当由服务器的cron运行时,Drupal的profile\u save\u profile在hook\u cron中不起作用

我对以下的实现有问题 hook_cron 在Drupal 6.1.3中。

问题在于,当服务器上的“真实”cron调用Drupal cron时,最后一行——更新概要文件——似乎不起作用。

当我手动运行cron时(例如通过 /admin/reports/status/run-cron

有什么建议可以解释是什么原因造成的吗?

(注意,因为有人会建议:成员通过Drupal之外的方式加入,并且每晚都会上传到Drupal,所以Drupal内置的欢迎信不会起作用(我认为)。)

<?php
function foo_cron() {
    // Find users who have not received the new member letter, 
    // and send them a welcome email

    // Get users who have not recd a message, as per the profile value setting
    $pending_count_sql = "SELECT COUNT(*) FROM {profile_values} v 
     WHERE (v.value = 0) AND (v.fid = 7)"; //fid 7 is the profile field for profile_intro_email_sent
    if (db_result(db_query($pending_count_sql))) { 
        // Load the message template, since we 
        // know we have users to feed into it.
        $email_template_file    =   "/home/foo/public_html/drupal/" . 
                                    drupal_get_path('module', 'foo') .

        fclose($email_template_fh);

        $query = "SELECT v.uid FROM {profile_values} v 
        WHERE (v.value = 0) AND (v.fid = 7)";    
        $result = db_query(($query));
        // Loop through the uids, loading profiles so as to access string replacement variables
        while ($item = db_fetch_object($result)) {

            $email_text = t($email_template_data, $translation_key);

            $change = array(
