PHP具有单个动作的多个表单

Question

I've multiple forms with a single action, a single php page that gets called by all the forms.

How can I differentiate which form was sent to the php page?

Answer 1

Using a different unique input type="hidden" for each form.

HTML:

<input type="hidden" name="form_id" value="1">
<input type="hidden" name="form_id" value="2">

PHP:

$myform = $_POST["form_id"];

You can also use the submit button but note that the "value" parameter is what gets displayed to the user so you won't be able to modify it (assuming you want the same text to be displayed on every button).

<input type="submit" name="action" value="the user saw this">

PHP:

$_POST["action"] // -> "the user saw this";
