Debugging WordPress plugins on a live website

Sometimes we need to debug a WordPress plugin, even though the website is live.

This would display the errors for anyone.

1	define('WP_DEBUG', true);

Gladly WordPress provides options to do this more subtle.

// Turns WordPress debugging on

define('WP_DEBUG', true);

// Tells WordPress to log everything to the /wp-content/debug.log file

define('WP_DEBUG_LOG', true);

// Doesn't force the PHP 'display_errors' variable to be on

define('WP_DEBUG_DISPLAY', false);

// Hides errors from being displayed on-screen

@ini_set('display_errors', 0);

Enjoy coding …

Empower your website with Wolfram Alpha

Wolfram Alpha‘s computational knowledge engine or answer engine developed by Wolfram Research, which can be consumed as a service as well. Users submit queries and computation requests. Wolfram Alpha then computes answers and relevant visualizations from a knowledge base of curated, structured data that come from other sites and books. 2000 non-commercial API calls per month are free.

They provide a nice set of API Language Libraries to get you started.

<?php

$appID = 'PLACE_YOUR_APP_ID_HERE';

if (!$queryIsSet) die();

$qArgs = array();

if (isset($_REQUEST['assumption']))

$qArgs['assumption'] = $_REQUEST['assumption'];

// instantiate an engine object with your app id

$engine = new WolframAlphaEngine( $appID );

// we will construct a basic query to the api with the input 'pi'

// only the bare minimum will be used

$response = $engine->getResults( $_REQUEST['q'], $qArgs);

// getResults will send back a WAResponse object

// this object has a parsed version of the wolfram alpha response

// as well as the raw xml ($response->rawXML)

// we can check if there was an error from the response object

if ( $response->isError() ) {

<h1>There was an error in the request</h1>

</body>

</html>

<?php

die();

}

Cross browser audio/video/screen recording via webRTC – MediaStreamRecorder

MediaStreamRecorder.js is a cross-browser implementation to record audio & video streams via WebRTC. The lib allows you to submit/upload recorded blobs in realtime to your server.

Record audio+video in Chrome

var mediaConstraints = {

audio: true,

video: true

};

navigator.getUserMedia(mediaConstraints, onMediaSuccess, onMediaError);

function onMediaSuccess(stream) {

var multiStreamRecorder = new MultiStreamRecorder(stream);

multiStreamRecorder.video = yourVideoElement; // to get maximum accuracy

multiStreamRecorder.audioChannels = 1;

multiStreamRecorder.ondataavailable = function (blobs) {

// blobs.audio

// blobs.video

};

multiStreamRecorder.start(3 * 1000);

}

function onMediaError(e) {

console.error('media error', e);

}

</script>

Uploading and receiving via PHP

<?php

foreach(array('video', 'audio') as $type) {

if (isset($_FILES["${type}-blob"])) {

$fileName = $_POST["${type}-filename"];

$uploadDirectory = "uploads/$fileName";

if (!move_uploaded_file($_FILES["${type}-blob"]["tmp_name"], $uploadDirectory)) {

echo("problem moving uploaded file");

}

echo($uploadDirectory);
