在Codeigniter中的模型中运行多个查询 [英] Running multiple queries in model in codeigniter

问题描述

我在codeigniter的模型中有以下代码：

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();

    }
}
?> 

我只想执行多个查询。您会在where语句中注意到两者具有不同的条件。我只想获取两个查询的结果。
我尝试使用switch语句执行两个查询，但它不起作用。帮帮我。

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.

推荐答案

您可以将查询设置为变量，以便对每个查询执行操作。

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

就像这样：

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
    }
}

在您的控制器：

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