Escape Wildcard Characters in get_filtering() method

[briansulzen]

Search values that contain '%' or '_' will not return results. From Code Igniter guides:

The escape_like_str() method uses ‘!’ (exclamation mark) to escape special characters for LIKE conditions. Because this method escapes partial strings that you would wrap in quotes yourself, it cannot automatically add the ESCAPE '!' condition for you, and so you’ll have to manually do that.

change

$sWhere .= $this->select[$mColArray[$i]['data']] . " LIKE '%" . $sSearch . "%' OR ";

to:

$sWhere .= $this->select[$mColArray[$i]['data']] . " LIKE '%" . $sSearch . "%' ESCAPE '!' OR ";

and

$sWhere .= $this->select[$this->columns[$i]] . " LIKE '%" . $sSearch . "%' OR ";

to:

$sWhere .= $this->select[$this->columns[$i]] . " LIKE '%" . $sSearch . "%' ESCAPE '!' OR ";
