hi
i am doing shopping online, i will let user choose their prodcut in the first page and then when they click" order" button, they will be redirected to do_addcart.php. i will insert their orders into "orders" table and retrieve them back and ask user to select their respective quantity and size. i have used Javascript validation:
the code is below: - <script language="JavaScript">
-
-
<!--
-
-
function validate_form ( )
-
{
-
valid = true;
-
alert (document.Lform.quantity.selectedIndex);
-
if ( document.Lform.quantity.selectedIndex == 0 )
-
{
-
alert ( "Please select your quantity!" );
-
Lform.quantity.focus();
-
valid = false;
-
}
-
else if ( document.Lform.size.selectedIndex == 0 )
-
{
-
alert ( "Please select your size!" );
-
Lform.size.focus();
-
valid = false;
-
}
-
return valid;
-
}
-
//-->
-
</script>
However, i don;t know how to correspond respective product with their respective choosen quantity and size.
the following is my current coding, - <?php
-
foreach ($_POST as $key => $value) {
-
echo "key: ".$key.", value: ".$value."<br>";
-
$sql = "INSERT INTO orders (imageid, userid, time) VALUES ('$key', '$userid', '$date')";
-
mysql_query($sql);
-
}
-
-
echo "Please select your size and quantity for purchase:";
-
echo "<table border = '1'>";
-
echo "<tr>";
-
echo "<td>Title";
-
echo "<td>Brand";
-
echo "<td>Price";
-
echo "<td>Size";
-
echo "<td>Quantity";
-

-
$sql2="SELECT imageid FROM orders";
-
$result=mysql_query($sql2);
-
while($row = mysql_fetch_array($result)) {
-
echo "<br>";
-
$sql3="SELECT brand, price, title FROM ladies WHERE id=".$row['imageid'];

hi
Orders and Ladies table is interrelated, i will insert whatever users purchases into orders table and there is imageid ( which is foreign key to Ladies table) and userid, so i will know which user choosed which item from imageid. then i use this imageid to retrieve back the value in ladies table.
the code in the first page is like this
the code in do_addcart.php is in the following: - :

There are lots of Errors in your script. - You are trying to print $quantity, $size inside the HTML(Javascript ) code
Note that PHP is executing in server side,not in the client side.if you need to print server side php varibles inside html coding, you may replace
-
document.Lform.$quantity.selectedIndex == 0
-
with this -
document.Lform.<?php $quantity ?>.selectedIndex == 0
-
And Under those list menus why is that name attribute is set to $quantity,$size . From where it is coming from?
are you planing to set the same size and quantity for all purchased item(what are those item really).

hi, in fact i was writiing a loop, but i think i delete it befoer i post, originally, i wrtie -
$quantity=0;
-
$quantity=$quantity+1; // do the same for $size;
-
i do in this is to let the drop down list of quantity and size have differe name, so that i may know which item user purchased according to which quantity and size name; something like quantity1=3, quantity2=5,etc .but finally i can not achieve it, i have only this kind of concept.is this concept correct?
in fact, i would like to know the quantity and size they choosed accorrding to the different items they buy and it is a must for them to select quantity and size from drop down list for every item they buy.
i don;t know how should i write the code so that i will know which quantity and size user selected is corresponding to which item they buy and there is also a validation so that user will not forget to select their item's quantity and size.
can help me with these part of the code, thank you very much. i am very frustrated as the project deadline is near. thank you very much for your kind help :)

Can I see the Table structure first.Then I might be able to help.
Or else go for a re-structuring you tables and Apps by your self.
Example: - From Products table list all the products to page(s) with the unique product_id
EX: 1001,1002,1003, 1004,....,n - Insert the selected products to orders table by sending the product_id to the Orders table
Ex: user select the product 1001 and 1004, then insert them to orders table. - Once you came to this stage.(update shopping cart)
User can Insert Number of Items and size for 1001 and 1004
You can put those size and Quantity in side the while loop and display the corresponding list menus for both selected products.
Ex:
1001 - size_list_menu - qty_list_menu
1004 - size_list_menu - qty_list_menu
[You can display the product Image/Name instead of Product_id to the User]
Once user select the size and Qty update them to Orders Table again.
So now for all the purchased item(s) you have.
ProductNumber
Size
Qty
That's it, Then proceed with your Payment gateway.

i think i have the same concept as you when i am doing this, but my problem is how should i validate user's selection of their selected item's size and quantity as users may forget to choose some of them. my validation now is -

however, it seems does not work at all, i think because of the naming problem. as every item is using the name of 'quantity' and 'size', so the program don;t know which quantity and size choosen is belong to which item. so how should i sovle this? this is the main problem. thanks :)
PS. my product id is atom increment, the other fields are brand, price,descripti on,etc. in my orders table, i got product id as foreign key, userid as foreign key. the rest of field is time, quantity, size.
thank you very much for your kind help. this is a bit urgent as my project's deadline is very near. if possible, please reply me ASAP. thanks:)

Since this is a shopping cart you can set some default size and Quantity for a selected item always.
Ex:
Qty always set to 1
Size set to S
For a Customer do we need to display 0 s or blanks for products, I dnt think so.Then no need of validation at all.
Still if you expecting validation just give me some times.
Thanks!

the default is all 1, but my supervisor don;t think it is practical in real life to let everyone just buy one and they should be able to select the size they wear. that is why i have to do the validation of size and quantity for each item they buy.
i have to insert their size and quanity for the respective item in database, so i have to know which size and quantity is belong to which item.
sure, i will wait for your kind reply. thanks. :)
