我是PHP的新手,我只是在做一个简单的输入表单网页。问题是,在提交网站进入空白页面后,我希望它回到原来的那个。我在这里读到,可以通过向我的代码添加header()来帮助它,但它没有帮助。这是我的代码:
<!DOCTYPE html>
<html>
<head>
<title> Sample Form </title>
<link href = "stl.css" rel = "stylesheet" type="text/css" />
</head>
<body>
<form method="post" action="connect.php">
<input class = "PaganForm" id = "name" type="text" name="name" value="">
<input class = "PaganForm" id = "img" type="text" name="img" value="">
<input class = "PaganForm" id = "dsc" type="text" name="dsc" value="">
<input type="submit" id = "SubmitButton" >
</form>
<?php
header("Location: http://localhost/simple-form.php");
exit;
$servername = 'localhost';
$username = 'root';
$password = '';
$database = 'cero_db';
$conn = new mysqli($servername, $username, $password,$database);
$sql = "SELECT * FROM pg";
$result = $conn->query($sql);
while($row = $result->fetch_assoc()) {
$newName = $row['Name'];
$newLink = $row['Link'];
$newDsc = $row['Description'];
echo "<h1>".$newName."</h1>";
echo "<img src = \"".$newLink."\" />";
echo "<p>".$newDsc."</p>";
}
?>
<body>
</html>
这是connect.php:
<?php
$name = $_POST["name"];
$lnk = $_POST["img"];
$dsc = $_POST["dsc"];
$servername = 'localhost';
$username = 'root';
$password = '';
$database = 'cero_db';
$conn = new mysqli($servername, $username, $password,$database);
$sql = "INSERT INTO pg (Name, Link, Description)
VALUES ('".$name."', '".$lnk."', '".$dsc."')";
$conn->query($sql);
?>
有什么建议吗?
P.S。我找不到任何帮助我的问题,所以如果重复只是链接原文,我会删除它。

试试这个
header("Location: simple-form.php");
您必须在connect.php
中添加此内容,因为表单中的提交按钮会引导您connect.php
。
你的connect.php应如下所示:3
<?php
$name = $_POST["name"];
$lnk = $_POST["img"];
$dsc = $_POST["dsc"];
$servername = 'localhost';
$username = 'root';
$password = '';
$database = 'cero_db';
$conn = new mysqli($servername, $username, $password,$database);
$sql = "INSERT INTO pg (Name, Link, Description)
VALUES ('".$name."', '".$lnk."', '".$dsc."')";
$conn->query($sql);
header("Location: simple-form.php");
?>

我会在它被评论堵塞之前写在这里:
您需要将标题函数移动到将发送到浏览器的任何内容之上。由于您在调用标头之前发送了一些html,因此标头已经与您的html代码一起发送。 了解它http://php.net/manual/en/function.header.php 它在SO上被广泛询问以及搜索php头重定向
因此,您需要处理您发送任何输出或使用输出缓冲的表单。我建议您查看http://php.net/manual/en/function.ob-start.php
您还可以使用javascript将用户发送到正确的位置。
