問題描述

我的問題很簡單，但我不知道如何解決.

My problem is simple, yet I can't figure out how to solve it.

我的網站是多語言的.我希望用戶能夠根據需要添加多種語言的文章，同時要求輸入他的語言(取決于他的語言環境).

My website is multilanguage. I want the user to be able to add an article in multiple language if he wants, while requiring the inputs of his language (depending on his locale).

問題是，根據 CakePHP 的翻譯約定，所有輸入都必須以字段名稱結尾，無論是什么語言.因此，所有字段對同一字段具有相同的規則.我不能要求一個名字"，而不需要另一種語言的另一個.

Problem is, with CakePHP's conventions about translation, all the inputs must end with the field's name, no matter what language. So all the fields has the same rule for the same field. I can't make one "name" required while another in another language not required.

例如，默認語言的輸入是:

For example, the default language's input would be:

<input type="text" name="name" required="required" maxlength="45" id="name">

在此之下，同一字段的另一種語言輸入:

And below that, another language's input for the same field:

<input type="text" name="locales[fr_CA][name]" required="required" maxlength="45" id="locales-fr-ca-name">

由于這些規則，required"屬性會自動添加到兩者中:

The "required" attribute is automatically added to both because of these rules:

$validator
    ->requirePresence('name', 'create')
    ->notEmpty('name')
    ->add('name', [
        'length' => [
            'rule' => ['minLength', 10],
            'message' => 'The title needs to be at least 10 characters long.',
        ]
    ]);

注意:我必須在保存時將區域設置更改為默認 (en_US) 才能保存為多種語言 + 默認語言(否則默認輸入會保存在默認表和 i18n 表中).

Note: I have to change the locale to the default (en_US) when I save to be able to save in multiple languages + the default language (otherwise the default inputs are saved in the default table AND in the i18n table).

if ($this->request->is('post')) {
    I18n::locale('en_US');
    // ......

這是我保存時的完整代碼段 (IngredientsController.php)

So here's the complete piece of code when I save (IngredientsController.php)

public function add() {
    $ingredient = $this->Ingredients->newEntity();
    if ($this->request->is('post')) {
        $ingredient = $this->Ingredients->patchEntity($ingredient, $this->request->data);

        if(isset($this->request->data['locales'])) {
            foreach ($this->request->data['locales'] as $lang => $data) {
                $ingredient->translation($lang)->set($data, ['guard' => false]);
            }
        }

        $locale = I18n::locale(); // At this point the locale is fr_CA (not de default)
        I18n::locale('en_US'); // Change the locale to the default

        if ($this->Ingredients->save($ingredient)) {
            $this->Flash->success(__('The ingredient has been saved.'));
            I18n::locale($locale); // Put the locale back to the user's locale
            return $this->redirect(['action' => 'index']);
        } else {
            I18n::locale($locale);
            $this->Flash->error(__('The ingredient could not be saved. Please, try again.'));
        }
    }

    $this->set(compact('ingredient'));
    $this->set('_serialize', ['ingredient']);
}

我設置的默認語言環境是 bootstrap.php

I set the default locale is the bootstrap.php

/**
 * Set the default locale. This controls how dates, number and currency is
 * formatted and sets the default language to use for translations.
 */
ini_set('intl.default_locale', 'en_US');
Configure::write('Config.locales', ['fr_CA']);

我在 AppController.php 中確定用戶的語言環境

I determine the user's locale in the AppController.php

public function beforeFilter(Event $event)
{
    $locales = Configure::read('Config.locales');
    $boom = explode(',', str_replace('-', '_', $_SERVER['HTTP_ACCEPT_LANGUAGE']));
    $user_lang = substr($boom[0], 0, 2);

    // This piece of code is only to change the locale to fr_CA even if the user's language is just fr or fr_FR
    if(in_array($user_lang, Configure::read('Config.langs'))) {
        if(in_array($boom[0], $locales)) {
            I18n::locale($boom[0]);
        } else {
            foreach ($locales as $locale) {
                if(substr($locale, 0, 2) == $user_lang) {
                    I18n::locale($locale);
                }
            }
        }
    }

    $this->set('locales', $locales);
    $this->set('locale', I18n::locale());
}

因此，如果我在與默認語言不同的語言環境中保存，則相同的默認輸入將保存在 fr_CA 的成分表和 i18n 表中

So if I save while being in a different locale than the default, the same default inputs will be saved in the ingredients table AND in the i18n table in fr_CA

推薦答案

默認保存在轉換表中

默認語言的輸入被存儲在翻譯表中，以防默認語言環境發生變化，這一事實似乎是預期的行為，就像讀取數據時，它將檢索關于當前語言環境，保存數據時同樣適用.

Defaults saved in translation table

The fact that the input for the default language is being stored in the translation table in case the default locale has been changed, seems to be the expected behavior, just like when reading data where it will retrieve the data with respect to the current locale, the same applies when saving data.

將區域設置更改為默認設置是一種解決方法，但它可能有點過于具有侵入性，因為它會干擾使用該值檢查當前區域設置的任何代碼.最好直接在表上設置想要的locale

Changing the locale to the default is a workaround, but it might be a little too invasive, as it will interfer with any code that uses that value to check the current locale. It's better to directly set the desired locale on the table

$Ingredients->locale(I18n::defaultLocale());

或者，這是侵入性最小的選項，改為在主實體上

or, which is the least invasive option, on the main entity instead

$ingredient->_locale = I18n::defaultLocale();

同樣，前者是鏈接文檔部分所描述的，但實際上并未顯示，需要修復.

Also the former is what the linked docs sesction is describing, but not actually showing, that needs to be fixed.

雖然我可以理解為什么表單助手(分別是實體上下文)為錯誤"字段選擇驗證規則，即 xyz.name 字段為name<選擇這些規則/code> 字段，我不知道這是否是它的工作方式.
