premiso Posted November 17, 2009 Share Posted November 17, 2009 header.php <html> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <head> <meta http-equiv="Content-Language" content="en-us"> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title><?php echo EMS_CAD; ?></title> <link rel="stylesheet" href="style.css" type="text/css" media="screen" /> <?php if (function_exists("add_to_head")) { echo add_to_head(); } ?> </head> Try that. You only need to open PHP tags when you plan on executing PHP code. Also: index.php <?php add_to_head("<link rel='stylesheet' href='blue.css' type='text/css' media='screen' />");?> You had a syntax error with the double quote after blue.css.

premiso Posted November 17, 2009 Share Posted November 17, 2009 Well look up the function in the manual and do some debugging to figure out why the delimiter is empty. stristr Link to comment https://forums.phpfreaks.com/topic/181894-function-add-code-to-head/#findComment-959499 Share on other sites More sharing options...
