Stash Parse not parsing EE tags in an addon.

Support Request

Hello.

I’m writing an addon which can take an EE template, replace some variables and then *crucially* parse the EE tags in it and then email it.

I was hoping stash:parse might come to my rescue after a day of poking around various addons code and other options.

So here’s what I want to do:

echo "Template following process 1: $msg_body<br>";
  
  if ( ! class_exists('Stash'))
  {
      include_once PATH_THIRD . 'stash/mod.stash.php';
  }
  
  $stash = new Stash(TRUE); // instantiate with initialising

  $params = array(
   'process' => 'inline',
   'parse_depth' => 5
  );

  $parsed_string = $stash->parse($params, $msg_body);
    
  echo "Template following process 2: $parsed_string<br>";

  return $parsed_string; 

This all seems to work - $msg_body is my template ready to parse. It contains a channel entries tag, which even when I make it as basic as possible, still gives the following error:

Error

The following tag has a syntax error:

{exp:channel:entries}

Please correct the syntax in your template. 

The template code is

{entry_id}
{exp:channel:entries
 channel="clients" 
 entry_id="18813" 
 status="not closed"
}
 {title}
{/exp:channel:entries} 

So unless I’ve missed something obvious, there isn’t a syntax error here.

It seems like this should work, especially as the parse example includes a channel entries tag (https://github.com/croxton/Stash/wiki/{exp:stash:parse})

Unless this only works when using the tag, rather than using Stash in my addon.

Any help/advice appreciated. Thanks.

Update - it works fine if I use that code in my module, just not in my extension. For example, the following module code works fine:

function test_stash(){
  if ( ! class_exists('Stash'))
  {
      include_once PATH_THIRD . 'stash/mod.stash.php';
  }
  
  $msg_body = '
{exp:channel:entries
 channel="clients" 
 entry_id="18813" 
 status="not closed"
}
 {title}
{/exp:channel:entries}';
  
  $stash = new Stash(TRUE); // instantiate with initialising

  $params = array(
   'process' => 'inline',
   'parse_depth' => 5
  );

  $parsed_string = $stash->parse($params, $msg_body);
  
  echo $parsed_string;

 } 

it’s only when I run the same code in an extension that I get an issue. It says there’s a syntax error in the tag, whatever tag I’m using.

Another update - having looked at what causes this error, I found that if I call

ee()->TMPL->fetch_addons(); 

in my extension before I call stash->parse, it works fine without an issue. Hope this helps someone.

Yes that is correct - this is how I do it in Stash’s extension: https://github.com/croxton/Stash/blob/master/system/user/addons/stash/ext.stash.php#L266-L269
