As far as updating goes, are you actually connected to a database, I don't see mysql_connect or mysql_select_db anywhere in your code. I'd have expected to see it somewhere near where your declaring the attributes for it..

 

$db_name = "trek_trek";
$db_server = "localhost";
$db_user = "trek_user";
$db_pass = "intergreen";
// here-ish

I've already put in 'include ('testconfig.php');' and the post above shows the results with it added

 

// Check if button name "Submit" is active, do this
include ('testconfig.php');
if (isset($_POST['Update'])) {
    $sql1 = "UPDATE photo SET rank='$rank', description='$description' WHERE id=$id";
    $result1 = mysql_query($sql1) or die(mysql_error());
    if ($result1) {
        header("location:index1.php");
    }
}

 

full code:

 

<?php
error_reporting(E_ALL);
// It double checks to see if I'm logged in
require_once 'sources/login/classes/Membership.php';
$membership = New Membership();
$membership->confirm_Member();

$db_server = "localhost";
$db_user = "trek_user";
$db_pass = "intergreen";
$change = "";
$abc = "";
define("MAX_SIZE", "400");
$errors = 0;

$rank = $_POST['rank'];
$description = $_POST['description'];

Just move the if ($errors == 0) in side previous if block

            imagedestroy($tmp1);
        }
    }
}
//If no errors registred, print the success message
if ($errors == 0) {
    	$q = "INSERT into photo(description, src, tn_src) VALUES('$description', '$filename', '$filename1')";
    	//$mysqli = new MySQLi($db_server, $db_user, $db_pass, $db_name) or die(mysqli_error());
	//$result = $mysqli->query($q) or die(mysqli_error($mysqli));
	$result = mysql_query($q) or die(mysql_error());
    if ($result) {
        $change = '<div class="msgdiv">Image Uploaded Successfully!</div>';
    }
}
?>

to

            imagedestroy($tmp1);
        }
    }
//If no errors registred, print the success message
if ($errors == 0) {
    	$q = "INSERT into photo(description, src, tn_src) VALUES('$description', '$filename', '$filename1')";

awesome, nearly there  :D

 

It uploads fine and displays the thumbnails and editable descriptions, but only the original description is editable/updatable, the others don't update, so I assume there is something that needs to be done to the bit of code below to make it update all entires: 'array' / 'for each' ???

 

if (isset($_POST['Update'])) {
    $sql1 = "UPDATE photo SET rank='$rank', description='$description' WHERE id=$id";
    $result1 = mysql_query($sql1) or die(mysql_error());
    if ($result1) {
        header("location:index.php");
    }
}

 

all the code:

 

<?php
error_reporting(E_ALL);
// It double checks to see if I'm logged in
require_once 'sources/login/classes/Membership.php';
$membership = New Membership();
$membership->confirm_Member();

$db_server = "localhost";
$db_user = "trek_user";
$db_pass = "intergreen";
$change = "";
$abc = "";

$errors = 0;

$rank = $_POST['rank'];
$description = $_POST['description'];
$id = $_POST['id'];

// Check if button name "Submit" is active, do this

if (isset($_POST['Update'])) {
    $sql1 = "UPDATE photo SET rank='$rank', description='$description' WHERE id=$id";

Should be simple, *untested or proof read*

 

update form

<form method="POST" action="">
<?php
include ('testconfig.php');
$result = mysql_query("SELECT * FROM photo ORDER BY rank ASC") or die("Bad query: " . mysql_error());
while ($row = mysql_fetch_array($result))
{
    ?>
<input type="text" name="id" size="2" value="<?php print $row['id']; ?>">
<input type="text" name="rank" size="2" value="<?php print $row['rank']; ?>">
<input type="text" name="description" size="" value="<?php print $row['description']; ?>">
<?php
    echo "<img src=\"" . $row['tn_src'] . "\"/>";
    echo " <a href=delete1.php?id={$row['id']}>Delete</a><br>";
} // END WHILE
?>
<input type="submit" value="Update" name="Update">
</form>

 

to

<?php
include ('testconfig.php');
$result = mysql_query("SELECT * FROM photo ORDER BY rank ASC") or die("Bad query: " . mysql_error());
while ($row = mysql_fetch_array($result))
{
    ?>
<input type="text" name="rank[<?php print $row['id']; ?>]" size="2" value="<?php print $row['rank']; ?>">
<input type="text" name="description[<?php print $row['id']; ?>]" size="" value="<?php print $row['description']; ?>">
<?php
    echo "<img src=\"" . $row['tn_src'] . "\"/>";
    echo " <a href=delete1.php?id={$row['id']}>Delete</a><br>";
} // END WHILE
?>
<input type="submit" value="Update" name="Update">
</form>

 

and add loop

if (isset($_POST['Update'])) {
    $sql1 = "UPDATE photo SET rank='$rank', description='$description' WHERE id=$id";
    $result1 = mysql_query($sql1) or die(mysql_error());
    if ($result1) {
        header("location:index.php");
    }
}

 

to

if (isset($_POST['Update'])) {
  foreach($_POST['description'] as $id => $description){
      $rank = $_POST['rank'][$id];
      $sql1 = "UPDATE photo SET rank='$rank', description='$description' WHERE id=$id";
      $result1 = mysql_query($sql1) or die(mysql_error());
      if ($result1) {
          header("location:index.php");
      }
    }
}

Thanks MadTechie, cags, PFMaBiSmAd it's finally working, I've spent over a week trying to get it to work....

 

Here is the final code:

 

<?php

$db_pass = "intergreen";
$change = "";
$abc = "";
define("MAX_SIZE", "400");
$errors = 0;

$rank = $_POST['rank'];
$description = $_POST['description'];
$id = $_POST['id'];

// Check if button name "Submit" is active, do this
include ('testconfig.php');
if (isset($_POST['Update'])) {
  foreach($_POST['description'] as $id => $description){
      $rank = $_POST['rank'][$id];
      $sql1 = "UPDATE photo SET rank='$rank', description='$description' WHERE id=$id";
      $result1 = mysql_query($sql1) or die(mysql_error());
      if ($result1) {

      }
    }
}
