Question

I have a php variable “echo $id”. Now I want to use the $_POST method to post the variable. I just want to know how to do this for a variable because $_POST[$id] does not work?

Answer 1

With the method $_POST you must be posting to something.

My suggestion to you is to create a form, then have the form going to the file you wish to post to:

So something like this:

echo '<form action  = "fileToPostTo.php" method = "post">
<input type = "text" hidden value = "'.$id.'" />
</form>';

And then submit the form when the document loads through jquery or javascript.
