Make a Field Conditionally Required

This article provides instructions for making a field conditionally required.

In the steps that follow, the example code is used to ensure the Assignee is the only only able to close a ticket. Other examples are displayed at the bottom of this article.

Step 1. Create the script

The script is created as a .spl file and placed in the site/mods/majic directory.

CODE

cr::zmyscript(...) {
string zmsg;
if(assignee.userid != cst.userid) {
zmsg=format(" Assignee must be the same as the logged in user in order to close %s", ref_num);
set_error(1);
set_return_data(zmsg);
return;
}
}

Step 2. Create the trigger

The trigger is responsible for "triggering" the script.

r11.x triggers are created via the Schema Designer utility. Simply add a Site-Defined Trigger to the desired table.

CODE

PRE_VALIDATE zmyscript() 113 FILTER(active == 0);

pre-r11.x triggers are made by creating a .mod file and placing it in the site/mods/majic directory.

CODE

MODIFY cr PRE_VALIDATE zmyscript() 113 FILTER(active == 0);

Step 3. Publish the Schema changes

r11.x 1. Save your Schema changes 2. Stop the Service Desk service 3. Run pdm_publish from a command line 4. Start the Service Desk service

pre-r11.x Recycle the Service Desk service

Note: This logic can be used to greatly expand system functionality by ensuring that data gets collected when any number of conditions exist.

Tips

String statements together using && Example (is_null(anyfield1) && is_null(anyfield2))

For not null add an ! Example (!is_null(anyfield))
