I have a custom post type "Seller""Propietario" with 3several custom fields, and 3 of them: "name""dni", "email" and "phone" inserted in a metabox in admin PageI need unique for all Propietario Post types. This CPT is only accesible throw admin wordpress page.
I want that@vijay-pancholi's answer has made me understand what is the flow when registering new custom fields "email" and "phone" are unique for all sellers. And after this I mean, 2 sellers cant have same email or phoneedited my answer. This validation must be for the only custom post type "Seller" and only published posts
WhatI am using object-oriented programming for creating my CPT since it is part of a more complex plugin. The method involved, which stores the correct wayfields, is "properties_save_fields_owner". The code is more complex but I have tried to use add_post_meta or update_post_meta in metabox in registerreduce it to cancel registration if already have registered a Seller withshow only the code involved for this email or phone?problem:

I would like validate fields before fields registration and display a error message if there are email or phone and cancel cpt registration. WhatAfter debugging, the main problem is that the way recommendedmethod inmuebles_save_fields_propietario is executed several times. Anyone show me a correct example?When I am searchingtry to create a examplenew CPT it runs right when the metabox opens clicking in docummentation but I didnt find this case"add new". That's why I added the line:
if (!empty($id) || !empty($email) || !empty($telephone)) {
Im a Laravel developerAnd the code is correct, but even if the line is executed:
wp_die('There is already an owner with the same ID, phone number or email. <br> <a href="javascript:history.back()">Back</a>', 'Error', array('response' = > 400));
The method is executed again and would like understandfor some reason that I don't know the logic in a customCPT is registered. You register with empty fields registration, but a new Owner is created. Its
I have tried adding exit() after the wp_die, but there is no way I can prevent the method from being executed again, and therefore a little bit differentnew CPT is registered.
Kind regardsHow Can I stop registration of CPT when display the error?
