Mysql Displaying Anything over 0

Deanznet · December 3, 2007

Hey WOrking on this item cart and its been killing me..

This is what i got it lets them buy,

Right now when they buy it adds the quanity to the person invetory. But i dosent subtract the quantity from the store.

if you know what i mean, That is their are 5 items in the store the users can keep on buying and the 5 never gose down. How would i make it run out after 5 times if ya know what i mean?

Second problem is displaying items in the store. if the quantity value is 0 than dont display anything. if its greater than 0 than display.

That code doesn't work. Wont display anything just say user not logged in.

I know the code i have works really good just need it to show items that have more than 0 in stock and update the quantity when they buy it

Deanznet · December 3, 2007

You made it so that the value for the item would post as nothing. I have fixed a couple of things including that it now checks to see if the item exists and prints how much money you have before where it tells you to buy.

I get item dosent exist.

Think is has something to do with this

function item_exists($item); dident work so i had to change it to function item_exists($item){ to make it work

	function item_exists($item){
		$item_exists_query = mysql_query("SELECT * FROM items WHERE item_name='$itemID'");
		if(mysql_num_rows($item_exists_query)>0)  {
			return TRUE;
		}
		else {
			return FALSE;
		}
	}

Deanznet · December 4, 2007

Anyone know i wanna get this part done by tonight if possible.

mr_mind · December 4, 2007

oh yes you were right. what happens when you do that?

Deanznet · December 4, 2007

I get Item does not exists

teng84 · December 4, 2007

I get item dosent exist.

Think is has something to do with this

function item_exists($item); dident work so i had to change it to function item_exists($item){ to make it work
	function item_exists($item){
		$item_exists_query = mysql_query("SELECT * FROM items WHERE item_name='$itemID'");
		if(mysql_num_rows($item_exists_query)>0)  {
			return TRUE;
		}
		else {
			return FALSE;
		}
	}

unbelievable how come you get that result out of this function when all this function do is to return true or false!!!!

Deanznet · December 4, 2007

Do what im confused Lol.. ???

teng84 · December 4, 2007

Do what im confused Lol.. ???

that code you posted (function) is boolean meaning it will only returns TRUE or FALSE based on that code! so its impossible to get that result because you can only have T/F on that function

mr_mind · December 4, 2007

It should work because i have used that exact function before except for it was users and not items. Nevertheless i have changed it to return a number which should satisfy any doubts.

If this does not work then try looking at the html output to see if everything is set correctly there

I also noticed a bug that had it checking the posted value which was an array instead of the $itemID in the foreach which i fixed try this maybe

	$user_info_query = mysql_query("SELECT * FROM phpbb_users WHERE user_id='$user_id'");
	$user_info_array = mysql_fetch_array($user_info_query);
	$user_cash = $user_info_array['user_points'];
	if($_POST['submit']) {
		if($_POST['action']=='buy') {
			$selected_array = $_POST['selected'];
			foreach($selected_array as $itemID){

Well crap i did get this

Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in
line 125
Failed connecting to the server. Please contact the site admin.

Than i added the @in front of the mysql_fetch_array looks like this now @mysql_fetch_array

Now i just get Failed connecting to the server. Please contact the site admin.

	$num_owned_query = mysql_query("SELECT * FROM user_item WHERE item_owner_id='$user_id' AND item_name='$itemID'");
						$num_owned_array = mysql_fetch_array($num_owned_query);
