PHP - what is wrong here? -

-

i'm making car rental system in school , have run issue cannot fix.

when have completed query ask cars matching users search have buttun can click rent car , redirects them page. lets want rent ferrari f12 , click on rent. when other page says "rent opel corsa" no matter car choose. silly oversight on side.

here search function

    function søk(){     define('db_host', 'db-kurs.hit.no'); define('db_name', 'v15gdb1'); define('db_user','v15g1'); define('db_password','pw1');   $con=mysql_connect(db_host,db_user,db_password) or die("kunne ikke koble til mysql: " . mysql_error());   $db=mysql_select_db(db_name,$con) or die("kunne ikke koble til mysql: " . mysql_error());   $sql =  mysql_query("select * biler  sted= '$_post[by]' , merke = '$_post[biler]'");  $resultat = $sql;  $mld = "du har valgt å søke etter en <b>$_post[biler]</b> <b>$_post[by]</b>.";   if ($_post['by'] == 'alle'){      $sql =  mysql_query("select * biler merke = '$_post[biler]'");       $resultat = $sql;       $mld = "du har valgt å søke etter en <b>$_post[biler]</b> <b>alle</b> byer.";  }    if ($_post['biler'] == 'alle'){      $sql =  mysql_query("select * biler sted= '$_post[by]' ");       $resultat = $sql;       $mld = "du har valgt å søke etter <b>alle</b> bilene <b>$_post[by]</b>.";  }      if ($_post['by'] == 'alle' , $_post['biler'] == 'alle'){      $sql =  mysql_query("select * biler");       $resultat = $sql;       $mld = "du har valgt å søke etter <b>alle</b> bilene <b>alle</b> byene.";  }     echo "<div id='søkmld'>$mld husk @ du må logge inn å leie en bil.</div>";   while($row = mysql_fetch_array($resultat, mysql_assoc))  {    $merke = $_session['merke'] = $row['merke'];   $modell = $_session['modell'] = $row['modell'];   $reg = $row['regnr'];   $pris = $row['dagspris'];   $sted = $row['sted'];   $status = $row['erledig'];   $bilde = $row['bilde'];    $_session['name'] = $merke. " " .$modell;      echo"   <div id='bilsøk'>    <div id='biltype'><h3> $merke $modell</div>    <div id='lei'>    <form method='post' action='leibil.php' name='leibil'>";    if(isset($_session['brukerid'])){     echo"<input type='submit' value='lei nå' name='lei $merke $modell'>      </div>    <div id='bilsøktxt'>    <table>     <tr>         <td>regnr:</td>         <td>$reg</td>     </tr>     <tr>         <td>pris:</td>         <td>$pris</td>     </tr>     <tr>         <td>sted:</td>         <td>$sted</td>     </tr>     <tr>         <td>status:</td>         <td>";         if ($status == 1){         echo'ledig';}         if ($status == 0){         echo'utleid';}         echo "</td>     </tr>     </table>       </div>       <div id='søkimg'><center><img src='images/cars/$bilde.jpg'></center></div>     </div>   "; } }}

and here div on page redirected to:

<div id="hoved">     <?php     echo"<h1>lei $_session[name]</h1>"     ?>   <?php     status(); ?>      <hr/> </div>

the status() function set know.

@dbinns66 correct, inconsistent session , post variables , cause problems.

also, stab in dark here...

when do:

while($row = mysql_fetch_array($resultat, mysql_assoc))

what happens if have more 1 row?

lets query returns 2 rows. when do:

$merke = $_session['merke'] = $row['merke']; $modell = $_session['modell'] = $row['modell']; ... $_session['name'] = $merke. " " .$modell;

$_session['name'] contain make , model of car in last row of query (in case, row 2).

anyway...

to fix this, try adding:

... echo"<input type='submit' value='lei nå' name='lei $merke $modell'>       <input type='hidden' value='$merke $modell' name='makeandmodel'> ...

in redirected page (leibil.php):

<div id="hoved">     <?php     echo"<h1>lei " . $_post['makeandmodel'] . "</h1>"     ?> ...

close form in first echo statement:

...   <div id='søkimg'><center><img src='images/cars/$bilde.jpg'></center </div> </form> ...
