I have an error of Undefined index: file in php

Question

Hi I am having an Undefined index: file error here it says $fileName, $fileTmpName, $fileSize, $fileError, $fleType are the problems.

if(isset($_POST['pic_submit'])) //if UPLOAD is clicked
    {
        $id = $_SESSION['user_id'];
        $fileName= $_FILES['file']['name'];
        $fileTmpName = $_FILES['file']['tmp_name'];
        $fileSize = $_FILES['file']['size'];
        $fileError = $_FILES['file']['error'];
        $fileType = $_FILES['file']['type'];

            var_dump($fileName);
        $fileExt = explode('.', $fileName);
        $target_dir = "/images/";
        $target_file = $target_dir.$fileName;


        $imageFileType = strtolower(pathinfo($target_file, PATHINFO_EXTENSION));

        $allowed = array('jpg', 'jpeg', 'png', 'pdf', 'gif');
        //if (in_array($fileActualExt, $allowed))
        //{

        if(isset($fileName))
        {
            $fileNameNew = uniqid('', true).".".$imageFileType;
            $fileDestination = '../images/'.$fileNameNew;
            move_uploaded_file($fileTmpName, $fileDestination);
        }

}

Just ensure everything is set inside of your main if condition. The isset has an arity of variadic length, so you can ensure that all your conditions are set before you enter your loop.

Just doing:

if(isset($_POST['pic_submit'], $_FILES['file'])) //if UPLOAD is clicked

should cut it.
