php - Showing different content based on $_SESSION UserLevel -


i having problem trying show different menu options based on userlevel. have mysql database users table. users table contains userlevel either set 0 or 1. reason php isn't working. in fact, when add php menu, not display on site below menu. advice appreciated.

code starts session

<?php   if(!empty($_session['loggedin']) && !empty($_session['username']))   {     ?>  <?php include "mainnav.php"; ?>     <center>      <h2> campaign updates</h2>  </center>  <div id="campaignpostwrap"> <div id="campaignscrollbox">  <?php $con=mysqli_connect("localhost","dorians","ds2953!b67p$","aldentec"); // check connection if (mysqli_connect_errno())   {   echo "failed connect mysql: " . mysqli_connect_error();   }  $result = mysqli_query($con,"select * campaigns order postdate desc");  while($row = mysqli_fetch_array($result))   {   echo "<div id='campaignpostcontainer'>";   echo "<ul class='campaignpostbox'>";   echo "<p class='postinfo'>";   echo "posted on:";   echo "<li>" . $row['postdate'] . "</li>";   echo "</p>";   echo "<p class='postinfo'>";   echo "posted by:";   echo "<li>" . $row['postname'] . "</li>";   echo "</p>";   echo "<li class='postentry'>" . $row['postentry'] . "</li>";   echo "</ul>";   echo "</div>";   echo "<hr>";   }   mysqli_close($con); ?>  </div> <?php include "campaignpost.php"; ?> </div>   <?php include "chat.php"; ?>    <?php }   elseif(!empty($_post['username']) && !empty($_post['password']))   { $username = mysql_real_escape_string($_post['username']);   $password = md5(mysql_real_escape_string($_post['password']));           $checklogin = mysql_query("select * users username = '".$username."' , password = '".$password."'");        if(mysql_num_rows($checklogin) == 1)       {           $row = mysql_fetch_array($checklogin);           $email = $row['emailaddress'];           $userlevel = $row['userlevel'];          $_session['username'] = $username;           $_session['emailaddress'] = $email;           $_session['loggedin'] = 1;         $_session['userlevel'] = $userlevel;            echo "<h1>success</h1>";           echo "<p>we redirecting member area. if not automatically redirected <a href='index.php'>click here</a></p>";           header( "refresh:10;url=index.php" );       }   else       {           echo "<h1>error</h1>";           echo "<p>sorry, account not found. please <a href=\"index.php\">click here try again</a>.</p>";       }   }   else   {       ?>

menu code isn't working

<?php session_start(); ?>  <?php  $userlevel = $_session['userlevel'];  if($userlevel == 0) {     echo "<ul class="mainnav">         <a href="characterroll.php"><li> create character</li></a>         <a href="questcreate.php"><li> create quest</li></a>         <a href="characterview.php"><li> view characters</li></a>         <a href="questlist.php"><li> view quests</li></a>         <a href="booksview.php"><li> book list</li></a>     </ul>";  } elseif($userlevel == 1) {      echo "<a href="dmtools.php"><li> dm tools</li></a>"; } ?>  <?php include "greeter.php"; ?>

your quotes undoubtedly problem here:

if($userlevel == 0) {     echo "<ul class="mainnav">         <a href="characterroll.php"><li> create character</li></a>         <a href="questcreate.php"><li> create quest</li></a>         <a href="characterview.php"><li> view characters</li></a>         <a href="questlist.php"><li> view quests</li></a>         <a href="booksview.php"><li> book list</li></a>     </ul>";  } elseif($userlevel == 1) {      echo "<a href="dmtools.php"><li> dm tools</li></a>"; }

notice syntax highlighting above shows issue in string. see how turns black when gets mainnav? that's because mainnav no longer part of string. that's bad thing here.

look @ first line of echo:

echo "<ul class="mainnav">

you open quote , close @ class=". now, it's trying evaluate mainnav constant or other language construct. on top of that, doesn't know mainnav haven't provided kind of operators.

instead, should like:

if($userlevel == 0) {     echo '<ul class="mainnav">         <a href="characterroll.php"><li> create character</li></a>         <a href="questcreate.php"><li> create quest</li></a>         <a href="characterview.php"><li> view characters</li></a>         <a href="questlist.php"><li> view quests</li></a>         <a href="booksview.php"><li> book list</li></a>     </ul>';  } elseif($userlevel == 1) {      echo '<a href="dmtools.php"><li> dm tools</li></a>'; }

alternatively, escape every location there non-string-terminating quote \".

another option use heredoc syntax.

identifier - Is it possible for an html5 document to have two ids? -

i wondering if html5 element can have 2 ids, this: <button id="thing1" id="thing2" name="button1" onclick="change()">click here</button> or this: <button id="thing1, thing2" name="button1" onclick="change()">click here</button> also, if 1 of ids said 1 thing, , other id said thing, 1 used? tl;dr : no. in versions of html, each element can have 1 id. see the spec : the id attribute specifies element's unique identifier (id). [dom] the value must unique amongst ids in element's home subtree , must contain @ least 1 character. the value must not contain space characters. note: there no other restrictions on form id can take; in particular, ids can consist of digits, start digit, start underscore, consist of punctuation , etc. note: element's unique identifier can used variety of purposes, notably way link specific parts of document usin
