Sending verification mail before registering user - PHP

Question

I am currently working on the PHP project in which I have to send the verification mail to the user who register in the site. (Email id is the username). I am having the following doubt.

• Whether I have to send them the verification email before storing the user in database or after storing the user in database.
• If I send the verification mail to the user after storing user in database what I have to do if the email is not sent from my server. Because user cannot able to re-register with the same email id.

Please help me in this problem. Thanks in advance

Answer 1

• you have to send mail after registration save details in db with key(that will send with link) and status like 0 in database . if they click on that link then delete activation key from database and also change status into 1 and on login you also need to check user have status 1 if not then you can show alert like Mail Confirmation Pending .

• after send mail you can check mail sent or not .check this question

Answer 2

I suggest you store the user in database and then send the verification email. In the database keep a field to mark whether user verified the email or not.

Give user an option to resend email verification incase they didn't receive.

Answer 3

As far as from my experience

1. Enter details in DB and then send the verification mail, else your in a situation that you cant verify the user back again.

2. In-case email sending fails from your side, provide a option for the user to request for resending of the verification mail.

3. Maintain a status in the DB whether a user is verified or not, and based on that you can resend the verification mail.
