Help with $_GET Function

I'm building an online game as a poject at the moment, for one of the pages, it allows to user to purchase units spending there gold and turns. I have a table with a form outputting the unit data from an SQL Database as an array, so whenever i add a new unit onto the database, it will appear on the list.

This is the code so far:

<?php
while($table = mysql_fetch_array($units2)){
?>
<tr>
<td width="68" align="center"><?php echo $table['name']; ?>
</td>
<td width="58" align="center"><?php echo $table['price']; ?>
</td>
<td width="100" align="center"><input name="<?php echo $table['name']; ?>" type="text" id="<?php echo $table['id']; ?>" size="2" maxlength="4"></td>
</tr>
<?php
}
?>
<tr>
<td><input name="Submit" type="submit" id="Submit" value="Buy Units"></td>
</tr>
</table>
</form>



Now my question is, how can i gather the data from the form when it submits. I know how to do the old $_GET feature, but as the table is dynamic and an array, its always changeing.

how can i make a list of $_GET's pulling the ID Details off the SQL Database?

 

There are a few options you could do, a simple one would be to create a hidden form field with all the IDs you need to process when it's submitted.

<input type="hidden" name="myIds" value="1,2,3,4,5" /> // use PHP to print out the value field


Then when the form is submitted on the PHP side

if(isset($_POST['myIds'])){
	$myIds = explode(",", $_POST['myIds']);
	foreach($myIds as $index=>$myId){
		if(isset($_POST[$myId])){
			// validate that myId is a valid id, like an int or something
			
			// process the data from the form
		}
	}
}
