本文介绍了如何在CodeIgniter中使用Captcha插件的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我按照这个网页,代码无法像我在项目中一样工作。我试图找到其他教程如何执行我需要的,但是,它不工作,因为它应该在我的项目。有没有人能够指导我到一个教程,以详细的方式解释如何正确地使用Captcha插件在CodeIgniter?



控制器

  ?php 
class Prova extends Controller
{
function prova()
{
parent :: Controller();

$ this - >负载 - > plugin('captcha');

$ this-> load-> library('validation');
$ rules ['user'] =必需;
$ rules ['captcha'] =必需| callback_captcha_check;
$ this-> validation-> set_rules($ rules);

$ fields ['user'] ='Username';
$ fields ['captcha'] ='codice';
$ this-> validation-> set_fields($ fields);
if($ this-> validation-> run()== FALSE)
{
$ expiration = time() //两小时限制
$ this-> db-> query(DELETE FROM captcha WHERE captcha_time<。$ expiration);
$ vals = array(
//'word'=>'随机字',
'img_path'=>'./tmp/captcha/',
' img_url'=> base_url()。'tmp / captcha /',
'font_path'=>'./system/fonts/texb.ttf',
'img_width'=>'100 ',
'img_height'=>'30',
'expiration'=>'3600'
);

$ cap = $ this-> captcha-> create_captcha($ vals);
//
$ dati ['image'] = $ cap ['image'];
// mette nel db
$ data = array(
'captcha_id'=>'',
'captcha_time'=> $ cap ['time'],
'ip_address'=> $ this-> input-> ip_address(),
'word'=> $ cap ['word']
);

$ query = $ this-> db-> insert_string('captcha',$ data);
$ this-> db-> query($ query);
$ this-> load-> view('captcha',$ data);
} else {
echoCaptcha is not be made;
}
return $ cap ['image'];
}

函数captcha_check()
{
//然后查看是否存在验证码:
$ exp = time() - 600;
$ sql =SELECT COUNT(*)AS count FROM captcha WHERE word =?AND ip_address =?AND captcha_time>?
$ binds = array($ this-> input-> post('captcha'),$ this-> input-> ip_address(),$ exp);
$ query = $ this-> db-> query($ sql,$ binds);
$ row = $ query-> row();

if($ row-> count == 0)
{
$ this-> validation-> set_message('_ captcha_check','Codice di controllo non valido ');
return FALSE;
} else {
return TRUE;
}

}
}

// -------- -------------------------------------------------- --------------

说明:

使用以下命令加载插件:

$ this-> load-> plugin('captcha');

载入后,您可以生成如下所示的验证码:

$ vals = array(
'word'=>'随机字',
'img_path'=>'./captcha/',
'img_url'=>'http://example.com/captcha/',
'font_path'=>'./system /fonts/texb.ttf',
'img_width'=>'150',
'img_height'=> 30,
'expiration'=> 7200
) ;

$ cap = create_captcha($ vals);
echo $ cap ['image'];


注意:

captcha功能需要GD图像库。

只需要img_path和img_url。

如果不提供word,函数将生成一个随机的
ASCII字符串。你可以把你自己的词库放在一起,你可以从中随机抽取


如果不指定TRUE TYPE字体的路径,将使用本机丑陋的GD
字体。

captcha文件夹必须是可写的(666或777)

过期(以秒为单位)表示图像将保留
多长时间其前的captcha文件夹将被删除。默认
是两个小时。

返回数据

create_captcha()函数返回一个具有这些数据的关联数组:

[array]

'image'=>图片标记
'time'=> TIMESTAMP(微时)
'word'=  CAPTCHA WORD


image是实际的图片标记:
< img src =http://example.com/captcha/12345.jpgwidth =140height =50/>

time是用作图像名称而没有文件
扩展名的微时间戳。它将是一个这样的数字:1139612155.3422

字是验证码图像中出现的字,如果不是
提供给函数,将是一个随机字符串。


添加数据库

为了使captcha功能防止某人发布,您将需要
来添加从create_captcha )函数到您的数据库。
然后,当用户提交表单中的数据时,您将需要验证
数据库中存在的数据并且未过期。

这是一个表原型:

CREATE TABLE验证码(
captcha_id bigint(13)unsigned NOT NULL auto_increment,
captcha_time int NOT NULL,
ip_address varchar(16)default'0'NOT NULL,
word varchar(20)NOT NULL,
PRIMARY KEY`captcha_id` KEY`word`(`word`)



下面是一个使用DB的例子。

在显示验证码的页面上,您将看到以下内容:

$ this-> load-> plugin('captcha');
$ vals = array(
'img_path'=>'./captcha/',
'img_url'=>'http://example.com/captcha/'
);

$ cap = create_captcha($ vals);

$ data = array(
'captcha_id'=>'',
'captcha_time'=> $ cap ['time'],
'ip_address '=> $ this-> input-> ip_address(),
'word'=> $ cap ['word']


$ query = $ this-> db-> insert_string('captcha',$ data);
$ this-> db-> query($ query);

echo'提交您在下面看到的词:';
echo $ cap ['image'];
echo'< input type =textname =captchavalue =/>';


然后,在接受提交的页面上你会有这样的:

//首先,删除旧的验证码
$ expiration = time() - 7200; //两小时限制
$ DB-> query(DELETE FROM captcha WHERE captcha_time<。$ expiration);

//然后查看是否存在验证码:
$ sql =SELECT COUNT(*)AS count FROM captcha WHERE word =?AND ip_address =?AND date>?
$ binds = array($ _ POST ['captcha'],$ this-> input-> ip_address(),$ expiration);
$ query = $ this-> db-> query($ sql,$ binds);
$ row = $ query-> row();

if($ row-> count == 0)
{
echo您必须提交图像中出现的词;
}

I followed this page, and the code is not working as it should in my project. I've tried to find other tutorial on how to execute what I need, however, it does not work as it should in my project either. Is anyone able to direct me to a tutorial that explains in a detailed fashion on how to use Captcha plug-in properly in CodeIgniter?

// ------------------------------------------------------------------------

/*
Instructions:

Load the plugin using:

    $this->load->plugin('captcha');

Once loaded you can generate a captcha like this:

    $vals = array(
                    'word'       => 'Random word',
                    'img_path'   => './captcha/',
                    'img_url'    => 'http://example.com/captcha/',
                    'font_path'  => './system/fonts/texb.ttf',
                    'img_width'  => '150',
                    'img_height' => 30,
                    'expiration' => 7200
                );

    $cap = create_captcha($vals);
    echo $cap['image'];


NOTES:

    The captcha function requires the GD image library.

    Only the img_path and img_url are required.

    If a "word" is not supplied, the function will generate a random
    ASCII string.  You might put together your own word library that
    you can draw randomly from.

    If you do not specify a path to a TRUE TYPE font, the native ugly GD
    font will be used.

    The "captcha" folder must be writable (666, or 777)

    The "expiration" (in seconds) signifies how long an image will
    remain in the captcha folder before it will be deleted.  The default
    is two hours.

RETURNED DATA

The create_captcha() function returns an associative array with this data:

  [array]
  (
    'image' => IMAGE TAG
    'time'  => TIMESTAMP (in microtime)
    'word'  => CAPTCHA WORD
  )

The "image" is the actual image tag:
<img src="http://example.com/captcha/12345.jpg" width="140" height="50" />

The "time" is the micro timestamp used as the image name without the file
extension.  It will be a number like this:  1139612155.3422

The "word" is the word that appears in the captcha image, which if not
supplied to the function, will be a random string.


ADDING A DATABASE

In order for the captcha function to prevent someone from posting, you will need
to add the information returned from create_captcha() function to your database.
Then, when the data from the form is submitted by the user you will need to verify
that the data exists in the database and has not expired.

Here is a table prototype:

    CREATE TABLE captcha (
     captcha_id bigint(13) unsigned NOT NULL auto_increment,
     captcha_time int(10) unsigned NOT NULL,
     ip_address varchar(16) default '0' NOT NULL,
     word varchar(20) NOT NULL,
     PRIMARY KEY `captcha_id` (`captcha_id`),
     KEY `word` (`word`)
    )


Here is an example of usage with a DB.

On the page where the captcha will be shown you'll have something like this:

    $this->load->plugin('captcha');
    $vals = array(
                    'img_path'   => './captcha/',
                    'img_url'    => 'http://example.com/captcha/'
                );

    $cap = create_captcha($vals);

    $data = array(
                    'captcha_id'    => '',
                    'captcha_time'  => $cap['time'],
                    'ip_address'    => $this->input->ip_address(),
                    'word'          => $cap['word']
                );

    $query = $this->db->insert_string('captcha', $data);
    $this->db->query($query);

    echo 'Submit the word you see below:';
    echo $cap['image'];
    echo '<input type="text" name="captcha" value="" />';


Then, on the page that accepts the submission you'll have something like this:

    // First, delete old captchas
    $expiration = time()-7200; // Two hour limit
    $DB->query("DELETE FROM captcha WHERE captcha_time < ".$expiration);        

    // Then see if a captcha exists:
    $sql = "SELECT COUNT(*) AS count FROM captcha WHERE word = ? AND ip_address = ? AND date > ?";
    $binds = array($_POST['captcha'], $this->input->ip_address(), $expiration);
    $query = $this->db->query($sql, $binds);
    $row = $query->row();

    if ($row->count == 0)
    {
        echo "You must submit the word that appears in the image";
    }
