VTS Posted April 28, 2006 Share Posted April 28, 2006 I have most of the program done for making a forum with php. The problem that I am running into is with a program that shows the posts in a topic. When I click on a topic, it displays a blank page. Any help would be greatly appreciated.here is the code from the prog that shows the posts in a topic:<?php/** * A script that shows the posts in a topic * * @version $Id$ * @copyright 2006 */// check for required info from the query stringif (!isset($_GET['topic_id'])) { header("Location: topiclist.php"); exit;}// connect to server and select database$conn = mysql_connect("localhost", "username", "password") or die(mysql_error());mysql_select_db("testDB", $conn) or die(mysql_error());// verify that the topic exists$verify_topic = "select topic_title from forum_topics where topic_id = $_GET[topic_id]";$verify_topic_res = mysql_query($verify_topic, $conn) or die(mysql_error());if (mysql_num_rows($verify_topic_res) < 1) { $display_block = "<p><em>You have selected an invalid topic. Please <a href=\"topiclist.php\">try again</a>.</em></p>";} else { // get topic title $topic_title = stripslashes(mysql_result($verify_topic_res, 0, 'topic_title')); // gather the posts $get_posts = "select post_id, topic_id, post_text, date_format(post_create_time, '%b %e %y at %r') as fmt_post_create_time, post_owner from `forum_posts` where topic_id = $_GET[topic_id] order by post_create_time asc"; $get_posts_res = mysql_query($get_posts, $conn) or die(mysql_error()); $sql = "SELECT topic_id, post_text FROM forum_posts WHERE topic_id = $_GET[topic_id]"; $result = mysql_query($sql, $conn) or die(mysql_error()); while ($array = mysql_fetch_array($result)) { echo "Text for the topic: " . $array['post_text'] . "<br />"; } // create the display string $display_block = " <p>Showing posts for the <strong>$topic_title</strong> topic:</p> <table width=100% cellpadding=3 cellspacing=1 border=1> <tr> <th>Author</th> <th>POST</th> </tr>"; while ($posts_info = mysql_fetch_array($get_posts_res)) { $post_id = $posts_info['post_id']; $post_text = n12br(stripslashes($posts_info['post_text'])); $post_create_time = $posts_info['fmt_post_create_time']; $post_owner = stripslashes($posts_info['post_owner']); // add to display $display_block .= " <tr> <td width=35% valign=top>$post_owner<br>$fmt_post_create_time</td> <td width=65% valign=top>$post_text<br><br> <a href=\"replytopost.php?post_id=$post_id;\"><strong>REPLY TO POST</strong></a></td> </tr>"; } // while // close up the table $display_block .= "</table>";} //end else?><html><head><title>Posts in Topic</title></head><body><h1>Posts in Topic</h1><?php print $display_block;?><p><a href="topiclist.php">Click Here</a> to go back to the main topic page</p></body></html> Link to comment https://forums.phpfreaks.com/topic/8668-problems-with-making-a-php-forum/ Share on other sites More sharing options...
alberto_zurita Posted April 29, 2006 Share Posted April 29, 2006 Hey VTS,It seems we have the same book. Good advise from Meloni isn't it? :)Now, one thing I had to do to get this code running was to change the:if (!isset($_GET['topic_id'])) {header("Location: topiclist.php");exit;}//for:if(!$topic_id){ header("Location: topic_list.php"); exit; }You see, the $_GET[] global array was not working, so I just used straight the $topic_id passed to this file from topiclist.php.If you entered already posts to the forum, you should be able to get them from the database. If it worked on mine, it should work on yours... ;)Well, let me know if you need more help Alberto Link to comment https://forums.phpfreaks.com/topic/8668-problems-with-making-a-php-forum/#findComment-31849 Share on other sites More sharing options...
VTS Posted May 1, 2006 Author Share Posted May 1, 2006 Well I changed the if statement but I still cant seem to get it to display anything....I have checked to make sure that all of the data is stored in the database and it is. So I guess I am still stumped. Link to comment https://forums.phpfreaks.com/topic/8668-problems-with-making-a-php-forum/#findComment-32474 Share on other sites More sharing options...
