PHP - Header Declaration For Unavailable Product
I am wonrdering what the best type of http header to declare for a product page the is trying to display a product that is either not active at the moment or no longer available. Basically is google was trying to reach product-details.php?product-id=50 but that $_GET didn't return any results from the DB, I typically have a message that says "That product does not exist or is unavailable at this time.", but it's just a else{} that is showing that and not declaring any http error like 404.
I don't think 404 would be appropriate though cause I don't want it to be can't find type error I think since the product might just be inactive at the moment. Maybe I am wrong and it should be a 404 error, or is there a more appropriate error to use? I am mostly concerned about the http header for search engines since the message I display is more than enough for users on the page.
Similar TutorialsI have some difficulty identifying why the session variables' values have disappeared in my PHP code. When I try to echo their values, nothing shows up and when I try to compare the values, it does not work.
There are no error messages to indicate something has gone wrong?
Can someone assist?

Why I'm getting this error? I think there is something wrong with CookieAuthanticator.php file but unfortunately I could not find it Edited May 24, 2019 by Rommeo Is it possible to perform type declaration which allows either an integer or a string digit (i.e. ctype-digit) instead of the following?
function someFunction(int $id){}
Looking at functions.arguments.type-declaration, I expect not. If not, would you recommend type casting before calling the function or removing type declaration from the function and performing the check manually within the function and throwing an applicable exception? Thanks Hello everyone, I'm just starting out with PHP as I need to create an online bookstore for a school project. I'm working by a magazine which should teach you exactly how to do this using PHP, but I've had a bunch of problems with the code they use and I don't really know what's going on. Anyway, this looks really simple and basically what it does is allows you to post a comment on a book, then returns you to the book's page. Problem is, I'm getting the Header may not contain more than a single header, new line detected. error and I can't figure out why. I've tried researching into the matter but all the cases I found had to do with returning to an url, which is not my case. Anyway, here's the snippet of code: The form: Code: [Select] <div style="width:400px; border:1px solid #ffffff; background-color:#F9F1E7; padding:5px"> <b>Adauga opinia ta:</b> <hr size="1"> <form action="adauga_comentariu.php" method="POST"> Nume: <input type="text" name="nume_utilizator"><br><br> Email: <input type="text" name="adresa_email"><br><br> Comentariu: <br> <textarea name="comentariu" cols="45"></textarea><br><br> <input type="hidden" name="id_carte" value="<?=id_carte?>"> <center><input type="submit" value="Adauga"</center> </form> </div> The script adaugare_comentariu.php: Code: [Select] <?php ob_start(); include("conectare.php"); $numeFaraTags=strip_tags($_POST['nume_utilizator']); $emailFaraTags=strip_tags($_POST['adresa_email']); $comentariuFaraTags=strip_tags($_POST['comentariu']); $sql="insert into comentarii (id_carte, nume_utilizator, adresa_email, comentariu) values(".$_POST['id_carte'].", '".$numeFaraTags."','".$emailFaraTags."','".$comentariuFaraTags."')"; mysql_query($sql); $inapoi="carte.php?id_carte=".$_POST['id_carte']; header("location:urldecode($inapoi)"); ob_end_flush(); ?> conectare.php connects to the mysql database. $inapoi is the variable which returns the user to carte.php (the book he posted a comment on), where id_carte is the book's unique id. I'm getting Header may not contain more than a single header, new line detected on line ten, which is the header line. Can anyone help me? I've been stumped on this for a few days now and I've just let it pass and started working on other bits, but it's bugging me too much and I'd like to fix it.

I am rolling my first-ever e-commerce site, and could use some help on designing a product gallery. My site will be selling books and guides, and similar to what you might see on Amazon or Barnes & Noble, I want to create a product gallery which displays all products for a given category. For simplicity, let's say that I am only selling paper books, and that is what I want to display - so for the purposes of this conversation, no need to filter on product type. When a user clicks on the product catalog, I was thinking of simply displaying all products (e.g. eBooks) in gallery containing thumbnails in a grid arrangement. The user would click on the thumbnail - which would be the cover of the book - and then be taken to a product page which would have all of the details, including: a larger thumbnail of the book, book title, description, price, author, etc. I suppose I could have a test title and description below each thumbnail? Anyways, I am a little uncertain of how all of this would work from a technical standpoint?! I guess I was thinking that each thumbnail would have a link behind it, which would then load my "product_details.php" page AND pass along something like a "ProductID" in the URL, so that my product_details.php" script could query my database and pull up the book's details. How does that sound? I look forward to hearing what you PHP gurus have to say!! 🙂

I'm working with php and MySQL and I am a newbie coder trying to learn on my own.

Short Description: currently users of the application I am hired to develop have two steps to do when using the app:
1. Select a Product Line (A, B, C, D)
2. Select input parameters for that product line - all product lines have simlar "Main" input parameters, but also each line has its own special features that can be selected.
3. Selections for that product line are shown - the result is a long table or options for that particular product line. Things like price, discounts, product specifications, etc.
What the users want now is this:
1. Select input parameters (not sure how to handle individual product lines special parameters yet)
2. Selections for all product lines are shown
The code base is legacy code, with code thrown around everywhere. One idea me and my coworkers have been considering is a complete rewrite, since it will help us with writing tighter code, and do what the customer wants. But that will also take time, and there is no spec. The spec is in the code mess.
Another one is I am considering now is a "merge". Somehow merge the product lines, since we have the separate product modules (A, B, C, D), there must be a way to consider maybe extending one to include the others, or somehow get me to the end result -- allow users to see selections for all product lines.
Do you have any experience, any suggestions on how to do this? I know this needs details, and details are in my code that you don't see, and most likely won't have the time to read and understand anyway.
But I am looking for any ideas or encouragement though that may help. And my question is -- is there any kind of procedure or technique or something to deal with the problem I am facing -- merging several separate yet similar modules into one single merged module. How do I approach this, what are some things that could help, etc. That's what I'm looking for.
i have shopping cart i need to make the related product section in which i can show the related product when user view the product details. do i need to create any table for it ? please guide me about it. thanks Hello. I just created a product gallery containing thumbnails of items that I will be selling. When a user click on on of the thumbnails, I want a product details page to appear with more details about the chosen product Could use some feedback if I am going about things the right way... Step 1: User goes to my gallery located he www.mysite.com/store/product-gallery.php Step 2: System displays a page of thumbnails representing items that I am selling. Step 3: User click on a given thumbnail which is a hyperlink to: www.mysite.com/store/products/4571 Step 4: System rewrites the URL as such: www.mysite.com/store/products.php?sku=4571 Step 5: System queries MySQL and retrieves record for sku 4571 Step 6: System displays product details for the chosen item in Step 3 which is sku 4571
How does that sound?
I am wanting to do something similar to this: http://www.dimarzio.com/pickup-picker My question involves the concept rather than any specific code on how to execute this. For example, we are selling violins and we want the user to input info about their playing style, and give them the three best violins based on their entry. This is the data I've been given: Level: Beginner Intermediate Advanced Soil, Kreisler, Gibson Soil, Kreisler, Ysaye, Cremonese, Gibson Cannon, Soil, Ysaye, K.Joseph, Keifetz Bowing Style: Soft Medium Hard Soil, Medici, Kreisler Soil, Medici, K.Joseph, Ysaye Cannon, Kreisler, Soil, Heifetz Musical Style Classical Fiddle Rock Ysaye, Soil, Provigny Medici, Ysaye, K.Joseph Kreisler, Diable, Vieuxtemps Desired Tone: Bright Balanced Dark Soil, Medici, Provigny Kreisler, Soil, Ysaye Cannon, Diable, Plowden So if the user inputs Expert, Hard, Rock, and Dark I will data sets of violins consisting of: Cannon, Soil, Ysaye, K.Joseph, Heifetz // Cannon, Kreisler, Soil, Heifetz // Kreisler, Diable, Vieuxtemps // Cannon, Diable, Plowden Out of those I need to output the user the three best choices for them. Cannon is listed in 3 out of the 4, so that has to be #1. Now there are three more violins that match two of the criteria. The Soil, Kriesler and Diable. In order to drill that down to two choices, I would think the questions would have to be ranked according to importance. For instance Tone is most important, followed by bowing style, musical genre, and skill level. Based on that ranking, the program should choose the Diable and Kreisler. I am not entirely sure how to approach this. Since this data will not change frequently, should this even get the database involved? Should the info just be stored in a multi-dimensional array? Once the data is in an array, whether from the DB or not, how should I go about programming the logic to examine the arrays in order of importance and grab the violins that are most relevant? Any help is much appreciated! I figured this was going to be easy, until I actually started thinking about it! I have made a custom post type for products, and am using a custom taxonomy for the product categories. The thing that I am wondering about is that sometimes a product category is a parent, and sometimes a child, but sometimes both. For instance, if you have a top level category named shoes, then you might have a sub category named Nike. However, Nike also has shirts, so you could say that shoes and shirts were both subcategories of Nike. Do you know what I'm saying? It's like there is no real parent to child relationship, but they are both parents and both children of each other. How do you handle this type of situation?
I got a problem guys, when I wanna add a product to my cart it wont add the product to my cart.
