I have the following regex expression in PHP
/^(\d{4}-(\d{4})?)$/
I want match only a string like this
1998-
1998-2015
I am using it in laravel validation like so:
'release_year' => 'required|regex:/^(\d{4}-(\d{4})?)$/'
Nothing else should match and number should be a 4 digit number. But it doesn't seem to be working.
分享 In Laravel documentation:
regex:patternThe field under validation must match the given regular expression.
Note: When using the regex pattern, it may be necessary to specify rules in an array instead of using pipe delimiters, especially if the regular expression contains a pipe character.
Try this:
'release_year' => array('required', 'regex:/^(\d{4}-(\d{4})?)$/')
