I created a form with a hidden input form that submits values to a PHP script and stores each value in a session array by reloading the page using AJAX. It returns an HTML success alert message to <p id ="msg"></p>. I need information on how to send $count to <p id="count"></p> and success alert message to <p id=" msg"></pphpcngt phpcn cnendcphpcn in success:php dot help AJAX. I also want the success alert to disappear after showing for 3 seconds. Below is my code:
my_add_cart.php
<?php
session_start();
$_SESSION['title'][]=$_POST['title'];
$_SESSION['price'][]=$_POST['price'];
$_SESSION['img_src'][]=$_POST['img_src'];
$count = count($_SESSION["title"]);
echo $count;
echo '<div class="alert">
<span class="closebtn" onclick="this.parentElement.style.display=\'none\';">×</span>
<center>Product added successfully to cart.</center>
</div>';
exit();
?>
The above is my_add_cart.php, below is my HTML and javascript:
<script type="text/javascript">
function clickButton(){
var title=document.getElementById('title').value;
var price=document.getElementById('price').value;
var img_src=document.getElementById('img_src').value;
$.ajax({
type:"post",
url:"my_add_cart.php",
data:
{
'title' :title,
'price' :price,
'img_src' :img_src
},
cache:false,
success: function (html)
{
$('#msg').html(html);
}
});
return false;
}
</script>
<html>
<p id="msg"></p>
<p id="count"></p>
<form onsubmit="clickButton()">
<input type="hidden" value="<? echo $title ?>" name = "title" id="title" >
<input type="hidden" value="<? echo number_format($price); ?>" name = "price" id="price" >
<input type="hidden" value="<? echo "https://mikeandcathy.com.ng/admin/UploadFolder/".$row_product_img[0]; ?>" name = "img_src" id="img_src">
<button type="submit" id="add_to_cart" name="add_to_cart" class="btn btn-outline-secondary btn-sm" value="Add to cart" onclick="return clickButton();">Add Cart</button>
</form>
</html>

I recommend converting your server code to json api
solution
Change
my_add_cart.phpto this$count, 'message' => '
× Product added successfully to cart.
';
]
);
exit();
?>
Change your frontend code to this
