Hello,

 

I am quite new using php and I have mostly been working with Dreamweaver built in features. I've managed to create a simple update form, but to be honest, I don't master it, it's all automatic functions. The form works ok for the display/detail forms, but only for the first record. When I try to update the rest of them, the record update form always shows the first record. What am I doing wrong???

 

You can see an example here:

Codes:

 

master.php file:

 

<?php require_once('Connections/conn2.php'); ?>
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "") 
{
  $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;

  $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($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;
}
}

$currentPage = $_SERVER["PHP_SELF"];

$maxRows_Recordset1 = 10;
$pageNum_Recordset1 = 0;
if (isset($_GET['pageNum_Recordset1'])) {
  $pageNum_Recordset1 = $_GET['pageNum_Recordset1'];
}
$startRow_Recordset1 = $pageNum_Recordset1 * $maxRows_Recordset1;

mysql_select_db($database_conn2, $conn2);
$query_Recordset1 = "SELECT * FROM colores";
$query_limit_Recordset1 = sprintf("%s LIMIT %d, %d", $query_Recordset1, $startRow_Recordset1, $maxRows_Recordset1);
$Recordset1 = mysql_query($query_limit_Recordset1, $conn2) or die(mysql_error());
$row_Recordset1 = mysql_fetch_assoc($Recordset1);

if (isset($_GET['totalRows_Recordset1'])) {
  $totalRows_Recordset1 = $_GET['totalRows_Recordset1'];
} else {
  $all_Recordset1 = mysql_query($query_Recordset1);
  $totalRows_Recordset1 = mysql_num_rows($all_Recordset1);
}
$totalPages_Recordset1 = ceil($totalRows_Recordset1/$maxRows_Recordset1)-1;

if (!empty($_SERVER['QUERY_STRING'])) {
  $params = explode("&", $_SERVER['QUERY_STRING']);
  $newParams = array();
  foreach ($params as $param) {

        stristr($param, "totalRows_Recordset1") == false) {
      array_push($newParams, $param);
    }
  }
  if (count($newParams) != 0) {
    $queryString_Recordset1 = "&" . htmlentities(implode("&", $newParams));
  }
}
$queryString_Recordset1 = sprintf("&totalRows_Recordset1=%d%s", $totalRows_Recordset1, $queryString_Recordset1);

Sorry for the long codes. Someone told me it had to be somewhere here:

 

$query_Recordset1 = "SELECT * FROM colores";

 

I've try this:

 

$value= $_GET['id'];

$query_Recordset1 ="SELECT * FROM colores WHERE id='".$value."'";

 

But still doesn't work. The "id" value is not passing from the previous page (detail.php) to the last page (updat.php)

 

 

Thank you very much

 

Eduardo

it because of this loop i am sure of it......

 

 

  $totalRows_DetailRS1 = mysql_num_rows($all_DetailRS1);

 

try different looping method...

 

why i say that..

 

  <td>id</td>

    <td><?php echo $row_DetailRS1['id']; ?> </td>

  </tr>

  <tr>

    <td>cosa</td>

    <td><?php echo $row_DetailRS1['cosa']; ?> </td>

  </tr>

  <tr>

    <td>numero</td>

    <td><?php echo $row_DetailRS1['numero']; ?> </td>

  </tr>

</table>

 

THE LOOP WORKS ABOVE BUT NOT NOW ONWARDS?(( YOU SHORT HANDED THE LOOP WHY?  }>STOOPED IT WHY?

 

<p><a href="update.php?<?php echo $row_DetailRS1['id']; ?>=<?php echo $row_DetailRS1['id']; ?>">Update</a></p>

</body>

As I said before, I didn't write this code, I used Dreamweaver built in features. So, please, forgive my ignorance... and I don't really get what you are saying...that's way too complicated for me, but I'll try to read slowly so I can get it.

 

Thanks

Eduardo

So you say this line is wrong?:

 

<p><a href="update.php?<?php echo $row_DetailRS1['id']; ?>=<?php echo $row_DetailRS1['id']; ?>">Update</a></p>

 

What should I put then?

 

Look, all I need is a very simple  insert / update / delete form for very simple records (something like name, last name, comments). Do you know a good tutorial where I could learn that?. I have books but they all use very complex examples, using multiple tables, etc. I just need a simple table with 3 columns.

 

Thanks

 

Eduardo
