PHP Mail Sending Blank Message On Page-Load - php

Question

I am having an issue with PHP Mailer. It is sending a blank email every time the page is loaded.
I'm sure it's something simple (maybe missing a condition if submit button is hit) to fix this.
Their documentation doesn't seem to have one though and the script first worked when I first used it but then started sending emails on page load after the first few times. Thanks!
<form method="post" action="">
<div class="form-group">
<input name="name" type="text" class="form-control" placeholder="Enter Name">
</div>
<div class="form-group">
<input name="email" type="email" class="form-control" placeholder="Enter Email">
</div>
<div class="form-group">
<input name="subject" type="text" class="form-control" placeholder="Enter Subject">
</div>
<div class="form-group">
<textarea name="message" class="form-control" rows="5" placeholder="Enter Message"></textarea>
</div>
<button name="submit" type="submit" value="submit" class="btn btn-submit">Submit</button>
</form>

Answer 1

You don't check to see if a form submission occurred. You just call your email code when the page loads. There are several ways to decide if a form submission occurred. One way is to check to see if the form action is POST:
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
// email code goes here
}
You can also check to see if the submit button was pressed:
if (isset($_POST['submit'])) {
// email code goes here
}
Other things to know:
You don't do any data validation so it is still possible for someone to submit nothing resulting in a blank email being sent
You don't protect against header injections which makes your form vulnerable to sending spam

Answer 2

This happen cause you didn't apply any condition for this to run so code runs line by line on page load .
so keep your mail sending code in submit check condition so it will run after submit click
if(isset($_POST['submit'])) {
// your mail sending code
}
or using any of your post data like for email check
if(!empty($_POST['email'])) {
// your mail sending code
}
