comment 1.0.0GNU Lesser Genera...4.0Databases, Content management


This class can be used to manage a generic comments system. It could be used to add comments to a blog, a guest book, etc..

The comments are stored in an SQL database table. The class can install the table and associated indexes. Currently it supports MySQL and Microsoft SQL server.

The class can add new comments, update an existing comment, generate HTML forms to submit a comment and show the comments summary.

It works fine with PHP versions 4 and greater.

The possibility to post comments about the content that is published in Web site pages is very interesting.

It helps attracting more users that are able to participate in the site communities in a relevant way, even if it is just by letting them express their opinions.

This package provides a generic solution that could be used to let the users post comments about articles, blog posts, reviews, in guest books, etc..

I want to query a database and add names to a guestbook


<head><title>Comment class example using mysql</title>


include '../includes/class_comment.php';

# ... connect here to your sql server
$sqlconnection = mysql_connect('myserver','myusername','mypassword');
if (!
$sqlconnection) { die('Could not connect: ' . mysql_error()); }

$sqltable = new sqltable( );
$sqltable->SQLTYPE = 'mysql';


# $id_for and $code_for are the arguments.
# $sqltable is the table from above
# the empty string is the path to the css directory
# NOTE: $code_for is never allowed to have more than 8 characters.

$comment = new comment(0,'example',$sqltable, '../' );
$comment->SQLTYPE = 'mysql';

# install() will create the "comments" sql table under normal conditions and mysql.
# it will fail normally under mssql. Just copy the text from the mssql_query() of
# the install() function into your SQL Query Analyzer if the following install() fails.
# And then execute it with administrators rights. Don't forget to give
# the correct privileges to the freshly created table "comments"

$comment->install(); // Preparing, checking for sql table "comments", writing cssfile if not existing



<h1>This is an example</h1>
This is some simple page which can be commented.
If the script is showing this text, then the comment class is properly installed.

And here may come some comments, which may be re-edited by the author as long
as the internet connection does not change.


<div align=center><div style="text-align:left;width:80%;margin:0 auto">


# some optional options:

# $comment->debug = false; //true; // show additional info if true

# maybe we put some finedivs around the comment parts? (package ...)
# $comment->before_insert = $roundinput2->gettop(); // for example only, the finediv class is not initiated in this script
# $comment->after_insert = $roundinput2->getbottom();
# $comment->before_comments = $finediv->gettop();
# $comment->after_comments = $finediv->getbottom();

# $comment->showcomments = true; // Show the comments from start, don't wait on a mouseclick.

# $comment->prevent_multiple = false; // true by default

# $comment->prevent_spam = false; // allow links? Is true by default and changes input to $say_nolinks if a link is found

# to use in other languages, you may like to change
# all the "say_xxxx" text strings here like so for German text:

  $comment->say_comment = 'Kommentar:<br><img src="images/writing2.gif" alt="Hand hält Feder">';
  $comment->say_comments = 'Kommentare';
  $comment->say_addcomment = 'Einen Kommentar hinzufügen';
  $comment->say_submit = 'Abschicken';
  $comment->say_nickname = 'Name/Alias:';
  $comment->say_update = 'Ändern';
  $comment->say_updated = 'Eintrag geändert.';
  $comment->say_close = 'Schließen (X)';
