Hello Dan,
Good point. I like your idea, but it adds a little more processing since I'd
need to
be handling these pages w/sessions, to thwart potential misuse/abuse.
I like the attachment as a .pdf idea as well.
I'll have to see if its something the client wants before I get too far with
it.
The code snippet you send me works for some, but doesn't work for others.
Some characters
are still breaking it. Or maybe, mailto has a limit for body size.
Not sure.
Thank you!
- Ben

Hello All,
I've created a "Mail this section" option for a FAQ/Information Center
type page I'm working on.
It enables visitors to email themselves the contents of a particular
section. But I'm running into trouble
when foreign/non a-zA-Z0-9 characters are present in the code (which is
being pulled from the database).
Heres' a code snippet:
$body .= "<a href=\"mailto:?Subject=Information Center&body="
. html_entity_decode(strip_tags(
str_replace(array("&", '"', "\\"), "",
$dbObject->result['body']))) . "\""
. " class=\"email\">Email this section</a>";
Let me reformat that, heh:
$body = "<a href=\"mailto:?Subject=Information Center&body=".
$dbObject->result['body'] . "\">Email me</a>";
So, what can I use on $dbObject->result['body'] to clean/strip away the
text? You can see I was messing
with a few different options..I know & will break it, as well as " ...
but lets just clear out everything (HTML, and all other characters EXCEPT
aA-zZ 0-9 and maybe .,-
Any help, greatly appreaciated!
Personally, I think you're probably approaching this the wrong way.
Not only are you going to be generating huge links (which will cause all
kinds of grief), but your email will be horribly formatted and the user
still has to email it to themselves manually from their own mail
client...very confusing.
Why not have the link trigger a server-side process to send the mail?
You may need an input for the user to enter their email address, but
then you can format the mail in any way you like, using whatever
character set is appropriate for the content.
For bonus marks, attach it as a nicely formatted pdf!
As an aside, when creating any kind of url, there are 2 forms of
formatting you need to consider.
1. urlencode any query strings
2. html encode the entire url to make it html-safe
for example:
echo '<a href="'. htmlspecialchars('test.php?arg1='. urlencode('val1')
.'&arg2='. urlencode('value 2 with some odd characters & +'))
.'">link</a>';
I define functions h() and u() as shortcuts for htmlspecialchars and
urlencode respectively, as I use them everywhere.
If you did want to make your current approach work, you would want to do
something like:
$body = '<a href="'. h('mailto:?Subject='. u('Information Center')
.'&body='. u($dbObject->result['body'])) .'">Email me</a>';
HTH,
Dan
