PhpLaravelLaravel 5Laravel 5.2Laravel ValidationPhp Problem Overview
foo.blade.php
<input type="text" name="national-id" />
FooController.php
$rules = [
'national-id' => 'required|size:10|numeric'
];
the national-id field should contain 10 digits and I actually expected the code above to validate this , but instead It will check If the national-id exactly equals to 10 or not ...
how can I validate the length of a numeric field?
Php Solutions
Solution 1 - Php
In fact you don't need to use digits_between rule. You can use digits rule so according to documentation it will be enough to use:
$rules = [
'national-id' => 'required|digits:10'
];
without numeric rule because digits rule also verify if given value is numeric.
Solution 2 - Php
When using size on a number it will check if the number is equal to the size, on string, it will check the amount of characters, for number you should use :
'number' => 'required|numeric|digits_between:1,10'
Solution 3 - Php
In laravel the size validation on a field that's numeric will indicate the max integer it cannot be larger than.
Use digits_between:
'national-id' => 'required|digits_between:10,10|numeric'
