Pass a subject argument to personal contact form?

Since I am a newbie to Drupal, those who are experts please forgive my naive work. I was on the right track, it seems. The way Drupal passes variables from one 'page' or 'view' to another is through arguments that are delimited by the '/' symbol and parsed into an array called 'arg' for use later. For the page I was working with did this, at least.

So, let us say that you have a page that you want to pass an argument to from another page's hyperlink. It works like so...

On the referring page, your anchor tag would include something like :

<a href=http://www.mysite.com/drupal/q=node/myVariableToPass1/>click me</a>

Then on the page where your want to do something with the variable, you'd call it up from its position in the array like so:

<?php echo arg(0); ?> // Will echo node <?php echo arg(1); ?> // Will echo the value of myVariableToPass1 as a literal string

Now, I don't know exactly how drupal will handle complex strings with non-alphanumeric characters, but the urlencode() function of php should be able to encode string text in such a way as to return the string in the next page correctly wht urldecode().

Hopefully, someone will find this enlightening, but since I have very little advanced Drupal development knowledge at this point, I could be doing this incorrectly. However, I have used this method on my site and it seems to be working properly so far.

I have been working on a similar issue myself. It appears from my research that this is probably done by using an arg() function for Views. I have yet to work out the particulars on this, but I think that I'm on to something here with parsing the arguments which follow the node portion of the url.
