Include different mysql data on a page based on the users choice - php

Question

I have a problem here I can't solve. I have a database of houses with country, location, price etc entities. I print only the countries in a table using:
while ($data = mysql_fetch_array($select))
where $select is a query that selects specific data from the db. I want to display the full information of the selected db data on a different page i have created. The problem is that i don't know how to take the price of the data the user selected. When i get the price of the $_SESSION['counter'], its the number of the last entity of the db. . I don't want to use javascript etc. Here's the code of the page:
<?php
require_once 'php/core.php'; // opens the database
require_once 'php/openDB.php'; // starts the new session
$select = mysql_query("SELECT ID, Country, City FROM Houses");
$counter = 1;
echo "<form action='house_profile.php' method='get'>
<table width='400'>
<tr>
<td>No.</td>
<td>Country</td>
<td>City</td>";
echo "<tr>";
while ($data = mysql_fetch_array($select))
{
echo "<tr>";
echo "<td>" . $counter . "</td>";
echo "<td>" . $data['Country'] . "</td>";
// echo "<td>" . "<a href='house_profile.php' type='submit' value='$counter'>" . $data['City'] . "</a>" . "</td>";
echo "<td>" . $data['City'] . "</td>";
echo "<td><input type='submit' value='info' name='" . $counter . "'></td>";
echo "</tr>";
$_SESSION['counter'] = $counter;
$counter++;
}
echo "</table>
</form>";
?>`

Answer 1

Clarification:
You can pass any value to house_profile.php by adding a ? to start the querystring, then the name of the variable and the value. If you want to pass the id to house_profile then the link should look like this.
"<a href='house_profile.php?ID=" . $data['ID'] . "'>"
then in house_profile.php update your query like this
$select = mysql_query("SELECT * FROM Houses where ID = " . $_GET['ID']);
Now only the entity they clicked will be available.
FYI $counter is just the count, it's not necessarily the ID of the entity. e.g. if you delete ID 1 your records will start from ID 2 but counter will always start with 1. So to reference your entities correctly use the database ID.

Answer 2

Your query retrieves each house's ID from the database but doesn't display this (unless I don't understand your code). When the user chooses a house, you have to retrieve the ID and then use this in a separate query, such as
select price
from houses
where id = :ID
Currently you're displaying a line counter on your form as opposed to the house's ID - which explains why you write...
When i get the price of the $_SESSION['counter'], its the number of the last entity of the db.
You're passing the value of the row counter to the second query instead of the house's ID.
