Question

reference from: Merging Variable PHP

I have problem with $_POST getting blank null after click ‘submit’ button..

my code:

$temp_var = "_POST['text_".$id."']";

echo $$temp_var;

output: blank

Answer 1

First, did you make sure your form saves to the POST using method="post"?

Second of all, why’d you use variable variables?

You could simplify this to

echo $_POST["text_$id"];
