PHP - Please Explain

I have some code that is supposed to get data from a site and then insert the gathered data into a database. The code does start adding data to database but it isn't adding data that it is getting from site that has starting data. What I mean is this. This code gets current player scores and such from gametracker and adds that to the database. then it will get player scores from my own tracker and add new scores to the ones that weere adde3d from game tracker. We did this so that our game servers continue tracking the scores for our new server trackers and not start out at zero initially. How ever when we run the code it says data was not written to database probably because server does not exists in database when in fact it really does. SO if someone could explain the code to me as to what it is doing then maybe I can figure out why it isn't working.

Code: [Select]
function InitializeServer( $sid, $ip, $name, &$totalplayers )
{
    !mysql_query( "DROP TABLE ".SERVER_TABLE_NAME.$sid.";" );    // we don't care if this fails if table didn't exist before
    if( !mysql_query( "CREATE TABLE ".SERVER_TABLE_NAME.$sid." ("
        ." `name` varchar(32), `score` int, `goal` int default 0, `leader` int default 0, `enemy` int default 0, `kia` int default 0, `roe` int default 0,"
        ." PRIMARY KEY(`name`) );" ) ) {
        die( "Error creating table: ".mysql_error() );
    }

    $id = 1;
    $page = 1;
    $done = FALSE;
    while( !$done ) {
        $data = http_request( "www.gametracker.com", "/server_info/".$ip."/top_players/?searchipp=50&searchpge=$page" );
        $pos = 0;
        $out = "";
        while( !$done ) {
            $num = GetStringInMiddle( $data, $pos, '<td class="c01">', '</td>' ); if( $num == NULL && $id > 1 ) break;
            if( $num != $id || $num == NULL ) { $done = TRUE; break; }
            $name = GetStringInMiddle( $data, $pos, '/">', '</a>' ); if( $name  === NULL ) break;
            $score = GetStringInMiddle( $data, $pos, '<td class="c04">', '</td>' );
            //$timePlayed  = GetStringInMiddle( $data, $pos, '<td class="c05">', '</td>' );
            //$scorePerMinute = GetStringInMiddle( $data, $pos, '<td class="c06">', '</td>' );
           
            if( $out != "" ) $out .= ",\n";
            $out .= "('$name', '$score')";
            $id ++;
            $totalplayers ++;
        }

        // Write data to database, if any               
        if( $out != "" )
        {
            $cmd = "INSERT INTO ".SERVER_TABLE_NAME.$sid." (`name`, `score`) VALUES ".$out.";";           
            if( !mysql_query( $cmd ) ) {
                echo "Error with insert: ".mysql_error()."\n[$cmd]";
            }
        }
        echo ($id-1)." "; flush(); ob_flush();
        $page++;
    }

    if( $id > 1 ) echo "\nInitalized server #$sid: ".$ip." - ".$name." - ".($id-1)." players added<br />";
    else echo "\nServer #$sid: ".$ip." - ".$name." - no players added (server probably not in database)<br />";

    flush(); ob_flush();
}

$sid, $ip and such are defined in other files that are included in the same file as this code is included in.

I am working with wordpress. I am coding some custom meta boxes following some code someone else had written. My code is working but I am not sure if I need to do it the way I am doing it. The person who wrote the code added the option like so

Code: [Select]
$custom = get_post_meta($post->ID);
$item_link = $custom["item_link"][0];

According to the wordpress codex, get_post_meta($post->ID) Returns a multidimensional array with all custom fields of a particular post or page.
so when I added a second option, I followed with this

Code: [Select]
$item_text = $custom["item_text"][0];
I guess my question would be..Do i need to add the index 0 to every option or should I increase it by 1 for every new option I add?

Can anyone explain to me why this isn't working , and explain how i would rectify the problem, Many Thanks.

Code: [Select]
<? $rawr = mysql_real_escape_string($_GET['type']); "SELECT COUNT(id) FROM items Where type = $rawr" ?>

function quote_smart($value, $handle) {

   if (get_magic_quotes_gpc()) {
       $value = stripslashes($value);
   }

   if (!is_numeric($value)) {
       $value = "'" . mysql_real_escape_string($value, $handle) . "'";
   }
   return $value;
}

how this script works and this script not linked to any variable or any other place so how this scripts works without linked or connected to anywhere
(sorry if this ques is dumb but i m newbie in php

Code: [Select]
if ($r['parent_id'] > 0)
            {
                $this->children[ $r['parent_id'] ][$r['id']] = $r;
            }
            else
            {
                $this->forums[ $r['id'] ] = $r;
            }
what is this code doing?

i don't get it how it uses the 2 variables in the " [ "  " ] " 's ? weird?

$r is a simple select * from a query..

i dont get the 2 variables with [] right next to each other?

I looked up 'how to get all POST variables' and I ended up putting this bit of code together.  Im not experienced at all with OOP programming, but I think that when '=>' is used its to do with OOP?  Anyway.  I dont get this code.  I understand Foreach $_POST, as $someVar, (BTW im looking for checkboxes from a form), However, If I leave out the '=> $val' I simply get a lot of 'on' values, indicating the checkboxes I checked.

However, WITH the '=> $val' I end up with the checkbox name.  Now i've changed the name of '$val' so i know its not a keyword.  But i dont get it.  Is there a way to access the value of the checkbox? Can someone explain to me whats going on here?  I know that I can get the value of the checkbox by $_POST['$checkRows'] But, I have a feeling It can be done in the foreach line.

foreach($_POST as $checkRows => $hip)
      {
         echo "POSTED: $checkRows<br>\n";         
      }

Please help!

[Edit: Sorry I found my answer by searching for "period", then finding out that it is a string operator, then read about that. Doesn't seem easy to search for ".=" in Google. Thanks]

I got some help here earlier, and I can pretty much understand everything, except I don't understand why there is Code: [Select]
$recordOptions .= "<option value=\"{$row['id']}\">";
        $recordOptions .= " {$row['firstname']} {$row['lastname']}, {$row['gender']}, {$row['dob']}";
        $recordOptions .= "</option>\n";
Why does this whole thing break without .= ? I am new to PHP so, sorry if the answer is really obvious.

Code: [Select]
$recordOptions = '';
$query = "SELECT * FROM people";
$result = mysql_query($query);
if(!$result)
{
    $recordOptions = "<option>Error Retrieving Records</option>\n";;
}
else
{
    while($row=mysql_fetch_assoc($result))
    {
        $recordOptions .= "<option value=\"{$row['id']}\">";
        $recordOptions .= " {$row['firstname']} {$row['lastname']}, {$row['gender']}, {$row['dob']}";
        $recordOptions .= "</option>\n";
    }
}

?>

Sorry this may sound insane.

Is there anyway to accomplish this,

using paypal you can creat buy it now buttons and whatnot. The problem with these is you set the price of the time when making the button.
Is there a way to set the price with php thus creating a dynamic price instead of a static one?

I know you can send paypal vars. but is there a way to edit the price?

Thanks I hope that makes sense at all

Hey guys,

this is what I'm trying to do.
I want to print on the member's profile page, a list of the products he has bought so far.

I've come with two solutions:

A) add a new field to the products' table, with the ID of every clients that bought that product;
B) add a new field to the members table, with the ID of every products he bought;

These are pretty similar approaches, but I've no idea on how can this be done.

It would look like:

Bought: 2, 3, 4, 5,

I dont know how to write this data or how to read it.

Any idea?
Thanks!

This should be an easy one but I'm looking for a bit of help.

I'm using a php framework and using includes to bring different pieces of a website togethor onto the page.
The top of the page uses a flash banner, then there are some simple text sections below.

The banner is in it's own php file as well.

Wondering if it's possible to have the banner NOT replay after each page load? I'm not sure if this is something I need to setup in the flash file, or if there is a way to do it in the php files?

Basically, the banner is the same for all of the pages, and I want it (once loaded) to stay on the page while the details on the bottom change, WITHOUT going through the entire animation again. Make sense?

here's the page as it stands now so you can get a better idea what I'm trying to do.

again not sure if this needs to be done in the flash side, or the php? Any ideas are better than what I've got!

Thanks in advance

Hi,

I have the following code


$w=$_GET['w'];
$h=isset($_GET['h'])?$_GET['h']:$w;
$x=isset($_GET['x'])?$_GET['x']:0;
$y=isset($_GET['y'])?$_GET['y']:0;
$filename=$_GET['src'];
header('Content-type: image/jpg');
header('Content-Disposition: attachment; filename='.$src);
$image = imagecreatefromjpeg($filename); 
$crop = imagecreatetruecolor($w,$h);
imagecopy ( $crop, $image, 0, 0, $x, $y, $w, $h );
imagejpeg($crop);


And display it as such
<img src="crop.php?x=<?php echo $_GET['x1']; ?>&y=<?php echo $_GET['y1']; ?>&w=300&h=300&src=cropper/castle.jpg">

So say the image is 500 x 333, it crops out a 300x300 section of it from X and Y. Works fine.
BUT, when i resize the image to say 450 x 300, it obviously still crops it from the 500 x 333 version so it looks different to what it should do.
I need a way to be able to resize the image in the above PHP and then imagecopy from that.

Cant think of how that would be done, any ideas?

Thank you!

Can someone help me understand parentheses structure?

Why here does the second empty() have no parentheses before it and an extra parentheses at the end?

if (empty($subject) && empty($text)) {
....

And here, why is there an extra parentheses at the end?

if (empty($subject) && (!empty($text))) {
...

And here, why double parentheses in the 1st empty() and none before the 2nd empty() ?

if ((!empty($subject)) && empty($text)) {
...

Thank You!

NEWBIE ALERT:
New to Programming
Newer to PHP
Bad at formulating coherent questions.....so here it goes....

Could someone explain
Code: [Select]
$fieldname = $_REQUEST['fieldname']
I understand "$_REQUEST An associative array that by default contains the contents of $_GET, $_POST and $_COOKIE"

I also understand you call the member of an array like so:  Code: [Select]
<?php
$arr = array("foo" => "bar", 12 => true);

echo $arr["foo"]; // bar
echo $arr[12];    // 1
?>
So I would expect that if someone wants to use something from the $_REQUEST Array they would use: Code: [Select]
$fieldname = $_REQUEST['$_GET']So I do not understand why "$fieldname" is inside the brackets.I suspect they might be setting this up to use $fieldname instead of $_REQUEST maybe...but why, that would be redundant? so I suspect I suspect wrong....
