Thinkphp Learning (iv) volist tag advanced application multiple nested loops _php Tutorial

Action Code:

    Public Function Index () {$prod = I ("Get.prod_en"), $id = i ("Get.id", 0, "int"), if ($prod = = "") {$serviceProduct = array ();// Array of multi-loop traversal

The data is saved in two tables, where the $serviceproduct array is initialized by looping $service = M ("Product_class")->order ("oid ASC")->select (); for ($i = 0; $i < count ($service); $i + +) {Array_push ($serviceProduct, Array ("srvname" = $service [$i] ["PC_CN"], "Product" =>m ("Product") Where ("prod_class_id=". $service [$i] ["Pcid"])->order ("oid ASC")->select ());}

If you want to output a variable in a template, you must pass the variable to the template in the controller, and the system provides the Assign method to assign a value to the template variable, regardless of which type of variable is uniformly used assign assignment. $this->assign ("Serviceproduct", $serviceProduct); $this->display ();} Else{if ($id > 0) {$this->display ("detail");} else{$this->assign (' prod_en ', $prod); $clsList = M ("Question_class")->order ("oid ASC")->select (); $this- >assign (' clslist ', $clsList); $qusList = M ("question")->order ("oid ASC")->select (); $this->assign (' Quslist ', $qusList); $this->display ("list");}}

Template code:

 
  
  
   
  

   
    
   

     {$sp. Srvname} 
   
   
    
    
     
   

     {$pd. prod_cn} 
   
    
     
     
      
   

     | 
   
    
     
   
    
   
    
    
     
   
 
   
   
    
  
   
  
 
  

When using multiple nested loops, you need to specify a key value for each volist by

Determines whether the last element in the array.
