Get $Post in PHP with Dot in the name

Question

This should be a very basic question in PHP, but I couldn't get a nice solution in web. Please some experts show me with example.

I am trying to read value of 3 textboxes, those names are input_38.1, input_38.2, input_38.3

so my code is echo $_POST['input_38.1']. But it doesn't print the 1st textbox's value. What is the way to get all three textbox's values.

Thanks in advance.

Answer 1

I am trying to read value of 3 textboxes, those names are input_38.1, input_38.2, input_38.3

From the PHP Manual:

Dots and spaces in variable names are converted to underscores. For example <input name="a.b" /> becomes $_REQUEST["a_b"].

So, you'd need to write:

echo $_POST['input_38_1'];

To avoid confusion, it's a good idea not to use dots in your form's name attributes.

Answer 2

You need to change your echo statement:

$_POST['input_38_1'];

I usually stay away from using dots in my variable names.
