PHP - Help With Dynamic Library

Hi everyone.

There are two nice script which are advanced for me to understand. There is a  Knockout tournament scheduler class that makes image of the bracket. and there is a code that makes html of the bracket with jquery. I want to use the class with jquery. but I don't know how to do that and where to start. the class below needs to implement to this http://whileonefork.blogspot.com/2010/10/jquery-json-to-draw-elimination-single.html

I attached the php script. please help me!

hi,

i'm using the fpdf library to generate PDF's from form input. It all worked well on my local host, but now that i have transferred to a web server it displays the following error when trying to generate a PDF.


Warning: require(/fpdf16/fpdf.php) [function.require]: failed to open stream: No such file or directory in /home/ddgq0o2n/public_html/quote_builder/pdf.php on line 2

Fatal error: require() [function.require]: Failed opening required '/fpdf16/fpdf.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/ddgq0o2n/public_html/quote_builder/pdf.php on line 2


i have searched for "include_path", but can't find it anywhere.

i'm thinking it's a server problem, where the library may not be compatible or something needs to be switched on, as it worked fine on my local host.


any help and suggestions welcome


thanks.

I am trying to create a basic image with GD library, but my browser says that the image cannot be displayed because it contains errors... I have no idea why.  Here's my code:

Code: [Select]
switch($_GET['case']){

case "progressbar":

header('Content-Type: image/jpeg');

$barWidth = 6;
$barHeight = 14;
$barPadding = 2;

$imageWidth = ($barWidth * 10) + (10 * $barPadding);

$imageHeight = ($barHeight + ($barPadding * 2));

$img = @imagecreate($imageWidth, $imageHeight);
$imgBorder = imagecolorallocate($img, 0, 0, 0);

//imagefilledrectangle($img, 1, $imageHeight -1, $imageWidth - 1, $imageHeight - 1, $imgBorder);
$output = "Hello, world!";

imagestring($img, 1, 4, 4, $output, $imgBorder);
imagejpeg($img);
imagedestroy($img);

break;

}
I have a file called image.php that i use to create images and I use the URL image.php?case=progressbar.

Hey Guys

Ok I can postion text using the GD library using the following:

Code: [Select]
imagefttext($rImg, 13, 0, 105, 55, $black, $font_file,$Username);
How would do the same using an image?  For example

Code: [Select]
whateverfunction($rImg, 13, 0, 105, 55,$ImagePath);
Thanks a million.

 
Hey guys, I have created combined images from edits I had laying around.  I have a chair, and i'm trying to combine different colored tops with a pair of legs using a radio button to choose the top color.  Here is what I have so far for the form page:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Untitled Document</title>
</head>

<body>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
<label>Seat Color Choices:</label><br>
Red<input type="radio" name="color" value="red" id="red" onFocus="getElementById('config').src = 'red.php'" >
Orange<input type="radio" name="color" value="orange" id="orange" onFocus="getElementById('config').src = 'orange.php'" >
Ivory<input type="radio" name="color" value="ivory" id="ivory" onFocus="getElementById('config').src = 'ivory.php'" >
Black<input type="radio" name="color" value="black" id="black" onFocus="getElementById('config').src = 'black.php'" >
</form>

<img src="black.php" id="config" alt="color choice for lola chair">

</body>
</html>

...and here is one of my image files for an example:
<?php
//Report any errors
ini_set ("display_errors", "1");
error_reporting(E_ALL);
 
//Set the correct content type 
header('content-type: image/jpeg');

 
$base = imagecreatefromjpeg('lola_base.jpg');
$red = imagecreatefromgif('lola_red.gif');
$orange = imagecreatefromgif('lola_orange.gif');
$ivory = imagecreatefromgif('lola_ivory.gif');
$black = imagecreatefromgif('lola_black.gif');


imagecopy($base, $red, 0 , 0 , 0, 0,250, 250);

imagejpeg($base); 
//Clear up memory used

imagedestroy($base);

?>

The problem is, I need to be able to dynamically change which images are being combined.  I can't have a different file for each combo (ex. red.gif, black.gif, ivory.gif, etc.) I need it to create them on cue from a single file/function. Is there a way to do that with PHP GD library?

Thats my question. Its a good practice? Gives error in a php file without html, for example?

About the library, i have a 1500lines single php file and i modualritizing it. There is any advice in general when creating a php library?

Hello everyone,

What is the best way to take HTML formatted text and overlay it on a image (presumably using php's GD functions)? Unfortunately, HTML tags are ignored and any kind of code is treated as plaintext by imagefttext(). However, I need this HTML DIV box pasted onto an image and I intend to get it done.

To make things slightly worst, this is a dynamic, PHP generated DIV box. I had an idea of utilizing some kind of buffering to generate my DIV box, convert that DIV box to an image and finally paste it onto my image using the GD library. If that sounds like a reasonable idea, can someone please help me get started?

Thanks in advance, guys!

Suppose you have a ENORMOUS library class where you have collected - perhaps - validation functions.

Suppose you also have a small php script that you wish to use one of these validation functions in.

So, you include the class.

Is there a lot of "overhead" involved in including a huge class of which you use only one function?

Font size GD Library

Hi All

I'm trying to create a font tester - http://www.ttmt.org.uk/fonts/index.php (this demo doesn't use the font I'm using.). I'm using the GD library to create images of the text. I'm not happy with the quality of the fonts at small sizes. I've tried everything to fix it but nothing is working. One suggestion I had was to create the fonts larger then reduce the size of the image.

Can anyone offer any advise how I might do this?


Code: [Select]
<?php
        
header('Content-Type: image/png');

$im = imagecreatetruecolor(1000, 200);

$gray = imagecolorallocate($im, 240, 240, 240);
$black = imagecolorallocate($im, 0, 0, 0);
imagefilledrectangle($im, 0, 0, 1000, 199, $gray);
    
  $text = $_GET['text'];
$textSize = $_GET['size'];
$font = $_GET['font'];
  
  imagefttext($im, $textSize, 0, 15, 160, $black, $font, $text);

imagepng($im);

imagedestroy($im);

How to implement the library

I don't know how to implement  orientation of the image when the image is submitted

I want to automatically change the orientation of the image.

here's the links I tried:

http://image.intervention.io/getting_started/installation https://artisansweb.net/resize-image-php-using-intervention-image-library/ https://medium.com/thetiltblog/fixing-rotated-mobile-image-uploads-in-php-803bb96a852c https://www.youtube.com/watch?v=XSO4f3OeeZE https://www.youtube.com/watch?v=HjHSgGFqAtE

here's my code
 

<?php

	include("../incs/config.php");

	$result = mysqli_query($link, "SELECT * FROM press ORDER BY press_date DESC");
	$result2 = mysqli_query($link, "SELECT * FROM event ORDER BY event_date DESC");
	$result3 = mysqli_query($link, "SELECT * FROM galleries ORDER BY gallery_id DESC");

	if (!isset($_COOKIE['user'])) {
		die("Identifiant invalide");
	}

Hello, what's the correct use of GD library to compress JPG images please? I am using this upload script with TinyMCE. See below :

I have this snippet but it doesn't compress the image:

		// Accept upload if there was no origin, or if it is an accepted origin
		// If image is JPEG compress with GD library
		$filetowrite = $imageFolder . $temp['name'];
		if (in_array(strtolower(pathinfo($temp['name'], PATHINFO_EXTENSION)), array("jpg", "jpeg"))) {
		imagejpeg($temp['tmp_name'], $filetowrite, 75);
		} else {
		move_uploaded_file($temp['tmp_name'], $filetowrite);
		}

<?php
	$accepted_origins = array("http://localhost", "http://127.0.0.1", "http://192.168.1.1", "http://example.com");

	$month = strtolower(date('M'));
	$year = date('Y');
	$newspath = "img/news/";

	if (!is_dir("$newspath/$year/$month")) {
    mkdir("$newspath/$year/$month", 0777, true);
}
	$imageFolder = "$newspath/$year/$month/";

	reset ($_FILES);
	$temp = current($_FILES);
	if (is_uploaded_file($temp['tmp_name'])){
		if (isset($_SERVER['HTTP_ORIGIN'])) {
			// same-origin requests won't set an origin. If the origin is set, it must be valid.
			if (in_array($_SERVER['HTTP_ORIGIN'], $accepted_origins)) {
				header('Access-Control-Allow-Origin: ' . $_SERVER['HTTP_ORIGIN']);
			} else {
				header("HTTP/1.1 403 Origin Denied");
				return;
			}
		}

		/*
			If your script needs to receive cookies, set images_upload_credentials : true in
			the configuration and enable the following two headers.
		*/
		// header('Access-Control-Allow-Credentials: true');
		// header('P3P: CP="There is no P3P policy."');

		// Sanitize input
		if (preg_match("/([^\w\s\d\-_~,;:\[\]\(\).])|([\.]{2,})/", $temp['name'])) {
				header("HTTP/1.1 400 Invalid file name.");
				return;
		}

		// Verify extension
		if (!in_array(strtolower(pathinfo($temp['name'], PATHINFO_EXTENSION)), array("gif", "jpg", "jpeg", "png"))) {
				header("HTTP/1.1 400 Invalid extension.");
				return;
		}

		// Accept upload if there was no origin, or if it is an accepted origin
		// If image is JPEG compress with GD library
		$filetowrite = $imageFolder . $temp['name'];
		if (in_array(strtolower(pathinfo($temp['name'], PATHINFO_EXTENSION)), array("jpg", "jpeg"))) {
		imagejpeg($temp['tmp_name'], $filetowrite, 75);
		} else {
		move_uploaded_file($temp['tmp_name'], $filetowrite);
		}
		// Respond to the successful upload with JSON.
		// Use a location key to specify the path to the saved image resource.
		// { location : '/your/uploaded/image/file'}
		// echo json_encode(array('location' => $filetowrite));

		$passpath = $year.'/'.$month.'/'.$temp['name'];

		echo json_encode(array('location' => $passpath));
	} else {
		// Notify editor that the upload failed
		header("HTTP/1.1 500 Server Error");
	}
?>

 

I want to create a media library in the CMS, similar to how it is in WordPress but custom-coded in PHP on my own site.

Can this be done simply with a database connection or will the images need to be uploaded to a server?

Bit confused as to how it works and which is the best way to go about it.

Thanks for any help.

GD Library Pattern Background ?

Hi all

I have a simple page here that uses the GD Library
to display text in a selected font and size etc.

http://www.ttmt.org.uk/forum/

At moment the stripped background goes from the code.
Is there a way to have an image as the background instead
of the stripped background.

PHP code

Code: [Select]
<?php
        
header('Content-Type: image/png');

$im = imagecreatetruecolor(900, 215);

$w = imagecolorallocate($im, 255, 255, 255);
$c = imagecolorallocate($im, 220, 220, 220);
$black = imagecolorallocatealpha($im, 0, 0, 0, 20);
$style = array($w,$w,$w,$c,$c,$c);
ImageSetStyle($im, $style);

ImageLine($image, 100, 0, 50, 50, IMG_COLOR_STYLED);
imagefilledrectangle($im, 0, 0, 900, 214, IMG_COLOR_STYLED);
    
  $text = $_GET['text'];
$textSize = $_GET['size'];
$font = $_GET['font'];
  
  imagefttext($im, $textSize, 0, 15, 165, $black, $font, $text);

imagepng($im);

imagedestroy($im);

?>
