Thank you for your reply.
I found that it works when adding the following event to “acf.validation events” on line 12847 of acf-input.js.
acf.validation = new acf.Model({
/** @var string The model identifier. */
id: 'validation',
/** @var bool The active state. Set to false before 'prepare' to prevent validation. */
active: true,
/** @var string The model initialize time. */
wait: 'prepare',
/** @var object The model actions. */
actions: {
'ready': 'addInputEvents',
'append': 'addInputEvents'
},
/** @var object The model events. */
events: {
'click input[type="submit"]': 'onClickSubmit',
'click button[type="submit"]': 'onClickSubmit',
'click #save-post': 'onClickSave',
'mousedown #post-preview': 'onClickPreview', // use mousedown to hook in before WP click event
'submit form': 'onSubmit',
'mousedown #custom-preview': 'onClickPreview' // Add New
},
However, I didn’t know how to add this process without changing the core file. (I know that filters model.filters exists, but I didn’t know how to write correctly.)
How can I add events to acf.validation?
