hey guys, i been trying to figure out how to create a reply button for a messaging script written in php. it feels like i have been googling forever to try find an answer but with no results! does anyone know how to go about this? or do u know of any good tutorials on the subject? help would be massively appreciated! thanx
Which part of the reply button are you having trouble with? The submit to database part, how it would find the right thread to go to, or something else?
the whole thing lol when a user recieves a message, they have to navigate to compose.php and remember the users name in order to reply.
here is compose.php:
PHP Code:<?php
session_start();
$user = $_SESSION['username'];
include 'db.php';
//This checks to see if a user is logged in or not by seeing if the sessioned username varialble exists.
//You could change this check to however you want to validate your members, this is just how I did it.
if(!$user)
{
echo "<br><p>Blah blah you arent logged in and stuff, you should do that or something</p><br>";
}
else
{
//Query the database to see how many messages the logged in user has, then do a little math
//Find the percentage that your inbox is full (message count divided by 50)
//50 messages maximum, you can change that
$sql = mysql_query ("SELECT pm_count FROM users WHERE username='$user'");
$row = mysql_fetch_array ($sql);
$pm_count = $row['pm_count'];
//This is the math to figure out the percentage.
//The message could divided by 50 then multiplied by 100 so we dont have a number less than 1
$percent = $pm_count/'50';
$percent = $percent * '100';
?>
<br>
<center>
<b><p><a href="inbox.php">Inbox</a> | <a href="compose.php">Compose</a> | <a href="sent.php">Sentbox</a></b>
<b><p><?php echo "$pm_count"." of 50 Total | "."$percent"."% full"; ?></p></b>
</center>
<br>
<?php
//So here we get the variable submitted through the form to this page
$reciever = $_POST['username'];
$subject = $_POST['subject'];
$message = $_POST['message'];
$error = '0';
//If they are all blank we jsut say to compose a message
if(!$reciever AND !$subject AND !$message)
{
?>
<p><b>Please compose a message.</b></p>
<br>
<?php
}
//Since this form was partially filled out we need to return an error message
else
{
if (!$reciever)
{
$error = 'You must enter a reciever to your message';
}
if (!$subject)
{
$error = 'You must enter a subject';
}
if (!$message)
{
$error = 'You must enter a message';
}
//If the variable error is not set to zero, we have a problem and should show the error message
if($error != '0')
{
echo "<p>$error</p><br>";
}
//There are no errors so far which means the form is completely filled out
else
{
//Are the trying to send a message to a real user or to something they just made up?
$user_check = mysql_query("SELECT username FROM users WHERE username='$reciever'");
$user_check = mysql_num_rows($user_check);
//The user is real and not made up if this is true
if($user_check > '0')
{
//There might already be a sessioned time variable, if so we need to get it for the flood check
$time = $_SESSION['time'];
//If there is a time variable already, set it to the varialbe $old_time
if($time > '0')
{
$old_time = $time;
}
//Here we get the minutes and seconds on the server time using the date function, and set that to the $time variable
//Now we find the difference between this time ($time) and the time that the page was submitted ($old_time)
$time = date('is');
$difference = $time - $old_time;
$_SESSION['time'] = $time;
//If the two times have a difference greater or equal to 15, which is 15 seconds, they can submit the message, this is for flood protection
if($difference >= '15')
{
//Get their private message count
$sql = mysql_query ("SELECT pm_count FROM users WHERE username='$reciever'");
$row = mysql_fetch_array ($sql);
$pm_count = $row['pm_count'];
//You cant have more than 50 private messages, if they try sending a message to a user with a full inbox return an error message
if(pm_count == '50')
{
$error = 'The user you are trying to send a message to has 50 private messages, sorry but we cant send your message untill that user deletes some of their messages.';
}
else
{
//And now we stick the message in the database with all the correct information
mysql_query("INSERT INTO messages (reciever, sender, subject, message) VALUES('$reciever', '$user', '$subject', '$message')") or die (mysql_error());
//Add 1 to the pm count, update the reciever with the new pm count
$pm_count++;
mysql_query("UPDATE users SET pm_count='$pm_count' WHERE username='$reciever'");
}
//Let the user know everything went ok.
echo "<p><b>You have successfully sent a private message!</b></p><br>";
}
//Since they are trying to send messages faster than every 15 seconds, give them an error message
else
{
$error = 'You must wait 15 seconds before sending another private message';
}
}
//If they mis spelled or, made up a username, then give an error message telling them its wrong.
else
{
$error = 'That username does not exist, please try again. Remember to check your spelling, and don\'t make stuff up at random.';
}
}

So just do something like this:
Right? Or am I not getting something?Code:<a href="compose.php">Reply</a>
i was thinking about having the senders username pre-inserted into the reciever field so there is no need for user to look for the senders name
Yeah, try that.
do u know how i could do that?
Well, do something like this:
And then in compose.php the user would be that.Code:<a href="compose.php?user=$_GET['username_reply']">Reply</a>
i tried your method, but no joy. i also tried various tinkering, with no joy.
this is where im at now:
still dont seem to work, you have to select a user from a dropdown menu, do u think that might have something to do with it?PHP Code:<?php echo "<a href=\"compose.php?username=$sender\">Reply</a>"?>
it still loads the page and the url in status bar is '......compose.php?username=liamallan'
Well - once you do that, take the value of the "TO:" input, and do:
Code:value="<?php echo htmlentities($_GET['username']); ?>"
thanx mate, it worked like a charm!!
