Question

我在我的项目中使用PHPTAL几乎所有情况都能成功实现它，除非我想使用它的i18n服务。我不断收到错误“调用非对象上的成员函数”

我曾尝试搜索网络论坛等但未找到任何解决方案，如果有人可以帮助我，我将非常感激。

令人沮丧的是，没有人回答我的问题，所以我终于找到了解决方案并回答了我自己的问题。

默认情况下，PHPTAL没有设置翻译器，以便将文本从一种语言翻译成另一种语言。所以你要自己做。下面有一些步骤可以做到这一点。。

步骤1。创建一个新的php文件（例如 MyTranslator.php ）并生成一个新类，例如 PHPTAL_MyTranslator 并将其存储在里面PHPTAL文件夹。该类将实现接口 PHPTAL_TranslationService 。这个界面有五个功能，但我们关注的功能只是 translate 。因此，只需为其余函数添加声明，并为translate函数编写代码。我在我的案例中编写和使用的课程是：

class PHPTAL_MyTranslator implements PHPTAL_TranslationService {

    /**
     * current execution context
     */
    protected $_context = null;

    /**
     * @param string (name of the language)
     * @return string (language you've just set)
     *
     * This method sets translation language.
     * Name of the language is a dir name where you keep your translation files
     */
    public function setLanguage() {
    }

    public function __construct( $context ) {
        $this->_context = $context;
    }

    /**
     * @param string (translation file name)
     * @return void
     *
     * You can separate translations in several files, and use only when needed.
     * Use this method to specify witch translation file you want to
     * use for current controller.
     */
    public function useDomain( $domain ) {
    }

    /**
     * Set an interpolation var.
     * Replace all ${key}s with values in translated strings.
     */
    public function setVar( $key, $value ) {
    }

    /**
     * Translate a text and interpolate variables.
     */
    public function translate( $key, $htmlescape=true ) {
        $value = $key;
        if( empty( $value ) ) {
            return $key;
        }
        while( preg_match( '/\${(.*?)\}/sm', $value, $m ) ) {
            list( $src, $var ) = $m;
            if( !array_key_exists( $var, $this->_context ) ) {
                $err = sprintf( 'Interpolation error, var "%s" not set', $var );
                throw new Exception( $err );
            }
            $value = str_replace( $src, $this->_context->$var, $value );
        }
        return gettext( $value );
    }

    /**
     * Not implemented yet, default encoding is used
     */
    public function setEncoding( $encoding ) {
    }
}

class PHPTAL_MyTranslator implements PHPTAL_TranslationService {

    /**
     * current execution context
     */
    protected $_context = null;

    /**
     * @param string (name of the language)
     * @return string (language you've just set)
     *
     * This method sets translation language.
     * Name of the language is a dir name where you keep your translation files
     */
    public function setLanguage() {
    }

    public function __construct( $context ) {
        $this->_context = $context;
    }

    /**
     * @param string (translation file name)
     * @return void
     *
     * You can separate translations in several files, and use only when needed.
     * Use this method to specify witch translation file you want to
     * use for current controller.
     */
    public function useDomain( $domain ) {
    }

    /**
     * Set an interpolation var.
     * Replace all ${key}s with values in translated strings.
     */
    public function setVar( $key, $value ) {
    }

    /**
     * Translate a text and interpolate variables.
     */
    public function translate( $key, $htmlescape=true ) {
        $value = $key;
        if( empty( $value ) ) {
            return $key;
        }
        while( preg_match( '/\${(.*?)\}/sm', $value, $m ) ) {
            list( $src, $var ) = $m;
            if( !array_key_exists( $var, $this->_context ) ) {
                $err = sprintf( 'Interpolation error, var "%s" not set', $var );
                throw new Exception( $err );
            }
            $value = str_replace( $src, $this->_context->$var, $value );
        }
        return gettext( $value );
    }

    /**
     * Not implemented yet, default encoding is used
     */
    public function setEncoding( $encoding ) {
    }
}

第2步。现在打开 PHPTAL.php 文件并修改 PHPTAL 类的构造函数。在此功能中添加一行，如下所示。。。。

之前

public function __construct($path=false)
{
    $this->_path = $path;
    $this->_globalContext = new StdClass();
    $this->_context = new PHPTAL_Context();
    $this->_context->setGlobal($this->_globalContext);

    if (function_exists('sys_get_temp_dir')) {
    ............

public function __construct($path=false) { $this->_path = $path; $this->_globalContext = new StdClass(); $this->_context = new PHPTAL_Context(); $this->_context->setGlobal($this->_globalContext); if (function_exists('sys_get_temp_dir')) { ............

后

public function __construct($path=false) { $this->_path = $path; $this->_globalContext = new StdClass(); $this->_context = new PHPTAL_Context(); $this->_context->setGlobal($this->_globalContext); //Set translator here $this->setTranslator( new PHPTAL_MyTranslator( $this->_context ) ); if (function_exists('sys_get_temp_dir')) { .............

这两个简单的步骤将使您的 i18n：attributes 以及 i18n：translate 属性正常工作。

干杯...
