Question

My insert and update pages (through my admin forlder) into mysql stopped working. When I try to insert/update details it stays on the same page without adding or updating anything into the database table.

I really don’t know what happened and don’t know where start looking. I didn’t make any change to the pages whatsoever.

Is there anyone who had the same problem and can kindly give me a clue?

Appreciated
Francesco

Insertng some code if it can be of nay help:

    <?php
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "") 
{
  $theValue = (!get_magic_quotes_gpc()) ? addslashes($theValue) : $theValue;

  switch ($theType) {
    case "text":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;    
    case "long":
    case "int":
      $theValue = ($theValue != "") ? intval($theValue) : "NULL";
      break;
    case "double":
      $theValue = ($theValue != "") ? "'" . doubleval($theValue) . "'" : "NULL";
      break;
    case "date":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;
    case "defined":
      $theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
      break;
  }
  return $theValue;
}

$editFormAction = $_SERVER['PHP_SELF'];
if (isset($_SERVER['QUERY_STRING'])) {
  $editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);
}

if(isset($_POST['username'])) {
mysql_select_db($database_satsconn, $satsconn);

$totalRows_rstUname = mysql_num_rows($rstUname);
if($totalRows_rstUname > 0){
$error['uname'] = 'That username is already in use. Please choose another.';
    }
}

if(isset($_POST['pwd']) && isset($_POST['pwd'])) {
 if($_POST['pwd'] != $_POST['con_pwd']) {
   $error['pwd'] = 'Your passwords don\'t match.';
   }
  else {
  $_POST['pwd'] =md5($_POST['pwd']);
  }
}

if(!isset($error)) {
if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "addUser")) {

                       GetSQLValueString($_POST['pwd'], "text"));

  mysql_select_db($database_satsconn, $satsconn);
  $Result1 = mysql_query($insertSQL, $satsconn) or die(mysql_error());
   }
}

if ((isset($_POST['members_ID'])) && ($_POST['members_ID'] != "")) {
  $deleteSQL = sprintf("DELETE FROM members WHERE members_ID=%s",
                       GetSQLValueString($_POST['members_ID'], "int"));

  mysql_select_db($database_satsconn, $satsconn);

  if (isset($_SERVER['QUERY_STRING'])) {
    $deleteGoTo .= (strpos($deleteGoTo, '?')) ? "&" : "?";

“it stays on the same page without adding or updating anything” is very common problem and can be caused by thousands of errors. There is noway to solve it by finding “anyone who had the same problem”.

If you’re just user of this code, it would be better to hire a programmer.

If you supposed to be a programmer yourself, you have to learn how to debug your application. Debugging stands for finding where the error is. Although debugging could help only if you know, what your code does. You can try it anyway.

There are many things to do. You have to be sure that you can see all possible errors.
