Body
<p>I'm unable to figure out how to implement a join in this code. Also a second issue is that I want to use <code>'Charity No: '.$don['charity_id'].'<br/>'.</code> in the mysql_query <code>("SELECT * FROM charity where id='?????????'")</code></p> <p>What the code does now is it retrieves all this data which is fine, but I want charity_id[FK](which is in the donation table) as charityname(from the charity table) instead, and im sure this is done using a join but can't figure out how to do this in my code. The second issue is that I want to create a rating system that rates the charity (based on the charity number) the data is literraly a few lines above but I can't figure this out either. </p> <p>My code is:</p> <pre><code><?php if (!isset($_POST['do']) || !isset($_POST['id']) || !$_POST['id']) exit; require_once 'connection.php'; $don=mysql_fetch_assoc( mysql_query('SELECT * FROM donation WHERE id="'.mysql_real_escape_string($_POST['id'],$con).'"',$con)); if ($don===false || !$don['id']) print '<h3>Donation id #'.$_POST['id'].' does not exist!</h3>'; else { print '<h3>Information about donation id #'.$_POST['id'].'</h3>'. 'Donor ID: '.$don['donor_id'].'<br/>'. 'Charity No: '.$don['charity_id'].'<br/>'. 'Date & Time: '.$don['TransactionTime'].'<br/>'. 'Donation Amount: £ '.number_format($don['D_Amount'],2).'<br/>'. } $find_data = mysql_query("SELECT * FROM charity where id='?????????'"); while($row = mysql_fetch_assoc($find_data)) { $id = $row['id']; $C_Name = $row['CharityName']; $C_Desc = $row['CharityDescription']; $Hits = $row['Hits']; $Ranking = $row['Ranking']; echo " <form action='rate.php' method='POST'> $C_Name: <select name='Ranking'> <option>1</option> <option>2</option> <option>3</option> <option>4</option> <option>5</option> </select> <input type='hidden' value=$id name='ID'> <input type='submit' value='Rate'>; </form> "; } </code></pre> <p>The JOIN I tried now is:</p> <pre><code>$don=mysql_fetch_assoc( mysql_query('SELECT * FROM donation As D JOIN charity as C ON d.charity_id=C.id WHERE id="'.mysql_real_escape_string($_POST['id'],$con).'"',$con)); </code></pre> <p>But now luck.</p> <p>Any help given would be highly appreciated, Thanks.</p>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
