PHP write to text file from input [duplicate]

Question

I have the following code

<div id="mailbox">
  <form action="verification.php" method="post">
  <input placeholder="Enter your email" type="mail" name="name" style="width:270px; 
   height:42px; border: solid 1px #c2c4c6; font-size:16px; padding-left:8px;" />
</div>
<div>
  <form action="verification.php" method="post">
  <input type="submit" id="button2" value="Next" />
</div>

I want if a user put an input in the enter your email placeholder - it will save the input into a text file.

I have no idea what code I need to write in verification.php. I have 2 days knowledge in PHP.

I want every input a user put in the form, will be saved to user.txt file on my machine.

Thank you

verification.php does not exist yet since I don't know how to store data in it :) — user347977

I would do something like this:

First change your HTML to:

<div id="mailbox">
  <form action="verification.php" method="post">
    <input placeholder="Enter your email" type="mail" name="name" style="width:270px; height:42px; border: solid 1px #c2c4c6; font-size:16px; padding-left:8px;" />
    <input type="submit" id="button2" value="Next" />
  </form>
</div>

Then, verification.php (make sure you have all error reporting on)

<?php
if (!ini_get('display_errors')) {
    ini_set('display_errors', '1');
}
ini_set('error_reporting', E_ALL);

if (isset($_POST['name'])) {
    echo 'Data received, writing to file <br/>';
    if (!file_put_contents('/path/to/filename', $_POST['name']."\n", FILE_APPEND)) {
        echo 'Sorry! unable to write to the file specified';
    } else {
        echo 'data written to file';
    }
}

Hi Kamrul,Thanks for the tip in the HTML! I've edited verification.php to look like: <?php if ($_POST) { file_put_contents('/var/www/html/users.txt', $_POST['name']."\n", FILE_APPEND); } But still not working

did you get any error ?

Hi, nope, blank page

Kamrul Khan Over a year ago

can you confirm if you have error reporting on from your php configuration ? apache needs to have permission in the directory you specified.

Hi, I've changed verification.php to:

<?php if (!ini_get('display_errors')) {     ini_set('display_errors', '1'); } ini_set('error_reporting', E_ALL);  if (isset($_POST['name'])) {     file_put_contents('/tmp/mydata.txt', $_POST['name']."\n", FILE_APPEND); }

Also, i've checked in PHP.INI that display errors is On. Still blank page and no data written into /tmp/mydata.txt
