Instead of a regex you can use alpha_num.
To solve with a regex it will look something like this: 'regex:/[a-zA-Z0-9]+/', {1} has no limiting effect here it will just be added to the character group.

regex in validator rules
hello,
Something is wrong with my regex in Laravel a username should only include uppercase letters, lowercase letters and numbers.
public function rules()
{
return [
'name' => [
'required',
'unique:users,name',
'min:10',
'regex:/[a-z{1}A-Z{1}0-9{1}]+/',
]
];
}
According to this site it actually should work: https://regexr.com/
hope you guys could help me again
thanks Amit

You need to be testing the entire string, also your regexp is needlessly verbose:
'regex:/^[a-zA-Z0-9]+$/',
If you can tolerate underscore (_) in the username, then \w would be neater as a rule

alpha_num works. I actually also tried:
'regex:/^[a-zA-Z0-9]+$/',
and many other versions. now I have many invalid entries in my database and i can't delete them because of "safe mode"
