Passing a value via href - php

I recently started working with PHP, and MySQL. And I have come with a little problem, I have tried a couple of things to solve it and they are not working. Well, basically I am trying to put a link on a page, but that page requires me to pass a value, here's an example below, e.g.

If I am on this page for example
PHP Syntax (Toggle Plain Text) 
  1.  http://www.mypage.com/view.php?prop_id=5
and I want to add a link, that would translate to
PHP Syntax (Toggle Plain Text) 
  1. <a href="submit_docs.php?prop_id=5 ">Click </a>
How do I accomplish this, how do I pass the php variable "prop_id" to a href link? Can someone shed me some light on this matter? Thanks a lot

Um, you do it exactly like you have indicated in your link. I'm not certain what your question is exactly. Are you unsure how to build the link string? Unsure how to retrieve the value in the target page? Please elaborate a bit.

Yes, I am not sure how to build the link string that would pass the prop_id=[current_id_value] variable. I typed the prop_id=5 as an example, technically it could be any number. I am guessing there is a way to get the variable from the MySQL database, but once I get it, how do it build the link. Thanks again

What do you mean by trabslate ?

If you want to you use prop_id from view.php url in link :

php Syntax (Toggle Plain Text) 
  1. $prop_id = '$_GET[prop_id]';
  2.  
  3. echo "<a href=\"submit_docs.php?prop_id=".$prop_id."\">Click </a>";

It works! Thanks a lot Mitko, and everyone who viewed this post By using the code:

php Syntax (Toggle Plain Text) 
  1.  echo "<a href=\"submit_docs.php?prop_id=".$prop_id."\">Click </a>";

I get the link with the prop_id variable. However I want to point something out, if I try to use for example
php Syntax (Toggle Plain Text) 
  1. $varid_id = '$_GET[prop_id]';
And used $varid_id instead of $prop_id I get an error, In other words, I did not have to declare $prop_id to use it in the link.
Again thanks a lot

He just included that as an example of retrieving prop_id from a GET page request. If prop_id had been passed in via a link, you would get it with that code. If you are generating the prop_id from another source, you wouldn't need to pull it from the $_GET[] array.
