在我的网站的开头,我要求一个名字。然后,我将名称传递给具有相同$name
变量的主页。他们可以在其主页上按“内容”按钮,将其重定向到URL中带有变量$name
的内容网页。在主页上,它在$name
中显示echo "<h1>$name's Profile</h1>";
变量的值,但是由于某些原因,当我在链接上使用它时,它是不确定的。这是代码:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Profile</title>
</head>
<body>
<center>
<?php
$name = $_GET['name'];
echo "<h1>$name's Profile</h1>";
echo "<hr>";
echo "<br>";
echo "<h3>Choose an option</h3>";
if(isset($_GET['btn'])) {
$name = $_GET['name'];
$loc = 'something.php?name=' . $name;
header("Location: " . $loc);
exit();
}
?>
<input type="Submit" value="Something" name="btn">
</center>
</body>
</html>

以下应该有效
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Profile</title>
</head>
<body>
<center>
<?php
//First check if $_GET['name'] is set
if(isset($_GET['name'])){
$name = $_GET['name'];
//So here concatinate the strings and variables properly as following
echo "<h1>".$name."'s Profile</h1>".
"<hr>".
"<br>".
"<h3>Choose an option</h3>";
if(isset($_GET['btn'])) {
$name = $_GET['name'];
$loc = "something.php?name=" . $name;
header("Location: " . $loc);
die();
}else{
//There was no btn parameter in the url means $_GET['btn'] isn't set notify the user
echo "Can't Redirect The Page\nReason: Details Missing...";
}
}else{
//There was no name parameter in the url means $_GET['name'] isn't set notify the user
echo "Can't Process The Request\nReason: Details Missing...";
}
?>
<input type="Submit" value="Something" name="btn">
</center>
</body>
</html>

代码假定您有一个名为$ name的变量,而不是$ name。
关闭“并使其:
echo "<h1>" . $name . "'s Profile</h1>";
或在字符串中使用{}:
echo "<h1>{$name}'s Profile</h1>";
