从我的数据库中的复选框保存值

Question

I am trying to store the values from checkboxes inside my database. So far, I was only able to store the last checkbox choice. Afterwards, I tried following someone's example, but I got so confused. How could I ensure that all my data is being stored inside the database?

In my table, my column which I want to contain the information is named "categories". As for the rest, it is below (2 of them only)

<tr>
    <td><input type="hidden" name="categories" value="categories">Categories</td>       

        <td>
            <div class="checkbox";>
                <label class="checkbox_label">
                    <input name="cats" value="Accessoires" type="checkbox" class="checkbox1"/>
                    Accessoires
                </label>
            </div>

            <div class="checkbox";>
                <label class="checkbox_label">
                    <input name="cats" value="Mobilier de bureau " type="checkbox" class="checkbox1"/>
                    Mobilier de bureau 
                </label>
            </div>
    </td>
</tr>

This is the code I tried following:

$box=$_POST['box'];
$ledlamps = $_POST['ledlamps'];

$str = $ledlamps . ": " . implode(", ", $box);

And so I ended up with this:

$cats = $_POST['cats'];
$categories=$_POST['categories'];

$str = $categories . ": " . implode(", ", $cats);

I do not have sufficient privileges to add a comment to the previous answer attempt but what @Erman Belegu was saying is right, cats[] should do the trick. Here is the code.

The HTML

<tr>
    <td><input type="hidden" name="categories" value="categories">Categories</td>       

        <td>
            <div class="checkbox";>
                <label class="checkbox_label">
                    <input name="cats[]" value="Accessoires" type="checkbox" 
                      class="checkbox1"/>
                    Accessoires
                </label>
            </div>

            <div class="checkbox";>
                <label class="checkbox_label">
                    <input name="cats[]" value="Mobilier de bureau " 
                        type="checkbox" class="checkbox1"/>
                    Mobilier de bureau 
                </label>
            </div>
    </td>
</tr>

<input type="submit" name="submit" value="submit"/>

The only thing I added was the submit button so I could only do something in the php when submit is clicked, here is the same php code.

<?php

$cats = array();

    if(isset($_POST['submit']))
    {
        if(isset($_POST['cats']))
        {
            $cats = $_POST['cats'];
        }
        $categories= $_POST['categories'];

        $str = $categories . ": " . implode(", ", $cats);
        echo $str;
    }

?>

If you select something and click echo you will see categories: and whatever you selected.

Hope this helps or perhaps I did not get exactly what your problem was in the first place.

Thanks.

The name of input shoud be name="cats[]" . In these form you will get array of value that you checked.
