求大神帮忙看看，怎么连等号都不识别？？

<?php
require_once '../connect.php';
if (!(isset($_POST['title'])&&(!empty($_empty['title'])))){
echo "<script>alert('标题不能为空');window.location.href = 'article.add.php';</script>";
}
$title = $_POST['title'];
$author = $_POST['author'];
$description = $_POST['description'];
$content = $_POST['content'];
$dateline = time();
$insertsql = "insert into article(title, author, description, content, dateline)values('$title','$author','description','content','$dataline');
if(mysql_query($insertsql)){
echo "<script>alert('标题不能为空'); window.location.href = 'article.add.php';</script>"; //此处等号报错意外
}else {
echo "<script>alert('标题不能为空'); window.location.href = 'article.manage.php';</script>";
}
?>
报错：syntax error, unexpected '='
