Running multiple queries in model in codeigniter

问题

I have this code in model in codeigniter:

<?php
Class Mymodel Extends CI_Model
{
    function __construct()
    {
        parent::__construct();
    }

    function search($textinput)
    {
        $street = "select street from dataSearch;";
        $stripNameWOSpace = "select stripNameWOSpace FROM dataSearch;";
        $vowels = array('a','e','i','o','u',';','/','-', ' ');
        $string = strtolower($textinput);
        $strippedVowels = mysql_real_escape_string(str_replace($vowels, '', $string));
            $this->db->query("select dataSearch.id,
                dataSearch.name,
                dataSearch.street,
                dataSearch.city,
                dataSearch.lat,
                dataSearch.lng,
                category.asiatype from dataSearch join category on dataSearch.cat = category.id
                where dataSearch.street like '%".$textinput."%'");
            $this->db->query("select dataSearch.id,
                dataSearch.name,
                dataSearch.street,
                dataSearch.city,
                dataSearch.lat,
                dataSearch.lng,
                category.asiatype from dataSearch join category on dataSearch.cat = category.id
                where dataSearch.stripNameWOSpace like '%".$strippedVowels."%'");
            $query = $this->db->get();
            $query->result();

    }
}
?>

I just want to execute multiple queries. You notice in where statement the two have different condition. I just want to get the result for the two queries. I try the switch statement to execute both queries and it is not working. Help me.

You can set the query to a variable to do your things with each query.

Like this:

Class Mymodel Extends CI_Model
{
    function __construct()
    {
        parent::__construct();
    }

    function search($textinput) {
        $query1 = $this->db->query("YOUR QUERY");
        $query2 = $this->db->query("YOUR SECOND QUERY");

        $result1 = $query1->result();
        $result2 = $query2->result();

        return array_merge($result1, $result2); // If you want to merge both results
    }
}

In your controller:

$this->load->model('Mymodel');
$searchresult = $this->Mymodel->search($textinput);

For more information, you should read CodeIgniter User Guide - Model

回答2:

I know...old, was looking for something else when I saw something that could be done better. the two select statements are identical except for the where statement. you can use "OR" to combine the two WHERE statements. use "DISTINCT" to avoid duplicate entries. "UNION" should be used if you really want duplicate entries.
