Send data using POST method

I created an APP where I send data to my web page using POST method. I followed a lot of video explanation. My APP and also my web page are correct in their programs lines , even the response in my APP returns every thing perfect but my web page do not received anything, may there is a firewall in my hosting web page?

in APP i used: "set. web1.Url to" "correct web page direction"
then "call web1.PostText text" "number o text "

in web page I wrote (to debug)
echo '

';
print_r($_POST);
echo '
';

There is so much you have not told us or shown us, it is difficult to help.

  1. Blocks
  2. Receiving PHP file (I presume)
  3. Type of web hosting (paid/free)
  4. Any testing via POSTMAN or curl

First of all, thank you for your attention.

  1. I prepare some pictures of the block to send, I hope I done it well.
    I sent 3 pictures :
    number 1- is the real programation
    number 2 and 3 were test I made but all faillured

  2. the "function web" of app inventor use HTTP command, I supose my block are sending a POST command to my web page, this page is a PHP file. This program in this page works when i send POST between others pages of the same web page

  3. paid

  4. I have postman in my desk top but I didn't used it. I believe I need only to dowload the ".apk" file in my mobile (android) and test the blocks with my web page

Unfortunately, no images uploaded

true...I discovered it after answer you. I also received an email , I answer it with attaching the pictures but it also didn't works.....anyway...thank you for your attention
