我的CodeIgniter验证码没有生成,所以我无法在我的视图中显示它
控制器
public function login() {
$this->load->helper('captcha');
$this->form_validation->set_rules($this->login_rules);
$userCaptcha = set_value('captcha');
$word = $this->session->userdata('captchaWord');
if($this->form_validation->run() == TRUE && strcmp(strtoupper($userCaptcha),strtoupper($word)) == 0) {
$this->session->unset_userdata('captchaWord');
$username = $this->input->post('username');
$password = $this->input->post('password');
if(!$this->autentifikasi->login($username,$password)) {
$this->session->set_flashdata('pesan', '<div class="error">Login gagal</div>');
redirect(site_url('user/login'));
} else {
$this->session->set_flashdata('pesan', '<div class="sukses">Anda telah berhasil login, selamat berbelanja.</div>');
redirect(site_url('user/login'));
}
}
$original_string = array_merge(range(0,9), range('a','z'), range('A', 'Z'));
$original_string = implode("", $original_string);
$captcha = substr(str_shuffle($original_string), 0, 6);
$vals = array(
'word' => $captcha,
'img_path' => './captcha/',
'img_url' => base_url().'user/login/',
'font_path' => './fonts/texb.ttf',
'img_width' => '150',
'img_height' => 30,
'expiration' => 3600
);
$cap = create_captcha($vals);
$data['image']= $cap['image'];
$this->session->set_userdata('captchaWord', $captcha);
$this->template->set_judul('PT. Columbindo Perdana')
->set_css('style')
->set_parsial('sidebar','sidebar_view',$this->data)
->set_parsial('topmenu','top_view',$this->data)
->render('user_login',$this->data);
}
查看
<?php if($this->session->flashdata('pesan')): ?>
<?php echo $this->session->flashdata('pesan'); ?>
<?php else:?>
<h2>Silakan Login</h2>
<?php if(@$error){echo @$error;} ?>
<?php echo validation_errors(); ?>
<br />
<?php echo form_open(site_url(uri_string()),'class="order"'); ?>
<?php echo form_label('Username'); ?>
<?php echo form_input('username'); ?>
<?php echo form_label('Password'); ?>
<?php echo form_password('password'); ?>
<?php echo form_label('Captcha'); ?>
<?php echo $image; ?>
<?php echo form_input('captcha'); ?>
<?php echo form_submit('submit','Login'); ?>
<?php echo form_close(); ?>

据我所知,我没有验证码文件夹或字体文件夹,是否仍然会在没有这2个文件夹的情况下自行生成?我已经尝试了从一些解决的问题,但它仍然无法正常工作。没有错误,但验证码图像没有出现。
请帮帮我。
答案 0 :(得分:4)
问题是您将$this->data
传递到视图,但是您要将生成的图像分配给$data
。所以你需要从
$data['image']= $cap['image'];
到
$this->data['image']= $cap['image'];
如果不起作用,请确保将图像保存到('img_path' => './captcha/'
)的验证码目录是可写的,可以是666或777.您可以对命令执行chmod 777 captcha/
线。还要确保在php.ini
