Coupon codes

Hello @dennisemaar

I’ve tested Coupon add-on from y end and could not reproduce an issue. Please share here URL link to your site; let us know what PHP version your site is running.

Please check if a coupon can be added when all other plugins deactivated, except MarketPress. If all is well, start activating one plugin at the time, while testing if a coupon can be added, till you find a plugin that can cause a conflict.

If i’m using the assessment tab in coursepress, and i’m grading with feedback, i can’t submit the grading with feedback. I can only grade without feedback.

I could not also reproduce the issue with CoursePress plugin. Please follow the above steps and check if the grade can be submitted with all other plugins deactivated.

Let us know how it went!

Cheers,
Nastia

Hey @dennisemaar,

Hope you’re well.

I tested MarketPress and CoursePress too and couldn’t replicate the problem. For this reason, maybe our plugins are just conflicting with your theme. Can you try with default WordPress theme?

Also, when I go to http://dennisemaar.nl/store/advies-over-te-o…ikkelen-gebieden/ this page I am getting a 404 error. Can you check is your website accessible without logging in?

About CoursePress if the problem continues and not related with MarketPress integration can you open a new thread on its support forum? If it’s related we can stick here.

Hey @dennisemaar,

Hope you’re well.

Thank you for working URL. I checked the coupon section and yes you’re right it stuck when you enter the correct coupon. And I can see there is a 500 error for ajax request from chrome developer console.

To understand what cause this problem we need to check WordPress debug logging and PHP debug logging. First of all can you edit wp-config.php file and put these codes;

/* Debug Settings */
define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);
/* End of Debug Settings */

Then try entering correct coupon one more time(try to replicate issue again). Then check wp-content folder. Is there any debug.log file? If yes please share the content with us. If no then check the server PHP logs, is there any related logs?

Hey @dennisemaar,

Hope you’re well.

Thank you for the results. Can you replace is_valid function (approximately 451nd line) in {wordpress_folder}/wp-content/plugins/marketpress/includes/addons/mp-coupons/class-mp-coupon.php file via FTP. Final function should be look like;

public function is_valid( $action = '' ) {
	$now      = time();
	$is_valid = true;

	//Moved to variable as it will be used in many instances
	$cart_products = $this->get_products( true ) ;

	$coupon_start 			= get_post_meta( $this->ID, 'start_date', true );
	$coupon_end 			= get_post_meta( $this->ID, 'end_date', true );

	if ( ! $this->exists() ) {
		$is_valid = false;
	} elseif ( $this->remaining_uses( false, true ) == 0 ) {
		$is_valid = false;
	} elseif ( $now < strtotime( $coupon_start ) ) {
		$is_valid = false;
	} elseif ( $this->get_meta( 'has_end_date' ) && ( $now > strtotime( $coupon_end ) ) ) {
		$is_valid = false;
	} elseif ( array() == $cart_products) {
		$is_valid = false;
	}elseif( ! $this->valid_for_number_of_products( $cart_products ) ){
		$is_valid = false;
	}elseif( ! $this->valid_for_login() ){
		$is_valid = false;
	}else {
		if( $action != 'remove_item' ) {
			if ( $this->get_meta( 'applies_to' ) == 'user' ) {
				$user = $this->get_meta( 'user' );

				if ( !in_array( get_current_user_id(), $user ) ) {
					$is_valid = false;
				}
			}

			if( ! $this->is_valid_for_combination() ) {
				$is_valid = false;
			}
		}
	}
        /**
	 * Filter is coupon is valid
	 *
	 * @since 3.0
	 *
	 * param bool Is valid?
	 * param MP_Coupon The current coupon object.
	 */

	return apply_filters( 'mp_coupon/is_valid', $is_valid, $this );
}

I hope it helps!
