codfish / search_multi_array.php
Created May 16, 2016 13:27
Search multi-dimensional array based on key value pair. i.e. you have an array of posts, and you want to return the post with the id of `1231`
<?php
$posts = [
[
'id' => 1231,
'title' => 'Test'
],
[
'id' => 1111,
'title' => 'Test #2'

Download wedding photos. Photographer put all of our photos for us and family to buy, but wasn't going to give us a digital copy. So...

exit 1

codfish / dynamic_iframe_height.js
Last active September 16, 2015 20:52

// @example
// <iframe src="/form.html" id="infographic-iframe"></iframe>
document.getElementById('infographic-iframe').style.height = $('#infographic-iframe').contents().height() + 'px';

Wordpress short links don't automatically redirect to the post permalink, like some (me) might think they should. If you switch your permalink structure to something more SEO friendly, existing posts should automatically redirect to the proper format. However, future posts will not.

codfish / regex-html-attribute.js
Last active August 29, 2015 14:24
Quick and dirty way to grab the value of an attribute from an HTML string with regex.
var html = '<iframe width="420" height="315" src="https://www.youtube.com/embed/cwhLueAWItA" frameborder="0" allowfullscreen></iframe>';
var width = html.match( /(?:.*width="(.*?)".*)?/i ).pop();
var height = html.match( /(?:.*height="(.*?)".*)?/i ).pop();
var src = html.match( /(?:.*src="(.*?)".*)?/i ).pop();

codfish / clean-multi-line-string.js
Last active August 29, 2015 14:22
Interesting way to write a multiline string in JS, to keep things clean.
var multiLiner = String() +
'<section>' +
'<div class="content-wrapper">' +
'<a href="#" class="js-link">Click Here</a>' +
'</div>' +
'</section>';
