MySQL PHP jQuery-行不更新吗？

Question

I am writing a CMS and I'm stuck at updating existing products in the products table....

The problem is that every value will receive the update besides the "text" and "stock" row... they go blank....

This is my code

Form:

<form class="form-horizontal form-inline">
            <div class="form-group">
                <label class="control-label col-sm-3" for="title">Product:</label>
                <input type="text" class="form-control" id="title" name="title" placeholder="Enter new title">
            </div>
            <div class="form-group">
                <label class="control-label col-sm-3" for="price">Price:</label>
                <input type="text" class="form-control" id="price" name="price" placeholder="Enter new price">
            </div>
            <div class="form-group">
                <label class="control-label col-sm-3" for="stock">Stock:</label>
                <input type="text" class="form-control" id="stock" name="stock" placeholder="Enter new stock">
            </div>
            <div class='form-group'>
                    <label class="control-label col-sm-3" for="text">Text:</label>
                    <textarea class='form-control' rows='5' id='newPostText' name='text' placeholder='Enter new text'></textarea>
            </div>
            <div class="form-group">
                <label class="control-label col-sm-3" for="description">Description:</label>
                <input type="text" class="form-control" id="description" name="description" placeholder="Enter new description">
            </div>
            <div class="form-group">
                <label class="control-label col-sm-3" for="brand">Brand:</label>
                <input type="text" class="form-control" id="brand" name="brand" placeholder="Enter new brand">
            </div>
            <div class="form-group">
                <label class="control-label col-sm-3"  for="keywords">Keywords:</label>
                <input type="text" class="form-control" id="keywords" name="keywords" placeholder="Enter new keywords">
            </div>
            <a href="#" id="updateProductRecord" pid="<?php echo $pro_id; ?>"><button type="submit" id="submitUpdateProduct" class="btn btn-default">Submit</button></a>
            </form>

jQuery:

$("body").delegate("#updateProductRecord","click",function(event){
event.preventDefault();

var product_id = $(this).attr('pid');
updateProductRecord(product_id);

animatedLoading();
});

function updateProductRecord(product){

var title = $("#title").val();
var text = $("#text").val();
var summary = $("#description").val();
var keywords = $("#keywords").val();
var price = $("#price").val();
var stock = $("#stock").val();
var brand = $("#brand").val();

var product = product;

$.ajax({
    url :   "action.php",
    method: "POST",
    data    :   {updateProductRecord:1,pid:product,title:title,text:text,summary:summary,keywords:keywords,price:price,stock:stock,brand:brand},
    success :   function(data){
        $(".row").append(data);
    },
});

}

PHP:

if(isset($_POST['updateProductRecord'])) {

$product_id = $_POST['pid'];
$title = $_POST["title"];
$category = $_POST["brand"];
$text = $_POST['text'];
$summary = $_POST['summary'];
$keywords = $_POST['keywords'];
$price = $_POST['price'];
$stock = $_POST['stock'];
$date=date('d.m.y h:i:s');


$sql = "UPDATE products SET `title`='$title', `desc`='$summary', `price`='$price', `brand`='$category', `keywords`='$keywords', `stock`='$stock', `text`='$text' WHERE id='$product_id'";

$run_query = mysqli_query($connect,$sql);
if($run_query){

    echo "
        <div class='alert alert-success'>
            <a href='#' class='close' data-dismiss='alert' aria-label='close'>&times;</a>
            <b>Your post has been submitted.!</b>
        </div>
        ";
}
else {

    echo "
        <div class='alert alert-warning'>
            <a href='#' class='close' data-dismiss='alert' aria-label='close'>&times;</a>
            <b>Oops, something went wrong..</b>
        </div>
        ";
}

}
