This is unreal, all the great stuff I learned over the short time span. Got a lot of new ideas and things to learn from this small weekend. I wanted to put together what I found most interesting in this blog post more as a list and reminder for myself but also for anybody reading this. It may start you off on a learning quest 🙂

This is not my attempt at a complete summary of WCPHX2014, I am merely trying to note down the things I found most interesting and acredit the person how got me to think in that direction via their twitter handle.

set_transient( $transient, $value, $expiration );	
get_transient( $transient );
delete_transient( $transient );
wp_remote_get( $url, $args );	
wp_remote_retrieve_body( $response );

http://codex.wordpress.org/Transients_API

set transient for db queries, external api calls, any data task that takes time

Tip: hook in logical spots to delete transient
Example delete transient on post save

add_action( 'save_post', schurpf_del_transient );
function schurpf_del_transient()
{
	delete_transient('schurpf_my_transient' );
}

In our generation, there are divers options for those ones who suffer from erectile disfunction. You may have heard about “canadian pharmacy online cialis“. More info about the question available at “canadian pharmacy cialis 20mg“. Why it happen? Can sexual disorders in men be prevented? If you get any prescription remedies like Viagra, check with a pharmacist that they are sure to take with your other remedies.
