What is wrong with my contact from? - php

Question

On my website there is a contact form, for some reason after filling out the form, I won't get an email.
Below is the code for the form followed by the code for the sendmail.php code page. *For privacy I removed my email and replaced it with email#domain.com
Anyone know what could be wrong?
Thanks in advance,
Peter

Answer 1

Try changing if($_POST) to if( ! empty($_POST)). Also try var_dump($_POST); at the top of the page to make sure you're getting the variables through properly.

Answer 2

In my working contact form in php i use following verification:
if(isset($_POST['email']))
{
// your send mail code
}
BTW if you call directly:
mail("youremail#domain" , " your subject" , " mail body" , "From: example#example.com" );
your mail arives in inbox? i ask because you may not have acces to sendmail function from php.

Answer 3

1. Using
Your'e using PHP - Why you dont use functions that provides by PHP?
isEmail is nonsense, use filter_var to validate E-Mails:
if(filter_var($clientEmail, FILTER_VALIDATE_EMAIL)) {
// E-Mail is valid
}
2. POST Requests
To check if the post-request is taken, use isset or empty:
if(isset($_POST)) {
// Send the mail...
}
If you're using more than one form with an POST-Request on your side, be sure that you only handle the correct form. To prevent the problem, add an name attribute on your submit-button and check it:
if(isset($_POST['yourFirstButton'])) {
// Handle the first form
}
And
<input type="submit" name="yourFirstButton" value="Send" />
3. Use correct mail headers
Mail-Headers must be valid. A Propertie is Name: Value\r\n and NOT Name: Value.
You must add an \r\n at your last entry:
$headers = "From: " . $clientName . " <" . $clientEmail . ">" . "\r\n" . "Reply-To: " . $clientEmail . "\r\n";
4. Can your server send mails?
If you dont receive mails, check your server configuration or ask your server administrator. PHP must be configured to sending mails. Install sendmail for example. Otherwise fill out the SMPT settings in your PHP-Configuration (php.ini) to send a mail over an mailserver.
5. Using mail
Why you use the mail function? Mostly you (the programmer) must deal with headers and other to send a valid mail - Otherwise, the mailserver decline/bounce the mail or the mail goes to your spam folder.
If you're using mail, check the output:
$test = mail(/* Your parameters */);
var_dump($test);
If it's returned 1 or true, PHP says that the mail was probably sent.
Use an PHP Mailer class like PHPMailer (https://github.com/PHPMailer/PHPMailer)
