问题描述
我试图填充一个html表单，数据从我的mysql数据库中接收。但是，我无法设置窗体显示正在加载从数据库中提取的变量。我希望载入的表单将最后输入的数据保存到之前添加到数据库中的表格中。
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();
?>

推荐答案
你的mysql查询中有语法错误。您没有放置字段或列名称或（ * ）提取所有列。
You have syntax error in your mysql query. You have not place field or columns name or (*) for all columns to extract.
请尝试这样。 。
$query = "SELECT * FROM character_tbl WHERE character_player ='".$_SESSION['user']."'";
