Question

我使用Jquery和Ajax向php页面提交包含text input和file input的表单，但在提交之前，我想在提交之前验证文本输入。< / p>

以下是表单页面

            <form id="registrationForm"  method="POST"  name="registrationForm" enctype="multipart/form-data">

                <input type="text"  name="firstName" id="firstName" />

                <input type="file" name="file" id="file" />

                <button type="submit"> UPLOAD</button>

            </form>

和Javascript页面

 $('#registrationForm').validate({
        rules: {
            firstName:{
                required: true
            }
        },
        message:{
            firstName: {
                required: "Please Enter Name"
            }
        },


    submitHandler : function(){

      //grab all form data  
      var formData = new FormData(this);

      $.ajax({
        url: 'submitPage.php',
        type: 'POST',
        data: formData,
        async: false,
        cache: false,
        contentType: false,
        processData: false,
          success: function(data) {  
            $('#message').html(data);  
            $('#message').html(data).hide().fadeIn(1500,function(){$('#message')});
            } 
        });

    }
    });

PHP页面是接收页面

        <?php
            $firstName=$_POST['firstName'];
            $file=$_FILES['file']['name'];

            echo $firstName;
            echo $file;

         ?>

这在php接收页面上返回null。我真的希望有人可以帮助我。感谢。

      var formData = new FormData(document.querySelector("form"));

      $.ajax({
        url: 'submitPage.php',
        type: 'POST',
        data: formData,
