PHP序列化许多输入

Question

I have this HTML form:

<form action="" method="post">
   <input type="hidden" name="data_first" value="9" />
   <input type="hidden" name="data_second" value="2" />
   <input type="hidden" name="date" value="2018-01-25" />
   <input type="text" name="posted_data" value="0.1" />
</form>

I want combine this Posted data, with serialize function.

I can serialize only one input. example: serialize($_POST['posted_data']); I need function like this:

serialize($_POST['posted_data'],$_POST['data_first'],$_POST['data_second'],$_POST['date']);

Any ideas?

Answer 1

You can simply do -

serialize($_POST);

It will serialize all the posted data. And then process them accordingly.

Update

You can use input arrays -

<form action="" method="post">
   <input type="hidden" name="data[data_first]" value="9" />
   <input type="hidden" name="data[data_second]" value="2" />
   <input type="hidden" name="data[date]" value="2018-01-25" />
   <input type="text" name="data[posted_data]" value="0.1" />
</form>

And

serialize($_POST['data']);

Will serialize those specific inputs present in data.
