Hi.

Is this the query you want to edit and put WHERE caluse :

$sql = "SELECT `Product_Name`, `Product_Description`, `Product_Picture`, `Product_price`, `Product_Category`, `Product_Pdf`, `Product_Cart`, `Product_Features`, `Product_subcat`, `Key` FROM `prod_listing`";

Hi.

Is this the query you want to edit and put WHERE caluse :

$sql = "SELECT `Product_Name`, `Product_Description`, `Product_Picture`, `Product_price`, `Product_Category`, `Product_Pdf`, `Product_Cart`, `Product_Features`, `Product_subcat`, `Key` FROM `prod_listing`";

To my knowledge i need to change both queries as 1 is the record count & the other is the records!!

Hi again.

I cannot understand what's the problem to add WHERE clause to the queries ?

$query = " SELECT ........ FROM table WHERE Product_Category = 'Acoustic treatment'; "

You haven't shown us where you want to include a where clause. You should mention your problem in detail. :)

Im using PHP5 fast & Easy by Julie Meloni to create a database.

I have this error on my data update page:

"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 'WHERE id ='_POST[id]'' at line 9"

This is my code:

<?
session_start();
//check for required form variables
if ((!$_POST[first]) || (!$_POST[last])) {
    header("Location:http://www.myweb.com/database2/pick_modcontact.php");
    exit;
} else {
    //if form variables are present,start a session
    session_start();
}
//check for validity of user
if ($_SESSION[valid] != "yes"){
    header("Location:http://www.myweb.com/database2/contact_menu.php");
    exit;
}

//set up table and database names
include("dbinfo.inc.php");

//connect to server and select database
$connection = @mysql_connect($hostname,$username,$password) or die(mysql_error());
$db = @mysql_select_db($dbname,$connection) or die(mysql_error());

//build and issue query
$sql ="UPDATE $usertable SET
    first ='$_POST[first]',
    last ='$_POST[last]',
    homeph ='$_POST[homeph]',
    cellph ='$_POST[cellph]',
    fax ='$_POST[fax]',
    email ='$_POST[email]',
    web ='$_POST[web]',
    [COLOR="Red"]WHERE id ='_POST[id]'";[/COLOR]

$result = @mysql_query($sql,$connection) or die(mysql_error());
?>

I have PHP version 4.3 and mySQL 4.1

Any suggestions?
