Question

我再次。

我有一些PHP生成的错误，如下所示：

if (strlen($event_name) < 1){ echo $result['error'] = "<li>You must enter an event name</li>";}
if (strlen($venue_name) < 1){ echo $result['error'] = "<li>You must enter a venue name</li>";}
if (strlen($event_date) < 1){ echo $result['error'] = "<li>You must enter an event date - if not please write TBC</li>";}
if (strlen($address_l1) < 1){ echo $result['error'] = "<li>You must enter an address</li>";}
if (strlen($postcode) < 1){ echo $result['error'] = "<li>You must enter a postcode</li>";}
if (strlen($country) < 1){ echo $result['error'] = "<li>You must enter a country</li>";}

然后在最后我得到了：

echo json_encode($result);

要将这些错误打印到我的OL，我得到了这个：

$('#errorbox').html(result.error);

然而，没有任何结果......因为它没有出现。

编辑：这是在完成AJAX之后调用的函数：

}, function(result) {
        if (result.success == true) {
            $('#errorbox').html(result);
        } else if (result.success == false) {
            $('#errorbox').html("Not working dude!");
        }
    }, 'json');
    return false;
}

您的代码会覆盖下一个错误。为避免这种情况，请连接消息：

$result['error'] = '';
if (strlen($event_name) < 1){ $result['error'] .= "<li>You must enter an event name</li>";}
if (strlen($venue_name) < 1){ $result['error'] .= "<li>You must enter a venue name</li>";}
if (strlen($event_date) < 1){ $result['error'] .= "<li>You must enter an event date - if not please write TBC</li>";}
if (strlen($address_l1) < 1){ $result['error'] .= "<li>You must enter an address</li>";}
if (strlen($postcode) < 1){ $result['error'] .= "<li>You must enter a postcode</li>";}
if (strlen($country) < 1){ $result['error'] .= "<li>You must enter a country</li>";}

同时确保HTML包含标识为ul的{{1}}或ol div，并且正确加载了jQuery。

您可能希望使用+=，而不是=，后者会覆盖以前的值。您还希望将echo语句放在if的字符串中。你原来的代码在顶部有很多瑕疵;剩下的东西来自回应各种<li> s。

$result['error']="";
if (strlen($event_name) < 1) { $result['error'] .= "<li>You must enter an event name</li>";}
if (strlen($venue_name) < 1) { $result['error'] .= "<li>You must enter a venue name</li>";}
if (strlen($event_date) < 1) { $result['error'] .= "<li>You must enter an event date - if not please write TBC</li>";}
if (strlen($address_l1) < 1) { $result['error'] .= "<li>You must enter an address</li>";}
if (strlen($postcode) < 1) { $result['error'] .= "<li>You must enter a postcode</li>";}
if (strlen($country) < 1) {  $result['error'] .= "<li>You must enter a country</li>";}

现在，对PHP页面的GET请求应该有效。
