Question

我正在Wordpress中创建一个自定义插件，该插件将允许用户插入一些信息。我还在数据库中创建了一个名为“ Patientinfo”的表，以及它们的属性（全名，耐心，性别，生日，电话号码，注册日期）

单击提交按钮后，它仍然无法保存在数据库中。我缺少将其连接到数据库的什么代码？

这是我的代码的片段

<?php

global $wpdb;

?>
<h1>Enter New Patient's Data:</h1>
<form method="post" enctype="multipart/form-data">
  <b>Full name:
  <input type="text" name="fullname" required>
  <p>Patient's ID:
  <input type="text" name="patientid" required></p>
  <p>Gender: <input type="radio" name="gender" value="male" required> Male
  <input type="radio" name="gender" value="female"> Female</p>
  <p>Birthday:
  <input type="date" name="bday" required></p>
  <p>Phone number:
  <input type="text" name="phonenumber" required></p>
  <p>Registration date:
  <input type="date" name="regisdate" required></p>



  </b>
  <br>
  <input type="submit" name="submit" value="Submit">
</form>


<?php
if($wpdb->insert(
     'patientinfo',
     array(
        'fullname' => $fullname,
        'patientid' => $patientid,
        'gender' => $gender,
        'bday' => $bday,
        'phonenumber' => $phonenumber,
        'regisdate' => $regisdate
        )
 ) == false) wp_die('Database insertion failed');
 else echo 'Database insertion successful';

编辑：var_dump（$ wpdp）给了我

Answer 1

出现任何错误吗？

应该更像这样：

$wpdb->insert(
 'patientinfo',
 array(
    'fullname' => $_POST['fullname'],
    'patientid' => $_POST['patientid'],
    'gender' => $_POST['gender'],
    'bday' => $_POST['bday'],
    'phonenumber' => $_POST['phonenumber'],
    'regisdate' => $_POST['regisdate']
    )
 )

然后再次检查表名和列名。
