jQuery.Formアップロードファイル操作


testフォルダを作成
PHPコード:

<?php
//var_dump($_FILES['file']);exit;
if(isset($_GET['option']) && $_GET['option']=='delete'){
 @file_put_contents(dirname(__FILE__)."/------------0.txt", $_GET['path']."\r
",FILE_APPEND); unlink($_GET['path']); $rs[] = array( 'success'=>true, 'info'=>'ok' ); if(file_exists($_GET['path'])){ $rs[]['success']=false; $rs[]['info']=' '; } die(json_encode($rs)); } if ((($_FILES["file"]["type"] == "image/gif") || ($_FILES["file"]["type"] == "image/jpeg") || ($_FILES["file"]["type"] == "image/png") || ($_FILES["file"]["type"] == "image/pjpeg")) && ($_FILES["file"]["size"] < (1024*1024))) { if ($_FILES["file"]["error"] > 0) { echo "Return Code: " . $_FILES["file"]["error"] . "<br />"; } else { if (file_exists("test/" . $_FILES["file"]["name"])) { $fn = $_FILES["file"]["name"]; } else { $imgurl = substr($_FILES["file"]["name"], strpos($_FILES["file"]["name"], '.')); $imgurl = date("YmdHis",time()).$imgurl; move_uploaded_file($_FILES["file"]["tmp_name"],"test/" . $imgurl); $fn = "test/" . $imgurl; } } $return_str[] = array( 'guid'=>date('His',time()), 'path'=>'test/', 'fileName'=>$fn, 'success'=>true ); } else { $return_str[] = array( 'guid'=>date('His',time()), 'path'=>'test/', 'fileName'=>$_FILES["file"]["name"], 'success'=>false, 'error'=>$_FILES["file"]["error"] ); } echo json_encode($return_str); ?>
