我已经四处走动了,我似乎无法得到我想要的逻辑。
以下是代码:
function fetchFile() {
global $directory;
if (isset($_GET['id'])) {
global $sampleIssue,$freeIssue;
$id = mysql_real_escape_string($_GET['id']);
$result = mysql_query("SELECT `volume`,`number`,`EditorMessage` FROM `articles` WHERE `id`='$id';");
$article = mysql_fetch_assoc($result);
if
(($article['volume']!=$sampleIssue['vol'] || $article['number']!=$sampleIssue['no']) || ($article['EditorMessage']==='N')
&& ($article['volume']!=$freeIssue['vol'] || $article['number']!=$freeIssue['no'])){
global $needsLogin;
$needsLogin = TRUE;
}
基本上我需要登录为真或满足以下三个条件中的任何一个:
$article['volume']!=$sampleIssue['vol'] || $article['number']!=$sampleIssue['no']
OR
$article['EditorMessage']==='N'
OR
$article['volume']!=$freeIssue['vol'] || $article['number']!=$freeIssue['no']
我也尝试过开关盒,我只是没有得到它。
