如何在Drupal中提交表单

我正在创建一个自定义模块,我想用它来显示模块中的表单。表单查询数据库并显示一些信息。数据库连接正常,数据已成功检索。表单也已成功显示,但我可以弄清楚如何将所有表单链接在一起,以便在提交表单时再次显示页面。我的代码是:

<?php 

function menu($may_cache) {

$items = array();

$items['admin/reporting/report_details'] = array(

  'title' => 'Report: User details by stores',

  'access arguments' => array('access content'),

  'page callback' => 'say_report_details',

  'type' => MENU_CALLBACK,

);  

return $items;
}

// This function should execute the logic if the $_GET variable is set

function say_report_details($values = array()) {

// The $_GET logic will be somtehing like this

//   if (count($_GET) > 0) 

// Get all the form values from the $_GET wit something like:

//   if (count($_GET) > 0) {

  //   $start = mktime(0, 0, 0, $_GET['from_month'], $_GET['from_day'],

 $_GET['from_year']);

  //   $end = mktime(23, 59, 59, $_GET['to_month'], $_GET['to_day'], $_GET['to_year']);

 if ($_GET['store'] > 0) {

  $form = drupal_get_form("report_details_form");

   $output = theme("report_page", $form, $output);

return $output;
 }


function report_details_form() {

 $form["search"] = array(

'#type' => 'fieldset',

'#title' => t('Search params'),

'#collapsible' => FALSE,

'#tree' => TRUE,

 );

   for ($i = 1; $i < 32; $i++) {

   $days_opt[$i] = $i;

                            }
  for ($i = 1; $i < 13; $i++) {

 $month_opt[$i] = $i;

  }

 for ($i = 2008; $i < date("Y") + 3; $i++) {

 $year_opt[$i] = $i;

  }

$form["search"]["from_day"] = array(

'#type' => 'select',

'#title' => 'Date from',

'#options' => $days_opt,

'#default_value' => (($_GET['from_day'] == "") ? date("d") : $_GET['from_day'])

);

$form["search"]["from_month"] = array(

'#type' => 'select',

'#title' => '&nbsp;',

'#options' => $month_opt,

'#default_value' => (($_GET['from_month'] == "") ? date("m") : $_GET['from_month'])

);

$form["search"]["from_year"] = array(

'#type' => 'select',

'#title' => '&nbsp;',

'#options' => $year_opt,

'#default_value' => (($_GET['from_year'] == "") ? date("Y") : $_GET['from_year'])

);

$form["search"]["to_day"] = array(

'#type' => 'select',

'#title' => 'Date to',

'#options' => $days_opt,

'#default_value' => (($_GET['to_day'] == "") ? date("d") : $_GET['to_day'])

);

$form["search"]["to_month"] = array(

'#type' => 'select',

'#title' => '&nbsp;',

'#options' => $month_opt,

'#default_value' => (($_GET['to_month'] == "") ? date("m") : $_GET['to_month'])

 );

$form["search"]["to_year"] = array(

'#type' => 'select',

'#title' => '&nbsp;',

'#options' => $year_opt,

'#default_value' => (($_GET['to_year'] == "") ? date("Y") : $_GET['to_year'])

 );

$result = db_query('SELECT taxonomy_term_data.name, taxonomy_term_data.tid FROM 

    taxonomy_term_data WHERE vid = 10');

  $strs = array("all" => "All");

  foreach ($result as $store) {

  $strs[$store->tid] = $store->name;

}

$form["search"]["store"] = array(

'#type' => 'select',

'#title' => 'Stores',

'#options' => $strs,

'#default_value' => $_GET['store']

);

 $form["submit"] = array("#type" => "submit", "#value" => "Show report");

  return $form;

 }

   function theme_report_page($form, $result = array()) {

  $output = '

<div id="report_form">

 '. $form .'

</div> 

 <div id="report_result">
 '. $result .'
 </div>
 ';

 return $output;

 }

  function theme_report_details_form($form) {

 unset($form['search']['from_day']['#title']);

 unset($form['search']['from_month']['#title']);

 unset($form['search']['from_year']['#title']);

unset($form['search']['to_day']['#title']);

unset($form['search']['to_month']['#title']);

unset($form['search']['to_year']['#title']);

unset($form['search']['store']['#title']);

  $output = "<fieldset>

  <legend>Search params</legend>

<div class='fieldtitles'>". t('Date From') .":</div>

". drupal_render($form['search']['from_day']) ."

". drupal_render($form['search']['from_month']) ."

". drupal_render($form['search']['from_year']) ."

<div class='clearing'>&nbsp;</div>

<div class='fieldtitles'>". t('Date To') .":</div>

". drupal_render($form['search']['to_day']) ."

". drupal_render($form['search']['to_month']) ."

". drupal_render($form['search']['to_year']) ."

<div class='clearing'>&nbsp;</div>

<div class='fieldtitles'>". t('Store') .":</div>

". drupal_render($form['search']['store']) ."

  <div class='clearing'>&nbsp;</div>

 ". drupal_render($form['submit']) ."

 </fieldset>";

 unset($form['search']);

  $output .= drupal_render($form);

 return $output;
 }


 function report_details_form_submit($form_id, $form_values) {

  $query = "";

// This next line is the one we are having an issue right now, as is trowing an 

     error due to $form_values is empty for some UNKNOWN reason...

  foreach ($form_values['search'] as $key => $value) {

 $query .= "&". $key ."=". $value;
 }

 return array('admin/reporting/report_details', $query);
}

我没有查看表单的所有细节,但D7的提交功能应如下所示:

function my_module_example_form_submit($form, &$form_state) {
  // do something
}

我认为应该解决这个问题。如果没有,请查看此链接:http://api.drupal.org/api/drupal/includes%21form.inc/group/form_api/7

答案 1 :(得分:0)

请阅读&amp;按照mikewink提供的答案。

此外,在我创建的三种工作表单中,菜单项数组如下:

$items = array();
$items['admin/config/system/dataforms/SiteAccessform']=array(
    'title'=>'Site Access' //this should be watever the Title of your form is
    ,'description'=>'Configuration for the Data Forms module' //shows up by your menu item as it's description (where applicable)
    ,'page callback'=>'drupal_get_form' //this, as I understand it, is required for forms to work properly (& may be part of the cause of your problems)
    ,'page arguments'=>array('dataforms_main_form') //IMPORTANT this is the actual name of your function that will be executed to produce the form 
    ,'access arguments'=>array('administer settings for dataforms') //??
    ,'type'=>MENU_CALLBACK//these work when the path is accessed though no menu items are created
    ,
);

还有几点,当你在一个特定的'menu'项目上,它的页面参数数组元素设置为你的表单时,它只将它视为一个表单。也就是说,一个函数将是唯一能够创建表单的函数(根据我的经验)。因此,如果适用的话,在该函数中使用逻辑来生成不同的形式......(而不是试图使用一个调用另一个函数的按钮......这对我来说不起作用)。

另外,再次回顾mikewink的回答,$ form_state变量是存储你想要注意的状态的方法,&amp;不是标准的$ _GET或$ _POST变量。

此链接可能会有所帮助:https://api.drupal.org/api/drupal/developer!topics!forms_api_reference.html/7

但是,我从示例模块中收集了最有价值的信息:https://drupal.org/project/examples
