HTML Form File Uploads doesn't upload file

Question

Files doesn't get uploaded though all back-end code is correct. I tested the back end code with another front-end styled code and it worked fine.

but in my front end code it doesn't upload any files. I removed all css and scripts as well to figure out the issue.

here is my simple front end HTML form :

<form action="upload_handler.php" method="post">
    Select image to upload:
    <input type="file" name="fileToUpload" id="fileToUpload">
    <input type="submit" value="Upload" name="submit">
</form>

Answer 1

you forgot to mention the enctype="multipart/form-data"

<form action="upload_handler.php" enctype="multipart/form-data" method="post">
    Select image to upload:
    <input type="file" name="fileToUpload" id="fileToUpload">
    <input type="submit" value="Upload" name="submit">
</form>
