How to do that this function would look for a row in table not by given name John but by inputed 'name' ?
public function validation($request)
{
return $this->validate($request, [
'name' => 'required|max:255',
'last_name' => 'required|max:255',
'code' => ['required',Rule::exists('users')->where(function ($query) {
$query->where('name', '=', 'John');
}), ],
]);
}
Check your param and change 'John' to request->name
public function validation(Request $request){
return $this->validate($request, [
'name' => 'required|max:255',
'last_name' => 'required|max:255',
'code' => [
'required',
Rule::exists('users')
->where('name', $request->name)
],
]);
}</div>
You have to use use keyword for this and pass the $request object inside this like
public function validation($request)
{
return $this->validate($request, [
'name' => 'required|max:255',
'last_name' => 'required|max:255',
'code' => ['required',Rule::exists('users')->where(function ($query) use ($request) {
$query->where('name', '=', $request->name);
}), ],
]);
}
or, you can use like this without passing a callback function in where as
public function validation($request)
{
return $this->validate($request, [
'name' => 'required|max:255',
'last_name' => 'required|max:255',
'code' => array('required',Rule::exists('users')->where('name', '=', $request->name);),
]);
}
