Hi, my provider changed from PHP5.3 to PHP7.2 - since then my pgn4web BBCodes "pgn" and "pos" didn't work any more. This is my code I originally used:

BBCode "pgn"

<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>
{TEXT}
</textarea>
<script type='text/javascript'>
document.getElementById(pgn4webTextareaId).value = document.getElementById(pgn4webTextareaId).value.replace(/<\s*br\s*\/>/gi, ' ');
height = 268;
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?am=n&d=3000&ss=26&ps=d&pf=d&lcs=TtKN&dcs=LHCg&bbcs=LHCg&hm=b&hcs=mF9_&bd=c&cbcs=RZmI&ctcs=zEtr&hd=j&md=j&tm=13&fhcs=$$$$&fhs=80p&fmcs=$$$$&fccs=v71$&hmcs=M___&fms=80p&fcs=m&cd=i&bcs=TtKN&fp=13&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>

BBCode "pos"

<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>
[FEN "{TEXT}"]
[SetUp "1"]
*
</textarea>
<script type='text/javascript'>
document.getElementById(pgn4webTextareaId).value = document.getElementById(pgn4webTextareaId).value.replace(/<\s*br\s*\/>/gi, ' ');
height = 240;
document.write("<iframe src='" + pgn4webPath + "/board.html?am=n&d=3000&ss=26&ps=d&pf=d&lcs=TtKN&dcs=LHCg&bbcs=LHCg&hm=b&hcs=mF9_&bd=h&cbcs=RZmI&ctcs=zEtr&hd=j&md=j&tm=13&fhcs=$$$$&fhs=80p&fmcs=$$$$&fccs=v71$&hmcs=M___&fms=80p&fcs=m&cd=i&bcs=TtKN&fp=13&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>

Do you have an idea why thecode doesn't work anymore?

Thanks, Michael

extended options for the chessboard display

the suggested [pgn] bbcode only uses a subset of the pgn4web board widget. In order to allow taking advantage of all options of the pgn4web board widget, including setting the board square size, the following bbcode can be used.

bbcode usage:
[pgneo={TEXT1}]{TEXT2}[/pgneo]

html replacement:

<textarea id='pgn4web_' style='display: none;'>
{TEXT2}
</textarea>
<iframe id='pgn4web_board'  frameborder='0' width='100%' height='0' 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 type='text/javascript'>
"use strict";
var eo = "&" + "{TEXT1}";
var pgn4webPath = "";
var pgn4webTextareaIdNum;
if (pgn4webTextareaIdNum === undefined) { pgn4webTextareaIdNum = 1; }
var pgn4webTextareaId = "pgn4web_" + pgn4webTextareaIdNum++;
var pgn4webBoardId = pgn4webTextareaId + "_board";
document.getElementById("pgn4web_").id = pgn4webTextareaId
document.getElementById("pgn4web_board").id = pgn4webBoardId
document.getElementById(pgn4webTextareaId).value = document.getElementById(pgn4webTextareaId).value.replace(/<.*?>/g, ' ');
document.getElementById(pgn4webBoardId).src = pgn4webPath + "/board.html?am=l&d=3000&ss=26&ps=d&pf=d&lcs=TtKN&dcs=LHCg&bbcs=LHCg&hm=b&hcs=mF9_&bd=c&cbcs=RZmI&ctcs=zEtr&hd=j&md=f&tm=13&fhcs=$$$$&fhs=14&fmcs=$$$$&fccs=v71$&hmcs=M___&fms=14&fcs=m&cd=i&bcs=TtKN&fp=13&hl=t&fh=b&fw=p&pi=" + pgn4webTextareaId + eo;
var height = 268;
var multiGamesRegexp = /\s*\[\s*\w+\s*"[^"]*"\s*\]\s*[^\s\[\]]+[\s\S]*\[\s*\w+\s*"[^"]*"\s*\]\s*/m;
var eoMatches = eo.match(/&(h|height)=(\d+)(&|$)/);
if (eoMatches) { height = eoMatches[2]; } 
else { if (multiGamesRegexp.test(document.getElementById(pgn4webTextareaId).value)) { height += 34; } }
document.getElementById(pgn4webBoardId).height = height;
</script>

The {TEXT1} bbocde parameter should be set to a string of URL parameters for the board widgets; the list of available parameters can be displayed browsing to board.html?h=t; in addition the height (shortened as h) parameter can be used to set the chessboard widget height.

This example creates a chessboard with board widget height 400, square size 40 and font moves 20:

[pgneo=h=400&ss=40&fms=20]
[x""]e4 e6 d4 d5
[/pgneo]

the pgn tag defined above only understands PGN inputs; for a FEN string to be understood as PGN input, you have to supply PGN data in this format:

[SetUp "1"]
[FEN "r1bqkb1r/1p3ppp/p1n1pn2/3p4/2P1P3/N1N5/PP3PPP/R1BQKB1R w KQkq - 0 9"]
*

You can easily adapt the pgn above to accept FEN inputs directly, defining as BBcode usage string [pos]{TEXT}[/pos] (note that there seems to be an internal conflict if you try using fen as tag) and as HTML replacement the same code as in the main article, but constructing the PGN data from the FEN string by replacing

{TEXT}

with

[SetUp "1"]
[FEN "{TEXT}"]
*
