在窗体中显示mysql复选框值(Display mysql checkbox value in form)

一个简单的问题,但我似乎无法找到答案。

我有一个简单的表单,当选中复选框时,将值“on”插入数据库

当重新访问表单并显示数据库信息时,如何从数据库中提取数据时检查复选框?

我试过这个,但它不起作用

<input type="checkbox" name="positioning" class="input_margin" value="<? $row['positioning']; ?>">Positioning<br />

(我只需要帮助,我有sql查询等设置好)

谢谢


A simple question but I can't seem to find the answer.

I have a simple form that inserts the value 'on' to a database when a checkbox is checked

How do I get the checkbox checked when the data is pulled from the database when the form is revisited and displaying with the database information?

I have tried this but it doesn't work

<input type="checkbox" name="positioning" class="input_margin" value="<? $row['positioning']; ?>">Positioning<br />

(I only need help with this, I have the sql query etc set up fine)

Thanks

你显然索引时间/ 1000

1454256000/1000 = 1454256 -> Sat, 17 Jan 1970 19:57:36 GMT
1454342400/1000 = 1454342 -> Sat, 17 Jan 1970 19:59:02 GMT

这就是为什么他们都属于同一个桶1970-01-17T19:55:00.000Z ,与您的日期间隔/ 1000相对应


You are apparently indexing time / 1000

1454256000/1000 = 1454256 -> Sat, 17 Jan 1970 19:57:36 GMT
1454342400/1000 = 1454342 -> Sat, 17 Jan 1970 19:59:02 GMT

that is why they all fall within the same bucket 1970-01-17T19:55:00.000Z, corrisponding with your date interval / 1000
