Question

just wondering is there any way that I can return one value from my SQL database? Basically I am writining a website for my A level ICT coursework.
The website must allow posts to be made users and these posts must be stored in a table and then can be viewed by clicking on them
So far I have created a registration form and log in script to authenticate the session and delegate permission levels to users, I have created scripts which post threads to my database and have another script in place to store the data in the table
Now I wish to be able to view my posts when I click on them
So far my script is as follows

    <?php include_once('scripts/session_a.php') ; ?>
<?php include_once('scripts/connection.php') ; ?>


<?php


            $strSQL = "SELECT description FROM posts WHERE description=description";
            $result = mysql_query($strSQL) or die('SQL Error :: '.mysql_error());
            $row = mysql_fetch_assoc($result);

            echo $row['description'];


?>

and this script is called from

    <?php include_once('includes/header.php') ; ?>
    <?php include_once('includes/posts-header.php') ;?>

    <div> <!-- Main Wrapper -->
        <div class="Post Head"/><!-- Start Page -->
            <name="Post" id="Post"/>
            <h2>Absolute Beginners Forum</h2>




        <div name="postname" id="postname"/>    <!--PHP SCRIPT FEEDS NAME DATE AND AUTHOR HERE -->
                <label></label>

                <?php include('scripts/echo_test.php');?>

        </div>


        <div name="content" id="content"/>     <!-- PHP SCRIPT FEEDS CONTENT HERE -->

                <?php include('scripts/get_post_content.php')?>

        </div>

    </div><!-- End board-->







</div><!--End of page-->






</div> <!-- Main Wrapper Ends -->

a screenshot can be seen here of what I was trying to describe

Hopefully this generates a better understanding of my problem.

Thanks

Answer 1

instead of WHERE description=description you need to put something like WHERE id=$someid. this way you grab only the record matching a certain primary key id field. you would want to pass $someid to the page via a GET variable in the link most likely. you could also ad LIMIT 1 at the end to make sure the query only grabs one.
