本文实例讲述了drupal中创建hook_user并调用drupal的mail函数发送email的方法。分享给大家供大家参考。具体实现方法如下：

如果想在drupal的用户账号里添加一些自己的内容，就要用到hook_user钩子函数。

例如在wedpage.module中添加一个“创建页面的链接”和一个“发送邮件的form”

复制代码代码如下:function wedpage_user($type, &$edit, &$user, $category = NULL){

if ($type == 'view') {

$items['wedpage'] = array(

'value' => l(t('Create your wedding homepage.'), 'wedpage/add'),

);

$items_mail['send_mail'] = array(

'value' => drupal_get_form('wedpage_mail_form'),

);

$wedpage = array(

t('Wedding homepage') => $items,

t('Send email to your friends') => $items_mail,

);

return $wedpage;

}

}

user的钩子函数就设置成功了！

下面创建mail的发送函数

复制代码代码如下:function wedpage_mail_form(){

$form['wedpage_mail'] = array(

'#type' => 'textfield',

'#size' => 60,

'#prefix' => '<table><tr><td>',

'#suffix' => '</td>',

);

$form['submit'] = array(

'#type' => 'submit',

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

'#prefix' => '<td>',

'#suffix' => '</td></tr></table>',

);

return $form;

}

function wedpage_mail_form_submit($form_id, $form_values){

global $user, $base_url;

if (valid_email_address($form_values['wedpage_mail'])) {

$mailkey = 'wedpage';

$to = $form_values['wedpage_mail'];

$subject = 'wedding web page address';

$url = $base_url.'/ourwedding/'.$user->uid;

$body = $url;

if (drupal_mail($mailkey, $to, $subject, $body)) {

drupal_set_message(t('The mail send successful!'));

}else {

drupal_set_message(t('The mail send failed.'), 'error');

}

}else {

drupal_set_message(t('The e-mail address %mail is not valid.', array('%mail' => $form_values['wpage_mail'])), 'error');

}

}

上面的函数中valid_email_address是一个系统的验证email的函数，drupal_mail函数用于测试邮件是否发送成功！

希望本文所述对大家的drupal二次开发有所帮助。
