Simple php checkbox problem

[Rifts]

hey guys

 

I think I have a pretty simple problem I just cant seem to figure out.

 

I have an html form with 10 checkboxes

 

when I submit the form it echos all the inputs (name, address etc.)

 

the problem is I get "Notice: Undefined index: chx1" for each checkbox if it it not checked

but if the box is checked there is no error.

 

what do I need to do so the checkboxes are not required?

 

thanks

 

oh btw the checkboxes are NOT dynamic

You should check if the variables exist before referencing them otherwise. Do this with the isset method.

 

isset($_POST["variables"]);

Yes, and you can also create an array of checkboxes so that you only operate on the ones that are set:

<input type='checkbox" name="check[1]" value="something">
<input type='checkbox" name="check[2]" value="something else">

 

Then:

foreach($_POST['check'] as $key => $value) {
   //do stuff with $key and/or $value
}

I you do your inputs the way I showed, then you would remove all the  $chxN = $_POST['chxN'] and replace all of your echo $chxN with:

 

foreach($_POST['check'] as $chx) {
   echo $chx;
}
