我正在尝试构建一个具有自动完成功能的Web表单。用户可以填写个人代码，相关字段将显示在表单字段中。

如何将结果提取到表单字段中？

到目前为止我所做的尝试：

在Javascript中查找代码当我使用控制台并在lookup\\u code（）函数中检查var\\u dump时，我看到了所需用户的数组这是我的代码：

add_action( \'wp_head\', \'ajax_lookup_userdata\' );
/*
 * Ajax_lookup_userdata
 * Will check the string on the input field for the code.
 */

function ajax_lookup_userdata() {
?>

<script type="text/javascript">
    jQuery(document).ready(function( $ ) {

        /*Lookup the field value.*/
        var ajax_url = \'<?php echo admin_url(\'admin-ajax.php\'); ?>\';
        var codeValue = jQuery(\'li.code input\');
        var data;

        /* Limit the  keyup function... min characters and max characters. */
        $(codeValue).keyup(function(e){

            data = {
                \'action\': \'lookup_code\',
                \'codevalue\': jQuery(this).val()
            };

            // This gives me the output of the values you insert into the code-textfield.
            console.log(data.codevalue);

            jQuery.post(ajax_url, data, function(response) {
                //alert(\'Got this from the server: \' + response);
               console.log(data);
                console.log(response);
            });
        });
    });
</script>

add_action(\'wp_ajax_nopriv_lookup_code\', \'lookup_code\'); // for not logged in users


function lookup_code() {

global $wpdb;

$searchQuery = $_POST[\'codevalue\'];

$results = $wpdb->get_results(\'SELECT * FROM wp_contacts WHERE code LIKE "\'.$searchQuery.\'" \');

update_post_meta( $id, \'_wp_page_template\', \'new_template.php\' );
// Here are my values that I want to receive.
// How to pass them to the field values?
//var_dump($results[0]);

die();
}

var\\u转储（$结果[0]）；提供以下输出：

object(stdClass)#277 (8) {
  ["id"]=>
  string(1) "1"
  ["code"]=>
  string(2) "1a"
  ["firstname"]=>
  string(4) "Bert"
  ["lastname"]=>
  string(7) "Gibbers"
  ["street"]=>
  string(15) "Lazy Berry Edge"
  ["no"]=>
  string(2) "35"
  ["email"]=>
  string(18) "[email protected]"
  ["phone"]=>
  string(12) "202-555-0102"
}

非常感谢您的支持。

inputs = document.getElementsByTagName(\'input\');
for (index = 0; index < inputs.length; ++index) {
    // assign inputs[index] element values from the response.
}
