我需要将自定义组件过滤器表单从组件视图移动到模块。
在模块I中，从xml：

我抓住已发布的变量并将其置于州：
$form = &JForm::getInstance('myform', JPATH_ROOT.'/components/com_man/models/forms/filter_oferty.xml');
我用：
if ($filters = $app->getUserStateFromRequest('com_man.oferty.filter', 'filter', array(), 'array'))
foreach ($filters as $name => $value) $app->setUserState('filter.' . $name, $value);
在模块中放置字段，表单有效，但我无法在请求后自动填写表单中的已发布变量。我错过了什么？ Joomla如何设定这些价值观？
答案 0 :(得分：0)
如果有人需要，我找到了在模块中制作简单表格的解决方案：
加载表单xml：
$form = &JForm::getInstance('myform', JPATH_ROOT.'/components/com_man/models/forms/filter_oferty.xml');
将字段放在html中：
<?php echo $form->getInput('search', 'filter',$filters['search']); ?>
第三个参数是默认视图。不需要使用状态。
