How to delete a file from upload folder

 

This tutorial teaches you how to delete a file/files from the specific folder using PHP.

Sometimes while deleting a record from database table, you also need to delete an image/file from the uploaded folder which is   associated to that record. 

For example, if you are removing a product from the table, at the same time, you also need to remove an uploaded product-image. So 

For this,

In PHP, there is a function called unlink().  Using unlink() function you can  remove a file from the specified folder.

Retrieve the product-image from database and pass it to unlink function along with full path.

 

Syn:

 
unlink("path_to_your_upload_directory/".filename_with_extension. );

ex

unlink("uploads/".$product_image );

Example Code

delete_product,php

<?php

$product_id = $_GET['pid']; 

$con  = mysqli_connect('localhost', 'root', '', 'productsdb');  

$SQL1 =  "SELECT FROM products WHERE product_id = $product_id"; 

$result1 = mysqli_query($con, $SQL1) ;

$row =  mysqli_fetch_assoc($result1) ;

$product_image  = $row['product_image'];

$SQL2 =  "DELETE FROM products WHERE product_id = $product_id";
 

$result2 = mysqli_query($con, $SQL2)or die(mysql_error());  

 
if($result2)
{

$product_image = 'uploads/'.$product_image ;

if (file_exists($product_image )) {
   

unlink($product_image );

echo "Product deleted";
 
 } 

}

...
