Problem pulling data from record set

Problem pulling data from record set

When I add a dynamic add to cart button, I don't get the information for the data set for my shopping cart.

First I attached the recordset1 to the product result page:

Here is the code that I set the filter for form variable = ID: When I test it with ID= 101 it pulls up the information correctly.

<?php
//WA eCart Include
require_once("WA_eCart/eCart1_PHP.php");
?>
<?php require_once('Connections/bearpawwdcostdb.php'); ?>
<?php
$eCart1->GetContent();
?>
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($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;
}
}

$colname_Recordset1 = "-1";
if (isset($_POST['ID'])) {
$colname_Recordset1 = (get_magic_quotes_gpc()) ? $_POST['ID'] : addslashes($_POST['ID']);
}
mysql_select_db($database_bearpawwdcostdb, $bearpawwdcostdb);
$query_Recordset1 = sprintf("SELECT * FROM producttable1 WHERE ID = %s", GetSQLValueString($colname_Recordset1, "int"));
$Recordset1 = mysql_query($query_Recordset1, $bearpawwdcostdb) or die(mysql_error());
$row_Recordset1 = mysql_fetch_assoc($Recordset1);
$totalRows_Recordset1 = mysql_num_rows($Recordset1);
?>
<?php
// WA eCart Redirect
if ($eCart1->redirStr != "") {
header("Location: ".$eCart1->redirStr);
}
?>


Next I insert the dynamic add to cart button with the ID value = 101

Here is the add to cart button cord:

<form name="eCart1_1_ATC_<?php echo $row_Recordset1["101"]; ?>" method="POST" action="<?php echo $_SERVER["PHP_SELF"]; ?><?php echo (isset($_SERVER["QUERY_STRING"]) && $_SERVER["QUERY_STRING"] != "")?"?".$_SERVER["QUERY_STRING"]:""; ?>">
<input type="hidden" name="eCart1_1_ID_Add" value="<?php echo $row_Recordset1["101"]; ?>" >
<input type="text" name="eCart1_1_Quantity_Add" value="1" size="4" >
<input type="image" src="WA_eCart/Images/Deep Jungle/Btn2_EN_addtocart.gif" border="0" class="eC_ImageButton" value="Add to Cart" name="eCart1_1_ATC">
</form>




But when I run the page and try to add the 101 product to my cart, nothing happens.

To test the page and shopping cart links, I set it up as a static button with all the information and the cart worked perfectly.

So why won't the dynamic add to cart button read the info from my record set and insert it into my shopping cart.

change:
<input type="hidden" name="eCart1_1_ID_Add" value="<?php echo $row_Recordset1["101"]; ?>" >


to:
<input type="hidden" name="eCart1_1_ID_Add" value="101" >

Can't get data

That is the way I originally wrote the code and it didn't work. I did it again and it still doesn't work.

?

your product recordset is filtered on a posted form element named ID which does not exist when the add to cart button is pressed.


normally, a product detail page would use a querystring variable instead of a posted form variable.

change:
<input type="hidden" name="eCart1_1_ID_Add" value="101" >

to:
<input type="hidden" name="eCart1_1_ID_Add" value="101" >
<input type="hidden" name="ID" value="101" >

That worked perfect. However, I don't understand why. Is it because when the add to cart button is pressed, then the posted form element ID is created. Is that why I need both lines:


<input type="hidden" name="eCart1_1_ID_Add" value="101" >
<input type="hidden" name="ID" value="101" >

because it is querying for the value in the first line and the second line creates the ID = 101?


I am just trying to understand this so that I don't make the mistake again.


You and this forum are a great help to us less knowledgeable in php code.

normally the second line would not be needed if the detail page where set to use a querystring variable.

your detail page is set to use a posted value, so the posted value needs to be included in the add to cart form.
