我坚持为我的代码点火器搜索表单编写视图，需要使用get..
我目前有这个
控制器
<?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", $data);
}
型
class Messages_model extends CI_Model{
function searchMessages($string){
$this->load->database();
$query = $this->db->query("SELECT * FROM messages WHERE text LIKE '%$string%'");
return $query->result();
}
视图
<!DOCTYPE html>
<html>
<style>
</style>
<head>
<title></title>
</head>
<body>
<form action="<?php echo site_url('Search/doSearch');?>" method = "get">
<input type="text" name = "keyword"/>
<input type="submit" value = "Search" />
</form>
</div>
</body>
</html>
谁能帮我显示搜索字符串
首先，转到应用程序/配置/配置.php并找到$config['allow_get_array']并确保它设置为 TRUE 。
然后在您的控制器中，您将拥有如下所示的内容：
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);
}
请注意，此处的字符串没有进行任何验证，因此您需要添加自己的验证。
希望这有帮助！

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>
控制器方法：
公共函数 doSearch（） { $this->负载>模型（"Messages_model"）;
if ($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);
}
