With a WordPress PHP template - I what doing an if statement to check if user is logged in, if he is then I want to show an email form and if he's not I want to ask users to login.
<?php if ( is_user_logged_in() ) {
<div role="tabpanel" class="tab-panel active" id="nomessage">
<div class="row">
<div class="col-lg-12">
<h4>You have to be logged in to send a message</h4>
</div>
</div>
</div>
} else {
<div class="tab-content">
<?php if($classieraToAuthor == 1){?>
<div role="tabpanel" class="tab-pane active" id="message">
<!--ShownMessage-->
<?php if(isset($_POST['submit']) && $_POST['submit'] == 'send_message'){?>
<div class="row">
<div class="col-lg-12">
<?php if($hasError == true){ ?>

<?php } ?>
<?php if($emailSent == true){ ?>
<div class="alert alert-success">
<?php echo $classieraContactThankyou; ?>
</div>
<?php } ?>
</div>
</div>
<?php } ?>
<!--ShownMessage-->
<form method="post" class="form-horizontal" data-toggle="validator" name="contactForm" action="<?php the_permalink(); ?>">
<div class="form-group">
<label class="col-sm-3 control-label" for="name"><?php esc_html_e('Name', 'classiera') ?> :</label>
<div class="col-sm-9">

<div class="form-group">
<div class="col-sm-9">

</div>
<div class="form-group">

<div class="col-sm-9">
<input id="humanTest" type="text" class="form-control form-control-xs" name="humanTest" placeholder="<?php esc_html_e('Your answer', 'classiera') ?>" required>
<input type="hidden" name="humanAnswer" id="humanAnswer" value="<?php echo $classieraNumberAnswer; ?>" />
<input type="hidden" name="classiera_post_title" id="classiera_post_title" value="<?php the_title(); ?>" />
<input type="hidden" name="classiera_post_url" id="classiera_post_url" value="<?php the_permalink(); ?>" />
</div>
</div><!--answer-->
<input type="hidden" name="submit" value="send_message" />
<button class="btn btn-primary btn-block btn-sm sharp btn-style-one" name="send_message" value="send_message" type="submit"><?php esc_html_e( 'Send Message', 'classiera' ); ?></button>
</form>
</div>
};
?>
First, I have added an if statement to check whether the user is logged in or not, if he is the first element is shown where is tells the user it has to be logged in to send a message. Then, if he is logged in a message form is shown instead.
Cannot get it to work, would appreciate all help a lot! Thanks in advance!

You couldn't mix PHP and HTML like this. You're missing to close PHP tag ?> before to write HTML.
EDIT As pointed by #mmm, your test is the inverse of what you want. You have to negate your test using the character !.
Try this :
<?php if ( ! is_user_logged_in() ) : ?>
<div role="tabpanel" class="tab-panel active" id="nomessage">
<div class="row">
<div class="col-lg-12">
<h4>You have to be logged in to send a message</h4>
</div>
</div>
</div>
<?php else: ?>
<!-- other HTML -->
<?php endif; ?>
Or :
<?php if ( is_user_logged_in() ) { ?>
<div role="tabpanel" class="tab-panel active" id="nomessage">
<div class="row">
<div class="col-lg-12">
<h4>You have to be logged in to send a message</h4>
</div>
</div>
</div>
<?php } else { ?>
<!-- other HTML -->
<?php } ?>
