Hi,<\/p>\n

I have an issue on registering a user at an event.<\/p>\n

I’m using Event Tickets Plus plugin just to have a QR Code in our ticket email. I don’t know if you need this information to help me but I’m not using this plugin for an e-commerce solution. Here are the restrictions we have for event registration via ticket :<\/p>\n

    \n1 – There is always only one existing ticket for an event.
    \n2 – In order to register to the event, the user need to be connected
    \n3 – The user can’t register multiple times at the same event
    \n4 – The user can only register himself for the event (The User ID have to match the User email)\n<\/ol>\n

    I was able to match all those restrictions by override the plugin templates but I was able to catch a way to register a user multiple times at the same event :<\/p>\n

    Let’s say I’m a connected user and I’m accessing a new event page where I’m not registered.
    \nSo on this page, I can register to the event only by clicking this button. Then the page will refresh and it’ll display another button to access to the ‘orders.php’ template page.<\/p>\n

    But imagine that before I register to the event, I open the same page in another tab, I have now 2 pages with the same “Register to the event” button, and will be able to register myself twice to the same event.<\/strong><\/p>\n

    I would like to know if I can hook just before the user try to register in order to check if his already registered.
    \nIf I can’t use hook because the plugin can completely change his architecture, how can I prevent the user to register multiple times to the same event?<\/p>\n

    Thank you!<\/p>\n","protected":false},"template":"","class_list":["post-1319679","topic","type-topic","status-closed","hentry"],"yoast_head":"\nHow can I prevent the user to register multiple times to the same ticket -<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/theeventscalendar.com\/support\/forums\/topic\/how-can-i-prevent-the-user-to-register-multiple-times-to-the-same-ticket\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"How can I prevent the user to register multiple times to the same ticket -\" \/>\n<meta property=\"og:description\" content=\"Hi, I have an issue on registering a user at an event.
