Vbulletin plugin development tutorial

I searched for tutorials but i didn't found any useful tutorial. I want to create simple plugin which a开发者_StackOverflowdd "123" to header of every pages of forum.

I tried to go to admin panel -> create new plugin. But i don't know what hook i need to display "123" in header.

I will be very thankful for any help.

Assuming vBulletin 4 and above:

Create a Product

1. Logon to your AdminCP
2. Goto Plugins & Products -> Manage Products
3. Click Add/Import Product
4. On the following screen enter your product name etc in the Add New Product section (you can leave Product URL and Product Check URL blank)

Add a Plugin to your Product

1. Goto Plugins & Products -> Add New Plugin
2. Select your Product
3. To add something to the header on every page select the global_bootstrap_init_complete hook location

4. In PHP code enter the following:

   $template_hook['mycustommesage'] = 'hello world';

Update your header template to include the plugin output

1. In ACP goto Styles & Templates -> Style Manager
2. Select the style you want to edit and select edit templates
3. Open the header template

4. Whereever you want you plugin output to appear add:

   {vb:raw template_hook.mycustommesage}
