主题激活钩

我想编写一个函数，以在激活主题后通过电子邮件将网站的URL发送给我。

激活主题时启动的挂钩是什么？

我在这里有该代码，只需在网站上将文件命名为theme_activation_hook.php并复制它即可。

<?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);
}

我编写了一个提供可靠的激活/停用主题挂钩的代码。请检查出来，让我知道你们的想法！

没有专门的挂钩。我见过几种方法：

• switch_theme与检查主题挂钩- 仅在激活时执行“设置”代码？
• 主题激活后检测管理页面- 设置激活主题选项

我想指出，未经用户同意而将任何信息通过电子邮件发送给自己（并且在激活时运行任何内容都没有机会要求此类信息）可能被视为不合适。

现在，WordPress将此钩子提供为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
}

您也可以使用该switch_theme挂钩在主题停用上运行代码。

资料来源：http : //codex.wordpress.org/Plugin_API/Action_Reference/after_switch_theme

将此代码放在您的顶部 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('mail@yourdomain.com', 'theme geactiveerd', $message);
}

?>

mail@yourdomain.com用您自己的电子邮件地址替换。

希望能帮助到你。
