I have an select menu that submits without reloading the page as follows:
<select id="option" name="option">
<option value="15">15/option>
<option value"30">30</option>
<option value"90">90</option>
</select>
It will submit to the current page as follows, without reloading the page
<script type="text/javascript">
$('#option').change(function(){
var option_val = $(this).val();
$.ajax({
type: 'post',
url: "$_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];",
data: "option="+option_val,
success: function(data)
{
window.alert(data)
}
});
});
</script>
The result of a change in the option menu is an popup window with all the code of the page echoed back.
What i want to do on the page is use the $_POST['option'] that is submitted and recalculate a price for example
<body>
//some code and div's
<?php
if (isset($_POST['option'])) {
$option = $_POST['option'];
$price= $row_product['price'] + $option;
echo $price;
} ?>
</body>
The are several places where I would like to use the submitted option value
Any help welcome Sorry if it is very obvious
