I found a script that check status of a url. Now i'm trying to integrate it with wordpress. This is the code:
<?php
/*
Plugin Name: checkOnline Status
Version: 0.1
*/
add_action( 'cO_cron_hook', 'CheckRemoteService' );
if( !wp_next_scheduled( 'cO_cron_hook' ) ) {
wp_schedule_event( time(), 'daily', 'cO_cron_hook' );
}
register_deactivation_hook( __FILE__, 'bl_deactivate' );
function bl_deactivate() {
$timestamp = wp_next_scheduled( 'cO_cron_hook' );
wp_unschedule_event($timestamp, 'cO_cron_hook' );
}
function CheckRemoteService($atts) {
extract(shortcode_atts(array(
'url' => 'http://',
'cache' => '600', // 60*10 (10 minutes)
'online' => 'Online', // Custom online msg
'offline' => 'Offline' // Custom online msg
), $atts));
$CachedStatus = 'cstatus_' . $url;
$cachedposts = get_transient($CachedStatus);
if ($cachedposts !== false) {
return $cachedposts;
} else {
// Sometimes its best to change to a custom agent message
// so you know where requests are coming from.
$agent = "Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Win64; x64; Trident/5.0)";
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL,$url );
curl_setopt($ch, CURLOPT_USERAGENT, $agent);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch,CURLOPT_VERBOSE,false);
curl_setopt($ch, CURLOPT_TIMEOUT, 5);
curl_setopt($ch, CURLOPT_NOBODY, 1);
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch,CURLOPT_SSLVERSION,3);
curl_setopt($ch,CURLOPT_SSL_VERIFYHOST, FALSE);
curl_exec($ch);
$httpcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
if($httpcode >= 200 && $httpcode < 400) {
return $online;
} else {
return $offline;
}
set_transient($CachedStatus, $return, $cache);
return $return;
}
}
add_shortcode('checkmyurl','CheckRemoteService');
?>
What i want is run this code only once daily. How can i make it not run when refresh or visit a page where i use shortcodes ? I need display status of about 50 sites and page takes more than 10 sec to load now. Sorry for this simple question (i'm a noob to this) but i can't find a solution. Thanks.
EDIT. Solved using http://wordpress.org/plugins/crony/

You can use wp_schedule_event()
to schedule recurring tasks.
wp_schedule_event()
(documentation):
Schedules a hook which will be executed by the WordPress actions core on a specific interval, specified by you. The action will trigger when someone visits your WordPress site, if the scheduled time has passed. See the Plugin API for a list of hooks.
To schedule an event daily, you'd do something like this:
function someFunc() {
wp_schedule_event( time(), 'daily', 'mydailyEventHook');
}
Hope this helps!
