AJAX请求下$phrases数组转为字符串的问题修复求助

我在通过AJAX请求获取数据并使用$phrases数组进行文本翻译时遇到问题：

• 非AJAX场景下，var_dump($phrases)显示为正常数组（包含3140个元素的翻译数组）
• 但AJAX请求进入subcategory方法后，var_dump($phrases)显示为字符串"home"，导致翻译功能失效

$phrases原本是从控制器index()方法传入subcategory($phrases)的，请求修复该问题。

正常场景下的$phrases示例 #

array(3140) { 
  ["absolutely"]=> string(23) "बिल्कुल" 
  ["achieve"]=> string(58) "प्राप्त करना" 
}

控制器代码 #

class Lispo extends BaseController {
    public function index() {
        $commonData = $this->getCommonData();

       //<<>>[[ Access the $phrase and $selectedLanguage variable from the common data  ]]<<>>//
       $phrases = $commonData['phrase'];
  
       $this->subcategory($phrases);

}//other code here


  public function subcategory($phrases) {
               
               if (isset($_POST['csrf_token']) && CSRFHelper::verifyCsrfToken($_POST['csrf_token'])) {
                   require_once 'app/models/category.class.php';
                   require_once 'app/libs/cryptor.class.php';
                   $crypt = new Cryptor();
                   $categoryModel = new Category();
                   $translator = new TextTranslator($phrases);
                   $id = trim($_POST['dataId']);
                   $results = $categoryModel->getCategoriesWithSubcategories($id);
                   $html = '';
              
                   foreach ($results as $subcategory) {
                       // Add condition for status 0
                       $statusClass = ($subcategory->status == 0) ? 'fa-solid fa-lock' : 'bi bi-chevron-right';
                       $disableClass = ($subcategory->status == 0) ? 'disable-click' : '';
                       $subid = $crypt->encryptId($subcategory->catID);
                       $subcategoryName = $translator->translateText($subcategory->category);
                       $html .= '<div class="s_cali s_vrEfW5 ' . $disableClass . '" role="button" data-id="' . $subid . '"><span class="s_evrEOf">' . $subcategoryName . '</span><span class="' . $statusClass . '"></span></div>';
                   }
           
                   // Instead of echo json_encode($html);
                   echo json_encode(['success' => true, 'html' => $html]);
               }
             
           }
    }

AJAX请求代码 #

$(document).on("click", ".s_zpSpH4", function (e) {
  e.preventDefault();
  var csrf_token = $(".csrf_token").val();
  var dataId = $(this).data("id");

  var clickedElement = $(this);  // Store the reference to the clicked element

  $.ajax({
    type: "POST",
    url: BASEURL + "lispo/subcategory",
    data: { csrf_token: csrf_token, dataId: dataId },
    dataType: "json",
    success: function (data) {
      console.log(data);
      if (data.success) {
        clickedElement.hide();  // Use the stored reference to hide the clicked element
        $('.s_qeV3Mr').html(data.html);
      } else {
        console.log(data.error);
      }
    },
    error: function (error) {
      // Handle errors if any
      console.error("AJAX error:", error);
      console.log(error.responseText);
    },
  });
});

问题根源：AJAX请求是直接访问lispo/subcategory独立路由，框架会直接调用subcategory方法，而非通过index方法调用，导致$phrases参数没有传入正确数组，反而被路由系统默认值填充为字符串"home"。

具体修改步骤 #

1. 修改subcategory方法，让它自行获取$phrases

public function subcategory() {
    // 直接在方法内获取翻译数组，和index方法逻辑一致
    $commonData = $this->getCommonData();
    $phrases = $commonData['phrase'];
               
    if (isset($_POST['csrf_token']) && CSRFHelper::verifyCsrfToken($_POST['csrf_token'])) {
        require_once 'app/models/category.class.php';
        require_once 'app/libs/cryptor.class.php';
        $crypt = new Cryptor();
        $categoryModel = new Category();
        $translator = new TextTranslator($phrases);
        $id = trim($_POST['dataId']);
        $results = $categoryModel->getCategoriesWithSubcategories($id);
        $html = '';
      
        foreach ($results as $subcategory) {
            // Add condition for status 0
            $statusClass = ($subcategory->status == 0) ? 'fa-solid fa-lock' : 'bi bi-chevron-right';
            $disableClass = ($subcategory->status == 0) ? 'disable-click' : '';
            $subid = $crypt->encryptId($subcategory->catID);
            $subcategoryName = $translator->translateText($subcategory->category);
            $html .= '<div class="s_cali s_vrEfW5 ' . $disableClass . '" role="button" data-id="' . $subid . '"><span class="s_evrEOf">' . $subcategoryName . '</span><span class="' . $statusClass . '"></span></div>';
        }

        echo json_encode(['success' => true, 'html' => $html]);
    }
}

2. 修改index方法中调用subcategory的逻辑

public function index() {
    $commonData = $this->getCommonData();
    $phrases = $commonData['phrase'];
  
    // 无需再传递$phrases参数
    $this->subcategory();
}

修改后，无论是index方法调用还是AJAX直接请求，subcategory都能正确获取完整的$phrases数组，翻译功能即可正常工作。
