Some web applications like forum or Q&A website may benefit from the list of active users displayed somewhere on the page. In this article we’ll show how to add such functionality to PHPRunner application. ASPRunnerPro/ASPRunner.NET code to follow.
We need to remember that sometimes in web application we can not determine if user is still active or left his computer or even closed his browser. What we actually going to do is to find the list of users that performed some action on the website in last 10 minutes.
We assume that login table is named users and username field is username. We are going to add one more datetime field to the login table named lastaccess.
Fairly often we want to split long forms into several steps letting users fill a few fields on each step. Besides making a long form easier to fill out for your users you can also save partial results between pages.
Here is how this can be done in PHPRunner, ASPRunnerPro and ASPRunner.NET.
Lets assume we have Cars table with about 20 fields and we want to split Add/Edit pages into three steps.
1. Create two custom views
Create two custom views (Cars1 and Cars2) based on Cars table
Most popular websites like Facebook, Twitter, Dropbox, LinkedIn etc provide an API that allows to retrieve or post data programmatically. API examples come in many programming languages and PHP is usually one of them. In this article we’ll show how easy is to add API calls to your PHPRunner project.
Lets start by adding Twitter posting functionality. We’ll be using a lightweight twitter-php library for this purpose. Similar libraries exist for other languages as well.
1. Setup a developer account with Twitter.
A quote from twitter-php usage page:
Continue Reading "Using third party API in PHPRunner apps. Playing with Twitter."Sign in to the http://twitter.com and register an application from the http://dev.twitter.com/apps page. Remember to never reveal your consumer secrets. Click on My Access Token link from the sidebar and retrieve your own access token. Now you have consumer key, consumer secret, access token and access token secret.
Date/time calculations can be perform either on database side or in your server side language (PHP, ASP, C#) or even in Javascript. We’ll try to cover all those scenarios.
When copying and pasting code from this article to your application replace table name (mytable) and field names (posted, dob).
MySQL
Calculating age
SELECT DATE_FORMAT(NOW(), '%Y') - DATE_FORMAT(dob, '%Y') - (DATE_FORMAT(NOW(), '00-%m-%d') < DATE_FORMAT(dob, '00-%m-%d')) from mytable AS age
30 days before date
select posted, DATE_SUB(posted, INTERVAL 30 DAY) from mytable
Date plus 30 days
select posted, DATE_ADD(posted, INTERVAL 30 DAY) from mytable
Difference between two dates in days
select posted, DATEDIFF(now(), posted) from mytableContinue Reading "Date/time handling in web applications"
