  1. I am new at php. I am trying to loop a number in each click of a button. See attached picture for reference. 1 should iterate after the click of the button and will stop to iterate when it gets to 5. Here is my code: <!DOCTYPE html> <html> <body> <div>Question <?php $num = 5; $n = 1; $n <= $num; echo $n; ?> of <?php echo $num;?></div> <form method="post"> <button id="button" class="button" value="add" name="add">Click</button> </form> </body> </html>
  2. How do we easily get rid of people who register but do not activate their account? I just found out that I cannot schedule an event in the database because I am on a shared web hosting plan. I am seemingly getting a lot of "fake" registrants that are taking up space.

  7. I have this stored procedure that has 2 parameters, the first one is the cartId(which is the IN) and I have the newOrderId(which is the OUT). Now, I know that the inCartId is the cart id which will come from the form or whatever means the cart is been access but I don't understand the OUT newOrderId since that is what MySQL will return. Now, in the PHP calling this Stored procedure, it will look like this. $sql = 'CALL create_order(:cart_id, "What will be here")// The cart_id is what PHP will pass to MySQL, but what will be passed to the 2nd argument since does not before hand what MyS

I am set up to use PHP 7. // Query the database: $q = "SELECT user_id, first_name, user_level, pass FROM users WHERE email='$e' AND active IS NULL"; $r = mysqli_query($dbc, $q) or tri

  14. For some reason the images I am uploading to my uploads folder are just showing as blank, the files are there but it is not showing them as images. It is written that the type of file it is is just File. and it shows the path to the image D:\xampp\htdocs\uploads. My add_print.php is just fine as far as I can tell. I tested it with the script written by Larry in the working files for this book, it doesn't work either. I checked my permissions for my uploads folder and they look fine too. I am thinking the problem is maybe because no Mime type is specified for the images being uploaded. If
