How to read many checkboxes with the same name

[PLAnt]

Hello ppl,

How can I read many checkboxes with the same name, using PHP?

An example.....

<input name="my_checkbox" value="1">
<input name="my_checkbox" value="2">
<input name="my_checkbox" value="3">

and now I want to read all the values of the variable $_POST[my_checkbox], but I can only get the value of the last checkbox. 🙁

How can I solve this problem please....

🙁

Make the checkboxes an array by changing the name to my_checkbox[]. Then when you read them, you can just read through the array.

Thank you, but I know that, but If I use it, I will have problems programming with Javascript.
Is there any other way to do it?

Basically no. Each variable will overwrite the previous one. Its the same as saying

<?

$number=1;
$number=2;
$number=3;
$number=4;
$number=5;

echo $number;

?>

All it will output is the last number entered. If you want to call them the same they will overwrite each other.

What does the javascript do that needs them to all be named the same? I would have thought that javascript would have problems, or at least odd behaviour from them being named the same.

Well, I guess you could number them
<input name="my_checkbox1" value="1">
<input name="my_checkbox2" value="2">
and so on...
Then on the next page, loop

for($i=1;$i<yourhighestnumber;$i++) {
   if(isset($_POST['my_checkbox'.$i])) {
      // you get the picture
   }
}

Seems like a useless hack though
