msabas 0 Report post Posted July 19, 2006 I am very interested in learning how to create or start my own tutorial submitt site. What do I need to learn ? What do I need to have. Is there a script that can be made up or a software? What I would like to do is start my own tutorial submit site. something similar to good-tutorials and or pixel2life except those sites are really big and cover many tutoriasl for many different programs. Id like to just cover tutorials for maybe a total of 3 to 4 different programs. Im sure I need hosting a domain a site and some good forums to get something good going. But the main thing i need is the script on how to create this Tutorial Submit site What i found is this but im a bit confused since i do not know how to create the mysql tables portion Features include: Categories Comments Admin Panel First off, we gotta make some MySQL tables. First table: CREATE TABLE `tutorials` (`id` int(250) NOT NULL auto_increment,`submitter` varchar(250) NOT NULL,`text` text NOT NULL,`short_description` text NOT NULL,`title` varchar(250) NOT NULL,`cat_id` int(25) NOT NULL,`date_submitted` varchar(250) NOT NULL,`time_submitted` varchar(250) NOT NULL,`show_email` tinyint(1) NOT NULL,`email` varchar(250) NOT NULL,`views` int(250) NOT NULL default '0',`is_validated` tinyint(1) NOT NULL,PRIMARY KEY (`id`)) ENGINE=MyISAM; This sets up the table where all of the actual tutorials will be stored. Second table: CREATE TABLE `tutorials_categorys` (`id` int(25) NOT NULL auto_increment,`category` varchar(250) NOT NULL,`description` text NOT NULL,PRIMARY KEY (`id`)) ENGINE=MyISAM; This table will make the tutorial categorys, in which the different tutorials will be shown! Third table: CREATE TABLE `tutorials_comments` (`id` int(250) NOT NULL auto_increment,`tut_id` int(250) NOT NULL,`submitter` varchar(250) NOT NULL,`text` text NOT NULL,`time_submitted` varchar(250) NOT NULL,PRIMARY KEY (`id`)) ENGINE=MyISAM; This table will store all the tutorial comments in which we can later display them! Alrighty, now, onto the coding. First off, we are going to want to make a file called tutorials.php. We will be using switch() for our navigation system in this, and if you don't like it, replace it with your own. Here is the code: tutorials.php php code: <?php //------------------------------------------ //database connection mysql_connect("localhost", "username", "password") or die(mysql_error()); mysql_select_db("database") or die(mysql_error()); //end database connection //------------------------------------------ //------------------------------------------ //echo out a navigation panel echo " <center><a href='tutorials.php'>View Categorys</a> | <a href='tutorials.php?action=addtutorial'>Add Tutorial</a></center> ";

//now what we are doing here is looping through //the categorys table and getting all the //categorys and putting them into a select //so the user can select which category //the tutorial is on $query = mysql_query("SELECT * FROM tutorials_categorys ORDER BY id ASC") or die(mysql_error()); while($row = mysql_fetch_array($query)) { echo "<option value='$row[id]'>$row[category]"; } echo " </select> </td> </tr> <tr> <td>Tutorial:</td> <td><textarea name='tutorial' cols='40' rows='10'></textarea></td> </tr> </tr> <tr> <td>Short Description:</td> <td><textarea name='short_description' cols='40' rows='2'></textarea></td> </tr> <tr> <td>Email:</td> <td><input type='text' name='email' maxlength='50'></td> </tr> <tr> <td>Show Email?</td> <td><input type='checkbox' name='show_email' value='1' checked></td> </tr> <tr> <td colspan='2'><center><input type='submit' name='add_tutorial' value='Submit New Tutorial'></center></td> </tr> </form> </table> ";
