如何根據屏幕分辨率或大小執行php文件

Question

我有2個php文件。

include_once('medium.php'); 
include_once('mobile.php'); 

我想執行medium.php文件時，屏幕尺寸> 992px和mobile.php如果屏幕尺寸是< 992px

我試了一下，到目前爲止是：

<script> 
var width = $(window).width(); 
if (width > 992){ 
</script> 
include_once('medium.php'); 
<script>} else{</script> 
include_once('mobile.php'); 
<script>}</script> 

但無法獲得結果。

Answer 1

圍棋與jQuery和Ajax $.load()功能

var width = $(window).width(); 
if (width > 992){ 
    $("body").load("medium.php"); 
} else{ 
$("body").load("mobile.php"); 
} 

Answer 2

您應該使用Ajax或Http.get屏幕寬度到PHP文件，並讓PHP處理執行

<?php 
if(isset($_GET['size']) && $_GET['size'] > 992) { 
    include_once('medium.php'); 
} else { 
    include_once('mobile.php'); 
} ?> 

Answer 3

要麼使用jQuery.load()，jQuery.post()， jQuery.get()或jQuery.ajax()

<script type="text/javascript"> 
var script = window.innerWidth > 992 ? "medium.php" : "mobile.php"; 
var postVars = {} // Use this to provide additional data to you PHP script, or ommit this parameter if you don't need it 
var dataType = 'json'; // The type of data your PHP script will return, could be html, json, text. ommit this if you don't have a particular use for it. 

jQuery.post(script, postVars, function(response) { 
    // This is your callback function, you can do whatever you please with response here. 
}, dataType) 
</script> 

安全通知 永遠不要相信最終用戶！由於這是客戶端腳本，這些變量可能會被操縱爲config.php。

爲了解決這個問題，您應該不是請求多個腳本，而是請求一個腳本，提供一個包含文件的參數，然後檢查是否允許包含該文件。

<script type="text/javascript"> 
var script = window.innerWidth > 992 ? "medium.php" : "mobile.php"; 
var postVars = {file_to_include: script} 
var dataType = 'json'; // The type of data your PHP script will return, could be html, json, text. ommit this if you don't have a particular use for it. 

jQuery.post("include.php", postVars, function(response) { 
    // This is your callback function, you can do whatever you please with response here. 
}, dataType) 
</script> 

然後在你的PHP腳本

<?php 
    if(in_array($_POST["file_to_include"], array("medium.php", "mobile.php"))) { 
     include $_POST["file_to_include"]; 
    } 
?>
