Hi Everyone
I am working through a book called Dreamweaver PHP Web Development. It has a tutorial for creating a booking system for a hotel. The because went out of publication in 2002 and there isn't a errata on the Glasshaus site for it . When creating the search page I am getting the following error message. Warning: mysql_fetch_assoc(): 2 is not a valid MySQL result resource. The page is only showing one result and I think that the error message has something to do with that.
The code for the page is as follows
<?php require_once('Connections/conn1.php'); ?>
<?php
if($_POST['bed_option'] == "less")
{
$bcomp = "<";
}
else if($_POST["bed_option"] == "more")
{
$bComp = ">";
}
else
{
$bComp = "=";
}
?>
<?php
if($_POST["price_option"] == "above")
{
$pComp = ">";
}
else
{
$pComp = "<=";
}
?>
<?php
$bedComp_rsSearch = "<";
if (isset($bComp)) {
$bedComp_rsSearch = (get_magic_quotes_gpc()) ? $bComp : addslashes($bComp);
}
$bedNum_rsSearch = "0";
if (isset($_POST['bed'])) {
$bedNum_rsSearch = (get_magic_quotes_gpc()) ? $_POST['bed'] : addslashes($_POST['bed']);
}
$pComp_rsSearch = "<=";
if (isset($pComp)) {
$pComp_rsSearch = (get_magic_quotes_gpc()) ? $pComp : addslashes($pComp);
}
$pNum_rsSearch = "0";
if (isset($_POST['price'])) {
$pNum_rsSearch = (get_magic_quotes_gpc()) ? $_POST['price'] : addslashes($_POST['price']);
}
mysql_select_db($database_conn1, $conn1);
$query_rsSearch = sprintf("SELECT ID, price, bed, number FROM room WHERE bed %s %s AND price %s %s", $bedComp_rsSearch,$bedNum_rsSearch,$pComp_rsSearch,$pNum_rsSearch);
$rsSearch = mysql_query($query_rsSearch, $conn1) or die(mysql_error());
$row_rsSearch = mysql_fetch_assoc($rsSearch);
$totalRows_rsSearch = mysql_num_rows($rsSearch);
?>
<form name="form1" method="post" action="search.php">
<table width="400" border="0">

</form>
<?php
mysql_free_result($rsSearch);
?>
<table width="50%" border="0" cellspacing="0" cellpadding="0">

<?php do { ?>
<tr>
[B]<td><font size="2" face="Verdana, Arial, Helvetica, sans-serif"> <?php echo $row_rsSearch['ID']; ?></font></td>

</tr>
<?php } while ($row_rsSearch = mysql_fetch_assoc($rsSearch)); ?>
</table>
<p> </p>
The error message says line 100 which is in the bold part of the code. Hope someone can explain what the error message means and how to fix it.
Thanks Lynne
