Simple File Uploading With PHP

In this tutorial you are going to learn , How to upload files using PHP and moves uploaded files into the specified files folder, Using some PHP global variable like $_FILES[‘controller_name’] , move_uploaded_files() , you can move uploaded file into the folder it’s easy, for that we have to create html form and embed few lines of PHP code into the single file, let’s have a look.

Download Script

Configure The “php.ini” File

open your php.ini file and search for following keys and make some changes as i change like below :
1 . file_uploads = On
2 . upload_max_filesize = 50M
upload_max_filesize helps you to maximize file uploading size, by default it is 2, you can maximize as your need.

The html form :


<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>File Uploading With PHP and MySql</title>
</head>
<body>
<form action="" method="post" enctype="multipart/form-data">
<input type="file" name="pic" />
<button type="submit" name="btn-upload">upload</button>
</form>
</body>
</html>

Make Sure :
1 . Method=”POST” : it should be POST.
2 . enctype=”multipart/form-data” : it’s specify content-type to be uploaded.
3 . type=”file” : attribute of the input tag shows input field as a file selector with a “Browse” Button.

The PHP

We will use isset($_FILES[‘name_of_input’]) to make sure some file is selected.
here in this following script javascript was just used for message that file was upload or not.
put this script just above <!DOCTYPE html> tag


<?php
if(isset($_POST['btn-upload']))
{
        $pic = rand(1000,100000)."-".$_FILES['pic']['name'];
        $pic_loc = $_FILES['pic']['tmp_name'];
        $folder="uploaded_files/";
        if(move_uploaded_file($pic_loc,$folder.$pic))
        {
            ?><script>alert('successfully uploaded');</script><?php
        }
        else
        {
            ?><script>alert('error while uploading file');</script><?php
} 
}
?>

PHP Script explained :
1 . $folder : Directory where files are uploaded.
2 . move_uploaded_files : php function that moves selected file to the specified folder.
3 . rand() : this is the awesome function that enables you to upload same files multiple times.

Complete Script

index.php


<?php
if(isset($_POST['btn-upload']))
{
     $pic = rand(1000,100000)."-".$_FILES['pic']['name'];
    $pic_loc = $_FILES['pic']['tmp_name'];
     $folder="uploaded_files/";
     if(move_uploaded_file($pic_loc,$folder.$pic))
     {
        ?><script>alert('successfully uploaded');</script><?php
     }
     else
     {
        ?><script>alert('error while uploading file');</script><?php
     }
}

?>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>File Uploading With PHP and MySql</title>
</head>

<form action="" method="post" enctype="multipart/form-data">
<input type="file" name="pic" />
