"register_activation_hook"功能在WordPress中不起作用(应用程序服务器)

Question

Appserv(本地主机(安装在我自己的计算机上。我正在尝试创建一个 mysql 表。但不幸的是，register_activation_hook功能不起作用。

我正在尝试使用下面的create_table函数创建一个表。

<?php
function create_table()
{
global $wpdb;
$charset = $wpdb->get_charset_collate();
$tablo_adi = $wpdb->prefix."bilgiler";
$sql = "CREATE TABLE $tablo_adi(
id mediumint(9) NOT NULL AUTO_INCREMENT,
name VARCHAR(300) NOT NULL,
mail VARCHAR(300) NOT NULL,
phone VARCHAR(300) NOT NULL,
UNIQUE KEY id (id)) $charset;";
require_once(ABSPATH. "wp-admin/includes/upgrade.php"); 
dbDelta($sql);

} register_activation_hook(__FILE__,'create_table'); ?>

包含代码的页面：

<?php

add_action("admin_menu","ders_iki");
function ders_iki()
{
add_menu_page("Ders iki - Title","ders-iki-menu","manage_options","ders-iki","eklenti_icerigi","dashicons-wordpress-alt");
}
function eklenti_icerigi()

<?php
function create_table()
{
global $wpdb;
$charset = $wpdb->get_charset_collate();
$tablo_adi = $wpdb->prefix."bilgiler";
$sql = "CREATE TABLE $tablo_adi(

isim VARCHAR(300) NOT NULL,

telefon VARCHAR(300) NOT NULL,
UNIQUE KEY id (id)) $charset;";
require_once(ABSPATH. "wp-admin/includes/upgrade.php"); 
dbDelta($sql);


} register_activation_hook(__FILE__,'create_table');

if (isset($_POST['gonder'])) 
{
global $wpdb;
$wpdb->insert($wpdb->prefix."bilgiler",
array(
"isim" => $_POST['isim'],
"eposta" => $_POST['eposta'],
"telefon" => $_POST['telefon']
));}

}

这一切都对我有用。我能够在提交时激活插件并将数据添加到表中。
