if statement

[tazgalsinh]

hi, how do i do this IF statement, when the user clicks the Finish Shopping link. If there is nothing in the cart then a message will appear saying the cart is empty but if there is then they go onto the next screen, output.php?

<td width="24%" height="25"> <font face="verdana" size="1" color="black">&nbsp; 
      <?php echo $row["ManID"]; ?> </font> </td>
    <td width="40%"><font face="verdana" size="1" color="black"> <?php echo $row["ItemName"]; ?> 
      </font></td>
    <td width="12%" height="25"> <font face="verdana" size="1" color="black"> 
      &pound; <?php echo number_format($row["itemRRP"], 2, ".", ","); ?> </font> 
    </td>
    <td width="13%" height="25"> <font face="verdana" size="1" color="black"> 
      <a href="cart.php?action=remove_item&id=<?php echo $row["itemId"]; ?>">Remove</a> 
      </font> </td>
  </tr>
  <?php
			}

		// Display the total
		?>
  <tr> 
    <td colspan="5"> <hr size="1" NOSHADE color="red"> </td>
  </tr>
  <tr> 
    <td colspan="3"> <font size="3"><a href="javascript:history.back(1)"><<---Carry 
      on Shopping </td>
    <td colspan="2"> <font face="verdana" size="2" color="black"> <b>Total: &pound;<?php echo sprintf("%1.2f", $totalCost); ?></b> 
      </font> </td>
  </tr>
  <tr>
    <td colspan="3"><a href="output.php">Finish shopping</a></td>
    <td colspan="2">&nbsp;</td>
  </tr>
</table>
			</body>
			</html>
			<?php


}

?>
<?php
mysql_free_result($Recordset1);

mysql_free_result($man);
?>

[/php}

the easiest way ist to link to output.php in any case, check in that
file if sth has been selected and forward the user respectivly

if (nothing in the cart)
{
  header ("Location: cart.php");
}
else
{
  // do stuff
}

the other way would be with javascript:
<input type=button onClick="mycheckfunction()">

in the function you can check the content (i.e. with a js variable written by PHP)
and then use the submit() method
