Question

我正在尝试使用ajax将数据插入数据库。问题是除了在数据库中插入数据之外，一切都有效。当我点击提交按钮时，我收到正确的消息＆＃34;您已经订阅了＃34; ，只是它没有在数据库中插入数据。并且不明白为什么。

我有dbconn.php

<?php
$db = new mysqli($dbhostname, $dbuser, $dbpass, $dbname);
if ($db->connect_errno) {
  echo "Failed to connect to MySQL: (" . $db->connect_errno . ") " . $db->connect_error;
}
?>

common-functions.php

<?php
  require_once('dbconn.php');
  function subscribe() {
    global $db;
    if(isset($_POST['semail'], $_POST['sname'])) {
      $name = $_POST['sname'];
      $email = $_POST['semail'];
      $db->query("INSERT INTO subscribers (`name`, `email`, 'confirmed') VALUES ('".$db->escape_string($name)."', '".$db->escape_string($email)."', 0)");
      echo "You have been subscribed";
    }
  }
subscribe();
?>

subscribe.php

HTML

  <form name="subscribe" class="subscribe">
    <label class="lablabel">Name:</label><input type="text" class="subscribe-field" id="sname" name="sname"></br>
    <label class="lablabel">Email:</label><input type="text" class="subscribe-field" id="semail" name="semail"> 
    <input type="submit" id="ssub" value="Subscribe">
  </form>

AJAX

<script type="text/javascript">
$(document).on('submit','.subscribe',function(e) {
  e.preventDefault(); // add here
  e.stopPropagation(); // add here
  $.ajax({ url: 'lib/common-functions.php',
      data: {action: 'subscribe',
        sname: $("#sname").val(),
        semail: $("#semail").val()},
    type: 'post',
    success: function(output) {
        alert(output);
    }
 });
});
</script>

删除引号并在此处用反引号代替

$db->query("INSERT INTO subscribers (`name`, `email`, 'confirmed') 
                                                      ^         ^

Ajax没有将数据插入数据库
