时间：2011-01-03 作者：Atif

我想写一个功能，以电子邮件给我的网址时，我的主题被激活。

当主题被激活时，钩子会启动什么？

我这里有代码，只需将文件命名为theme\\u activation\\u hook。php喜欢在网站上复制这个。

<?php
/**
 * Provides activation/deactivation hook for wordpress theme.
 *
 * @author Krishna Kant Sharma (http://www.krishnakantsharma.com)
 *
 * Usage:
 * ----------------------------------------------
 * Include this file in your theme code.
 * ----------------------------------------------
 * function my_theme_activate() {
 *    // code to execute on theme activation
 * }
 * wp_register_theme_activation_hook(\'mytheme\', \'my_theme_activate\');
 *
 * function my_theme_deactivate() {
 *    // code to execute on theme deactivation
 * }
 * wp_register_theme_deactivation_hook(\'mytheme\', \'my_theme_deactivate\');
 * ----------------------------------------------
 * 
 * 
 */

/**
 *
 * @desc registers a theme activation hook
 * @param string $code : Code of the theme. This can be the base folder of your theme. Eg if your theme is in folder \'mytheme\' then code will be \'mytheme\'
 * @param callback $function : Function to call when theme gets activated.
 */
function wp_register_theme_activation_hook($code, $function) {
    $optionKey="theme_is_activated_" . $code;
    if(!get_option($optionKey)) {
        call_user_func($function);
        update_option($optionKey , 1);
    }
}

/**
 * @desc registers deactivation hook
 * @param string $code : Code of the theme. This must match the value you provided in wp_register_theme_activation_hook function as $code
 * @param callback $function : Function to call when theme gets deactivated.
 */
function wp_register_theme_deactivation_hook($code, $function) {
    // store function in code specific global
    $GLOBALS["wp_register_theme_deactivation_hook_function" . $code]=$function;

    // create a runtime function which will delete the option set while activation of this theme and will call deactivation function provided in $function
    $fn=create_function(\'$theme\', \' call_user_func($GLOBALS["wp_register_theme_deactivation_hook_function\' . $code . \'"]); delete_option("theme_is_activated_\' . $code. \'");\');

    // add above created function to switch_theme action hook. This hook gets called when admin changes the theme.
    // Due to wordpress core implementation this hook can only be received by currently active theme (which is going to be deactivated as admin has chosen another one.
    // Your theme can perceive this hook as a deactivation hook.
    add_action("switch_theme", $fn);
}

没有专门的挂钩。我见过两种方法：

switch_theme 勾选主题-Execute “Setup” Code on Activation only?Set options on activation Themes

我想指出的是，未经用户同意通过电子邮件向自己发送任何信息（并且在激活状态下运行任何操作都没有机会请求此类信息）可能被视为不合适。

Wordpress现在提供这个钩子作为after_switch_theme. 您可以这样使用它：

add_action(\'after_switch_theme\', \'my_theme_activation\');

function my_theme_activation () {
  // DO ALL THE THINGS
}

您可以使用switch_theme 钩子运行主题代码deactivation 也

将此代码放在functions.php

<?php if ( is_admin() && isset($_GET[\'activated\'] ) && $pagenow == "themes.php" ) {
// do your stuff
$url = get_site_url();
// The message
$message = "a new wordpress theme is activated on $url ";

// In case any of our lines are larger than 70 characters, we should use wordwrap()
$message = wordwrap($message, 70, "\\r\\n");

// Send
wp_mail(\'[email protected]\', \'theme geactiveerd\', $message);
}

?>

更换[email protected] 使用您自己的电子邮件地址。

希望有帮助。

结束
