Laravel - Validation - Rule Regex
The field under validation must match the given regular expression.
Internally, this rule uses the PHP preg_match
function. The pattern specified should obey the same formatting required by preg_match
and thus also include valid delimiters. For example: 'email' => 'regex:/^[email protected]+$/i'
.
When using theregex
/not_regex
patterns, it may be necessary to specify rules in an array instead of using|
delimiters, especially if the regular expression contains a|
character.
