Be Carefull While Uploading A file To Server Using PHP

With PHP, it is easy to upload files to the server.

However, with ease comes danger, so always be careful when allowing file uploads.


1. Configure The "php.ini" File:

First, ensure that PHP is configured to allow file uploads.

In your "php.ini" file, search for the file_uploads directive, and set it to On:

file_uploads = On

2. Create The HTML Form:

Next, create an HTML form that allow users to choose the image file they want to upload:

<!DOCTYPE html>
<html>
<body>

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

</body>
</html>
 

Some rules to follow for the HTML form above:

  • Make sure that the form uses method="post"
  • The form also needs the following attribute: enctype="multipart/form-data". It specifies which content-type to use when submitting the form

Without the requirements above, the file upload will not work.

Other things to notice:

  • The type="file" attribute of the tag shows the input field as a file-select control, with a "Browse" button next to the input control

The form above sends data to a file called "upload.php", which we will create next.

3. Create The Upload File PHP Script:

The "upload.php" file contains the code for uploading a file:

PHP script explained:

  • $target_dir = "uploads/" - specifies the directory where the file is going to be placed.
  • $target_file specifies the path of the file to be uploaded.
  • $uploadOk=1 is not used yet (will be used later).
  • $imageFileType holds the file extension of the file.
  • Next, check if the image file is an actual image or a fake image.
