thinkphp template volist label nested loop output multidimensional Array method _php instance

This article describes the thinkphp template volist label nested loop output multidimensional array method. Share to everyone for your reference, as follows:

The use of nested volist tags in thinkphp enables the output of multidimensional arrays.

Volist nested use

A general two-dimensional array that can be directly looped out with volist tags. For multidimensional arrays, you need to use the volist tag again to nest the loop output for the array members.

To build a multidimensional array:

$food = Array (); $food [0][' Fruits '][0][' fruits1 '] = ' Apple 1 '; $food [0][' Fruits '][0][' fruits2 '] = ' orange 1 '; $food [0][' fruits '] [0] [' fruits3 '] = ' banana 1 '; $food [0][' vegetables '] = ' cabbage 1 '; $food [1][' Fruits '][1][' fruits1 '] = ' Apple 2 '; $food [1][' Fruits '][1][' Fruits2 '] = ' orange 2 '; $food [1][' Fruits '][1][' fruits3 '] = ' banana 2 '; $food [1][' vegetables '] = ' cabbage 2 ';

Use the Print_r () function to print out the array as follows:

Array (  [0] = = Array ([      fruits] = = Array (          [0] = = Array            (              [Fruits1] = Apple 1              [FRUITS2] + orange 1              [fruits3] + Banana 1            )        )      [vegetables] + cabbage 1    )  [1] = = Array    (      [fruits] = = Array        (          [1] = = Array            (              [fruits1] = Apple 2              [fruits2] = orange 2              [FRUITS3] + banana 2            )        )      [vegetables] + cabbage 2    ))

Assign the variable to the template in the corresponding module operation (such as Index/display) and output the template:

$this->assign ("Food", $food); $this->display ();

Template tpl/default/index/display.html:

Food varieties:


 
   
  
    
   
    
Fruit 1:{$f [' Fruits1 ']}
 
   
    
Fruit 2:{$f [' Fruits2 ']}
 
   
    
Fruit 3:{$f [' Fruits3 ']}
 
  
    
  
   
Vegetables: {$vo [' vegetables ']}
  
   

 
  

Inside the template, the $food variable is first looped out. Because the member fruits of the $food array is also an array, the $VO [' fruits '] variable is recycled (note that there is no $ symbol).

The output results are as follows:

Food variety: Fruit 1: Apple 1 fruit 2: Orange 1 Fruit 3: Banana 1 Vegetable: Cabbage 1 fruit 1: Apple 2 fruit 2: Orange 2 Fruit 3: Banana 2 vegetable: Cabbage 2

In this way, the array of more dimensions can be looped out.
