The first step: upload the original image file
Private Function Uploadavatar ($uid) {
Check the validity of uploaded files

}
Local temporary storage location

If the temporarily stored folder does not exist, create it first
$dir =dirname ($tmpPath);
if (!file_exists ($dir)) {
@mkdir ($dir, 0777, true);
}
If a temporary file with the same name already exists, delete it first
if (file_exists ($tmpPath)) {
@unlink ($tmpPath);
}
Save the uploaded picture file to a predetermined location
if (@copy ($_files[' filedata '] [' tmp_name '], $tmpPath) | | @move_uploaded_file ($_files[' filedata '] [' Tmp_name '], $ Tmppath)) {
@unlink ($_files[' filedata '] [' tmp_name ']);

Return-2; Invalid photograph!
}
} else {

return-4; Can not write to the data/tmp folder!
} //the URL used to access the temporary picture file

} Step two: Upload the split three image data stream
Private Function Rectavatar ($uid) {
Extract three image streams from $_post
$bigavatar = $this->flashdata_decode ($_post[' avatar1 '));
$middleavatar = $this->flashdata_decode ($_post[' avatar2 '));

}
Directory is not present, create

} Save as Picture file

$success = 0;
}
Delete a temporary stored picture
$tmpPath = $this->temppath. " {$uid}.jpg ";
@unlink ($tmpPath);
Temporary Save Avatar
$con =mysql_connect (' localhost ', ' root ', ' root ');
mysql_select_db (' Zenyue ');
mysql_query ("Set names UTF8");
$sql = "Update zen_user set ' face ' = '". $uid. "' Where mid= '". $this->mid. "'";
mysql_query ($sql);
Return ' <?xml version= "1.0"? ><root><face success= "'. $success. '/></root> ';
}
Access to the URL of the avatar picture from the client
Public Function Getavatarurl ($uid, $size = ' middle ') {
$ci = &get_instance ();
$user _info = $ci->session->userdata (' User_info ');
return $this->viewpath. " {$user _info[' mid ']}/{$uid}_{$size}.jpg ";
}
Handling HTTP Request
Return value: If it is an identifiable request, returns true after processing, or false.
Public Function ProcessRequest () {
To disassemble a custom parameter from the input parameter
$arr = Array ();
PARSE_STR ($_get[' input '), $arr);
$uid = $arr [' uid '];
if ($_get[' a '] = = ' Uploadavatar ') {
The first step: upload the original image file
echo $this->uploadavatar ($UID);
return true;
else if ($_get[' a '] = = ' Rectavatar ') {
Step two: Upload the split three image data stream
echo $this->rectavatar ($UID);
return true;
}
return false;
}
Edit the HTML code in the page that contains camera.swf
Public Function renderhtml ($uid) {
Assemble the custom parameters that need to be returned in the input
$ci = &get_instance ();
$user _info = $ci->session->userdata (' User_info ');
$input = UrlEncode ("uid={$uid}&fsessionid=". session_id (). ' &mid= '. $user _info[' mid ']);
$BASEURL = '/public/zen/js/avatar/';
$uc _api = UrlEncode ($this->urlpath. ' avatar.php ');
$urlCameraFlash = "{$baseUrl}camera.swf?m=user&inajax=1&appid=1&ucapi={$uc _api}&input={$input} &uploadsize=2048 ";
$urlCameraFlash = ' <script src= '. $baseUrl.
