    How to perform a file upload in php

    Hi, i am an asp.net developer but recently had to switch to php to design a website for a friend, i am currently trying out the file upload but keep on getting errors.
    error: Undefined index
    I've tried soo many scripts online but none work, so could you please here me out.

    Code:
    <form action="getfile.php" method="post" enctype="multipart/form-data>
    <input type="file" name="uploadedFile" >
    <input type="submit" value="Upload File">
    </form>
    Code:
    <?php
    echo $_FILES['uploadedFile']['name'];
    if( $_FILES['uploadedFile']['name'] != "" )
    {
       copy( $_FILES['uploadedFile']['name'], "uploads/" ) or 
               die( "Could not copy file!");
    }
    else
    {
        die("No file specified!");
    }
    ?>
    i tried this too:
    Code:
    $target_path = "uploads/";
    
    $target_path = $target_path . basename( $_FILES['uploadedfile']['name']); 
    
    if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
        echo "The file ".  basename( $_FILES['uploadedfile']['name']). 
        " has been uploaded";
    } else{
        echo "There was an error uploading the file, please try again!";
    }

    The second script should work, you seem to be missing a capital F on "uploadedFile" though.

    One thing you'll want in order to avoid "undefined index" type error messages is to make sure the $_FILES array element is there before you try to access it, e.g.:
    PHP Code:
    if( ! empty($_FILES['uploadedFile'])) {
        
    // do stuff with $_FILES['uploadedFile']
    }
    else {
        
    // handle error condition of no uploaded file, perhaps including some debug code for now?
