Category:Plugin -> Data Conversion
The following plugin will generate a tab-delimited file, and feed it to the client as an Excel file.
$this->load->plugin('to_excel');
$this->db->use_table('tablename');
$this->db->select('field1', 'field2');
// run joins, order by, where, or anything else here
$query = $this->db->get();
to_excel($query, ['filename']); // filename is optional, without it, the plugin will default to 'exceloutput'
So you could run:
to_excel($query, 'myfile'); // outputs myfile.xls
to_excel($query); // outputs exceloutput.xls
// you could also use a model here
to_excel($this->model_name->functioncall());
