!!WARNING!!

If the text that you place between the single quotes in the $kdm_adsense[1] variable has any single quotes in it then you must escape them otherwise IT WILL NOT WORK.

You will get an error like similar to "Parse error: parse error, unexpected '}' in /home/content/O/p/e/OpenTutorial/html/extensions/kdm/kdm_adsense.php on line 21"

Example:

• $kdm_adsense[2] = '<form action="https://... - it\'s fast, free and secure!"></form>'

  • works just fine

• $kdm_adsense[2] = '<form action="https://... - it's fast, free and secure!"></form>'

  • will crash your wiki

Installation

• create a directory kdm in the extensions directory
• place kdm_adsense.php in the extensions/kdm directory (see code below)
• open the file LocalSettings.php, search for:

?>

and change this to:

    require_once('extensions/kdm/kdm_adsense.php');  // kdm adsense Extension

?>

• in the function wfadsenseExtension, place the code for your adsense-buttons in the variable $kdm_adsense.

Usage

• the tag <adsense> is translated to the button defined in $kdm_adsense[1].
• the tag <adsense>2</adsense> is translated to the button defined in $kdm_adsense[2].
• the tag <adsense>2 description</adsense> is translated to the button defined in $kdm_adsense[2], additionaly the text 'description' is placed next to the adsense button.
• the tag <adsense>description</adsense> is translated to the button defined in $kdm_adsense[1], additionaly the text 'description' is placed next to the adsense button.
