PHP Table Hyperlink - php

Question

I have a table that returns information from mysql. However, I want to hyperlink each postcode so that when the user clicks on one it will redirect them to an appropriate page. Here is the code that is in the table:
<table style="border:2px solid black; border-collapse:collapse;" cellspacing="2" cellpadding="2" align="center">
<tr align="center" width="auto">
<td bgcolor="#66CCFF" style="border:2px solid black;"><b> Consultation Date </b></td>
<td bgcolor="#66CCFF" style="border:2px solid black;"><b> Patient Health Care Number </b></td>
<td bgcolor="#66CCFF" style="border:2px solid black;"><b> Location </b></td>
<td bgcolor="#66CCFF" style="border:2px solid black;"><b> Post Code </b></td>
<td bgcolor="#66CCFF" style="border:2px solid black;"><b> Update Record </b></td>
</tr>
<?php
$i=0;
while ($i < $num) {
$f1=mysql_result($result,$i,"Consultation Date");
$f2=mysql_result($result,$i,"Patient HCN");
$f3=mysql_result($result,$i,"Location");
$f4=mysql_result($result,$i,"Post Code");
?>
<tr>
<td align="center" bgcolor="#FFFFFF" style="border:2px solid black;"><?php echo $f1; ?></td>
<td align="center" bgcolor="#FFFFFF" style="border:2px solid black;"><b><?php echo $f2; ?></b></td>
<td align="center" bgcolor="#FFFFFF" style="border:2px solid black;"><?php echo $f3; ?></td>
<td align="center" bgcolor="#FFFFFF" style="border:2px solid black;"><?php echo "<a href=\"coveragehcp.php?patient= ". $f2 ."\">"?><b><?php echo $f4; ?></b></td>
<td align="center" bgcolor="#FFFFFF" style="border:2px solid black;"><?php echo "<button onclick=\"window.location.href='hcp_form_update.php?patient=$f2'\">"?>Update Record</button></td> <!-- This button redirects the user to the auto-populated form that holds the patients information which allows the user to update it -->
</tr>
<?php
$i++;
}
?>
However when the user click on the link below I want it to redirect them to another page according to the post code clicked.
<td align="center" bgcolor="#FFFFFF" style="border:2px solid black;"><?php echo "<a href=\"coveragehcp.php?patient= ". $f2 ."\">"?><b><?php echo $f4; ?></b></td>

Answer 1

What I would do is to use the post code as a parameter in the GET, and then use the $_GET['postcode'] to achieve which page should be presented for the user.
so your PHP code for the link would look something like:
<a href=\"coveragehcp.php?patient= ".$f2."&postcode=".$f4."\">"?><b><?php echo $f4; ?></b></td>
and on the coveragehcp.php page use this
$postcode = $_GET['postcode'];
if(!empty($postcode))
{
if($postcode == 90210) {
//Echo beverly hills page
}
else {
//Echo default page
}
}
