[英]Store data on my XML file while redirecting it to my home page using PHP and Javascript
I have created a PHP page where there is a form which would store data on an XML file. 我创建了一个PHP页面,该页面中有一种表单会将数据存储在XML文件中。
I have written the code of PHP which could store the data but now I have to redirect it to my homepage also. 我已经写了可以存储数据的PHP代码,但是现在我也必须将其重定向到我的主页。 But the main error is when I write the Javascript code for redirecting the page, then the data is not stored. 但是主要的错误是当我编写用于重定向页面的Javascript代码时,则没有存储数据。
Now I have currently written the code of Javascript in the PHP code itself. 现在,我目前已经在PHP代码本身中编写了Javascript代码。
I will provide the code for my page below. 我将在下面为我的页面提供代码。
<html>
<head>
<title>Login</title>
</head>
<body bgcolor="#f0f0f0">
<?php
if(isset($_REQUEST['ok']))
{
$xml = new DOMDocument("1.0","UTF-8");
$xml->load("a.xml");
$rootTag = $xml->getElementsByTagName("document")->item(0);
$dataTag = $xml->createElement("data");
$aTag=$xml->createElement("a",$_REQUEST['a']);
$bTag=$xml->createElement("b",$_REQUEST['b']);
$dataTag->appendChild($aTag);
$dataTag->appendChild($bTag);
$rootTag->appendChild($dataTag);
$xml->save("a.xml");
}
echo "<script type=\"text/javascript\">
function Home()
{
window.location.href=\"navbar.php\";
}
</script>
"
?>
<form action="index.php" method="post">
<table cellspacing="20px" style="margin-left:500px;" id="atable">
<tr>
<td>User Name </td>
<td> <input type="text" name="a" width="75" /> </td> <!--Inserting textbox in the page with justified width-->
</tr>
<tr>
<td> Password </td>
<td> <input type="password" name="b" width="75" /> </td> <!--Inserting textbox in the page with justified width-->
</tr>
<tr>
<td>
<input type="button" name="ok" value="Login" onclick="Home()" />
</td>
</tr>

</form>
</body>
</html>
Try this. 尝试这个。 You need to use header("Location:navbar.php");
您需要使用header("Location:navbar.php");
<?php
if(isset($_REQUEST['ok'])){
$xml = new DOMDocument("1.0","UTF-8");
$xml->load("a.xml");
$rootTag = $xml->getElementsByTagName("document")->item(0);
$dataTag = $xml->createElement("data");
$aTag=$xml->createElement("a",$_REQUEST['a']);
$bTag=$xml->createElement("b",$_REQUEST['b']);
$dataTag->appendChild($aTag);
