php to append emails to text file

[ice9]

I'm looking for a simple modification to register.php that will append the email addresses of newly registered users to a text file for addition to my mailing list (lyris). I looked through the hack archives, and found some other more robust mailing list features, but I'm looking for something a lot simpler. I'm coming from a perl background, and am relatively new to php.

I just need a plain checkbox on my registration form "check here to receive our newsletters, etc.", that will append the email to a text file. Then, I'll just cron something nightly to add the email addresses to my lyris list. I don't need to check it against a list to see if they are already subscribed.

in register somewhere (I'd suggest just below the insert database query around line 459 in register.php

PHP Code:

$fp = fopen("emails.txt", "a");
    fwrite($fp, "$email\r\n");
fclose($fp); 


That directory will have to be chmod'ed for writing (777) however. You may wish to stick the text file somewhere below root level

PHP can access anywhere in the file system if I'm not mistaken. So put your mailing list ABOVE the web root folder in a writable folder. It's safe from hackers and you don't have to have a public writable folder.

I think that's what I meant The path would be something like:
/home/username/emails.txt

Thanks -- that was easy . Is there a simple way to only append the email to the text file if a checkbox was checked? This way, I can keep my list opt-in only.

Try this.

in the register templates add...
<tr>
<td bgcolor="{firstaltcolor}"><normalfont><b>Join our mailing list?</b></normalfont><br>
<smallfont>Selecting yes will add you to our mailing list.</smallfont></td>
<td bgcolor="{firstaltcolor}"><normalfont>
<input type="radio" name="wantsmail" value="yes"> yes
<input type="radio" name="wantsmail" value="no" checked> no
</normalfont></td>
</tr>

in register.php at around line 350 add

$maillist=iif($wantsmail=="yes",1,0);

then wrap the append code in an if()...

if($maillist) {
$fp = fopen("emails.txt", "a");
fwrite($fp, "$email\r\n");
fclose($fp);
}

This is not tested.
