Hi all, I am new to web app development, zend framework and php. I have come across some code on the net to validate postcodes but due to the fact that eregi has been deprecated i am struggling to edit this code so it can work for my purpose. Are there any gurus here that can show me how to edit this code?
<?php
class Zend_Validate_PostcodeUK extends Zend_Validate_Abstract{
const NOT_MATCH = 'postcodeNotMatch';
/**
* @var array
*/
protected $_messageTemplates = array(
self::NOT_MATCH => "'%value%' is not a valid UK post code"
);
/**
* Defined by Zend_Validate_Interface
*
* Returns true if and only if $value matches against the postcode patterns
*
* @param string $value
* @return boolean
*/
public function isValid($value)
{
//Set the value for error messages
$this->_setValue($value);
// Permitted letters depend upon their position in the postcode.
$alpha1 = "[abcdefghijklmnoprstuwyz]"; // Character 1
$alpha2 = "[abcdefghklmnopqrstuvwxy]"; // Character 2
$alpha3 = "[abcdefghjkstuw]"; // Character 3
$alpha4 = "[abehmnprvwxy]"; // Character 4
$alpha5 = "[abdefghjlnpqrstuwxyz]"; // Character 5
// Expression for postcodes: AN NAA, ANN NAA, AAN NAA, and AANN NAA
$pcexp[0] = '^('.$alpha1.'{1}'.$alpha2.'{0,1}[0-9]{1,2})([0-9]{1}'.$alpha5.'{2})$';
// Expression for postcodes: ANA NAA
$pcexp[1] = '^('.$alpha1.'{1}[0-9]{1}'.$alpha3.'{1})([0-9]{1}'.$alpha5.'{2})$';
// Expression for postcodes: AANA NAA
$pcexp[2] = '^('.$alpha1.'{1}'.$alpha2.'[0-9]{1}'.$alpha4.')([0-9]{1}'.$alpha5.'{2})$';
// Exception for the special postcode GIR 0AA
$pcexp[3] = '^(gir)(0aa)$';
// Exception for the special postcode SAN TA1
$pcexp[4] = '^(san)(ta1)$';
// Standard BFPO numbers
$pcexp[5] = '^(bfpo)([0-9]{1,4})$';
// c/o BFPO numbers
$pcexp[6] = '^(bfpo)(c\/o[0-9]{1,3})$';
// Load up the string to check, converting into lowercase and removing spaces
$postcode = strtolower($value);
$postcode = str_replace(' ', '', $postcode);
// Assume we are not going to find a valid postcode
$valid = false;
// Check the string against the six types of postcodes
foreach ($pcexp as $regexp) {
if (ereg($regexp,$postcode, $matches)) {
// Load new postcode back into the form element
$value = strtoupper($matches[1] . ' ' . $matches [2]);
// Take account of the special BFPO c/o format
$value = ereg_replace('C\/O', 'c/o ', $value);
// Remember that we have found that the code is valid and break from loop
$valid = true;
break;
}
}
// Return false and set error message
if(!$valid) {
$this->_error();
return false;
}
return true;
}
}
