validate integer starting with 0

This can help. StackOverflow
So from there just create new validate func which check for string is integer or just convert it to integer
(int) "03"

Regex validation rule ?

'birth_date_day' => 'required|regex:[0-9]+|between:1,31'

@pmall I think question is check string is integer

Yes so I check if this string looks like an integer with leading zeros ;)

I am having this error

preg_match(): Unknown modifier '+'

When I try using @pmall answer.

@CANFONE - 'birth_date_day' => 'required|regex:/[0-9]+/|between:1,31'

Sorry, I know this is an old thread but I found this in google and none of the above solutions worked. I guess that if I found it, others will too.

@bryanscott suggestion expected the value to be between 1 and 31 characters long, not between 1 and 31 numerically. This may have worked on older versions.

The solution I found that worked in Laravel 8 was using the 'numeric' validation rule. This may have not existed when this post was started.

'dob_day' => 'required|numeric|between:1,31'

This works with values like 5 and 05, but expects the value to be between the intval of 1 and 31 numerically.

My full code:

'dob_day' => 'required|numeric|between:1,31',

'dob_month' => 'required|numeric|between:1,12',

'dob_year' => 'required|numeric|between:1900,2022',

I find this GEM:

https://laravel.com/docs/9.x/validation#rule-doesnt-start-with https://laravel.com/docs/9.x/validation#rule-doesnt-end-with

Doesn't start, and doesn't end with... then the value you want

I Love Laravel :) and laracast forum
