求助！！！大家都帮我侃侃

[w3schools]

<?
if ($UserName)
{
mysql_connect() or die ("Problem connecting to DataBase");
$query = "insert into tbl values ('$idx','$UserName','$LastName','$FreeText')";
$result = mysql_db_query("example", $query);
echo "Data inserted. new table:<br><p></p>";
$query = "SELECT * FROM tbl";
$result = mysql_db_query("example", $query);
if ($result)
...
...

怎样给'$idx','$UserName','$LastName','$FreeText'赋值（进行变量初始化）
谢谢

什么啊，能不能详细一点，谢谢了

[Cain]

$idx = $LastName = $FreeText = ""; // 初始化

$query = "insert into tbl values ('$idx','$UserName','$LastName','$FreeText')";
$result = mysql_db_query("example", $query);
echo "Data inserted. new table:<br><p></p>";

to cain:
我也遇到同样的问题，你那赋值后好象也不行，那usename那？

如果你的变量取自FORM的提交，直接名称对应控件的name即可

如果要单独赋值，同楼上！

是的，我是利用FROM提交的，你能不能详讲一下NAME怎么行？谢谢

<form method="post">
<input name=idx>
<input name=UserName>
<input name=LastName>
<input name=FreeText>
<input type=submit value="提交">
</form>

if ($UserName)
{
mysql_connect() or die ("Problem connecting to DataBase");
$query = "insert into tbl values ('$idx','$UserName','$LastName','$FreeText')";
$result = mysql_db_query("example", $query);
echo "Data inserted. new table:<br><p></p>";
$query = "SELECT * FROM tbl";
$result = mysql_db_query("example", $query);
if ($result)
