How To Upload Photo To My Hosting Server Folder Directory

Hello I was trying to upload a photo from a website I made, to the website's hosting server's folder directory (/public_html/upload/) using php. but the folder always shows up empt

Solution 1:

Imporved working Code:

<?php
   $target = "/public_html/upload/"; 
   $target = $target .$_FILES['photo']['name'];
   $pic=($_FILES['photo']['tmp_name']);
   move_uploaded_file($pic, $target);
?> 

Solution 2:

I have updated your code to work.

HTML - is ok but could be formatted better, try a online formatter tool http://jsbeautifier.org/.
Also, form opening tag should look like this

<form action="add_data.php" method="post" enctype="multipart/form-data">

PHP - Explanation provided in the comments

<?php

// Uploaded file will be stored in a temporary location and needs to
// be moved to a destination directory and given the original filename
//-----------------------------------------------------------------

//  prepare target pathname
//
$target = "/public_html/upload";
$targetName = $_FILES['photo']['name'];

// get temp file name
//
$tmp = $_FILES['photo']['tmp_name'];

// use php's move_uploaded_file() function
// to copy temp file to final destination
move_uploaded_file($tmp, $targetDir . $targetName);
