sinfield Posted March 16, 2006 Share Posted March 16, 2006 I am trying to assign a variable "$fullname" from database, and then output that variable text content to png. The $fullname script works if I echo it to the screen. And the text-to-png part works if I either manually declare the text to be transformed or if I manually declare the value of the $fullname variable (see commented test in code). But if I use two together to dynamically set the value of the $fullname variable, it does not work. Is there something glaring and obvious I am missing?I know the query is not pretty. The DB schema I am working with is ... bad. But it is what I have to work with right now.Here's my code:I was unable to post code, so check it here:[a href=\"http://bogobug.com/uname_to_png.txt\" target=\"_blank\"]http://bogobug.com/uname_to_png.txt[/a] Link to comment https://forums.phpfreaks.com/topic/5115-variable-text-to-png/ Share on other sites More sharing options...
sinfield Posted March 17, 2006 Author Share Posted March 17, 2006 Ok, I managed to work it out. The script was sending headers to the browser. Since all I need it to do is to output the png to a file, rather than to the browser, I just commented out the header declaration. All is well now.On to further refinements!

Barand Posted March 17, 2006 Share Posted March 17, 2006 If you want tp create them on-the-fly then save this bit in a separate script, say, "imagetext.php"[code]<?php$fullname = $_GET['fn'];// create an image with width 'x', height 'y'$image = imagecreate(200, 100);// create a background color and then set it to transparent$background = imagecolorallocate($image, 255, 255, 255);ImageColorTransparent($image, $background);ImageInterlace($image, false);// set black color for the text$black = imagecolorallocate($image, 0, 0, 0);// write the variable string to the image// the top left of the text is at the position (10, 2)imagestring($image, 4, 10, 2, $fullname, $black);// tell the browser what we're sending itHeader('Content-type: image/png');// output the image as a png// imagepng($image);imagepng($image);// tidy upimagedestroy($image);?>[/code]And in main script, to display the image[code]echo "<IMG src='imagetext.php?fn=$fullname'>";[/code] Link to comment https://forums.phpfreaks.com/topic/5115-variable-text-to-png/#findComment-18300 Share on other sites More sharing options...
