Method for checking conditions before editing

QuestionsMethod for checking conditions before editing
Richard Kooijman asked 6 years ago

Hi Abu,
Do we have a method available for an ajax call in which we can check conditions (like other table values) before opening the edit form and show a message box in case it is not possible or allowed to edit the current record? E.g. to prevent changing a record that is being edited by another user.

This function is not exactly available, however there are alternates.

First you can use afterShowForm event to invoke ajax call … and show error message alert.

$grid["add_options"]["afterShowForm"] = 'function(formid) { }';

Same can be used for edit_options.

Second, you need to put same check in on_update event (as server side validation)
You can refer demos/editing/server-validation.php
