在Ajax调用期间，TYPO3 Flexform设置不可用

Question

对于我的TYPO3 Extbase扩展，我想做一些分页。到目前为止，ajax调用和其他一切都很好。但是当我在ajax调用期间尝试访问$this->settings数组时，存储了flexform前端插件值，我总是得到null。该部分看起来像这样：

$limit = $this->settings['result']['amount'];
$orderType = $this->settings['order']['type'];
$orderFields = $this->settings['additionorder']['fields'];

$formArr = array();
$this->request->hasArgument('offset') ? $offset = $this->request->getArgument('offset') : null;
$forms = $this->formRepository->findFormsChunked(
$orderFields, $orderType, $limit, $offset
);

foreach ($forms as $key => $form) {
         $formArr[] = array(
                    'formUid' => $form->getUid(),
                    'formName' => $form->getName(),
                    'formFile' => $form->getFile()->getOriginalResource()->getPublicUrl(),
                    'formType' => $form->getFormtype()->getUid()
                );
            }
 return json_encode($formArr);

在我的ajax调用期间，

$ this-＆gt;设置为空，但我无法想象为什么。值是否仅在渲染过程中可用，这在ajax调用期间不会发生？

感谢您的帮助。

更新

据我所知，flexform值只传递给选定的控制器动作（即displaycond），如下所示：

 <displayCond>FIELD:switchableControllerActions:=:Controller->ajax:AND:FIELD:switchableControllerActions:=:Controller->normal</displayCond>

并在选择菜单中：

                               <numIndex index="1">
                                    <numIndex index="0">LLL:EXT:ext_formpool/Resources/Private/Language/locallang.xlf:name</numIndex>
                                    <numIndex index="1">Controller->normal;Controller->ajax</numIndex>
                                </numIndex>

那么值也应该传递给ajaxAction吗？目前它们不可用......

解决方案

不幸的是，如果你使用单独的页面类型进行ajax调用，它根本不起作用。 flexform存储在数据库中，仅在框架加载过程中进行解析。您可以通过包含配置管理器来检查这一点，并尝试解析内容对象＆＃34; pi_flexform＆＃34;领域。或者您注入了flexformservice，它在ajax调用期间也未加载。您必须使用eID机制来实现此目的。

为什么不，而不是将您的插件呈现为内容对象，直接在您的ajax调用中解决它？

plugin_yourext_ajax = PAGE
plugin_yourext_ajax {
    typeNum = 2000

    config {
        disableAllHeaderCode = 1
        xhtml_cleaning = 1
        admPanel = 0
        additionalHeaders = Content-type: text/plain
        no_cache = 1
    }

    10 = USER
    10 {
        userFunc = TYPO3\CMS\Extbase\Core\Bootstrap->run
        pluginName = YourPLugin
        extensionName = YourExt
        controller = ControllerName
        vendorName = Vendor
        action = ajax

        switchableControllerActions {
            YourPlugin {
                1 = ajax
            }
        }

        persistence =< plugin.tx_your_ext.persistence
        view =< plugin.tx_your_ext.view
        update =< plugin.tx_your_ext.update
        settings < plugin.tx_your_ext.settings
    }
}

我也有这个问题，比我发现你需要使用renderObj，它将使用ContentObjectRenderer类。我需要从我的列表模板f：链接到详细信息页面的Flexform值。

所以在我的情况下，我也想要Ajax分页。我只是在我自己的新闻扩展的列表视图中使用了默认的Fluid paginate小部件。如果客户端没有javascript它仍然可以工作。因此，创建很酷的Ajax分页真的很容易！

typeNum的Typoscript：

              $('body').on('click', 'div.jpnews-list ul.f3-widget-paginator li a', (function (e) {
                    e.preventDefault();
                    paginateToPageURI = $(this).attr('href') + '&type=' + TYPO3pageType;
                    var parentDivOfNewsList = $(txJpNews).parent();
                    $(txJpNews).css('opacity', 0.4);
                    $(parentDivOfNewsList).append(spinnerHTML);
                    $.ajax({
                        type: 'POST',
                        url: paginateToPageURI,
                        data: $(this).serializeArray(),
                        success: function (data) {
                            $(parentDivOfNewsList).html(data);
                        },
                        error: function (xhr, thrownError) {
                            var msg = "<b>Sorry but there was an error, please contact us..</b><br>";
                            $(parentDivOfNewsList).html(msg + xhr.status + ' ' + thrownError);
                        }
                    });
                })

可能的javascript的一部分：

require 'torch'
require 'nn'
require 'cudnn'
require 'cunn'
require 'cutorch'
require 'nngraph'

data1 = torch.ones(4,20):cuda()
data2 = torch.ones(4,10):cuda()

tmodel = nn.Sequential()
tmodel:add(nn.Linear(20,10))
tmodel:add(nn.Linear(10,10))
parallelModel = nn.ParallelTable()
parallelModel:add(tmodel)
parallelModel:add(nn.Identity())
parallelModel:add(nn.Identity())

model = parallelModel
if true then
  local function sharingKey(m)
     local key = torch.type(m)
     if m.__shareGradInputKey then
        key = key .. ':' .. m.__shareGradInputKey
     end
     return key
  end

  -- Share gradInput for memory efficient backprop
  local cache = {}
  model:apply(function(m)
     local moduleType = torch.type(m)
     if torch.isTensor(m.gradInput) and moduleType ~= 'nn.ConcatTable' then
        local key = sharingKey(m)
        if cache[key] == nil then
           cache[key] = torch.CudaStorage(1)
        end
        m.gradInput = torch.CudaTensor(cache[key], 1, 0)
     end
  end)
end

if true then
  cudnn.fastest = true
  cudnn.benchmark = true

  -- Wrap the model with DataParallelTable, if using more than one GPU
  local gpus = torch.range(1, 2):totable()
  local fastest, benchmark = cudnn.fastest, cudnn.benchmark

  local dpt = nn.DataParallelTable(1, true, true)
     :add(model, gpus)
     :threads(function()
        local cudnn = require 'cudnn'
        cudnn.fastest, cudnn.benchmark = fastest, benchmark
     end)
  dpt.gradInput = nil

  model = dpt:cuda()
end


newmodel = nn.Sequential()
newmodel:add(model)

input1 = nn.Identity()()
input2 = nn.Identity()()
input3 = nn.Identity()()

out = newmodel({input1,input2,input3})

r1 = nn.NarrowTable(1,2)(out)
r2 = nn.NarrowTable(2,2)(out)

f1 = nn.JoinTable(2)(r1)
f2 = nn.JoinTable(2)(r2)

n1 = nn.Sequential()
n1:add(nn.Linear(20,5))

n2 = nn.Sequential()
n2:add(nn.Linear(20,5))  

f11 = n1(f1)
f12 = n2(f2)

foutput = nn.JoinTable(2)({f11,f12})

g = nn.gModule({input1,input2,input3},{foutput})
g = g:cuda()


g:forward({data1, data2, data2})
g:backward({data1, data2, data2}, torch.rand(4,10):cuda())

我们通过将插件的uid（内容元素）添加到Ajax请求的URL，然后使用FlexFormService加载flexform配置来解决了这个问题。

在Controller中构建URL：

$url = $this->uriBuilder->setTargetPageType(1234)->uriFor(
    'ajaxAction',
    [
        'contentUid' => (int) $this->configurationManager->getContentObject()->data['uid']
    ]
);

通过设置弹性格式设置来初始化Controller操作：

class SomeController extends \TYPO3\CMS\Extbase\Mvc\Controller\ActionController
{
    protected $flexFormService;
    protected $flexformSettings = [];

    public function injectFlexFormService(\TYPO3\CMS\Extbase\Service\FlexFormService $flexFormService): void
    {
        $this->flexFormService = $flexFormService;
    }

    public function initializeAction(): void
    {
        parent::initializeAction();

        if ($this->request->hasArgument('contentUid')) {
            $recordUid = (int) $this->request->getArgument('contentUid');
            $record = TYPO3\CMS\Backend\Utility\BackendUtility::getRecord('tt_content', $recordUid, 'pi_flexform');

            if (!empty($record['pi_flexform'])) {
                $this->flexformSettings = $this->flexFormService->convertFlexFormContentToArray($record['pi_flexform']);
            }
        }
    }

    public function ajaxAction(): void
    {
        //access $this->flexformSettings;
    }
}

您是否在ext_tables.php声明了您的柔印？我通常这样做：

$extensionName = t3lib_div::underscoredToUpperCamelCase($_EXTKEY);
$pluginNames = array('pluginname1','pluginname2','...');

foreach ($pluginNames as $pluginName) {
    $pluginSignature = strtolower($extensionName) . '_'.$pluginName;

    $GLOBALS['TCA']['tt_content']['types']['list']['subtypes_excludelist'][$pluginSignature] = 'recursive';
    $GLOBALS['TCA']['tt_content']['types']['list']['subtypes_addlist'][$pluginSignature] = 'pi_flexform';
    t3lib_extMgm::addPiFlexFormValue($pluginSignature, 'FILE:EXT:' . $_EXTKEY . '/Configuration/FlexForms/'.$pluginName.'.xml');
}
