这是我使用hook的自定义模块,
假设我想将参数传递给custom1_default_form函数调用,我应该如何传递参数?
<?php
function custom1_block($op,$delta=0){
if($op=='list'){
$block = array();
$block[0]['info']=t('hello world');
return $block;
}else if($op=='view'){
$block_content = '<p>THIS IS MY FIRST BLOCK</p>';
$block['subject'] = 'HELLO WORLD';
$block['content'] =drupal_get_form('custom1_default_form');
return $block;
}
}
function custom1_default_form () {
$form = array();
$form['nusoap_urls']['txt_name'] =
array('#type' => 'textfield',
'#title' => t('Please enter your name'),
'#default_value' => variable_get('webservice_user_url',''),
'#maxlength' => '40',
'#size' => '20',
// '#description' => t('<br />Root directory used to present the filebrowser user interface.')
);
$form['submit'] = array(
'#type' => 'submit',
'#value' => t('Save Details'),
);
return $form;
}
function custom1_default_form_validate (&$form, &$form_state) {
if(($form_state['values']['txt_name']) == '') {
form_set_error('user_webservice', t('Enter a name'));
}
}
function custom1_default_form_submit ($form_id, $form_values) {
// drupal_set_message( print_r($_POST));
// $message = 'You have submitted the ' . $form_id . ' form which contains the following data:<pre>' . print_r($form_state['values'],true) . '</pre>';
//drupal_set_message(t($message));
//drupal_set_message(t($form_values['values']['txt_name']));
// print_r($form_values['values']);
$GET_TXT_FIELD_VALUE = $form_values['values']['txt_name'];
$INSERT_QUERY = "INSERT INTO sample (test_name) VALUES ('$GET_TXT_FIELD_VALUE')";
if (db_result(db_query("SELECT COUNT(*) FROM {sample} WHERE test_name = '%s';", $GET_TXT_FIELD_VALUE))) {
// User doesn't exist
drupal_set_message(t('ALREADY EXIST.....'));
}else{
db_query($INSERT_QUERY)or die('Execution Failed');
if(db_affected_rows()==1){
drupal_set_message(t('VALUE INSERTED SUCCESSFULLY'));
}else{
drupal_set_message(t('VALUE INSERTED FAILED'));
}
}
}

如果您想通过网址传递参数,请使用arg()
:
function custom1_default_form() {
// Assuming the URL is http://example.com/admin/content/types:
$arg1 = arg(1); // $arg1 = 'content'
$arg2 = arg(2); // $arg2 = 'types'
// ...
}
如果您只想通过drupal_get_form()
调用将参数传递给表单,只需将参数作为附加参数添加到drupal_get_form()
:
$block['content'] = drupal_get_form('custom1_default_form', $arg1, $arg2);
// ...
function custom1_default_form($form_state, $arg1, $arg2) {
// ...
}

我发现在Drupal 6.20中你应该为回调函数定义添加一个伪参数:
$ block ['content'] = drupal_get_form('custom1_default_form',$ arg1,$ arg2);
// ...
function custom1_default_form($ dummy,$ arg1,$ arg2){//查看$ dummy中存储的内容 // ... }

尽可能避免使用arg()函数:
尽可能避免使用此功能,因为结果代码很难 阅读。在菜单回调函数中,尝试使用命名参数。 请参阅menu.inc中的说明,了解如何构造回调 接受争论。尝试使用此功能加载时 来自当前路径的元素,例如在节点页面上加载节点, 请改用menu_get_object()。
