有人可以帮助我保存表格吗？

Question

下面是我的用户表单的 admin.inc 文件。在这个例子中，我有return system_settings_form($pppp_form); 我真正想要的是自己制作一个保存按钮并在用户按下保存时保存所有这些值......这个表单代码在下面做同样的事情并且它可以工作，但我想做我自己的保存表单，因为这个表单不保存我想要从复选框中获得的值有人可以帮助我制作我自己的表单吗？我真的需要帮助！！非常感谢你..！

/**
 * Settings form for the user.
 */
function pppp_admin_settings() {

  $pppp_form['pppp_key'] = array(
      '#type'          => 'textfield',
      '#title'         => t('pppp'),
      '#default_value' => variable_get('pppp_key', ''),
      '#description'   => t('pppp.'),
      '#required'      => TRUE,
      '#size'          => 28,
      '#required'      => TRUE,
    );

    $pppp_options = array(
      '0'       => 'No Values',
      '100'     => '100',
      '500'     => '500',
      '1000'    => '1000',
      '5000'    => '5000',
      '50000'   => '50000',
      '1000000' => '1000000'
    );
    $pppp_form['pppp_number_select'] = array(
      '#type'          => 'select',
      '#options'       => $pppp_options,
      '#description'   => t('Select how many values you want to check.'),
      '#default_value' => variable_get('pppp_number_select', '0'),
    );

    $pppp_severity_levels = variable_get('pppp_severity_levels', array());

    $pppp_severity_options = array();

    foreach (watchdog_severity_levels() as $pppp_severity_number => $pppp_severity) {
      $pppp_options[$pppp_severity_number] = check_plain(drupal_ucfirst(
        $pppp_severity));
    }

    $pppp_form['pppp_severity'] = array(
      '#type'        => 'fieldset',
      '#title'       => t('pppp.'),
      '#collapsible' => TRUE,
      '#collapsed'   => TRUE,
    );

    $pppp_form['pppp_severity']['pppp_severity_levels'] = array(
      '#type'          => 'checkboxes',
      '#title'         => t('Type of log messages'),
      '#options'       => $pppp_severity_options,
      '#default_value' => array_values($pppp_severity_levels),
      '#required'      => TRUE,
    );

    return system_settings_form($pppp_form);

}

Answer 1

system_settings_form($form) 函数是一种快捷方式，可让您构建表单而不必担心保存按钮/提交处理程序（这些是自动添加的）。

如果你想构建一个完整的表单，包括提交处理程序等，你必须定义一个表单函数和一个表单提交处理程序，然后通过 drupal_get_form('MY_FORM_NAME_admin_settings_form'); 调用它。 所以

定义一个表单函数

这可以有任何你想要的名字

MY_FORM_NAME_admin_settings_form($form, &$form_state){
  //Put your form array here- 
  //Add a submit button
  $form['submit'] = array(
    '#type' => 'submit', 
    '#value' => 'Save'
  ); 
  return $form; 
}

定义提交处理程序

提交此表单后，它会自动尝试调用 MY_FORM_NAME_admin_settings_form_submit，因此我们必须定义提交处理程序

  MY_FORM_NAME_admin_settings_form_submit($form, &$form_state){
    //All the input is in the $form_state['input'] so we'll put it in a message to see what's happening. 
    drupal_set_message('<pre>' . print_r($form_state['input'], true) . '</pre>'); 
    //Do your thing with the data 
    //Save it via variable set
  }

打印此表格

在需要的地方通过 drupal_get_form 调用此表单。

drupal_get_form('MY_FORM_NAME_admin_settings_form'); 

Answer 2

您的问题有点含糊，但我认为您正在寻找提交按钮，它允许您定义一个自定义回调函数来处理数据。

$pppp_form['actions']['submit'] = array(

'#type' => 'submit',

'#value' => t('Delete'),

'#weight' => 15,

'#submit' => array('pppp_form_submit_callback'),
);

Answer 3

在您发布的代码中，您有 1 个额外的右大括号 }。 对于表单提交，您可以添加

$pppp_form['submit'] = array(
    '#type' => 'submit',
    '#value' => 'Submit'
  );
