Save HTML Form Data in a (.txt) Text File in PHP
By Saruque Ahamed MollickHello Programmers, in this post I gonna show you a very essential task that can be easily done with Core PHP and HTML form.
Sometimes it happens that we need to store some data in local storage file rather than making it complex using the database. Yes, it’s a fact that in many cases we don’t want to store our text data in database always.
Here I am giving you an example, suppose you have an HTML form and you want to store the data submitted by the user in a text file so that you can easily access it later from that file without opening your database.
PHP Program to store HTML Form data in a .txt File
Below I have provided the PHP code to store the form data in a text file. Just took a glance at this code.
For easy understanding after the code, I have provided the explanation and how to use this code step by step.
<?php
if(isset($_POST['textdata']))
{
$data=$_POST['textdata'];
$fp = fopen('data.txt', 'a');
fwrite($fp, $data);
fclose($fp);
}
?>
Here ‘textdata’ is the name of our HTML form field that is provided below.
data.txt is a file that we have to create for storing our form submission data in it.
$data is a PHP variable to store the form field data entered by the user.
Now the HTML part`
<!DOCTYPE html>
<html>
<head>
<title>Store form data in .txt file</title>
</head>
<body>
<form method="post">
Enter Your Text Here:<br>
<input type="text" name="textdata"><br>
<input type="submit" name="submit">
</form>
</body>
</html>
Now I think you have understood the thing.

Step by step guide on How to put the HTML form field data in a text file or dot txt file in PHP
- Create a PHP file and put the below code and save it.
<!DOCTYPE html> <html> <head> <title>Store form data in .txt file</title> </head> <body> <form method="post"> Enter Your Text Here:<br> <input type="text" name="textdata"><br> <input type="submit" name="submit"> </form> </body> </html> <?php if(isset($_POST['textdata'])) { $data=$_POST['textdata']; $fp = fopen('data.txt', 'a'); fwrite($fp, $data); fclose($fp); } ?> - create a new file in the same directory or folder & name it data.txt and save it.
- Now run the PHP file.
enter any text and hit on submit button and check your data.txt file. Your text entered in the form is saved in your text file.
How to Count The Sub String from a .txt file using PHP
look at the below code. It will also work fine
<?php
$data = $_POST['textdata'];
$fp = fopen('data.txt', 'a');
fwrite($fp, $data);
fclose($fp);
this will work fine. But in some servers it might show an error like this
“Undefined index: ”
in order to prevent the error warning we use isset()
so it’s safe to use this before $_POST[‘value’];
something like this one
if(isset($_POST['value'])) {
//////your code
}
Great !!! 🙂
Thank you very much 🙂
Thanks alot!
Just two problems; 1. it prints the number 1, no idea why 2. I want each submit in new line inside the txt file
All the best!

Hi, I keep on getting this error: ERROR:crash_report_database_win.cc(428)] unexpected header
Could you please advise.
Thank you for the post!
Most probably you are getting this error because you are using old chrome which is broken. Try to uninstall chrome and reinstall it. It will fix your problem.
what are system requirement as I am running it on my laptop and data.txt file not saving any data
Kindly save the file as php and run on your server. If you are using localhost then start the server and run.
Thanks :DDDD
how to save form data/input when i click on SUBMIT button & clear from data in html.
Do I need to use localhost/xampp for this?
As you are working in PHP then you must need to use a server. You can use xampp for this if you wish.
Hi, thanks for the explanation. Why does it work perfectly in the localhost, like xampp (I mean, the data is stored in the text file), but in the remote server the data is not stored in the text file? Thank you again
How can you have more than one line. And the HTML code doesn’t do anything.
