Please help me with a simple question about TP2.0. I can't find any information online. Thank you!

I have been working on a tp2.0 website developed by the company in 2011 these days. In fact, I am relatively proficient in tp, but that refers to version 3.2. After I looked at the company website code, I felt sad. I found that I don’t even know how to do basic additions, deletions, modifications, and checks. I’ll post the source code and pictures and ask someone to help me figure out what I wrote wrong

Updated again, took screenshots of my website, the additions, deletions, modifications written by the developer, take a look at the bottom. Still not solved, does anyone have a version 2.0 project? Post it and take a look

First of all this is my add method code:
public function add(){
if(isPost){

<code>$model=M('Bcast');
$data['author']=$_POST['author'];
$data['title']=$_POST['title'];
$data['desc']=$_POST['desc'];
$data['url']=$_POST['url'];
$data['image']=$_POST['image'];
$model->data($data)->add();
$this->display();</code>

}
}
Such a simple piece of code killed me in version 2.0

1: I don’t know where to put $this->display();; after 3.2, I can write this else after not post, but I tried this version, and it can’t be displayed at all

Two: After I added, I originally planned to add success successfully, but after I added it, I clicked on the page and found that it directly showed success, without giving me a chance to fill in the form.

Okay, now let’s talk about the form

The above is written in my form. I created a page called BcastAction.class.php, and then created a new method in it. The inheritance is also written the same as other actions. The screenshot of the analysis is as follows

That’s all, I click
Submit

After

, it cannot be inserted into my Bcast table at all, and the fields are completely corresponding.

Masters, where did I go wrong with this question?

I tried to print, but as long as I print, the page will be the printed thing. I can't print it after submitting. If I don't write the display, I can't see the page at all

Thanks for the advice!

This should be added, it’s so damned written like this, I can’t understand it, it’s obviously assigning the category to the page, but I’m sure it was added this way, because I saw the link in the lower left corner

So I found another method that is more like inserting information, but what puzzles me is, why doesn’t it have a display? But I really can’t find this link

There is no link here, so there is no need to write a display? There is a link in add, so it must be displayed, but why does the add method not include any added code at all?
It’s so confusing to me

这个应该是添加，写成这样真是见鬼了，看不明白，这明显就是把分类assign到页面了，但我确定添加时是这个方法，因为我看左下角链接了

所以我找了另一个更像插入信息的方法，但让我疑惑的是，他咋没有display呢？不过我确实找不到这链接

他这个没链接，所以不需要写display吗？add有链接所以肯定要display的，可那add方法为什么压根没一句添加的代码啊？
费解死我了

我感觉你可以去翻翻thinkphp2.0的手册看看

<code>function add_info()
    {
        if(IS_POST)
        {
            $db= M();
            $db->create();
            $db->add();
            $this->success('添加成功',U('index'));
        }else{
            $this->display();
        }
    }</code>

如何，能否解决?

回楼上的，我就这么写的，这是在服务器上，没安装编辑器

链接那会，是照着原来网站写的

dislay的地方放对的话，蹦的页面是正常的

1.首先判断控制器方法是否接受到数据，可以echo或者var_dump看结果；
2.如果add方法不行，可以用原生的sql语句试试。

public function add(){

<code>echo '<pre class="brush:php;toolbar:false">';
var_dump($_POST);
die();
if(isPost){

    $model=M('Bcast');
    $data['author']=$_POST['author'];
    $data['title']=$_POST['title'];
    $data['desc']=$_POST['desc'];
    $data['url']=$_POST['url'];
    $data['image']=$_POST['image'];
       echo '<pre class="brush:php;toolbar:false">';
        var_dump($data);
        die();
    $model->data($data)->add();
    $this->display();
}</code>

}
上面你调两次试试
浏览器开f12,看看network,的返回值
你说插入了，然后字段都是空。为什么呢？这个明显就是你执行的add语句，没字段，或者字段被过滤，直接生成一条默认值的数组。
