[Pmwiki-users] Preview function

[Andreas Höcker]

Hi,

 

I have one question.

I use the i18n-de.php and the flexlayout-i18n.php.

I want to ad the preview-function into the flexlayout-i18n.php.

Therefore I pasted this code form the EditPreview-Modul into the
flexlayout-i18n.php:

 

The red marked lines are my changes

 

$PageEditFmt = "

  <form name='wikieditform' action='\$ScriptUrl' method='post'>

  <input type='hidden' name='pagename' value='\$PageName' />

  <input type='hidden' name='action' value='post' />

  <table id='wikiheader' cellpadding='0' cellspacing='0'><tr>

  <td id='wikiheaderlogo' width='4' valign='bottom'>\$WikiImg</td>

  <td valign='bottom'>

    <span id='wikiheadergroup'>\$Group</span> /<br/>

    <span id='wikiheadertitle'>\$Title</span>

  </td>

  <td id='wikiheadercommands' valign='bottom'>

    <input type='submit' value=' $[Save] ' />

    <input type='submit' name='myaction' value='$[Preview]' />

    <input type='reset' value=' $[Reset] ' />

  </td>

  </tr></table>

  <div id='wikitext'>

  <div id='wikieditintro'>

  <a href='\$ScriptUrl/$[PmWiki/TipsForEditing]'>$[TipsForEditing]</a> -

  <a
href='\$ScriptUrl/$[PmWiki/TextFormattingRules]'>$[TextFormattingRules]</a>

  </div>

  <textarea id='wikieditor' name='text' rows='25' cols='80'

  onkeydown='if (event.keyCode == 27) event.returnValue=false;'

  >\$Text</textarea><br /></form>";

 

$myaction = $HTTP_POST_VARS['myaction'];

if ($myaction=="$[Preview]") {  

    $action = "preview";

    $HandleActions = 

        array_merge($HandleActions,array('preview' => 'HandlePreview'));

    $PageHeaderFmt = "<h1>Vorschau \$PageName</h1><h3>Seite ist noch nicht
gespeichert</h3><hr />";

    $PageFooterFmt = "<hr /><table border='0' cellspacing='0'
cellpadding='0' width='100%'>

      <tr><td valign='bottom'><b>Ende der Vorschau: Speichern nicht
vergessen</b></td>

          <td valign='bottom' align='right'>

              <a href='#top'>Anfang der Seite</a></td></tr></table>";

    $HandlePreviewFmtH = array(&$HTMLStartFmt,&$PageEditTitleFmt,

        &$PageEditFmt,&$PageHeaderFmt);

    $HandlePreviewFmtF = array(&$PageFooterFmt,&$HTMLEndFmt);

}

 

function HandlePreview($pagename) {

  global $HTTP_POST_VARS,$HandlePreviewFmtH,$HandlePreviewFmtF;

  global $Text,$HTMLTitle,$GCount;

  $Text = str_replace("\r","",stripslashes($HTTP_POST_VARS['text']));

  $pretext = PrepareText($pagename,$Text);

  $Text = htmlspecialchars($Text,ENT_NOQUOTES);

  $HTMLTitle = "Preview $pagename"; $GCount = 0;

  PrintFmt($pagename,$HandlePreviewFmtH);

  PrintText($pagename,$pretext);

  PrintFmt($pagename,$HandlePreviewFmtF);

}

 

function PrepareText($pagename,$text) {

  global $GroupNamePattern,$PageTitlePattern,$MaxIncludes,$SpaceWikiWords,

    $GroupHeaderFmt,$GroupFooterFmt;

  global $BrowseDirectives,$HandleBrowseFmt;

  $inclcount=0;

  while ($inclcount<$MaxIncludes &&

      preg_match("/\\[\\[include:(.*?)\\]\\]/",$text,$match)) {

    $inclname=$match[1]; $incltext='';

    if (!preg_match("/^$GroupNamePattern([\\/.])$PageTitlePattern\$/",

        $inclname))

      $inclname = FmtPageName('$Group',$pagename).".$inclname";

    $inclpage = RetrieveAuthPage($inclname,"read",false);

    if ($inclpage) $incltext=$inclpage['text'];

    $text = preg_replace("/\\[\\[include:(.*?)\\]\\]/",$incltext,$text,1);

    $inclcount++;

  }

  if (!strstr($text,"[[nogroupheader]]")) {

    $hdname = FmtPageName($GroupHeaderFmt,$pagename);

    if ($hdname != $pagename) 

      { $hdpage=ReadPage($hdname,""); $text = $hdpage['text'].$text; }

  }

  if (!strstr($text,"[[nogroupfooter]]")) {

    $hdname = FmtPageName($GroupFooterFmt,$pagename);

    if ($hdname != $pagename) 

      { $hdpage=ReadPage($hdname,""); $text = $text.$hdpage['text']; }

  }

  Lock(0);

  foreach($BrowseDirectives as $p=>$s) {

    if (strstr($text,$p)) $text = str_replace($p,eval($s),$text);

  }

  return $text;

}

 

Into the i18n-de.php I added the following line:

 

'Preview' => 'Vorschau'

 

And now my question:

 

Why doesn?t this script run?

 

If I change the line

 

if ($myaction=="$[Preview]") {  

 

to

 

if ($myaction=="Vorschau") {  

 

then it works.

 

Can someone help me?
