PopUp Relations

This modification was only tested in vtigerCRM 6.1.

This modification could decrease the frontend performance a little, because it needs to be integrated into every EditView. Regardless if you use this feature in the module.
In modern Browsers you won't recognize this.
It execute 2 database Queries on the EditView/CreateView and one in the PopUp.

At first please install the latest version of VtigerCRM Tools

CREATE TABLE IF NOT EXISTS `vtiger_popup_relation` (
`id` INT(11) NOT NULL,
`src_module` VARCHAR(30) NOT NULL,
`src_field` VARCHAR(50) NOT NULL,
`module` VARCHAR(30) NOT NULL,
`search_key` VARCHAR(50) NOT NULL
) ENGINE=InnoDB ;
 
ALTER TABLE `vtiger_popup_relation`
 ADD PRIMARY KEY (`id`), ADD UNIQUE KEY `src_module` (`src_module`,`src_field`,`module`);
 
ALTER TABLE `vtiger_popup_relation`
MODIFY `id` INT(11) NOT NULL AUTO_INCREMENT;

You now could use this feature.
You need to insert a new line in the just created table vtiger_popup_relation.

You get the values if you open the PopUp you want to modify.
