php - Framework7 not passing URL variable to next page -

i can't framework7 use url variable ?username=user1 on next page.

it generated , assigned link on page 1 doesn't used in either sql query or echo statements on page 2.

page 1 sets variable in hyperlink with;

profile.php?username=<?php echo htmlentities($row['username'], ent_quotes, 'utf-8'); ?> 

page 2 'gets' variable using;

<?php $username = (isset($_get['username']))? trim(strip_tags($_get['username'])) : ""; ?> 

framework7 web application framework - www.idangero.us/framework7/.

edited add full source of profile.php use variable.

<?php       // first execute our common code connection database , start session      require("common.php");       // @ top of page check see whether user logged in or not      if(empty($_session['user']))      {          // if not, redirect them login page.          header("location: index.php");           // remember die statement absolutely critical.  without it,          // people can view members-only content without logging in.          die("redirecting index.php");      }       // below point in file secured login system         // can retrieve list of members database using select query.      // in case not have clause because want select      // of rows database table.      $query = "          select              id,             username,             email         users username = '$username'     ";       try      {          // these 2 statements run query against database table.          $stmt = $db->prepare($query);          $stmt->execute();      }      catch(pdoexception $ex)      {          // note: on production website, should not output $ex->getmessage().          // may provide attacker helpful information code.           die("failed run query: " . $ex->getmessage());      }       // finally, can retrieve of found rows array using fetchall      $rows = $stmt->fetchall();  ?>   <?php include('header.php') ?>  <div class="pages navbar-through toolbar-through"> <div class="page" data-page="profile">  <div class="page-content">  <div class="content-block"> <div class="content-block-inner">  <?php  print_r($_get); ?>  <p>profile content go here - <?php echo '&username'; ?></p> <?php foreach($rows $row): ?>    <div>username: <?php echo $row['username'] ?></div>    <div>location: <?php echo $row['email'] ?></div>  <?php endforeach; ?>  <a href="private.php">go back</a><br /> </div>  </div> </div>  </div> </div>  <?php include('footer.php') ?> 

i have printed $get variables , can see variable value passed - not being used in query reason.

you have not assigned $username variable should use this:

<?php       // first execute our common code connection database , start session      require("common.php");       // @ top of page check see whether user logged in or not      if(empty($_session['user']))      {          // if not, redirect them login page.          header("location: index.php");           // remember die statement absolutely critical.  without it,          // people can view members-only content without logging in.          die("redirecting index.php");      }       // below point in file secured login system         // can retrieve list of members database using select query.      // in case not have clause because want select      // of rows database table.      $username = (isset($_get['username']))? trim(strip_tags($_get['username'])) : "";      $query = "          select              id,             username,             email         users username = '$username'     ";       try      {          // these 2 statements run query against database table.          $stmt = $db->prepare($query);          $stmt->execute();      }      catch(pdoexception $ex)      {          // note: on production website, should not output $ex->getmessage().          // may provide attacker helpful information code.           die("failed run query: " . $ex->getmessage());      }       // finally, can retrieve of found rows array using fetchall      $rows = $stmt->fetchall();  ?>   <?php include('header.php') ?>  <div class="pages navbar-through toolbar-through"> <div class="page" data-page="profile">  <div class="page-content">  <div class="content-block"> <div class="content-block-inner">  <?php  print_r($_get); ?>  <p>profile content go here - <?php echo $username; ?></p> <?php foreach($rows $row): ?>    <div>username: <?php echo $row['username'] ?></div>    <div>location: <?php echo $row['email'] ?></div>  <?php endforeach; ?>  <a href="private.php">go back</a><br /> </div>  </div> </div>  </div> </div>  <?php include('footer.php') ?> 

you should escape input's prior going db
