PHP/WordPress find discount

	<?php
	$deal_price = get_post_meta($post->ID, 'deal_price', true);
	$old_price = get_post_meta($post->ID, 'old_price', true);

clarklab / WP-Transient-API.php

Created January 27, 2012 21:49

Using get_transient and set_transient to save changing data

	<?php

	//let's get my klout score!!

	//first, let's see if I've got the data already cached locally
	$klout = get_transient("klout");

	//dang it! it looks like I might not. let's check with the Klout API

clarklab / wp_insert_post_front_end_form.php

Created May 25, 2012 00:12

This is a sample front-end form using wp_insert_post(). It's quickly stripped out of my production code from Android and Me, and hasn't been tested alone, so please take it with a grain of salt.

	<?

	if( 'POST' == $_SERVER['REQUEST_METHOD'] && !empty( $_POST['insert_post'] )) { //check that our form was submitted

	$title = $_POST['thread_title']; //set our title

	if ($_POST['thread_description']=="") { // check if a description was entered
	$description = "See thread title..."; // if not, use placeholder
	} else {
	$description = $_POST['thread_description']; //if so, use it

clarklab / simple_point_system.php

Created July 5, 2012 22:48

A simple point system in WordPress. I like this function almost *too much*. Please use it wisely.

	<?php

	function update_user_points($id, $value){

	$points = get_user_meta($id, 'points', true);
	$points = $points + $value;
	update_user_meta($id, 'points', $points);
	return $points;
	}

clarklab / page-redirect.php

Created July 6, 2012 03:12

Simple redirect (URL shortener / tracker) page template

	<?php
	/*
	Template Name: Redirect
	*/

	$redirect_url = get_post_meta($post->ID, 'redirect_url', true);
	// get the destination URL

	$count = get_post_meta($post->ID, 'count', true);
	// get the number of times it's been clicked

clarklab / exclude_previously_looped_posts.php

Created July 18, 2012 02:24

A simple way of making sure not to display the same posts twice when using multiple loops. Save the post ID's into an array, then exclude those posts from future loops.

	<?php

	//start a new WP_Query with whatever parameters you want
	$firstquery = new WP_Query(array(
	'posts_per_page' => 2
	'tag' => 'summer'
	));

	//start some looping action on $firstquery
	while ($firstquery->have_posts()) : $firstquery->the_post();
