Weird revo API problem ... cannot figure it out!!

This is so basic and is just simply not working, and I cannot figure out why.

Snippet MakeUrl:

return $modx->makeUrl($id);

Pretty straightforward ... here is the call:

[[MakeUrl?id=[[+clientlogo_showcase]]]]

[[+clientlogo_showcase]] is an integer. When I make the call, it returns nothing. Now for the weird part ..

If I change snippet MakeUrl to simply "return $id", it returns it with no problem, so it’s certainly passing the number properly.

If I change the call to [[MakeUrl?id=3]], it returns the Url with no problem.

Any idea what could possibly be causing this?

Why dont you just do:



?

Because I have been coding for 10 hours straight and that just makes too much sense

That said - it still doesn’t work, so obviously even though it appears to be a valid int that is being returned from the snippet, it is apparently not.

Here is the snippet:

<?php
$doc = isset($doc) ? $doc : 0;
$depth = isset($depth) ? $depth: 100;
if(!function_exists("getItems"))
{
function getItems($p=0, $d=100, $l=0)
{
global $modx,$modx_charset;
($modx_charset==’UTF-8’) ? $nbsp=chr(0xC2).chr(0xA0) : $nbsp=chr(0xA0);
$c=$modx->getDocumentChildren($p);
foreach($c as $k)
{
$out.=str_repeat($nbsp,$l*5).$k[’pagetitle’]."==".$k[’id’]."||";
if($l<$d) $out.=getItems($k[’id’],$d,$l+1);
}
return $out;
}
}
return getItems($doc,$depth);
?>

This is set to a TV via:

@EVAL return $modx->runSnippet("getChildDocuments",array(’doc’=>17,’depth’=>0));

As a single-select list box. This works like a charm, and outputs the ID of the selected doc, which I am then passing as

[[~[[+clientlogo_showcase]]]]

which is outputting nothing

So clientlogo_showcase is a TV?

If so, shouldn’t it be:

Sorry, I should have stated this is inside a Wayfinder call, so it turns in to a placeholder. When I just put the placeholder call, it does output the proper integer, so that isn’t the issue, so it seems.

I would put an ampersand on the parameter, add some back-ticks, and I wouldn’t used "id" as a parameter name.

Is good advice, however even the call from above doesn’t work:

[[~[[+clientlogo_showcase]]]]

so unfortunately it isn’t in the snippet call

I’m not completely clear on what you’re doing, but it looks like a parsing order problem. Possibly the placeholder tag is in the Wayfinder tag, but when that Wayfinder tag is parsed, Wayfinder hasn’t set the placeholder yet.

Ignoring all of the jumbo about [[MakeUrl]] above ... essentially here is what is happening:

In Wayfinder, TVs "change" to placeholders per the element that it is repeating for the menu.

I have a TV called clientlogo_showcase that is a single select list, pulled via the @EVAL I pasted above, which essentially grabs the children elements under a document by ID. So end of the day, clientlogo_showcase is a single ID.

In the Wayfinder call, when I only put [[+clientlogo_showcase]], it outputs the ID properly. When I change the call to [[~[[+clientlogo_showcase]]]] (as I need it to be the url path), it returns nothing.

Here is how the value looks in the database:



So essentially, the call SHOULD be [[~95]] ...

Can’t figure out why ... but it seems the root of the problem is passing placeholders in Wayfinder.

I can’t for the life of me find the logic in this ... it appears this is what is happening:

- Wayfinder rowTpl passes data contained in a placeholder to a Snippet
- IF the Snippet simply echos the value, it works
- IF the Snippet tries to do any function on the value, it returns null

same with if you pass it to something like [[~xx]]

- If [[+myId]] is 95
- In the Wayfinder rowTpl, [[+myId]] outputs "95"
- In the Wayfinder rowTpl, [[~[[+myId]]]] outputs ""

I am stumped
