Many thanks for your hard work ~Z~ Man. I tried the new coding but it did not work for me. Perhaps due to a caching issue... I'm using cloudflare for my site now. So, there are no deletions? Just your additions to the code?

a pure <enter> is enclosing each newline into divs.

Maaaan, I spent at least 2 hour playing with that line. All I was getting is div's. Had no idea why they were showing up. I see now.

Ok, so changing false to true lets you use enter for successive lines but doesn't put any spacing between them. How do you recode the js to put a break <br>or new line after each line of text?

Well, finally I had a little time to have a closer look ....
In opposite to <shift><enter> which is inserting a <br> into the text
a pure <enter> is enclosing each newline into divs.
That is, a text with 2 newlines will be encoded like

Line1
<div>Line2</div>
<div>Line3</div>

and since the current replacement code isn't prepared to handle a construct like that, all divs are simply removed - and Line1Line2Line3 will be submitted and saved. ;)

So far for the explanation why a simple change from false to true can't work.

Thus, to get things working as requested, we need to take extra care about the divs like

$text = $replace_tags($text, '<div>').replace(/\<div\\?>/g, "<br>");
$text = $replace_tags($text, '<br>').replace(/\<\/div\\?>/g, "<br>");

and insert these 2 lines before the old and final <br> to newline replacement

$text = $replace_tags($text, '<br>').replace(/\<br\\?>/g, '\n');

in order to achieve a reversed logic:
a simple <enter> gives a newline and <shift><enter> will save the comment

Allon Prooit, Naser Naser I have asked this question on stackoverflow a minute ago. Chances anyone would answer is about 1%. But who knows.

@MadRomas
Thank you

Allon Prooit that, I have no idea, as im not a JS expert. Its a question for developers or stackoverflow.

Ok, so changing false to true lets you use enter for successive lines but doesn't put any spacing between them. How do you recode the js to put a break <br>or new line \n after each line of text?

@MadRomas
Thanks for your help I wanted is how to send a comment by button

The thing is, to true(2 places). js/OssnComments.php

if (e.shiftKey === false)

SOPOSE TO do what you wanted to accomplish.

Assuming we added the button

<input type="submit" class="btn btn-comment" value="<?php echo ossn_print('comment'); ?>"/>

How will the process be done?
