我试图发布数据并将其放入 msql 数据库，但是当我执行 print_r($_POST);它显示数组为空。我知道它正确地获取了值但是它没有发布

下面是获取帖子的 php 页面，但它显示 array() 为空白。也没有任何错误报告。
<?php
error_log(E_ALL);
if( isset($_POST) ) echo "NO POST<BR>";
print_r($_POST);
include("connection.php");
$stmt = $db->stmt_init();
if($stmt->prepare("INSERT INTO users (BusinessName, Password, Phone, Email ) VALUES (?, ?, ?, ?)")) {
$stmt->execute();
$stmt->close();
}
?>
$(function()
{
alert($("#signupUsername").val());
$("#signupSubmit").click(function() {
alert("posting "+$("#signupUsername").val());
$.post( "../signup.php",
{ username: $("#signupUsername").val(),
password: $("#signupPassword").val(),
phonenumber: $("#signupphoneNumber").val(),
email: $("#signupEmail").val()
})
.done( function(r)
{
alert("done");
})
.fail( funciton()
{
alert("fail");
});
});
alert("loaded");
});
最佳答案
你的 <input>标签需要 name属性。它将被用作您的 $_POST 中的索引，所以，这个输入:
<input name="some" type="text"/>
将产生:
$_POST['some']
