Error function explained

[joeroberts]

To generate a basic error report you can use 1 of 3 PMBT error functions
first is the btsqlerror which is the Mysql error

PHP Code:

btsqlerror($sql = '') 


where $sql is the query
example

PHP Code:

        $sql = "SELECT id FROM ".$db_prefix."_users WHERE id = '".$user->id."' AND username = '".$user->name."' AND act_key = '".addslashes($userdata[3])."' AND password = '".addslashes($userdata[2])."';"; 


this well return a fatal error causing the script to come to a complete stop
and display a error block reporting the query the error code and Mysql message for this error
to use this

PHP Code:

                        $sql = "SELECT avatar FROM ".$db_prefix."_users WHERE id = '".$uid."';";
                        $res = $db->sql_query($sql)or btsqlerror($sql); 


the Second is the display error bterror

PHP Code:

bterror($error, $title = _btgenerror, $fatal = true) 


$error is the body of the error block and is a required field
$tittle is the header of the error block this field is not required
$fatal tells the script if it should come to a complete stop or just carry on after display By default it is fatal and well stop the script.
example Fatal Error

PHP Code:

bterror("Error","you have a fatal error"); 


Example Non Fatal error

PHP Code:

bterror("Error","you have a nonfatal error",false); 


the last is error log

PHP Code:

logerror($message, $error = _btgenerror) 


this well write a log error in the data base of the error for site admin to view
in the admin logs
$message is the main error and is required
$error is the title of the error and is not required
this well add to the data base a row for error type error body user IP the created the error and a time stamp
Example

PHP Code:

logerror('User login failed for '.$username, 'Failed Login');
