Zend Framework Common Calibrator _php Example

The example of this article describes the common calibrator for the Zend Framework. Share to everyone for your reference, specific as follows:

Date Day Validator

Code:

<?php
require_once ' zend/validate/date.php ';
function C_date ($date) {
  $validator = new Zend_validate_date ();
  The date format entered by the IF ($validator->isvalid ($date)) {
    echo: ";
    echo $date. " Effective! <p> ";
  } else{
    echo "Enter the date format:";
    echo $date. " Invalid! <p> ";
  }
}
$date 1 = "2008-02-15";
$date 2 = "2008-02-31";
$date 3 = "02-15-2008";
C_date ($date 1);
C_date ($date 2);
C_date ($date 3);

Results:

Date format entered: 2008-02-15 effective!

Date format entered: 2008-02-31 invalid!

Date format entered: 02-15-2008 invalid!

Public Function IsValid ($value) {if!is_string ($value) &&!is_int ($value) &&!is_float ($value) ;&!is_array ($value) &&! ($value instanceof Zend_date))
      {$this->_error (self::invalid);
    return false;
    $this->_setvalue ($value); if ($this->_format!== null) | | ($this->_locale!== null) | |
       Is_array ($value) | |
      $value instanceof zend_date) {require_once ' zend/date.php '; if (! 
          Zend_date::isdate ($value, $this->_format, $this->_locale)) {if ($this->_checkformat ($value) = = False) {
        $this->_error (Self::falseformat);
        else {$this->_error (self::invalid_date);
      return false;
        } else {if (!preg_match ('/^\d{4}-\d{2}-\d{2}$/', $value)) {$this->_format = ' yyyy-mm-dd ';
        $this->_error (Self::falseformat);
        $this->_format = null;
      return false; List ($year, $month, $day= sscanf ($value, '%d-%d-%d ');
        if (!checkdate ($month, $day, $year)) {$this->_error (self::invalid_date);
      return false;
} return true;

 }

Inarray Array contains validator

Returns true if the content is contained in the array, or false.

Code:

<?php
require_once ' zend/validate/inarray.php ';
function C_array ($n) {
  $temp = array ("Beijing", "Shanghai", "Tianjin", "Chongqing");
  $validator = new Zend_validate_inarray ($temp);
  if ($validator->isvalid ($n)) {
    echo "specifies:";
    echo $n. ", existing in the specified array! <p> ";
  } else{
    echo "The specified content:";
    echo $n. ", does not exist in the specified array! <p> ";
  }
}
$city 1 = "Beijing";
$city 2 = "Chongqing";
$city 3 = "Zhengzhou";
C_array ($city 1);
C_array ($city 2);
C_array ($city 3);

Results:

Content specified: Beijing, exists in the specified array!

Specified: Chongqing, which exists in the specified array!

Content specified: Zhengzhou, does not exist in the specified array!

Regex Regular Matching Checker

By using regular expressions, coupled with the rational use of the school's detector, almost all of the validation rules can be implemented.

Code:

<?php
require_once "zend/validate.php";
function C_rege ($v) {
  $pattern = array ("/ab{2,}/");
  if (Zend_validate::is ($v, Regex, $pattern)) {
    echo <font color=\ "#006600 \" > Specified content: ";
    echo $v. " <p> conform to the defined formal rules! </font> ";
    echo "<p>";
  } else{
    echo "<font color=\" #ff0000 \ "> Specified content:";
    echo $v. " <p> does not conform to the defined formal rules! </font> ";
    echo "<p>";
  }
}
$temp 1 = "AB";
$temp 2 = "ABB";
$temp 3 = "ABBB";
C_rege ($temp 1);
C_rege ($temp 2);
C_rege ($temp 3);

Results:

Content specified: AB

Formal rules that do not conform to the definition!

Content specified: ABB

Conform to the formal rules of the definition!

Content specified: ABBB

Conform to the formal rules of the definition!

Comments:

Public function __construct ($pattern)
{
    if ($pattern instanceof zend_config) {
      $pattern = $pattern-> ToArray ();
    }
    if (Is_array ($pattern)) {
      if (array_key_exists (' pattern ', $pattern)) {
        $pattern = $pattern [' pattern '];
      } else {
        require_once ' zend/validate/exception.php ';
        throw new Zend_validate_exception ("Missing option ' pattern ');
      }
    $this->setpattern ($pattern);
}

constructor to initialize the private property,

Public Function IsValid ($value)
{
    if!is_string ($value) &&!is_int ($value) &&!is_float ($ Value) {
      $this->_error (self::invalid);
      return false;
    }
    $this->_setvalue ($value);
    $status = @preg_match ($this->_pattern, $value);
    if (false = = = $status) {
      $this->_error (self::errorous);
      return false;
    }
    if (! $status) {
      $this->_error (self::not_match);
      return false;
    }
    return true;
}

Perform validation work.

Custom Validator Authoring

Inherits the Zend_validate_interface interface to implement a user-defined validator.

A code case that functions to determine whether a specified number is a multiple of 3.

Interface code:

 }

To implement two of these methods, one is IsValid () and one is Getmessages ()

Implementation code:

<?php
require_once "zend/validate/interface.php";
Class Myvalidator implements zend_validate_interface{
  protected $_messages = Array ();
  Public Function IsValid ($value) {
    $this->_messages = Array ();
    $requirement =! ($value%3);
    if (! $requirement) {
      $this->_messages[] = "' $value ' cannot be divisible by 3"
      ; return false;
    }
    return true;
  }
  Public Function Getmessages () {return
    $this->_messages;
  }
}
function C_n_3 ($n) {
  $validator = new Myvalidator ();
  if ($validator->isvalid ($n)) {
    echo Specifies the value: ";
    echo $n. ", is a multiple of 3!" <p> ";
  } else{
    echo "specified value:";
    echo $n. ", not a multiple of 3!" <p> ";
    echo "failed message is:<p>";
    foreach ($validator->getmessages () as $message) {
      echo $message <p>
}}} $num 1 = 5;
$num 2 = 6;
$num 3 = 8;
C_n_3 ($num 1);
C_n_3 ($num 2);
C_n_3 ($num 3);

Results:

The specified value: 5, not a multiple of 3!

The failed message is:

' 5 ' cannot be divisible by 3

The specified value: 6, is a multiple of 3!

The specified value: 8, not a multiple of 3!

The failed message is:

' 8 ' cannot be divisible by 3

Comments:

Here, the IsValid () method is used to set the property information, and the Getmessages () method is used to get the error message. An error message is an array that traverses the read by the foreach () method.
