A Must Upgraded KoolReport 2.78.0

LET PARTY to celebrate the new version of KoolReport 2.78.0. We are very proud because we thought everything was just perfect in the previous version but still this new one comes with a lot of improvements. We have been working hard to find every enhancement point even tiny. So here come the new version, all are backward compatible so you need not to worry. Please upgrade!

The core

In this version, we have reviewed all datasource classes once more time to assure they are totally safe from any security threats. Furthermore, we have improved datasources for MySQL, Postgre, SQLSRV and Oracle to reduce their response time and memory usage by enabling the connection sharing. It means that, if you have multiple queries to the same database, connection will be shared between them thus reducing the unneccessary of re-connecting time. This technique has been implemented for PdoDataSource but have not done for others.

We have improved the src($name) function as well. Previously, this method requires us to specify the name of datasource. However we found that 80% of the cases, we have only ONE datasource. So we thought that it would be nicer to just write src() without any parameter, KoolReport will automatically get the first datasource to use. A tiny improvement but it can free our mind and reduce the typo of datasource name which resulted in error.

We have also enhanced the SubReport feature. In the previous version, we use HTML comment tags to mark subreport section but we found that some web servers remove the HTML comment tags for the purpose of optimization which will cause big issue for SubReport so we change to use HTML element. As a result, SubReport now works perfectly.

In previous version of KoolReport, we may need to remove the resources folder when upgrade to new version. It is quite troublesome and easy to forget. In this version, we use KoolReport's version and widget's version as a factor to generate widget's url. It helps us to reduce the unneccessary work when upgrade library, KoolReport will make sure all generated resources files stay updated.

Another great improvement in this version is the ability to write Javascript function inside Widget creation. We have created an advanced jsonEncode() function which able to detect javascript string and later turn them into javascript function at client-side. As a result, we can write PHP and Javascript in an unified block of widget creation. Furthermore, this feature will unleash features of many widgets with heavy client-side code. Please check our case of DataGrid usage in this forum post to understand better this enhancement.

Last, we have improved the event of Google Chart and Table. Now in those events like rowClick or itemSelect, we will receive selectedRow with associate data beside the array one. For example, you can access the row id by selectedRow[0] or by selectedRow['id']. This will add convenience to get data cell value for further processing.

Above are highlights, you may view the full release note.
