HomeBackend DevelopmentPHP Tutorial缺一个花括号问题

我只知道我的这段代码缺一个花括号 } 但我不知道该填在哪里。我想要的结果是输入学号后可以正常显示,如果有必要的话,我可以把花括号填在任何一个地方后运行的结果截图出来。

<?phpif($search){  if ($xuehao=="")  {	echo"<p align=\"center\"><font color=\"#FF0000\"><b><big>请填写您的学号!</big></b></font></p>";	echo "<meta http-equiv=\"refresh\" content=\"1;url=query.php\">";	exit;	 }     } $query="select * from $student_table where xuehao='$xuehao'"; mysql_query("set names GB2312"); $result=mysql_query($query); $row=mysql_fetch_array($result); if($row==0) {	echo"<p align=\"center\"><font color=\"#FF0000\"><b><big>你还没有注册,或者你的输入有误,请重新输入!</big></b></font></p>";	echo "<meta http-equiv=\"refresh\" content=\"2;url=query.php\">";    exit; }    $query="select id as sm from $student_table where xuehao='$xuehao'"; mysql_query("set names 'GB2312'"); $result=mysql_query($query); $row=mysql_fetch_array($result); if($row[sm]==0) {	echo"<p align=\"center\"><font color=\"#FF0000\"><b><big>你还没有选择课题,请去选题!</big></b></font></p>";	echo "<meta http-equiv=\"refresh\" content=\"2;url=keti_list.php\">";    exit; }   ?><table width="700" border="0" cellspacing="1" cellpadding="0" bgcolor="#333333" align="center">  <tr>   <td width="78" height="30" bgcolor="#FFFFFF">       <div align="center" class="text">         <p class="STYLE1">学生学号</p>      </div>    </td>    <td width=97 height="30" bgcolor="#FFFFFF">       <div align="center" class="STYLE1">学生姓名</div>    </td>    <td width="329" height="30" bgcolor="#FFFFFF">     <div align="center" class="STYLE1"> 课题名称 </div>    </td>    <td width=106 height="30" bgcolor="#FFFFFF">       <div align="center" class="STYLE1">指导教师</div>    </td>    <td width=84 height="30" bgcolor="#FFFFFF">     <div align="center" class="STYLE1">职称</div>    </td>  </tr>   <?php   $n=0;    $query=mysql_query("select * from $jiaoshi_table,$student_table where $jiaoshi_table.id=$student_table.id and $student_table.xuehao='$xuehao'");   mysql_query("set names GB2312");   while($row=mysql_fetch_array($query)){        if(($n%2)!='0'){ 	  echo "<tr bgcolor=#FFFFff>";}	  else{	  echo "<tr bgcolor=#E4E4E4>";	  }     echo"	 <td   height='22' class='STYLE1'> <div align='center'>".$row['xuehao']."</div></td>	 <td   height='22'> 		<div align='center' class='STYLE1'>".$row['name']."</div></td>    <td   height='22' class='STYLE1'> <div align='center'>".$row['subject']."</div></td>    <td   height='22' class='STYLE1'> <div align='center'>".$row['teacher']."</div></td>	<td   height='22' class='STYLE1'> <div align='center'>".$row['zhicheng']."</div></td>  </tr> ";   $n++;   } ?></table> <p> </p><?php  include "foot.php";?>


回复讨论(解决方案)

至少你贴出的代码并没有你说的问题!

至少你贴出的代码并没有你说的问题! 我把花括号加在第10行,它的显示是这样的

至少你贴出的代码并没有你说的问题!

至少你贴出的代码并没有你说的问题! 我把}加在第21行,它的显示是这样的

但是你的代码在我这里并没有报语法错!
当然,我没有你的数据库环境,不可能执行到相关代码
但 “你还没有选择课题,请去选题!”总是可以执行到的

}加在32行 显示是这样 

我把它加在最后一行 

岂能乱加 先读懂程序

岂能乱加 先读懂程序 我是菜鸟,对php处于完全入门阶段……

但是你的代码在我这里并没有报语法错!
当然,我没有你的数据库环境,不可能执行到相关代码
但 “你还没有选择课题,请去选题!”总是可以执行到的 不好意思,我给你看图片的时候其实前面还有16行不太重要的代码,我没有粘。如果把}加在最后一个正确的话,我在哪个地方还应该修改下?

加在最后还有什么问题?

你贴出的代码本身并没有问题!
如果加上那 16行不太重要的代码 就出错的话,那就是那 16行不太重要的代码 的问题了

从你 http://bbs.csdn.net/topics/390451883?page=1#post-394465455 #8的代码上看
   $n++;
   }
} ?>
 


 



的确少了个 }

Notice: Undefined variable: search
提示 $searche 变量为定义

   $n++;
   }
} ?>
 


 



的确少了个 } 是的,然后我就自己试着看在在哪加。是不是我的数据库问题?

Notice: Undefined variable: search
提示 $searche 变量为定义 那我应该怎么办?

$search 是干什么用的,取自上个页面的form表单?详细描述一下你的业务逻辑。
另外,代码要贴全。
