How to use like in where clause in Codeigniter?

@deron 

In Codeigniter, you can use the like() method in the where() clause of a database query to search for rows that match a certain pattern. Here's an example of how to use like() in a where() clause:

1

$this->db->like('column_name', 'pattern', 'before/after/both');

The column_name argument specifies the name of the column you want to search. The pattern argument specifies the pattern you want to match. The before/after/both argument is optional and specifies whether the pattern should be matched before, after, or both before and after the column value.

Here's an example of a complete query using like() in the where() clause:

1
2
3
4

$this->db->select('*');
$this->db->from('table_name');
$this->db->like('column_name', 'pattern', 'both');
$query = $this->db->get();

This would select all rows from the table_name table where the column_name column contains the pattern anywhere within it.

You can also use multiple like() clauses in the same where() clause by chaining them together like this:

1
2
3
4

$this->db->like('column_name1', 'pattern1', 'both');
$this->db->like('column_name2', 'pattern2', 'both');
$this->db->like('column_name3', 'pattern3', 'both');
$query = $this->db->get('table_name');

This would select rows from the table_name table where any of the specified columns contain the corresponding pattern.

In CodeIgniter, you can use the like() method in the where clause to perform a SQL LIKE query.

Here's an example of how to use like() in the where clause:

1
2
3
4

$this->db->select('*');
$this->db->from('table_name');
$this->db->like('column_name', 'search_string', 'both');
$query = $this->db->get();

In the above example:

• select('*') selects all columns from the table.
• from('table_name') specifies the name of the table you want to query.
• like('column_name', 'search_string', 'both') specifies the column name, search string, and the search type. The third parameter 'both' indicates that the search string can appear anywhere in the column value. You can also use 'before' or 'after' for different search types.
• $this->db->get() runs the query and returns the result set.

You can then iterate over the result set to retrieve the matching rows.
