Error on line 23...

Hi alfonsoml,

thx for your reply. I think i can't give much more code because this is all what i need for the editor, isn't?
however, i destroy the editor. The same way like the sample.

I will try to explane my problem again:)

I got a page with a table of pages, loaded by AJAX.
When i call add/edit page a thickbox will be loaded.
In AJAX will call AddPage.php, here al the variables will be set and some classes will be initialized:

require_once(ROOTPATH . 'b-layer/functions/pages.functions.php');
require_once(ROOTPATH . 'b-layer/functions/page.functions.php');

$PagesFunction = new Pages_Functions();
$PageSettings = new PageSettings();
    
$PageType = "Add";
$user_id = $_POST['uid_set'];
$titlebar = "";
$title = "";
$description = "";
$keywords = "";
$content = "";
$filename = "";
$templatename = "";
$selected_value = "";
$protectedPass = "";
require(ROOTPATH . 'p-layer/templates/PageForm.tpl');

The PageForm is the form with all boxes:

<tr>
   <td>Keywords</td>
   <td><textarea id="keywords" name="keywords" style="width:300px;" rows="3"><?php echo $keywords; ?></textarea></td>
   <td></td>
</tr>
<tr>
   <td colspan="3">
      <div id="editor1"></div>
            <div id="content_info">Content: <?php echo $content ?></div>
            <script type="text/javascript">
                var editor;
                var html = document.getElementById('content_info').innerHTML;
                editor = CKEDITOR.appendTo('editor1');
                editor.setData(html);
   </script>
   </td>
</tr>
<tr>
   <td>Filename</td>
   <td><input type="text" id="filename" name="filename" style="width:300px;" value="<?php echo $filename; ?>"></td>
   <td></td>
</tr>

if i want to save the filled form a JavaScript function will be called:

<button type="submit" onclick="SaveForm('<?php echo $PageType; ?>'); return false;" ondblclick="SaveForm('<?php echo $PageType; ?>'); return false;" name="Save" style="border:0; background:transparent; cursor:pointer; float:right;"> 
   <img src="<?php echo WEBPATH; ?>/images/accept.png" alt="Save" width="32px" height="32px"/> 
</button>

The function will get al the values of the inputfields en will send them via AJAX to a php file where it will be checked and saved.
If there is a problem, the variables will be set and the PageForm will be called again.
This is the Function SaveFrom:

function SaveForm(ProgressType) {
   var content = CKEDITOR.instances.editor1.getData();
    editor.destroy();
   editor = null;

// get all values of the inputs and will send them to the php file.

For editing a page, will be called the same form and will EditPage.php set before including the form first the variables.

I hope you got now enough information
