Joomla! display article based on URL in stead of 404 page

Question

We have a website based on Joomla! in the joomla directory, there are many other directories, ie:

C:\myjoomlawebsite
  ...joomla directories...
  \myspecialdirectory

in "myspecialdirectory" there are resources that sometimes are available and other times are not available, as one would imagine, when a resource(php page) is not available, a 404 page is displayed.

What I would like to do is, "somehow" tell joomla that when the user tries to access a page located in "myspecialdirectory" and it's unavailable, it should show an article page rather than a 404.

• if the user accesses mydomain.com/ <- all good
• if the user accesses mydomain.com/existingpage.php <- all good
• if the user accesses mydomain.com/unavailablepage.php <- a 404 should be shown
• if the user accesses mydomain.com/myspecialdirectory/existingpage.php <- all good
• if the user accesses mydomain.com/myspecialdirectory/unavilablepage.php <- here's where I want the user to see a article page in stead of a 404

Answer 1

Check this

For v1.5

if (($this->error->code) == '404') {
header('Location: /index.php?option=com_content&view=article&id=75');
exit;
}

For 1.6 & 1.7

if (($this->error->getCode()) == '404') {

Answer 2

Because that directory is outside of the Joomla framework, and you only want one directory to redirect to a Joomla page instead of a 404, then the easiest way to accomplish this is to use put a custom htaccess in the directory you want to redirect. You would want to add this to htaccess only in myspecialdirectory

ErrorDocument 404 /URL TO JOOMLA ARTICLE.php
