mysql insert records go no error but did not succeed in mysql

Today when playing a web project, encountered such a problem, go in using the insert intocommand to insert a record, there is no error, but did not succeed in the database, at first I thought it was to obtain data post request is a problem, but more than after the test found no problems, repeatedly printing error, debug everywhere, but not always find the problem. When I post data after accidental lightly press the keyboard, even just a look successful, then I suddenly had the idea, I recently used linux, and did not consider the transcoding problem, but when you open the database in turn also go utf-8 yards, and that there is no problem, that's when I casually inserted into the mysql Chinese, I found no success, this find the problem. The next encounter this problem set about coding time to pay attention to create a table.

solve:

1. Created when transcoding

create table entries2 (
        id     int auto_increment, 
        title  text,
        content  text,
        posted_on  datetime,
        primary key (id)   
) character set = utf8;

1. Convert existing table
   alter table table_name convert to character set utf8;
