Filling html forms with mysql data using php coming up null

问题

I am trying to fill a html form with data being received out of my mysql database. However I cannot set the forms to display on-load the variables being extracted from the database. I would like the form on-load to hold the data last entered into the forms which have been added to the database previously.

    $query = "SELECT FROM character_tbl WHERE character_player 

='".$_SESSION["user"]."' character_tbl";
    $result = mysql_query($query);
while($row = mysql_fetch_array($result)){  
$name = $row['character_name'];
$race = $row['character_race'];
$class = $row['character_class'];
$alignment = $row['character_alignment'];
$hp = $row['character_hp'];
$str = $row['character_str'];
$dex = $row['character_dex'];
$con = $row['character_con'];
$int = $row['character_int'];
$wis = $row['character_wis'];
$cha = $row['character_cha'];
$ac = $row['character_ac'];
$touch = $row['character_touch'];
$flat = $row['character_flat'];
$fort = $row['character_fort'];
$ref = $row['character_ref'];
$will = $row['character_will'];
}

echo $will;
mysql_close();

回答1:

You have syntax error in your mysql query. You have not place field or columns name or (*) for all columns to extract.

Try like this..

$query = "SELECT * FROM character_tbl WHERE character_player ='".$_SESSION['user']."'";

回答2:

I think the SQL has error:

SELECT FROM character_tbl WHERE character_player

try:

SELECT * FROM character_tbl WHERE character_player
