mikosiko Posted May 18, 2011 Share Posted May 18, 2011 part of your code: $query("SELECT products.name AS name, products.price AS price, addtionalCategories.productID AS productID FROM products, addtionalCategories WHERE category='$cat' AND products.id = addtionalCategories.productID"); while($fetch=mysql_fetch_object($query)){ read... and compare your code to the examples http://php.net/manual/en/function.mysql-query.php Quote Link to comment Share on other sites More sharing options...
Orionsbelter Posted May 18, 2011 Author Share Posted May 18, 2011 silly newbie mistake <?php $query=mysql_query("SELECT products.name AS name, products.price AS price, addtionalCategories.productID AS productID FROM products, addtionalCategories WHERE category='1' AND products.id = addtionalCategories.productID"); while($fetch=mysql_fetch_object($query)){ echo"$fetch->name"; } ?> however it still echos only the following id departmentID categoryID subcategoryID productID Quote Link to comment Share on other sites More sharing options...

mikosiko Posted May 18, 2011 Share Posted May 18, 2011 <body> <?php $query("SELECT products.name AS name, products.price AS price, addtionalCategories.productID AS productID FROM products, addtionalCategories WHERE category='$cat' AND products.id = addtionalCategories.productID"); while($fetch=mysql_fetch_object($query)){ echo"$fetch->name"; } ?> this is your full code? .... and what else have you tried?... what results are you expecting? according to one of your posts: however it still echos only the following id departmentID categoryID subcategoryID productID I don't see anything like that in your code... only one echo"$fetch->name" ??

Orionsbelter Posted May 18, 2011 Author Share Posted May 18, 2011 my full code is <?php session_start(); $username=$_SESSION['username']; include_once"../includes/db_connect.php"; $cat=$_GET['cat']; ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> </head> <body> <?php $query=mysql_query("SELECT products.name AS name, products.price AS price, addtionalCategories.productID AS productID FROM products, addtionalCategories WHERE products.category='1' AND products.id = addtionalCategories.productID"); while($fetch=mysql_fetch_object($query)){ echo"$fetch->name"; } ?> </body> </html> i'm trying to display all my products by name from my mysql database however i two tables one which is products which contains the master category in a field called category and another table which is called additionalCategories which contains a field called productID which is the same as a record in the products table i use the id field in the products table and inset into additonalCategories to allow myself to add products to more than one categories however when i try join the too so i can display all products in the category from the products table and all products from additionalCategories. however it isn't displaying anything.

mikosiko Posted May 18, 2011 Share Posted May 18, 2011 I did post ONLY your relevant code ... the one that is supposed to "display" your data.... and I still seeing only ONE echo there... if that piece of (incomplete) code is not displaying anything means that your query is not returning anything or is failing... or you are not connected to the DB... try this simple changes (very dirty... just to help you to start) : $query = "SELECT products.name, products.price, addtionalCategories.productID FROM products, addtionalCategories WHERE products.category='1' AND products.id = addtionalCategories.productID"; $query = mysql_query($query) or die("error : " . mysql_error()); while( $fetch = mysql_fetch_object($query)){ echo "Product Name : " . $fetch->name; echo "<br />Product Price : " . $fetch->price; // etc... etc...etc... } see what you get from this Quote Link to comment Share on other sites More sharing options...
Orionsbelter Posted May 19, 2011 Author Share Posted May 19, 2011 thanks for replying, however it still doesn't shows anything it isn't reporting any mysql_errors either Quote Link to comment Share on other sites More sharing options...
mikosiko Posted May 19, 2011 Share Posted May 19, 2011 if you replace this line: $query = mysql_query($query) or die("error : " . mysql_error()); with this: $query = mysql_query($query) or die("error : " . mysql_error()); $num_rows = mysql_num_rows($query); echo "Rows Returned by the Query : " . $num_rows; what do you get?
