writing-csv what is wrong with my code? Permission denied

What it suppose to do is to add a line in the people.csv (location root/data/csv/people.csv) from the form(see below) however I get the Warning: fopen(../data/csv/people.csv): failed to open stream: Permission denied in /home/treehouse/workspace/inc/write_csv.php on line 11 line 11 is if (($fh = fopen('../data/csv/people.csv', 'a+' )) !== false) { Please halp!?

this is my write_csv.php file, location root/inc/write_csv

<?php

$new_person = [
  filter_input(INPUT_POST, 'first', FILTER_SANITIZE_STRING),
  filter_input(INPUT_POST, 'last', FILTER_SANITIZE_STRING),
  filter_input(INPUT_POST, 'website', FILTER_SANITIZE_URL),
  filter_input(INPUT_POST, 'twitter', FILTER_SANITIZE_STRING),
  filter_input(INPUT_POST, 'img', FILTER_SANITIZE_URL)
];

if (($fh = fopen('../data/csv/people.csv', 'a+' )) !== false) {
  fseek($fh, -1, SEEK_END);
  if (fgets($fh) != PHP_EOL) {
    fputs($fh, PHP_EOL);
  }
  fputcsv($fh, $new_person);
  fclose($fh);
}
header('location: /people.php'); 

this is the add_person.php page, location root

<?php
/**
 * Form for adding more people to the csv file
 * first,last,website,twitter,img
 */
$title = 'Add Person';
require 'inc/header.php';
?>
<form method="post" action="inc/write_csv.php">
    <div class="form-group input-group-lg">
        <label class="control-label" for="first">First Name</label>
        <input class="form-control" type="text" name="first" id="first" />
    </div>

    <div class="form-group input-group-lg">
        <label for="last">Last Name</label>
        <input class="form-control" type="text" name="last" id="last" />
    </div>

    <div class="form-group input-group-lg">

        </div>
    </div>

    <div class="form-group input-group-lg">
        <label for="twitter">Twitter</label>
    <div class="input-group input-group-lg">
        <span class="input-group-addon" id="twitter-addon">@</span>
        <input class="form-control" aria-describedby="twitter-addon" type="text" name="twitter" id="twitter" />

        <label for="img">Image</label>
        <input class="form-control" type="text" name="img" id="img" placeholder="http://" />

Hi there! Have you tried changing the permissions of the csv file before fopen()? Have a look at: http://php.net/manual/en/function.chmod.php Hope it helps!

I'm having the same issue. I went back and looked at the notes on file permissions then checked it using fileperms() - the response was "rw-r--r--" - so that suggests that I do have read and write permission (unless I'm not the owner??). Nevertheless I tried updating it anyway using chmod() as Victoria suggests. Result was "chmod(): Operation not permitted".

Hoping someone chimes in with an answer :-(

Using your console type the following command

chmod 777 data/csv/people.csv
