Upload & Resize Gambar di PHP

Hallo sobat blogger, kali ini saya mau share nih gmana caranya upload gambar di php. Tidak lama-lama, langsung saja kita tembak ke sasaran....

Ini struktur tabel nya....

CREATE TABLE IF NOT EXISTS `data_gambar` (
`id_gambar` int(11) NOT NULL AUTO_INCREMENT,
`gambar` varchar(100) NOT NULL,
`gambar_kecil` varchar(100) NOT NULL,
`tanggal_upload` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
PRIMARY KEY (`id_gambar`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;

Setelah kita selesai membuat tabel di database, kemudian kita membuat file phpnya...

ini file koneksinya..... (koneksi.php)

<?php

$host = "localhost";
$user = "root";
$password = "elektro";
$database = "member";
$con = mysql_connect($host,$user,$password)or die(mysql_error());
if($con == TRUE)
mysql_select_db($database)or die(mysql_error());
?>

setelah file koneksinya, kita buat file utamanya..... (upload_gambar.php)

<?php
include 'koneksi.php';

$idir = "foto/"; // Path To Images Directory
$tdir = "foto/tumb/"; // Path To Thumbnails Directory
$twidth = "250"; // Maximum Width For Thumbnail Images
$theight = "250"; // Maximum Height For Thumbnail Images

$url = $_FILES['imagefile']['name']; // Set $url To Equal The Filename For Later Use
if ($_FILES['imagefile']['type'] == "image/jpg" || $_FILES['imagefile']['type'] == "image/jpeg" || $_FILES['imagefile']['type'] == "image/pjpeg" ) {
$file_ext = strrchr($_FILES['imagefile']['name'], '.'); // Get The File Extention In The Format Of , For Instance, .jpg, .gif or .php

$sameName = 1; // Menyimpan banyaknya file dengan nama yang sama dengan file yg diupload
$handle = opendir($idir);
while(false !== ($file = readdir($handle))){ // Looping isi file pada directory tujuan
// Apabila ada file dengan awalan yg sama dengan nama file di uplaod
if(strpos($file,$_FILES['imagefile']['name']) !== false)
$sameName++; // Tambah data file yang sama
}
/* Apabila tidak ada file yang sama ($sameName masih ‘0') maka nama file pakai
* nama ketika diupload, jika $sameName > 0 maka pakai format “namafile($sameName).ext */

$newName = empty($sameName) ? $url : $url.'('.$sameName.')'.$file_ext;

$copy = copy($_FILES['imagefile']['tmp_name'], "$idir" . "$newName"); // Move Image From Temporary Location To Permanent Location

if ($copy) { // If The Script Was Able To Copy The Image To It's Permanent Location
print 'Image uploaded successfully.<br />'; // Was Able To Successfully Upload Image
$simg = imagecreatefromjpeg("$idir" . "$newName"); // Make A New Temporary Image To Create The Thumbanil From
$currwidth = imagesx($simg); // Current Image Width
$currheight = imagesy($simg); // Current Image Height
if ($currheight > $currwidth) { // If Height Is Greater Than Width
$zoom = $twidth / $currheight; // Length Ratio For Width
$newheight = $theight; // Height Is Equal To Max Height
$newwidth = $currwidth * $zoom; // Creates The New Width
} else { // Otherwise, Assume Width Is Greater Than Height (Will Produce Same Result If Width Is Equal To Height)
$zoom = $twidth / $currwidth; // Length Ratio For Height
$newwidth = $twidth; // Width Is Equal To Max Width
$newheight = $currheight * $zoom; // Creates The New Height
}
$dimg = imagecreate($newwidth, $newheight); // Make New Image For Thumbnail
imagetruecolortopalette($simg, false, 256); // Create New Color Pallete
$palsize = ImageColorsTotal($simg);
for ($i = 0; $i < $palsize; $i++) { // Counting Colors In The Image
$colors = ImageColorsForIndex($simg, $i); // Number Of Colors Used
ImageColorAllocate($dimg, $colors['red'], $colors['green'], $colors['blue']); // Tell The Server What Colors This Image Will Use
}
imagecopyresized($dimg, $simg, 0, 0, 0, 0, $newwidth, $newheight, $currwidth, $currheight); // Copy Resized Image To The New Image (So We Can Save It)
imagejpeg($dimg, "$tdir" . "$newName"); // Saving The Image
imagedestroy($simg); // Destroying The Temporary Image
imagedestroy($dimg); // Destroying The Other Temporary Image
print 'Image thumbnail created successfully.'; // Resize successful

$nama_gambarasli = "$tdir"."$newName";
$nama_gambarkukecil = "$idir"."$newName";

//proses simpan
$sql="insert into data_gambar(gambar,gambar_kecil) values('$nama_gambarasli','$nama_gambarkecil')";
$query=mysql_query($sql) or die (mysql_error());
if($query){
echo "Data Berhasil disimpan.";
}

} else {
print '<font color="#FF0000">ERROR: Unable to upload image.</font>'; // Error Message If Upload Failed
} else {
?>
<script>
alert('ERROR: Wrong filetype (has to be a .jpg or .jpeg)');
</script>
<?php
print '<font color="#FF0000">ERROR: Wrong filetype (has to be a .jpg or .jpeg. Yours is '; // Error Message If Filetype Is Wrong
print $file_ext; // Show The Invalid File's Extention
print '.</font>';
}

?>

Wah cukup jelas kan sobat bloger, tinggal langsung simpan semua file tersebut dalam satu direktori / folder dan akses melalui web server lokal....
Nantikan sharing kita selanjutnya ya....jangan lupa tinggalkan komentar ya...
