我的主要问题是：

每当通过 ahah (ahah_helper) 重建表单时，是否会调用 theme_hook() 函数？

我试图显示一个带有一些过滤选项的选择框，当用户更改它时，它下面的表格也会发生变化。

我现在有这个：

function veiculos_listar_form($form_state)
{
    $form = array();
    ahah_helper_register($form, $form_state);

    //biulds $options

    $form['listar_veics'] = array(
        '#type'   => 'fieldset',
        '#prefix' => '<div id="listar-veics-wrapper">', 
        '#suffix' => '</div>',
        '#tree'   => TRUE,
        );


    if (!isset($form_state['values']['listar_veics']['filial']))
        $form['#filial_veic'] = 1;
    else 
        $form['#filial_veic'] = $form_state['values']['listar_veics']['filial'];

    $form['listar_veics']['filial'] = array(
        '#type' => 'select', 
        '#title' => "Listar veículos da filial", 
        '#options' => $filiais,
        '#default_value' => $form['#filial_veic'],
        '#ahah' => array(
            'event'     => 'change',
            'path'      => ahah_helper_path(array('listar_veics')),
            'wrapper'   => 'listar-veics-wrapper',
            'method'    => 'replace',
            ),
    );


    return $form;
} 

function veiculos_listar_form_submit($form, &$form_state)
{

}


function _listar_veiculos_tabela($filial)
{
    //builds $header and $data

    $table = theme_table($header, $data);
    return $table;
}


function theme_veiculos_listar_form($form) 
{
    $output = drupal_render($form);
    $filial = $form['#filial_veic'];
    $output .= '<br>' . $filial . '<br>';
    $output .= _listar_veiculos_tabela($filial);
    return $output;
}

function veiculos_theme() {
    return array(
        'veiculos_listar_form' => array(
            'arguments' => array('form' => NULL),),
    );
}

在我的小天真的世界里，如果在每个 ahah 事件（更改）上都调用了 theme_hook，它应该可以工作。

问题是，打印的变量总是相同的，就像用户选择的内容没有被存储一样。如果用户选择不同的选项，它会显示新选项，但在主题打印时 $filial 变量始终相同。

像这样：

关于我可以做些什么来完成这项工作的任何建议？我正在开发我们自己的模块，所以使用视图模块不是一个好主意。

谢谢。

您应该以这种方式重做代码。啊啊回调我没写，我想你不会有问题的。查看 drupal.org 上的一些示例

function veiculos_listar_form($form_state)
{
    $form = array();
    ahah_helper_register($form, $form_state);

    //biulds $options

 // remove divs because we do not want to reload selector with ahah
    $form['listar_veics'] = array(
        '#type'   => 'fieldset',
        '#tree'   => TRUE,
    );


    if (!isset($form_state['values']['listar_veics']['filial']))
        $form['#filial_veic'] = 1;
    else 
        $form['#filial_veic'] = $form_state['values']['listar_veics']['filial'];

  // add cover div here, because we will reload table
    $form['table'] = array(
        '#prefix' => '<div id="listar-veics-wrapper">', 
        '#suffix' => '</div>',
        '#type' => 'markup',
        '#value' => _listar_veiculos_tabela($form['#filial_veic']),
    );

    $form['listar_veics']['filial'] = array(
        '#type' => 'select', 
        '#title' => "Listar veículos da filial", 
        '#options' => $filiais,
        '#default_value' => $form['#filial_veic'],
        '#ahah' => array(
            'event'     => 'change',
            'path'      => ahah_helper_path(array('listar_veics')),
            'wrapper'   => 'listar-veics-wrapper',
            'method'    => 'replace',
            ),
    );


    return $form;
} 

function veiculos_listar_form_submit($form, &$form_state)
{

}


function _listar_veiculos_tabela($filial)
{
    //builds $header and $data

    $table = theme_table($header, $data);
    return $table;
}


function theme_veiculos_listar_form($form) 
{
    $output = drupal_render($form);
    return $output;
}

function veiculos_theme() {
    return array(
        'veiculos_listar_form' => array(
            'arguments' => array('form' => NULL),),
    );
}
