Some notes for symfony

View Template Shortcuts

• $sf_context: The whole context object (instance of sfContext)
• $sf_request: The request object (instance of sfRequest) 
• $sf_params: Parameters of the request 
• $sf_user: The current user session object (instance of sfUser)

Get XML information in symfony 1.4

When parse a remote xml file, I use sfWebBrowserPlugin and get the right result, like this way:

in actions code

$tar = new sfWebBrowser();
$tar->post(url_for('MsgTransfer/Recommender', true), http_build_query($this->form->getValues()));
$this->xml = $tar->getResponseXML(); 

in template code

php echo $xml->string;

then i get the error message:

Fatal error: Call to undefined method SimpleXMLElement::__toString() in /usr/share/php/symfony/escaper/sfOutputEscaperObjectDecorator.class.php on line 98

The solution to solve is use:

php echo $sf_data->getRaw('xml')->string;

PHP: How to convert ISO character (HTMLEntities) to UTF-8?

最近在寫針對 Amazon.com Bookstore 的 HTML Crawler 程式，

發現原來 Amazon.com 的網頁編碼居然不完全都是 UTF-8 編碼，

讓我抓下資料(ISO編碼)後，存不進預設編碼為 UTF-8 的資料庫，

於是乎，我向咕狗大神詢問了一番，獲得了以下的解答：

I’m facing problem in how to convert string from ISO to UTF8 previously. Due to the server configuration problem, all the UTF-8 char has been convereted into ISO (HTMLEntities) before it insert into db and those ISO character (HTMLEntities) break while showing in XML document. Now i found the solution to convert ISO character into UTF-8.

The original utf-8 chinese words: "你好"
Converted to ISO (HTMLEntities) : "& #20320;& #22909;"

For you to convert the ISO string "& #20320;& #22909;" to become utf-8 chinese words: "你好", you need to use Multibyte String function (or mbstring extension). Example below uses mb_convert_encoding function to convert ISO (HTMLEntities) characters to UTF-8.

?php $str =  "& #20320;& #22909;";
echo mb_convert_encoding($str, 'UTF-8', 'HTML-ENTITIES'); ?

FreeBSD 7.1 安裝 phpSysinfo & phpMyAdmin

phpSysInfo:

安裝：

# cd /usr/ports/www/phpsysinfo/
# make install clean

編輯設定：

# cd /usr/local/www/phpsysInfo/
# cp config.php.new config.php
# ee config.php

修改你要的設定，例如語言、預設模板等等。

接著修改 /usr/local/etc/apache22/httpd.conf：

Alias /phpsysinfo "/usr/local/www/phpsysInfo/"
<Directory "/usr/local/www/">
Options none
AllowOverride Limit
Order allow,deny
Allow from all
</Directory>

接著重開 apache 即可。

phpMyAdmin:

安裝：

# cd /usr/ports/databases/phpMyAdmin/
# make install clean

編輯設定檔：

# cd /usr/local/www/phpMyAdmin/
# cp config.sample.inc.php config.inc.php
# ee config.inc.php

在FreeBSD 7.1下，以下設定似乎可忽略 (因為我沒設定)

將 $cfg['Servers'][$i]['auth_type'] = 'cookie' ;
改為 $cfg['Servers'][$i]['auth_type'] = 'http' ;

接著修改 /usr/local/etc/apache22/httpd.conf：

Alias /phpmyadmin "/usr/local/www/phpMyAdmin/"
<Directory "/usr/local/www/">
Options none
AllowOverride Limit
Order allow,deny
Allow from all
</Directory>

如果你前面已經有加上 <Directory "/usr/local/www/">，則不需要在加上那段。

最後重開 apache 即可。

Backend Admin FileUpload for symfony 1.2

This approach is to provide a path option to sfValidatorFile...
--------------------------------------------------------------

// lib/form/StudentForm.class.php
class StudentForm extends BaseStudentForm
{
    public function configure()
    {
        $this->widgetSchema['photo'] = new sfWidgetFormInputFile();
        $this->validatorSchema['photo'] = new sfValidatorFile(array(
        'path' => sfConfig::get('sf_web_dir').'/uploads/students',
        ));
    }
}

--------------------------------------------------------------
And write a generatePhotoFilename() method on Student (assuming "Photo" is the phpName for the field name "photo")
--------------------------------------------------------------

// lib/model/Student.php
class Student extends BaseStudent
{
    public function generatePhotoFilename(sfValidatedFile $file)
    {
        return $file->getOriginalName();
    }
}

--------------------------------------------------------------

This way is probably the preferred approach as it makes for a thinner controller.
