Redirecting attachment pages in WordPress

by

Spammers are a crafty bunch, using a variety of techniques to spread their unwanted junk. One way they do this is by submitting comments to the special pages WordPress creates for each image that has been uploaded. Spammers find these pages and submit spam. But there are ways to thwart their misdeeds!

7 Ways to Redirect WordPress Attachment Pages

Lately we’ve been using the Redirect Attachment Pages plugin, if the client does not have it available through an SEO plugin.

Validating fields in Gravity Forms

by

Despite CAPTCHA, spammers have been submitting spam forms on a few of our client’s websites. The submissions usually have the same first and last name, and often contain a website address in the message. I was able to add a little code to the theme’s functions.php to prevent this type of thing.

add_filter( 'gform_validation_1', 'validate_contact_fields_1' );
function validate_contact_fields_1( $validation_result ) {
    $form = $validation_result['form'];
  
    // first and last name can't be the same
    if ( rgpost( 'input_1' ) == rgpost( 'input_2' ) ) {
  
        // set the form validation to false
        $validation_result['is_valid'] = false;
  
        //finding Field with ID of 1 and marking it as failed validation
        foreach( $form['fields'] as &$field ) {
  
            //NOTE: replace 1 with the field you would like to validate
            if ( $field->id == '1' ) {
                $field->failed_validation = true;
                $field->validation_message = 'First and Last Name can not be the same.';
                break;
            }
        }
  
    }
    // Message can't contain a URL
    $nourl_pattern = '(http|https)';
    if ( preg_match( $nourl_pattern, rgpost( 'input_4' ) ) ) {

		$validation_result['is_valid'] = false;
        foreach( $form['fields'] as &$field ) {
  
            if ( $field->id == '4' ) {
                $field->failed_validation = true;
                $field->validation_message = 'Message can not contain website addresses.';
                break;
            }
        }
    }
  
    //Assign modified $form object back to the validation result
    $validation_result['form'] = $form;
    return $validation_result;
  
}  // end function validate_contact_fields_1
