我需要这方面的帮助，它应该从 nbproject/add_task_led.php?key=Marija 这样的 URL 获取 key ，并将其放入 $key 变量中，但它似乎不起作用。当我直接将名称放入此示例 Marija 而不是 $key 时，它会更改数据库。我做错了什么吗？
最佳答案
用于测试目的
您能否使用以下代码设置一个测试表，我认为这是成功的。
请务必更改这些变量以适合您自己的变量，或按如下所示创建它们:
$table_task = "table_task"; // table name
$atask = "a_task"; // column name
$db_selected = mysql_select_db('db_name', $db); // db_name is your DB
HTML/PHP/SQL(表单操作设置为 self)
<?php
if (!empty($_REQUEST['key'])) {
$key = $_REQUEST['key'];
echo "key: ". $key. "\n";
$db = mysql_connect("host","username", "password");
$db_selected = mysql_select_db('db_name', $db);
if (!$db_selected) {
die ('Can\'t use it : ' . mysql_error());
}
$table_task = "table_task";
$atask = "a_task";
$SQL = "INSERT INTO $table_task (`username`, $atask) VALUES ('$key', 'pending')";
mysql_query($SQL,$db);
// Used for my own testing purposes that you can comment out
// $SQL = "UPDATE $table_task SET a_task = 'pending_test' WHERE username = '$key'";
// mysql_query($SQL,$db);
}
?>

关于php - $key=$_REQUEST ['key' ] 不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/21465375/
