You should specify
as array.
Add [] to all names Days and work at php with this like an array.
After it, you can INSERT values at different columns at db, or use implode and save values into one column.
Didn't tested it, but you can try like this. Don't forget to replace mysql with mysqli.
You need to declare the array in the HTML via
Also you can insert multiple items with one query like this
Also keep in mind that mysql_* functions are officially deprecated and hence should not be used in new code. You can use PDO or MySQLi instead. See this answer on SO for more information.

I want to have multiple checkbox values be stored into one field in a database. (Ex. 1, 24,56,100). I am wanting to know how I can make this happen, and how does PHP read these values from the database if I want to call variables in a query?
Basically I am creating a blog app (for fun and experience) and I want the user to be able to change the visibility of each blog post through checkboxes. I know you are probably thinking why don't I just have a visibility field for each blog post. I understand why it is not recommended to do this, but I can't think of any other way to do this. To explain a bit more: I want to attach this application to a CMS I have already built, and basically I have a table with blog posts, and then I want the user to be able to go to different pages within their site and add a blog. Well, what if the user wants to use the same blog on 3 different pages, but only wants certain posts to show on each page. So this is why I am confused right now.

Even though I am not in favor of saving data like that but here is what you can do, if you really want to do it that way. I suggest you have a denormalized table and store your vals there
in your HTML you can have your checkboxes like this (considering you are storing ids of some sort)
Checkbox Update
On you php side you can use function implode to form ids into a string as shown below (considering you are doing a POST)
Where you read from the database you can transform the value from db to an array like this
I hope this helps
Jaspreet ChahalJaspreet Chahalfirst create database:
after that create an html page like that:
after that we have do mysql connect.php
after that we have to create an check.php like that ok
kleopatraThe perfect solution for this is task the creation of normalized table as commented by @OMG and @Michael.
But here is the answer for what you just asked
Store this in MySQL table. You can use LIKE command to query the table and use the explode to get back the ids in array.
Rohan KumarYou're going to want to go through the basics of PHP and MySQL.
Check out tizag.com or w3schools.com, or some other sites (the tutorials are plentiful).
Here's the basics though--and remember this, as it'll help you in your understanding.
MySQL is a database. A database is typically used for storing data.PHP is a programming language. It's typically used for programming.
So, some wonderful developers out there have already taken care of the steps for talking to the database from PHP. All you have to do is establish a connection.
See mysql_connect via W3Schools
Okay, so what you have done here, is you've connected to the database SERVER. You haven't selected a database yet. Think of it like going to a movie theater, you still have to pick a movie to watch.
So, now we connect to our database:
Mysql Update Multiple Columns
See mysql_select_db via W3Schools
Once you've connected to your database, you're ready to grab some information from it.
To do this, you need to create your SQL query.
Something to the tune of:
See the SELECT statement via W3Schools
Depending on how your table is set up, that will get you the list for the current user. I'm assuming that you already have the user's id (or a way to get it), since they have the ability to define their own preferences for the site.
Now that you have the SQL query to get the articles, you need to query the database.
That should get you your list of ID's that you need.
I'll let you figure out the rest. It's pretty straight-forward, and you've got all of the tools that you need now. The only thing you might want to brush up on is explode and foreach.
So, the way you store them is up to you. Look into explode for splitting them up when they're stored that way.
