· #1 | | NamePros Regular Name: Lee Location: United Kingdom Join Date: Mar 2006 |  [PHP] Progress/Status Bar
I've just made this when i was messing about with GD functions in PHP, it is a progress bar type thing (not sure of the exact name). It takes 2 inputs, the total and used then creates a status bar type thing, could be useful for showing the amount of disk used.
Heres the main code:
ProgressBar.class.php PHP Code: <?php
/*
Class For creating a progress bar, using gd image library
Created by: Lee Findlow
Contact: leefindlow@gmail.com
Website: http://lee.conceptsublime.com/
*/
class ProgressBar{
//Variables to be used
var $Width = 200; //Width of the Bar
var $Height = 20; //Height of the bar
var $Total; //The total amount, i.e. upper limit
var $Highlight; //The amount to be lit
//Background color attributes
var $ColorBG_R = 255; //Red
var $ColorBG_G = 255; //Green
var $ColorBG_B = 255; //Blue
//Highlight Color Attributes
var $ColorHighlight_R = 0; //Red
var $ColorHighlight_G = 255; //Green
var $ColorHighlight_B = 0; //Blue
//Border Attributes
var $ColorBorder_R = 0; //Red
var $ColorBorder_G = 0; //Green
var $ColorBorder_B = 0; //Blue
//Function to create image
function Create(){
//Send out type header
header ('Content-type: image/png');
//Create Image
$img = imagecreatetruecolor($this->Width, $this->Height);
//Colors and Borders
//Background
$back = imagecolorallocate($img, $this->ColorBG_R, $this->ColorBG_G, $this->ColorBG_B);
imagefilledrectangle($img, 0, 0, $this->Width, $this->Height, $back);
//Filled Area
$Highlight = imagecolorallocate($img, $this->ColorHighlight_R, $this->ColorHighlight_G, $this->ColorHighlight_B);
//Calculate Length of lit area
$length = (($this->Width - 2)/$this->Total) * $this->Highlight;
//Create Full
imagefilledrectangle($img, 1, 0, $length, $this->Height, $Highlight);
//Lines around border
$line = imagecolorallocate($img, $this->ColorBorder_R, $this->ColorBorder_G, $this->ColorBorder_B);
imagerectangle($img, 0, 0, $this->Width - 1, $this->Height - 1, $line);
//Create Image
imagepng($img);
echo $img;
//Destroy temp image file
imagedestroy($img);
}
};
?>
It creates it in PNG format, which can be changed but i've been experimenting and PNG seemed to eb the smallest filesize, below are example usages of it:
Basic - will take the default values set in the script PHP Code: <?php
include_once('ProgressBar.class.php');
$ProgressBar = new ProgressBar;
$ProgressBar->Total = 1024;
$ProgressBar->Highlight = 137;
$ProgressBar->Create();
?>
Or a more advanced version, where you can set additional variables (not everything needs to be set) PHP Code: <?php
include_once('ProgressBar.class.php');
$ProgressBar = new ProgressBar;
$ProgressBar->Width = 300;
$ProgressBar->Height = 45;
$ProgressBar->Total = 1024;
$ProgressBar->Highlight = 137;
//Background of Bar (RGB)
$ProgressBar->ColorBG_R = 255;
$ProgressBar->ColorBG_G = 255;
$ProgressBar->ColorBG_B = 255;
//Highlighted portion
$ProgressBar->ColorHighlight_R = 0;
$ProgressBar->ColorHighlight_G = 205;
$ProgressBar->ColorHighlight_B = 0;
//Border
$ProgressBar->ColorBorder_R = 0;
$ProgressBar->ColorBorder_G = 0;
$ProgressBar->ColorBorder_B = 0;
$ProgressBar->Create();
?>
The only variables that need setting are total and highlight, any feedback appreciated
Thanks,
Lee

| The function imagecreatetrueimage() is not valid 
Maybe its just my GD acting up.
Anyways, you have to move the header() call to the line before the include("ProgressBar.class.php"); line | |

| Works fine for me.
The header call just needs to be before any actual output, to it's fine where it is. | |

Ah, I put some whitespace in the wrong place. That's why. | |

Just wondered if you've had any problems with it, it's the first time I''ve used GD and it [surprisingly] seems to be working

| Nice one, although you might want to look into just using an image and resizing it to a percentage of the table it's in.

· #9 | | NamePros Member | I hope you don't mind me posting this but I modified your code so I could just call it as an image file. I also changed some variable names to clear the code a little bit. PHP Code: <?php
/*
* ProgressBar.php by c0demonger
* Based on by ProgressBar.class.php by Lee Findlow / leefindlow@gmail.com
* ---------------------
* Sample Usage: <img src="ProgressBar.php?t=100&h=56" alt="56 Percent Full" />
*/
$Total = (int) $_GET['t'];
$Highlight = (int) $_GET['h'];
$Width = 200; //Width of the Bar
$Height = 20; //Height of the bar
//Background color attributes
$ColorBG_R = 255; //Red
$ColorBG_G = 255; //Green
$ColorBG_B = 255; //Blue
//Highlight Color Attributes
$ColorHighlight_R = 0; //Red
$ColorHighlight_G = 121; //Green
$ColorHighlight_B = 0; //Blue
//Border Color Attributes
$ColorBorder_R = 0; //Red
$ColorBorder_G = 0; //Green
$ColorBorder_B = 0; //Blue
//Send out type header
header ('Content-type: image/png');
//Create Image
$img = imagecreatetruecolor($Width, $Height);
//Colors and Borders
//Background
$color_back = imagecolorallocate($img, $ColorBG_R, $ColorBG_G, $ColorBG_B);
//Filled Area
$color_highlight = imagecolorallocate($img, $ColorHighlight_R, $ColorHighlight_G, $ColorHighlight_B);
//Border
$color_line = imagecolorallocate($img, $ColorBorder_R, $ColorBorder_G, $ColorBorder_B);
//Calculate Length of lit area
$length = (($Width - 2)/$Total) * $Highlight;
// draw background
imagefilledrectangle($img, 0, 0, $Width, $Height, $color_back);
// draw highlighted percentage
imagefilledrectangle($img, 1, 0, $length, $Height, $color_highlight);
// draw the border
imagerectangle($img, 0, 0, $Width - 1, $Height - 1, $color_line);
//Create Image
imagepng($img);
//Destroy temp image file
imagedestroy($img);
?>
Might come in handy for some one
Cheers. | |
