我是php世界的新手,我试图通过一个简单的页面来学习它。 我已经创建了一个html表单,我想使用ajax发送数据,但它仍然存在 POST http://localhost/Home.php 500(内部服务器错误)
特别是我想为我正在用于测试的数据库中的每个表创建一个按钮,当我按下一个按钮时,它将显示数据库中的所有行(我还没有实现它,我是只是试图强调php和ajax如何沟通)
这是我的表格(Home.php)
<?php
session_start();
if(!isset($_SESSION['login'])) {
header("Location: Login.php");
unset($_REQUEST);
}
else echo "<span class=\"welcome\"><strong>Benvenuto</strong> <em>" . $_SESSION['username'] . "</em></span>";
?>
<html>
<head>
<link rel="stylesheet" type="text/css" href="style.css">
<script src='jquery-1.11.3.js'></script>
<script src='Script.js'></script>
</head>
<body>
<div id="functions">
<button id="createTable">CREATE</button>
<button id="displayTable">DISPLAY</button>
</div>
<div id="createForm">
<form id="queryForm" method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>">
<input class ="text" name="query" type="text" size="50">
<input type="submit" class="submit" name="createQuery">
</form>
</div>
<div id="displayForm">
<form method="post" id="selectForm">
<?php
include ("Database.php");
$Database = new Database( "localhost", "root", "1234");
$Database->connectToServer();
$Database->connectToDatabase("test");
$Tables = $Database->countTable();
foreach($Tables as $column) {
echo "<input type=\"radio\" class=\"submit\" id=\"selectQuery\" name=\"selectQuery\" value=\"". $column . "\"> " . $column;
}
?>
<input type="submit" class="submit" name="createSelect">
</div>
<div style="position:absolute; bottom:10px; left:50%; font-size: 15pt"></span><em>...</em> <a href="Logout.php">Logout</a></div>
</body>
</html>
<?php
if(isset($_POST['createQuery'])) {
include ("Database.php");
$Database = new Database( "localhost", "root", "1234");
$Database->connectToServer();
$Database->connectToDatabase("test");
$Database->createTable($_POST["query"]);
header("Location:Home.php");
}
?>
这是我的ajax文件
$(document).ready(
function() {
$("#createTable").click(goCreate);
$("#displayTable").click(goDisplay);
$('#selectForm').submit(goSelect);
$("#createForm").hide();
$("#displayForm").hide();
}
);
function goCreate(data) {
$("#createForm").show();
$("#functions").hide();
}
function goDisplay(data) {
$("#displayForm").show();
$("#functions").hide();
}
function goSelect() {
var selectedTable = $("#selectQuery:checked").val();
console.log($("#selectQuery:checked").val());
$.ajax({
url: "Prova.php",
type: "POST",
dataType: "html",
data: {
'select': 'display',
'table': selectedTable
},
success: function(msg) {
console.log(msg);
},
error: function(xhr, desc, err) {
console.log("error");
console.log(xhr);
console.log("Details: " + desc + "\nError:" + err);
}
}); // end ajax call
return false;
};
这是我管理ajax电话的Prova.php
<?php
include 'ChromePhp.php';
ChromePhp::log("corretto");
echo "ok belo";
?>
答案 0 :(得分:0)
您可以打开错误日志,如下所示:
error_reporting(1);
ini_set('display_errors', 1);
你能分享整个home.php文件代码,因为这可能有助于其他人帮助你:) 也找不到用于处理“createSelect”按钮的事件监听器。我错过了什么吗?
