阅读更多

1. change the mysql table / fields to utf8_general_ci and add a line on preheader.php
mysql_query("SET NAMES utf8");
apply utf-8 for all relative php/js files.


2. add tinyMCE in php page.

3. remember to trigger the save function before submit on page ajaxCRUD.class.php function insertHeader and function makeAjaxEditor
tinyMCE.triggerSave();

4. decode the fields on function doAction

                        foreach($submitted_array as $field){
                            $submitted_values[] = urldecode($field);
                        }

5. encodeURIComponent on function makeAjaxEditor

        $return_html .= "" . $field_text . "
        
            
";

6. on file javascript_functions.js
change the charset
http_request.overrideMimeType('text/plain;charset=utf-8');

replace escape to encodeURIComponent for function getFormValues

			str += fobj.elements[i].name + "=" + encodeURIComponent(fobj.elements[i].value) + "&";

				var chkValue = encodeURIComponent(fobj.elements[i].value);

7. add to rss files - announcement_.php

	echo "		";
	echo "		";

8. summary
use javascript function encodeURIComponent but escape to encode value
use php function urldecode to decode value

// raw value
