The usage of laravel unique is "'email' = > [' required', 'email',Rule::unique (' customer')->})],", which means that when the update information detects whether the mailbox is duplicated, it excludes itself and all users with a status of 4.

The operating environment of this tutorial: windows7 system, Laravel5.5 version, DELL G3 computer.

Use of Laravel unique rules

The use of unique for laravel:

$customer_type = request ('customer_type', 1) $attributes = request ()-> validate (['gender' = >' required | min:0 | max:3', 'chinese_name' = >' nullable | min:2', 'english_name' = >' nullable | min:3', 'area_phone_number' = >' required | numeric', 'telephone' = >' required | numeric', 'email' = > [' required', 'email' Rule::unique ('customer')-> ignore (request (' id'))-> where (function ($query) {$query- > whereNotIn ('status', [4])) })], / / 'email' = >' required | email | unique:customer,email,'. Request ('id'),' password' = > 'nullable | string | min:6',' concurrent_login_num' = > 'required | min:1 | integer',' child_age' = > 'nullable | integer | min:0',' remark' = > 'nullable | string | max:1024',' status' = > 'required | integer | min:0 | max:4',])

Pay attention to this usage:

'email' = > [' required', 'email', Rule::unique (' customer')-> ignore (request ('id'))-> where (function ($query) {$query- > whereNotIn (' status', [4]);})]

This means that when the update information detects whether the mailbox is duplicated, exclude yourself, and exclude all users with a status of 4. In my case, a user with a status of 4 is deleted. If this mailbox is used by the deleted user, then repeatability is not checked.
