php - Issue with retrieving some values out of my Database -

- 

<?php include 'session.php'; ?>  <html> <head> <link href="css/adminopmaak.css" rel="stylesheet" type="text/css"/> <?php         mysql_connect("localhost", "admin", "") or die(mysql_error());         mysql_select_db("test") or die(mysql_error()); ?>  </head>  <body> <div class = "header">  <a href="index.php"><img src="home-icon.png" width="25" height ="25"></a>  </div> <!--header-->  <div class = "menu">  </div> <!--menu-->  <div class ="content"> <form action="login.php" method="post">  <input type="text" align="center" name="account"  value="<?php echo isset     ($_post['account'])?$_post['account']:"";?>"/> <br /> <input type="text" align="center" name="password" value="<?php echo isset    ($_post['password'])?$_post['password']:"";?>" /><br />     <input type="submit" name="login" value="login"/><br /> <?php  if(isset ($_post ['login'])) {     $querystring ="select account admins account ='".$_post['account']."';";     $result = mysql_query($querystring);      mysql_query($querystring)or die (mysql_error());      if (empty($_post['account']) || empty($_post['password']))      {         echo "niet alles ingevoerd";       }     elseif (mysql_num_rows($result) == 1)      {         $user = mysql_fetch_assoc($result);      }      else      {         echo "dit account bestaat niet";     }      if(md5($_post['password']) != $user['password'])     {         echo "wachtwoord niet correct";?><br/> <?php         echo "het account is:".$user['account'];?><br/> <?php         echo "het wachtwoord is: ".$user['password'];?><br/> <?php         echo mysql_fetch_assoc($result);     } }    ?>   </form> </div>  </body> </html>

it's kinda strange since recognize $user['account']; , doesnt recognize password version.

my database has right values. echo's:

wachtwoord niet correct het account is:probeersel het wachtwoord is:

so dont know why recognize account doesn't recognize wachtwoord. why that?

there few problems.

first, mysql statement wrong.

change this:

$querystring ="select account admins account ='".$_post['account']."';";

to this:

$querystring ="select * admins account ='" .$_post['account']. "'";

next, 1 test, echo out account name , password db query, can make sure getting expect (perhaps capitalization wrong field name or that).

$user = mysql_fetch_assoc($result); echo 'got username: ' .$user['account']. '<br />'; echo 'got password: ' .$user['password']. '<br />';

once have confidence getting correct data, can finish script.

this:

if(md5($_post['password']) != $user['password']) {     echo "wachtwoord niet correct";?><br/> <?php     echo "het account is:".$user['account'];?><br/> <?php     echo "het wachtwoord is: ".$user['password'];?><br/> <?php     echo mysql_fetch_assoc($result); }

can re-written as:

if(md5($_post['password']) != $user['password']) {     echo "wachtwoord niet correct<br />";     echo "het account is: " .$user['account']. "<br />";     echo "het wachtwoord is: " .$user['password']. "<br />"; }
