我正在尝试保存到数据库,如果它已经在数据库中,我希望忽略该帖子。这就是我目前保存它的方式。的postid必须是唯一的。
public function save($type, $postid, $url, $author, $content)
{
$post = new Post;
$post->type = $type;
$post->postid = $postid;
$post->url = $url;
$post->author = $author;
$post->content = $content;
echo $post;
$post->save();
}

在尝试保存之前,对您希望唯一的任何字段使用Validator类的unique验证规则。
$input = array('postid' => $postid);
$rules = array(
'postid' => 'unique:posts,postid'
);
$validate = Validator::make($input,$rules);
if($validator->passes())
{
$this->save($type, $postid, $url, $author, $content)
}
else
{
$messages = $validator->messages();
echo $messages->first('postid');
}
