Hi, I've been scratching my head for a while now about how to do this, I'm relatively new to php and mysql and perhaps foolishly taking on creating a user area for a website.  I have everything else working, all of my register account functions and confirmations and all of the login scripts etc. 

I have created a profile page which returns various information to the user (this bit works fine) and I've got some nice show/hide toggles running with some javascript/css but my intention is to allow the user to change thier information (e-mail address, contact phone number and also whether they are subscribed to the e-mail list), it also displays any support tickets or messages.

So after the long intro, here's what I'm struggling with...  I have a form in a visibility toggled <div> which submits a 'change_email' script, so a user wants to change their e-mail, clicks on change, the <div> appears, they bang in the new e-mail and hit submit.

My php script appears to work (because it doesn't throw up any errors), until you realise that actually it's not updated the record in the db...

I'm using mysql_query("UPDATE users SET email='$new_email' WHERE username='$user'");

Do I need to setup variables for all of the information in the db (name, username, password, email, contno etc etc) and include them in the command to get it to work or should that just pick the correct record and then update it? If that is the case is there a way I can include 'blank' variables so I don't have to set them all up...

e.g.  mysql_query("UPDATE users SET user='',password='',email='$new_email', etc WHERE username='$user'");

Many thanks in anticipation

I have this loop on a shorturl website i own that selects domains from my website and lists them in a dropdown list where users can select one domain to use as url shortener.

The problem is that when a users selects and entry from the dropdown list this created only the [[[main_url]]] entry from the database table bellow can be used. When someone selectes "coolartistname.site.com the submit button cannot be pressed. in other words it's not adding the SELECTED attribute other than the [[[main_url]]] domain.

Can anyone see on the code bellow why this would happen?

When i echo $shortUrlDomains it's just saying "Array" and $_REQUEST['shortUrlDomain'] shows nothing.

**Index.php**

    // get base urls
    $shortUrlDomains = getShortUrlDomains();
    
        <?php
        foreach ($shortUrlDomains AS $k => $shortUrlDomain)
        {
        
            // active domains only
            if (($shortUrlDomain['premium_only'] !== '1') && ($shortUrlDomain['premium_only'] !== $Auth->id))
            {
                continue;
            }
        
            echo '<option value="' . (int)$k . '"';
        
            if (isset($_REQUEST['shortUrlDomain']))
            {
                if ($k == (int)$_REQUEST['shortUrlDomain'])
                {
                    echo 'SELECTED';
                }
            }
        
            echo '>';
        
            echo $shortUrlDomain['domain'];
        
            if ($disabled == true)
            {
                echo ' (' . safeOutputToScreen(t('unavailable', 'unavailable')) . ')';
            }
        
            '</option>';
        }
        echo '</optgroup>';
        ?>

FUNCTIONS.PHP

    function getShortUrlDomains()
    {
        // if we already have it cached
        if(defined('_SETTINGS_SHORT_URL_DOMAINS'))
        {
            return unserialize(_SETTINGS_SHORT_URL_DOMAINS);
        }
        
        // get connection
        $db  = Database::getDatabase(true);
        
        // load from database
        $domains = $db->getRows("SELECT id, domain, premium_only, status FROM url_domain ORDER BY premium_only ASC, id ASC");
        
        // organise and replace site url
        $rs = array();
        foreach($domains AS $domain)
        {
            if($domain['domain'] == '[[[main_url]]]')
            {
                $domain['domain'] = _CONFIG_SITE_FULL_URL;
            }
            $rs[$domain{'id'}] = $domain;
        }

**MYSQL DATABASE**

    url_domain (id, domain, premium_only, status, date_created, owner) VALUES
    (1, '[[[main_url]]]', 0, 'enabled', '2019-03-02 08:13:00', 1) 
    (14, 'coolartistname.site.com', 6, 'enabled', '2020-04-18 19:21:59', 6);

 

I cant get my head around this. I m trying to add product attributes into this script.

I have products tables and product_extras

product.id and product_extras.id are same. How can I add this to cart. Is there any easy way to do this.

Any help would be  much appreciated!

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

I have a task that seems to be complex.   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.

Hello.  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 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!

My table looks like this..

`guns_id` int(255) NOT NULL auto_increment,
  `guns_name` varchar(255) collate latin1_general_ci NOT NULL,
  `guns_price` int(255) NOT NULL,
    PRIMARY KEY  (`guns_id`)

I want to add a product key that is unique through out the whole database as I have other products other than guns aswell.

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?

 

Hi.  This question is building off of things you all helped me with earlier in my other two threads.  (I go no sleep last night, so sorry if my thinking is a bit off!)

Now that I know how to create a gallery page - as far as HTML goes - to display a listing of free add-on items you get when you subscribe, I need to extend those concepts to my next project.

I need to create a product catalog page for my e-commerce site.  (Not sure if there is a better name?)

This is the page you would see if you went to an e-commerce site and started shopping.

At the top of the page would be my company mast.  And beneath that, on the left side of the screen would be a menu listing different areas of my online store.  And to the right, would be the area where you see the actual products.  (And I would be using the same techniques to display items on the right hand side as I did in my earlier gallery.

So here is where I could use some hep with the logic of this page...

Let's say my website is located at www.mystore.com

And in the left menu bar, I have these categories:  Music, TV Shows, Movies, Gear

And in the right pane I want to display items for the chosen section.

So if you chose "Music", I am thinking the hyperlink behind it might read; www.mystore.com/music/   with a mod_rewrite to www.mystore.com?category=music

And then I would have PHP code that would fire when the page is reloaded to www.mystore.com?category=music and it would query MySL and display all music related products in the right pane.

(Note: It is understood I am only using HTML and PHP with no Javascript.)

How does the above approach sound?

 

I am a php programmer but I am not so good with XML files.
For a price comparison website, I need to parse the Amazons XML feed to store product data into the database.

Can anyone please help me to find out such a simple script to parse Amazon XML product feed???
(Actually, I need each product data in array to be stored into the database)

Thank you in advance.
