Redirect page on date and time from Everwebinar URL-CodePudding

I would like to be able to redirect a custom Everwebinar confirmation page (on my domain) visitor to a specific URL at a given date and time that is contained in a confirmation page URL.

The confirmation page URL looks like this:

https://website.com/pagename?preview_theme_id=2151207349?wj_lead_email=email@outlook.com&wj_lead_first_name=FirstName&wj_lead_last_name=LastName&wj_lead_phone_country_code=&wj_lead_phone_number=&wj_lead_unique_link_live_room=https://event.webinarjam.com/go/live/1/k6znqu2twiyznhp42&wj_event_ts=1658918700&wj_event_tz=Europe/London&wj_next_event_date=Wednesday, 24 August 2022&wj_next_event_time=2:00 PM&wj_next_event_timezone=London GMT +1

A simple javascript redirect would be suitable as long as the redirect date, time and URL are all pulled from the confirmation page URL above as each visitor will have a unique URL.

Thank you in advance for your help.

Firstly, it should be noted that the confirmation page URL you gave as an example contains two question marks, which is not valid. This may be a typo, but there should only be one question mark before the URL search parameters, with all search parameters being separated by an ampersand (&).

That being said, there area several methods available to get the values of the URL search parameters and then redirect based on the date/time provided in the URL. The main thing used here is URLSearchParams(), which allows you to get an object that contains all of the search parameters available. From there, the wj_event_ts is a timestamp that can be used to compare dates/times.

For this example I will use the URL you provided, but if this JavaScript is being run on that confirmation page, I have commented out how to grab the current URL instead.

// If run on the actual confirmation page, use:
// let currentURL = window.location.href;

let currentURL = new URL("https://website.com/pagename?preview_theme_id=2151207349&[email protected]&wj_lead_first_name=FirstName&wj_lead_last_name=LastName&wj_lead_phone_country_code=&wj_lead_phone_number=&wj_lead_unique_link_live_room=https://event.webinarjam.com/go/live/1/k6znqu2twiyznhp42&wj_event_ts=1658918700&wj_event_tz=Europe/London&wj_next_event_date=Wednesday, 24 August 2022&wj_next_event_time=2:00 PM&wj_next_event_timezone=London GMT +1"),
searchParams = new URLSearchParams(currentURL.search),
nextEventDate = new Date(`${searchParams.get("wj_next_event_date")} ${searchParams.get("wj_next_event_time")} ${searchParams.get("wj_next_event_timezone").substr(searchParams.get("wj_next_event_timezone").indexOf("GMT"))}`);

if(Date.now() >= searchParams.get("wj_event_ts")*1000) {
  // It is currently past the date in the URL
  console.log("Redirecting... Current Event");
  //window.location.href = searchParams.get("wj_lead_unique_link_live_room");
}

// If you want to use the next_event_date value instead, use this section
if(Date.now() >= nextEventDate.getTime()) {
  console.log("Redirecting... Next Event");
  //window.location.href = searchParams.get("wj_lead_unique_link_live_room");
}

EDIT It looks like you have multiple dates in the URL and it was not specified which date/time you would like to use. I have added another commented out section to use the next_event_date value instead of the event_date timestamp.

I used another method of getting the URL parameters and that worked.

const queryString = window.location.search;
console.log(queryString);
const urlParams = new URLSearchParams(queryString);

if (urlParams.has('wj_event_ts')) {
  if(Date.now() >= urlParams.get('wj_event_ts')*1000) {
    // It is currently past the date in the URL
    console.log('Redirecting... Current Event');
    window.location.href = urlParams.get('wj_lead_unique_link_live_room');
  }
}
