php - SQL Query succeeds but no information -


okay code works pretty far, goes through, problem when try , print unordered list , it's contents nothing. when view source code have <ul> </ul>. there's space, surely happening.

this code, have commented what's happening obvious:

$uname = mysqli_real_escape_string($link, $_session['username']); //get username ready $sql = mysqli_query($link, "select * users username = '" . $uname . "'"); //sql query result      if(!$sql)         {         echo "error retrieving user id. please try again. mysql error: " . mysqli_error($link);         }     elseif($row = mysqli_fetch_assoc($sql))         {             $uid = $row['userid']; //obtain userid         }     else         {         echo "error: " . mysqli_error($link) . "<br />" . $uname . " / " . $sql . " / " . $uid;         }      mysqli_free_result($sql);      $sql = mysqli_query($link, "select * auditions"); //get auditions table      if(!$sql)         {         echo "error retrieving auditions. please try again later. error: " . mysqli_error($link);         }     elseif($row = mysqli_fetch_assoc($sql))         {         if(mysqli_num_rows($sql)==0)             {             echo "sorry, there no open auditions. please try @ later date.";             }         else             {             echo "<ul>";             while($row = mysqli_fetch_assoc($sql))                 {                 echo "<li><a href='auditions.php?id=" . $row['audid'] . "'>" . $row['audname'] . "</a></li>";                 }             echo "</ul>";             }         }     else         {         echo "error: " . mysqli_error($link);         }

where going wrong? thing doesn't pick results , i've put data table there entries! otherwise there aren't any. i've reversed shows message if there aren't 0 entries , works. doing wrong guys?

thanks in advance.

you fetching result twice. instead, fetch result in while loop:

<?php $sql = mysqli_query($link, "select * auditions"); //get auditions table      if(!$sql)         {             echo "error retrieving auditions. please try again later. error: " . mysqli_error($link);         }         else{             if(mysqli_num_rows($sql)==0)             {                 echo "sorry, there no open auditions. please try @ later date.";             }             else             {                 echo "<ul>";                 while($row = mysqli_fetch_assoc($sql))                 {                     echo "<li><a href='auditions.php?id=" . $row['audid'] . "'>" . $row['audname'] . "</a></li>";                 }                 echo "</ul>";             }         }  ?>

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
