[SOLVED] Confused with error message - Call to undefined method

adam291086 · September 25, 2007

Some one was helping me on this and i am confuse and hes gone offline. I can the following error;

Fatal error: Call to undefined method: gallerysizer->getlocation() in /homepages/12/d214897219/htdocs/adam/create_thumbnails.php on line 21

I get what it means but wheres the problem in my code?


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


// 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->copyImage()){
if($thumb->resizeImage()){
$thumb->copyResize();
$thumb->display(); 
}
}
}
}
} else {
echo("Invalid image/file has been uploaded. Please upload a supported file-type (JPEG/PNG)"); 
unlink(IMAGE_FULL . $fileName);
die();
}
insert_location($thumb);
} else {
echo("Error processing images: " . mysql_error());
}
// If image matches cover selection, update album cover
if($cover == $_FILES['image']['name'][$i]){
$sql = "UPDATE albums SET album_cover = '" . $thumb->getThumbLocation() . "' WHERE album_id = " . $_POST['album_id'];
$result = @mysql_query($sql) or die("Error inserting records: " . mysql_error());
} 
}
}
function insert_location($thumb_obj){
$image_location = $thumb_obj->getImageLocation();
$thumb_location = $thumb_obj->getThumbLocation();
$dbcnx = mysql_connect("localhost", "root", "");
mysql_select_db("album", $dbcnx);
$sql = "INSERT INTO photos values(0, '$_POST[photo_title]', '$_POST[photo_desc]', NOW(), '$image_location', '$thumb_location', $_POST[album_id])";
$result = mysql_query($sql, $dbcnx) or die("Error inserting record(s) into the database: " . mysql_error());

I already told you!

PHP is case-sensitiv.

call it like

gallerysizer->getLocation();

with an upper L

yeah i have done that, but still getting the same error. i have post another thread showing the two different code files. Sorry to be a pain

Ah I see... the function getLocation is not in a class

You closed the class...

<?php
class GallerySizer{
      var $img;     // Original image file object
      var $thumb;          // Thumbnail file object
      var $resize;         // Resized image file name
      var $width;          // Original image width
      var $height;         // Original image height
      var $new_width;      // Resized image width
      var $new_height;     // Resized image height
      var $image_path;     // Path to image
      var $thumbscale;     // Scale to resize thumbnail
      var $image_file;     // Resized image filename
      var $thumbnail;      // Thumbnail image file object
      var $random_file;    // Resized image file name (random)
} // you closed it here... move this sign down

   /*****
     * Retrieves path to uploaded image.
     * Retrieves filename of uploaded image
     */
    function getLocation($image){
        $this->image_file = str_replace("..", "/", $image);
        $this->image_path = IMAGE_BASE . $this->image_file;
        return true;
    }
//...
?>

But better is to learn PHP

thanks. I have no solved the next few errors but stumped at this one

Parse error: parse error, unexpected $ in /homepages/12/d214897219/htdocs/adam/gallerysizer.php on line 199

This is because there is no $ on line 199
