I wrote an article before about how to extend ZF under ZF0.6 version. This should be said to be a similar article, but the environment is changed to ZF1.0RC1 version.

Before starting the ZF extension, it is recommended to read some command specifications in the ZF manual (recommended by ZF), and we hope that readers will have a better understanding of ZF. If not, you can first go to the ZF version of PHPCHIAN to learn more, or go to phpeye to find relevant information.

ZF’s validator provides powerful verification functions, but it is still too cumbersome in actual operation. For example, to verify emails, ZF’s code is as follows

require_once 'Zend/Validate/EmailAddress.php'; 🎜>if ($validator->isValid($email)) {
// email appears to be valid
} else {
// email is invalid; print the reasons
foreach ($ validator->getMessages() as $message) {
echo "$messagen";
}
}
?>

Have you noticed it? It’s still very similar. We don’t know. Use ZF's verification method. It’s just that ZF helped us encapsulate the details of email verification. So how do we simplify it to this effect? (The following is my extended calling method)

$validate = new Phpbean_Validate();
$validate -> set_breakOnFailure(false);
$validate - > add('email',new Zend_Validate_EmailAddress(),'The email address is incorrect!');
$validate -> add('username',new Zend_Validate_StringLength(3,15),'The username length must be within Between 3 and 15! '%value%' does not meet the conditions'); ');
$validate -> add('password',new Phpbean_Validate_isEqual($_POST['repassword']),'Two input passwords do not match');
$authcode = new Phpbean_Img_Code();
$validate -> add('yanxue8_authcode',new Phpbean_Validate_isEqual($authcode->authcode($_POST['yanxue8_authcode_mdcode'],'DECODE')),'Verification code does not match!');
if( !$validate -> validator($_POST) ){
error_page('Registration failed',$validate->getMessageText()); > Using the above method, on the one hand, the code is clear, and on the other hand, it also facilitates consistent error handling. So how to do this?
The key is the Phpbean_Validate class.
In fact, it is very simple to implement. The Phpbean_Validate::add() method adds verification rules one by one. Then call Phpbean_Validate::validator() to verify and it's OK.
The specific implementation steps are as follows:
First, add a phpbean folder in the same level directory of zend, and then add a Validator.php file in it.
Then, add the definition of the Phpbean_Validate class to the validator.php file. Note (you can change it to your own file name and path name, but be sure to keep it consistent with the name of the class).
Here, I give the implementation process of my Phpbean_Validate class for reference only.

class Phpbean_Validate{

    protected $_fileds =array();

    protected $_message = array();

    protected $_breakOnFailure = true;

    public function set_breakOnFailure($value){
        $this->_breakOnFailure = $value;
    }

    public function add($key,$validate,$message='',$breakOnFailure=''){
        if( empty($breakOnFailure) ) $breakOnFailure = $this->_breakOnFailure;
        $this->_fileds[] = array($key,$validate,$message,$breakOnFailure);
        return $this;
    }

    public function validator($array = array()){
        if(empty($array)) $array = $_POST;
        if (is_array($this->_fileds)) {
            foreach ($this->_fileds as $filed){
                list($key,$validate,$message,$breakOnFailure) = $filed;

                if(empty($key)){
                    if(!$validate){
                        $this->_message[][] = $message;
                        if($breakOnFailure) break;
                    }
                    continue;
                }

                if(!empty($message)) $validate->setMessage($message);
                if( !$validate->isValid($array[$key]) ){
                    $this->_message[$key][] = $validate->getMessages();
                    if($breakOnFailure) break;
                }
            }
            if(!empty($this->_message))return false;
            return true;
        }
        return true;
    }

    public function getMessage(){
        return $this->_message;
    }
    public function getMessageText(){
        $str = '';
        foreach ($this->_message as $ms){
            foreach ($ms as $m) $str .= $m[0]."n";
        }
        return $str;
    }
}
?>

   另外你还可以直接扩展一些验证规则类。I’ll talk about it in detail in the next article.
