Answer 4

Change these parameters in your php.ini file; (Currently it allow only 2Mb size to upload and post). Sometimes it's reason for these errors.

upload_max_filesize = 500M
post_max_size = 500M
max_execution_time = 120

Warning: getimagesize() [function.getimagesize]: Filename cannot be empty in

Verify the MAX_SIZE variable, example to define it for a 2Mo image:

define('MAX_SIZE', 2000000);
<form enctype="multipart/form-data" method="post" action="upload.php">
<input type="hidden" name="MAX_FILE_SIZE" value="<?php echo MAX_SIZE; ?>" /> 
<input name="fichier" type="file" id="fichier_a_uploader" /> <br>
<input type="submit" name="submit" value="Uploader" /> 
</form>

you can also verify the Maximum size of POST data that PHP will accept and Maximum allowed size for uploaded files in PHP.ini : post_max_size = ? upload_max_filesize = ?

Answer 6

You checked if the form was submitted, but didn't check if the file was sent. In some cases, a form could be submitted but the file will not sent (i.e. file size is bigger then file size limit in config).

Use this:

if(isset($_POST["submit"]) && isset($_FILES['file'])) {
    $file_temp = $_FILES['file']['tmp_name'];   
    $info = getimagesize($file_temp);
} else {
    print "File not sent to server succesfully!";
    exit;
}

You see && isset($_FILES['file']) is new

Or you can extend it

if(isset($_POST["submit"]) && isset($_FILES['file'])) {
    $file_temp = $_FILES['file']['tmp_name'];   
    $info = getimagesize($file_temp);
} 
elseif(isset($_POST["submit"]) && !isset($_FILES['file'])) {
    print "Form was submitted but file wasn't send";
    exit;
}
else {
    print "Form wasn't submitted!";
    exit;
}
