PHP and JavaScript processing of Multiple Choices

PHP and JavaScript are used to process multiple choices. When reading how PHP and JavaScript process multiple choices, we often need to make multiple choices for users, for example, you can select multiple items in the list and then delete the selected items. Today, we will give an example to illustrate how PHP and JavaScript process multiple choices. Today we are working on a voting system, for MyS "> <LINKhref =" htt

We often need to make multiple choices for users, such as allowing users to select multiple items in the list and delete the selected items. Today, we will give an example to illustrate how PHP and JavaScript process multiple choices. Today, we are working on a voting system to vote for items in the itemtable table of the MySQL database, and each individual IP Address can only vote for two votes.

 
The itemtable is created using the following MySQL statement:

Create table 'itemtable '(
'Id' TINYINT (4) not null AUTO_INCREMENT,
'Name' VARCHAR (50) not null,
'Votes 'SMALLINT (6) not null,
Primary key ('id ')
);

The field "name" is the name of the list project, and "votes" is the number of votes. We also need to create a table "voteiptable" to record the IP address of the voting User:

Create table 'voteiptable '(
'Id' SMALLINT (6) not null,
'Voteip' VARCHAR (15) not null,
Primary key ('id ')
);

Next we will write the file "multivote. php". Today we will use a database file "dbclass. php ".

We can find that the JavaScript on the client and PHP on the server have many similarities and differences in processing multiple choices. This is a classic multi-option processing program, which is simpler if user options are not limited.
