我正在尝试通过ajax开发添加到购物车的功能,问题是无论我添加到购物车的哪个产品,它都会添加列表中的最后一项,然后在点击任何其他产品时递增相同的产品。这是我的代码: -
<?php
$i = 1;
while($row = mysqli_fetch_array($run_products)){
$op_id = $row['option_id'];
echo "<tr>";
echo "<td>" . $i . "</td>";
echo "<td>" . $row['option_desc'] . "</td>";
echo "<td>
<form action='' method='post' class='p_form'>
<input type='text' name='product_id' value='$op_id' pid='$op_id'>
<input type='text' name='quantity' value='1' pid='$op_id'>
<input class='btn btn-primary add' type='submit' name='add_to_cart' value='Add to Cart' id='product' pid='$op_id'>
</form>
</td>";
echo "</tr>";
$i++;
}
?>
这是jquery:
<script type="text/javascript">
$(document).ready(function(){
$(document).on('click','.p_form',function (event) {
event.preventDefault();
var element = $(this);
var id = element.attr("pid");
//alert(id);
$.ajax({
url: 'action.php',
method: 'post',
//data: {id:id},
data:$('.p_form').serialize(),
success: function(data){
$('#message').html(data);
}
});
return false;
});
});
</script>
这里是action.php
,如果最后一个id是4,那么$ product_id总是返回4(例如)
if (!empty($_POST)){
$product_id = $_POST['product_id'];
echo $product_id;
}

需要像下面这样做: -
<script type="text/javascript">
$(document).ready(function(){
$(document).on('click','.add',function (event) {//instead of form click add event on form button click
event.preventDefault();
var element = $(this);
var id = element.attr("pid");
//alert(id);
$.ajax({
url: 'action.php',
method: 'post',
data:element.parent('.p_form').serialize(), //serialize clicked button parent form
success: function(data){
$('#message').html(data);
}
});
return false;
});
});
</script>

单击按钮时触发单击事件,而不是单击表单
这对每种产品都适用。
<script type="text/javascript">
$(document).ready(function(){
$(document).on('click','.add',function (event) {
event.preventDefault();
var element = $(this);
var id = element.attr("pid");
//alert(id);
$.ajax({
url: 'action.php',
method: 'post',
data: {id:id}, //send id of product you wish to add
success: function(data){
$('#message').html(data);
}
});
return false;
});
});
</script>
在服务器端:
if (!empty($_POST)){
$product_id = $_POST['id'];//get only that id posted in ajax call
echo $product_id;
}
