Codeigniter: Weird behaviour of $this->db->like()

Question

I\'ve written a simple query for searching a keyword in the database.

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

$th         


        

Answer 1

Use the escape_like_str() method.

The escape_like_str() method should be used when strings are to be used in LIKE conditions so that LIKE wildcards %, _ in the string are also properly escaped. It cannot automatically add the ESCAPE ! condition for you, and so you’ll have to manually do that.

Hope it helps.

$keyword = "keyword sample"; 
$sql = "SELECT id FROM table WHERE column LIKE '%" .
$this->db->escape_like_str($keyword)."%' ESCAPE '!'";
