I have an online photogallery nearly working. I get the error below and have no idea why its happening. The 'Still Here!' bit is what the code is echoing so i can see if that set of code works. I have followed a tutorial for this and Not really sure what to do.

 

Still here!

Fatal error: Call to undefined function: insert_location() in /homepages/12/d214897219/htdocs/adam/create_thumbnails.php on line 48

 

This is the create-thumbnails code

<?php
include("GallerySizer.php");
include("config.php");
DEFINE("IMAGE_FULL", '../adam/photos/');

//database connect


$db_server ="this is correct";     
$db_user = "this is correct";    
$db_pass = "this is correct";     
$db_name = "this is correct";
$con = mysql_connect("$db_server","$db_user","$db_pass");

// Album cover
$cover = $_FILES['image']['name'][$_POST['album_cover']];
if (!$_REQUEST['process']){
echo("Error! No images chosen for processing. <br />");
echo("Click <a href='index.php'>here</a> to start processing your images.");
die();
} elseif (!$_POST['album_id']){
echo("No album selected. Please <a href=\"\">choose an album</a> to upload images to.");
die();
} else {
for($i = 0; $i < count($_FILES['image']['tmp_name']); $i++){
$fileName = $_FILES['image']['name'][$i];
copy($_FILES['image']['tmp_name'][$i], IMAGE_FULL . $fileName);
$thumb = new GallerySizer();
if($thumb->getLocation($_FILES['image']['name'][$i])){
if($thumb->loadImage()){
echo("Still here!");
if($thumb->getSize()){
if($thumb->setThumbnail()){
if($thumb->copyThumbImage()){
if($thumb->resizeImage()){
$thumb->copyResizedImage();

}
}
}
}
}
else {
echo("Invalid image/file has been uploaded. Please upload a supported file-type (JPEG/PNG)"); 
unlink(IMAGE_FULL . $fileName);
die();
}
insert_location($thumb);

}
} 


//insert image
function insert_location($thumb_obj)
{

$image_location = $thumb_obj->getImageLocation();
$thumb_location = $thumb_obj->getThumbLocation();

// If image matches cover selection, update album cover
if($cover == $_FILES['image']['name'][$i]){
	$sql = "UPDATE albums SET album_cover = '" . $thumb_location . "' WHERE album_id = " . $_POST['album_id'];
	$result = @mysql_query($sql) or die("Error inserting records: " . mysql_error());
}

mysql_select_db("db218351273", $con);
$sql = ("INSERT INTO photos (photo_id, photo_title, photo_desc, photo_date, photo_location, thumbnail_location,album_id)

Man you totally messed up your code- have you noticed that the function is being defined inside the "else" that starts in line 24? Or that your for loop starts in line 25 and ends in line 51?

The code is a total mess. Start using tabbing and other spacing. I'd also recommend you to use a text editor that has some highlighting, I personally use Notepad++.

After you clean up your code and fix all of the brace issues, your code should run without this error.

your calling the function before it's been defined

 

<?php
include("GallerySizer.php");
include("config.php");
DEFINE("IMAGE_FULL", '../adam/photos/');

//database connect


$db_server ="this is correct";     
$db_user = "this is correct";    
$db_pass = "this is correct";     
$db_name = "this is correct";
$con = mysql_connect("$db_server","$db_user","$db_pass");
//insert image
function insert_location($thumb_obj) {
  $image_location = $thumb_obj->getImageLocation();
  $thumb_location = $thumb_obj->getThumbLocation();
  // If image matches cover selection, update album cover
  if($cover == $_FILES['image']['name'][$i]){
    $sql = "UPDATE albums SET album_cover = '" . $thumb_location . "' WHERE album_id = " . $_POST['album_id'];
    $result = @mysql_query($sql) or die("Error inserting records: " . mysql_error());
  }
  mysql_select_db("db218351273", $con);
  $sql = ("INSERT INTO photos (photo_id, photo_title, photo_desc, photo_date, photo_location, thumbnail_location,album_id) 
  VALUES('0', '$_POST[photo_title]', '$_POST[photo_desc]', 'NOW()', '$image_location', '$thumb_location', '$_POST[album_id]')");
  $result = mysql_query($sql) or die("Error inserting record(s) into the database: " . mysql_error());
  if ($result){
    echo("Images successfully converted and stored! <br />Click <a href='index.html'>here</a> to continue.");
  }
}
// Album cover
$cover = $_FILES['image']['name'][$_POST['album_cover']];
if (!$_REQUEST['process']){
  echo("Error! No images chosen for processing. <br />");
  echo("Click <a href='index.php'>here</a> to start processing your images.");
  die();
} elseif (!$_POST['album_id']){
  echo("No album selected. Please <a href=\"\">choose an album</a> to upload images to.");
  die();
} else {
    for($i = 0; $i < count($_FILES['image']['tmp_name']); $i++){
    $fileName = $_FILES['image']['name'][$i];
    copy($_FILES['image']['tmp_name'][$i], IMAGE_FULL . $fileName);
    $thumb = new GallerySizer();
    if($thumb->getLocation($_FILES['image']['name'][$i])){
      if($thumb->loadImage()){
        echo("Still here!");
        if($thumb->getSize()){
          if($thumb->setThumbnail()){
            if($thumb->copyThumbImage()){
              if($thumb->resizeImage()){
                $thumb->copyResizedImage();
              }
            }
          }
        }
      }
      else {
        echo("Invalid image/file has been uploaded. Please upload a supported file-type (JPEG/PNG)"); 
        unlink(IMAGE_FULL . $fileName);
        die();
      }
      insert_location($thumb);
    }
  } 
}

?>

 

 

try that also spaced your code up
