    Hi, i have create a custom add shortcode for extract field from db table by select box.
    All work ok, but Now i don’t find a solution to validate this field.

    Any ideas?

    wpcf7_add_shortcode('postdropdown', 'createbox', true);
function createbox(){
global $wpdb;
$campocustom = $wpdb->get_results( "SELECT * FROM db_ippbrescia.wpipp_ai1ec_events WHERE contact_name IS NOT NULL AND contact_name != '';" );
$output = "<span class='wpcf7-form-control-wrap cursus'><select name='cursus' class='wpcf7-form-control wpcf7-select wpcf7-validates-as-required' aria-required='true' id='cursus' onchange='document.getElementById(\"cursus\").value=this.value;'><option>---</option><span>";
foreach ( $campocustom as $custom ) : setup_postdata($custom);
/**     echo $custom->contact_name; **/
        $title = ($custom->contact_name);
        $output .= "<option value='$title'> $title </option>";
endforeach;
$output .= "</select>";
return $output;
}

    i have added this code but not work

    add_filter( 'wpcf7_validate_postdropdown', 'your_validation_filter_func', 10, 2 );
add_filter( 'wpcf7_validate_postdropdown*', 'your_validation_filter_func', 10, 2 );

function your_validation_filter_func( $result, $tag ) {
	$type = $tag['type'];
	$name = $tag['name'];

	if ( 'postdropdown' == $name ) {
		$the_value = $_POST[$name];

		if ( is_not_valid_against_your_validation( $the_value ) ) {
			$result['valid'] = false;
			$result['reason'][$name] = "Error message here";
		}
	}

	return $result;
}

    $output = "<span class='wpcf7-form-control-wrap cursus'><select name='cursus' class='wpcf7-form-control wpcf7-select wpcf7-validates-as-required' aria-required='true' id='cursus' onchange='document.getElementById(\"cursus\").value=this.value;'><option>---</option><span>";

    Because the name of the select box is “cursus”, not “postdropdown”.

    if ( 'postdropdown' == $name ) {
		$the_value = $_POST[$name];

    Hi Miyoshi, i have tried to change code to “cursus”, but when i try to send form I get a loop and the email is not sent ??

    if ( 'cursus' == $name ) {
		$the_value = $_POST[$name];

    I have set my php.ini in debug mode but i don’t see any errors ??

    this is apache log:

    [Sat Jan 10 09:39:42 2015] [error] [client 192.168.20.40] PHP Fatal error: Call to undefined function is_not_valid_against_your_validation()

    this is my error

    So in what cases an user input “is not valid against your validation”? It’s up to you.

    “is not valid against your validation” when default value of custom select form is “—“.
    VIEW

    I can’t write a correct function ??

    sorry but $output should be:

    $output = "<span class='wpcf7-form-control-wrap cursus'><select name='cursus' class='wpcf7-form-control wpcf7-select wpcf7-validates-as-required' aria-required='true' id='cursus' onchange='document.getElementById(\"cursus\").value=this.value;'><option>---</option><span>";

    or

    $output = "<span class='is not valid against your validation cursus'><select name='cursus' class='wpcf7-form-control wpcf7-select wpcf7-validates-as-required' aria-required='true' id='cursus' onchange='document.getElementById(\"cursus\").value=this.value;'><option>---</option><span>";

    Hi, i have resolved the problem, the validation function now is:

    function filter_cursusecm($result,$tag){
        $type = $tag['type'];
        $name = $tag['name'];
        if($name == 'cursusecm'){
                $the_value = $_POST[$name];
                if(!is_cursusecm_blank($the_value)){
                        $result['valid'] = false;
                        $result['reason'][$name] = '<br>---------------------------------------------------------------------------------------------<br>Attenzione! Non hai indicato il Corso al quale ti vuoi iscrivere. Grazie<br>---------------------------------------------------------------------------------------------';
                }
        }
        return $result;
}
