I wonder whether someone could help me please.

I’m trying to put together an administration form where members records can be amended.

The code that I’ve put together is below and I can successfully retrieve the records from a mySQL database, receiving the appropriate messsage if there are no records with the email address provided.

<?php 
mysql_connect ("host","user","password") or die (mysql_error()); 
mysql_select_db ("database"); 

if ($_SERVER['REQUEST_METHOD'] == 'POST') {  
   if (isset($_POST['search'])) {
      $searchemailaddress = $_POST['searchemailaddress']; 
      $sql = mysql_query("select * from userdetails where emailaddress like '$searchemailaddress'"); 
     if (mysql_num_rows($sql) == 0)
        $msg = 'There are no member records set up with this email address, please try again!'; 
     }
     while ($row = mysql_fetch_array($sql)){ 
        $emailaddress = $row['emailaddress'];
        $forename = $row['forename']; 
        $surname = $row['surname']; 
        $subscriptionexpiration = $row['subscriptionexpiration']; 
     }
   } 
   if (isset($_POST['update'])) {
      $emailaddress = $_POST['emailaddress']; 
      $forename = $_POST['forename']; 
      $surname = $_POST['surname'];
      $subscriptionexpiration = $_POST['subscriptionexpiration']; 
      $sql = mysql_query("UPDATE `userdetails` SET `emailaddress` = '$emailaddress', `forename` = '$forename',`surname` = '$surname',`subscriptionexpiration` = '$subscriptionexpiration' LIMIT 1");
      $msg = 'This members records have been successfully updated!'; 
  }
?>

  <input type="submit" name="search" value="Search Records"> 
  <input name="update" type="submit" value="Update Record"> 
</p>
</form> 
</body> 
</html>

However, I’m having problems when I try to change any part of the record. The changes are saved and I receive the correct ‘Record updated’ message but I also receive this error:
Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /homepages/2/d333603417/htdocs/development/searchandamend.php on line 14 with line 14 being this line in my code: while ($row = mysql_fetch_array($sql)){ I’ve been working on this for a while now, and I just can’t seem to work out what the problem is.

I just wondered whether someone could perhaps take a look at this please and let me know where I’ve gone wrong.

Many thanks

    All, sincere thanks for taking the time to reply to my post.

    After looking at this a little more, and taking into account what you all said, I came up with the following which works fine.

    if ($_SERVER['REQUEST_METHOD'] == 'POST')  
{  
    if (isset($_POST["search"]))  
    {  
$searchemailaddress = $_POST['searchemailaddress'];
$result = mysql_query("select * from userdetails where emailaddress like '$searchemailaddress'");
if (mysql_num_rows($result) == 0)
$msg = 'There are no member records with the email address you have provided, please try again!'; 
else
while ($row = mysql_fetch_array($result)){ 
$emailaddress = $row['emailaddress'];
$forename = $row['forename']; 
$surname = $row['surname']; 
$subscriptionexpiration = $row['subscriptionexpiration']; 
$msg = 'Record retrieved!';
}
}

if (isset($_POST["update"]))  
    {  
$emailaddress = $_POST['emailaddress']; 
$forename = $_POST['forename']; 
$surname = $_POST['surname']; 
$result = mysql_query("UPDATE `userdetails` SET `emailaddress` = '$emailaddress', `forename` = '$forename',`surname` = '$surname', `subscriptionexpiration` = '$subscriptionexpiration' LIMIT 1");
$msg = 'This members record has been successfully updated!';
}
}

    Kind regards
