Searching with Laravel or_where() - php

Question

My goal is to search for a first and last name using Laravel. As the code is written, it searches for a First Name or Last Name, what I would like to do is get it to search for both First Name and Last Name. How would I accomplish this?
PHP - Search Statement
public function search($search_input) {
$response = DB::table(self::$table)
->select(array(
'ID',
'User_ID',
'Signup_Date',
'First_Name',
'Last_Name',
DB::raw('CONCAT(First_Name," ",Last_Name) AS Name')
))
->where('First_Name', 'LIKE', '%'.$search_input.'%')
->or_where('Last_Name', 'LIKE', '%'.$search_input.'%')
->where_not_null('User_ID')
->order_by('Signup_Date', 'desc')
->get();
return $response;
}
EDIT: I forgot to include we are using Laravel 3. https://laravel3.veliovgroup.com/docs/database/fluent

Answer 1

As I understand, your query condition is
(First_Name LIKE "%xx%" OR Last_name LIKE "%xx%") AND User_id IS NOT NULL
You should modify your query as below to use nested where clauses:
public function search($search_input) {
$response = DB::table(self::$table)
->select(array(
'ID',
'User_ID',
'Signup_Date',
'First_Name',
'Last_Name',
DB::raw('CONCAT(First_Name," ",Last_Name) AS Name')
))
->where(function($query) use ($search_input) {
$query->where('First_Name', 'LIKE', '%'.$search_input.'%')
->or_where('Last_Name', 'LIKE', '%'.$search_input.'%');
}
->where_not_null('User_ID')
->order_by('Signup_Date', 'desc')
->get();
return $response;
}

If you have it search both first name and last name, then I doubt it would return results. Because it would imply the search query would have to match a record where the input is like the first name and like the last name. I think what you are actually after is more of a compound search. As you have the selects in your query, you might be able to do the following instead.
public function search($search_input) {
$response = DB::table(self::$table)
->select(array(
'ID',
'User_ID',
'Signup_Date',
'First_Name',
'Last_Name',
DB::raw('CONCAT(First_Name," ",Last_Name) AS Name')
))
->where('Name', 'LIKE', '%'.$search_input.'%')
->where_not_null('User_ID')
->order_by('Signup_Date', 'desc')
->get();
return $response;
}
This should work because Name is being set by the CONCAT function.
