Hi Faris ,
1- You can override the item_comments_form.php template file, to hide the site/url field just comment its html, by <!-- -->
Like this:
<!--<label class="formUrl" for="commentURL"><?php echo JText::_('K2_WEBSITE_URL'); ?></label>
<input class="inputbox" type="text" name="commentURL" id="commentURL" value="<?php echo JText::_('K2_ENTER_YOUR_SITE_URL'); ?>" onblur="if(this.value=='') this.value='<?php echo JText::_('K2_ENTER_YOUR_SITE_URL'); ?>';" onfocus="if(this.value=='<?php echo JText::_('K2_ENTER_YOUR_SITE_URL'); ?>') this.value='';" />-->
2- You can change leave comment to leave review, using language overrides. to access it, go to backend: Extensions->Languages->Overrides.
Create a new override, enter "
K2_LEAVE_A_COMMENT" in the
Language Constant field and "
Leave a review" in the
Text field, then save.
