PHP - Guestbook Error
I have a guestbook that writes an entry to a text file, but when I first run it I get this error:
Warning: fread() [function.fread]: Length parameter must be greater than 0 in C:\xampp\htdocs\xampp\index.php on line 66 Is there a way I can get rid of that error and still be able to use my guestbook until I actual update my guestbook using a database? Similar TutorialsI am trying to modify Guestbook. In order to access the page, the user must log in using a screen name and email address that has been registered with the website. What I want to take the log in information and automatically populate the Name and email field of the input comment form. I have set up SESSION Variables (see below for the login php). <?php session_start(); require_once("dbcon.php"); $form = "<table> <form action='login.php' method='post'> <tr> <td>Username: </td><td><input type='text' name='user' size='20' /> </tr> <tr> <td>Email: </td><td><input type='text' name='emad' size='30' /> </tr> <tr> <td><input type='submit' name='submit' value='Login' /> <td><a href='New Contact.html'>New Account </a> </tr> </form> </table>"; // Do NOT use \" when you still have the option to use singlequotes, looks so messy... $user = $_POST['user']; $emad = $_POST['emad']; //defining these in the start makes the source looks nicer if(!$_POST['submit']) die($form); // just kill the rest of the script if the form isn't submitted. if(!$user || !$emad) die("Required fields missing<br /><br /> $form"); // killing the rest of the script and echoing the form and error $sql = "SELECT ident FROM Mix WHERE password = '$pass' AND username = '$user'"; // just like with the variables and prints/echoes, you don't need to ".$var." anything with double quotemarks $res = mysql_query($sql) or die(mysql_error()); if(mysql_num_rows($res) > 0) { $row = mysql_fetch_assoc($res); $_SESSION['uid'] = $row['id']; $_SESSION['un'] = $_POST['user']; //Setup user name into session variable. $_SESSION['ua'] = $_POST['emad']; //Setup email address into session variable. echo "You have been logged in as $user at $emad.

I am trying to populate teh Name and email fields but the SESSION variables don't show up.

I am doing a very basic guestbook. Having problems with the posting method. The code is below all I am doing is insert a record into a mysql table but when I post getting a blank page with no obvious errors! code is below. if ($_POST['submit']) { $name = $_POST['name']; $email = $_POST['email']; $message = $_POST['message']; $date = $_POST("Y-m-d"); $time = $_POST("H:i:s"); if($name&&$email&&$message) { $querypost = mysql_query("INSERT INTO guestbook (id, name, email, message, date, time) VALUES ('','$name','$email','$message','$date','$time')"); echo "Please wait.... <meta http-equiv='refresh' content='2'>"; } else echo "Please fill out all fields."; } Hello! I am trying to make a Guestbook with help from the internet. I have created all sites what i need, but i have some problems with the Input. For example here is the Name inputfrom the "sign.php" <form id="form1" name="form1" method="post" action="addguestbook.php"> <td> <table width="400" border="0" cellpadding="3" cellspacing="1" bgcolor="#FFFFFF"> <tr> <td width="117">Name</td> <td width="14">:</td> <td width="357"><input name="name" type="text" id="name" size="40" /></td> </tr> And here is the "insert sequence" from the "guestbook.php": $sql="INSERT INTO $tbl_name(name, email, comment, datetime) VALUES('$name', '$email', '$comment', '$datetime')"; $result=mysql_query($sql); If i open the guestbook.php i just can see the datetime. What went wrong? Thanks, Mark p.S.: sorry for my english. I've found an example of guestbook that I would like to use on my site, but when I tested it I got the following error: Warning: fread() [function.fread]: Length parameter must be greater than 0 in C:\xampp\htdocs\xampp\index.php on line 66 I've included the bits of code for addguestbook.php guestbook.txt(didnt not include) and index.php.

However I am having some errors, one being that when I submit a test message it still shows the "please enter your name and comments" thing I have set when people don't fill the required fields. The other error I'm having is if I put two test messages into the guestbook some of the info from the last message fills in the fields of the other one instead of what was actually filled into the form. For example, if I insert the name "Pat" and the comment "testing 1 2 3" into one message and than insert the name "Bob" and the comment "hi" for another message when I submit the second message it may instead of putting "hi" it'll put "testing 1 2 3" so I get: Posted by: Pat testing 1 2 3 ________________ Posted by: Bob testing 1 2 3 instead of: Posted by: Pat testing 1 2 3 ________________ Posted by: Bob hi Like it should....

I am working on updating an old guestbook with outdated code (predecated). I will follow the suggestions I have received here on this forum already by using the new MySQL PDO technique. I am pretty rusty on PHP and MySQL, since I haven't been using it for years. So it took me a while to get Xampp running and installing Virtual hosts, so I can test my code locally. This is all working now. I have decided to start from scratch, building my guestbook up gradually in order to be able to understand each step better. I am inspired by the following tutorial:
http://wiki.hashphp....ySQL_Developers
So far I have created four files
1. contribution_to_guestbook.html
2. put_in_guestbook.php
3. show_content_of_guestbook.php
4. mysql_functions.php
The guestbook is implemented as a table with the name guestbook in the MySQL database with the name my_database. The database contains six fields, which a id, time, ip, name, email and contribution. The user can write a contribution by filling in his name, email address and contribution in the form placed in the first file. These data for the fields name, email and contribution respectively are being sent to the second file. At the same time the datetime is automatically registered along with the IP address of the users computer in the fields time and ip. When inserted in the table in the database via the second file, the primary field id is automatically added and incremented by 1. After the insertion in the database, the user is directed to file 3, where the content of the whole guestbook is being displayed for the user to see. The 4th file is containing the connection details for the database, including the password.
NB! The IP address of the users computer is not being displayed but only collected in the case one want to block spammers from specific computers with fixed IP addresses. In order to better block for spam from computer bots, I will later place a question in the first file to only admit humans ...
My questions
Is the structure of my guestbook convenient? Would it be appropriate to create functions to make the code more readable and if so, how can I do it? I wanted to make a prepared statement in the 3. file in which I select the content on the guestbook in order to display it. Can it be done, and if so how do the code look like? I know I need more error handling. Also I need to test user input. For example if no contribution is being written, an error message should be shown to the user, etc. Do you have some suggestions here and how to do it? What about security? I hope the password for my database will not be accessible in any way? I will appreciate any comments on the four questions above and eventual something else I have overlooked! I hope my thread is not too long. Hope for some replies ... Here is my code so far (still just a framework!): 1. contribution_to_guestbook.html

I have a working guestbook, but adjusting the time is whats getting me. I am trying to get the time to change depending on the timezone. And I also trying to get the time in the format 1:00 PM, not 21:00. Then on a different note, how can I stop spamming and injections.

On clicking the submit a very quick screen splashes up with a load of writing out of whoch I could just read ...line function open data file... You can check it out at www.qualitycarersdirect.com/careasp/portal.asp then click on 'post on the baord' it is a php file. I have a simple guestbook set up. Even when I set the max post size to 6000000 (if you're wondering why Id allow that its cause I'm just using it as a private message board with one other person), after a certain amount of characters, it splits the post up into several messages and in place of the name of the poster, it's an IP. Any ideas why this is happening? Thanks. Hi I just implementet a PHP Guestbook in my Flash site, and it works almost perfectly. But i have one problem. Every time i try to write on the guestbook, and include a Colon : <---- , it wont work. How do i make it work? You can see the guestbook he http://www.meny-graphics.dk/blog by pressing "Mere" under the first entry, and scrolling down. The PHP file can be found he http://www.meny-graphics.dk/blog/GuestBook.php Thanks in advance! I have created a php guestbook for my site. The only problem I have with it is that when a user puts a carriage return in their entry, it is not replicated in the viewed post. I'm trying to figure out how I turn these returns into <br /> tags for display. Do I do something with the php that handles the input (i.e. somehow replace carriage returns with <br />'s) or is it to do with the output php code? Any pointers would be gratefully appreciated. This is the php for the guestbook entries output: Code: [Select] <?php include "connection.php"; $table = "guestbook"; $data = mysql_query("SELECT * FROM $table ORDER BY id DESC") or die(mysql_error()); echo "<div class='divide_message'>"; while($info = mysql_fetch_array( $data )) { $date = date("d/m/y",strtotime($info['date'])); echo "<div class='block message'>"; echo "<div class='message_name'>" . $info['name'] . ""; echo "<span class='date'>" . $date . "</span></div><br />"; echo "<div class='message_message'>" . $info['message'] . "</div>"; echo "</div>"; } echo "</div>"; ?> I am a new developer, trying to figure out what causing a memory error. The code goes through registered appointments and depends on the service ID, I have to free a 45 minutes for another service to be booked. Now, once I book an appointment for any of the services that can have 45 minutes free spot, the website takes forever to load the hours but doesn't show them, instead I get this error A PHP Error was encountered Severity: Error Message: Maximum execution time of 120 seconds exceeded

Appreciate if you folks could pls. help me understand (and more importantly resolve) this very weird error:
Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'ASC, purchase_later_flag ASC, shopper1_buy_flag AS' at line 3' in /var/www/index.php:67 Stack trace: #0 /var/www/index.php(67): PDO->query('SELECT shoplist...') #1 {main} thrown in /var/www/index.php on line 67
Everything seems to work fine when/if I use the following SQL query (which can also be seen commented out in my code towards the end of this post) :
$sql = "SELECT shoplist.*, store_master.store_name, item_master.item_name FROM shoplist, store_master, item_master WHERE shoplist.store_id = store_master.store_id AND shoplist.item_id = item_master.item_id";However, the moment I change my query to the following, which essentially just includes/adds the ORDER BY clause, I receive the error quoted above: $sql = "SELECT shoplist.*, store_master.store_name, item_master.item_name FROM shoplist, store_master, item_master ORDER BY purchased_flag ASC, purchase_later_flag ASC, shopper1_buy_flag ASC, shopper2_buy_flag ASC, store_name ASC) WHERE shoplist.store_id = store_master.store_id AND shoplist.item_id = item_master.item_id";In googling for this error I came across posts that suggested using "ORDER BY FIND_IN_SET()" and "ORDER BY FIELD()"...both of which I tried with no success. Here's the portion of my code which seems to have a problem, and line # 67 is the 3rd from bottom (third last) statement in the code below: <?php
/*
$sql = "SELECT shoplist.*, store_master.store_name, item_master.item_name

*/
$sql = "SELECT shoplist.*, store_master.store_name, item_master.item_name
FROM shoplist, store_master, item_master
ORDER BY FIND_IN_SET(purchased_flag ASC,
purchase_later_flag ASC,
shopper1_buy_flag ASC,
shopper2_buy_flag ASC,
store_name ASC)
WHERE shoplist.store_id = store_master.store_id
