vBulletin: The Secret to Developing vB Plugins

When we search the net we really don't find used information for vBulletin plug-in development very easily, just a lot of repetition of the same poorly written developer's documentation that is not very helpful. After years of frustration with trying to understand the sparse documentation on developing vBulletin plug-ins, I have finally made some headway and thought I would share some "dirty little vB secrets".

First of all, one of the most important parts of developing a vB plug-in is creating options and settings. and you can search in your vB control panel for months and never find how to do it. That is because to create settings you must edit the config.php file and add the following line:

Code:

$config['Misc']['debug'] = true;

Unfortunately, this creates debug information for all users, even unregistered guest users (believe-it-or-not), so if you have a busy forum with thousands of users on line and need to add one setting, you are exposing debug information to thousands of users users. The solution, however, is simply:

Code:

if($_SERVER['REMOTE_ADDR'] =='YOUR.IP.ADDR.HERE')
$config['Misc']['debug'] = true;

Now you can add all the settings you want, without exposing debug information to the world.

In my next post on this topic, I'll share with you the next vB plug-in developer's secret, how to easily use the settings you can now easily create.

picld_plugin_register

picld_plugin_register(3PICLTREE)			  PICL Plug-In Library Functions			  picld_plugin_register(3PICLTREE)

NAME

       picld_plugin_register - register plug-in with the daemon

SYNOPSIS

       cc [ flag... ] file... -lpicltree [ library... ]
       #include <picltree.h>

       int picld_plugin_register(picld_plugin_reg_t  *regp);

DESCRIPTION

       The  picld_plugin_register() function is the function used by a plug-in module to register itself with the PICL daemon upon initialization.
       The plug-in provides its name and the entry points of the initialization and cleanup routines in the regp argument.

	 typedef struct {
	     int   version;		  /* PICLD_PLUGIN_VERSION */
	     int   critical;		  /* is plug-in critical? */
	     char  *name;		  /* name of the plugin module */
	     void  (*plugin_init)(void);  /* init/reinit function */
	     void  (*plugin_fini)(void);  /* fini/cleanup function */
	 } picld_plugin_reg_t;

       The plug-in module also specifies whether it is a critical module for the proper system operation. The critical field in  the  registration
       information  is	set  to  PICLD_PLUGIN_NON_CRITICAL by plug-in modules that are not critical to system operation, and is set to PICLD_PLUG-
       IN_CRITICAL by plug-in modules that are critical to the system operation. An environment  control  plug-in  module  is  an  example  for  a
       PICLD_PLUGIN_CRITICAL type of plug-in module.

       The PICL daemon saves the information passed during registration in regp in the order in which the plug-ins registered.

       Upon initialization, the PICL daemon invokes the plugin_init() routine of each of the registered plug-in modules in the order in which they
       registered. In their plugin_init() routines, the plug-in modules collect the platform configuration data and add it to the PICL tree  using
       PICLTREE interfaces(3PICLTREE).

       On reinitialization, the PICL daemon invokes the plugin_fini() routines of the registered plug-in modules in the reverse order of registra-
       tion. Then, the plugin_init() entry points are invoked again in the order in which the plug-ins registered.

RETURN VALUES

       Upon successful completion, 0 is returned. On failure, a negative value is returned.

ERRORS

       PICL_NOTSUPPORTED    Version not supported

       PICL_FAILURE	    General system failure
