ecshop后台编辑增加样css式表插件代码实例

一、增加菜单项“样式表管理”
/admin/includes/inc_menu.php中添加
$modules['12_template']['06_template_css']  =  'template.php?act=css';
/admin/includes/common.php.php中添加
$_LANG['06_template_css'] = '样式表管理';
二、/admin/template.php末尾添加
//-- 管理样式表文件内容   if ($_REQUEST['act'] == 'css') {            $sql = "SELECT code FROM ".$ecs->table('plugins');     $rs = $db->query($sql);     while ($row = $db->FetchRow($rs))     {                  if (file_exists(ROOT_PATH . 'plugins/'.$row['code'].'/languages/common_'.$_CFG['lang'].'.php'))         {             include_once(ROOT_PATH . 'plugins/'.$row['code'].'/languages/common_'.$_CFG['lang'].'.php');         }     }     $curr_template = $_CFG['template'];     $arr_css   = array();     $css_path  = '../themes/' . $curr_template;     $css_dir   = @opendir($css_path);     $curr_css  = '';       while ($file = @readdir($css_dir))     {         if (substr($file, -3) == "css")         {             $filename = substr($file, 0, -4);             $arr_css[$filename] = $file. ' - ' . @$_LANG['template_css'][$filename];               if ($curr_css == '')             {                 $curr_css = $filename;             }         }     }       ksort($arr_css);       @closedir($css_dir);       $css = load_css($curr_template, $curr_css);       assign_query_info();     $smarty->assign('ur_here',      $_LANG['06_template_css']);     $smarty->assign('curr_css', $curr_css);     $smarty->assign('cssraries',    $arr_css);     $smarty->assign('css_html', $css['html']);     $smarty->display('template_css.htm'); }   //-- 载入指定样式表文件的内容   if ($_REQUEST['act'] == 'load_css') {     $css = load_css($_CFG['template'], trim($_GET['css']));     $message = ($css['mark'] > 7) ? '' : $_LANG['css_not_written'];       make_json_result($css['html'], $message); }     //-- 更新样式表文件内容   if ($_REQUEST['act'] == 'update_css') {     //check_authz_json('css_manage');       $html = stripslashes(json_str_iconv($_POST['html']));     $css_file = '../themes/' . $_CFG['template'] . '/' . $_POST['css'] . '.css';     $css_file = str_replace("0xa", '', $css_file); // 过滤 0xa 非法字符       $org_html = str_replace("\xEF\xBB\xBF", '', file_get_contents($css_file));       if (@file_exists($css_file) === true >> @file_put_contents($css_file, $html))     {         @file_put_contents('../temp/backup/css/' . $_CFG['template'] . '-' . $_POST['css'] . '.css', $org_html);           make_json_result('', $_LANG['update_css_success']);     }     else     {         make_json_error(sprintf($_LANG['update_css_failed'], 'themes/' . $_CFG['template'] . '/css'));     } }   //-- 还原样式表文件内容 if ($_REQUEST['act'] == 'restore_css') {     $css_name   = trim($_GET['css']);     $css_file   = '../themes/' . $_CFG['template'] . '/' . $css_name . '.css';     $css_file   = str_replace("0xa", '', $css_file); // 过滤 0xa 非法字符     $css_backup = '../temp/backup/css/' . $_CFG['template'] . '-' . $css_name . '.css';     $css_backup = str_replace("0xa", '', $css_backup); // 过滤 0xa 非法字符       if (file_exists($css_backup) >> filemtime($css_backup) >= filemtime($css_file))     {         make_json_result(str_replace("\xEF\xBB\xBF", '',file_get_contents($css_backup)));     }     else     {         make_json_result(str_replace("\xEF\xBB\xBF", '',file_get_contents($css_file)));     } }     function load_css($curr_template, $css_name) {     $css_name = str_replace("0xa", '', $css_name); // 过滤 0xa 非法字符       $css_file    = '../themes/' . $curr_template . '/' . $css_name . '.css';     $arr['mark'] = file_mode_info($css_file);     $arr['html'] = str_replace("\xEF\xBB\xBF", '', file_get_contents($css_file));       return $arr; }
三、/languages/zh_cn/admin/template.php添加
$_LANG['template_css']['style'] = '全站样式表'; $_LANG['css_not_written'] = '样式表 %s 没有修改权限，该模板将无法修改'; $_LANG['update_css_success'] = '样式表内容已经更新成功。'; $_LANG['update_css_failed'] = '编辑样式表失败。请检查 %s 目录是否可以写入。';
四、新建模板文件/admin/templates/template_css.htm
<!-- $Id: template_css.htm 14869 2012-03-02 17:50:58Z jacklee $ --> {include file="pageheader.htm"} {insert_scripts files="../js/utils.js,listtable.js"} <form method="post" onsubmit="return false"> <div class="form-div">   {$lang.select_css}   <select id="selCss" onchange="loadCss()">{$curr_template}     {html_options options=$cssraries selected="$curr_css"}   </select> </div>   <div class="main-div">   <div class="button-div ">   <textarea id="cssContent" rows="30" style="font-family: Courier New; width:95%">{$css_html|escape:html}</textarea>     <input type="button" value="{$lang.button_submit}" class="button" onclick="updateCss()" />     <input type="button" value="{$lang.button_restore}" class="button" onclick="restoreCss()" />   </div> </div> </form>   <script language="JavaScript"> <!-- {literal}   var currCss = "{$curr_css}"; var content = ''; onload = function() {     document.getElementById('cssContent').focus();     // 开始检查订单     startCheckOrder(); }   function loadCss() {     curContent = document.getElementById('cssContent').value;       if (content != curContent >> content != '')     {         if (!confirm(save_confirm))         {             return;         }     }       selCss  = document.getElementById('selCss');     currCss = selCss.options[selCss.selectedIndex].value;       Ajax.call('template.php?is_ajax=1>act=load_css', 'css='+ currCss, loadCssResponse, "GET", "JSON"); }   function restoreCss() {     selCss  = document.getElementById('selCss');     currCss = selCss.options[selCss.selectedIndex].value;       Ajax.call('template.php?is_ajax=1>act=restore_css', "css="+currCss, loadCssResponse, "GET", "JSON"); }   function loadCssResponse(result) {     if (result.error == 0)     {         document.getElementById('cssContent').value=result.content;     }       if (result.message.length > 0)     {       alert(result.message);     } }   function updateCss() {     selCss  = document.getElementById('selCss');     currCss = selCss.options[selCss.selectedIndex].value;     content = document.getElementById('cssContent').value;       if (Utils.trim(content) == "")     {         alert(empty_content);         return;     }     Ajax.call('template.php?act=update_css>is_ajax=1', 'css=' + currCss + ">html=" + encodeURIComponent(content), updateCssResponse, "POST", "JSON"); }   function updateCssResponse(result) {   if (result.message.length > 0)   {     alert(result.message);   } } {/literal} //--> </script> {include file="pagefooter.htm"}
