PHP 向右侧拉菜单实现代码，测试使用中_php技巧

这个是由asp二级侧拉菜单改的

复制代码 代码如下:

require('../Connections/lr.php');
mysql_select_db($database_lr, $lr);

$query = mysql_query("SELECT * FROM bigclass order by sort");
$j=0;
while($row=mysql_fetch_array($query))
{$j=$j+1;
$bigclassid=$row['bigclassid'];
$bigclassname_leftmenu=$row['bigclassname'];
if ($htmlname==1){
$bigclass_htmlname_leftmenu=$bigclassname_leftmenu;//大类名称
if (substr_count($bigclass_htmlname_leftmenu," ")>0){
$bigclass_htmlname_leftmenu= str_replace(" ","-",$bigclass_htmlname_leftmenu);
}
}
if ($htmlname==0){
$bigclass_htmlname_leftmenu=$bigclassid;
}
?>

• 
  
  
  mysql_select_db($database_lr, $lr);
  $query_small = mysql_query("SELECT * FROM smallclass where bigclassid='$bigclassid' order by sort");
  while($rs=mysql_fetch_array($query_small))
  
  
  {
  $smallclassid_small_leftmenu=$rs['smallclassid'];
  $smallclassname_small=$rs['smallclassname'];//小类名称
  
  if ($htmlname==1){
  $smallclass_htmlname=$smallclassname_small;
  if (substr_count($smallclass_htmlname," ")>0){
  $smallclass_htmlname= str_replace(" ","-",$smallclass_htmlname);
  }
  }
  if ($htmlname==0){
  $smallclass_htmlname=$smallclassid_small_leftmenu;
  }
  
  ?>
  
  
  
  } ?>
  
  
  
  

} ?>
