Bueno ya encontre una aplicacion que me sirvio muchisimo la posteo para la ayuda de quien lo necesite:
index.php
Código PHP:
<html>
<head>
<script type="text/javascript" src="uploader.js" ></script>
</head>
<body>
<?php
/*require ajax class call*/
require_once("AjaxFileUploader.inc.php");
/*new ajax file uploeader object*/
$ajaxFileUploader = new AjaxFileuploader($uploadDirectory="");
/*upload ajax form elements with diferent id's*/
echo $ajaxFileUploader->showFileUploader('id1');
?>
</body>
</html>
imageupload.php
Código PHP:
<?php
/*dirName main folder file*/
$dirName="uploads";
/*verify id existence*/
if (isset($_POST['id'])) {
//$uploadFile=$_GET['dirname']."/".$_FILES[$_POST['id']]['name'];
@mkdir($dirName,0777);
/*encrypt main name for security measures*/
$uploadFile="$dirName/".md5($_FILES[$_POST['id']]['name']).".jpg";
/*verify directory existence*/
if(!is_dir($_GET['dirname'])) {
echo '<script> alert("No se pudo encontrar la direccion de archivo de subida: $dirName);</script>';
}
/*verify uploaded file*/
if (!copy($_FILES[$_POST['id']]['tmp_name'], $dirName.'/'.md5($_FILES[$_POST['id']]['name']).".jpg")) {
echo '<script> alert("El archivo no pudo subirse");</script>';
}
}
else {
/*full path*/
$uploadFile="$dirName/".md5($_GET['filename']).".jpg";
if (file_exists($uploadFile)) {
/*link image to open image and delete*/
echo "Imagen Subida <a href='$uploadFile'>Open File</a> <a href='deletefile.php?filename=".$uploadFile."'>Delete File</a>";
/*image preview*/
echo "<br><img src='".$uploadFile."' alt='".$uploadFile."' />";
}
else {
/*preload animated gif*/
echo "<img src='loading.gif' alt='loading...' />";
}
}
?>
deletefile.php
Código PHP:
<?php
/*delete specific image*/
$homepage="index.php";
if (isset($_GET['filename'])) {
if (unlink($_GET['filename'])) {
header("Location: $homepage");
}
else {
echo "<script type='text/javascript'> alert('Failed to delete: ".$_GET['filename'].". Please try again.');</script>";
}
}
else {
echo "File deleted";
}
?>
AjaxFileUploader.inc.php
Código PHP:
<?php
@session_start();
class AjaxFileuploader {
// PHP 4.x users replace "PRIVATE" from the following lines with "var". Also remove all the PUBLIC, PRIVATE and PROTECTED Kaywords from the class
private $uploadDirectory='';
private $uploaderIdArray=array();
/**
* Constructor Function
*/
public function AjaxFileuploader($uploadDirectory) {
if (trim($uploadDirectory) != '' && is_dir($uploadDirectory)) {
$this->uploadDirectory=trim($uploadDirectory);
}
}
/**
* This function return all the files in the upload directory, sorted according to their file types
*/
public function getAllUploadedFiles() {
$returnArray = array();
$allFiles = $this->scanUploadedDirectory();
return $returnArray;
}
/**
* This function scans uploaded directory and returns all the files in it
*/
private function scanUploadedDirectory() {
$returnArray = array();
if ($handle = opendir($this->uploadDirectory)) {
while (false !== ($file = readdir($handle))) {
if (is_file($this->uploadDirectory."/".$file)) {
$returnArray[] = $file;
}
}
closedir($handle);
}
else {
die("<b>ERROR: </b> Could not read directory: ". $this->uploadDirectory);
}
return $returnArray;
}
/**
* This function returns html code for uploading a file
*/
public function showFileUploader($uploaderId) {
if (in_array($uploaderId, $this->uploaderIdArray)) {
die($uploaderId." already used. please choose another id.");
return '';
}
else {
$this->uploaderIdArray[] = $uploaderId;
return '<form id="formName'.$uploaderId.'" method="post" enctype="multipart/form-data" action="imageupload.php?dirname='.$this->uploadDirectory.'" target="iframe'.$uploaderId.'">
<input type="hidden" name="id" value="'.$uploaderId.'" />
<span id="uploader'.$uploaderId.'" style="font-family:verdana;font-size:10;">
Imagen: <input name="'.$uploaderId.'" type="file" value="'.$uploaderId.'" onchange=\'return uploadFile(this,"'.$this->uploadDirectory.'")\' /></span>
<span id="loading'.$uploaderId.'"></span>
<iframe name="iframe'.$uploaderId.'" src="imageupload.php" width="400" height="100" style="display:none"> </iframe>
</form>';
}
}
}
?>
Importante: necesitan crear un directorio "uploads" que tenga todos los permisos necesarios para poder emplearlo
Saludos a todos y gracias ;)
