query builder like with wildcard in the middle

Code:

SELECT * FROM table WHERE column LIKE 'some%thing'

3rd parameter
after = 'some%thing%'
before = '%some%thing'
both (or leave empty) = '%some%thing%'

but how with 'some%thing' ??

i just can use this:

Code:

SELECT * FROM table WHERE column LIKE '%" .$this->db->escape_like_str($search)."%' ESCAPE '!

can i use query builder to produce LIKE clause with wildcare in the middle?

You can use or_like query.

$alpha = $searchData['alpha'];
$where = "`title` LIKE '$alpha%'";
$this->db->where($where);

The query builder works differently:

PHP Code:

$this->db->like('column', $alpha, 'both'); 
$query = $this->db->get('table');

if ($query->num_rows() > 0) {
   $records = $query->result();
}
else {
   $records = NULL;
} 


You can use the existing 3rd and 4th parameters to like():

Code:

$this->db->like('column', 'some%thing', 'none', FALSE)

3rd param prevents prefix/postfix additional wildcard chars, 4th param prevents escaping embedded wildcard chars.

@plonknimbuzz,

...or you could use query binding ( https://www.codeigniter.com/user_guide/d...y-bindings ). Query binding automatically escapes the variable.

$sql = "SELECT * FROM table WHERE column LIKE '%?%' ESCAPE!";
$this->db->query($sql, $value));
