I've ran into this problem many times, and I'm sure others have too.

I'm trying to redirect users to the main page after login/doing other stuff on the website. But every time I login just to test it, I keep getting an error something about the header (can't remember the full error, haven't tested it in a while).

I'm using the PHP's way of redirecting:

header("Location:index.php");

I managed to find a work around, by outputting a link if they've logged in and when they click on the link, it takes them to the selected page. But I don't want that. I want it so it redirects automatically.

I do have error reporting on. Is there a way to get this working, without the error?

I can post my login code if needed.

You aren't really using hidden form fields to hold pricing information being sent to paypal, right?

It checks the price in my IPN script, but I also have the price in the button code too. Is there another way of holding the pricing information?

You haven't called the checkForm() function anywhere that I can see. Functions don't just run on their own.

Oops, my bad! I forgot to add 'onsubmit="return checkForm(this);"' to my form code. Thanks for that.

I have a small javascript function which is meant to check if a user has entered anything in the given textbox.

<script type="text/javascript">
 function checkForm(form) {
 if(form.on0.value == '') {
 alert("Error: No amount was entered!");
 form.on0.focus();
 return false;
 }
 return true;
 }
 </script>

		 <form action="https://www.paypal.com/cgi-bin/webscr" method="POST">
		 <input type="text" name="on0" value="" placeholder="Username">

That doesn't seem to work when I press my PayPal button.

		 </form>

Is there an easier way to check this?

December 13, 2012

There are several ways to approach this that would *work*; however, the one that makes the most sense is to have "Open" as the default value for the `status` column in the `unbanappeal` table. That way, any time an appeal is submitted, it is automatically an "open" ticket.

Then, once the issue/ticket has been closed (or whatever you do with it), you can then update the `status` to "Closed".

That is your best bet.

To address your current method, naturally all records would update based on your UPDATE query. You are not specifying a specific record. For future reference, use mysql_insert_id() (however, the method you are currently using is not recommended; use the method I posted already):
$query = mysql_query("INSERT INTO unbanappeal (username, email, topic, banned_you, ban_reason, unban_reason, ticket_id) VALUES ('$username','$email', '$topic','$banned','$banned_for','$why_unban','$ticket_id')") or die(mysql_error());
$insert_id = mysql_insert_id();

$set = mysql_query("UPDATE unbanappeal SET status = 'Open' WHERE `id` = ". $insert_id);
That is dependent on you having an ID column of sorts with AUTO INCREMENT.

Another method would be to add the "Open" value to the INSERT query:
$query = mysql_query("INSERT INTO unbanappeal (username, email, topic, banned_you, ban_reason, unban_reason, ticket_id, status) VALUES ('$username','$email', '$topic','$banned','$banned_for','$why_unban','$ticket_id','Open')") or die(mysql_error());
Again, use first method with default value for `status` column.

I never really thought about using the first method. But it's the method that I'm currently using now, thanks a lot

Basically, I have a form which my players fill in. Which then gets submitted to my database, and sets the question 'status' field to 'Open'. I have that working, but there's a problem.

When you submit a question, and my update query is executed, it sets every row in the database to 'Open' in the 'status' field. Is there a way to just set it to open for just that ticket?

Here is my code for inserting.

$query = mysql_query("INSERT INTO unbanappeal (username, email, topic, banned_you, ban_reason, unban_reason
   , ticket_id)
   VALUES ('$username','$email', '$topic','$banned','$banned_for','$why_unban','$ticket_id')") or die(mysql_error());

   $set = mysql_query("UPDATE unbanappeal SET status = 'Open'");

Also, is there a way to have SET in my $query. I've tried it, but it never worked.

December 6, 2012

Sorry for the late reply. And sorry for sounding like this... But what do you mean by 'add a static column to the select list'? I've done what you said, and to only use what columns I need, and have this so far.

SELECT 'ban' as type, time, player, banned_by, reason FROM bans
   WHERE player = '$search'
   union all
   SELECT 'kick' as type, time, player, kicked_by, reason FROM kicks
   WHERE player = '$search'

November 29, 2012

I've ran into a small problem. I have 2 tables called 'kicks' and 'bans', and I have created a query that selects all the data from both of them.

On my webpage, I have a table column called 'Type', and I'm wanting to display 'Ban' if it's from the ban table, and 'Kick' if it's from the kick table.

Is there a way to echo words out based on what database table the values are coming from?

Here's my query if needed.

$query = mysql_query("SELECT * FROM bans
 WHERE player = '$search'
 union all
 SELECT * FROM kicks
 WHERE player = '$search'");

Oh, that's no good then. Do you know if there is any alternative that will work in both Chrome and Firefox?

November 14, 2012

I have a dropdown menu which uses the onclick="window.location =''" feature to navigate to different pages on my statistics website, and it works fine in FireFox. But it doesn't seem to be working at all when I try it in Chrome....

Is there a simple way on how to get it working for both FireFox and Chrome, or doesn't Chrome support it?

Here's my dropdown if needed.

 <select>
	 <option></option>
	 <option onclick="window.location = 'http://www.stats.dawncraftmc.com/online.php'">Online</option>
	 <option onclick="window.location = 'http://www.stats.dawncraftmc.com/kills.php'">Kills</option>
	 <option onclick="window.location = 'http://www.stats.dawncraftmc.com/deaths.php'">Deaths</option>
	 <option onclick="window.location = 'http://www.stats.dawncraftmc.com/xp.php'">XP</option>
	 <option onclick="window.location = 'http://www.stats.dawncraftmc.com/blocks.php'">Blocks</option>
 </select>

November 13, 2012

You should definitely use a single query with a JOIN and a single loop.
SELECT players.id, players.username, players_killed.players_killed
FROM players JOIN players_killed ON players.id = players_killed.playerid
WHERE players_killed.players_killed > 100
LIMIT 50
You may want to through ORDER BY players_killed.players_killed DESC in there between the WHERE clause and the LIMIT clause.

Sorry for not selecting the columns that I actually needed. But after I changed the players_killed.players_kill to player_stats.players_killed it worked.

Thanks for your help

November 9, 2012

Thank you. Looks like I'll have to learn JOIN. I've put in the ORDER BY as you suggested, but now I have an error in my while loop.

$user = mysql_query("SELECT players.id, players.username, players_killed.players_killed
   FROM players JOIN players_killed ON players.id = players_killed.playerid
   WHERE players_killed.players_killed > 100
   ORDER BY players_killed.players_killed DESC
   LIMIT 50");

   while($stats = mysql_fetch_assoc($user)){

  echo "<tr bgcolor='#BFFFFF'><td>".$stats['username']."</td>";
   echo "<td bgcolor='#00FF00'>".$stats['players_killed']."</td></tr>";
   }

I get an error on line 90, which is

while($stats = mysql_fetch_assoc($user)){

mysql_fetch_assoc() expects parameter 1 to be resource

I've had the error before, and it was simple to fix. But I can't seem to find the problem this time...

November 8, 2012

Hi,

I'm trying to show the players that have more than 100 player kills. But I seem to be having a small problem.

I store my players username and statistics in different tables, and I can't seem to get it working. This is what I have so far:

$user = mysql_query("SELECT * FROM players LIMIT 50");
while($username = mysql_fetch_assoc($user)){

$id = $username['id'];
echo "<tr bgcolor='#BFFFFF'><td>".$username['username']."</td>";

$user_s = mysql_query("SELECT * FROM player_stats WHERE playerid = '$id' AND players_killed > 100");
while($player_stats = mysql_fetch_assoc($user_s)){

echo "<td bgcolor='#00FF00' class=\"td_b\">".$player_stats['players_killed']."</td></tr>";
}
}

It lists the first 50 players, which isn't what I want. I'm wanting it to display only kills over 100 from the player_stats where the id from players is equal to the player_id in player_stats.

I looked into joining the queries, but I wasn't sure if would of worked.

Could someone help me please?

Thanks in advance

October 30, 2012

The 'No results found' problem has been fixed. Thanks guys.

The code you've provided will return all records where the $search value is contained in the ticket_id field. The only reason I can see where all results would be returned is if $search is empty. Since you say that when you enter a value and there is a match that the appropriate records are displayed I assume that you are referencing the correct post value. If you are entering a value and there is no match - then no records would be displayed. So, I believe, either that is not the correct code that you've posted or the results you are getting are not exactly as you've stated them.

I need to check whether the user has entered their value in the input field next, as I'm doing 'No results found' as a default message if a user decides to go to that page in the URL. It does work now though, thanks for your reply.

October 30, 2012

Hi,

I'm having a small problem with my query. I'm basically getting the user's input, and searching the database for a match towards their input. If it finds a match, display it. If it doesn't, display a message.

My query does display the data if it finds a match, but it display everything from the database if it doesn't find anything.

Could someone tell me what I'm doing wrong please?

Here is my code:

<?php
$search = mysql_real_escape_string(trim($_POST['ticket']));

$query = mysql_query("SELECT * FROM unbanappeal WHERE ticket_id LIKE '%$search%'");
$ticket_id_check = mysql_num_rows($query);

if($ticket_id_check < 0){
echo "No results found.";
}else{
while($row = mysql_fetch_assoc($query)){
 echo $row['username'];
}
}
 ?>

Also, is it possible for me to change my query from displaying any data that's like the user's input, to the data that is exactly like the user's input?

Thanks in advance.

October 20, 2012

That works fantastic! Thank you

I never knew that it was so easy. Looks like I was just using the wrong input fields and passing it through to the IPN script wrong too

October 18, 2012

Thank you. I'm getting the custom field through now, it's sending as 'option_name1'.

I'm inserting the payment info into my database, I'm needing the custom field too. Since it's sending as 'option_name1', will I need to insert it as 'on0', or 'custom'?

Here's how I'm inserting it right now.

// add this order to a table of completed orders
    $payer_email = mysql_real_escape_string($_POST['payer_email']);
    $mc_gross = mysql_real_escape_string($_POST['mc_gross']);
    $on0 = mysql_real_escape_string($_POST['custom']);

    $sql = "INSERT INTO log VALUES
		    ('', '$txn_id', '$payer_email', '$mc_gross', '$on0')";

October 18, 2012

I just need it so the user can enter their username in the input field. I'm guessing it'll be custom, since you said the onX stuff is for multiple items?

Sorry about posting all of the code, people usually tend to get quite... nasty when you don't

October 18, 2012

Premiso, I got help from someone else on another forum. He told me to use 'on0' and 'os0', and that it should work after I put in

<?php
$on0 = $_POST['on0'];
?>
and:
<input type="hidden" name="on0" value="">
<input type="hidden" name="os0" value="<?php echo $on0; ?>">

which it never.

I don't want spoon feeding, but would you be able to tell me in some description how I'd go about setting the variable and passing it through to the IPN?

October 18, 2012

Sorry about that. It would of been better if it was posted at the bottom of the thread.

October 18, 2012

That's cool, do you have a question?

Could someone help me please? Tell me if i'm doing something wrong?

[/code]

Can you not read? There's my question.

October 18, 2012

Hi,

I'll try explain this the best I can.

I have a PayPal IPN script that works, inserts the the data into my database etc. But i'm having trouble with a custom variable. I can seem to pass it through to paypal.

I have my input field

<input type="text" name="on0" value="">

. This is where the will insert his/her username. And when the press the button

<form action="https://www.paypal.com/cgi-bin/webscr" method="POST">
		 <center><input type="text" name="on0" value="">
		 <br />
 <?php
 $on0 = $_POST['on0'];
 ?>

, it takes them to the PayPal page, they pay, and the variables passed through to the IPN goes into the database.
