Question

我正在使用Drupal 7中的hook_form_FORM_ID_alter来创建自定义表单，以便用户可以输入和编辑数据，然后将数据附加到自定义节点类型。

对于一个新节点，组中默认的输入框数为10，然后可以将其添加到5个组中。当重新加载节点进行编辑时，保存的数据用于创建任意数量的表单。之前已保存输入，并且还能够以所需的相同方式添加更多字段。

我已经设法使用以下代码同时获得表单的初始版本和编辑版本，但是当按下“add five”按钮并调用AJAX（在两种情况下）时，任何值都已经输入而不保存将被删除。

<?php 

/**
 * Implements hook_form_FORM_ID_alter().
 */

function entries_form_form_entries_node_form_alter(&$form, &$form_state, $form_id) {


$node = $form['#node'];
// fieldset
$form["section"] = array(
    '#type' => 'fieldset',
    '#title'=> 'Section 1',     
);
$form["section"]["termwrapper"] = array(
    "#type" => 'container',
    "#attributes" => array(
        "id" => 'groupWrapper',
    ),
);
$form["section"]["termwrapper"]["terms"]["#tree"] = TRUE;
if(!isset($form_state['fired'])){
    $form_state['terms'] = $node->entries_form['term'];
}

foreach ($form_state['terms'] as $key => $values) {
    $form["section"]["termwrapper"]["terms"][$key] = array(
        '#type' => 'textfield',
        '#size' => 20,
        '#attributes' => array(
            'class' => array('left'),
        ),
    '#value' => $values,
    );  
}

$form['section']['addFive_button'] = array(
    '#type' => 'submit',
    '#value' => t('+5'),
    '#submit' => array('entries_form_add_five_submit'),
    '#ajax' => array(
      'callback' => 'entries_form_commands_add_callback',
      'wrapper' => 'groupWrapper',
      ),
    '#prefix' => "<div class='clear'></div>",
);
dpm($form_state);
}

function entries_form_commands_add_callback($form, $form_state) {
    return $form["section"]["termwrapper"]; 
}

function entries_form_add_five_submit($form, &$form_state){
    $form_state['rebuild'] = TRUE;
    $form_state['fired'] = 1;
    $values = $form_state['values'];
    $form_state['terms'] =  $values['terms'];
    $numterms = count($values['terms']);
    $addfivearray = array_fill($numterms,5,'');
    $form_state['terms'] = array_merge($values['terms'],$addfivearray);

}


/**
 * Implements hook_node_submit().
 */

function entries_form_node_submit($node, $form, &$form_state) {
    $values = $form_state['values'];
    $node->entries_form['term'] = $values['term'];
}

/**
 * Implements hook_node_prepare().
 */
function entries_form_node_prepare($node) {
    if (empty($node->entries_form)){
        $node->entries_form['term'] = array_fill(0, 10, '');
    }
}

/**
 * Implements hook_node_load().
 */
function entries_form_node_load($nodes, $types) {
    if($types[0] == 'entries'){
        $result = db_query('SELECT * FROM {mytable} WHERE nid IN(:nids)', array(':nids' => array_keys($nodes)))->fetchAllAssoc('nid');
        foreach ($nodes as &$node) {
            $node->entries_form['term'] = json_decode($result[$node->nid]->term);
        }
    }   
}

/**
 * Implements hook_node_insert().
 */
function entries_form_node_insert($node) {
  if (isset($node->entries_form)) {
    db_insert('mytable')
      ->fields(array(
        'nid' => $node->nid,
        'term' => json_encode($node->entries_form['term']),
      ))
      ->execute();
  }
}

如何保留已输入的值并保留ajax功能？

任何帮助或指示非常感谢。这是我第一次进入Drupal，所以我确信有一些东西很明显，我很想知道。

Answer 1

好的，我想我终于得到了答案。

在构建表单输入框的foreach中，我设置了'#value'=＆gt; $值，当看起来'#default_value'=＆gt;应该设置$ values。

现在为我工作的代码的更新部分如下

foreach ($form_state['terms'] as $key => $values) {
        $form["section"]["termwrapper"]["terms"][$key] = array(
            '#type' => 'textfield',
            '#size' => 20,
            '#attributes' => array(
                'class' => array('left'),
            ),
        '#default_value' => $values,
        );  
    }

似乎就这么简单。希望这有助于其他人。
