Answer 1

You have two php....let say page.php and ajax.php. If you call ajax.php from ajax in page.php you must write variables from php to javascript with something like

var data1 = <?= $data1 ?>;
var data2 = <?= $data2 ?>;

and then add these variables to ajax call.

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>

<script type="text/javascript">

var ajax_value1 = $("#ajax_value1").val();

var ajax_value2 = $("#ajax_value2").val();

 $.ajax({

     type: "POST",

     url: 'sample.php?ajax_value1='+value1+'&value2='+ajax_value2,

     //Specify the datatype of response if necessary

     data: $("#your_form_id").serialize(),

     success: function(data){

     }

});

</script>


<!-- Set your ajax value in html input fields -->

<input type="text"  name="ajax_value1" id="ajax_value1" value="<?php echo $ajax_value1;?>" > 

<input type="text"  name="ajax_value2" id="ajax_value2" value="<?php echo $ajax_value2;?>" >
