Re: How to format text in a mailto:

I use this to validate the email address entered into a form. Might be
useful:

function ValidateEmailAddress($EmailAddress){
$EmailAddress = strtolower(trim($EmailAddress));
if (!eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z
{2,4})$", $EmailAddress)){
return FALSE;
} else {
return $EmailAddress;
}
}

Could someone please help with a mailto action
I am trying something like this, I want the text in $the_message to be
formatted. The results I get is unformatted. line 1 line 2 line 3 line
4 ... line etc.

<?
<a href='mailto:email@xxxxxxx&subject=$subject&body=$the_message'>mail
me</a> ?>

<? $the_message=
" line 1\n"
." line 2\n"
." line 3\n"
." line 4\n"
." line 5\n"
." line 6\n"
." line 7\n"
." line etc.\n";
?>

Ouch! Using the client's default email program in this way is very
unreliable. Not everyone has a (default) mail program, and not all mail
programs understand 'body=.' :(

But if you still want to go down that route replace \n at the end of
each line with %0d.


Thanks for the advice Martin, sounds like I would be opening up a can of
worms if I do it my way. I"ll use a form instead, the client can put their
email address in and sent it.

Anytime you use forms to send email, you want to be careful and validate
the form data first. As an example, you want to may sure any form field
information that could potentially be used in a mail header (e.g.
$_POST['email'] = 'email@xxxxxxx') is checked for extra addresses (such as
"email@xxxxxxx,email2@xxxxxxx,email3@xxxxxxx").

Also want to check for newline characters where people can mess with your
web
form if they had too much free time. As as example
"email@xxxxxxx,email2@xxxxxxx,email3@xxxxxxx\nBcc:more email
addresses.......". The "\nBcc:" adds another header where mail is blind
copied to whatever recipients re listed. Not to make you paranoid, but you
do want to be careful with mail forms open to the public because some
people like to start trouble.
