CodeIgniter使用get按字符串搜索

Question

I am stuck with writing View for my code igniter search form which need to use get.. 我坚持为我的代码点火器搜索表单编写View，这需要使用get ..

I currently have this 我目前有这个

Controller 控制者

<?php
class Search extends CI_Controller {
    function __construct(){

        parent::__construct();

    }
    public function index(){
        $this->load->view('Search');
    }
    public function doSearch()
{
    $this->load->model("Messages_model");

    if ($this->input->get('search') !== FALSE) {
        $data ['results'] = $this->Messages_model->searchMessages($this->input->get('search'));
    } else {
        $data['results'] = array();
    }

    $this->load->view("Search", $data);
}

Model 模型

class Messages_model extends CI_Model{
function searchMessages($string){
    $this->load->database();
    $query = $this->db->query("SELECT * FROM messages WHERE text  LIKE '%$string%'");
    return $query->result();
}

View 视图

<!DOCTYPE html>
<html>
<style>
 </style>

<head>
    <title></title>
</head>
<body>
<form action="<?php echo site_url('Search/doSearch');?>" method = "get">
    <input type="text" name = "keyword"/>
    <input type="submit" value = "Search" />
</form>

</div>
</body>
</html>

Can anyone help me out in getting search string displayed 任何人都可以帮助我显示搜索字符串

Firstly, go to application/config/config.php and find $config['allow_get_array'] and make sure it's set to TRUE . 首先，转到application / config / config.php并找到$config['allow_get_array']并确保将其设置为TRUE 。

Then in your controller you would have something like this: 然后在您的控制器中，您将得到以下内容：

public function search()
{
    $this->load->model("Messages_model");

    if ($this->input->get('search') !== FALSE) {
        $data ['results'] = $this->Messages_model->searchMessages($this->input->get('search'));

    } else {
        $data['results'] = array();
    }

    $this->load->view("Search", $data);
}

Please note that there isn't any validation happening on the string here so you will need to add your own. 请注意，这里的字符串没有任何验证，因此您需要添加自己的验证。

Hope this helps! 希望这可以帮助！

View file: 查看文件：

<!DOCTYPE html>
<html>
    <style>
    </style>

    <head>
        <title></title>
    </head>
    <body>
        <form action="<?php echo site_url('search/doSearch'); ?>" method = "get">
            <input type="text" name="keyword" value="<?php echo isset($search_value) ? $search_value : ''?>"/>
            <input type="submit" value="Search" />
        </form>

        <?php
        if ($search_passed && !empty($results)) {
            foreach ($results as $result) {
                //Code for displaying results
            }
        } elseif ($search_passed && empty($results)) {
            echo 'No results found!';
        }
        ?>

    </div>
</body>
</html>

Controller Method: 控制器方式：

public function doSearch() { $this->load->model("Messages_model"); 公共功能doSearch（）{$ this-> load-> model（“ Messages_model”）;

    if ($this->input->get('keyword') !== FALSE) {
        $data ['results'] = $this->Messages_model->searchMessages($this->input->get('keyword'));
        //Uncomment the line below to test
        // echo '<pre>'; print_r($data['results']);die('</pre>');
        $data['search_passed'] = TRUE;
        $data['search_value'] = $this->input->get('keyword');
    } else {
        $data['search_passed'] = FALSE;
        $data['results'] = array();
    }

    $this->load->view("Search", $data);
}
