我正在尝试使用 codeigniter 实现验证码功能。但它不显示验证码图像。
这是我的代码:
//控制器文件:captcha.php
<?php
class Captcha extends CI_Controller {
var $controller = "captcha";
var $viewContent = array();
public function __construct() {
parent::__construct();
$this->load->view('header');
}
/* Function To load captcha view file */
function list_captcha() {
// 加载验证码助手
$this->load->helper('captcha');
$data = array(
'img_path' => './captcha/',
'img_url' => 'localhost/demoProject/application/captcha/',
'img_width' => '150',
'img_height' => 24,
'border' => 0,
'expiration' => 7200
);
$captchaArr = create_captcha($data);
$this->viewContent['captchaArr'] = $captchaArr;
$this->viewContent['captchaWord'] = $captchaArr['word'];
//echo"<pre>"; print_r($captchaArr);exit;
$this->viewContent['refreshUrl'] = "localhost/
demoProject/" . $this->controller . "/list_" . $this->controller;
$this->load->view($this->controller, $this->viewContent);
$this->load->view('footer');
}
}
?>
//查看文件:captcha.php
<script>
$(document).ready(function(){
$("#captcha").blur(function(){
if($("#captcha").val()== '<?php echo $captchaWord; ?>'){
alert('Captcha match');
}else{
alert('Please enter same word like captcha image.');
}
});
});
</script>
<table>
<tr>
<td>
Captcha Image
</td>
<td style="text-align: center">
<?php echo $captchaArr['image']; ?><br>
</td>
</tr>
<tr>
<td>Enter the same code here </td>
<td style="text-align: center">
<?php
$data = array('name' => 'captcha', 'id' => 'captcha');
echo form_input($data);
?>
</td>
</tr>
<tr>
<td>Can't read the image?</td>
<td style="text-align: center"> <a href="<?php echo $refreshUrl; ?>">Refresh</a></td>
</tr>
</table>
我没有得到这段代码有什么问题......
