php - WP Cron Job Runs On Every Page Load -


i trying wrap head around wp cron jobs , have been playing around following snippet of code, supposed send email specified email address once hour, provided of course visitor has visited site , triggered job (wp cron jobs aren't apparently real chron jobs, i've come understand).

now, job works in email gets sent email address, there 2 problems:

  1. the email gets sent multiple times per chron job
  2. cron jobs seem triggered on every page load though it's not supposed run more once hour

here's code (retrived wp_schedule_event not firing):

if ( ! wp_next_scheduled( 'prefix_hourly_event' ) ) {     wp_schedule_event( time(), 'hourly', 'prefixhourlyevent');        }  add_action( 'prefixhourlyevent', 'prefix_do_this_hourly' );  function prefix_do_this_hourly() {           wp_mail('myemail@gmail.com','cron working', 'cron working: ','',''); }

would able give me idea of why not 1 email gets sent every hour? //mega wp noob

you're checking if event scheduled , when it's not found you're registering under different name. mismatch what's causing run on every page load.

change this:

if ( ! wp_next_scheduled( 'prefix_hourly_event' ) ) {

to this:

if ( ! wp_next_scheduled( 'prefixhourlyevent' ) ) {

i'd @ whether can check schedule once rather on each page load. if writing plugin example fire on plugin activation hook.

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
