mysql - How to auto generate a random unique permanent secure ID based on current url, store it automatically inside database and display it in php page? -


I need help in creating a random unique permanent secure id based on the current URL to the generated URL Php page?

I have a multisite and make a new subdomain every time, I want to display a unique safe ID based on the current new subdomain on the page and likes to display it in my page: < / P>

ID Page Safe Numbers : 6465465DSGDGDGDG4564EEEZ7778

PHP has a hashing function that you can use. I will also add a random salt to it, actually there can be anything like a string of text or numbers 

  $ url = $ _SERVER ['HTTP_HOST']; $ Salt = "i.am.a.rand0m.str1ng.ff.ChAAcT3r $"; Echo hash ('sha1', $ url. $ Salt);   
 There are other hashes you can use:  
 PHP also has a task, but it requires 5.5.0 or more.  
  Edit  The URL for $ _SERVER ['HTTP_HOST'] has been ejected, though there are probably a better way of getting the current URL

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon. So if you are already offering discounts to the coupon, then the customer who is currently in the present will also give up. It also means that if you are using a recently-added multiple subscription capacity, then all of the user's subscription will be ready for the month. Coupons can be set to "Once", only once (as the only name) can be used by any customer, so if this credit can earn more than once, You will have to maintain a 100% discount coupon continuousl...
