I am trying to display all the records from a mysql database in a table and have the results all editable.  I want to be able to edit the records right in the table.  I can display the data but not edit it.  How do I do this?

Hi, after changing the values, you need to submit it, and update the table...

        $sql = "UPDATE mytable ...";
        mysql_query($sql) or die(mysql_error());

    <INPUT ...>
    <INPUT TYPE="hidden" NAME="update">
    <SUBMIT ...>

Once the table is displayed, I can't change any values.  They are not editable.

Well, how are you displaying it ?


while($row = mysql_fetch_array($result))

<TD> <INPUT TYPE="text" NAME="col1<?=$i?>" VALUE="<?=$row['col1']?>"> </TD>
<TD> <INPUT TYPE="text" NAME="col2<?=$i?>" VALUE="<?=$row['col2']?>"> </TD>

I am using dreamweaver and putting code together from other pages.  I am now able to display all the data in a table and edit it.  However, when I update the table,after making changes,  all the entries in the database are changed to the last entry.  So all entries are the same.  It is completely screwed up.  I'll show you the code here,

<?php require_once('Connections/connsearch.php'); ?>
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "")
  $theValue = (!get_magic_quotes_gpc()) ? addslashes($theValue) : $theValue;

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

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

if ((isset($_POST["MM_update"])) && ($_POST["MM_update"] == "form1")) {
  $updateSQL = sprintf("UPDATE table1 SET scottid=%s,companyname=%s, addressline1=%s, addressline2=%s, city=%s, province=%s, postalcode=%s, telephone=%s, fax=%s, website=%s, email=%s, subscription=%s WHERE scottid=%s",
                       GetSQLValueString($_POST['scottid'], "text"),  
                       GetSQLValueString($_POST['companyname'], "text"),
                       GetSQLValueString($_POST['addressline1'], "text"),
                       GetSQLValueString($_POST['addressline2'], "text"),
                       GetSQLValueString($_POST['city'], "text"),
                       GetSQLValueString($_POST['province'], "text"),
                       GetSQLValueString($_POST['postalcode'], "text"),
                       GetSQLValueString($_POST['telephone'], "text"),
                       GetSQLValueString($_POST['fax'], "text"),
                       GetSQLValueString($_POST['website'], "text"),
                       GetSQLValueString($_POST['email'], "text"),
                       GetSQLValueString($_POST['subscription'], "text"));

  mysql_select_db($database_connsearch, $connsearch);
  $Result1 = mysql_query($updateSQL, $connsearch) or die(mysql_error());

  $updateGoTo = "confirmation.html";
  if (isset($_SERVER['QUERY_STRING'])) {
    $updateGoTo .= (strpos($updateGoTo, '?')) ? "&" : "?";
    $updateGoTo .= $_SERVER['QUERY_STRING'];
  header(sprintf("Location: %s", $updateGoTo));

mysql_select_db($database_connsearch, $connsearch);
$query_rseditmachines = "SELECT * FROM table1";
$rseditmachines = mysql_query($query_rseditmachines, $connsearch) or die(mysql_error());
$row_rseditmachines = mysql_fetch_assoc($rseditmachines);
$totalRows_rseditmachines = mysql_num_rows($rseditmachines);

      <td><input type="text" name="subscription" value="<?php echo $row_rseditmachines['subscription']; ?>"></td>
    <?php } while ($row_rseditmachines = mysql_fetch_assoc($rseditmachines)); ?>
  <input type="hidden" name="MM_update" value="form1">
  <input type="submit" value="Update record">

It probably looks like a mess as I have heard that dreamweaver gives some awful code sometimes.  Suggestions on changes or a complete overhaul would be appreciated

you need to pass primary key value to the update query. store primary key for example id in the hidden field in html form. and on the update page make the query something like

mysql_query("update table set field1='value 1' where id='".$_POST["hidden_id"]."');

you should use ajax with editcontentable feature of each div to access table content if you wont use input text... If you will use input and you dont have any idea with ajax then you can write a code like mine below. It creates an image and i send it data with its src property.

function sendNew(sendData,where,id){
      a = new Image();
<input name="" type="text" onClick="sendNew(this.value,'fieldname',1)">
