Doing your Qlik App Configuration in the load script, include files, or QMC (Publisher or the Qlik Repository Service APIs)?

For me, the bare minimum when it comes to app configuration in Qlik Sense or QlikView is:
– Setting paths and libs for use in data load script
– Setting “boilerplate” variables – e.g. the number/date/currency/etc formats
– Setting HidePrefix, SearchIndex and other app-specific behaviours
– Setting Product or Customer specific settings for consumption in the UI

This post adds some detail on config methods for Qlik Sense and QlikView, which fills the second tab from an earlier post about versioning.

In a multi-product/customer setup (see this previous post about deployment frameworks for context) where we follow common standards for names and folder structures we can streamline this configuration to reduce the maintenance and deployment burden.

Version sheets and tabs in the load script for Qlik Sense and QlikView

In the absence of a source control system like SVN or GIT, a quick and easy way of capturing changes in a app is to update a version control tab before passing the app back to other developers, or onto testers.

This is a very low-tech solution, but the format below works well in shared environments. The first two tabs of your application should be:
– Version (explain the app and list changes you’ve made)
– Config (set the configuration values like paths, dates, etc used in your application’s data load and UI)

Version and Config sheets will become a familiar sight

3arcade PHP game script updated to version 2.1 to work with PHP 5.6

I have an installation of the 3arcade script that’s still in the wild, and decided it was time to update it to work with PHP 5.6 (at least).

These changes fix:
– a row 0 error in play.php linked to deprecated functions
– deprecation of the ereg_replace function through use of intval
– deprecation of the mysql_connect function (and future deprecation of mysql* functions) through use of PDO
– consistency of database connection and query errors with a variable in the config file

DateTime with no DateTimeZone set in PHP.ini with ffmpeg and ClipBucket

I’ve been exploring how to generate videos on the fly through use of packages like ffmpeg (I installed this the other day), and recently tried out ClipBucket (a free video site script).

ClipBucket is a little rough around the edges, but has a load of great features, has a relatively active community, and large parts of the code are on GitHub.

Google Maps Distance (DistanceMatrix) API for UK in JSON

The postcode code has been updated to use Google’s distancematrix api, which provides a very different set of data from the old “as the bird flies” calculation (it calculates road distance, and provides transport options etc).

The following code is merely a demonstration, which can be seen here.

<?php
// Specify Postcodes to Geocode
$postcode1 = 'BH151DA';
$postcode2 = 'BH213AP';

// Set and retrieve the query URL
$request = "http://maps.googleapis.com/maps/api/distancematrix/json?origins=" . $postcode1 . "&destinations=" . $postcode2 . "&mode=driving&language=en-GB&sensor=false&units=imperial";
$distdata = file_get_contents($request);

// Put the data into an array for easy access
$distances = json_decode($distdata, true);

// Do some error checking, first for if the response is ok
$status = $distances["status"];
$row_status = $distances["rows"][0]["elements"][0]["status"];

if ($status == "OK" && $row_status == "OK") {

// Calculate the distance in miles
$distance = $distances["rows"][0]["elements"][0]["distance"]["value"];
$distance_miles = round($distance * 0.621371192/1000, 2);

echo 'The distance between '.$postcode1.' and '.$postcode2.' is '.($distance/1000).'Km ('.$distance_miles.' miles).';

} else {
    echo "Calculating the distance between your locations caused an error.";
}

?>

Having better error checking would also be a good idea if you plan to use the above code. Using &unit=imperial is optional, as Google always returns metres – so the code runs a basic calculation on these to convert to miles.

phpBB 3 Script Integration – New Threads and Replies from an External Script

This is the third article I’ve written for pulling functions in phpBB3 for external use. This one allows you to either create new posts in a forum or reply to a thread. This was created for use with a text system, where users could text in comments which would be added to a thread.

Article on phpBB3 Integration
Article on sending PM’s

I’ve put everything needed into one file as I don’t want to go through and break it up. The previous two posts (linked above) used a seperate phpbb.php file with part of the code in but this just includes everything.

<?php
// This is not set up for new thread posting, and has been config'd to not increment post count as this is for a bot.
// Further changes will be needed to clean up code as this is using external functions instead of clear documentation. --dc
define('IN_PHPBB', true);
$phpbb_root_path = (defined('PHPBB_ROOT_PATH')) ? PHPBB_ROOT_PATH : './phpBB3/';
$phpEx = substr(strrchr(__FILE__, '.'), 1);
include($phpbb_root_path . 'common.' . $phpEx);

// Start session management
$user->session_begin();
$auth->acl($user->data);
$user->setup();

// post send controller
function sendphpbbpost($pmmessage,$userid,$pmsubject) {

include_once('phpBB3/includes/functions_posting.php');
$my_subject = utf8_normalize_nfc(request_var('$pmsubject', '', true));
$message = utf8_normalize_nfc($pmmessage, '', true);
$uid = $bitfield = $options = '';
$allow_bbcode = $allow_smilies = true;
$allow_urls = true;
generate_text_for_storage($message, $uid, $bitfield, $options, $allow_bbcode, $allow_urls, $allow_smilies);
$data = array(
// General Posting Settings
'forum_id'          => 7,    // The forum ID in which the post will be placed. (int)
'topic_id'          => 5,    // Post a new topic or in an existing one? Set to 0 to create a new one, if not, specify your topic ID here instead.
'icon_id'           => false,    // The Icon ID in which the post will be displayed with on the viewforum, set to false for icon_id. (int)

// Defining Post Options
'enable_bbcode' => false, // Enable BBcode in this post. (bool)
'enable_smilies'    => true, // Enabe smilies in this post. (bool)
'enable_urls'       => false, // Enable self-parsing URL links in this post. (bool)
'enable_sig'        => true, // Enable the signature of the poster to be displayed in the post. (bool)

// Message Body
'message'           => $message,     // Your text you wish to have submitted. It should pass through generate_text_for_storage() before this. (string)
'message_md5'   => md5($message),    // The md5 hash of your message

// Values from generate_text_for_storage()
'bbcode_bitfield'   => $bitfield,    // Value created from the generate_text_for_storage() function.
'bbcode_uid'        => $uid,     // Value created from the generate_text_for_storage() function.

// Other Options
'post_edit_locked'  => 0,
'topic_title'       => $subject, // Subject/Title of the topic. (string). This is needed for new posts but for our purposes isn't.

// Email Notification Settings
'notify_set'        => false,        // (bool)
'notify'            => false,        // (bool)
'post_time'         => 0,        // Set a specific time, use 0 to let submit_post() take care of getting the proper time (int)
'forum_name'        => '',       // For identifying the name of the forum in a notification email. (string)

// Indexing
'enable_indexing'   => true,
'force_approved_state' => true, // Only runs on 6 onwards...check SUCC
);

//Now send that post...
submit_post('reply', '', '', POST_NORMAL, &$poll, &$data, $update_message = true);

}

$user->data['user_id'] = 2;    // User id of poster.
$auth->acl($user->data); // Re-initiate user after recall
$userid = $user->data['user_id'];
$pmmessage = 'This is a new reply, change this to whatever you want.';
sendphpbbpost($pmmessage,$userid,$pmsubject);

?>

Looking through the code above you will see several points that need changing. It’s currently set to ‘reply’ (change this to ‘post’ for a new post). Change all details to suit really – it’s easy to customise.

phpBB 3 Script Integration – Sending Private Messages (PM’s) From an External Script

A while back I posted an article about integrating your site to use the phpBB3 user and login system (here). When I wrote that I also used phpBB as a message system for a site; so when a user did something they were sent a private message automatically.

This bit of code (use it in conjunction with phpbb.php mentioned in the post linked to above) allows you to call a function to send a PM to any user as long as you have their ID.

<?php
// PM send controller
include_once("phpbb.php");

function sendphpbbpm($pmmessage,$userid,$pmsubject) {
include_once('forum/includes/functions_privmsgs.php');

$message = utf8_normalize_nfc($pmmessage);
$uid = $bitfield = $options = ''; // will be modified by generate_text_for_storage
$allow_bbcode = $allow_smilies = true;
$allow_urls = true;
generate_text_for_storage($message, $uid, $bitfield, $options, $allow_bbcode, $allow_urls, $allow_smilies);
$pm_data = array(
'from_user_id'        => 2,
'from_user_ip'        => "127.0.0.1",
'from_username'        => "admin",
'enable_sig'            => false,
'enable_bbcode'        => true,
'enable_smilies'        => true,
'enable_urls'        => false,
'icon_id'            => 0,
'bbcode_bitfield'    => $bitfield,
'bbcode_uid'         => $uid,
'message'            => $message,
'address_list'        => array('u' => array($userid => 'to')),
);

//Now We Have All Data Lets Send The PM!!
submit_pm('post', $pmsubject, $pm_data, false, false);
}

?>

You’ll need to modify the code above slightly to fit your needs, for example changing the admin username and user id, and then calling the function but it’s all pretty simple stuff one you’ve got all this.

To call the function (send the PM) to a fictional user 11:

<?php

$pmsubject = 'Please read this PM.';
$pmmessage = 'Thank you for reading this PM!';

$userid = '11';

sendphpbbpm($pmmessage,$userid,$pmsubject);

?>

Posting threads and replying to threads uses a similar system so I’ll put up some script for that shortly.
