Passing variables to Plugins as Parameters

Seems like nobody is interested in this topic? If the question is too stupid please let me know.

Hi hereward,

Are you positive that {intro} is being parsed to what you expect?

Try something like:

{exp:weblog:entries weblog="my_weblog"}
   Variable: {intro}
   {exp:my_plugin:my_method my_variable="{intro}"}
{/exp:weblog:entries}

And have the plugin return (or better yet var_dump()) the variable.

What do you see?

You need to put ‘parse=”inward”’ in the entries plugin to get it to process first.

Actually the entries tag is a weblog module tag, and does not need that parameter to be parsed before plugin tags contained within the entries tag, Erin. That parameter is used when you have multiple nested plugin tags that you need to outer to be parsed first. the_butcher’s advice is correct in this case, hereward.

Whoops, I knew that..I just solved a parse problem myself with the ‘inwards’ parameter and forgot that.

Sorry for the wrong information.

Hi thanks for your reply. i have been away for a while. I am not sure what you are driving at there, but I can assure you that the variable has valid data in it.

In fact I was able to get the plugin working using the variable as parsed data rather than as a plugin parameter, so I think I have already addressed this question.

example:

{exp:weblog:entries weblog="my_weblog"}
   {exp:my_plugin:my_method}
      {intro}
   {/exp:my_plugin}
     
{/exp:weblog:entries}

The problem is, when the variable is passed as a parameter to the plugin it becomes null when the PHP executes the code.

As a final test … does anybody have a working example of ANY custom plugin that can receive variables as parameters? If anyone can demonstrate that such a beast exists i would eat my hat.

Thanks (:

Hmm, too many to mention. Including most of the bundled 1st party plugins. You have referenced the global $TMPL object, yes?

<?php
class my_plugin
{
  function my_plugin()
  {
  }
  function my_method()
  {
    global $TMPL;
    var_dump($TMPL->fetch_param('my_variable'));
  }
}
?>

Yes, the plugin itself has no bearing on whether or not another tag’s variable can be used as a parameter. I have a feeling that your parameter is being broken by either a quote in the data or in field formatting for {intro} (auto XHTML, Markdown, etc.).
