html form will not write to file (php script) – PHP Versions

I have an HTML file that contains the following form:

<form action="" class="contact-form">
<div class="input-group tm-mb-30">
<input name="username" type="text" class="form-control rounded-0 border-top-0 border-end-0 border-start-0" placeholder="Name">
</div>
<div class="input-group tm-mb-30">
<input name="email" type="text" class="form-control rounded-0 border-top-0 border-end-0 border-start-0" placeholder="Email">
</div>
<div class="input-group tm-mb-30">
<textarea rows="5" name="message" class="textarea form-control rounded-0 border-top-0 border-end-0 border-start-0" placeholder="Message"></textarea>
</div>
<div class="input-group justify-content-end">
<input type="submit" class="btn btn-primary tm-btn-pad-2" value="Save">
</div>
</form>

It seems fine to me. I also have a php script:

> <?php
extract($_REQUEST);

> $file=fopen("form.txt.", "a");
fwrite($file, "----");
fwrite($file," name :");
fwrite($file, $username ."n");
fwrite($file," email :");
fwrite($file, $email ."n");
frwite($file," message .:");
fwrite($file, $message ."n");

fclose($file);
> ?>

Both are in the same file, the form in between html tags, the php script after the /html tag.

If will not execute. No matter what I do, form.txt remains empty. form.txt is in the same directory and has 777.

Since I cannot find any problem with the script (there are no error messages in the apache log file), I am wondering if there is something wrong with the php on this server (there are also no entries in syslog). phpinfo page displays fine, and php –version tells me 8.2.1 is running.

I then changed action in form to "form.php" and added method=POST to test with separate script. form.php was simply:

<?php
        echo "NAME:";
        echo $username;
        echo "EMAIL:";
        echo $email;
        echo "MESSAGE:";
        echo $message;

        echo "POSTNAME:";
        echo $_POST['username'];
        echo "POSTEMAIL:";
        echo $_POST['email'];
        echo "POSTMESSAGE:";
        echo $_POST['message'];
?>

I did not get any output for the first three entries. But I got output for the last three entries. I expected to get output for all – since the form, by sending the inputs, should automatically create/define those variables. Am I wrong?

I then added this to form.php (in front of the code mentioned above) in order to define the variables:

 if(isset($_POST['submit']))
 {
        //fetch form data
        $username = $_POST['username'];
        $email = $_POST['email'];
        $message = $_POST['message'];
 }

because I thought defining them would solve the problem. It did not. When executing form.php (by sending the form in the html), apache.log now tells me that $username, $email and $message are not defined. But I just defined them…. ärx

    So this solved it for me:

    I added "name=submit" to the submit input in HTML. The form posts to form.php, which now looks like this:

    <html>
<body>
 
<?php
 
// turn on error reporting
ini_set('error_reporting', 'on');
error_reporting(E_ALL);
 
// Remove all illegal characters from email
// $email_address = filter_var($email_address, FILTER_SANITIZE_EMAIL);
 
// check if form has been submitted
if(isset($_POST['submit']))
{
//fetch form data
$username = $_POST['username'];
$email = $_POST['email'];
$message = $_POST['message'];
 
//write form data
$fp = fopen('form.txt', 'a');
fwrite($fp, "---");
fwrite($fp,"name :");
fwrite($fp, $username ."n");
fwrite($fp," email :");
fwrite($fp, $email ."n");
fwrite($fp," message :");
fwrite($fp, $message ."n");
fclose ($fp);
}
 
//show submitted data
echo "NAME:";
echo $username;
echo "<br>";
 
echo "EMAIL:";
echo $email;
echo "<br>";
 
echo "MESSAGE:";
echo $message;
echo "<br>";
 
echo "POSTNAME:";
echo $_POST['username'];
echo "<br>";
 
echo "POSTEMAIL:";
echo $_POST['email'];
echo "<br>";
 
echo "POSTMESSAGE:";
echo $_POST['message'];
echo "<br>";
 
 
// extract($_REQUEST); might need to be added
?>
The data has been submitted - thanks
</body>
</html>

    For some reason, the extract command seems unnecessary; it works fine without it, but I am not sure why. Anyhow, the data is now processed into the file. I got it. Thanks so much, everyone!

    Remove the last dot (.) from filename form.txt.

    WRONG FILE NAME form.txt.

    $file=fopen("form.txt.", "a");

    CORRECT FILE NAME

    $file=fopen("form.txt", "a");

    Now all entries will go to form.txt file.

    Full Code is shared here:

    1. Add form method as POST and add name=’submit’ to submit button

       <form action="" class="contact-form" method="post">
 <div class="input-group tm-mb-30">
     <input name="username" type="text" class="form-control rounded-0 border-top-0 border-end-0 border-start-0" placeholder="Name">
 </div>

 <div class="input-group tm-mb-30">
     <input name="email" type="text" class="form-control rounded-0 border-top-0 border-end-0 border-start-0" placeholder="Email">
 </div>
 <div class="input-group tm-mb-30">
     <textarea rows="5" name="message" class="textarea form-control rounded-0 border-top-0 border-end-0 border-start-0" placeholder="Message"></textarea>
 </div>
 <div class="input-group justify-content-end">
     <input type="submit" class="btn btn-primary tm-btn-pad-2" value="Save" name="submit">
 </div>
 </form>

    2. If form is submitted then write to file. Also you have typo mistake in frwite which is corrected too here.

       if(isset($_POST['submit'])){

 extract($_REQUEST);

 $file=fopen("form.txt", "a");
 fwrite($file, "----");
 fwrite($file," name :");
 fwrite($file, $username ."n");
 fwrite($file," email :");
 fwrite($file, $email ."n");
 fwrite($file," message .:");
 fwrite($file, $message ."n");
 fclose($file);
 }
