multiple email addresses

jroscoe

I have a form field on my page where people can send a link to a friend, etc. I want to be able to allow them to enter more thatn 1 email address seerated by a "," and also validate the email addres before sent.

In my form, I have the text field named as "email_addr[]"

on my validate routine, I have the following:
foreach ($email_addr as $em) {
if (!strlen(trim($em))) {
$err_email="Please enter an email address";
$err_cnt++;
} else {
if (!validate_email($em)) {
$err_email = "Please enter a valid email address";
$err_cnt++;
}
}
}

and in my mail script, I have the following:
$arr_num = count($email_addr);
for ($i=0; $i<=$arr_num; $i++) {
$recipient=$email_addr[$i];

$subject=$subject;
$body="Directions have been sent to you. "
.$comments . " "
."To view your directions, click on this link or cut and paste this link into your browser's location bar: "
."<a href=" . $url . ">" . $url_abbr . "</a> "
.$footer;

$headers = "MIME-Version: 1.0\n";
$headers .= "Content-type: text/html; charset=iso-8859-1\n";
$headers .= "From:" . $from . "\n";
$headers .= "X-Mailer: PHP/" . phpversion();

mail($recipient, $subject, $body, $headers);
}

My problem is that if you only put 1 email address in, it works fine and I get my email. If you put in more thatn 1, seperated by the ",", it fails the validation.

Any suggestions?
Thanks!!

I tried the following in my validation function, but still get an error, "Please enter a valid email address:

$emails = explode(",", $email_addr);
foreach ($emails as $em) {
if (!strlen(trim($em))) {
$err_email="Please enter an email address";
$err_cnt++;
} else {
if (!validate_email($em)) {
$err_email = "Please enter a valid email address";
$err_cnt++;
}
}
}

Can anyone please help here?????

Perhaps trim() the email address? You're doing so, but remember that trim() doesn't alter its argument.

foreach($emails as $em)
{ $em=trim($em);
if(...)
...
etc.
}

Still get the error "Please enter a valid email address." when using the below function:

function validate_form() {
global $url, $email_addr, $from, $subject, $comments, $err_email, $err_subject, $err_from, $err_cnt;

$err_cnt = 0;

$emails = explode(",", $email_addr);
foreach ($emails as $em) {
$em=trim($em);
if (!strlen(trim($em))) {
$err_email="Please enter an email address";
$err_cnt++;
} else {
if (!validate_email($em)) {
$err_email = "Please enter a valid email address";
$err_cnt++;
}
}
}

In my form, the name of the textbox is "email_addr[]". Is that still ok? I'm kind of new to php. Thanks.

Mm.. probably not. I think "email_addr" is sufficient.

What you're wanting to send is a comma-separated string - which you'll later turn into an array with explode().

Calling the field "email_addr[]" makes $email_addr an array containing one element which is a comma-separated string. If you try and treat that as a string, it will be treated as if it said "Array" - which is not a valid email address.

Cool, thanks guys, it works now. But, I have one more idea. In the to field in the email, it lists both email addresses. How can I make it so that it only shows the email address of the person it is going to? Here is what my mail script looks like:

/ e-mail.... /
$arr_num = count($email_addr);
for ($i=0; $i<=$arr_num; $i++) {
$recipient=$email_addr;

$subject=$subject;
$body="Directions have been sent to you. "
.$comments . " "
."To view your driving directions, click on this link or cut and paste this link into your browser's location bar: "
."<a href=" . $url . ">" . $url_abbr . "</a> "
.$footer;

$headers = "MIME-Version: 1.0\n";
$headers .= "Content-type: text/html; charset=iso-8859-1\n";
$headers .= "From:" . $from . "\n";
$headers .= "X-Mailer: PHP/" . phpversion();

mail($recipient, $subject, $body, $headers);
}
