Web applications generated by PHPRunner, ASPRunner.NET or ASPRunnerPro communicate with databases via means of SQL queries. Whenever you search, edit or delete data your web application issues a series of SQL queries, gets results back and displays it on the web page. Understanding the basics of SQL will help you build better apps and find errors faster.

Our code generators come will handy option to display all SQL queries application executes. For this purpose you can add the following line of code to AfterApplicationInitialized event:

In PHPRunner

$dDebug = true;

You need to change some field labels in your project but don't want to rebuild and upload the whole project. In this tutorial we'll show how to do that storing field labels in the database and displaying them dynamically. As a bonus we'll also show how hide fields based on visibility rules stored in the database, make fields readonly or required.

First we need to create a table in the database to store all those settings. We would need fields like table name, field name, field label and visibility. Here is the sample table script for MySQL.

CREATE TABLE `settings`(
`tablename` varchar(50) NULL, 
`field` varchar(50) NULL, `label` varchar(100) NULL, 
`visible` tinyint NULL DEFAULT 0, 
`readonly` tinyint NULL DEFAULT 0,
`required` tinyint NULL DEFAULT 0,

Some applications may require to provide users with quick editing capabilities. While Inline Edit does just that entering inline edit mode for multiple records can be painful. It would be much easier is some or all fields appear as edit controls when page is loaded.

While PHPRunner/ASPRunner.NET/ASPRunnerPro do not have such functionality built-in it's fairly easy to implement it in your project. In this sample project we'll show how to make fields ProductName, UnitPrice and Discontinued editable automatically. For now we only support text boxes and check boxes. Data is saved automatically once you leave the text box or check off check box. To see that data is actually saved in the database simply reload the page.

You can also see how server-side validation works. Enter Unit Price that is less than $20 and move to the next field to see it in action. Record won't be saved until you enter $20 or more price value.

You are no longer required to use HTML tables to arranger fields on Add/Edit/View forms. Turn on free-form mode and drag-n-drop fields and labels where they need to be. This mode is available on Add/Edit/View pages and also on List page in vertical mode.

This is an example of List page edited in free form mode.

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
