php侧拉菜单漂亮，可以向右或者向左展开，支持FF，IE

IE8必须增加子菜单，隐藏
代码如下:

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

• //
  mysql_select_db($database_lr, $lr);
  $query_num="select count(*) from smallclass where bigclassid='$bigclassid'";
  $rs_num=mysql_query($query_num);
  $myrow_num = @mysql_fetch_array($rs_num);
  $smallclass_num=$myrow_num[0];
  if ($smallclass_num>0){
  echo "id=arrow";
  }
  ?>>
  " class="bigclasslink" >
  mysql_select_db($database_lr, $lr);
  $query_small = mysql_query("SELECT * FROM smallclass where bigclassid='$bigclassid' order by sort");
  if ($smallclass_num==0)
  {
  echo "
  • href=>
  ";
  }
  else
  {
  ?>
  
  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;
  $smallclass_htmlname= tihuan($smallclass_htmlname);
  }
  if ($htmlname==0){
  $smallclass_htmlname=$smallclassid_small_leftmenu;
  }
  ?>
  
  • 
    " class="smallclasslink">
    
    
  
  }
