Question

当用户按类别搜索时，如果用户想要通过移动搜索，则显示数据，则显示数据。

用户可以按类别或状态或移动设备搜索任何记录。

这是我试过的代码。

     <?php
     if(isset($_POST['submit']))
 {
   $status = $_POST['status'];
  $priority = $_POST['priority'];
   $ticket = $_POST['ticket'];
    $mobile = $_POST['mobile'];
      echo $mobile;
    $query = "SELECT * FROM ticketreg WHERE 1";
    if(isset($status) && $status != '') {
   $query .= " And status Like'%$status%'";
   }
    if(isset($priority) && $priority != '') {
   $query .= " OR priority Like'%$priority%'";
    }
   if(isset($ticket) && $ticket != '') {
   $query .= " OR ticket Like '%$ticket%'";
  }
   if(isset($mobile) && $mobile != '') {
  $query .= " OR EMAILID Like '%$mobile%'";
 }




$result = mysql_query($query); 


while($row = mysql_fetch_array($query))
 {



 ?>

请给我一些暗示。这里是html代码。

   <form name="frmSearch" method="post" action="searchresult.php">
      <table width="100%" cellspacing="0" cellpadding="0" border="0" >

试试这个

 $query = "SELECT * FROM ticketreg WHERE 1";
    if(isset($status) && $status != '') {
   $query .= " And status Like'%$status%'";
   }
    if(isset($priority) && $priority != '') {
   $query .= " OR priority Like'%$priority%'";
    }
   if(isset($ticket) && $ticket != '') {
   $query .= " OR ticket Like '%$ticket%'";
  }
   if(isset($mobile) && $mobile != '') {
  $query .= " OR EMAILID Like '%$mobile%'";
 }

编辑：

 $query = "SELECT * FROM ticketreg WHERE ";
    if(isset($status) && $status != '') {
   $query .= "status Like'%$status%' OR";
   }
    if(isset($priority) && $priority != '') {
   $query .= " priority Like'%$priority%' OR ";
    }
   if(isset($ticket) && $ticket != '') {
   $query .= " ticket Like '%$ticket%' OR ";
  }
   if(isset($mobile) && $mobile != '') {
  $query .= " EMAILID Like '%$mobile%' OR ";
 }
 $query = substr($query,0,-3);
