主题don\'t currently have activation/deactivation/installation/uninstallation hooks.

你最好的选择是以某种方式“伪造”它，也许是使用一个只执行一次的函数，基于该函数执行时切换的开关。e、 g.：

<?php
function wpse45817_theme_activation() {
    // globalize our switch
    global $wpse45817_theme_activation_switch;
    // Check to see if the switch is set
    if ( isset( $wpse45817_theme_activation_switch ) ) {
        return;
    } else {
        // EXECUTE YOUR THEME-ACTIVATION CODE HERE
        //
        //
        // Toggle Theme activation switch
        $wpse45817_theme_activation_switch = true;
    }
}
add_action( \'after_setup_theme\', \'wpse45817_theme_activation\' );
?>
