Question

您好我制作自定义表单以在自定义模块中添加内容。我创建另一个表单来编辑自定义节点。我想在一个表单中合并两个表单以进行添加和编辑。

function example_add_form($form, &$form_state) {


  $form['name']['title'] = array(
    '#type' => 'textfield',
    '#title' => t('Title'),
    '#required' => TRUE,
  );

  $form['name']['description'] = array(
    '#type' => 'textarea',
    '#title' => t('Description'),
  );


  $form['submit'] = array(
    '#type' => 'submit',
    '#value' => 'Create Order',
  );

  return $form;
}

function example_add_form_submit($form, &$form_state) {


  $node = new stdClass();
  node_object_prepare($node);
  $node->language = LANGUAGE_NONE;
  $node->title = $form_state['values']['title'];
  $node->body[LANGUAGE_NONE][0]['value'] = $form_state['values']['description'];
  node_save($node);

}

这是我的编辑表格，这是我的编辑表格，这是我的编辑表格这是我的编辑表格这是我的编辑表格这是我的编辑表格

function example_edit_form($form, &$form_state, $nid) {

  global $node;
  $node = node_load($nid);

  $form['title'] = array(
    '#title' => 'Title',
    '#type' => 'textfield',
    '#default_value' => $node->title,
  );

  $form['name']['description'] = array(
    '#type' => 'textarea',
    '#title' => t('Description'),
    '#default_value' => $node->body[LANGUAGE_NONE][0]['value'],
  );

  $form['submit'] = array(
    '#type' => 'submit',
    '#value' => 'Update Order',
  );

  return $form;
}

尝试这样，它可能对你有用

在条件

中传递参数nid

// $nid = ''; //by default NULL
// $nid = YOUR_NODE_ID; pass nid when you edit the node

function example_add_form($form, &$form_state, $nid) {

  global $node;
  if(!empty($nid)){
    $node = node_load($nid);
    $body = $node->body[LANGUAGE_NONE][0]['value'];
  }

  // Create Hidden field    
  $form['nid'] = array(
    '#type' => 'hidden',
    '#value' => $nid, // pass node id in form data
  );

  $form['name']['title'] = array(
    '#type' => 'textfield',
    '#title' => t('Title'),
    '#required' => TRUE,
    '#default_value' => isset($node->title) ? $node->title : NULL;
  );


  $form['name']['description'] = array(
    '#type' => 'textarea',
    '#title' => t('Description'),
    '#default_value' => isset($body) ? $body : NULL;
  );


  $form['submit'] = array(
    '#type' => 'submit',
    '#value' => 'Create Order',
  );

  return $form;
}

function example_add_form_submit($form, &$form_state) {

  // check if nid value is empty then create a node otherwise update it
  if(empty($form_state['values']['nid']){
  $node = new stdClass();
  node_object_prepare($node);
  $node->language = LANGUAGE_NONE;
  $node->title = $form_state['values']['title'];
  $node->body[LANGUAGE_NONE][0]['value'] = $form_state['values']['description'];
  node_save($node);
  }else{
    // update node data
  }

}

另外一件事，如果您不想创建nid隐藏字段，那么您可以通过这种方式直接获取表单提交中的nid值

$form_state['build_info']['args']; is an array containing at index 0 the value of argument nid

在自定义模块Drupal 7中添加/编辑表单？
