Mass email script.

[Sayian]

I am developing a script to accept up to 20 email addresses and email them an invitation to join my website. I have searched this forum, and found a couple usefull things but not exactly what im looking for.

On my HTML page, i will have 20 textboxs that will be used to collect the email addresses of friends they want to invite.

On form submission, in my php script would i have to check for every textbox?

if(isset() and strlen() ) {

// send email

}

Or is their a way i could check all the textbox's and process the ones that had a valid email address? I was thinking i could use a while loop .. but how would i input all the names of the textboxes .. Im a little confused.

Someone lead me in the right path .. thanks.

something like this, but using a mail function instead i guess; adapt it to your own needs

<?php
for($i=1;$i<=20;$i++) {
     echo $_POST['textbox{$i}'];
}
?>

Sorry, I haven't tested this out, but try something like it anyway.

How would i get the textbox name for each text box?

if i had 20 textbox's , they all have to have a unique name right?

IE: textbox1, textbox2, ect ect to 20

If these are coming from an HTML page, then how would i do this? I dont understand the concept of how to get the email from each textbox ... I can do the mail() part .. but im confused on how to get the email from different textbox names and make this work with 1 for loop

use:

name="textbox[]"
name="textbox[]"
name="textbox[]"
name="textbox[]"

and

foreach ($textbox as $text)
