fix arabic cross_site_rss with ajaxcrud

詳細
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.

	
	

	
        tinyMCE.init({
			mode : "textareas",
			theme : "advanced",
			gecko_spellcheck : true,
			remove_linebreaks : true,
			width : "640",
			plugins : "table,advimage,advlink,emotions,iespell,insertdatetime,preview,searchreplace,xhtmlxtras,media,directionality",
			theme_advanced_buttons1 : "justifyleft,ltr,|,justifyright,rtl,|,justifycenter",
			theme_advanced_buttons2 : "bold,italic,underline,strikethrough,|,fontsizeselect,forecolor,backcolor,|,sub,sup",
			theme_advanced_buttons3 : "cut,copy,paste,pastetext,pasteword,removeformat,|,bullist,numlist,|,outdent,indent,|,undo,redo,|,preview",
			theme_advanced_disable : "charmap",
			theme_advanced_toolbar_location : "top",
			theme_advanced_toolbar_align : "left",
			theme_advanced_path_location : "bottom"
			});
	

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 "
