Dav*_*vid 1 php mysql post redirect insert
我有一个页面,其中谁发布了同一页面的帖子.我希望在成功的数据库INSERT之后使用新数据刷新该页面.
让我添加一些代码.
如default.php
<?php
session_start();
require("dbconfig.php");
include("head.php");
//if user is not signed in, redirect to login page
if (!isset($_SESSION['sess_user']) ) {
header ("Location: login.php");
exit;
}
?>
<body>
<div id="menu">
<?php
include("menu.php"); //include the menu
?>
</div>
<div id="page_content">
<?php
include ($p); //Include selection from menu.php
?>
</div>
?>
dbconfig.php
<?php
DEFINE ('DB_USER', 'someuser');
DEFINE ('DB_PASSWORD', 'somepassword');
DEFINE ('DB_HOST', 'localhost');
DEFINE ('DB_NAME', 'somedatabase');
$connection = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD) or
die('Connection to the specified database couldn\'t be established');
mysql_select_db(DB_NAME) or
die ('Specified database couldn\'t be selected');
function db_escape ($post)
{
if (is_string($post) ) {
if (get_magic_quotes_gpc() ) {
$post = stripslashes($post);
}
return mysql_real_escape_string ($post);
}
foreach ($post as $key => $val) {
$post [$key] = db_escape($val);
}
return $post;
}
?>
页/ cities.php
<?php
//if not signed in correctly, redirect to login page
session_start();
if (!isset($_SESSION['sess_user']) ) {
header ("Location: login.php");
exit;
}
?>
<h2>Available cities</h2>
<?php
//List all available cities from database
$cities_query = "SELECT city_name FROM city_selection";
$cities_result = mysql_query($cities_query);
while ($row = mysql_fetch_assoc($cities_result)) {
echo $row['city_name'] . "<br />";
}
?>
<?php
//Add new city to list
if(isset($_POST['submit'])){
$city_name = $_POST['city_name'];
$query="INSERT into city_selection (city_name) values ('$city_name')";
$result = mysql_query($query);
}
?>
<hr>
<h2>Add new city</h2>
<form method="post" action="default.php?p=settings_cities">
Namn: <input type="text" name="city_name">
<input type="submit" name="submit" value="Add city">
</form>
这段代码可能不太漂亮,但可行.它成功地为数据库添加了一条新记录,但我希望在帖子后用我的ny记录刷新page/cities.php.这可能吗？
让我补充一点,这是我的第一个php页面.我只读了一些书,所以不要打扰我为一个糟糕的程序员:)
是的,只需将插入部件移动到选择部件上方即可.

$city_name = $_POST['city_name'];
$query="INSERT into city_selection (city_name) values ('$city_name')";
$result = mysql_query($query);
}
?>
