php - scope of $_POST[] , trying to access $_POST[] variable, getting the undefined index error -


i have these 2 forms submits different blocks of same script. unable access variable of 1 block in other, though both variables in same script.

html form :(1.php)

<html>   <form method="post" action="2.php" enctype="multipart/form-data">     </br>     choose user name:</font>     <input type="text" name="username">     <input type="submit" name="submit" value="save , proceed">   </form> </html>

2.php:

 <?php     $name=$_post['username'];     if ((isset($_post['username'])) && ($_post['submit'] == 'save , proceed'))     {         $name=$_post['username'];         echo $name;         if($name=='azra')         {         ?>         <html>           <form method="post" action="2.php" enctype="multipart/form-data"></br>             enter age:</font>             <input type="text" name="age">             <input type="submit"  name="submit" value="done">           </form>         </html>         <?php         }     }      if((isset($_post['age'])) && ($_post['submit'] == 'done'))     {         $age=$_post['age'];         echo $age;         if($age==25)         {             echo "hi" .$name;             echo "your age ". $age;             echo"you eligible";         }     }       ?>

how access $_post['username'] in code following html form in same script? thank in advance.

if understand want pass username twice. can use hidden input, not visible (only transports data):

<input type="hidden" name="username" value="<?php echo $_post['username']; ?>" />
