Question

面对这样一个错误“语法错误，意外的T_CONSTANT_ENCAPSED_STRING”我理解带引号的东西而那只是没有被访问不是什么不起作用可能是什么问题

if (!session_admin ())
  {
    @header ('Location: ' . $CONFIG['SITE_URL']);
  }

  if (($_POST['Action'] == 'Save' AND $_POST['submit']))
  {
    foreach ($_POST as $key => $value)
    {
  --->    if ((($key != 'submit' AND $key != 'Action') AND $key != 'selectedtab') AND !isset ('key'))
      {
        if ((($key == 'SITE_TEMPLATE' AND $value != $CONFIG['SITE_TEMPLATE']) AND !$recache))
        {
          $recache = true;
        }

        $SQL = 'UPDATE ' . $_settings . ' SET value=\'' . $value . '\' WHERE setting=\'' . $key . '\'';

      }

      $$fieldname = trim ($value);
    }

    $Success[] = 'Site settings updated successfully.';
    if ($recache)
    {
      @header ('Location: ' . @get_link ($cur_page . '?recache=true'));
    }
    else
    {
      if ((!$Error AND $CONFIG['caching_status']))
      {
        empty_cache_folder ();
      }
    }
  }

以下内容无效

!isset ('key'))

将其替换为

!isset($key))

我还整理了你的代码，使其更具可读性。

<?php

if (!session_admin()) {
    //Try not to suppress errors, but handle them instead
    @header('Location: ' . $CONFIG['SITE_URL']);
    exit; //Always kill the script after issuing a header('Location
}

if (($_POST['Action'] == 'Save' AND $_POST['submit'])) {
    foreach ($_POST as $key => $value) {
        if ((($key != 'submit' AND $key != 'Action') AND $key != 'selectedtab') AND !isset($key)) {
            if ((($key == 'SITE_TEMPLATE' AND $value != $CONFIG['SITE_TEMPLATE']) AND !$recache)) {
                $recache = true;
            }

            $SQL = 'UPDATE ' . $_settings . ' SET value=\'' . $value . '\' WHERE setting=\'' . $key . '\'';
        }

        $fieldname = trim($value);
    }

    $Success[] = 'Site settings updated successfully.';
    if ($recache) {
        //Try not to suppress errors, but handle them instead.
        @header('Location: ' . @get_link($cur_page . '?recache=true'));
        exit; //Always kill the script after issuing a header('Location
    } else {
        if ((!$Error AND $CONFIG['caching_status'])) {
            empty_cache_folder();
        }
    }
}

语法错误，意外T_CONSTANT_ENCAPSED_STRING
