recently viewed page “you haven't viewed a page yet”

Question

I have some code to show the pages you have recently viewed on my website but if you haven't viewed a page yet i get an error which is

Notice: Undefined index: pageurl in C:\xampp\htdocs\project1\recent.php on line 97

Warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\project1\recent.php on line 97

I need it to say you haven't viewed a page yet instead of getting this error here's the code i have at the moment

<?php

foreach( $_SESSION['pageurl'] as $key=>$value) {
echo '<a href="'.$value.'">Click here </a>';
echo 'to see last page which is '."'localhost".$value."'".' <br />';
}
?>

any ideas?

Answer 1

if(isset($_SESSION['pageurl']))
  foreach( $_SESSION['pageurl'] as $key=>$value) {
  echo '<a href="'.$value.'">Click here </a>';
  echo 'to see last page which is '."'localhost".$value."'".' <br />';
  }

Answer 2

Add session_start before you check for session

if (!isset($_SESSION))
 session_start ();

if (isset($_SESSION['pageurl'])) { 
  foreach( $_SESSION['pageurl'] as $key=>$value) {
      echo '<a href="'.$value.'">Click here </a>';
      echo 'to see last page which is '."'localhost".$value."'".' <br />';
  }
} else {
    echo "You haven't viewed a page yet";
}

Hope this helps :)

You should check if pageurl is set and is it an array before starting foreach.

<?php
if(isset($_SESSION['pageurl']) && is_array($_SESSION['pageurl']))
    foreach( $_SESSION['pageurl'] as $key=>$value) {
        echo '<a href="'.$value.'">Click here </a>';
        echo 'to see last page which is '."'localhost".$value."'".' <br />';
    }
?>
