PHP file upload error Undefined index

Question

I have this HTML code:

<form id="uploadForm" action="" method="post"  enctype= "multipart/form-data">
<input type="file" name="fileToUpload" >
<input type="submit" name="submit" value="Submit"><br />

This is the PHP code:

$target_dir = "/";
    $file = $_FILES['fileToUpload']['name'];
    $target_file = $target_dir . $file;
    $uploadOk = 1;
    $imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
    // Check if image file is a actual image or fake image
        $check = getimagesize($_FILES['fileToUpload']['tmp_name']);
        if($check !== false) {
            echo "File is an image - " . $check['mime'] . ".";
            $uploadOk = 1;
        } else {
            echo "File is not an image.";
            $uploadOk = 0;
        }

And I want upload file but I get this notice message:

Notice: Undefined index: fileToUpload

Add a check `if(isset($_POST['submit'])){//do something}` add your Php code inside this condition — devpro, Oct 01 '16 at 11:31
Still not working than u need to chk `print_r($_FILES)` chk the correct file Name or share the result — devpro, Oct 01 '16 at 11:36
if(isset($_POST['submit'])){} put inside your code it will work — Samyappa, Oct 01 '16 at 11:41

<form id="uploadForm" action="" method="post"  enctype= "multipart/form-data">
<input type="file" name="fileToUpload" >
<input type="submit" name="submit" value="Submit"><br />
</form>
<?php
if(isset($_POST["submit"]))
{
    $target_dir = "/";
    $file = $_FILES['fileToUpload']['name'];
    $target_file = $target_dir . $file;
    $uploadOk = 1;
    $imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
    // Check if image file is a actual image or fake image
        $check = getimagesize($_FILES['fileToUpload']['tmp_name']);
        if($check !== false) {
            echo "File is an image - " . $check['mime'] . ".";
            $uploadOk = 1;
        } else {
            echo "File is not an image.";
            $uploadOk = 0;
        }
}

?>

I have same code, unfortunately I didn´t paste form closing tag and this condition. — M. Falex, Oct 01 '16 at 11:44
