我想在 Opencart 3 商店設(shè)置中將“開放”字段設(shè)置為多語言。在admin\view\template\setting\setting.twig中。我找到了這些行：<div class="form-group"> <label class="col-sm-2 control-label" for="input-open"><span data-toggle="tooltip" data-container="#tab-general" title="{{ help_open }}"> {{ entry_open }}</span></label> <div class="col-sm-10"> <textarea name="config_open" rows="5" placeholder="{{ entry_open }}" id="input-open" class="form-control">{{ config_open }}</textarea> </div></div>我從 textarea - input 和 add {% for language in languages %}、語言標(biāo)志和語言 ID 中進(jìn)行了制作。{% for language in languages %}<div class="form-group"> <label class="col-sm-2 control-label" for="input-open{{ language.language_id }}"><img src="language/{{ language.code }}/{{ language.code }}.png" title="{{ language.name }}" /><span data-toggle="tooltip" data-container="#tab-general" title="{{ help_open }}"> {{ entry_open }}</span></label> <div class="col-sm-10"> <input type="text" name="config_open[{{ language.language_id }}][title]" placeholder="{{ entry_open }}" id="input-open{{ language.language_id }}" value="{{ config_open[language.language_id] ? config_open[language.language_id].title }}" class="form-control" /> </div></div>{% endfor %}之后，在商店設(shè)置中，我有兩種語言的“開放”字段?，F(xiàn)在這些字段中的信息已被存儲(chǔ)。在前端控制器中，我做了這個(gè)。$data['open'] = nl2br($this->config->get('config_open'));什么時(shí)候一種語言都可以工作，但現(xiàn)在我有一個(gè)錯(cuò)誤：Warning: nl2br() expects parameter 1 to be string, array given in /var/www/fastuser/data/www/localstite.loc/storage/modification/catalog/controller/common/header.php on line 81

相應(yīng)的控制器文件必須包含以下代碼：
$this->load->model('localisation/language');
$languages = $this->model_localisation_language->getLanguages();
foreach ($languages as $language) {
if (isset($this->request->post[config_open' . $language['language_id']])) {
$data['config_open'][$language['language_id']] = $this->request->post['config_open' . $language['language_id']];
} else {
$data['config_open'][$language['language_id']] = $this->config->get('config_open' . $language['language_id']);
}
}
線：
<input type="text" name="config_open[{{ language.language_id }}][title]" placeholder="{{ entry_open }}" id="input-open{{ language.language_id }}" value="{{ config_open[language.language_id] ? config_open[language.language_id].title }}" class="form-control" />
用。。。來代替：
<input type="text" name="config_open{{ language.language_id }}" placeholder="{{ entry_open }}" id="input-open{{ language.language_id }}" value="{% if config_open[language.language_id] %}{{ config_open[language.language_id] }}{% endif %}" class="form-control" />
和前端線：
$data['open'] = nl2br($this->config->get('config_open'));
用。。。來代替：
$data['open'] = nl2br($this->config->get('config_open' . $this->config->get('config_language_id')));
