Question

I would like to get more checkbox content into my database. It means that I have categories of php, java, html and css but I click on php and html, so it must be the two into in the same database that is within the database category.

It looks like this when I lie in the database:

$kategori = $_POST["kategori"];

How it looks when the user must select a category such as php and html to the database:

<input type="checkbox" name="kategori[]" value="<?php echo $tekst;?>"/>
<?php echo $tekst;?>

Right now when I put it into the database writes just "array" and nothing else even though I have selected two categories to the database.

How do I put multiple categories into the database same time?

Answer 1

say for example you have 2 checkbox:

<input type="checkbox" name="kategori[]" value="1"/>
<input type="checkbox" name="kategori[]" value="2"/>

so when you submit the form in the submit page the data in the variable is $_POST["kategori"] is structure as:

Array([0] => 1
      [1] => 2
      ); //which you could see by executing the code print_r($_POST["kategori"]);

So in order to put it into the database you can change it into a comma seperated string and insert under a single field in the database table

$kategori = implode(",",$_POST["kategori"]); //which will give the output "1,2" when you do echo $kategori;

I hope this can be of some help
