如何将以HTML格式输入的字符串保存为文本文件 [英] How to save string entered in HTML form to text file
问题描述
我有一个非常基本的PHP文件。我想有两个用于用户输入的文本框和一个提交按钮。用户将输入他们的名字和姓氏，然后我想添加或创建一个TXT文件，输入从field1和field2输入的数据。
可能我正在进行这是错误的方式。
< html>我将会发布两种我一直在琢磨的方式。
< head>
< title> Field1& 2'; /标题>
< / head>
< body>
< form>
你叫什么名字？< br>
< input type =textname =field1>< br>
< input type =textname =field2>< br>
< input type =submitvalue =提交>
< / form>
<？php
$ txt = $ _POST ['field1']。' - '。$ _ POST ['field2'];
$ var_str3 = var_export（$ txt，true）; //是否有必要？
$ var3 =$ var_str3; //是否有必要？
file_put_contents（'fields.txt'，$ var3.PHP_EOL，FILE_APPEND）;
？>
< / body>
< / html>
我无法弄清楚如何将field1和field2中的数据转换为字符串变量。
我也使用这个php而不是上面列出的部分
<？php
$ txt =data.txt;
if（isset（$ _ POST ['field1']）& isset（$ _ POST ['field2']））{
$ fh = fopen（$ txt，'a'）;
$ txt = $ _ POST ['field1']。' - '。$ _ POST ['field2'];
fwrite（$ fh，$ txt）; //将信息写入文件
fclose（$ fh）; //关闭文件
}

在您的代码中，您必须使用表单HTTP方法。并且表单数据必须发送到PHP文件进行处理。
在这段代码中，我使用HTTP PSOT方法，您也可以使用GET方法，结果将相同。这两种方法用于收集表单数据。而php文件名是action.php。
index.html
< html>
< head>
< title>字段1& 2'; /标题>
< / head>
< body>
< form action =action.phpmethod =post>
你叫什么名字？< br>
< input type =textname =field1>< br>
< input type =textname =field2>< br>
< input type =submitvalue =提交>
< / form>
< / body>
< / html>
action.php
<？php
$ path ='data.txt';
if（isset（$ _ POST ['field1']）& isset（$ _ POST ['field2']））{
$ fh = fopen（$ path，a +）;
$ string = $ _POST ['field1']。' - '。$ _ POST ['field2'];
fwrite（$ fh，$ string）; //将信息写入文件
fclose（$ fh）; //关闭文件
}

I have a very basic PHP file. i want to have two textboxes for user input, and a submit button. The user will enter their first and last name, then i would like to append or create a TXT file with the data entered from field1 and field2.
Possibly i am going about this the wrong way. I will post two of the ways i have been tinkering around with.
<html>
<head>
<title>Field1 & 2</title>
</head>
<body>
<form>
What is your name?<br>
<input type="text" name="field1"><br>
<input type="text" name="field2"><br>
<input type="submit" value="Submit">
</form>
<?php
$txt= $_POST['field1'].' - '.$_POST['field2'];
$var_str3 = var_export($txt, true); //is this necessary?
$var3 = "$var_str3"; //is this necessary?
file_put_contents('fields.txt', $var3.PHP_EOL, FILE_APPEND);
?>
</body>
</html>
I cant figure out how to get the data from field1 and field2 into a string variable.
I have also messed around with using this php instead of the section listed above
<?php
$txt= "data.txt";
if (isset($_POST['field1']) && isset($_POST['field2'])) {
$fh = fopen($txt, 'a');
$txt=$_POST['field1'].' - '.$_POST['field2'];
fwrite($fh,$txt); // Write information to the file
fclose($fh); // Close the file
}
?>
You should learn about HTML Forms And PHP Form Handling.
In your code you have to use a form HTTP method. And the form data must sent for processing to a PHP file.
In this code i use HTTP PSOT method you can also use GET method the result will be same. This two method is used for collecting the form data. And the php file name is "action.php".
index.html
<html>
<head>
<title>Field 1 & 2</title>
</head>
<body>
<form action="action.php" method="post">
What is your name?<br>
<input type="text" name="field1"><br>
<input type="text" name="field2"><br>
<input type="submit" value="Submit">
</form>
</body>
</html>
action.php
<?php
$path = 'data.txt';
if (isset($_POST['field1']) && isset($_POST['field2'])) {
$fh = fopen($path,"a+");
$string = $_POST['field1'].' - '.$_POST['field2'];
fwrite($fh,$string); // Write information to the file
fclose($fh); // Close the file
}
?>
