/**
|
|
* Text Editor Main Class
|
|
*
|
|
* This class contains all the main class functions
|
|
* EXAMPLE USAGE
|
|
* <code>
|
|
* $han_editor = new han_editor();
|
|
* $han_editor->ipsclass =& $this->ipsclass;
|
|
* $han_editor->init();
|
|
*
|
|
* # To generate the HTML for the editor:
|
|
* $editor_html = $han_editor->show_editor( $raw_post, 'Post' );
|
|
*
|
|
* # $raw_post is either raw HTML for the rich text editor or raw BBCode tagged text when
|
|
* # using the standard editor. (See the document on the BBCode parser for more information)
|
|
* # 'Post' is the name of the form field you wish use. In this case it'll return $_POST['Post'].
|
|
*
|
|
* #To process the editor's text into tagged BBCode text:
|
|
* $post = $han_editor->process_raw_post( 'Post' );
|
|
*
|
|
* #'Post' is the name of the form field you used when displaying the editor. As in $_POST['Post']
|
|
*
|
|
* # To use the HTML generated by editor class for displaying the actual editor (in our example; $editor_html)
|
|
* # you'll need to use it like this:
|
|
*
|
|
* <form id='postingform' onsubmit='return ValidateForm()' action="$url" method="post" name="REPLIER">
|
|
* {$editor_html}
|
|
* <br /><input type="submit" value="Post" /></div>
|
|
* </form>
|
|
*
|
|
* The form tag MUST have: id='postingform' onsubmit='return ValidateForm()' otherwise the editor will fail.
