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;
//Enter your if statement
if(is_null(string1)) {
//Enter your alert message that appears when the if statement is fulfilled
zmsg=format(" string1 is required in order to close this ticket");
set_error(1);
set_return_data(zmsg);
return;
}
}

Step 2. Create the trigger

This step is to create the trigger that will initiate the script. The methods used to implement the script vary based on the Service Desk release.

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))
