thanks for your help.

Answer 1

您的文件应返回JSON，然后可以使用它并使用jquery填充字段。

Answer 2

Variable scope is not the problem here so you can take out global $pilihdomain.

The only way that you'll be able to access the value of that variable is if you pass it as a GET or POST parameter.

search_request.php

var pilihdomain = '<?php echo $pilihdomain ?>';
$.ajax({
    url: 'http://localhost/kejar/code/search_response.php?q=' + search_value + '&pilihdomain=' + pilihdomain,
    success: function(data){
        // Display the results
        $('#search_results').html(data);
    }
})

In search_response.php ,

$pilihdomain = $_GET['pilihdomain'];
