  1. I figured it out. I had to put id here not uidUsers $sql2 ="SELECT * FROM users WHERE uidUsers='$id'"; $sql2 ="SELECT * FROM users WHERE id='$id'";
  2. Hello mac_gyver, Thank you for the input. The comments are being saved in DB now. I included the functions page in the page where the form is so it has access to that function. The comments are being saved in the DB now, but I can't retrieve them still =(
  3. Ok, the data is going into the DB now but I still cannot retrieve it
  4. Hello everyone, I am trying to submit a comment in a comment box and send it to the DB but is not happening. The connection is good as I am logging in and all but no data is sent to the DB when I post the comment. It doesn't show in my comment section either. Form <!--comment section--> <?php if(isset($_SESSION['id'])) { echo "<form method='POST' action='" . setComments($conn) . "'> <input type='hidden' name='uidUsers' value='".$_SESSION['id']."'> <input type='hidden' name='posted' value='" . date('Y-m-d H:i:s') . "'> Comments: <textarea rows = '5' cols = '15' name='body'></textarea><br><br> <button name='commentSubmit' type='submit'>Comment</button> </form>"; }else { echo "Log in to comment!"; } getComments($conn); Function to set and get comments function setComments($conn) { if (isset($_POST['commentSubmit'])){ $user_id = $_POST['uidUsers']; $body = $_POST['body']; $posted = $_POST['posted']; $sql = "INSERT INTO comments (uidUsers, posted, body) VALUES ('$user_id', '$posted', '$body')"; $result = mysqli_query($conn, $sql); } } function getComments($conn) { $sql = "SELECT * FROM comments"; $result = mysqli_query($conn, $sql); while ($row = $result->fetch_assoc()){ $id = $row['uidUsers']; $sql2 ="SELECT * FROM users WHERE uidUsers='$id'"; $result2 = mysqli_query($conn, $sql2); if($row2 = $result2->fetch_assoc()){ echo "<div class='comment-box'><p>"; echo $row2['uidUsers'] . "<br>"; echo $row['posted'] . "<br>"; echo nl2br($row['body']); echo "</p></div>"; } } }

  6. Thank you for your input. I still get the same result.
  7. <?php $a = array(-15, 3, 5, -1, -15); $b = array(1, 3, 5); function lowest_int ($c){ print_r(array_keys($c, min($c))); } print_r(lowest_int($a)); print_r(lowest_int($b)); ?> Hello guys the out of my code should be [0] => -15 [4] => -15 for the first array and [0] => 1 for the second array. However. this is my output: Array ( [0] => 1 [1] => 4 ) Array ( [0] => 0 ) Any ideas what am doing wrong? Thank you so much in advance!
  8. Thank you so much for your input. I was able to get this working 😃
  9. I am trying to create a code where the user enters the zip code and if found in the database, a location will be retrieved. I am getting two undefined variables as errors. I am still learning the POST and GET method and I fear that is where I am getting something mixed up. I have also attached an image of my DB. Thank you so much any input is greatly appreciated. Notice: Undefined variable: address in C:\xampp\htdocs\index.php on line 53 Notice: Undefined variable: zip in C:\xampp\htdocs\index.php on line 54 index.php file code: <?php include ('header.php'); include ('function.php'); ?> <div class="wrapper"> <div> <?php echo'<form method="POST" action"'.getLocations($conn).'"> <input type="text" name="zip" class="search" placeholder="Zip code"><br> <button type="submit" value="submit" id="submit">Submit</button> </form>'; getLocations($conn); ?> </div> </div> <div> <!--foreach($zip as $zip) : --> <?php echo $address['address']; echo $zip['zip']; ?> </div> function.php file code: <?php $dBServername = "localhost"; $dBUsername = "root"; $dBPassword = ""; $dBName = "addresses"; // Create connection $conn = mysqli_connect($dBServername, $dBUsername, $dBPassword, $dBName); // Check connection if (!$conn) { die("Connection failed: " . mysqli_connect_error()); } function getLocations($conn) { if (isset($_POST['submit'])){ // Validate Zip code field if (!empty ($_POST['zip']) && is_numeric ($_POST['zip'])) { $zip = (int)$_POST['zip']; $query = "SELECT * FROM locations WHERE zip = '$zip'"; //get the results $result = mysqli_query($conn, $query); //fetch the data $zip = mysqli_fetch_all($result, MYSQLI_ASSOC); var_dump($zip); mysqli_free_result($result); //close connection mysqli_close($conn); } } }
