我正在创建一个WordPress插件,当插件被激活时,我需要安排一个cron作业,每5分钟运行一次.

这是我的代码;

// Register plugin activation hook
function my_plugin_activate() {
    if( !wp_next_scheduled( 'my_function_hook' ) ) {  
       wp_schedule_event( time(),'5','my_function_hook' );  
    }
}
register_activation_hook( __FILE__,'my_plugin_activate' );

// Register plugin deactivation hook
function my_plugin_deactivate(){
    wp_clear_scheduled_hook('my_function_hook');
}
register_deactivation_hook(__FILE__,'my_plugin_deactivate');

// Function I want to run when cron event runs
function my_function(){
    //Function code
}
add_action( 'my_function_hook','my_function');

当我使用这个插件https://wordpress.org/plugins/wp-crontrol/检查cron事件时,没有添加任何内容,我期待添加一个以5分钟为间隔运行’my_function’的cron事件,我没有错误

见：
wp_schedule_event()

Valid values for the recurrence are hourly,daily,and twicedaily.
These can be extended using the ‘cron_schedules’ filter in
wp_get_schedules().

因此,您只需添加每5分钟运行一次的自定义计划.

<?php // Requires PHP 5.4+.

add_filter( 'cron_schedules',function ( $schedules ) {
    $schedules['every-5-minutes'] = array(
        'interval' => 5 * MINUTE_IN_SECONDS,'display'  => __( 'Every 5 minutes' )
    );
    return $schedules;
} );

if( ! wp_next_scheduled( 'my_function_hook' ) ) {  
    wp_schedule_event( time(),'every-5-minutes','my_function_hook' );  
}
