重力形式：日期验证失败

Question

我在 WordPress 上的 functions.php 文件中设置了此过滤器，用于验证日期，因此取件日期时间早于 return 日期和时间。当日期和时间输入正确时，它应该通过验证，但它一直失败，我无法理解这一点。它只是突然停止工作。我只能指出这一点以将服务器上的 date/time 设置为格林威治时间。

add_filter( 'gform_validation', 'custom_validation' );
function custom_validation( $validation_result ) {

    $form = $validation_result['form'];
    $pickupDate = null;
    $returnDate = null;

    foreach( $form['fields'] as & $field ) {
        if ( $field->label == 'Pickup Date' ) {
            $pickupDate = rgpost('input_' . $field->id);
            //var_dump("Pickup Date:" . $pickupDate);
        }

        if ( $field->label == 'Pickup Time' ) {
            $pickupDate .= ' ' . rgpost('input_' . $field->id);
            //var_dump("Pickup Time:" . $pickupDate);
        }

        if ( $field->label == 'Return Date' ) {
            $returnDate = rgpost('input_' . $field->id);
            //var_dump("Return Date:" . $returnDate);
        }

        if ( $field->label == 'Return Time' ) {
            $returnDate .= ' ' . rgpost('input_' . $field->id);
            //var_dump("Return Time:" . $returnDate);

            if (strtotime($returnDate) <= strtotime($pickupDate)) {

                //var_dump($returnDate);
                //var_dump($pickupDate);

                $validation_result['is_valid'] = false;
                $field->failed_validation = true;
                $field->validation_message = 'Please ensure your selected Pickup Date and time is earlier than your Return Date and Time';
                break;
            }
        }
    }

    //Assign modified $form object back to the validation result
    $validation_result['form'] = $form;

    return $validation_result; 
}

add_filter( 'gform_pre_send_email', function ( $email, $message_format ) {
    if ( $message_format != 'html' ) {
        return $email;
    }

    if (strpos($email['message'], 'Pickup Date') !== false) {
        $email['message'] = explode('Pickup Date', $email['message']);
        $email['message'][1] = str_replace('/', ', ', $email['message'][1]);
        $email['message'][1] = str_replace('<, ', '</', $email['message'][1]);
        $email['message'] = implode('Pickup Date', $email['message']);
    }
 
    $email['message'] = '<html>' . $email['message'] . '</html>';
 
    return $email;
}, 10, 2 );

日期以这种格式输出。

string(22) "Pickup Date:25/06/2020" 
string(28) "Pickup Time:25/06/2020 08:00" 
string(22) "Return Date:26/06/2020" 
string(28) "Return Time:26/06/2020 08:00"

谁能找出问题所在？

您只需从验证条件中删除 =。

add_filter( 'gform_validation', 'custom_validation' );
function custom_validation( $validation_result ) {

$form = $validation_result['form'];
$pickupDate = null;
$returnDate = null;

foreach( $form['fields'] as & $field ) {
    if ( $field->label == 'Pickup Date' ) {
        $pickupDate = rgpost('input_' . $field->id);
        //var_dump("Pickup Date:" . $pickupDate);
    }

    if ( $field->label == 'Pickup Time' ) {
        $pickupDate .= ' ' . rgpost('input_' . $field->id);
        //var_dump("Pickup Time:" . $pickupDate);
    }

    if ( $field->label == 'Return Date' ) {
        $returnDate = rgpost('input_' . $field->id);
        //var_dump("Return Date:" . $returnDate);
    }

    if ( $field->label == 'Return Time' ) {
        $returnDate .= ' ' . rgpost('input_' . $field->id);
        //var_dump("Return Time:" . $returnDate);

        if (strtotime($returnDate) < strtotime($pickupDate)) {

            //var_dump($returnDate);
            //var_dump($pickupDate);

            $validation_result['is_valid'] = false;
            $field->failed_validation = true;
            $field->validation_message = 'Please ensure your selected Pickup Date and time is earlier than your Return Date and Time';
            break;
        }
    }
}
//Assign modified $form object back to the validation result
$validation_result['form'] = $form;

return $validation_result; 
}
