Post "Preview" doesn't work for "pgn4web" chess board used via Custom BBC

[dand]

Hi,
I am using a pgn4web to add a chessboard to forum. I've added a custom BBC code to include this chess board (per this instructions: http://code.google.com/p/pgn4web/wiki/User_Notes_simplemachines). However, the board would not display when Previewed. Works fine when post is submitted, just the Preview doesn't work.

Whose fault is it: chessboard software or Custom BBC mod or SMF?
Does anyone have any idea?


Thanks.

[Kindred]

I expect that it is probably the fault of the custom BBC mod...   it's probably not set to parse the preview page, but does parse on the normal message view.

I would suggest asking on the mod support topic.

I noticed that if I add manualy the code to Sub.php then tag "pgn" works in Preview mode too, here it is:

Code Select Expand


array(
'tag' => 'pgn',
'type' => 'unparsed_content',
'content' => '$1',
  'validate' => create_function('&$tag, &$data, $disabled', 'global $txt; $data = strtr($data, array(\'<br />\' => \'\', \'"\' => \'&quot;\')); $tag[\'content\'] = \'<iframe height="400" width="920" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" src="http://my.ip.address/pgn4web-2.46/board.html?a=f&delay=1000&l=f&pieceFont=alpha&pieceSize=30&squareSize=40&lch=EFF4EC&dch=C6CEC3&bbch=000000&hch=DAF4D7&sb=t&showHeader=t&showMoves=t&textMargin=20&fhch=000000&fontHeaderSize=80pct&fmch=000000&fvch=800000&fcch=396184&hmch=C6CEC3&fontMovesSize=80pct&fontCommentsSize=80pct&sc=t&scosl=f&bch=F0F0F0&highlightMode=border&framePadding=20&horizontalLayout=t&fh=board&fw=page&pt=\' . $data . \'">\' . $txt[\'pgn_no_iframe\'] . \'</iframe>\';'),
),



And here is the mod code that somehow doesn't work in Preview mode:

Code Select Expand


// Add custom BBCode
if (!empty($modSettings['customBBCode_count']))
{
// Find all the tags.
$count = $modSettings['customBBCode_count'];
for ($i = 1; $count; $i++)
{
if (isset($modSettings['customBBCode_tag_' . $i]))
{
$tags[$i] = $modSettings['customBBCode_tag_' . $i];
$count--;
}
}

foreach ($tags as $i => $tag)
{
if (!empty($tag) && !empty($modSettings['customBBCode_enable_' . $i]))
{
// Tag parsing starts here.  Start with the name.
$custom_code = array('tag' => $tag);

// Set block level.
if (!empty($modSettings['customBBCode_block_level_' . $i]))
$custom_code['block_level'] = true;

// Set trim.
if (!empty($modSettings['customBBCode_trim_' . $i]))
{
if ($modSettings['customBBCode_trim_' . $i] == 1)
$custom_code['trim'] = 'inside';
else
$custom_code['trim'] = 'outside';
}

// Check tag type so we don't have to do it again.
if (!empty($modSettings['customBBCode_type_' . $i]))
$tag_type = $modSettings['customBBCode_type_' . $i];
else
$tag_type = 0;

// Find the type and parsing.
if ($tag_type == 2) // At the top because it never uses parsing.
{
$custom_code['type'] = 'closed';

if (!empty($modSettings['customBBCode_text_' . $i]))
$custom_code['content'] = $modSettings['customBBCode_text_' . $i];
}
elseif (empty($modSettings['customBBCode_parse_' . $i])) // No parsing.
{
if ($tag_type == 1)
$custom_code['type'] = 'unparsed_equals_content';
else
$custom_code['type'] = 'unparsed_content';

if (!empty($modSettings['customBBCode_text_' . $i]))
$custom_code['content'] = $modSettings['customBBCode_text_' . $i];
}
else // It parses.
{
if ($tag_type == 1)
if ($modSettings['customBBCode_parse_' . $i] == 1)
$custom_code['type'] = 'unparsed_equals';
else
$custom_code['type'] = 'parsed_equals';

if (!empty($modSettings['customBBCode_before_' . $i]))
$custom_code['before'] = $modSettings['customBBCode_before_' . $i];

if (!empty($modSettings['customBBCode_after_' . $i]))
$custom_code['after'] = $modSettings['customBBCode_after_' . $i];
}

// Add it to the standard tags.
$codes[] = $custom_code;
}
}
}


I have added the following HTML for the tag via mod (and I chose "no parsing", "no trim", "no block level"):

Code Select Expand


<script type='text/javascript'> var pgn4webPath = "/pgn4web"; var pgn4webTextareaIdNum; if (pgn4webTextareaIdNum === undefined) { pgn4webTextareaIdNum = 1; } pgn4webTextareaId = "pgn4web_" + pgn4webTextareaIdNum++; document.write("<textarea id='" + pgn4webTextareaId +"' style='display: none;'>"); </script>{content}</textarea> <script type='text/javascript'> document.getElementById(pgn4webTextareaId).value = document.getElementById(pgn4webTextareaId).value.replace(/<\s*br\s*\/>/gi, ' '); height = 400; multiGamesRegexp = /\s*\[\s*\w+\s*"[^"]*"\s*\]\s*[^\s\[\]]+[\s\S]*\[\s*\w+\s*"[^"]*"\s*\]\s*/m; if (multiGamesRegexp.test(document.getElementById(pgn4webTextareaId).value)) { height += 34; } document.write("<iframe src='" + pgn4webPath + "/board.html?a=f&d=1000&ss=40&ps=30&pf=d&lch=EFF4EC&dch=C6CEC3&bbch=000000&hm=b&hch=DAF4D7&cbcs=UJuI&ctcs=BoVy&hd=j&md=f&tm=13&commentsDisplay=newline&fhch=000000&bd=s&fhs=14&fmch=000000&fcch=396184&hmch=C6CEC3&fvch=800000&bch=F0F0F0&fms=14&fcs=m&cd=i&bcs=WdSO&fp=20&hl=t&fh=b&fw=p&pi=" + pgn4webTextareaId + "' frameborder=0 width=100% height=" + height + " scrolling='no' marginheight='0' marginwidth='0'>your web browser and/or your host do not support iframes as required to display the chessboard</iframe>"); </script>

Does this show why Preview works in the first case, and not with mod?

I think some debugging would be required to figure this out.
The custom BBCode did not work with the BBCode mode?  You had to hard-code it into parse_bbc to make it work?

When you attempt to preview a chessboard, do you see any errors in your SMF error log?

If not, the javascript code is probably a good place to start debugging.  You can work line by line through that code.  This will be a big pain since you have hard-coded the javascript into parse_bbc.  The first thing to check would be whether that javascript works at all, simply by putting in  a line to pop up a message box.  After that -- it is just a slog through the javascript code to find out where you get unexpected values.

Sound like fun?

I just updated forum to 2.0.7 (was usiong 1.1.x).

Preview still doesn't work.

Nothing in the error log.

How do I know does it even get parsed in the Preview mode?

[Kindred]

Is the custom BBC mod even supported on 2.0.x?

(and if you are on 2.0.x, why are youi posting in the 1.1.x support section? )

[dand]

I figured the "Preview" doesn't work in Firefox, but it works in IE 11. So could it be a browser problem after all?

Is there a Firefox setting I could change to make it work?

In case I use firebug to debug, what should I look for?
