无法弄清楚如何将信息从一个 .php 文件发送到另一个 .php 文件 first.phpsecond.php

如何解决无法弄清楚如何将信息从一个 .php 文件发送到另一个 .php 文件 first.phpsecond.php

我试图通过 POST 发送一个数组，通过 GET 将 2 个变量从 first.PHP 发送到 second.PHP 文件，但我似乎无法让它工作。对于所有 3 个，我收到错误消息 Undefined index

<?PHP
    session_start();

    $_SESSION["trys"] = 0;
    echo "<hr/><pre>".print_r($_SESSION,1)."</pre><hr/>";
?>
<script>
//array
arrayIDs = [04,05,45,55]

$.ajax({
                url: 'second.PHP',type: 'post',data: {arrayIDs: arrayIDs},success: function(response){
                    console.log("POST !DELA!")
                }
            });

//string //x=0&y=9
url = "second.PHP?" + "x=" + x + "&y=" + y;
// I send it through get
</script>

<html>
//some tables data is generated from
</html>

second.PHP

<?PHP
    session_start();
    $kliknjenX =  $_GET["x"];
    $kliknjenY =  $_GET["y"];
    $kliknjenID = $kliknjenX + "" + $kliknjenY;

    $arrayIDs = $_POST['arrayIDs'];
?>

解决方法

原因是因为您实际上从未针对请求发送任何 GET 数据...

<script>
//array
arrayIDs = [04,05,45,55]

$.ajax({
                url: 'second.php',// <<-- This line doesn't have GET variables
                type: 'post',data: {arrayIDs: arrayIDs},success: function(response){
                    console.log("POST !DELA!")
                }
            });

url = "second.php?" + "x=" + x + "&y=" + y;       // <<-- This line does nothing
</script>

<html>
//some tables data is generated from
</html>

应该是：

<script>
//array
var arrayIDs = [04,55];

var x = "some_url_encoded_value";
var y = "another_encoded_value";

var destination_url = "second.php?x=" + x + "&y=" + y;    

$.ajax({
                url: destination_url,type: 'post',success: function(response){
                    console.log("POST !DELA!")
                }
            });


</script>

<html>
//some tables data is generated from
</html>

我认为这将帮助您测试它：

first.php

<?php
session_start();

$_SESSION["trys"] = 0;
echo "<hr/><pre>".print_r($_SESSION,1)."</pre><hr/>";
?>

<script>
    arrayIDs = [04,55]

    $.ajax({
        url: 'second.php?x=0&y=9',success: function(response){
            console.log("POST !DELA!")
        }
    });
</script>

<html>
//some tables data is generated from
</html>

second.php

<?php
    session_start();
    $kliknjenX =  $_GET["x"];
    $kliknjenY =  $_GET["y"];
    $kliknjenID = $kliknjenX + "" + $kliknjenY;

    $arrayIDs = $_POST['arrayIDs'];
?>
