laravel valitation rule to remove whitespaces-CodePudding

I don't want you to be able to save a certain phone number regardless of whether you write it with whitespaces or not. The number is entered in an input field and transmitted to the database via a send button. Is there a validation rule for this or another possibility?

'number' => ['required', 'number', Rule::notIn('07911123456')],

For example, you shouldn't be able to enter either: '07911 123456', '079 11123456', '0791112 345 6'

I've already tried the regex rule(https://laravel.com/docs/6.x/validation#rule-regex), but it doesn't do exactly what I want. I want to allow whitespaces but the number that is not allowed should still not be allowed no matter how many whitespaces are included.

Before You post it to server You could remove whites-spaces:

number = '07911 123456';
number = number.replace(/\s/g, '');
var intNumber = parse.Int(number);

For php part You could use:

$number = preg_replace('/\s /', '', $number);

CodePudding user response：

you can trim the name input before validating it ....

in you request:

 public function rules()
    {
      $this->merge(['number'=>str_replace(' ', '',$this->input('number'))]);

       return [
        'number' => ['required', 'number', Rule::notIn(['07911123456'])],
        ];
}

Try this solution

if number filed is not array

<?php 

$validator = [   
    'number' => [
        'required',
        'regex:/^[0-9][0-9\s] [0-9]$/',  // check number with white space
        function ($attribute, $value, $fail) {
            if ('07911123456' === \preg_replace('/\s /', '', $value)) {
                $fail('Message fail');

                return false;
            }

            return true;
        }, 
    ],
// ... another rules
];

$validator = Validator::make($request->all(), $validator);

If number field is array

<?php


$validator = [
    'number' => [
        'required', 'array',
     ],
     'number.*' => [
        'regex:/^[0-9][0-9\s] [0-9]$/',  // check number with white space
        function ($attribute, $value, $fail) {
            if ('07911123456' === \preg_replace('/\s /', '', $value)) {
                $fail('Message fail');

                return false;
            }

            return true;
        },
     ],
// ... another rules
];

$validator = Validator::make($request->all(), $validator);
