Okay, I’m running into a very fringe issue and hoping that someone has solved this before.

It has to do with single vs double quoted strings and the way php “expands” variables in strings.

Here’s the basics…

I’m calling magpie in a template that parses php on output.

Everything is working great… UNLESS… an item in the feed has a dollar sign in it.

Then it breaks.

Here’s the relevant part of the code…

{exp:magpie url="{embed:tweet_feed_url}" limit="100" refresh="2" convert_entities="y"}
  <ul id="tweet-feed" class="results-list nobullets">
  {magpie:items}
    <?php $tweet_title = "{magpie:title}"; ?>                  
    <li><?php echo $tweet_title; ?></li>
  {/magpie:items}
  </ul> 
{/exp:magpie}

Here’s something I’ve tried with no success…

$tweet_title = str_replace('$', '$', "{magpie:title}");

And this I know works…

$tweet_title = str_replace('$', '$', 'this is $test feed');

But it won’t let me do this…

$tweet_title = str_replace('$', '$', '{magpie:title}');

... and gives me a “Parse error: syntax error, unexpected T_STRING”

Any help greatly appreciated!

P.S. You can see it break here… http://phishtwit.com ...but you’ll have to page forward until you get to updates from around 3pm Central to see the one with the dollar sign ($) in it (though you won’t be able to see it b/c it breaks!).

TL,

I cannot see it breaking in the link you have provided. Did you mange to sort this one out?

Is there a reason why you cant do the following?

{exp:magpie url="{embed:tweet_feed_url}" limit="100" refresh="2" convert_entities="y"}
  <ul id="tweet-feed" class="results-list nobullets">
  {magpie:items}               
    <li>{magpie:title}</li>
  {/magpie:items}
  </ul>
{/exp:magpie}

John, thanks for the reply.

To see the broken one you’ll need to advance a few pages to 3:07 pm CT.

It immediately follows a Tweet @trent_reznor where you’ll see…

Notice: Undefined variable: htie in /nfs/c01/h07/mnt/3113/domains/jamtopia.com/html/jamadmin/core/core.functions.php(637) : eval()‘d code on line 3027

  </ul>
{/exp:magpie}

 

Yes, because I need to parse the content before I present it.

TL,

You could try the XML encode plugin

{exp:magpie url="{embed:tweet_feed_url}" limit="100" refresh="2" convert_entities="y" parse="inward"}
  <ul id="tweet-feed" class="results-list nobullets">
  {magpie:items}               
    <li> {exp:xml_encode}{magpie:title} {/ exp:xml_encode}</li>
  {/magpie:items}
  </ul>
{/exp:magpie}

    <li> {exp:xml_encode}{magpie:title} {/ exp:xml_encode}</li>
  {/magpie:items}
  </ul>
{/exp:magpie}

John -

I need to do some sophisticated parsing on the value involving complex regular expressions to add links and remove certain words and so on. Will the XML encode plugin will help with that?

TL

Just give it a try. If it doesn’t fit your bill you’ll probably need to write some custom code, but it still should give you a head start.

Well I guess this is just another one of those times where I kept banging away at it until it worked, though I not exactly sure how or why (but don’t really care).

Here’s the relevant code snippet that I changed…

class tl_safedollar {
  var $return_data;    
  /** ----------------------------------------
  /**  Safe XML Dollar Sign ($) Encoding function
  /** ----------------------------------------*/
  function Tl_safedollar($str = '')
  {
  global $TMPL;
  $this->return_data = '';
  if ($str == '')
  {
    $str = $TMPL->tagdata;
    $this->return_data = trim(str_replace('$', '$', $str));
  }
}

Also had to add parse=“inward” to the magpie tag so it’d resolve before trying to call the encoding function.

{exp:magpie url="{embed:feed_url}" limit="100" refresh="2" parse="inward"}

Hope this is helpful to the next person who comes along.

Thanks to the posters above for their guidance.
