HTML按钮提交不激活php代码
我遇到了我的html表单没有正确提交的问题。我是新来的形式,并一直试图让登录脚本去,但它一直在失败。我大多使用铬。这是超级愚蠢的代码,希望能够证明我的问题。我猜测这段代码在扩展代码中出了什么问题。这是我用我的登录编码的网站:login account setup site mainly for referenceHTML按钮提交不激活php代码
<?php
//this is here for testing
session_start();
//this shows
echo "something";
//none of these show
if(isset($_POST['submit'])){
echo "something";
echo "something";
echo "something";
echo "something";
}
if(isset($_POST['submit2'])){
echo "something";
echo "something";
echo "something";
echo "something";
}if(isset($_POST['submit3'])){
echo "something";
echo "something";
echo "something";
echo "something";
}
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
</head>
<body>
<footer>
<!-- I have tried it with and without an action -->
<form action="button_test.php" method="post" id="this" style="width: 100%; height: 100%; background-color: darkblue;">
<button type="submit" name="submit" id="submit" class="button" value="Submit">this is something</button>
<button type="button" name="submit2" id="submit2" class="button" value="this">this is something2</button>
<input type="button" name="submit3" id="submit3" class="button" value="true"/>
</form>
</footer>
</body>
</html>
的第一个按钮可预见的重新加载页面,而其他的什么也不做。这是我需要工作的扩展主代码。再次,我猜测上面的代码可能解释了下面的代码有什么问题。下面的代码主要是为了给出上下文和更准确的答案。
<?php
//require once the DatabaseController.php file,
require_once 'Controllers/DatabaseController.php';
echo "this happend1";
// Creates a data connect object that creates a connection to
// a database
$connection = new DataConnect;
//Run the user_load function to set the user
$connection->user_load();
echo "this happend2";
/*
* Runs the in_loggedin function from a
* user object and checks if it is blank
*/
if($user->is_loggedin()!="")
{
echo "this happend3";
//return user to logged in home page if
//they are logged in
$user->redirect('index.php');
}
echo "this happend4";
/*
* THIS DOES NOT WORK FOR SOME REASON
*/
if(isset($_POST['btn-login']))
{
echo "this happend5";
//Load the variables with the new form data that has been executed
$uname = $_POST['txt_uname_email'];
$umail = $_POST['txt_uname_email'];
$upass = $_POST['txt_password'];
//If the user->login call is successful, go to home fully logged in
if($user->login($uname,$umail,$upass))
{
//Go to home, fully logged in
$user->redirect('index.php');
}
else
{
//Error
$error = "Wrong Details !";
}
}
?>

因此,经过一些搜索,我忘记透露我正在使用PHPstorm。之所以没有发生这种情况,是因为PHPstorm没有安装在我一直使用的另一台计算机上,但是由于我在两台计算机上都使用了Intellij,所以无论因为Intellij如何,PHPstorm中的这个错误都会使用PHPstorm插件。看来10.1-10.3这个bug在POST保持空白的地方依然存在。我不确定它是否被修复,所以我转移到了Apache,并且让它做了Web服务。一切正常,或至少效果更好。这两个解决方案要么等待PHPstorm来修复这个bug,要么更好地转向Apache。
由于php://input
显示形式值(根据测试我有你的意见运行),我们知道,PHP被正确接收数据。
默认情况下,PHP会根据需要在$_GET
和$_POST
中放置请求参数。在你的情况下,这似乎并没有发生。我建议你看一下你的php.ini
文件,并添加以下设置:
variables_order = "GPCS"
可能已经有一个variables_order
线,所以只是在这种情况下(documentation)编辑它。
variables_order =“GPCS”已经在我的ini中设置了 –
它没有被评论正确吗? (以';'开头)。如果是这样,请取消注释。您还需要重新启动PHP才能使更改生效。 – BeetleJuice
是的,它已经在那里。 $ _POST一直工作正常。我设置了“$ _POST ['this thing'] = 6;”在var转储之前,将其中一个if语句设置为“if(isset($ _ POST ['this thing']))”并且它可以工作。它似乎是HTML表单不设置发布。如果我移动“$ _POST ['this thing'] = 6;”到页面的末尾,然后没有任何反应。 –
让我们来测试:在脚本的顶部,你做'的var_dump($ _ POST)'和'回声的file_get_contents( 'PHP://输入')',在每行显示的内容? – BeetleJuice
我得到:array(0){} submit =提交 –
它似乎是通过按钮值,但我希望它通过按钮名称,我虽然它。我引用的网站和扩展的代码没有使用按钮中的值字段,我觉得我想保持这种方式,除非绝对需要。看来,如果声明 –
