我在cronjob中运行PHP脚本,我想每5分钟发送一次电子邮件
我目前的(crontab)cronjob:
10 * * * * /usr/bin/php /mydomain.in/cromail.php > /dev/null 2>&1
cronmail.php如下:
<?php
$from = 'D'; // sender
$subject = 'S';
$message = 'M';
$message = wordwrap($message, 70);
mail("myemail@gmail.com", $subject, $message, "From: $from\n");
?>
但是我在30分钟内没有收到有关此配置的电子邮件.
这个关于wordpress cutom表的问题..
我正在创建一个插件我想检查一个名为wp_school_posttable empty的表是否空.
请参阅下面的代码,它会引发以下错误
Warning: mysql_num_rows() expects parameter 1 to be resource, boolean given in C:\xampp\htdocs\getwp\wp-content\plugins\getwp_P\schools_post_function.php on line 7
**filled**
我的代码:
function schools_post_function()
{
// echo "Sachool POST function";
global $wpdb;
$result = $wpdb->get_results("SELECT postid from wp_school_post WHERE `postid` IS NOT NULL");
if(mysql_num_rows($result=='0'))
{
echo "not filled";
}
else
{
echo "filled";
}
}
我正在尝试启用用户注册并在codeigniter中登录.但是得到错误
致命错误:在第10行的C:\ xampp\htdocs\myfolder\application\views\signup_form.php中调用未定义的函数form_open()
任何建议我的网址看起来像这样
/localhost/myfolder/index.php/signup/
我创建了控制器
<?php
class signup extends CI_Controller {
function Home(){
parent::Controller();
$this->load->library('form_validation');
}
public function index(){
$this->load->view('signup_form');
}
}
?>
