File Upload in PHP


$_FILES is a superglobal variable in PHP. It consists of 5 variable:

·         $_FILES[‘file’][‘tmp_name’] – the uploaded file in the temporary directory on the web server.

·         $_FILES[‘file’][‘name’] – the name of the file which is uploaded.

·         $_FILES[‘file’][‘size’]-the size of the uploaded file.

·         $_FILES[‘file’][‘type’]-the MIME type of the uploaded file.

·         $_FILES[‘file’][‘error’]-the error will be shown.

                                                                                        

Step 1: Create a form. While creating a form some rules must be follow:

·         The form must uses a method=”post”.

·         The form also need the attribute: enctype =”multipart/form-data”. It specifies which content is to be used while submitting the form.

·         NOTE: In <input> tag “file” must be given.

 

<html>

   <body>

     

      <form action=”image.php” method="POST" enctype="multipart/form-data">

         <input type="file" name="image" />

         <input type="submit" name="submit"/>

      </form>

     

   </body>

</html>

 

Step 2: Create image.php

<?php

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

{

move_uploaded_file($_FILES["image"]["tmp_name"],"../user/".$_FILES["image"]["name"]);

?> // upload the file in user folder.

 <img src="<?php echo $_FILES["image"]["name"];?>" width="300px" height="200px">//preview your image

<?php

}

?>
