jQuery验证远程响应格式 [英] jquery validate remote response format

问题描述

尝试使用远程方法验证昵称

Trying to validate nickname using the remote method

rules: {
     nickname: {
           required: true,
           remote: "checknick.php"
     }
}

checknick在这里

And checknick is here

$name = addslashes($_POST['nickname']);

$sql="select * from names where nickname='$name'";
$result=mysql_query($sql);
$num_rows = mysql_num_rows($result);

if($num_rows > 0 ) {
   $valid='false';
} else {
   $valid = 'true';
}


echo $valid;

这对我而言无效.有人可以帮我吗?

This isn't validating for me. Can anybody help me out here.

推荐答案

您正在使用哪个验证插件?

Which validation plugin are you using?

我会尝试对响应进行json编码

I would try json encoding the response:

echo json_encode($valid);
