As far as i can tell everything on the script is working excecpt the script detecting the logged in userid... when i send a message from user to user it does not up date the the "from" row of my mysql table.

 

// Set the userid to 2 for testing purposes... you should have your own usersystem, so this should contain the userid

    $userid=2;

I think this part is part of the problem.. I've tried $userid='loginid'; which is the user id of my members table.. Please help me figure out what im doing wrong and thanks in advance

 

the table

CREATE TABLE `messages` (
`id` INT( 11 ) NOT NULL AUTO_INCREMENT PRIMARY KEY ,
`title` VARCHAR( 255 ) NULL 
`message` TEXT NOT NULL ,
`from` INT( 11 ) NOT NULL ,
`to` INT( 11 ) NOT NULL ,
`from_viewed` BOOL NOT NULL DEFAULT '0',
`to_viewed` BOOL NOT NULL DEFAULT '0',
`from_deleted` BOOL NOT NULL DEFAULT '0',
`to_deleted` BOOL NOT NULL DEFAULT '0',
`from_vdate` DATETIME NULL ,
`to_vdate` DATETIME NULL ,
`from_ddate` DATETIME NULL ,
`to_ddate` DATETIME NULL ,
`created` DATETIME NOT NULL
) ENGINE = MYISAM ;
