Reloaded: Facebook Style Wall Posting and Comments System using jQuery PHP and Ajax.

Author ZeeShaN    Category AJAX, Facebook, JQuery, PHP, Web Development     Tags , , ,

Facebook style wall posting and commenting system. Try a new reloaded version of demo which is almost similar to facebook style.
My previous facebook style posting system was not so much like original facebook posting style and also there is no commenting system So I created this tutorial again to complete the commenting system and I tried my best to give my dear users a complete posting script with comments system. Facebook is now a days top social networking site. So I have created some tutorials similar to facebook. Youtube style rating is also very popular tutorial on this blog. Hope you like it.

Waiting for your feed back to make it more good.

Database Structure

CREATE TABLE `facebook_posts` (
  `p_id` int(11) NOT NULL auto_increment,
  `f_name` varchar(50) NOT NULL,
  `post` varchar(255) NOT NULL,
  `f_image` varchar(50) NOT NULL,
  `date_created` int(11) NOT NULL,
  `userip` varchar(200) NOT NULL,
  PRIMARY KEY  (`p_id`)
)
CREATE TABLE `facebook_posts_comments` (
  `c_id` int(11) NOT NULL auto_increment,
  `userip` varchar(200) NOT NULL,
  `comments` text NOT NULL,
  `date_created` int(11) NOT NULL,
  `post_id` int(11) NOT NULL,
   PRIMARY KEY  (`c_id`)
)

I have used ip check to make user restricted to there posts or comments. They can only there postings.
Two new function missed in source files. One for making links clickable and other for removing tags etc.

function clickable_link($text = '')
{
	$text = preg_replace('#(script|about|applet|activex|chrome):#is', "\\1:", $text);
	$ret = ' ' . $text;
	$ret = preg_replace("#(^|[\n ])([\w]+?://[\w\#$%&amp;~/.\-;:=,?@\[\]+]*)#is", "\\1<a href="\" target="\&quot;_blank\&quot;">\\2</a>", $ret);
 
	$ret = preg_replace("#(^|[\n ])((www|ftp)\.[\w\#$%&amp;~/.\-;:=,?@\[\]+]*)#is", "\\1<a href="\" target="\&quot;_blank\&quot;">\\2</a>", $ret);
	$ret = preg_replace("#(^|[\n ])([a-z0-9&amp;\-_.]+?)@([\w\-]+\.([\w\-\.]+\.)*[\w]+)#i", "\\1<a href="\">\\2@\\3</a>", $ret);
	$ret = substr($ret, 1);
	return $ret;
}
 
function checkValues($value = '')
{
	$value = trim($value);
	if (get_magic_quotes_gpc())
	{
		$value = stripslashes($value);
	}
 
	$value = strtr($value,array_flip(get_html_translation_table(HTML_ENTITIES)));
	$value = strip_tags($value);
	$value = mysql_real_escape_string($value);
	$value = htmlspecialchars($value);
 
	return $value;
}

Here is the comment box focus code below. When we click on a comment box text area.

//onfocus
$('.commentMark').livequery("focus", function(e){
 
	var parent  = $(this).parent();
	$(".commentBox").children(".commentMark").css('width','337px');
	$(".commentBox").children("a#SubmitComment").hide();
	$(".commentBox").children(".CommentImg").hide();			
 
	var getID =  parent.attr('id').replace('record-','');
	$("#commentBox-"+getID).children("a#SubmitComment").show();
	$('.commentMark').css('width','300px');
	$("#commentBox-"+getID).children(".CommentImg").show();
});

Submit comment code.

// I used livejquery plugin to work my code effective for dynamic elements.
$('a.comment').livequery("click", function(e){
 
	var getpID =  $(this).parent().attr('id').replace('commentBox-','');
	var comment_text = $("#commentMark-"+getpID).val();
 
	if(comment_text != "Write a comment...")
	{
		$.post("add_comment.php?comment_text="+comment_text+"&amp;post_id="+getpID, {
 
		}, function(response){
 
			$('#CommentPosted'+getpID).append($(response).fadeIn('slow'));
 
 
 
			$("#commentMark-"+getpID).val();
		});
	}
 
});

Get more records code

// I used livejquery plugin to work my code effective for dynamic elements.
$(‘a.more_records’).livequery(“click”, function(e){
 
var next = $(this).attr(‘id’).replace(‘more_’,”);
 
$.post(“posts.php?show_more_post=”+next, {
 
}, function(response){
$(‘#bottomMoreButton’).remove();
$(‘#posting’).append($(response).fadeIn(’slow’));

});
 
});

Delete comment code:

//deleteComment
$('a.c_delete').livequery("click", function(e){
 
	if(confirm('Are you sure you want to delete this comment?')==false)
	return false;
	e.preventDefault();
	var parent  = $(this).parent();
	var c_id =  $(this).attr('id').replace('CID-','');
	$.ajax({
		type: 'get',
		url: 'delete_comment.php?c_id='+ c_id,
		data: '',
		beforeSend: function(){
		},
		success: function(){
			parent.fadeOut(200,function(){
				parent.remove();
			});
		}
	});
});

          Hi Mohammad. Thanks, are you using new wall script code (http://facebook.99points.info) ? It is working script. You should check this one. There must be some div problems in your side may be some div iDs are not properly assigned. I can not solve like this, You should try this new version this is perfect and still did not hear any issue in it.

          Thanks

                There are some problem in your script. When I remove one post, all other post disappeared though they are not deleted. But, after refresh the come back. The same thing occurs for the comment deletion.
                when I left a comment there create problem in alignment of comment-box.
                How can I recover these problems.
                Plz, please, plz inform me how can I recover these problems.
                I think except these problems, your script is excellent.
