Question

我试图通过ajax和表单数据方法获取已选择上传的文件的名称。我目前在WordPress工作，下面是我的代码。我希望通过该函数返回所选文件的名称。 Null在$_FILES中返回，也请我如何上传此文件，但第一个障碍是我的$_FILES['file']始终为null。感谢

Html上传表单

[testupload]
<form id="test" action="" method="post" enctype='multipart/form-data'>

<input id="files" type="file" name="file" style="margin-top:12px;">

<input name="testupload" type="submit" value="upload"/>
</form>
<div id="result"></div>

Ajax代码

jQuery(function ($) {
    $("#test").submit(function (e) { //form is intercepted
    e.preventDefault();
var sent = $(this).serializeArray();

var sentdata = $(this).serializeArray();

        //$("#result").html("zeeshan aslam durrani");
        alert("jquery file is connected");
        //serialize the form which contains secretcode
                var file = jQuery(document).find('input[type="file"]');
        formData = new FormData();
        var image = $('#files')[0].files[0];
        formData.append("file",image);
        alert(formData)

        //Add the additional param to the data        
        sent.push({
            name: 'action',
            value: 'testfunction',
            data: formData
        })

        //set sentdata as the data to be sent
        $.post(yes.ajaxurl, sent, function (res) { //start of funciton
            //$("#myresult").append(res.l);
            $("#result").html("");
            $("#result").html(res);
            alert(res);
 //$.parseJSON(data);
            return false;
        } //end of function
        ,
        'json'); //set the dataType as json, so you will get the parsed data in the callback
    });  // submit end here

    });

PHP代码

//test upload

    add_action( 'wp_ajax_testfunction', 'testfunction' );
add_action( 'wp_ajax_nopriv_testfunction', 'testfunction');

add_shortcode('testupload','testupload');

function testupload()
{

// register & enqueue a javascript file called globals.js
wp_register_script( 'testscript', get_stylesheet_directory_uri() . "/js/ajaxinsert.js", array( 'jquery' ) ); 
wp_enqueue_script( 'testscript');

// use wp_localize_script to pass PHP variables into javascript
wp_localize_script( 'testscript', 'yes', array( 'ajaxurl' => admin_url( 'admin-ajax.php' ) ) );

}

function testfunction()
{
//echo json_encode("My name is khan");
echo json_encode($_FILES['file']);
die();  
}

null中始终返回$_FILES ...请帮助和谢谢

$ _FILES始终为空
