Query for If search value equals both rows? - php

Question

I have this code pretty much like a search engine within the database for peoples names.
if (isset($_POST['submit'])){
$keyword = $_POST['stats'];
$orderby = $_POST['orderby'];
if (!empty($_POST['stats'])) {
$getStats = $db->query("SELECT * FROM `stats` WHERE
`lastname` LIKE '%$keyword%' OR `firstname` LIKE '%$keyword%' OR
`nickname` LIKE '%$keyword%' ORDER BY `$orderby`
DESC");
This then prints the results back into a table, I thought the table code wasn't necessary and too long.
The above query works for if I search just the last name or just the first name, or nickname
but if there is for example a user in the database with the name, John Smith
so
Firstname: John
Lastname: Smith
If just searched 'John' he would be printed into the table, which is good and same if I just searched 'Smith'
But if I search 'John Smith' he would not be printed into the table.
How can I change this query so that this will happen, I have tried this:
$getStats = $db->query("SELECT * FROM `stats` WHERE
`firstname`, `lastname` = '$keyword' OR `lastname` LIKE '%$keyword%' OR `firstname` LIKE '%$keyword%' OR
`nickname` LIKE '%$keyword%' ORDER BY `$orderby`
DESC");

Answer 1

WHERE CONCAT(firstname, ' ', lastname) LIKE %$keyword%
Also you should be binding parameters rather than directly interpolating user input into the query string, your current code is vulnerable to SQL injection.

Answer 2

$keyword = str_replace(" ", "%", $keyword);

Answer 3

You can try REGEXP:
$keyword = $db->real_escape_string($_POST['stats']); // escape data
$orderby = $db->real_escape_string($_POST['orderby']); // escape data
$keyword = implode("|", explode(" ", $keyword));
$getStats = $db->query("SELECT * FROM stats
WHERE firstname REGEXP '$keyword'
OR lastname REGEXP '$keyword'
OR nickname REGEXP '$keyword'
ORDER BY $orderby DESC");

Answer 4

try this
$sql = "SELECT *
FROM stats
WHERE
firstname LIKE '%$keyword%'
OR lastname LIKE '%$keyword%'
OR CONCAT_WS(' ',firstname,lastname,) LIKE '%$keyword%'
OR CONCAT_WS(' ',lastname,firstname) LIKE '%$keyword%'
OR nickname LIKE '%$keyword%'
ORDER BY $orderby DESC";
