首先,请考虑我是CodeIgniter的新手。
当我做print_r($info);
内部控制器:Array ( [message] => Usu. [value] => 1 )
内部视图:
A PHP Error was encountered
Severity: Notice
Message: Undefined variable: info
Filename: views/administration.php
Line Number: 4
在我的控制器内部,我试图改变以下几行:
$this->load->view('administration', (object) $info);
$this->load->view('administration', $info);
$this->load->view('administration');
控制器:
<?php
if (!defined('BASEPATH'))
exit('No direct script access allowed');
class Admin extends CI_Controller {
function __construct() {
parent::__construct();
$this->load->library('session');
}
function index() {
$this->load->model('setup_model');
$this->setup_model->initialisation();
//Load admin model
$this->load->model('administration_model');
//Afficher l'administration
$info = $this->administration_model->log();
print_r($info); // Array ( [message] => Usu. [value] => 1 )
$this->load->view('administration', $info);
}
}
查看:
<?php
$this->load->helper('form');
$title = "Administration";
$error = $info["message"];
$output = "";
if($info["value"]){
$noticeClass = "goodNotice";
}else{
$noticeClass = "errorNotice";
$output .= form_open('admin');
$output .= '<h5>Username</h5>';
$output .= '<input type="text" name="username" value="" size="50" />';
$output .= '<h5>Password</h5>';
$output .= '<input type="password" name="password" value="" size="50" />';
$output .= '<div><input type="submit" value="Submit" /></div>';
$output .= '</form>';
}
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title><?php echo $title; ?></title>
</head>
<body>
<h3 class='<?php echo $noticeClass ?>'><?php echo $error; ?> </h3>
<?php echo $output; ?>
</body>
</html>
答案 0 :(得分:2)
Codeigninter在加载视图时会展开$info
变量。它应该是一个数组:
$info = array('key' => 'value');
然后在您看来,您可以echo $key
输出value
。
