I have a problem with $ _FILES PHP to upload a photo Indefinite index fileToUpload this is my code

HTML

<form action="upload.php" method="post" enctype="multipart/form-data">
     Seleccionar imagen:
    <input type="file" name="fileToUpload" id="fileToUpload">
    <input type="submit" value="Upload Image" name="submit">
</form>

PHP

//el error aparece en $_FILES["fileToUpload"]["name"]
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;

$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);

if(isset($_POST["submit"])) {

    $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
    if($check !== false) {
        echo "El archivo es una imagen - " . $check["mime"] . ".";
        $uploadOk = 1;
    } else {
        echo "El archivo no es una imagen.";
        $uploadOk = 0;
    }
}

I have tried in different ways but the result is always the same:

Notice: Undefined index: fileToUpload

When you run var_dump($_FILES) it returns me:

array (0) {}

but if I run it this way var_dump($_FILES['foto']['name']) keeps generating the same error.

You can solve it by inserting the lines of code that have to do with the image, inside the If that validates if the button name="submit" has been pressed. In addition to validating if the image was loaded on the server without errors, verifying that the error code other than 4.

$target_dir = "uploads/";

// print_r($_FILES);

if(isset($_POST["submit"])) {

    if($_FILES["fileToUpload"]["error"] != 4) {

        $target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);

        $uploadOk = 1;

        $imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);

        $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
        if($check !== false) {
            echo "El archivo es una imagen - " . $check["mime"] . ".";
            $uploadOk = 1;
        } else {
            echo "El archivo no es una imagen.";
            $uploadOk = 0;
        }

    }

}
