问题
I need to send an URL of my site in the body so the mail recipient can click on that to join my site.
However currently mail client renders the mail like this:
Link goes here http://www.example.com/foo.php?this=a
The URL is truncated on the & symbol, thus the whole process of joining failed. How can I pass the URL like http://www.example.com/foo.php?this=a&join=abc&user454 in mailto body?
My current HTML is the following:
<a href="mailto:test@test.test?body=Link goes here http://www.example.com/foo.php?this=a&really=long&url=with&lots=and&lots=and&lots=of&prameters=on_it
">Link text goes here</a>

You need to encode the URL. This URL Decoder/Encoder tool will do the trick. The following seems to work:
<a href="mailto:test@test.test?body=Link goes here http%3A%2F%2Fwww.example.com%2Ffoo.php%3Fthis%3Da%26join%3Dabc%26user454
">Link text goes here</a>

I would URL encode the link you are using, so it would be:
<a href="mailto:test@test.test?body=Link%20goes%20here%20http%3A%2F%2Fwww.example.com%2Ffoo.php%3Fthis%3Da%26join%3Dabc%26user454">Link text goes here</a>

You can type javascript:alert(escape("YOUR URL")); in the address box of a browser and get the URL made safe for a mailto link. For example, type the following inside the address box of a browser and press Enter.
javascript:alert(escape("http://www.example.com/foo.php?this=a"));
You will get a message box that will display.
http%3A//www.example.com/foo.php%3Fthis%3Da
Opera and Mozilla-based browsers allow you to copy the displayed content from the alert box.
You could improve it by typing
javascript:alert("mailto:MyEmailAddress@Example.com?subject=My Subject&body="+escape("http://www.example.com/foo.php?this=a"));
so that you get the subject and body included in the link. Other improvements could be using a From name and line breaks using %0a.
javascript:alert("mailto:Just Me <CMyEmailAddress@Example.com>?subject=My Subject&body=This is the link:%250a"+escape("http://www.example.com/foo.php?this=a"));

as I see you are using php then you can use "urlencode()" function
<a href="mailto:test@test.test?body=Link goes here <?php echo urlencode('http://www.example.com/foo.php?this=a&really=long&url=with&lots=and&lots=and&lots=of&prameters=on_it
');?>">Link text goes here</a>
