</div>

In my form I have three groups of checkboxes. When someone selects no box in one group it gives back and echo error message:  
[COLOR=“Red”][SIZE=“2”] Warning: Invalid argument supplied for foreach() in /home/jimmyweb/public\_html/mailer.php on line 15

Warning: Invalid argument supplied for foreach() in /home/jimmyweb/public\_html/mailer.php on line 18

Warning: Invalid argument supplied for foreach() in /home/jimmyweb/public\_html/mailer.php on line 21

Warning: Invalid argument supplied for foreach() in /home/jimmyweb/public\_html/mailer.php on line 24

Warning: Invalid argument supplied for foreach() in /home/jimmyweb/public\_html/mailer.php on line 27[/COLOR][/SIZE]

here is my php:

```php
echo "Data has been submitted to $to!";
mail($to, $subject, $body);
} else {
echo "blarg!";
}
?>

```

how can I change it so it won’t give the message? do I change the {else}  
echo or is there something I’m missing around my foreach?

my foreach

```php
foreach($_POST['services'] as $value) {
$services_msg .="Services Desired: $value
";
}

```

Please help.

The $\_POST data must contain an array to use a foreach on it

You need to check if it’s blank using isset($\_POST[‘Services’]) before looping

Additionally - is this all the code? The stuff you posted?

You can’t use an else like that if so 😛

If no checkboxes are checked, the $\_POST[‘services’] array key will not be created. Just add a check to see if it exists first.

Yes. but I don’t want the error message if none of the boxes selected.

Put this at the beginning of your script:

```auto

error_reporting(0);

```

I prefer to turn off error reporting in my php.ini file. Google php.ini and you’ll find all kinds of stuff I’m sure…

Turning off error reporting is just hiding a problem - the problem is that your code isn’t 100% right and you are just hiding the warning messages. Granted, the messages are just warnings and the code doesn’t cause any real problems but it’s the principal that counts - you don’t learn proper syntax or coding methods by dodging the errors
