我在为我的应用程序创建某些东西时遇到问题。我已经拥有的是一个 CJuiTabs 系统，每个选项卡中都有一个表单。选项卡的数量和值/名称由我数据库中另一个表中的许多 tinyInt 列定义。选项卡的值作为隐藏字段与表单一起提交。
因此，现在如果您使用已提交记录的 id 访问视图，您将能够更新该记录，但无法使用其他选项卡值创建新记录。这是我的问题。我如何让应用程序根据您选择的选项卡决定是创建新记录还是更新现有记录？如果您正在更新一条记录，我希望显示该记录的值，但如果您正在创建一个新记录，您应该只看到空白字段（好吧，它是一个评级系统，所以我猜它是星号而不是字段）。
我想应该通过使用 AJAX 来完成，但我非常不确定如何做到这一点。
游戏/视图：
<?php
$tab_list=Platform::getPlatforms();
$tabarray=array();
// Create Dynamic Tabs
foreach($tab_list as $key=>$value){
$tabarray["$value"]=array(
'id'=>$key,
'content'=>$this->renderPartial('../ranking/_form',
array('model'=>$ranking, 'key'=>$key),TRUE)
);
}?>
<?php
