以增加 ABN码自定义验证为例；
在 wordpress 主题根目录下的 functions.php 中添加如下代码；

//验证ABNadd_action('um_submit_form_errors_hook_','um_custom_validate_abn', 999, 1); function um_custom_validate_abn( $args ) { global $ultimatemember; if ( isset( $args['abn'] ) && !isValidAbnOrAcn($args['abn']) ) { $ultimatemember->form->add_error( 'abn', 'Abn code format error' ); } /*$args 为data-key值*/ } /** * Return true if $number is a valid ABN * @param string $number * @return bool True if $number is a valid ABN */ function isValidAbnOrAcn($number) { $number = preg_replace('/[^0-9]/', '', $number); if(strlen($number) == 9) { return isValidAcn($number); } if(strlen($number) == 11) { return isValidAbn($number); } return false; } /** * Validate an Australian Business Number (ABN) * @param string $abn * @link http://www.ato.gov.au/businesses/content.asp?doc=/content/13187.htm * @return bool True if $abn is a valid ABN, false otherwise */ function isValidAbn($abn) { $weights = array(10, 1, 3, 5, 7, 9, 11, 13, 15, 17, 19); // Strip non-numbers from the acn $abn = preg_replace('/[^0-9]/', '', $abn); // Check abn is 11 chars long if(strlen($abn) != 11) { return false; } // Subtract one from first digit $abn[0] = ((int)$abn[0] - 1); // Sum the products $sum = 0; foreach(str_split($abn) as $key => $digit) { $sum += ($digit * $weights[$key]); } if(($sum % 89) != 0) { return false; } return true; } /** * Validate an Australian Company Number (ACN) * @param string $acn * @link http://www.asic.gov.au/asic/asic.nsf/byheadline/Australian+Company+Number+(ACN)+Check+Digit * @return bool True if $acn is a valid ACN, false otherwise */ function isValidAcn($acn){ $weights = array(8, 7, 6, 5, 4, 3, 2, 1, 0); // Strip non-numbers from the acn $acn = preg_replace('/[^0-9]/', '', $acn); // Check acn is 9 chars long if(strlen($acn) != 9) { return false; } // Sum the products $sum = 0; foreach(str_split($acn) as $key => $digit) { $sum += $digit * $weights[$key]; } // Get the remainder $remainder = $sum % 10; // Get remainder compliment $complement = (string)(10 - $remainder); // If complement is 10, set to 0 if($complement === "10") { $complement = "0"; } return ($acn[8] === $complement); }
