Hi,

i am trying to validate my upload form and struggling with a couple of validation methods. i want to not allow the user to upload the file larger than 5mb i have changed my php.ini file to 5M and done some coding to make it work but when i upload a file larger than 5mb i want the screen to echo something like "file too large to upload" but i dont know how to put that in. could someone advise please (code is below)

my other question is how to check before my file is uploaded weather a file in the database has the same name. i am uploading images to a folder and storing the images path in the database please help it would be soo helpful!

PHP Code:

<?php
 
 $max_size=5*1024*1024;
 $filename =.  basename($_FILES['uploaded_file']['name']);
 
 // Check if a file has been uploaded
if(isset($_FILES['uploaded_file']) && $_FILES['uploaded_file']['size']<= $max_size)
{
     // Make sure the file was sent without errors
     if($_FILES['uploaded_file']['error'] == 0) {
         $target_path = "images/";
        $target_path = $target_path . basename( $_FILES['uploaded_file']['name']); 

    if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $target_path)) {
    echo "The file ".  basename( $_FILES['uploaded_file']['name']). 
    " has been uploaded";
    
    $dbLink = new mysqli('localhost', 'root', '', 'gallery');
         if(mysqli_connect_errno()) {
             die("MySQL connection failed: ". mysqli_connect_error());
                                     }             
         
         // Gather all required data
         $name = $dbLink->real_escape_string($_FILES['uploaded_file']['name']);
         $mime = $dbLink->real_escape_string($_FILES['uploaded_file']['type']);
         $size = intval($_FILES['uploaded_file']['size']);
         $image_path = $dbLink->real_escape_string($target_path);
         $gallery_type = $dbLink->real_escape_string($_POST['gallery_type']); 

    //query to insert the data i had gathered into the database
    $query = "INSERT INTO `images` (`name`, `size`, `created`, `image_path`, `gallery_type_id`)
             VALUES ('{$name}', {$size}, NOW(), '{$image_path}', '{$gallery_type}')";
             
             //executes the query
                 $dbLink->query($query);
        } 
    }
      else {
             echo 'Error! A file was not sent!';
            }
}
  
 // Echo a link back to the main page
 echo '<p>Click <a href="member-index.php">here</a> to go back</p>';
 ?>
