Answer 1

Thanks to all who answered my question!!!

Answer 2

So it seems the problem cannot be resolved

Answer 3

I've corrected action ="" and empty display is appeared because in the form I filled in wrong url address above .

That 's why I wrote www.sololearn. com/Playground /form_val. php
but empty display is appeared again.

Answer 4

in http://www.example.com /test_form. php

Answer 5

I can't find and see test_form. php

Answer 6

I've corrected errors but the problem exists.

Answer 7

No, I Cannot verify if $_SERVER ["REQUEST_METHOD"] is available on my server.

Answer 8

Yes, I try this code Work on another server.

Answer 9

I don't know.I suppose it is a verification with "if" loops may be.

Answer 10

Answer 12

EGO
Code Playground doesn't support form submission, you cannot test form submission code in Code Playground. You have to use local host, or (as you said before) try in your own server.

Answer 13

where does "test_form.php" exist?

Answer 14

test_form.php has to exist in the same directory or provide a path to it, so when you click on submit it gets executed to process the data.

Answer 15

action = ".../test_form.php"

This doesn't look like a valid relative path. A triple dot in the beginning of the path string disqualifies the path.

The PHP script block starting at line 49 begins with <? only.

Answer 16

A note from

http://php.net/manual/en/reserved.variables.server.php

Says that there are no guarantee that elements of $_SERVER are always similarly available between systems. It says it depends on web server. Can you verify $_SERVER["REQUEST_METHOD"] was available for your server?

Answer 17

I guess in this case we're stuck with checking whether if `isset($_POST["submit"])` check yields true. Upon which we can *assume* a submission is there for us to work with. But I once read somewhere that such approach is not considered as good practice.

Answer 18

Ipang the issue with his code is, the action of the submit button is to execute test_form.php, and it does not exist. the php code is supposed to be in that file. here he has everything in one page (file)
EGO are you trying to make this work on an other server or just SoloLearn playground?

Answer 19

Bahha🐧
I thought so too, but earlier he said it's in http://www.example.com/test_form.php. So I thought of other possibilities (invalid path and $_SERVER["REQUEST_METHOD"])

Answer 20

EGO @eg what's the code inside test_form.php?
