  1 | # PHP nudity and porn image detector
  2 | 
  3 | PHP code by Bakr Alsharif from Egypt:
  4 | http://www.9lessons.info/2014/01/block-uploads-of-adult-or-nude-images.html
  5 | 
  6 | Live demo:

  8 | 
  9 | ## Block Uploads of Adult or Nude Images using PHP.
 10 | 
 11 | I found an interesting and useful class file in phpclasses.org, that helps to detect image nudity based on skin pixel score developed by Bakr Alsharif from Egypt. I had integrated this with my previous tutorial Ajax image upload with Jquery and PHP, sure this code helps you to block adult or nudity images.
 12 | 
 13 | ### Sample database design for Users.
 14 | 
 15 | **Users**
 16 | Contains user details username, password and email etc.
 17 | ```sql
 18 | CREATE TABLE `users` (
 19 | `uid` int(11) AUTO_INCREMENT PRIMARY KEY,
 20 | `username` varchar(255) UNIQUE KEY,
 21 | `password` varchar(100),
 22 | `email` varchar(255) UNIQUE KEY
 23 | )
 24 | ```
 25 | Sample values:
 26 | ```sql
 27 | INSERT INTO `users` 
 28 | (`uid`, `username`, `password`, `email`) 
 29 | VALUES 
 30 | ('1', '9lessons', MD5('password'), 'srinivas@9lessons.info');
 31 | ```
 32 | 
 33 | ### Javascript Code
 34 | 
 35 | `$("#photoimg").on('change',function(){})`
 36 | - photoimg is the ID name of INPUT FILE tag and
 37 | 
 38 | `$('#imageform').ajaxForm()`
 39 | - imageform is the ID name of FORM.
 40 | 
 41 | While changing INPUT it calls FORM submit without refreshing page using `ajaxForm()` method. Uploaded images will `prepend` inside `#preview` tag.
 42 | 
 43 | ```html
 44 | <script type="text/javascript" src="http://ajax.googleapis.com/
 45 | ajax/libs/jquery/2.1.1/jquery.min.js"></script>
 46 | <script type="text/javascript" src="jquery.wallform.js"></script>
 47 | <script type="text/javascript">
 48 | $(document).ready(function() 
 49 | { 
 50 | 
 51 | $('#photoimg').on('change', function() 
 52 |  {
 53 | var A=$("#imageloadstatus");
 54 | var B=$("#imageloadbutton");
 55 | 
 56 | $("#imageform").ajaxForm({target: '#preview', 
 57 | beforeSubmit:function(){
 58 | A.show();
 59 | B.hide();
 60 | }, 
 61 | success:function(){
 62 | A.hide();
 63 | B.show();
 64 | }, 
 65 | error:function(){
 66 | A.hide();
 67 | B.show();
 68 | } }).submit();
 69 | });
 70 | 
 71 | }); 
 72 | </script>
 73 | ```
 74 | 
 75 | Here hiding and showing `#imageloadstatus` and `#imageloadbutton` based on form upload submit status. 
 76 | 
 77 | ### PHP Code
 78 | 
 79 | **index.php**
 80 | Contains simple PHP and HTML code. Here `$session_id=1` means user id session value. 
 81 | ```php
 82 | <?php
 83 | include('db.php');
 84 | session_start();
 85 | $session_id='1'; // User login session value
 86 | ?>
 87 | <div id='preview'>
 88 | </div>
 89 | <form id="imageform" method="post" enctype="multipart/form-data" action='ajaximage.php'>
 90 | Upload image: 
 91 | <div id='imageloadstatus' style='display:none'><img src="loader.gif" alt="Uploading...."/></div>
 92 | <div id='imageloadbutton'>
 93 | <input type="file" name="photoimg" id="photoimg" />
 94 | 
 95 | </div>
 96 | </form>
 97 | ```
 98 | 
 99 | **ajaximage.php**
100 | Contains PHP code. This script helps you to upload images into `uploads` folder. Image file name rename into `timestamp+session_id.extention`
101 | ```php
102 | <?php
103 | include('db.php');
104 | session_start();
105 | $session_id='1'; // User session id
106 | $path = "uploads/";
107 | 
108 | function getExtension($str)
109 | {
110 | $i = strrpos($str,".");
111 | if (!$i)
112 | {
113 | return "";
114 | }
115 | $l = strlen($str) - $i;
116 | $ext = substr($str,$i+1,$l);
117 | return $ext;
118 | }
119 | 
120 | $valid_formats = array("jpg", "png", "gif", "bmp","jpeg","PNG","JPG","JPEG","GIF","BMP");
121 | if(isset($_POST) and $_SERVER['REQUEST_METHOD'] == "POST")
122 | {
123 | $name = $_FILES['photoimg']['name'];
124 | $size = $_FILES['photoimg']['size'];
125 | if(strlen($name))
126 | {
127 | $ext = getExtension($name);
128 | if(in_array($ext,$valid_formats))
129 | {
130 | if($size<(1024*1024)) // Image size max 1 MB
131 | {
132 | //---Image Filter Code
133 | require_once('class.ImageFilter.php');
134 | $filter = new ImageFilter;
135 | $score = $filter->GetScore($_FILES['photoimg']['tmp_name']);
136 | if(isset($score))
137 | {
138 | if($score >= 60) // Score value If more than 60%, it consider as adult image. 
139 | {
140 | echo "Image scored ".$score."%, It seems that you have uploaded a nude picture :-(";
141 | }
142 | else
143 | {
144 | //---Image Filter Code 
145 | $actual_image_name = time().$session_id.".".$ext;
146 | $tmp = $_FILES['photoimg']['tmp_name'];
147 | if(move_uploaded_file($tmp, $path.$actual_image_name))
148 | {
149 | mysqli_query($connection,"UPDATE users SET profile_image='$actual_image_name' WHERE uid='$session_id'");
150 | echo "<img src='uploads/".$actual_image_name."' class='preview'>";
151 | }
152 | else
153 | echo "failed";
154 | //---Image Filter Code 
155 | }
156 | }
157 | //---Image Filter Code 
158 | }
159 | else
160 | echo "Image file size max 1 MB"; 
161 | }
162 | else
163 | echo "Invalid file format.."; 
164 | }
165 | else
166 | echo "Please select image..!";
167 | exit;
168 | }
169 | ?>
170 | ```
171 | 
172 | **db.php**
173 | Database configuration file, just modify database credentials.
174 | ```php
175 | <?php
176 | error_reporting(0);
177 | define('DB_SERVER', 'localhost');
178 | define('DB_USERNAME', 'username');
179 | define('DB_PASSWORD', 'password');
180 | define('DB_DATABASE', 'database');
181 | $connection = @mysqli_connect(DB_SERVER,DB_USERNAME,DB_PASSWORD,DB_DATABASE);

 14 | 	Usage Note:
 15 | 	-----------
 16 | 	Do not use both ajaxSubmit and ajaxForm on the same form.  These
 17 | 	functions are intended to be exclusive.  Use ajaxSubmit if you want
 18 | 	to bind your own submit handler to the form.  For example,
 19 | 
 20 | 	$(document).ready(function() {
 21 | 		$('#myForm').bind('submit', function(e) {
 22 | 			e.preventDefault(); // <-- important
 23 | 			$(this).ajaxSubmit({
 24 | 				target: '#output'
 25 | 			});
 26 | 		});
 27 | 	});
 28 | 
 29 | 	Use ajaxForm when you want the plugin to manage all the event binding
 30 | 	for you.  For example,
 31 | 
 32 | 	$(document).ready(function() {
 33 | 		$('#myForm').ajaxForm({
 34 | 			target: '#output'
 35 | 		});
 36 | 	});
 37 | 
 38 | 	When using ajaxForm, the ajaxSubmit function will be invoked for you
 39 | 	at the appropriate time.
