called like this - this should be JDocumentHTML::addHeadLink(); or $doc = JFactory::getDocument(); $doc->addHeadLink();

  • Thanks @FFrewin, I made the edit. I just did a sloppy copy/paste from file on my computer. Do you know if the documentation is just out of date or are they moving away from this?

  • haven't check the link you posted - although this is the J17 API - and currently I don't have the time to review and compare the old API with the new one for any differences.
