Please upload here a copy of your formatted php file. You possibly have an issue @ line 20.
(to upload add a .txt after filename.php)
You also have an issue with your mysql table:
nombre and email should be "varchar" and not "int" because they are strings. telefono may also need to be a "varchar" if numbers start with 0 or contain "+" signs.
so what is my error?. use the post text in process block?. no need to complete the empty spaces with %20?. i am a little confuse because i am following the steps from the link kio4
ok thanks but my head dont understand the error of the link kio4 about why the other is wrong could you can explain me. i know the solution but i like learn my errors to try to fix.
