How do I see if anything ... Aww just look, I don't know how to phrase this

[woodsonoversoul]

Currently when my script starts it checks to see if one "area of information" (what is a more acurate word?) has been posted :

 

// if id provided, then delete that record
if (isset($_GET['id'])) {
    // create query to delete record
     $query = "DELETE FROM purchase WHERE sale_id = '{$_GET['id']}'";

 

How can I check to see if any area of information has been posted?

Like.. if a user posts http://url/myphp?heybuddy=2 , you want to dynamically understand which keys were passed via get?

 

<?php

foreach($_GET as $k=>$v) {
   print "Received $k => $v <br />" ;
}

?>

<?php

if (isset($_GET['id']))
     mysql_query("DELETE FROM purchase WHERE sale_id = '{$_GET['id']}'") or die(mysql_error());

?>

Read the question first.

What I'm trying to figure out is how to see if anything has been posted, etc. to the server/page and alter what the page displays based on that information

[woodsonoversoul]

the main purpose of the page is to display a table and if the user clicks on a cell in the table, refresh the page showing all the records which also contain that information

 

code for the display

 

		echo $row[0];
	echo "<h1>category  location  price</h1>";
        echo "<table cellpadding=10 border=1>";
        while($row = $result->fetch_array()) {
            echo "<div id=\"navcontainer\">";
    	echo "<ul>";
            echo "<li><a href=#>".$row[2]."</li>";
    	echo "<li><a href=#>".$row[3]."</li>";
    	echo "<li><a href=#>$".$row[4]."</li>";
            echo "<li><a href=".$_SERVER['PHP_SELF']."?id=".$row[1].">x</a></li>";
            echo "</ul>";
		echo "</div>";

Gotta step out for a few hours.

All help is greatly appreciated
