Build a guestbook with PHP_PHP tutorial

The following is the configuration description: For the convenience of configuration, the code has been rearranged. Now all the parameters that need to be set have been placed in the config.php file. It should be very simple to configure, and there are detailed instructions in it. Goal: In Get your guestbook ready within ten minutes!!! 1: Create a database (the homepage must provide database space). Generally, there is a front-end of phpMyAdmin open source. It is very simple to create. After choosing a name, remember to add config.php Change $db_name to this name 2: Create a message data table (change $table_name in config.php to the name you gave here later). The structure is: key_liuyan int(11) auto_increment primary key, //Main creation, automatic Add nikename varchar(20) null // Nickname subject varchar(100) null // Message subject date_created varchar(19) // Message time ip_address varchar(15) // Message person's IP address message mediumtext null // Message information email_address varchar (50) null // The e-mail address of the person who left the message zhuye_address varchar(50) null // The homepage address of the person who left the message huifu_biaozi int(1) default 0 // Moderator reply flag huifu mediumtext null // Moderator reply content oicq varchar (20) null // The OICQ number of the person who left the message can be completed using the following SQL!!! (I passed the test, remember to change yourtable_name to something easier to remember, of course you can leave it alone) create table your_liuyan_table( Key_liuyan int( 11) auto_increment primary key, nikename varchar(20) null, subject varchar(100) null, date_created varchar(19) , ip_address varchar(15), message mediumtext null, email_address varchar(50) null, zhuye_address varchar(50) null, huifu_biaozi int(1) default 0, huifu mediumtext null, oicq varchar(20) null ) 3: Create a control table: (Similarly put the name here in $table_name_control of config.php) The structure is as follows: leibie varchar( 20) primary key, value varchar(20) null You can also use the following SQL statement: create table your_control_table( leibie varchar(20) primary key, value varchar(20) null ) Because this is your control table, you have to add it yourself There are two control records; The SQL statement is: Insert and delete password: insert into your_control_tble( leibie, value) values ​​(delete,1332); Insert reply password: insert into your_control_tble( leibie, value) values ​​(huifu,1332); Put it in like this The password is: 123, and the user name is empty! How to calculate the relationship between the password and the inserted value? This is it, your password, such as 123, add up the three digits, equal to 6, and then multiply 6 222 is the password value!!! 6*222=1332. Knowing this relationship, of course you can change it to another password. But the user name must be empty,,, 4: After everything is completed, just add the exceptions to readme.txt Just upload the file. post.php file ＜?php require(config.php); ?＞ ＜?php $nikename=$arr_request[nikename]; if (strlen($nikename)==0) { echo "＜center ＞"; echo "＜h2＞＜font color=red＞Error message!＜/font＞＜/h2＞"; echo "Sorry, the name of ＜font color=red＞＜/font＞ must be filled in!!!
