我已经搜索了很长一段时间但结果却没有成功。我试图选择单选按钮，因此在同一页面上显示其结果，但我的查询不知何故没有得到相同的记录。它说MySQL＆＃34; QUERY EMPTY＆＃34;。请告诉我在哪里做错了。这是我的代码。非常感谢帮助。

Does this need to be strictly PHP and MySQL? Can we include some JavaScript/jQuery? While this doesn't answer your question directly, I hope it helps.
For your issue, I would detect the change event of your radio field and fire off a quick jQuery $.post to process the selection.
When your JavaScript sends a POST request to your PHP, you would run your PHP logic and return (or echo) the result. This can then be "digested" by your JavaScript. Here is a simple/rough example using jQuery and PHP. Adapt to your needs:
<script>
// # on ready
$(function() {
// # current document - assumes you'll be submitting to self
var self = document.location.href;
// # when changing the user radios
$('input[type=radio][name=users]').change(function() {
// # grab the value of the radio and create a js array to post
var postData = {'users': $(this).val()};
// # post the postData to your PHP
$.post(self, postData).done(function(data, status, xhr) {
// # assumes you're returning JSON data
data = jQuery.parseJSON(data);
// # add your logic here
console.log('POST Response', data);
// # update an element with the returned data or response:
$('#example').before('<div>'+ data +'</div>');
});
});
});
</script>
Regarding your PHP code, as other users have suggested, you're using mysql_ functions that are no longer supported on modern versions of PHP. You're quickest and dirtiest adjustment, without rewriting everything, is to use mysqli_ functions (notice the additional 'i').
You're already listening for the $_POST['users'] parm, so the only addition I would recommend is to actually use that $users[] array. I could get into re-writing the PHP so it makes sense, but here is a quick adjustment to your existing code:
<?php
$users = array();
if(isset($_POST['users']) && $_POST['users'] == 'approved'){
$query = "SELECT * FROM tbl_user WHERE type = 3 AND status = 1";
} else if(isset($_POST['users']) && $_POST['users'] == 'unapproved') {
$query = "SELECT * FROM tbl_user WHERE type =3 and status = 0";
} else if (isset($_POST['users']) && $_POST['users'] == 'all') {
$query = "SELECT * FROM tbl_user WHERE type =3";
}
if ($result = $mysqli->query($query)) {
/* fetch associative array */
while ($row = $result->fetch_assoc()) {
$users[] = $row;
}
// # encode your $row array into JSON and echo for JavaScript
echo json_encode($users);
// # free result set
$result->free();
}
?>
While this isn't a complete solution, I hope it points you in the right direction.
A couple things to note - you'll need to adjust your MySQL connection code if you're to use mysqli_ functions. You'll also need to include jQuery (ideally from CDN) for that JavaScript to work (or you could rewrite it to not use a library like jQuery). This should return the results of your query to your JavaScript. The result should be available as "data" in your js. I've added a console.log so you can view the response in your inspector.
Good Luck!
