Now this one is a bit of a shit head. I am using a really comprehensive class i found on on the web for upload / re-size / crop but i want to be able to override it's error handling and i am not good enough to start modifying the code in the class with out fucking it up.

Firstly i will show you how i have invoked the class.
Code: [Select]
if( isset($_FILES['image'] ) ) {

//Class includes
include("../scrips/php/cms/database.insert.class.php");
include ("../scrips/php/cms/img.upload.resize.crop.class.php.php");


//----------|Start: upload, resize & save
$your_image = new _image;

//----------| Upload orginal image
$your_image->uploadTo = 'uploads/';
$upload = $your_image->upload($_FILES['image']);


//----------| Resize and upload small thumbnail
$your_image->newPath = 'thums/';
$your_image->newWidth = 50;
$your_image->newHeight = 50;
$resized = $your_image->resize();



//----------| Resize and upload medium thumbnail
$your_image->newPath = 'thums2/';
$your_image->newWidth = 100;
$your_image->newHeight = 100;
$resized = $your_image->resize();
//----------| Getting the image name to insert into the database futher on in the code
$name = $resized;
$img_str = explode("/",$name);
$final_img_name = $img_str['1'];

echo "Article has been added!";

//----------------|end

//----------------| Start database insert (class manipulation)
$table = "blog_posts";
$title = "'".$_POST['ArticleTitle']."',";
$img = "'".$final_img_name."',";
$post = "'".$_POST['ArticleBody']."',";
$aurthor_id = "'1',";
$category_id = "'".$_POST['Category']."',";
$date_posted = "NOW()";


$values = array("$title","$img","$post","$aurthor_id","$category_id","$date_posted");
$fields = array('title,','img,','post,','aurthor_id,','category_id,','date_posted');
$obj= new DatabaseInsert;
$obj->DatabaseConnectionRequire();
$obj->ArticleInsert($values,$fields,$table);
//----------------|end
}


As you can see it's fairly basic. What i want to do is before it runs this script and starts including/invoking the class etc, i want to be able to check to see if there is a value been posted from a FILE FORM OBJECT and if there is to proceed with this script, alternatively i want it to execute another code which will handle it in regards to the concept of my page. A simple javascript alert with be ok providing it reloaded the page to it's default state. If any one can help me here i would appreciate it a lot. Thanks
