<style type="text/css">

<h1 align="center"><b><i>ADD NEW PRODUCT</i> </b></h1>
<p align="center">&nbsp;</p>
<form action="">
         <form action = "insertEx2.php" method = "post" >
	productID <input type = "text" name = "ID" />
	brand <input type = "text" name = "brand" />
	type <input type = "text" name = "type" />
	size <input type = "text" name = "size" />
	price <input type = "text" name = "price" />
	manufacturedate <input type = "text" name = "manufacturedate" />

	manufacture of <input type = "text" name = "manufacture of" />
	<input type = "submit" name = "submit" value = "Add New Product" />
               include 'beverage.php';		         // make db connection

		       $ID = $_POST['productID'];     //store parameters in variable
               $brand = $_POST['brand'];
               $type = $_POST['type']; 
			   $size = $_POST['size'];
			   $price = $_POST['price'];
			   $manufacturedate = $_POST['manufacturedate'];
			   $expiry  = $_POST['expirydate'];
			   $manufacture= $_POST['manufactureof'];
	$sql = "INSERT INTO product (productID, brand, type,size,price,manufacturedate,expiry date,manufactureof) values 
	('$ID','$brand','$type','$size','$price','$manufacturedate','$expiry','$manufacture','$manufacturedate','$expiry','$manufacture of')";

	mysql_query($sql) or die (mysql_error());



You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'date,manufactureof) values ('','','','','','','','','','',' of')' at line 1- this is the error i got in the form please help to rectify my mistake

Use first this to print your query:


Add this before you run the query in your code e.g. before: mysql_query($sql) or die (mysql_error());

And post that printed query here

If you observe your query in any good editor, you will see the 'missing' factor. The last variable '$manufacture of' is causing the error. A variable name cannot have a white space. For example, $variable name is NOT a valid variable name. It should be $variablename. Thats the error.
