My QQ: 5642382. My QQ group: 2577162

Function: when posting a post, use the [php] php code [/php] Mark to highlight the php code,
Use the [runcode] Html code [/runcode] Mark to run HTML code (running non-server on the client ).

To add a plug-in, follow these steps:
1. Modify include/common. js
SearchCopy codeThe Code is as follows: function copycode (obj ){
Var rng = document. body. createTextRange ();
Rng. moveToElementText (obj );
Rng. scrollIntoView ();
Rng. select ();
Rng.exe cCommand ("Copy ");
Rng. collapse (false );
}

Add the following at the end of the function:Copy codeThe Code is as follows: function runCode (obj ){
Var winname = window. open (''," _ blank ",'');
Winname.doc ument. open ('text/html ', 'replace ');
Winname.doc ument. writeln (obj. value );
Winname.doc ument. close ();
}

Function saveCode (obj ){
Var winname = window. open ('', '_ blank', 'top = 10000 ');
Winname.doc ument. open ('text/html ', 'replace ');
Winname.doc ument. writeln (obj. value );
Winname.document.execcommand('saveas', '', 'code.htm ');
Winname. close ();
}

2. Modify include/discuzcode. func. php
SearchCopy codeThe Code is as follows: $ discuzcodes ['codecount'] ++;
Return "[\ tDISCUZ_CODE _ $ discuzcodes [pcodecount] \ t]";
}

(Note: You can also use Editplus to directly find the 110th lines of code to add the following code)
Continue to add below:Copy codeThe Code is as follows: // ------- Add the [runcode] Html code [/runcode] to run the Html code
Function runcodedisp ($ code ){
Global $ discuzcodes;
$ Discuzcodes ['pcodecount'] ++;
$ Code = htmlspecialchars (str_replace ('\ "', '"', preg_replace ("/^ [\ n \ r] * (. + ?) [\ N \ r] * $/is "," \ 1 ", $ code )));
$ Discuzcodes ['codehtml'] [$ discuzcodes ['pcodecount'] = "<br> <div class = \" smalltxt \ "style = \" margin-left: 2em; margin-right: 2em \ "> <textarea name = \" runcode $ discuzcodes [codecount] \ "rows = \" 1 \ "cols = \" 95 \ "style = \" height: 200px \ "> $ code </textarea> <br> <input type = \" button \ "value = \" run code \ "onclick = \" runCode (runcode $ discuzcodes [codecount]) \ "> <input type = \" button \ "value = \" Copy Code \ "onclick = \" copycode (runcode $ discuzcodes [codecount]) \ "> <input type = \" button \ "value = \" Save Code \ "onclick = \" saveCode (runcode $ discuzcodes [codecount]) \ "> <script language = \" JavaScript \ "> ffcod = delpost. runcode $ discuzcodes [codecount]. value; ffcod = ffcod. replace (/<br \/>/g, ''); delpost. runcode $ discuzcodes [codecount]. value = ffcod; </script> prompt: you can modify some code before running </div> <br> ";
$ Discuzcodes ['codecs'] ++;
Return "[\ tDISCUZ_CODE _ $ discuzcodes [pcodecount] \ t]";
}

// ------- Add [php] php code [/php] to highlight the php code and perform php syntax coloring.
Function phpcodedisp ($ code ){
Global $ discuzcodes;
$ Discuzcodes ['pcodecount'] ++;
$ Code = phphighlite (str_replace ("\\\" "," \ "", $ code ));
$ Discuzcodes ['codehtml'] [$ discuzcodes ['pcodecount'] = "<br> <div class = \" msgheader \ "> <div class = \" right \"> <a href = \ "###\" class = \ "smalltxt \" onclick = \ "copycode ($ ('phpcode $ discuzcodes [codecount] '); \ "> [Copy PHP code] </a> </div> the PHP code is as follows: </div> <div class = \ "msgborder \" id = \ "phpcode $ discuzcodes [codecount] \"> $ code </div> <br> ";
$ Discuzcodes ['codecs'] ++;
Return "[\ tDISCUZ_CODE _ $ discuzcodes [pcodecount] \ t]";
}

Function phphighlite ($ code ){
If (! Strpos ($ code, "<? \ N ")&&! Strpos ($ code, '<? ') & Substr ($ code, 0, 2 )! = '<? '){
$ Code = '<'.'? '. Trim ($ code ).'? '.'> ';
$ Addedtags = 1;
}
Ob_start ();
$ Oldlevel = error_reporting (0 );
Highlight_string ($ code );
Error_reporting ($ oldlevel );
$ Buffer = ob_get_contents ();
Ob_end_clean ();
If ($ addedtags ){
$ Openingpos = strpos ($ buffer, '<? ');
$ Closingpos = strrpos ($ buffer ,'? ');
$ Buffer = substr ($ buffer, 0, $ openingpos ). substr ($ buffer, $ openingpos + 5, $ closingpos-($ openingpos + 5 )). substr ($ buffer, $ closingpos + 5 );
}
$ Buffer = str_replace ('"'," \ "", $ buffer );
$ Buffer = str_replace ('<br/>', '', $ buffer );
Return $ buffer;
}
// ------- End

3. Continue to modify include/discuzcode. func. php
SearchCopy codeThe code is as follows: $ message = preg_replace ("/\ s * \ [code \] (. + ?) \ [\/Code \] \ s */ies "," codedisp ('\ 1') ", $ message );

Add the following content:Copy codeThe Code is as follows: // ------- runcode
$ Message = preg_replace ("/\ s * \ [runcode \] (. + ?) \ [\/Runcode \] \ s */ies "," runcodedisp ('\ 1') ", $ message );
// ------- Php
$ Message = preg_replace ("/\ s * \ [php \] (. + ?) \ [\/Php \] \ s */ies "," phpcodedisp ('\ 1') ", $ message );
