php - display database field in textbox -

-

i trying display database input in textbox editing. cant seem working?! page links forum post edit button. firstly, don't know how database info particular field displayed , don't understand how make sure post user clicks edit post displayed.

my code looks this

<?php #data preparation query  $id=$_get['id'];   # selects title , description fields database  $sql = "select a_answer $tbl_name question_id='$id'";  $result=mysql_query($sql); $rows=mysql_fetch_array($result);  ?>  <h3>edit</h3> <form action="save_edit.php" enctype="multipart/form-data" method="post" name="myform" />    <table>       <tr>        <td><b>answer</b></td>        <td><textarea cols="80%" rows="10" name="a_answer"><?php echo $row['$a_answer']; ?></textarea></td>      </tr>      </table>   <input name="id" type="hidden" value="<? echo $id; ?>">       <input name="enter" type="submit" value="edit"> </form>      <?php mysql_close(); ?>

two errors in code: firstly, using row instead of rows. second dollar sign 're using when accessing field. code below should work, provided database query correct.

<?php #data preparation query  $id=$_get['id'];   # selects title , description fields database  $sql = "select a_answer $tbl_name question_id='$id'";  $result=mysql_query($sql); $rows=mysql_fetch_array($result);  ?>  <h3>edit</h3> <form action="save_edit.php" enctype="multipart/form-data" method="post" name="myform" />    <table>       <tr>        <td><b>answer</b></td>        <td><textarea cols="80%" rows="10" name="a_answer"><?php echo $rows['a_answer']; ?></textarea></td>      </tr>      </table>   <input name="id" type="hidden" value="<? echo $id; ?>">       <input name="enter" type="submit" value="edit"> </form>      <?php mysql_close(); ?>

another way go things use prepared statements, , let php , mysql quess correct type. here can found simple example.
