    adding error handling and image type

    I been working on this image script for too long now, and I still can't seem to get two things to work - the image type and error handling (if the fields are empty). I have the code for this, but every place I try to add it, it doesn't work.

    my code:

    PHP Code:
    $error_message="";
    $MaxSize "600000";
    if (isset(
    $_POST['btn_update'])){
    function 
    createRandomPassword() {
    $chars "abcde!@#%^fghijkmnoABCDEFGHIJKpqrstuvwxyz023456789ABCDEFGHIJKLMNOPQRSTUVWZ!@#%^&";
    srand((double)microtime()*10000000);
    $i 0;
    $pass '' ;
    while (
    $i <= 19) {
    $num rand() % 60;
    $tmp substr($chars$num1);
    $pass $pass $tmp;
    $i++;
    }
    return 
    $pass;
    }
    if (
    $_FILES['aMyUploads0']['size'] > $MaxSize || $_FILES['aMyUploads1']['size'] > $MaxSize || $_FILES['aMyUploads2']['size'] > $MaxSize)
    {
    $error_message "ERROR: File too big!";

    }
    $aMyUploads = array();
    $password createRandomPassword();
    foreach(
    $_FILES as $aFile)
    {
    $newLocation 'uploads/'.$password .$aFile["name"];
    if(
    === $aFile['error'] && (false !== move_uploaded_file($aFile['tmp_name'], $newLocation)))
    {
    $aMyUploads[] = $newLocation;
    }
    else
    {
    $aMyUploads[] = '';
    }
    }
    $error_message="Journal successfully saved.";
    $connection mysql_connect("localhost""????""???");
    mysql_select_db("????"$connection);
    $insert "INSERT INTO photos (image1, image2, image3) VALUES
    (
    ' "
    .$aMyUploads[0]." ',
    ' "
    .$aMyUploads[1]." ',
    ' "
    .$aMyUploads[2]." '
    )"
    ;
    $add_member mysql_query($insert) or die(mysql_error());


    code im trying to add with no luck:
    PHP Code:
    //ERROR HANDLING CODE:

        
    if(empty($aMyUploads[0]) || empty($aMyUploads[1]) || empty($aMyUploads[2]))
        {
        
    $error_message="Please fill in all fields.";
        }
        else
        {
        
    $error_message="Journal successfully saved.";

    //IMAGE TYPE CODE:

    $allowed_filetypes = array(".jpg"".gif"".jpeg"".png");

    $ext substr($newLocationstrpos($newLocation,'.'), strlen($newLocation)-1);
    if(!
    in_array($ext,$allowed_filetypes))
    {
    $error_message="The file you attempted to upload is not allowed.";

    Try checking to see if there's a $_FILES array first.

    PHP Code:
    if ((!empty($_FILES['aMyUploads0']) && ($_FILES['aMyUploads0']['error'] == 4))) {
        if (
    $_FILES['aMyUploads0']['size'] > $MaxSize || $_FILES['aMyUploads1']['size'] > $MaxSize || $_FILES['aMyUploads2']['size'] > $MaxSize)  { 
            
    $error_message 'ERROR: File too big!'
        }
    } else {
        
    $error_message 'No file selected for upload';

    ...checks to see if $_FILES has something in it and also checks the error code.
