Sql and PHP+GD

Recommended Posts

I want to create a script that creates an image on the fly based on one $HTTP_GET_VARS and two or three sql commands

this is the base for what i want but instead of using the http_get_vars function i want to call the data from a database the only HTTP_GET_VARS i want is a 'user'
[code]<?php

$item = $HTTP_GET_VARS['item'];
$have = $HTTP_GET_VARS['have'];
$need = $HTTP_GET_VARS['need'];
$height = 40;
$width = 116;
$fontsize = 6;
$frac = $have/$need;
$pct = 100 * $frac;

$img = imagecreate($width,$height);
$red = imagecolorallocate($img,255,0,0);
$black = imagecolorallocate($img,0,0,0);
$white = imagecolorallocate($img,255,255,255);
$bg = imageCreateFromPNG ('bg.png');
$bar =imageCreateFromPNG ('fill.png');
imageSetTile ($img, $bg);
imageFilledRectangle ($img, 0, 0, 116, 40, IMG_COLOR_TILED);
imageSetTile ($img, $bar);
ImageFilledRectangle($img, 7, 22, (114 * $frac), 34, IMG_COLOR_TILED);

$font = '04B_09__.ttf';
$text1 = "Questing For";
$text2 = $item;
$text3 = $have . "/" . $need;
$textwidth1 = floor(imagefontwidth($font) * strlen($text1));
$textleft1 = (($width - $textwidth1) / 2) + 12;
$textwidth2 = floor(imagefontwidth($font) * strlen($text2));
$textleft2 = (($width - $textwidth2) / 2) + 12;
imagettftext($img, $fontsize, 0, $textleft1, 8, $white, $font, $text1);
imagettftext($img, $fontsize, 0, $textleft2, 19, $white, $font, $text2);
imagettftext($img, 6, 0, 46, 32, $black, $font, $text3);

header('content-type: image/png');
imagepng($img);
   
?>[/code]

[code=php:0]
<?php

//used to find which user to query for in the database
$user = mysql_real_escape_string(trim($HTTP_GET_VARS['user']));

// Query
$sql = "SELECT item, have, need FROM your_db_table WHERE user = '$user'";

// Run Query
$result = mysql_query($sql) or die("Error retrieving user info: ".mysql_error());

// Grab the user results
while( $row = mysql_fetch_array($result) ){
  $item = $row['item'];
  $have = $row['have'];
  $need = $row['need'];
}

// You can get rid of these
//change these to get the value from the results of the query
//$item = $HTTP_GET_VARS['item'];
//$have = $HTTP_GET_VARS['have'];
//$need = $HTTP_GET_VARS['need'];
?>
