I'm really in difficulties,
I have a button:
<a href="javascript: addtocart('<?php echo get_the_ID();?>','1')" class="button add_to_cart_button product_type_simple add-to-cart">ADD TO CART</a>
And my js:
function addtocart(productid,quantity){
jQuery.ajax({
type:"GET",
url:"wp-content/themes/Teafull/addcart.php",
data:"productid="+productid+"&quantity="+quantity,
success:function(html)
{
alert('Update Success');
var sum = html;
$("#total-cart span").text(html);
$("#right-cart").empty();
$("#right-cart").load("wp-content/themes/Teafull/cart-update.php");
}
});
}My file cart-update.php:
<?php
/*
Template Name: Update Cart
*/
session_start();?>
<h3><span>Giỏ hàng</span></h3>
<?php
if($_SESSION['sizeof'] == 0){
echo '<div class="empty-cart"><p style="color: #49aba8;">No products in your cart<p><div class="clear"></div>';
}
else{
$ok = 1;
if (isset($_SESSION['cart']))
{
foreach ($_SESSION['cart'] as $k => $v)
{
if (isset($k))
{
$ok = 2;
break;
}
}
}
if($ok == 2){
$total = 0;
foreach ($_SESSION['cart'] as $key => $value)
{
$item[] = $key;
}
$str = implode(",", $item);
$total =0;
$my_query = query_posts(array('post__in' => $item,'post_type'=> 'product'));
global $post;
foreach ($my_query as $post) {
$posts_by_id[$post->ID] = $post;
}
foreach ($item as $id) {
if (!$post = $posts_by_id[$id]) continue;
setup_postdata($post);
$price = mtbxr_val('price');
$quantity = $_SESSION['cart'][$id];
echo "<ul class='cart_list product_list_widget'><li>";
echo "<a href='"; echo the_permalink(); echo "'>";
echo the_post_thumbnail();
echo "<p>";echo the_title(); echo"</p></a>";
echo "<p class='clear' id='price-sidebar'><b>Price:</b> "; echo $price;
echo "</p></li></ul>";
}
}
?>
<div class="clear"></div>
<p class="buttons">
<a href="http://localhost/tem5/?page_id=159" class="button">My cart →</a>
</p>
<div class="clear"></div>
<?php }?>I want when I click on the button "ADD TO CARD", div #right-cart load file cart-update.php.
When I click on the button "ADD TO CARD", the following error happen:
Fatal error: Call to undefined function query_posts() in C:\xampp\htdocs\tem5\wp-content\themes\Teafull\cart-update.php on line 32
But, If I refresh page, Fatal error doesn't happen.
Could anyone please help me how to solve this problem?
