PHP会话问题

Question

I'm using sessions to save what ever the user types in the form and what ever they do type will be displayed on the other pages.

It was working perfectly fine but after all the server uploads and such my code has completely done one on me and i'm lost.

Can somebody see if they can spot a mistake? I need fresh eyes.

HTML.

    <div id="form"><!--Form Start-->

<form action="home.php" method="post">

    <p>Enter Name <input type="text" id="full_name" name="fullName"    class="name_input"/>

<input type="submit" name="submit"  value="Submit" />

</p>

    </form>

    </div><!--Form end-->

PHP.

    <?php
session_start(); // declaring the variable

if(isset($_POST['fullName'])){ //setting the variable 

    if(empty($_POST['fullName'])){ //if empty dont to nothing but my wep page will reload

    }else{ //if they have do this

        $_SESSION['fullName'] = $_POST['fullName']; //get the session for the name (From the from)


        header("Location: home.php"); //then will direct the user to the home page (will also display name on each page)
    }}
    ?>

Session on other pages

                  <div id="echo"> <!-- div ECHO start -->           
                                  <?php


                   echo $_SESSION['fullName']
             ?>                  
            </div>  <!--div ECHO end -->    

Answer 1

You need to start session on other page as well and stop the script from setting that session. After header location you need to use exit here.

 <?php session_start();?>
  <div id="echo"> <!-- div ECHO start -->           
  <?php
     echo $_SESSION['fullName'];
   ?>      

you need use exit after header location :-

 header('location: home.php');
 exit;
