Question

thinkphp 搜索查询

$m=M('content');
$where['content'] = array('like','%$_POST['content']%');
$where['title'] = array('like','%$_POST['title']%');
$res=$m->where($where)->select();
哪里有错误？

Answer 1

字符串中写变量用双引号才可以.
$m=M('content');
$where['content'] = array('like',"%{$_POST['content']}%");
$where['title'] = array('like',"%{$_POST['title']}%");
$res=$m->where($where)->select();
