Question

I can’t figure why this doesn’t update my data, received from text inputs:

include "config.php"
printf ("Update PriceList\n");
printf ("<form method=\"post\" action=\"price_red.php\">");
printf ("Select PhoneID: <input type = \"Text\" name = \"PhonID\"><br>");
printf ("PhoneName:<input type = \"Text\" name = \"PhoneName\"><br>");
printf ("PhoneType:<input type = \"Text\" name = \"PhoneType\"><br>");
printf ("ScreenType:<input type = \"Text\" name = \"ScreenType\"><br>");
printf ("Camera: <input type = \"Text\" name = \"Camera\"><br>");
printf ("Quantity: <input type = \"Text\" name = \"Quantity\"><br>");
printf ("Price:<input type = \"Text\" name = \"Price\"><br>");
printf ("Out of stock:<input type = \"Text\" name = \"outofstock\"><br>");
printf ("<input type=\"Submit\" name=\"submit\" value=\"Update\">");
printf ("</form>");

$sql = mysql_query("UPDATE PhonesPriceList SET PhoneName = '$PhoneName', Price = '$Price',     Quantity = '$Quantity', Outofstock = '$outofstock' WHERE PhoneID = '$PhonID';");
$sql1 = mysql_query("UPDATE PhonesDetails SET PhoneType = '$PhoneType', ScreenType = '$ScreenType', Camera ='$Camera' WHERE PhoneID = '$PhonID';");    

Answer 1

try something like this . Just make sure you add the appropriate sanitation to prevent injection

   include "config.php"

    if(isset('submit'){
 $Phoneid= $_POST['PhoneID'];
  $Phone_name= $_POST['PhoneName'];
  $Phone_type = $_POST['PhoneType'];
  $screen_type= $_POST['ScreenType'];
  $camera = $_POST['Camera'];
   $Quantity = $_POST['Quantity'];
  $price = $_POST['Price'];
 $outofstock = $_POST['outofstock'];

$dbc = mysqli_connect( data info)
 or die ('Error connecting');
   $query = "UPDATE PhonesPriceList SET PhoneName = '$PhoneName', Price = '$price',     
      Quantity =       '$Quantity', Outofstock = '$outofstock' WHERE PhoneID = '$PhonID' ";

    msqli_query( $dbc, $query) or die (' failed to query');

   echo ' Update successful';

     mysqli_close($dbc);
  }
