I am sorry when I check back my previous tutorial on uploading files and images, there are some mistakes that should be fixed in its database, and there are some parts that I have not explained clearly. Now I will try to explain again some of which I consider important.

1. On these tutorials you can only upload image files that have extensions gif,  jpeg and png. if you upload a file extension other than the image file, the file will not be able to upload or error.
2. create a folder image and article to store files uploaded.

download this sourcecode , demo this application

In this tutorial, I will give examples of the usage of bar chart by using extjs and php. Generally, bar chart consists of the x-axis and y-axis in this tutorial I will provide a case study about the number of sales in each month, the x-axis represents the name of the month, while the y-axis represents the total sales of each month.

we first create a database with the name of “chart” after that create a table with a “sale”, tables of contents consists of two columns of “month” and “sumOfsel”, for more details on the source code can be seen below.

CREATE TABLE IF NOT EXISTS `sale` (

 `month` int(11) NOT NULL,

 `sumOfsel` int(11) NOT NULL

) ENGINE=MyISAM  DEFAULT CHARSET=latin1;

after create tables, enter data into a table, like the example below:

INSERT INTO `penjualan` (`month`, `sumOfsel`) VALUES

(0, 1400),

(2, 2000),

(3, 4000),

(4, 8000),

(0, 30000),

(1, 5000),

(5, 14686);
