Help needed with writing a header image rotation script
I want to include a small script to rotate the image in the header so that it displays an alternative image on certain special days which I can specify. A bit like Google does.
I am running VB4.2 PL2 Here is the script, which is kept in a file called 'headerrotate.php' in my plugins/headerrotate/ folder : PHP Code:
And it says I first need to create a plugin, which I have done... however when I make the plugin active (all image files that are referenced are uploaded, as is the php file) all that happens is a blank page, so I am assuming that something is wrong because what 'should' happen is that it returns the image variable, and as this is not used at present until I change the header template to include it in the code, it would do nothing... This is my plugin code : Quote:
Finally, it also mentions in the tutorial that in vBulletin 4+, you need to register variables for them to be available in specific templates and usable. You would do this with code like this: vB_Template:reRegister('FORUMHOME',array('includ edphp ' => $includedphp)); What does this mean, and where would I do this? Is this why I'm getting my blank page? Any help would be greatly appreciated |

Code:
vB_Template::preRegister('header',array('headerrotate' => $includedphp)); I should also mention that unless you *want* your code to be in an external file, you could put it all in the plugin. If you did that, your plugin code would look like this: Code:
// example random image based on time // fetch date unit that we will be using. d:m will give the day and month in numeric form with leading 0 // You can find other date units aside from 'd:m' on http://www.php.net/date // You could also combine these, for example 'H:i" will give you hours:minutes $HeaderDateUnit = date('d:m'); // the switch statement compares the variable $HeaderDateUnit to every "case" // if it matches, whatever command after the colon is performed. // the break; statement tells the switch statement to stop attempting comparisons // Before we break;, we assign an image filename to $image variable. // The default : is what happens if the switch statement doesn't match anything to $HeaderDateUnit. switch($HeaderDateUnit) { // New Year case "01:01" : $image = "images/misc/headers/newyear.png"; break; // King's Day case "06:01" : $image = "images/misc/headers/kingsday.png"; break; // Valentine's Day case "14:02" : $image = "images/misc/headers/valentines.png"; break; // Default image default : $image = "images/misc/vbulletin4-logo.png"; break; } vB_Template::preRegister('header',array('headerrotate' => $image)); Also I would recommend using hook location parse_templates. global_start would probably work most of the time, but there's a chance that it would be too late to add something to the header template in the case where another plugin did something with templates. |
