GuitarGod Posted September 24, 2006 Share Posted September 24, 2006 Hey guys,I recently tried to create an image which would change it's text, font, background-colour etc when the page was refreshed (similar to a confirmation code image that you often see on registration pages. I put the code in a file named [i]confirmation_code.php[/i], when i visit this file, the image works fine, but when i include the file on other pages, i get an error code and the image doesn't work either. Can anyone please help me or tell me what i'm doing wrong?The code for confirmation_code.php:[code]<?php$chars = "abcdefghjkmnpqrstuvwxyzABCDEFGHJKMNPQRSTUVWXYZ23456789"; srand((double)microtime()*1000000); $i = 0; $code_length = 5; $code_return = ' ' ; while ($i <= $code_length) { $num = rand() % 33; $tmp = substr($chars, $num, 1); $code_return = $code_return . $tmp; $i++; } // ---- // Generate the text angle for ($i = 0; $i < 15; $i++) { $angle[] = $i; } srand ((double) microtime() * 1000000); $random_angle = rand(0,count($angle)-1); // ---- // Generate the background image colour $bg_colour[] = array("255", "255", "204"); $bg_colour[] = array("255", "255", "153"); $bg_colour[] = array("255", "255", "102"); $bg_colour[] = array("255", "255", "51"); $bg_colour[] = array("255", "255", "0"); $bg_colour[] = array("255", "204", "255"); $bg_colour[] = array("255", "204", "204"); $bg_colour[] = array("255", "204", "153"); $bg_colour[] = array("255", "204", "102"); $bg_colour[] = array("255", "204", "51"); $bg_colour[] = array("255", "204", "0"); $bg_colour[] = array("255", "153", "255"); $bg_colour[] = array("255", "153", "204"); $bg_colour[] = array("255", "153", "153"); $bg_colour[] = array("255", "153", "102"); $bg_colour[] = array("255", "153", "51"); $bg_colour[] = array("255", "153", "0"); $bg_colour[] = array("255", "102", "255"); $bg_colour[] = array("255", "102", "204"); $bg_colour[] = array("255", "102", "153"); $bg_colour[] = array("255", "102", "102"); $bg_colour[] = array("255", "102", "51"); $bg_colour[] = array("255", "102", "0"); $bg_colour[] = array("255", "51", "255"); $bg_colour[] = array("255", "51", "204"); $bg_colour[] = array("255", "51", "153"); $bg_colour[] = array("255", "51", "102"); $bg_colour[] = array("255", "51", "51"); $bg_colour[] = array("255", "51", "0"); $bg_colour[] = array("255", "0", "255"); $bg_colour[] = array("255", "0", "204"); $bg_colour[] = array("255", "0", "153"); $bg_colour[] = array("255", "0", "102"); $bg_colour[] = array("255", "0", "51"); $bg_colour[] = array("255", "0", "0"); srand ((double) microtime() * 1000000); $random_bg_colour = rand(0,count($bg_colour)-1); // ---- // Generate the text colour $txt_colour[] = array("0", "255", "204"); $txt_colour[] = array("0", "255", "153"); $txt_colour[] = array("0", "255", "102"); $txt_colour[] = array("0", "255", "51"); $txt_colour[] = array("0", "255", "0"); $txt_colour[] = array("0", "204", "255"); $txt_colour[] = array("0", "204", "204"); $txt_colour[] = array("0", "204", "153"); $txt_colour[] = array("0", "204", "102"); $txt_colour[] = array("0", "204", "51"); $txt_colour[] = array("0", "204", "0"); $txt_colour[] = array("0", "153", "255"); $txt_colour[] = array("0", "153", "204"); $txt_colour[] = array("0", "153", "153"); $txt_colour[] = array("0", "153", "102"); $txt_colour[] = array("0", "153", "51"); $txt_colour[] = array("0", "153", "0"); $txt_colour[] = array("0", "102", "255"); $txt_colour[] = array("0", "102", "204"); $txt_colour[] = array("0", "102", "153"); $txt_colour[] = array("0", "102", "102"); $txt_colour[] = array("0", "102", "51"); $txt_colour[] = array("0", "102", "0"); $txt_colour[] = array("0", "51", "255"); $txt_colour[] = array("0", "51", "204"); $txt_colour[] = array("0", "51", "153"); $txt_colour[] = array("0", "51", "102"); $txt_colour[] = array("0", "51", "51"); $txt_colour[] = array("0", "51", "0"); $txt_colour[] = array("0", "0", "255"); $txt_colour[] = array("0", "0", "204"); $txt_colour[] = array("0", "0", "153"); $txt_colour[] = array("0", "0", "102"); $txt_colour[] = array("0", "0", "51"); $txt_colour[] = array("0", "0", "0"); srand ((double) microtime() * 1000000); $random_txt_colour = rand(0,count($txt_colour)-1); // ---- // Generate the font for the image $font[] = "georgia.ttf"; $font[] = "comic.ttf"; $font[] = "trebucbi.ttf"; $font[] = "timesbd.ttf"; $font[] = "impact.ttf"; srand ((double) microtime() * 1000000); $random_font = rand(0,count($font)-1); // ---- // Now that the code has been generated, time to place it onto an image Header("Content-type: image/png"); $w = 250; $h = 70; $im = ImageCreate($w, $h); $background_color = imagecolorallocate($im, $bg_colour[$random_bg_colour][0], $bg_colour[$random_bg_colour][1], $bg_colour[$random_bg_colour][2]); $text = ImageColorAllocate($im, $txt_colour[$random_txt_colour][0], $txt_colour[$random_txt_colour][1], $txt_colour[$random_txt_colour][2]); ImageRectangle($im,0,0,$w - 1,$h - 1,$BorderColor); ImageFtText ($im, 16, $random_angle, 50, 50, $text, "$font[$random_font]", "$code_return", array()); ImagePng($im); ImageDestroy($im);?>[/code]MOD EDIT : Please use code tags Quote Link to comment Share on other sites More sharing options...
Barand Posted September 24, 2006 Share Posted September 24, 2006 Have you tried placing it with<img src="confirmation_code.php"> Quote Link to comment Share on other sites More sharing options...
Barand Posted September 24, 2006 Share Posted September 24, 2006 BTW,You place the image on the page and the user types the same characters into a text box and submits the form.With your image code, how do you now verify the user entered the same characters?

GuitarGod Posted September 24, 2006 Author Share Posted September 24, 2006 It works!! :D Dude, if you were here i'd bow down to you!!As for your question, what i planned to do was create a session containing the generated code, then compare the code the user has entered with the session.

Barand Posted September 24, 2006 Share Posted September 24, 2006 You could generate the random code outside the image, store in session var then pass it to the image code$key = gen_rand_string();$_SESSION['key'] = $key;echo "<img src=\"confirmation_code.php?text=$key\">";EDIT : Ignore this. Better to generate and save from within the image code, then it doesn't appear in page source. Quote Link to comment Share on other sites More sharing options...
