Here is the solution to fix your PHP post to TXT
HTML
<div id="signupform" class="sb-search clearfix">
<form method="post" id="contact" class="clearfix" action="comingsoon/php/formfix.php"> <!-- I remove name="email"-->
<input class="sb-search-input" placeholder="Enter email ..." type="text" value="" name="email">
<input class="sb-search-submit" value="" type="submit" name="email1">
<button class="formbutton" type="submit"><span class="fa fa-envelope-o"></span></button>
</form>
</div>
In your formfix.php should be like this.
<?php
if(isset($_POST['email']) && isset($_POST['email1'])) {
$data = $_POST['email'] . '-' . $_POST['email1'] . "\n";
$ret = file_put_contents('json.txt', $data, FILE_APPEND | LOCK_EX);
if($ret === false) {
die('There was an error writing this file');
}
else {
echo "$ret bytes written to file";
}
}
else {
die('no post data to process');
}
?>
And you will get this result
I already do a test and it's work
Take a note please be aware on file location. And json.txt path must be at formfix.php .

Maybe my English is not good, but I will try to explain is to you as my best.
You should alter your HTML like this:
<div id="signupform" class="sb-search clearfix">
<form method="post" id="contact" class="clearfix" action="/comingsoon/php/formfix.php">
<input class="sb-search-input" placeholder="Enter email ..." type="text" name="email">
<input class="sb-search-submit" type="submit" >
</form>
A name of this "submit" isn't necessary。And so is the form。
Then，your PHP file should look like this:
<?php
if(isset($_POST['email']))
{
$email = $_POST['email'];
$file = fopen("/comingsoon/json.txt",);
fwrite($file,$email);
fclose($file);
print_r(error_get_last());
}
?>
Because the data that post to your server is only "email".
Good Luck to you!
