Get user input from form, write to text file using php
提问by Joe
As part of a subscriber acquisition I am looking to grab user entered data from a html form and write it to a tab delimited text file using php.The data written needs to be separated by tabs and appended below other data.
作为订阅者获取的一部分，我希望从 html 表单中获取用户输入的数据，并使用 php 将其写入制表符分隔的文本文件。写入的数据需要由制表符分隔并附加在其他数据下方。
After clicking subscribe on the form I would like it to remove the form and display a small message like "thanks for subscribing" in the div.
单击表单上的订阅后，我希望它删除表单并在 div 中显示一条小消息，如“感谢订阅”。
This will be on a wordpress blog and contained within a popup.
这将在 wordpress 博客上并包含在弹出窗口中。
Below are the specific details. Any help is much appreciated.
下面是具体的细节。任何帮助深表感谢。
The Variables/inputs are
变量/输入是
$Fname = $_POST["Fname"];
$email = $_POST["emailPopin"];
$leader = $_POST["radiobuttonTeamLeader"];
$industry = $_POST["industry"];
$country = $_POST["country"];
$zip = $_POST["zip"];
$leader is a two option radio button with 'yes' and 'no' as the values.
$leader 是一个两个选项的单选按钮，其值为“yes”和“no”。
$country is a drop down with 40 or so countries.
$country 下降了 40 个左右的国家。
All other values are text inputs.
所有其他值都是文本输入。
I have all the basic form code done and ready except action, all I really need to know how to do is:
我已经完成了所有基本的表单代码并准备好了，除了行动，我真正需要知道如何做的是：

// the name of the file you're writing to
$myFile = "data.txt";
// opens the file for appending (file must already exist)
$fh = fopen($myFile, 'a');
// Makes a CSV list of your post data
$comma_delmited_list = implode(",", $_POST) . "\n";
// Write to the file
fwrite($fh, $comma_delmited_list);
// You're done
fclose($fh);
replace the , in the impode with \t for tabs
用 \t 替换 , 在 impode 中用于制表符

Open file in append mode
以追加模式打开文件
$fp = fopen('./myfile.dat', "a+");
And put all your data there, tab separated. Use new line at the end.
并将所有数据放在那里，制表符分隔。最后使用新行。
fwrite($fp, $variable1."\t".$variable2."\t".$variable3."\r\n");
Close your file
关闭您的文件
fclose($fp);

// format the data
$data = $Fname . "\t" . $email . "\t" . $leader ."\t" . $industry . "\t" . $country . "\t" . $zip;
// write the data to the file
file_put_contents('/path/to/your/file.txt', $data, FILE_APPEND);
// send the user to the new page
header("Location: http://path/to/your/thankyou/page.html");
exit();
By using the header() function to redirect the browser you avoid problems with the user reloading the page and resubmitting their data.
通过使用 header() 函数重定向浏览器，您可以避免用户重新加载页面和重新提交数据的问题。

To swap out the form is relatively easy. Make sure you set the action of the form to the same page. Just wrap the form inside a "if (!isset($_POST['Fname']))" condition. Put whatever content you want to show after the form has been posted inside the "else{}" part. So, if the form is posted, the content in the "else" clause will be shown; if the form isn't posted, the content of the "if (!isset($_POST['Fname']))", which is the form itself will be shown. You don't need another file to make it work.
To write the POSTed values in a text file, just follow any of the methods other people have mentioned above.
换出表格相对容易。确保将表单的操作设置为同一页面。只需将表单包装在“if (!isset($_POST['Fname']))”条件中即可。将您想在表单发布后显示的任何内容放入“else{}”部分。所以，如果表单被张贴，“else”子句中的内容将被显示；如果表单未发布，则将显示“if (!isset($_POST['Fname']))”的内容，即表单本身。您不需要其他文件即可使其工作。
要将 POSTed 值写入文本文件，只需按照其他人在上面提到的任何方法即可。

This is the best example with fwrite() you can use only 3 parameters at most but by appending a "." you can use as much variables as you want.
这是 fwrite() 的最佳示例，您最多只能使用 3 个参数，但可以附加一个“.”。您可以根据需要使用尽可能多的变量。
if isset($_POST['submit']){
$Fname = $_POST["Fname"];
$email = $_POST["emailPopin"];
$leader = $_POST["radiobuttonTeamLeader"];
$industry = $_POST["industry"];
$country = $_POST["country"];
$zip = $_POST["zip"];
$openFile = fopen("myfile.ext",'a');
$data = "\t"."{$Fname}";
$data .= "\t"."{$email}";
$data .= "\t"."{$leader}";
$data .= "\t"."{$industry}";
$data .= "\t"."{$country}";
$data .= "\t"."{$zip}";
fwrite($openFile,$data);
fclose($openFile);
}

Very very simple:Form data will be collected and stored in $var data in $var will be written to filename.txt \n will add a new line. File Append Disallows to overwrite the file
非常非常简单：表单数据将被收集并存储在 $var 中， $var 中的数据将被写入 filename.txt \n 将添加一个新行。File Append 不允许覆盖文件
<?php
$var = $_POST['fieldname'];
file_put_contents("filename.txt", $var . "\n", FILE_APPEND);
exit();
?>
