if i render the view with template parser class :

$this->parser->parse('blog_template', $data);

can i add number looping in every row in view, for example :

<?php $i = 0; ?>
  {blog_entries} <? $i++; ?>
     Number : <?=$i?>
     {title}  
     {body}    
     

  {/blog_entries}

I can’t get next loop number with $i++ in template parser method, any idea ?
how must i do ? I want “no PHP code” in my view…

thanks.

Just pass the {i} in with the $data array, as you are with {title} and {body}

can you give me an example?

$entries = array(
   array('title' => 'Hello', 'body' => 'My name is Carl'),
   array('title' => 'Hi There!', 'body' => 'My name is Anita'),
);

$i = 0;
foreach ($entries as $entry)
{
   $i++;
   $entry['i'] = $i;
}

$this->parser->parse('template', array('blog_entries' => $entries));

And then the template:

{blog_entries}
     Number : {i}
     {title}  
     {body}   
     

{/blog_entries}

with your example code, the result is like this :
Number : {i} Hello   My name is Carl
Number : {i} Hi There!  My name is Anita

I wish i can show this :
Number : 1. Hello   My name is Carl
Number : 2. Hi There!  My name is Anita

How must I do??

Colin forgot to add the changed subarray to the parent array

foreach ($entries as $tel=>$entry)
{
   $i = $tel+1;
   $entries[$tel]['i'] = $i;
}

thanks, it’s fixed 😊

Ah.. thanks, xwero. Typed that up really fast.

But hopefully Abdul isn’t always going to rely on a forum to fix simple matters of array manipulation. Hopefully you’ve grasped the concept, Abdul, and don’t just take the code we give you, paste it in, and hope it works.

Thank’s, but i have the problem again :
I was used the array manipulation in my application, like this :

$entries = array(  
                         array('title' => 'Hey', 'body' => 'My Name is Ikhsan'),  
                         array('title' => 'Hi!', 'body' => 'How are you today ?'),  
                         array('title' => 'Hello!', 'body' => 'I'm very Handsome :d ?'),  
                         );            
                
             // i have a simple comment(detail for every posted posting)  
             foreach ($entries as $key => $entry)  
             {  
                 $no = $key+1;  
                 $entries[$key]['no'] = $no;  
                 $entries[$key]['comment'] = array(  
                                 array('name'=>'samson'.$no,'comment'=>'comment'.$no),  
                                 array('name'=>'ryan'.$no,'comment'=>'komentar'.$no)  
                                 );  
                  //detail comment
                 foreach($entries[$key]['comment'] as $keys => $val){  
                             $entries[$key]['comment'][$keys]['numcomment'] = $keys + 1;  
                 }  
             }

And the View, like this :

{blog_entries}  
      Number post : {no}  
      {title}    
      {body}     
      <b>The Comments : </b>  
              {comment}  
                     {numcomment}. {name}   {comment}  
              {/comment}  
 {/blog_entries}

And my question is, with no PHP code in view :
Can i create if statement in template(or if is only in controller? => ) ? (with template parser method)
for example : if {numcomment%2!=0 then <font color=red>{comment}</font>}

Also Note: The Template Parser Class is not a full-blown template parsing solution. We’ve kept it very lean on purpose in order to maintain maximum performance.

The answer is, if you want no code (I think you mean logic) in your view, it HAS to be in the controller.

for example : if {numcomment%2!=0 then <font color=red>{comment}</font>}

So, yeah, that wouldn’t be PHP code, but it’s still some sort of programming language. You’re either going to allow logic in your views or not (logic being conditional statements and loops, etc.)

You might want to instead use something like Smarty, which is a more robust template parser engine.
