How to fetch data between two fields in CodeIgniter?

To fetch data between two fields in CodeIgniter, you can write a custom query using CodeIgniter's query builder class.

Here is an example of how you can fetch data between two fields in a CodeIgniter model:

1
2
3
4
5
6
7
8

public function get_data_between_fields($field1, $field2) {
    $this->db->select('*');
    $this->db->from('your_table_name');
    $this->db->where("$field1 BETWEEN $field2");
    $query = $this->db->get();
    
    return $query->result();
}

In this example, $field1 and $field2 are the names of the two fields you want to fetch data between. Replace 'your_table_name' with the actual name of the table in your database.

You can then call this method in your controller to fetch the data between the two fields:

1
2

$this->load->model('your_model_name');
$data = $this->your_model_name->get_data_between_fields('field1', 'field2');

Make sure to adjust the field names and table name according to your database structure.

What is the significance of retrieving data between two specific fields in CodeIgniter?

Retrieving data between two specific fields in CodeIgniter is significant because it allows you to filter and narrow down the results based on specific criteria.
