HOW TO: Include symbols in rich text editor in MOSS 2007

This post is a contribution from Jaishree Thiyagarajan, an engineer with the SharePoint Developer Support team.

Note: The below walk-through is based off of a publishing site.

We can include symbols in rich text editor in MOSS 2007 in just 3 easy steps.


Copy the image (symbol.jpg) to C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\LAYOUTS\Symbol (where *Symbol* is a new folder). [You can use any name for the image and the folder, but make sure to provide the correct path in Step3 below (line number 2 in the second code snippet below)].


Navigate to master page gallery.  Within editing menu folder, you can find RTE2ToolbarExtension.xml, update the file as shown below [ensure that you checkin and approve this file after the modification is done].

<?xml version="1.0" encoding="utf-8" ?>
    <RTE2ToolbarExtraButton id="symbolInsertion" src="RTESymbolInsertion.js"/>


Create a javascript file named “RTESymbolInsertion.js” to C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\LAYOUTS\1033 and add the below script.


a. I have added 3 symbols to the array (line number 17 in the below code snippet).  You can add many more symbols to the array.  The first parameter is the “symbol” & the second is the “tooltip”.

b. You can arrange the menu items in columns.  I have added the symbols in the first column (line number 23 in the below code snippet).  The first parameter for the function RTE_DD_GenerateMenuItemScriptHtml is the column number.

   1: RTE2_RegisterToolbarButton("symbolInsertion",
   2:                             "_layouts/symbol/symbol.jpg",
   3:                             "Symbols",
   4:                             "Insert symbols",
   5:                             SymButtonOnClick,
   6:                             SymButtonOnResetState,
   7:                             new Array());
   9: function SymButtonOnClick(strBaseElementID, arguments) {
  11:     var docEditor = RTE_GetEditorDocument(strBaseElementID);
  12:     if (docEditor == null) { return; }
  14:     var selectedRange = docEditor.selection.createRange();
  16:     //Array of symbols
  17:     var symbols = [['\u00A9', 'Copyright'], ['\&#151;', 'Emdash'], ['\&#174;', 'Rights']];
  18:     p = symbols.length;
  20:     var sHTML = RTE_DD_GenerateMenuOpenHtml();
  22:     for (i = 0; i < p; i++) {
  23:         sHTML = sHTML + RTE_DD_GenerateMenuItemScriptHtml("1", i, "var docEditor = RTE_GetEditorDocument('" + strBaseElementID + "'); var s=docEditor.selection.createRange();s.text='" + symbols[i][0] + "';RTE_DD_CloseMenu();", symbols[i][0], symbols[i][1], "", "", "");
  24:     }
  26:     sHTML = sHTML + RTE_DD_GenerateMenuCloseHtml();
  27:     RTE_DD_OpenMenu(strBaseElementID, "symbolInsertion", sHTML, "1");
  28:     return true;
  29: }
  31: // The method that is called when the button's state is reset.
  32: function SymButtonOnResetState(strBaseElementID, arguments) {
  34:     var docEditor = RTE_GetEditorDocument(strBaseElementID);
  35:     if (docEditor == null) { return; }
  37:     if (!RTE2_PopupMode(strBaseElementID)) {
  38:         RTE_RestoreSelection(strBaseElementID);
  40:     }
  41:     if (!RTE2_IsSourceView(strBaseElementID)) {
  42:         RTE_TB_SetEnabledFromCondition(strBaseElementID, true, "symbolInsertion");
  43:         return true;
  44:     }
  45:     else {
  46:         RTE_TB_SetEnabledFromCondition(strBaseElementID, false, "symbolInsertion");
  47:     }
  48: }

Once this is done, I can edit my publishing page (screen shots are from a collaboration site where publishing feature is enabled) and point to a content section I want to edit.  This will bring up the rich text editor.  I’ll be able to see the new menu strip and the symbols I added will be usable.
