function to allow the option of no text in comment textarea WordPress

Reigel Gallarde comments:

Currently, there's no way to add this ability using WordPress codes.

After investigating, I have a suggestion or solution.

First we'll have to remove the required attribute of the textarea. After that, when submitting, check if value of textarea is empty. If empty, change the value to '%dummy-text%'. Then change the '%dummy-text%' text on display.

something like this.

function rei_preprocess_comment($comment_data) {

if ($comment_data['comment_content'] == '%dummy-text%') {
$comment_data['comment_content'] = ''; // replace dummy text.
}

return $comment_data;
}
add_filter('preprocess_comment', 'rei_preprocess_comment');

function rei_wp_footer() {
?>
<script>
jQuery(function($){
var comment = $('textarea#comment');
comment.removeAttr('required'); // remove required attribute of textarea.
$('#commentform').on('submit',function(){
if (comment.val() == '') {
comment.css('text-indent','-999px').val('%dummy-text%'); // change to dummy text.
}
});

});
</script>
<?php
}
add_action( 'wp_footer', 'rei_wp_footer' );

I'm using a comment field plugin and only want that pulgin's comment field data outputted

<blockquote>what do you mean by "some hidden text" ?</blockquote>
I mean there could be the option to include a defined text that could satisfy the requirement to include text but then hide it so t can't be seen.
