Sum validation

    Hi there!

    I’m trying to insert an error message whether the sum of some input fields is greater than a certain number.

    More specifically, the contact form is to enquire about the vacancy of hotel room.
    For each room, I need to know how many people/pets are going to be in that room.
    Of course, there is a limit to it, and that is 4 people/pets.

    I’d like to insert an error message anytime they try to book a room for more than 4 people/pets.

    In the contact form, it would be something like:

    <label> Adults*
[select* r1-adults "1" "2" "3" "4"] </label>
<label> Children*
[select* r1-children "0" "1" "2" "3"] </label>
<label> Babies*
[select* r1-babies "0" "1" "2" "3"] </label>
<label> Pets*
[select* r1-pets "0" "1" "2" "3"] </label>

    In the functions.php:

    add_filter( 'wpcf7_max_capacity*', 'custom_max_capacity_validation_filter', 20, 2 );

function custom_max_capacity_validation_filter( $result, $tag, $adults, $children, $babies, $pets ) {
	$tag = new WPCF7_FormTag( $tag );
	$adults=$_POST['r1-adults'];
	$children=$_POST['r1-children'];
	$babies=$_POST['r1-babies'];
	$pets=$_POST['r1-pets'];
	$sum=( $adults+$children+$babies+$pets);
	return $sum;
	if ($sum > "4" ) {
		$result->invalidate( $tag, "Rooms cannot accomodate more than 4 people/pets" );
	}
	return $result;
}

    It does not work, and I cannot find a way to solve the syntax.
    Can you help me, please? I would really appreciate it!

    Hi Takayuki,

    thanks for you reply. I did get the idea from that code, but I could not make it works…
    My last attempt was:

    add_filter( 'wpcf7_max_capacity*', 'custom_max_capacity_validation_filter', 20, 2 );

function custom_max_capacity_validation_filter( $result, $tag, $zero, $adults, $children, $babies, $pets ) {
	$tag = new WPCF7_FormTag( $tag );
	$zero = "0";
	if ( 'r1-adults' == $tag->name AND 'r1-children' == $tag->name AND 'r1-babies' == $tag->name AND 'r1-pets' == $tag->name ) {
	$adults = isset( $_POST['r1-adults'] ) ? settype(trim( $_POST['r1-adults'] ), "integer") : settype($zero, "integer");
	$children = isset( $_POST['r1-children'] ) ? settype(trim( $_POST['r1-children'] ), "integer") : settype($zero, "integer");
	$babies = isset( $_POST['r1-babies'] ) ? settype(trim( $_POST['r1-babies'] ), "integer") : settype($zero, "integer");
	$pets = isset( $_POST['r1-pets'] ) ? settype(trim( $_POST['r1-pets'] ), "integer") : settype($zero, "integer");	
	$sum=$adults+$children+$babies+$pets;
		if ($sum > 4 ) {
			$result->invalidate( $tag, "greater than 4" );
		}
	}
	return $result;
}

    I think the problem is in the condition:
    if ( ‘r1-adults’ == $tag->name AND ‘r1-children’ == $tag->name AND ‘r1-babies’ == $tag->name AND ‘r1-pets’ == $tag->name ) {

    which in your Custom Validation, would correspond to:
    if ( ‘your-email-confirm’ == $tag->name ) {

    but I do not know how to define it…

    Any further suggestion?

    In contact-form-7/includes/functions.php:

    add_filter( 'wpcf7_validate_text', 'custom_ROOM1SUM_validation_filter', 20, 2 );
 
function custom_ROOM1SUM_validation_filter( $result, $tag ) {
	$tag = new WPCF7_Shortcode( $tag );
	$zero = "0";
 
    if ( 'R1-SUM' == $tag->name ) {
        $adults = isset( $_POST['r1-adults'] ) ? $_POST['r1-adults'] : $zero;
	settype( $adults, "integer");
	$children = isset( $_POST['r1-children'] ) ? $_POST['r1-children'] : $zero;
	settype( $children, "integer");
	$babies = isset( $_POST['r1-babies'] ) ? $_POST['r1-babies'] : $zero;
	settype( $babies, "integer");
	$pets = isset( $_POST['r1-pets'] ) ? $_POST['r1-pets'] : $zero;
	settype( $pets, "integer");
 
        if ( ($adults+$children+$babies+$pets) > 4) {
            $result->invalidate( $tag, "No more than 4 occupants per room." );
        }
    }
    return $result;
}

    In CSS:

    #zero_height {
	border: 0;
	height: 0;
	line-height: 0;
	padding: 0;
}

    In the contact form:

    <label> Adults*
[select* r1-adults include_blank "1" "2" "3" "4"] </label>

<label> Children (4-12 years)
[select* r1-children "0" "1" "2" "3"] </label>

<label>  Babies (0-3 years)
[select* r1-babies "0" "1" "2" "3"] </label>

<label> Small and medium sized pets
[select* r1-pets "0" "1" "2" "3"] </label>
[text R1-SUM id:zero_height]

    Hello,

    Thanks for the code. How do I modify it so that the dropdown has descriptions and values?

    Example of a dropdown I’m trying to create:

    Q: Are you older that 21?
    A: Yes – would have a value of 10 and No would be zero.

    In the function I would process the number and not the “Yes” or “No”.

    Thanks!
