PHP-动态更改变量
[英]PHP - Dynamically change variable
问题描述
My website runs on a single page with dynamic CSS changes. 
我的网站在具有动态CSS更改的单个页面上运行。 If I want to direct the client to a page content, all I do is giving the page link with passing CSS id. 如果我想将客户端定向到页面内容，我要做的就是给页面链接传递CSS ID。 ie: www.ilstours.net/index.php?css=1 即： www.ilstours.net/index.php？css = 1
index.php: index.php：
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="css/<?php echo $css; ?>.php" />
</head>
<body>
<button id="button1" type="button" onclick="index.php?css=2">Update</button> 'HERE
</body>
</html>
1.php: 1.php：
<?php
header("Content-type: text/css; charset: UTF-8");
$Color = "black";
?>
body {background-color:<?php echo $Color ?>;}
2.php: 2.php：
<?php
header("Content-type: text/css; charset: UTF-8");
$Color = "red";
?>
body {background-color:<?php echo $Color ?>;}
How can I switch to CSS file 2.php upon button click? 单击按钮后如何切换到CSS文件2.php？

当您通过url传递值时，请使用$ _GET访问它
<link rel="stylesheet" type="text/css" href="css/<?php echo $_GET['css']; ?>.php" />

index.php index.php
<?php
$css = 1; // default css (1)
if(isset($_REQUEST['css']) && ($_REQUEST['css']==1 || $_REQUEST['css']==2))
{
$css = $_REQUEST['css']; // update by click on button (1 or 2)
}
?>
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="css/<?php echo $css; ?>.php" />
</head>
<body>
<button id="button1" type="button" onclick="location.href='index.php?css=1';">Update CSS 1</button>
<button id="button1" type="button" onclick="location.href='index.php?css=2';">Update CSS 2</button>

if(isset($_GET['css'])) {
echo '<link rel="stylesheet" type="text/css" href="css/'.$_GET['css'].'.php" />';
}

Better keep your css in single array like 最好将CSS保持在单个数组中
<?php
$my_css = array("1"=>"1.css","2"=>"2.css",'deflt' => 'defualt.css');
?>
and include css like 并包括像
<link rel="stylesheet" type="text/css" href="css/<?php echo (isset($_GET['css']) && isset($my_css[$_GET['css']])) ? $my_css[$_GET['css']] : 'defualt.css'; ?>" />
