Question

我对Drupal很新，我想创建一个自定义网格，其中包含一些可编辑的列，其他一些列则是复选框等。

我正在使用theme()函数创建表并在设置中呈现它。由于我找不到任何方法来访问表单/设置变量，在主题函数中，我在drupal数据库中创建一个包含gid值的自定义表，然后我渲染这些行。出于测试目的，我获取'变量'表行。这是迄今为止的代码：

 $form['module_settings']['profile_grid'] = array(
        '#type' => 'item',
        '#title' => t('Profile Mapping'),
        '#theme' => 'profile_mapping_grid'
    );


function theme_profile_mapping_grid($sender) {
    $header = array('', t('name'), t('value'));
    $result = db_query('SELECT v.name, v.value from {variable} v');
    while ($pair = db_fetch_object($result)) { 
        $format = array(
            '#type' => 'textfield',
            '#size' => 30,
            '#value' => $pair->name
        );
        $hhfield = array(
            '#type' => 'textfield',
            '#size' => 30,
            '#value' => $pair->value
        );
        $row = array('');
        $row[] = drupal_render($format);
        $row[] = drupal_render($hhfield);
        $rows[] = array('data' => $row);    
    }

    $output = theme('table', $header, $rows, array('id' => 'gridErrors'));
    return $output;
}

网格生成正确，但我遇到了问题。我无法在文本字段中设置'name'属性，以便稍后在提交操作上收集它的值。此外，我不确定这是否是创建设置网格的最佳方式。

任何想法，意见等都非常受欢迎。

Answer 1

您正在生成主题函数中的字段，但它不起作用，因为提交函数只会对您的表单函数生成的字段起作用。

正确的方法是生成表单函数中的所有字段（基本上是您现在在主题函数中执行的操作）并使用drupal_render在主题中呈现它们。

由于我无法找到任何方法来访问表单/设置变量，在主题函数
中

表单作为参数传递给主题函数，在你的情况下是$ sender，这就是你访问它们的方式。

这是一些未经测试的代码，但你明白了。请记住，调用$output .= drupal_render($form);非常重要，因为它会呈现Form API所需的隐藏字段，例如form_id和CSRF保护。没有这个电话，提交将无效。

function mymodule_grid_form($form_state) {
    $form = array();
    $form['variables'] = array();

    $result = db_query('SELECT v.name, v.value from {variable} v');
    while ($pair = db_fetch_object($result)) { 
        $form['variables'][$pair->name][$pair->name . '_name'] = array(
            '#type' => 'textfield',
            '#size' => 30,
            '#value' => $pair->name
        );
        $form['variables'][$pair->name][$pair->name . '_value'] = array(
            '#type' => 'textfield',
            '#size' => 30,
            '#value' => $pair->value
        );
    }

    return $form;
}

function theme_mymodule_grid_form($form) {
    $header = array('', t('name'), t('value'));

    foreach ($form['variables'] as $variable => $values) {
        $row = array('');
        $row[] = drupal_render($values[$variable . '_name']);
        $row[] = drupal_render($values[$variable . '_value']);
        $rows[] = array('data' => $row); 
    }

    $output = theme('table', $header, $rows, array('id' => 'gridErrors'));
    $output .= drupal_render($form);
    return $output;
}

function mymodule_theme() {
  return array(
    'mymodule_grid_form' => array(
      'arguments' => array('form' => NULL),
    ),
  );
}

根据Drupal 6 Form API Quickstart Guide：

不要对用户可以更改的任何表单元素使用'#value'属性。请改用“#default_value”属性。不要把$ form_state ['values']（或$ _POST）的值放在这里！ FormsAPI将为您处理;只把这个字段的原始值放在这里。

您必须使用'#default_value' => $pair->name而不是'#value' => $pair->value。

以下是带有设置表的示例模块。

安装文件：

<?php
// $Id$

/**
 * @file
 * The your_module module install file, which handles the install/uninstall tasks.
 *
 */

function your_module_install() {
  // Create tables.
  drupal_install_schema('your_module');
}

/**
 * Implementation of hook_schema().
 */
function your_module_schema() {

/* Settings table */
$schema['your_module_settings'] = array(
    'description' => 'Stores module settings.',
    'fields' => array(
        'record_id' => array(
            'description' => 'The primary identifier for a record.',
            'type' => 'serial', 
            'unsigned' => TRUE, 
            'not null' => TRUE),
        'item_code' => array(
