Passing a parameter into an Additional Pages page?

Hi All,

I was wondering if it was possible (and if so, how?) to pass a parameter (for example a category id or photo id) into a page added using Additional Pages?

Thanks.

Re: Passing a parameter into an Additional Pages page?

Hi ddtddt

I have a page listing the root categories of my site and showing the last 5 added images.  I'd like a link for each category that would take the user to a new page that shows more of the recent images for the selected category and maybe even page through the rest of the images in the category and it's children.

Re: Passing a parameter into an Additional Pages page?

Thanks for the suggestion.

I've had a look and while it does do some of the things, it's a bit limited.  I can't see any way to put a block on it's own page (for example) and it doesn't allow paging through more images in a category (for example if I'm showing the last twenty of a particular category, there's no way to add a link to see 21 to 40).

Re: Passing a parameter into an Additional Pages page?

I assume it's okay to answer my own question here, and hopefully someone else will find this useful later.

So rather than try and pull apart PWG Stuffs, I took a different approach more akin to my original request.

I added the following to my Personal Plugins:

Code:

add_event_handler('AP_render_content', 'addUrlTokens');
function addUrlTokens($content) {
  global $tokens;
  
  $data = '<script type="text/javascript">var tokens = {}; ';
  if ((isset($tokens)) && (count($tokens) > 0)) {
    for ($i=0; $i < count($tokens); $i+=2) {
      if (isset($tokens[$i+1])) {
         $data .= "tokens['" . $tokens[$i] . "'] = '" . $tokens[$i+1] . "';";
      }
    }
  }
  $data .= '</script>';
  
  return $data . $content;
}

This takes all the tokens from the URL and creates them as a javascript hash at the start of Additional Page's pages called tokens.  So you'll end up with something like this at the top of your content:

Code:

<script type="text/javascript">var tokens = {}; tokens['page'] = 'test2';tokens['wibble'] = 'cli';</script><style type="text/css">

In this example, the URL used was "index.php?/page/test2/wibble/cli"

You can then use it in your javascript, something like:

Code:

<div class="d-flex justify-content-center">
  <div id="data" class="mt-2"></div>
</div>

<script type="text/javascript">
Object.keys(tokens).forEach(function (key) { 
    var value = tokens[key]
    $('#data').append('<div>' + key + ' = ' + value + '</div>');
});
</script>

Obviously you don't need to iterate the array, but do remember to check the key exists before attempting to use it.

Edit: Obviously this won't work with stand-alone pages, but then you probably have access to the URL parameters using more standard methods.
