Question

我的代码在MySQL表“table1”中插入一条空记录，而不是在form1.html中的“Name”字段中插入。知道为什么它插入空记录而不是用户在字段中输入的内容吗？

form1.html

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
    "http://www.w3.org/TR/html4/strict.dtd"
    >
<html lang="en">
<head>
    <title>Insert Your Name</title>
</head>
<body>
    <h3> Insert Your Name</h3>
    <form action="form1.php" method="post">
        <input type="text" name="Name">
            <input type="Submit" value="Submit" name="Submit">
    </form>
</body>
</html>

form.php的

> <?php 
> $connection =
> mysql_connect("localhost","root","")
> or die ("Couldn't Connect To Server");
> $db = mysql_select_db("db1",
> $connection) or die ("Couldn't Select
> Database"); $query = "CREATE TABLE IF
> NOT EXISTS table1 (Name VARCHAR(20))";
> $result = mysql_query($query) or die
> ("Query Failed: " . mysql_error());
> $query = "INSERT INTO table1 (Name)
> VALUES ('$_post[Name]')"; $result =
> mysql_query($query) or die ("Query
> Failed: " . mysql_error()); $query =
> "SELECT * FROM table1"; $result =
> mysql_query($query) or die ("Query
> Failed: " . mysql_error());
>     echo "<TABLE BORDER = '1'>";
>     echo "<TR>";
>     echo "<TH>Name</TH>";
>     echo "</TR>";
>     
>     while ($row = mysql_fetch_array($result))
>     {
>         echo "<TR>";
>         echo "<TD>", $row['name'], "</TD>";
>         echo "</TR>";
>     }
>     echo "</TABLE>";
>     mysql_close($connection); ?>

Answer 1

而不是

$query = "INSERT INTO table1 (Name) VALUES ('$_post[Name]')";

试试这个

$query = "INSERT INTO table1 (Name) VALUES ('" .
          mysql_real_escape_string($_post['Name'],$db) . "')";

Answer 2

请更改此

<input type="text" name="fname">


$query = "INSERT INTO table1 (Name)
 VALUES ('".mysql_real_escape_string($_POST[fname],$db)."')";

Answer 3

 $query = "INSERT INTO table1 (Name)
 VALUES ('{$_POST[Name]}')"; $result =
 mysql_query($query) or die ("Query
 Failed: " . mysql_error());

$_POST和$_GET是大写的。

将显示代码更改为：

 while ($row = mysql_fetch_array($result))
     {
         echo "<TR>";
         echo "<TD>", $row['Name'], "</TD>";
         echo "</TR>";
     }

Answer 4

 " . ($_POST['Fname'] != "") ? $_POST['Fname'] : "No Name" ."

PHP代码将空记录插入MySQL DB
