PHP GD Library output an image and text content on same page

Question

I am trying to output an image to a browser and then output HTML (not directly related to the image) on the same page. Is this possible? I am having a heck of a time figurin

Answer 1

Stop and think for a moment. How would you normally embed an image in a HTML file? You create two files: text.html and image.jpg. Same here, you will create two scrips, one that outputs the HTML and one that generates the image. The HTML would look like:

The generateimage.php script only generates the image.

Lets take for example a form that allows the user to create a digital Christmas card: he can select the image and write a personal note beneath it.

form.html:

    Select an image:
    
        Picture of Christmas tree
        Picture of Santa
    


    Write a message:
    
    


    

view_card.php:

  
    Here is your Christmas card:
    


    
    
    
  

generateimage.php:

 'tree.jpg', 'santa' => 'santa.jpg');
if( !isset($allowed_files[$_GET['imgname']])) {
    exit; // Thank you for playing...
}

/* Attempt to open */
$im = @imagecreatefromjpeg($allowed_files[$_GET['imgname']]);

/* See if it failed */
if(!$im){
    /* Create a black image */
    $im  = imagecreatetruecolor(150, 30);
    $bgc = imagecolorallocate($im, 255, 255, 255);
    $tc  = imagecolorallocate($im, 0, 0, 0);
    imagefilledrectangle($im, 0, 0, 150, 30, $bgc);

    /* Output an error message */
    imagestring($im, 1, 5, 5, 'Error loading ' . $imgname, $tc);
}

header('Content-Type: image/jpeg');
imagejpeg($im);
imagedestroy($im);
?>
