我想从直接目录上载文件。但在我的代码中，它将打开媒体库，然后选择要上载的文件

jQuery(\'#t_pdf\').on("click", function(){

// alert("got it");

    var image = wp.media({

        title: "Upload PDF for Assignments",

        multiple: false

    }).open().on("select",function(){

        var uploaded_image = image.state().get("selection").first();

        var getpdf = uploaded_image.toJSON().url;

        jQuery("#show-pdf").html("<a class=\'btn btn-success\' target=\'_blank\' href=\'"+getpdf+"\'>View PDF</a>");

        jQuery("#sub_file_pdf").val(getpdf);

    });

});

当我单击按钮时

<input type="button" class="btn btn-info" id="t_pdf" value="Upload File" required>
<span id="show-pdf"></span>
<input type="hidden" id="sub_file_pdf" name="sub_file">

它将按照脚本打开媒体库，希望从direct files目录上载文件并将其上载到特定的自定义文件夹。

有人能帮我找到这个吗？

add_action( \'wp_ajax_file_upload\', \'file_upload_callbacks\' );
add_action( \'wp_ajax_nopriv_file_upload\', \'file_upload_callbacks\' );


function file_upload_callbacks() {
    
    $arr_img_ext = array(\'application/pdf\');
 if (in_array($_FILES[\'file\'][\'type\'], $arr_img_ext)) {
     $upload = wp_upload_bits($_FILES["file"]["name"], null, file_get_contents($_FILES["file"]["tmp_name"]));
     //$upload[\'url\'] will gives you uploaded file path

     //var_dump($upload[\'url\']);

     wp_send_json( $upload[\'url\'] );
 }
 wp_die();
}
