Strange Snippet Results .. Don't know what else to call it?

I have just had the strangest snippet experience and even after a night of sleeping on it thinking it was all me (maybe still is) , I have come back to the same results.

I do not see how the code in the snippet would play any part in this so I will summarize. The overall end result (failure) is the nothing is ever returned by the snippet and/or blank is always returned.. not sure.

Snippet


$output = '';

........... code hear ............
$output = 'Adam';

return $output;

The result is nothing returned. The page itself is resolving and all the page content above and below returns but the area where the snippet is does not get placed.

Now my first thought is of course snippet is not running, tag is bad, cache is stuck. Tried all those. Cleared Cache. Open FS and even emptied all files/folders in ./core/cache.

And if I do this


$output = '';

........... code hear ............
$output = 'Adam';

echo $output;die;

return $output;

I get the echo of $output just one line before it is suppose to be returned.

Also this has no positive effect


$output = '';

........... code hear ............
$output = 'Adam';

return 'ADAM';

So this was my solution and it works... but what is going on


$output = '';

........... code hear ............
$output = 'Adam';

$modx->setPlaceholder('mySnippet',$output);

return '';

Resource


[[!mySnippetTag]]
[[+mySnippet]]

Call me crazy or overworked. Both probably fit.

Update: All tag names are for demo only they are not my actual tag names...

Is your snippet actually called runSnippet? That’s the name of a MODX method, so not a good name for a snippet.

No it was just for explanation but I see how that was not very clear. I will change

This is the actual call

[[!ras.getPickPlays? &relType=`Totals`]]

[[+ras.gamePlayResults]]

Ok I know have a second snippet doing the same thing as the first. This is only 2 out of 14 snippets doing this as well as in formIt I have custom prehooks returning true with no problem but all my custom hooks will not return true.

Now I am running the snippets and hooks through includes to external sources. However as I show above that setup works fine for most.

On a side note I did copy all code into modx manager and removing the included external snippet file and it still did not return anything

Setup is

require_once($modx->getOption('modx.ras').'/snippets/ras.releaseQueue.php');

This is the snippet code

<?php

    $output = '';
    
    $ras =& $modx->raspicks;
    
    $gameInfo = array();
    
    if(!empty($_REQUEST['handicapper']) && !empty($_REQUEST['handicapper'])){
        $picks = $ras->getReleasedPicks($_REQUEST['handicapper'],$_REQUEST['sport']);

        if(!empty($picks)){
            foreach($picks as $pick){
                
                $games = $ras->getGamesFromReleaseId($pick);
                
                if(!empty($games)){
 
                    foreach($games as $game){

                        if($game['pick_r2g_type'] != 'Quick Message'){
                            $gameInfo[] = $ras->setGamePick($game,$pick['pick_rel_datetime']);
                        }
                    }
                }
                
            }
        }
    }

    $picks = '';
    if(!empty($gameInfo)){
        
        foreach($gameInfo as $info){
            
            $params = array(
            'relTime'    => date('Y-m-d H:i:sa',$info["releaseTime"]),
            'date'       => date('Y-m-d',$info["datetime"]),
            'time'       => date('H:i:sa',$info["datetime"]),
            'relType'    => $info["relType"],
            'gamenumber' => $info["game"],
            'matchup'    => $info["gameName"],
            'rating'     => $info["rating"]
            );
            
            $picks .= $modx->getChunk('ras.pickReleaseQueue_Row',$params);
        }
    }

    if($picks != ''){
        $output = $modx->getChunk('ras.pickReleaseQueue_Table',array('picks'=>$picks));
    }

    return $output;

Again if I echo the $output 1 line above the return it has data. My only solution has been to put it all in a placeholder and then add the placeholder tag below the snippet tag

I don’t see anything wrong with the code, although I’ve never seen a snippet with a dot in the name before. That could be confusing the parser when it tries to replace the snippet tag with the return value.

I will change the name just for giggles and see what happens. There are plenty of others with dots and no issue but anything is worth a try.

Also looks like I am not alone (possibly)

here is someone with a similar issue though of course it could be totally unrelated.

The first thing I’d do is add an else for every if:

else {

   return 'Picks is empty';

}

Understood, however I am 100% positive that the issue is not the out being empty.

This will show that there is data in $output;

echo $output;die;
return $output;

This is my work around

$modx->sePlaceholder('myPlaceholder',$output);
return '';

But this returns nothing every time.

return $output;

And this as well

return 'adam';

There is something going on with the way things are sometimes being parsed. Its like the return does not exist and the function result is void.
