这是我的ajax代码：
$(function(){
var cntUp = 0;
var btnUpload=$('#upload_pdf');
var status=$('#status');
new AjaxUpload(btnUpload, {
action: 'uplod_estimate_file.php',
data: {saleid: $("#hid_saleid").val()},
name: 'uploadfile_test',
onSubmit: function(file, ext){
if (! (ext && /^(jpg|pdf|jpeg)$/.test(ext))){
// extension is not allowed
alert('Only JPG, PDF or JPEG files are allowed');
return false;
}
this.setData({
'saleid': $("#hid_saleid").val()
});
status.text('Uploading...');
},
onComplete: function(file, response){
if (response.toLowerCase().indexOf("success") >= 0 ) {
alert(response);
/*
var image='<img src="uploads/'+saleid+'/'+fname+'" alt="" width="131px" height="125px"/>';
$("#img0").html(image);*/
} else{
$('<li></li>').appendTo('#files').text(file).addClass('error');
//alert('error');
}
}
});
});
这是表格：
<form name="frmvehdetails" id="frmvehdetails" method="post">
<table cellpadding="3">
<tr>
<td valign="top">VIN</td>
<td>
<input class="frmIn" size="30" name="car-vin" id="car-vin" type="text" value="" />
<input onclick="lookupVIN()" name="btnVin" type="button" value="Lookup" />
<br/>
<div id="vinDet" style="line-height: 20px; margin-bottom: 10px; margin-top: 10px;"></div></td>
</tr>
<tr>
<td>Year</td>
<td><select name="car-years" id="car-years">
</select></td>
</tr>
<tr>
<td>Make</td>
<td><select name="car-makes" id="car-makes">
</select></td>
</tr>
<tr>
<td>Model</td>
<td><select name="car-models" id="car-models">
</select></td>
</tr>
<tr>
<td>Milage</td>
<td><input type="text" name="car-milage" id="car-milage" value="" class="frmIn" /></td>
</tr>
<tr>
<td>Repair Estimate</td>
<td><input type="text" value="" id="car_estimate" name="car_estimate" class="frmIn"></td>
</tr>
<tr>
<td> </td>
<td><div id="upload_pdf" style="margin-bottom:10px;" >
<span>Upload File</span></div></td>
</tr>
<tr>
<td>Reserve Price</td>
<td><input type="text" value="" id="car_reserve" name="car_reserve" class="frmIn"></td>
</tr>
<tr>
<td> </td>
<td>
<input type="button" name="sub" value="<< Previous " class="previous-product" />
<input type="button" id="sub" name="sub" value="Next >>" class="next-product" onclick="validatevehicle();" /></td>
</tr> <tr>
<td> </td>
<td id="v_errmsgs" style="color:red">
</td>
</tr>
</table></form>
<input type="hidden" id="hid_saleid" name="hid_saleid" value="" />
这是 uplod_estimate_file.php：
<?php
session_start();
$sub = "";
$uploaddir = "";
if(isset($_POST['saleid'])){
if($_POST['saleid']){
$sub = $_POST['saleid'];
}else{
$sub = "";
}
}else{
$sub = "";
}
if($sub){
$uploaddir = './uploads/'.$sub."/";
}else{
$uploaddir = './uploads/';
}
$file = $uploaddir . basename($_FILES['uploadfile_test']['name']);
if(move_uploaded_file($_FILES['uploadfile_test']['tmp_name'], $file)){
echo "success";
}else{
echo "error";
}
?>
但是当我使用它时，我得到了错误未定义的索引'uploadfile_test'。我该如何解决这个问题？
