Respuesta: subir multiples imagenes y crear thumbnail

Lo primero es saber cuantas imagenes vas a cargar tonces necesitas preguntar eso primero:

Creas una pagina que se llame como tu quieras .html:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">
<html xmlns="">
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Documento sin t&iacute;tulo</title>

<form id="form1" name="form1" method="post" action="Aqui vas a poner la dirección de tu pagina esa que tu tas mostrando">

Ingresa el numero de fotos a cargar:
<input type="text" name="cantidad" />

<input type="submit" name="Submit" value="Enviar" />


Esa pagina te envia la cantidad de fotos a cargar y t dirige hacia esa que tas mostrando alla arriba con tan solo poner el nombre de tu pagina de arriba en el action.

Luego haces estas modificaciones en tu pagina de arriba y ya:

Código PHP:

$idir = $session->username."/images/"; // Path To Images Directory
$tdir = $session->username."/images/thumbs/"; // Path To Thumbnails Directory
$twidth = "125"; // Maximum Width For Thumbnail Images
$theight = "100"; // Maximum Height For Thumbnail Images

if (!isset($_GET['subpage'])) { // Image Upload Form Below
{ ?>

<form method="post" action="uploader.php?subpage=upload" enctype="multipart/form-data">
File:<br />
<input type="file" name="imagefile<? echo $i; ?>" class="form">
<br /><br />
<input name="submit" type="submit" value="Sumbit" class="form"> <input type="reset" value="Clear" class="form">
} else if (isset($_GET['subpage']) && $_GET['subpage'] == 'upload') { // Uploading/Resizing Script
$url = $_FILES['imagefile'.$i.'']['name']; // Set $url To Equal The Filename For Later Use
if ($_FILES['imagefile'.$i.'']['type'] == "image/jpg" || $_FILES['imagefile'.$i.'']['type'] == "image/jpeg" || $_FILES['imagefile'.$i.'']['type'] == "image/pjpeg") {
$file_ext = strrchr($_FILES['imagefile'.$i.'']['name'], '.'); // Get The File Extention In The Format Of , For Instance, .jpg, .gif or .php
$copy = copy($_FILES['imagefile'.$i.'']['tmp_name'], "$idir" . $_FILES['imagefile'.$i.'']['name']); // Move Image From Temporary Location To Permanent Location

if ($copy) { // If The Script Was Able To Copy The Image To It's Permanent Location
print 'Image uploaded successfully.<br /><a href="'.$session->username.'/images/'.$url.'"><img src="'.$session->username.'/images/thumbs/'.$url.'"></a>'; // Was Able To Successfully Upload Image
$simg = imagecreatefromjpeg("$idir" . $url); // 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" . $url); // Saving The Image
imagedestroy($simg); // Destroying The Temporary Image
imagedestroy($dimg); // Destroying The Other Temporary Image
print 'Image thumbnail created successfully.'; // Resize successful
} else {
print '<font color="#FF0000">ERROR: Unable to upload image.</font>'; // Error Message If Upload Failed
} else {
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>';
