【问题描述】:
我的 html 页面有一些问题。我希望它在按下提交按钮后重新加载。我尝试使用 javascript 重新加载它,但它一直给我一个白页(在将我需要的数据保存在文件中之后)。
这里是html代码:
<html>
<head>
<title>Sample Web Form</title>
</head>
<body>
<h1>Fill Out This Form</h1>
<form action="myprocessingscript.php" method="POST">
<p><i>Choose one or more of the available options that represent the current mental state of the System:</i></p>
<input type="checkbox" name="mentalState[]" value="Knows user culture"> Knows User Culture<br>
<input type="checkbox" name="mentalState[]" value="Knows concept "> Knows Concept<br>
<input type="checkbox" name="mentalState[]" value="Knows that user knows concept"> Knows that User Knows Concept<br>
<p><i>Choose the corresponding action:</i></p>
<input type="checkbox" name="action" value="cultureIdentif"> Culture Identification<br>
<input type="checkbox" name="action" value="conceptIdentif"> Concept Identification<br>
<p><i>Choose one or more of the available options that represent the current mental state of the System following the action:</i></p>
<input type="checkbox" name="mentalState2[]" value="Knows user culture"> Knows User Culture<br>
<input type="checkbox" name="mentalState2[]" value="Knows concept"> Knows Concept<br>
<input type="checkbox" name="mentalState2[]" value="Knows that user knows concept"> Knows that User Knows Concept<br>
</br>
<input type="submit" value="Save Data">
</form>
</body>
</html>
这里是php代码:
<?php
if(!empty($_POST['mentalState'])){
// Loop to store and display values of individual checked checkbox.
foreach($_POST['mentalState'] as $mentalState)
($mentalState1=$mentalState . ',' . $mentalState1);
}
if(!empty($_POST['mentalState2'])){
// Loop to store and display values of individual checked checkbox.
foreach($_POST['mentalState2'] as $mentalState)
($mentalState2=$mentalState . ',' . $mentalState2);
}
if(isset($mentalState1) && isset($_POST['action']) && isset($mentalState2)) {
$data = $mentalState1 . '-' . $_POST['action'] . '-' . $mentalState2 . "\n";
$ret = file_put_contents('matrix.txt', $data, FILE_APPEND | LOCK_EX);
if($ret === false) {
die('There was an error writing this file');
}
} else {
die('no post data to process');
}
感谢您的帮助!

将
header( "Location: $_SERVER['HTTP_REFERER']" ) ;放在最后一个IF语句中,当它正确完成时,它会将您重定向回您提交的页面。 -
你能写文件吗?
-
一些合理的代码缩进是个好主意。它可以帮助我们阅读代码,更重要的是,它将帮助您调试代码 Take a quick look at a coding standard 为您自己谋福利。

HTML 和 PHP 是否在 2 个单独的文件中?
-
谢谢,我将编辑代码格式。是的。
