i’m a portuguese student and i’m trying to implement a web application for game’s management.
structure for table game
game (
idGame int(11) NOT NULL AUTO_INCREMENT,
name varchar(75) NOT NULL,
primaryScreen blob NOT NULL,
game_content blob NOT NULL,
category varchar(45) NOT NULL,
platform varchar(45) NOT NULL,
device varchar(45) NOT NULL,
description varchar(250) NOT NULL,
funcionalities varchar(150) NOT NULL,
PRIMARY KEY (idGame)
)
screen (
idScreen int(11) NOT NULL AUTO_INCREMENT,
id_Game int(11) NOT NULL,
image longblob NOT NULL,
PRIMARY KEY (idScreen),
KEY id_Game (id_Game)
)
i have read a yii tutorial of how to upload a file to a bolb in a database http://www.yiiframework.com/wiki/95/saving-files-to-a-blob-field-in-the-database
the only diference is that in the function before save i only want to keep the content of file (can i do this or do i have to keep file name, file extension…) so i do like this in model:
public function beforeSave()
{
if($file=CUploadedFile::getInstance($this,‘game_uploaded’))
{
// $this->file_name=$file->name;
//$this->file_type=$file->type;
//$this->file_size=$file->size;
$this->game_content=file_get_contents($file->tempName);
//$file->saveAs(‘path/to/uploads’);
}
if($file=CUploadedFile::getInstance($this,‘primscreen’))
{
//$this->file_name=$file->name;
//$this->file_type=$file->type;
//$this->file_size=$file->size;
$this->primaryScreen=file_get_contents($file->tempName);
//$file->saveAs(‘path/to/uploads’);
}
return parent::beforeSave();
}
but when i try i have this error:
PDOStatement::execute(): MySQL server has gone away
could someone help me please? i appreciate any sugestion. thanks
