전자 메일을 변경하기위한 드롭 다운 메뉴가있는 PHP 문의 양식

Question

나는 특정 의사에게 전자 메일 주소를 선택하기위한 드롭 다운 메뉴가있는 문의 양식을 작성 중입니다. 나는 템플릿에서 일하고 있으며 PHP에 대한 많은 경험이 없습니다. 폼에 서버를 업로드 할 때 경고 : array_key_exists()의 매개 변수 개수가 잘못되었습니다. 문제를 정확히 알 수 없습니다.

<?php 

// Set email variables 
$email_to = array('phys1' => 'phys1@xxxxxx.xxx', 'phys2' => 'phys2@xxxxxx.xxx');

$recipient = $emails[$_POST['dropdown']]; 
//send email to $recipient 
} 

$email_subject = 'Form submission'; 

// Set required fields 
$required_fields = array('fullname','email','comment'); 

// set error messages 
$error_messages = array(
'fullname' => 'Please enter a Name to proceed.', 
'email' => 'Please enter a valid Email Address to continue.', 
'comment' => 'Please enter your Message to continue.' 
); 

// Set form status 
$form_complete = FALSE; 

// configure validation array 
$validation = array(); 

// check form submittal 
if(!empty($_POST)) { 
// Sanitise POST array 
foreach($_POST as $key => $value) $_POST[$key] = remove_email_injection(trim($value)); 

// Loop into required fields and make sure they match our needs 
foreach($required_fields as $field) {  
    // the field has been submitted? 
    if(!array_key_exists($field, $_POST)) array_push($validation, $field); 

    // check there is information in the field? 
    if($_POST[$field] == '') array_push($validation, $field);

Answer 1

가 isset와 array_key_exists를 교체 시도하고 당신이 array_key_exists에 대한 설명서를 보면 당신은

if(isset($_POST['dropdown'])) 
{ 
    $recipient = $emails[$_POST['dropdown']]; 
    //send email to $recipient 
} 

Answer 2

, 당신은거야 작동하는지 확인 이 함수는 두 개의 매개 변수를 취합니다. 키 (배열 키)와 배열 (해당 배열 키/색인을 검색하려는 배열).

귀하의 코드 :

if(array_key_exists($_POST['dropdown'])) 

는 문제입니다. 당신은 아마도 의미 :

if(array_key_exists($_POST['dropdown'], $emails))
