thinkphp中分页保持查询条件不变的问题

本帖最后由 cffall 于 2013-04-07 12:40:30 编辑 手册中:
import('ORG.Util.Page');// 导入分页类<br />$mapcount      = $User->where($map)->count();// 查询满足要求的总记录数<br />$Page       = new Page($count,25);// 实例化分页类 传入总记录数和每页显示的记录数<br />//分页跳转的时候保证查询条件<br />foreach($map as $key=>$val) {<br />    $Page->parameter   .=   "$key=".urlencode($val).'&';<br />}<br />$show       = $Page->show();// 分页显示输出


这里我的查询条件使用了in
$map['code'] = array('in',$array);
当点第二页时查询条件就不成功。是不是这里不能用in?
php 分页
------解决方案--------------------
这个问题我也遇到了,并且找到了解决的方法了
import('ORG.Util.Page');// 导入分页类
$count=$res->where($sear)->count();//查询数据条数
$Page=new Page($count,2);//实例化分页函数
//分页跳转的时候保证查询条件
foreach($sear as $key=>$val) {
if(!is_array($val)) {
$Page->parameter   .=   "$key=".urlencode($val)."&";//赋值给Page
   }
}
$show=$Page->show();//分页显示输出

这里添加了一个判断就实现了

------解决方案--------------------
//查询
  public function search() {
   $res=D('Info');
   $name=$_REQUEST['name'];
   $sear['name'] = array('like','%'.$name.'%');
   import('ORG.Util.Page');// 导入分页类
   $count=$res->where($sear)->count();//查询数据条数
   $Page=new Page($count,2);//实例化分页函数
   //分页跳转的时候保证查询条件
   foreach($name as $key=>$val) {
    $Page->parameter   .=   "$key=".urlencode($val)."&";//赋值给Page
   }
   $show=$Page->show();//分页显示输出
这是我用的查询分页的代码你看下吧,刚才发的那条虽然能查出来但是不符合规则

这是我总结的文档http://blog.sina.com.cn/s/blog_80742e010101acfq.html,你看下吧

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.
