Where's your logic to save the text file? Also, why are you using a text file? Is it for documentation purposes or tracking or logging? — ctwheels, Jun 27 '17 at 16:46

Here is what your HTML should look like:

<form action="**php file path goes here**" method="POST">
    <input name="field1" type="text" />
    <input name="field2" type="text" />
    <input type="submit" name="submit" value="Save Data">
</form>

and your php file:

<?php
if(isset($_POST['field1']) && isset($_POST['field2'])) {
    $data = $_POST['field1'] . '-' . $_POST['field2'] . "\n";
    $ret = file_put_contents('/tmp/mydata.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');
}

Note: This answer is from PHP write file from input to txt so please check before asking again.

Can I add some details? Don't name the Submit button Submit. Use names like name="subSavetoFile" and add an id value too, like id="subSavetoFile". You may end up with multiple submit buttons and you'll want your JavaScript form check functions and your PHP logic to discern what you want to do and check.

Don't forget to add PHP data checking protection like intval(), floatval(), mysqli_real_escape_string(), filter_var() or have a list of approved values to winnow out potential attacks.
