LET PARTY to celebrate this amazing 3.0.0 version of KoolReport. There are many more improvements in this version than any versions released before. One of the greatest enhancements is the ability to add theme to your report and work seamlessly with other PHP Frameworks.
Stunning & stunning
We are often reminded that "Don't judge a book by its cover". Why's so? Is this because we tend to look at cover first to decide whether to read a book. In other words, the book with beautiful cover naturally catches our attention and more likely they will be read by us, won't it. The same with data report. Reading a data report will be less painful and more joyful if the report looks clean and beautiful. Koolreport may not help you to create interesting content (since it may depends on your creativity) but it surely will help you to create a beautiful one so that when look at it, people want to discover your report's content.
In this version, we would like to introduce the report theming capability. A theme when applied to your report will change the way widget rendering its contents together with color and even behaviors. As a result, your report will look very much better and will impress the viewers. You will love it, your boss will love it and your clients will love it.
We have released two basic themes
Bootstrap 3 and
Bootstrap 4 however more themes will come in near future. FYI, The reports in our new demos site uses theme called Amazing which will be available soon!
class MyReport extends \koolreport\KoolReport
We understand that nowadays barely is an PHP application built without a framework. From the beginning, we designed KoolReport to work inside any PHP Frameworks like Laravel, CodeIgniter or Symfony. In this version, the integration of KoolReport into other frameworks goes to new level in which you may even use KoolReport's widgets inside those frameworks without initiating a report.
For example, you may create ColumnChart in Laravel's view file simply like this:
"dataSource" => DB::table('orders')
->select('department', DB::raw('SUM(price) as total_sales'))
->havingRaw('SUM(price) > ?', )
Do you see that ColumnChart widget is able to receive
Collection of Laravel Framework and use it as its data source. Also, the widget does not need any further settings to be rendered on Laravel's environment. KoolReport's widgets are able to work in CodeIgniter and other framework in the same ways. More information!
There are much more to say about this release but we only are able to highlight the most interesting parts here. If you are interested on more details, please read our KoolReport Version 3.0.0 Release Notes.
New Examples and Documentation
We have created a new look for our Examples and Demos. Not only new look is implemented but also 70+ more examples have been added for you to get started with.
Together with new examples, we have also upgraded our Documentation as well. We have been working very hard to write every details of the framework so that you can understand it deeper and use it better.
Enjoy & Have A Great Day!

Data storytelling will be a new exciting field in which science and art merge. And data become truly valuable only when they can drive our actions toward changes for better.
After your business has started collecting and gathering data from all sources, the next difficult step is to dig into those data and get the potential value of them. Your collected data is like a gold mine hidden deep down beneath the earth. The data analyst is like a gold miner digging into data to find valuable insights. But those insights can only become truly valuable if they can turn into actions or changes in your business. If those insights is not understood or does not look appealing to people, they are nothing more than pieces of metal. Google’s Chief Economist Dr. Hal R.Varian stated, "The ability to take data—to be able to understand it, to process it, to extract value from it, to visualize it, to communicate it—that’s going to be a hugely important skill in the next decades."
As data becomes increasingly ubiquitous, we have witnessed the hot trends of the jobs of data analysis and mining. LinkedIn recently reported that data analysis is consistently one of top 4 wanted skills in job description. But interestingly the last skill of transforming those data insights into actions is in less required although those top data analyst with advanced degrees in mathematics, economics, statistics struggle to communicate their insights to others effectively. Our ultimate goal is the change, we are getting close but still not reaching yet.
The demand of data storytelling skill will increase in the future. With the availability of self-service data tools, more and more people will be able to access the data insight by their own. As a result, more and more insights will be generated like never before. However, unless we enhanced the communication for those insights, we only see lower and lower conversion rate from insight-to-value. If people see those insight not appealing enough, change will never occurs. Data mean nothing!
Data Storytelling is a new term. Hearing the term, people normally think about the data visualization, info-graphics, dashboard, data presentation. Too often, people understand storytelling is just beautiful and clear charts and graphs. The truth is that data storytelling is a structured approach to communicate those insights, it involves combinations of three elements: data, visuals and narrative.
When we have data and narrative going along, we are explaining to our audience what is happening and maybe why. When data is coupled with visuals, we are enlightening the understanding of data. Seeing charts and graphs, we have have better feel of the trend. When visuals is applied to narratives, we are engaging our audience to the story. The effect is like we watch a good Hollywood movie. And with the combination of all three elements: data, visuals and narratives, we will explain, enlighten and engage our audiences. And by those actions, we may have the chance to drive our audiences to actions. That’s our ultimate goal.
The importance of data storytelling
Story has been going with us through the history. Our ancestors told us story of heros, our country emergence. Those story are passed from generation to generation and will be continued.
Today modern storytelling may be associated with TED for example and the analysis of the most 500 popular TED talks shows that storytelling made of 65% of their content. So we can see that storytelling is an effective way to convey ideas, thoughts and insights in the way that memorable, persuasive and engaging.
According to study, human decisions are often attached to emotion not logic. How many times we buy a thing because we want it and not because we need it? We buy a new phone to replace the last year model which is still working very well. So things that touch our emotion are the ones lead us to action. The data insights represented in numbers or charts and graphs touch us mostly in the logic layers but story touches us deeper in our emotion layers. That is the reason why story is much more effective in driving our actions by its power of memorability, persuasiveness and engagement.
Memorable: A study by Stanford professor Chip Heath (Made to Stick author) found 63% could remember stories, but only 5% could remember a single statistic. While 2.5 statistics were used on average in the exercise and only 10% of the participants incorporated a story, the stories are what caught people’s attention.
Persuasiveness: In another study, researchers tested two variations of a brochure for the Save the Children charity organization. The story-based version outperformed the info-graphic version by $2.38 to $1.14 in terms of per participant donations. Various statistics on the plight of African children were far less persuasive than the story of Rokia, a seven-year-old from Mali, Africa.
Engagement: Researchers also discovered people enter into a trance-like state, where they drop their intellectual guard and are less critical and skeptical. Rather than nitpicking over the details, the audience wants to see where the story leads them. As mathematician John Allen Paulos observed, “In listening to stories we tend to suspend disbelief in order to be entertained, whereas in evaluating statistics we generally have an opposite inclination to suspend belief in order not to be beguiled.”
Many great insights could be never be a gold if they are not fueled by a convincing story. Data storytelling will be a new exciting field in which science and art merge. And data become truly valuable only when they can drive our actions toward changes for better.

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!
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.
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 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.
Together with the new core, we have release below new package version:
- DataGrid 1.5.0: Adding formatValue for footer and enable data-search and and data-order feature.
- Pivot 4.1.0: Add count percentage and sum percentage to pivot process
- Cube 2.1.0: New
- Excel 3.0.0: Change to advanced
PHPOffice/PHPSpeadsheet library and discard the deprecated
- ChartJS 1.2.0: Return associative array on event
- SparkLines 1.20: Add ability to write js in widget creation.
- Inputs 3.5.0: Add ability to write js in widget creation.
- Morris Chart 2.0.0: Use advanced jsonEncode() function.
- DrillDown 2.0.0: Ability to work with
Beside the new version of above packages, we have add two brand new packages
- Codeigniter 1.0.0
- Laravel 1.0.0
Those two packages are free and born to make KoolReport work seamlessly in CodeIgniter and Laravel environment. In the future, we will add more packages like those two to support KoolReport working in other PHP Frameworks like Symfony, Yii2 and etc.
And not to forget, we released KoolReport Pro 2.78.0 containing all above released packages. If you own KoolReport Pro, you may upgrade now.
Have thought that the previous version was perfect, we are proved to be wrong by this new releases with a lot of enhancements. Listening to users is the key point and we will continue to do so. We thank you so much for all of your suggestions, bug reports, your case of usages that you shared with us. That's priceless! Thank you!

We are very happy to let you know that KoolReport 2.43.0 has been released. We continue to make KoolReport the great reporting framework.
It seems KoolReport core is quite stable now. Only a small change in this version compared to the previous one is the improvement for Google Chart when dealing with numeric column in string form. We were reported by one of our customers a mysterious error that broke his chart. Further investigation leaded us to the root cause. One of his column is supposed to be numeric type but stored in string form so Google Chart ran into trouble. In this version, if a column is specified type as number, we will enforce the rule by converting the value of that column to number.
Beside the new version of core, we released new package version for QueryBuilder, DataGrid, Pivot and Excel.
QueryBuilder 1.4.0 has been fixed the WHERE statement when dealing with boolean type. In addition, we fixed the issue of wrong quoting name of table and column. Now the
table.columnName will be generated correctly as
'table'.'columnName' in SQL statement.
DataGrid 1.2.0 contains improvement for
cssClass property to add custom css classes for th, tr, td, tf. We also add the
formatValue property to allow us to custom the display of column value.
Pivot 4.0.0 has biggest improvement for css. Now we can customize look n feel by overwriting its default css classes. Beside that, we added new command
expand() at client-side to expand any level we want.
Excel 1.2.0 has been added new properties
sheetIndex in ExcelDataSource to let us specify exactly what sheet of excel we want to load. This will help us to avoid problem of
Memory Limit Exceeded if we have large Excel file.
Together with above releases of new core and extended packages, we released KoolReport Pro 2.43.0 containing all recent updates. If you own KoolReport Pro license, you may update now.
