最近因?qū)懸粋€上傳功能,不能刷新頁面,且頁面得有后臺返回的信息,因而不能使用form直接提交表單,嘗試使用is提交并接受返回數(shù)據(jù),不多說代碼如下: 前臺: <form id='pdf-form' enctype="multipart/form-data" method="POST" action="" > <input type="hidden" name="order_id" value="<{$order.order_id}>"> <table align="center" width="90%" border="0"> <tr> <td><b>合同信息:</b> <a target="_self" href="<{link app=b2c ctl=site_paycenter act=download arg0=$contract_no}>" class="active">下載</a></td> <{if $sign ==1}> <td> <input type="file" name="inputpdf" id="inputpdf"> <{button id="button" onclick="upload(this);" class="btn-import" label="合同上傳"}> <span id="span" class="success notice-inline">上傳成功!</span> </td> <{/if}> </tr> </table> </form> js: function upload(o){ var data = new FormData(document.getElementById('pdf-form')); data.append('CustomFile','this is data'); var PDF = new XMLHttpRequest(); PDF.open("post",'<{link app=b2c ctl=site_paycenter act=uploadFile}>',true); PDF.onload = function(){ if(PDF.status == 200){ re =JSON.decode(PDF.responseText); console.log(re); if( re.rsp == 'succ'){ document.getElementById('button').style.display= 'none'; document.getElementById("span").innerHTML=re.res; document.getElementById('span').style.display= ''; // document.getElementById("url").href='.'+re.url; }else{ document.getElementById("span").innerHTML=re.res; document.getElementById('span').style.display= ''; } } }; PDF.send(data); } 后臺處理以及返回信息: function uploadFile() { $file = $_FILES['inputpdf']['name']; $filetempname = $_FILES['inputpdf']['tmp_name']; $filelist = explode('.',$file); $type = end($filelist); if($type != 'pdf'){ $return = array ( 'rsp' => 'fail', 'res' => '請上傳pdf文件!', ); echo json_encode($return);exit; } //自己設(shè)置的上傳文件存放路徑 $filePath = './public/pdf/'; $contract_name = $file; $string_md5 = md5 (md5($contract_name).time()); $front_string = substr ($string_md5 ,0 ,31 ); $contract_url = 's'.$front_string.'.pdf'; //pdf名稱 $uploadfile = $filePath .$contract_url;//上傳后的文件名地址 //move_uploaded_file() 函數(shù)將上傳的文件移動到新位置。若成功,則返回 true,否則返回 false。 $result = move_uploaded_file($filetempname, $uploadfile);//假如上傳到當(dāng)前目錄下 if($result == true){ $orders = app::get('b2c')->model('orders')->getList('contract_no', array('order_id'=>$_POST['order_id'])); //獲取用戶發(fā)票信息 $contracts = app::get('b2c')->model('contract_list')->getList('*', array('contract_no'=>$orders[0]['contract_no'])); //獲取用戶默認(rèn)收貨地址 $contract_no = $orders[0]['contract_no']; $delfile = $contracts[0]['contract_url']; $contracts[0]['contract_url'] = $uploadfile; $contracts[0]['contract_name'] = $contract_name; $contracts[0]['uptime'] = date('Y-m-d H:i:s',time()); // unset($contracts[0]['id']); $flag = app::get('b2c')->model('contract_list')->update($contracts[0],array('id'=> $contracts[0]['id'])); if($flag){ if(file_exists($delfile)){ unlink($delfile); } $return = array ( 'rsp' => 'succ', 'url' => "/paycenter-download-$contract_no.html", 'res' => '上傳成功!', ); echo json_encode($return);exit; } }else{ $return = array ( 'rsp' => 'fail', 'res' => '上傳失敗!', ); echo json_encode($return);exit; } }
