如何不将提交按钮值存储为发布数据php

Question

ok i have dynamically created form elements with unique names and when validated i want to store all the form data into SESSION. This is the code to do it:

if(isset($_POST["address_submit"])){
  insertSessionVars();
  header("Location: http://localhost/project%20gallery/notes.php");
  exit;
}

function insertSessionVars(){
  foreach($_POST as $fieldname => $fieldvalue){
    $_SESSION['formAddresses'][$fieldname] = $fieldvalue;
  }
}

This works almost fine but stores also submit button value. I output it like this:

foreach($_SESSION['formAddresses'] as $value){

    echo $value;

}

Any help will be greatful :)

Don't assign a name attribute to your submit button. If you assign a name then it is passed as part of the $_POST array.

<input type="submit" value="My Button" />

Since you no longer have the submit button in post, instead of checking if the submit button is set check to see if the post array contains data using count().

if(count($_POST) > 0)
