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.

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.
Kod:
function clickable_link($text = '')
{
$text = preg_replace('#(script|about|applet|activex|chrome):#is', "\\1:", $text);
$ret = ' ' . $text;
$ret = preg_replace("#(^|[\n ])([\w]+?://[\w\#$%&~/.\-;:=,?@\[\]+]*)#is", "\\1<a href="\" target="\"_blank\"">\\2</a>", $ret);
$ret = preg_replace("#(^|[\n ])((www|ftp)\.[\w\#$%&~/.\-;:=,?@\[\]+]*)#is", "\\1<a href="\" target="\"_blank\"">\\2</a>", $ret);
$ret = preg_replace("#(^|[\n ])([a-z0-9&\-_.]+?)@([\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;
}
{
$text = preg_replace('#(script|about|applet|activex|chrome):#is', "\\1:", $text);
$ret = ' ' . $text;
$ret = preg_replace("#(^|[\n ])([\w]+?://[\w\#$%&~/.\-;:=,?@\[\]+]*)#is", "\\1<a href="\" target="\"_blank\"">\\2</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)));

Here is the comment box focus code below. When we click on a comment box text area.
Kod:
//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();
});
$('.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.
Kod:
// 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+"&post_id="+getpID, {
}, function(response){
$('#CommentPosted'+getpID).append($(response).fadeIn('slow'));
$("#commentMark-"+getpID).val();
});
}
});
$('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+"&post_id="+getpID, {
}, function(response){
$('#CommentPosted'+getpID).append($(response).fadeIn('slow'));
$("#commentMark-"+getpID).val();
});
}
});
Get more records code
Kod:
// 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?));
});
});
$(?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:
Kod:
//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();
});
}
});
});
$('a.c_delete').livequery("click", function(e){

return false;
