Really? What I saw in the video you only set the variable like this :
private $alertTypes;
Or maybe I just missed seeing
Ok enough for that part. Still not clear but better than before.
I have one more question. This one is about getAlert()
Consider this line :
if (isset($_SESSION[$alert]))
Is it the session come from this line :
$_SESSION[$type][] = $value;
If not, I need your explanation. Sorry to trouble you, Ben.

Thanks for your reply Still staring at the codes to understand the real process. Hopefully the thing will clicks soon
Ok when we say :
$type = $this->alertTypes[0];
What I understood right now is, we want to replace the $type with $this->alertTypes and put the node 0 to it. Like this :
$type[0]
Am I right?

Hi there,
I'm working on Ben Falk's PHP Login Using OOP & MVC and I need detailed explanation about this function :
function setAlert($value, $type = null) { if ($type == '') { $type = $this->alertTypes[0]; } $_SESSION[$type][] = $value; }
What really the use of the blank array and how it works really?
Hopefully Ben or anybody can explain it deeply because I just a beginner here. Thanks!

I imagine that it is caused by the empty space just after your renderForm function, but before the start of the next code:
<?php } ?> <?php
I believe that empty line is being sent to the browser as a space character, which will cause the header() error when you try to redirect. Try revising those lines to this:
<?php } ?> <?php
or you could just drop the unnecessary closing/opening PHP statements and go with this:
<?php }
Nah! The error all fixed now and I learned something new today
Thanks a lot Ben! You're really the legend here

I believe the line that is causing the issue is here:
if ($firstname == NULL || $lastname = NULL) {
You need to have two "=" next to that last statement, otherwise you are accidentally setting $lastname to null. Try this and get back to me -- it should fix your problem.
Thanks Ben! The error gone already now
One more thing, when I try to add new record, I got this error on records.php
Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\test\crud-mysqli\records.php:42) in C:\xampp\htdocs\test\crud-mysqli\records.php on line 64
Is it because the doctype that I use that cause this error?

I'm home - but don't know php, sorry. I'm sure Ben will help you out as soon as he sees your question - unless on of our other PHP experts beats him to it.
Thanks Andrea to spend your time replying my topic. Although you not answering my question but it's great to see some reply from expert in noob's thread like me
-
Sorry, must have missed seeing this one. I'll take a look.
Thanks Ben, I tried many times to fix this 2 issue here ('header' and 'last name cannot be NULL') but really don't have an idea what's going wrong. Really appreciate your help!

Anybody home? Or do I need edit my question to be more specefic to get answer here?
Thanks

Hello all,
Currently I'm working with Ben Falk's tutorial on PHP CRUD Videos and I got my head spinning with some errors
I'm stuck at video part 5 and below is my code (which I did based on the videos) for your reference (to help me ):
<?php include ('connect-db.php'); function renderForm($first = NULL, $last = NULL, $error = NULL, $id = NULL) { ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title><?php if ($id != '') { echo "Edit Record"; } else { echo "New Record"; } ?></title> <link href="css/style.css" rel="stylesheet" type="text/css" /> <script type="text/javascript" src="js/jquery.js"></script> <link rel="shortcut icon" href="images/favicon.ico" /> </head> <body> <h1><?php if ($id != '') { echo "Edit Record"; } else { echo "New Record"; } ?></h1> <?php if($error != '') { echo "<div style='padding=4px; border=1px solid red; color:red'>" . $error . "</div"; } ?> <form action="" method="post"> <div> <?php if (!empty($id)) { ?> <input type="hidden" name="id" value="<?php echo $id; ?>" /> <p>ID: <?php echo $id; ?></p> <?php } ?> <strong>First Name: *</strong> <input type="text" name="firstname" value="<?php echo $first; ?>" /> <strong>Last Name: *</strong> <input type="text" name="lastname" value="<?php echo $last; ?>" /> <p>* Required</p> <input type="submit" name="submit" value="Submit" /> </div> </form> </body> </html> <?php } ?> <?php if (isset($_GET['id'])) { // editing existing records renderForm(NULL, NULL, NULL, $_GET['id']); } else { // create new record if (isset($_POST['submit'])) { $firstname = htmlentities($_POST['firstname'], ENT_QUOTES); $lastname = htmlentities($_POST['lastname'], ENT_QUOTES); if ($firstname == NULL || $lastname = NULL) { $error = 'ERROR: Please fill in all the required field'; renderForm($firstname, $lastname, $error); } else { if ($stmt = $mysqli->prepare("INSERT players (firstname, lastname) VALUES (?,?)")) { $stmt->bind_param("ss", $firstname, $lastname); $stmt->execute(); $stmt->close(); } else { echo "Error: Could not prepare SQL statement."; } header("Location: view.php"); } } else { renderForm(); } } $mysqli->close(); ?>
And this is the error message I've got :
Warning: mysqli_stmt::execute() [mysqli-stmt.execute]: (23000/1048): Column 'lastname' cannot be null in C:\xampp\htdocs\test\crud-mysqli\records.php on line 59 Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\test\crud-mysqli\records.php:42) in C:\xampp\htdocs\test\crud-mysqli\records.php on line 64
Hopefully someone can help me on this and your help will highly appreciated!
Many thanks!
Array - Need Detailed Explanation
in PHP

Thanks for your explanation, Ben
One more thing to clear and this is because I always see the same variable in your code. So I get confuse whether it is same variable or the other one.
Consider this line
and
Both variable is same which is $value and both is an assignment to the same session (you mention earlier post). So this is just like confuse me a little bit
