Javascript 如何将变量传递到另一个页面

index.php

$typesql = $_GET['type']

fetch_pages.php

$results = $mysqli->prepare("SELECT name, type FROM artists WHERE type = ?);

$results->bind_param("s", $typesql);
$results->execute();
$results->bind_result($name, $type);

session_start(); 
$typesql = $_GET["type"];
$_SESSION["typesql"] = $typesql; 

session_start();
$typesql = $_SESSION["typesql"]; 

$results = $mysqli->prepare("SELECT name, type FROM artists WHERE type = ?);

$results->bind_param("s", $typesql);
$results->execute();
$results->bind_result($name, $type);

我使用上面的方法在index.php中获取艺术家类型，我想将其传递到fetch.php中使用，并将其绑定到我的sql查询。

您可以将$\u get值放入会话，并且可以使用该会话变量访问另一页上的数据

示例
第1页

session_start();
$_SESSION['type']=$_GET['type'];

第2页

session_start();
$type = $_SESSION['type'];

---

您可以通过url查询传递任何参数（但url的长度是有限的）

在

index.php中

<a href="/fetch_pages.php?type=<?=$typesql?>">fetch pages</a>

// get type from url
$typesql = $_GET['type'];
// and then bind it to sql.

数据可以通过各种方式传递到下一页。您可以通过以下方式将变量传递到下一页

Url变量

但在您的情况下，使用会话是正确的方法

index.php

$results = $mysqli->prepare("SELECT name, type FROM artists WHERE type = ?);

$results->bind_param("s", $typesql);
$results->execute();
$results->bind_result($name, $type);

session_start(); 
$typesql = $_GET["type"];
$_SESSION["typesql"] = $typesql; 

session_start();
$typesql = $_SESSION["typesql"]; 

$results = $mysqli->prepare("SELECT name, type FROM artists WHERE type = ?);

$results->bind_param("s", $typesql);
$results->execute();
$results->bind_result($name, $type);

fetch_pages.php

$results = $mysqli->prepare("SELECT name, type FROM artists WHERE type = ?);

$results->bind_param("s", $typesql);
$results->execute();
$results->bind_result($name, $type);

session_start(); 
$typesql = $_GET["type"];
$_SESSION["typesql"] = $typesql; 

session_start();
$typesql = $_SESSION["typesql"]; 

$results = $mysqli->prepare("SELECT name, type FROM artists WHERE type = ?);

$results->bind_param("s", $typesql);
$results->execute();
$results->bind_result($name, $type);

使用查询字符串将值从一个页面传递到另一个页面。比如localhost/fetch.php？类型=
