Udah lama ne ga update blog gue... Ne gue dapet dari om google, cara mudah untuk menyimpan gambar.
Oh iya, script ini sudah dilengkapi dengan auto resize gambar dan sudah dilengkapi fungsi cek apakah yang diupload itu gambar atau bukan.
Ini gw ambil dari simpeg online Pemkab Trenggalek. Silahkan diedit sesuai keperluan Anda.
Script untuk menyimpan gambar:

view plain print

3. // DATABASE
4. $db_host = "localhost";
5. $db_user = "root";
6. $db_pass = "p455w0rdku";
7. $db_name = "simpol";
9. // BAGIAN INI KE BAWAH JANGAN DIUBAH
10. $link = mysql_pconnect ($db_host, $db_user, $db_pass) or die ("Ga bisa connect");
11. mysql_select_db ($db_name) or die ("Ga bisa select database");
13. if (isset($act) && $act == "up_foto") {
14. $id = trim($nip);
15. $editFormAction = $_SERVER['PHP_SELF'];
16. $img_thumb_width = 120;
17. $path_thumbs = "items/icons";
19. $file_type = $_FILES['imgfile']['type'];
20. $file_name = $_FILES['imgfile']['name'];
21. $file_size = $_FILES['imgfile']['size'];
22. $file_tmp = $_FILES['imgfile']['tmp_name'];
24. //check if you have selected a file.
25. if(!is_uploaded_file($file_tmp)){
26. echo "
    
    Anda belum memilih file gambar.....";
27. print "refresh" content="0; URL=?mod=up_foto&nip=$nip">";
28. exit(); //exit the script and don't do anything else.
29. }
30. //check file extension jika salah or bukan gambar langsung keluar
31. $size =GetImageSize("$file_tmp");
32. if (($size[2] < 1) || ($size[2] > 4)) {
33. echo '
    
    Maaf yang Anda pilih bukan gambar';
34. print "refresh" content="0; URL=?mod=up_foto&nip=$nip">";
35. exit();
36. }
39. //get the file extension.
40. $getExt = explode ('.', $file_name);
41. $file_ext = $getExt[count($getExt)-1];
43. //create a random file name
45. $rand_name= "tmp";
46. //get the new width variable.
47. $ThumbWidth = $img_thumb_width;
49. //keep image type
50. if($file_size){
51. if($file_type == "image/pjpeg" || $file_type == "image/jpeg"){
52. $new_img = imagecreatefromjpeg($file_tmp);
53. }elseif($file_type == "image/x-png" || $file_type == "image/png"){
54. $new_img = imagecreatefrompng($file_tmp);
55. }elseif($file_type == "image/gif"){
56. $new_img = imagecreatefromgif($file_tmp);
57. }
58. //list width and height and keep height ratio.
59. list($width, $height) = getimagesize($file_tmp);
60. $imgratio=$width/$height;
61. if ($imgratio>1){
62. $newwidth = $ThumbWidth;
63. $newheight = $ThumbWidth/$imgratio;
64. }else{
65. $newheight = $ThumbWidth;
66. $newwidth = $ThumbWidth*$imgratio;
67. }
69. //function for resize image.
70. if (function_exists(imagecreatetruecolor)){
71. $resized_img = imagecreatetruecolor($newwidth,$newheight);
72. }else{
73. die("Error: Please make sure you have GD library ver 2+");
74. }
75. imagecopyresized($resized_img, $new_img, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
76. //save image
77. ImageJpeg ($resized_img,"$path_thumbs/$rand_name.$file_ext");
78. ImageDestroy ($resized_img);
79. ImageDestroy ($new_img);
84. $gb_baru = "$path_thumbs/$rand_name.$file_ext";
86. ///ini ke bawah buat nyimpen gambar ke database
88. $fp = fopen($gb_baru, 'r') or die('ga bisa buka gambar');
91. $data=fread($fp,filesize("$gb_baru"));
92. $data = mysql_escape_string($data);
94. $updatesql=mysql_query("UPDATE foto SET FOTO='$data' where NIP='$id'") or die(mysql_error());
95. }
98. }
99. ?>
100. 
     
101. 
     
102. "100%" border="0" cellpadding="0" cellspacing="1" background="items/bg_gradasi.jpg">

"73%">"items/icons/duk.gif" hspace="5" align="absmiddle" /> EDIT FOTO

"27%" align="center">

108. "POST" enctype="multipart/form-data" action="?mod=up_foto&nip=&act=up_foto">
109. "58%" border="0" align="center">

"176" rowspan="3" align="center" valign="middle">"3" border="0"> "100%" bgcolor="#999999">"0" cellpadding="3" width="100%" border="0"> "#ededed">"?mod=up_foto&nip=">"modul/foto.php?nip=" alt="Foto" name="foto" border="3" id="foto" />	"23" colspan="2" valign="bottom">Silahkan klik "Browse" dan pilih foto yang baru, kemudian klik "Submit".

"310" valign="middle">	"66" align="center" valign="middle">"submit" name="Submit" value="Submit" />

Kalo yang ini untuk menampilkan gambarnya:

view plain print

4. // DATABASE
5. $db_host = "localhost";
6. $db_user = "root";
7. $db_pass = "p455w0rdku";
8. $db_name = "simpol";
10. // BAGIAN INI KE BAWAH JANGAN DIUBAH
11. $link = mysql_pconnect ($db_host, $db_user, $db_pass) or die ("Ga bisa connect");
12. mysql_select_db ($db_name) or die ("Ga bisa select database");
15. require_once ('../inc/db.php');
16. $sql = mysql_query("SELECT NIP,FOTO FROM foto where foto.NIP = "$nip" ") or die(mysql_error());
18. while ($res=mysql_fetch_array($sql)) {
19. echo $res['FOTO'];
20. }
21. mysql_free_result($sql);
23. ?>

Kemudian struktur databasenya sebagai berikut:

view plain print

1. CREATE TABLE `foto` (
2. `NIP` varchar(27) NOT NULL default '',
3. `FOTO` longblob,
4. PRIMARY KEY (`NIP`)
5. ) ENGINE=MyISAM DEFAULT CHARSET=latin1;

Cuman begitu saja. Semoga bermanfaat.
