PHP Unlimited class classification PHP infinite pole classification display PHP infinite pole classification drop-down box PHP infinite pole classification letter

If you write a system, you will often use the column management

Column Classification Multi-level more need to achieve unlimited class classification, the code is as follows

One, the use of the drop-down menu

/*  Infinite class * * logical recursive Get type *hid ancestor column ID *step subordinate column prefix *tid seleted option ID */function logicgettypelist ($datatable = ' Lanmu_class ', $hid =0, $step = ", $tid =-1) {static $TypeList ="; $query = "select * from ' $datatable ' WHERE heid= $hid ORDER by px ASC"; $arrs =m Ysql_query ($query), while ($row = @mysql_fetch_assoc ($arrs)) {echo $step; $TypeList. = ("". $step. $row [' class ']." \ r \ n ");  Category name Logicgettypelist ($datatable, $row [' id '], $step. '--', $tid);} return $TypeList;}

Second, column management

The code is probably as follows and needs to be modified according to the situation

 
  
 
  
 
  
 
  "Size=" 3 "  echo $row [' id '];? >,this.value) "/>"    "> Edit" "'}" > Delete "" "> Picture Set" 
 
  
 
  

The above introduces the implementation of PHP Unlimited class classification, including PHP, infinite level of content, I hope that the PHP tutorial interested in a friend helpful.
