在循环中将两个表单字段一起插入[关闭]

Question

I have two form fields "First name" and "Last name" I can also clone the two fields to add more users on one submit. I want each record to have it's own ID once inserted into the database. However I can't seen to get it to insert two values at once in a loop.

My form fields are

 <input type="text" name="firstname_0" size="35" value="" />
 <input type="text" name="lastname_0" size="35" value="" />

The name auto increments every time I want to add another user firstname_1, lastname_1 etc...

I would like to add 1 or unlimited users in one form submit.

Any help would be appreciated.

I tried using a foreach() and while but can't get the concept.

Answer 1

Use arrays in the inputs' name attribute.

<input type="text" name="users[0]['firstname']" size="35" value="" />
<input type="text" name="users[0]['lastname']" size="35" value="" />

<input type="text" name="users[1]['firstname']" size="35" value="" />
<input type="text" name="users[1]['lastname']" size="35" value="" />

And then:

foreach ($_POST['users'] as $user) {
}
