upload file with php and save path to sql

Question

Does anyone know any good tutorial on how to upload a file with php and save the files path to a sql server?

Answer 1

To upload a file you need at least a HTML POST form with multipart/form-data encoding. Therein you put an input type="file" field to browse the file and a submit button to submit the form.

In the upload.php the uploaded file is accesible by $_FILES with the field name as key.

$file = $_FILES['file'];

You can get its name as follows:

$name = $file['name'];

You need to move it to a permanent location using move_uploaded_file(), else it will get lost:

$path = "/uploads/" . basename($name);
if (move_uploaded_file($file['tmp_name'], $path)) {
    // Move succeed.
} else {
    // Move failed. Possible duplicate?
}

You can store the path in database the usual way:

$sql = "INSERT INTO file (path) VALUES ('" . mysqli_real_escape_string($path) . "')";
// ...
