Dynamic Form Menu

Hello,

I'm trying to put a dynamic form menu within a repeating section, in order to give the option to choose sizes. The sizes vary for each individual item (they change from item to item) and I'm having trouble setting up my recordset and menu to show the appropriate choices. I have 3 tables - an item table, an option table with the sizes, and an intermediate itemoption table linking the two tables. I want this information to be passed to ecart.

This is how I set up the recordset (which I suspect is wrong):

$varItem_rsSizes = "1";
if (isset($_GET['ItemID'])) {
$varItem_rsSizes = $_GET['ItemID'];
}
mysql_select_db($database_connSpectrum, $connSpectrum);
$query_rsSizes = sprintf("SELECT items.ItemID, options.OptionID, options.Option, options.OptionPrice, options.OptionWeight FROM items LEFT OUTER JOIN itemoptions ON items.ItemID = itemoptions.ItemID INNER JOIN options ON itemoptions.OptionID = options.OptionID WHERE items.ItemID = %s", GetSQLValueString($varItem_rsSizes, "int"));
$rsSizes = mysql_query($query_rsSizes, $connSpectrum) or die(mysql_error());
$row_rsSizes = mysql_fetch_assoc($rsSizes);
$totalRows_rsSizes = mysql_num_rows($rsSizes);
?>

And this is the form:

<form id="form1" name="form1" method="post" action="">
<label for="sizes">Sizes & Prices:</label>
<select name="sizes" id="sizes">
<option value="null" <?php if (!(strcmp("null", $row_rsItems['ItemID']))) {echo "selected=\"selected\"";} ?>>--Please select a size--</option>
<?php
do {
?>
<option value="<?php echo $row_rsSizes['OptionID']?>"<?php if (!(strcmp($row_rsSizes['OptionID'], $row_rsItems['ItemID']))) {echo "selected=\"selected\"";} ?>><?php echo $row_rsSizes['Option']?></option>
<?php
} while ($row_rsSizes = mysql_fetch_assoc($rsSizes));
$rows = mysql_num_rows($rsSizes);
if($rows > 0) {
mysql_data_seek($rsSizes, 0);
$row_rsSizes = mysql_fetch_assoc($rsSizes);
}
?>
</select>
</form>

Can anyone tell me how to fix this from within Dreamweaver's interface?

Thanks!

this will require some rearranging of the code.

first, instead of using the $_GET['ItemID'] as the run time value for the varItem parameter, you need to use the ItemID from the main recordset $row_rsItems['ItemID']


Second, the code for the rsSizes recordset needs to be moved so that it is inside the repeat region.

Hi Jason,

Thanks so much for the help!

I changed the run time value for the varItem parameter as follows:

$varItem_rsSizes = "1";
if (isset($row_rsItems['ItemID'])) {
$varItem_rsSizes = $row_rsItems['ItemID'];

I'm not quite sure what you mean by moving the rsSizes recordset code inside the repeat region. Could you explain what you mean? Dreamweaver inserted it for me.

The recordset code will be created in the head of the page before the doc type tag.

Since you want to create a unique record set for each product that is being displayed, the recordset code will need to be moved so that it is inside the repeat region.

if you need more specifics than that, please send a copy of your page.

Hi Jason,

This is a bare-bones page to test the code on before I add a cart to my product pages.
I'm also trying to figure out how to add the individual sizes and prices into the repeating section underneath the item description, but it won't allow "nesting".

<?php require_once('Connections/connSpectrum.php'); ?>
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "")
{
if (PHP_VERSION < 6) {
$theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
}

$theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);

switch ($theType) {
case "text":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "long":
case "int":
$theValue = ($theValue != "") ? intval($theValue) : "NULL";
break;
case "double":
$theValue = ($theValue != "") ? doubleval($theValue) : "NULL";
break;
case "date":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "defined":
$theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
break;
}
return $theValue;
}
}

mysql_select_db($database_connSpectrum, $connSpectrum);
$query_rsItems = "SELECT ItemID, ItemCatID, ItemName, ItemDesc, ItemSKU, ItemImage, FROM items ORDER BY ItemID ASC";
$rsItems = mysql_query($query_rsItems, $connSpectrum) or die(mysql_error());
$row_rsItems = mysql_fetch_assoc($rsItems);
$totalRows_rsItems = mysql_num_rows($rsItems);

$varItem_rsSizes = "1";
if (isset($row_rsItems['ItemID'])) {
$varItem_rsSizes = $row_rsItems['ItemID'];
}
mysql_select_db($database_connSpectrum, $connSpectrum);
$query_rsSizes = sprintf("SELECT items.ItemID, options.OptionID, options.Option, options.OptionPrice, options.OptionWeight FROM items LEFT OUTER JOIN itemoptions ON items.ItemID = itemoptions.ItemID INNER JOIN options ON itemoptions.OptionID = options.OptionID WHERE items.ItemID = %s", GetSQLValueString($varItem_rsSizes, "int"));
$rsSizes = mysql_query($query_rsSizes, $connSpectrum) or die(mysql_error());
$row_rsSizes = mysql_fetch_assoc($rsSizes);
$totalRows_rsSizes = mysql_num_rows($rsSizes);
?>

Thanks so much!

so, this line begins the repeat region:
<?php do { ?>

the recordset needs to be after that line:

<?php do { ?>
<?php
$varItem_rsSizes = "1";
if (isset($row_rsItems['ItemID'])) {
$varItem_rsSizes = $row_rsItems['ItemID'];
}
mysql_select_db($database_connSpectrum, $connSpectrum);
$query_rsSizes = sprintf("SELECT items.ItemID, options.OptionID, options.Option, options.OptionPrice, options.OptionWeight FROM items LEFT OUTER JOIN itemoptions ON items.ItemID = itemoptions.ItemID INNER JOIN options ON itemoptions.OptionID = options.OptionID WHERE items.ItemID = %s", GetSQLValueString($varItem_rsSizes, "int"));
$rsSizes = mysql_query($query_rsSizes, $connSpectrum) or die(mysql_error());
$row_rsSizes = mysql_fetch_assoc($rsSizes);
$totalRows_rsSizes = mysql_num_rows($rsSizes);
?>

Hi Jason,

Thanks so much, it works perfectly!
