CI 多表单提交通不过

Jun 23, 2016 pm 01:57 PM
ci submit form

大师们帮看看这段哪错了
if (!empty($_POST['num']) ||
!empty($_POST['title']) ||
!empty($_POST['price']) ||
!empty($_POST['years']) ||
!empty($_POST['season']) ||
!empty($_POST['groups'])
{

$w = array(
foreach($_POST as $k=>$v):
  if(!empty($v)){ 
$k => $v;
}
endforeach;
)
}
就是通不过

这是什么写法,数组里面foreach ? 能行吗? 

这写法闻所未闻啊

我就是想做一个多表单搜索,
就是给搜索同时限制多个条件,每个条件各用一个表单的形式,
有单行文本框,也有下拉菜单,可以不同时限制全部条件,
这个不知道怎么做

为什么要多表单,一个表单里,多个搜索条件不行吗???

不就是过滤掉无效(空值)的传入项吗?

$w = array_diff($_POST, array('', 0));
Copy after login

就可以了

你就是我的大神,崇拜你崇拜的五体投地

if (!empty($_POST['num']) ||
!empty($_POST['names']) ||
!empty($_POST['price']) ||
!empty($_POST['years']) ||
!empty($_POST['season']) ||
!empty($_POST['groups']) ||
!empty($_POST['note']) )
{



$w = array_diff($_POST, array('', 0));}

//分页参数,路由配合
$config['base_url'] = 'http://localhost/ci/index.php/product/search';
$num = $this->product_model->search_page( $w);//这里调用时说$w没定义
$config['total_rows'] = $num;
$config['per_page'] = 80;
$config['uri_segment'] = '3';
$this->pagination->initialize($config);

$pageNum=$this->uri->segment(3,1);
if($pageNum==1){
$offset=0;
}else{
$offset=$config['per_page']*($pageNum-1);
}//分页参数结束

$data['title'] = '商品中心';
// $_where = array('type' => 'newstore');
$data['data'] = $this->product_model->search_paging($w,$config['per_page'],$offset);//这里也说$w没定义

$w = array();if($_POST) {  $w = array_diff($_POST, array('', 0));}//分页参数,路由配合.....
Copy after login
