In my application I have two tables
orders:
order_id
order_number
products:
product_id
product name
order_id(foreign key)
and in my phpmyadmin I chose order_id to display as order_number but when I render the view associated with products it displays order_id. is there any way that it can order_number instead of order_id?
According to your question, enough adding the following line in the products controller, before rendering of course.
$crud->set_relation('order_id','orders','order_number');
Yes, by configuring the Relation view you can select which column is displayed here.
From the products table, go to the Structure tab, then the Relation view sub-tab:
Set up the relation as so:
Alternatively, use the Designer tab from the database level to do the same:
(hint: I think Designer is generally easier).
Next, from the orders table go to the Relations view and find "Choose column to display" about halfway down the page; pick order_number there so phpMyAdmin knows which column you wish to display.
One last step -- back on the products table, in the Browse view, expand the Options area part way down the page. Toggle the radio button to Display column for relations and press Go.
Now when you Browse the products table, the order_number is displayed instead of the order_id.

I have 2 tables in the Database.
One contains a list of Inventories with name, creation date and ID.
The second table contains individual products, and one column here contains IDs from the Inventory List table.
I write all inventories from the inventory list to the Frontend. There is a detail button next to each listed inventory and after clicking it I need to list all the products with the corresponding inventory ID.
But somehow I can't figure out what to use for it?
Could you please advise me what such a query should contain?
On my website, I have a users table and industry table and industry_overview table. industry_overview contain the overview data of an industry.
I want to have a "Add to Cart" function where user can add the overview detail such as value chain, market share and market price into their cart list.(Cart list item will eventually be merged and generate a report out in pdf form)
May I know what is the simplest way I could get something like that done? I've thought about this but I can't seem to find a solution or idea.
I don't need a ready-made script, just any idea that could get me working then will be great! (Also if you already have an example of such function, I'd be more than happy to have a look at it).
Thanks in advance!
Update:
Industry overview table has 5 column:
overview_id
industry_id
value_chain
market_share
market_price
I would do it using carts and cart_items tables:
carts
=====
- id
- user_id
cart_items
==========
- id
- cart_id
- industry_overview_id
- column
If you want a user to have multiple simultaneous carts you can add a name column, which the user can change.
Any data point (column in industry_overview) selected by the user will result in an entry in the cart_items table.
However, with this method a user's cart items will automatically be "updated" if the value of the overview item changes. If you don't want this you could save the exact values from industry_overview into the cart_items table, either instead of or in addition to the id.
I want to write a method to save the history of changes in the table. I have three tables (products, articles and categories). When a user makes a change, for example in the product name. I want to display a message at the product, example: User Jack change the name of product with "ball" on the "ball2016."
I came up with that I created new pivot table "history_products" wherein the columns will: "user_id", "products_id", "created_at" and "updated_at". This table will be connected with table products. I want to used this trigger. You think it's a good idea or in a Laravel can do it in an easier way??

I have one Category List user will select a category from the list if user didn't find a category in the list, then he will select "other" option and it will display a text box there user will enter a new category name. This newly added category will go for approval to Site Admin till then it should be mentioned as "Uncategorised".
So my question is how to achieve this using a mysql table should I create a new table as uncategorized category or should I add one extra column to category table as "isApproved". As the solution should be for both add and edit of new category.
As you described
Admin must approve newly added category.
To acheive that you definitely will have a field status or something like that to check if this category is approved or not. You can simply use that field. If it is not active, it is "Uncategorized.
A more flexible way than adding one isApproved (or rather a more generic name like status) column to your table is to create a whole new temporary table. There are number of reasons why this is the better approach:
You can save diagnostical information like who created this category, when did he create it, and so on.
You separate your logic: An unapproved entry is, simply put, a temporary one. Approving it is nothing more than moving it over to your categories table and thus making it permanent.
Your categories table doesn't get clustered with unnecessary entries.
i have made a static drop-down menu for my e-commerce website. i have various categories and then sub categories.
my main tabs are, "CLOTHES", "FOOTWEAR", "ACCESSORIES" etc.
The clothes tab is divided into two parts one is brand wise and one is type(shirts, jeans, etc.)
Now my question is, if i go to the clothes tab and then click on shirts, how can i traverse and retrieve the records from my SQL table.
I have made the connection with the database, my table name is 'products'. The page to display products is list.php.
I am new to PHP and i know a little bit about this language.
have a pages table and categories table
also have cat_parent in the categories table
Then have a php loop to go through each topmost categories and then subcats and ......... and then pages.
watch it in action this is the site i am working a the moment
First you should have categories & sub categories in single 'categories' DB table.
In products table, you will have a category_id column as foreign key.
So based on this category_id column, you can retrieve products from your DB.
Also each product in DB should have assigned a particular category.
You have to use AJAX or a Javascript function to achieve this type of functionality. Here is how:
Use an onChange event in your static drop down menu HTML code.
Make a function in a <script> tag to catch the id of selected item.
Pass this id to the PHP file in the URL.
Give your <div> id name in this Javascript code.
After calling the PHP file catch the id from get method and pass it to the query.
You can get the desired result.
