[Resolved] Lost Passwords

[cbrknight]

Anyone tell me how I can generate a new password when someone sends me their email address?

I also need to be able to email them their new password using php but sending through SMTP...

Thanks

what are your password contraints? (# of chars, numbers, letters, etc...)

[man]mail[/man]

Standard unix password format is fine

8 chars
caps and lowercase
alpha and numeric

Thanks

I have looked at that link before and quite frankly... it is very cryptic. I can use the sendmail function in php easily enough. I wish my boss had not chosen an smtp server but wish in one hand....right

the problem is that when those people start talking about the smtp part of send mail they tend to be a bit vague...

do you know of somewhere that has some specific examples of sending email in php? or maybe the pear functions they talk about?

What else would you use to send email exactly?

mail($to,$subject,$message);

[cbrknight]

mail($to,$subject,$message);

OK you were right. when I tried this a few days ago it wouldnt work. I just tried it again and it did. So now all I need is a way to create the new password and send it via this method.

Thanks.

If you're on a nix box which doesn't have an MTA with Sendmail wrappers (which is pretty unlikely but sounds like what you're talking about) you're going to have to manually open up a socket to your smtp server and send the mail like that. This may sound like a long winded way of doing things but if you're sending out a large number of emails it's a lot* quicker. I've knocked up a very skeletal class to handle this kind of thing. There's no commenting, no error handling and no debuging output but I can't go spoiling you can I.

If you need any help with it just ask.

WHAT?!
I spent an hour and a half putting that together and tidying it up from little bits and bobs around my maintenance area, only to find out you don't fscking need it! Are you taking the p!ss? :mad:

ssh [email][e-mail][/email]
rm -f $(which sendmail)

That'll fix all your problems
:evilgrin:

...

...

😉 hehe

[cbrknight]

Sorry bubblenut

I was reading onion2k's post and he seemed so sure that the mail function should be working that I had to do some testing. When it worked I came to reply but you had already posted.

I am very sorry... I am sure I will put your code to use at some point with this nightmare of a website.

:evilgrin:

I do still need to know how to create a new password and send it to the email address they input.

😃

There are several umpteen threads on this subject already in the forums (try searching for generate password or random password, for example). There are also articles on the subject on this site.

Thanks for all the help. Got both problems solved now.
