    Hello and thank you for your time,

    I want to restrict my users to be able to comment only once per post but be able to reply to comments freely. How can i do that?

    I found this code which disable the comment form if the user has comment, but it’s not working. The code it’s 3 years old.

    <?php
global $current_user;
$args = array('user_id' => $current_user->ID);
$usercomment = get_comments($args);
if(count($usercomment) >= 1){
 echo 'disabled';
} else {
 comment_form();
}
?>

    Thank you

    Hello,

    I think i can do it if i show in both cases the comment form but hide it conditionally in the places that i want based on css classes.
    but i have problem with my syntax if you can help.
    this is my code:

    <?php
global $current_user,$post;
$args = array('user_id' => $current_user->ID,'post_id' => $post->ID);
$usercomment = get_comments($args);
if(count($usercomment) >= 1){
 <nav class="commentifrated">
comment_form();
</nav>
} else {
<span class="commentifnotrated"> comment_form(); </span>;
 }
?>

    and i get this error
    Parse error: syntax error, unexpected ‘<‘ in

    Hi SialoS

    You cannot mix html and php. Try echoing the html

    <?php
global $current_user, $post;
$args = array( 'user_id' => $current_user->ID, 'post_id' => $post->ID );
$usercomment = get_comments( $args );
if ( count( $usercomment ) >= 1 ) {
	echo '<nav class="commentifrated">';
	comment_form();
	echo '</nav>';
} else {
	echo '<span class="commentifnotrated">' . comment_form() . '</span>';
}
?>

    Or use the alternative syntax:
    http://php.net/manual/en/control-structures.alternative-syntax.php

    <?php
global $current_user, $post;
$args = array( 'user_id' => $current_user->ID, 'post_id' => $post->ID );
$usercomment = get_comments( $args );
if ( count( $usercomment ) >= 1 ) : ?>
	<nav class="commentifrated">
		<?php comment_form(); ?>
	</nav>
<?php else : ?>
	<span class="commentifnotrated"><?php comment_form(); ?></span>;
<?php endif; ?>

    This is a solution with css trick .

    <?php
global $current_user,$post;
$args = array('user_id' => $current_user->ID,'post_id' => $post->ID);
$usercomment = get_comments($args);
if(count($usercomment) >= 1){?>
<div class="withcomment">
<?php
comment_form();
?>
</div>
<?php } else { ?>
<div class="withoutcomment">
<?php
comment_form();
?>
</div>
<?php }
?>

    and add this to your css

    .withcomment {
    display: none;
}

    if someone knows something better please post

    So after some time i done exactly what i wanted and i thought it would be nice to share.
    @keesiemeijer Thank you for your help. i have changed the code based on your contribution.

    So in Functions.php add

    function c_parent_comment_counter($pid,$uid){
    global $wpdb;
    $query = "SELECT COUNT(comment_post_id) AS count FROM $wpdb->comments WHERE <code>comment_approved</code> = 1 AND <code>comment_post_ID</code> = $pid AND <code>user_id</code> = $uid AND <code>comment_parent</code> = 0";
    $parents = $wpdb->get_row($query);
    return $parents->count;
}

    and in comments.php

    global $current_user, $post;
$number_of_parents = c_parent_comment_counter($post->ID,$current_user->ID);
echo "parents: ".$number_of_parents;
if ( $number_of_parents >= 1 ) {
	echo '<nav class="withcomment">';
	comment_form( array( 'title_reply' => __( 'Reply' ) ) );
	echo '</nav>';
} else {
	echo '<span class="withoutcomment">' . comment_form( array( 'title_reply' => __( 'Your opinion' ) ) ) . '</span>';
}
?>

    in style.css

    .withcomment {
	display: none;
}

    This will count how many parent comments a user added and if its one or more it will hide the form. if its 0 it will show the form. but when you click the reply button the form will show and you will be able to reply to any comment.
    THIS IS NOT HACK PROOF!!!
