Hello
I use a mail()-feedback creating a html-mail on one page. The $textbody contains the html-code with all variables of the formular, trivial so far. But I want to get the user's screen-resolution in the feedback-mail as well. As I understand, the necessary javascript must already have been executed on the client, when the server runs the php-script with the mail-function. So do I need to send the js-variables containing the resolution-values from each page, which may direct to the mail-script? Could I get the resolution on index.htm an store it for later use, perhaps by passing it in the URL? I never did that before so I don't know how to pass it with js and how to read the values with php. Okokok - you might say RTFM but this question seems to be too simple for mentioning it in a manual.
The script I'm working on is on

Thank You for any help

Re: email-feedback including screen resolution
My JavaScript is lousy, so I can't give you many specifics, but here's how I'd do it: On the page with the mail form, have a hidden form field, e.g.
Then, on the page, put JavaScript that detects the resultion when the page loads and sets the value of the hidden form field to the detected resolution. Then, when the form is submitted, you can just add the contents of the field (e.g. $_POST['resolution']) to your e-mail message.
I hope that's helpful. You'll have to come up with the actual JavaScript on your own, unless someone else wants to provide it.
Code: Select all
<input type="hidden" name="resolution" value="">Then, on the page, put JavaScript that detects the resultion when the page loads and sets the value of the hidden form field to the detected resolution.

I'm stuck
It doesn't work. What I did in the <head> of this mail.php:
<script language="JavaScript">
var hoehe, breite, farbe, aufloesung;
high = screen.height;
wide = screen.width;
col = screen.colorDepth;
var resolution = wide + "x" + high + "Color:" + col;
</script>
In the form (action="mail.php"):
<input type="hidden" name="resolution" value="">
$res = $_POST['resolution'];
and in the html-body of the email I called $res. Nothing.Empty.
I don't know whether it's a simple script mistake or a basic misunderstanding of how php and javascript are executed. I thought, the javascript is run, when the page is loaded for the first time. The POST of the formular calls the same php-code again with the variables' values set in the form. Now where is the value of the hidden 'resolution' field...gone...Nirvana?

At some point you actually have to assign the value to the hidden form field. I'm not sure exactly, but once you have the visitor's resolution in the JavaScript variable "resolution", you should be able to put it into the form field like so:
Now don't just copy my code verbatim, because, as I said, my JavaScript is crap. I'm sure someone else around here can tell you if the above will work.
Code: Select all
<input type="hidden" name="resolution" value="<script language="JavaScript">document.write(resolution)</script>">Now don't just copy my code verbatim, because, as I said, my JavaScript is crap. I'm sure someone else around here can tell you if the above will work.
