学完了记得动手操作。
測试地址（未过滤）
<html> <body> <head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /></head> <form method = "post" action = "post.php"> 欢迎来到我的留言板！<br> name:<input type = "text" name = "name"><br> email:<input type = "text" name = "email"><br> content:<br> <textarea rows="10" cols="20" name="content"> </textarea> <input type = "submit"> </form> </body> </html>
<?php
header("Content-type: text/html; charset=utf-8");
$con = mysql_connect("***","***","***");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
//connect table
mysql_query("SET NAMES utf8");
mysql_select_db("message",$con);
$sql = "CREATE TABLE message(
id int NOT NULL AUTO_INCREMENT,
PRIMARY KEY(id),
name varchar(15),
email varchar(15),
content varchar(100)
)";
//mysql_query($sql,$con);
$name = $_POST['name'] ;
$email = $_POST['email'];
$content = $_POST['content'];
$sql1 = "INSERT INTO message(name,email,content)
VALUES( '$name', '$email','$content')";
mysql_query($sql1,$con);
echo "<table border='1'>
<tr>
<th>id</th>
<th>name</th>
<th>email</th>
<th>content</th>
</tr>";
$result = mysql_query("SELECT * FROM message");
while($row = mysql_fetch_array($result))
{
echo "<tr>";
echo "<td>" . $row['id'] . "</td>";
echo "<td>" . $row['name'] . "</td>";
echo "<td>" . $row['email'] . "</td>";
echo "<td>" . $row['content'] . "</td>";
echo "</tr>";
}
echo "</table>";
mysql_close($con);
?>mysql_fetch_array(): supplied argument is not a valid MySQL result resource
定位到该函数。$result的值不是有效的。
怀疑是数据库没有连接成功。
推断一下$result。输出mysql_error();
发现是没有数据库选择。
原来放在本地能够运行的，原来放到站点上数据库名称写成表单名称了。
蠢哭。
