Creating Images

Greetings learned PHP(eople), I am using the code below to create buttons based on entries that are inserted into a text field from the preceding page. I got this code from my trusty tome "PHP and MySQL Web Development" by Luke Wellign/Laura Thomson. Problem is this : If I type in more than 18 characters the image creation fails with : "The image "http://xxxxxx.xxxx.xx.xx/Generic/Admin/make_buttons.php" cannot be displayed, because it contains errors" When I view the HTML page source code, it simply states "Text given is too large for button" Any ideas on how to make it so that the error I specified comes up and not the "The image "http://xxxxxxx.xxx.xxx.xxx.x blah blah" part..... Here`s the code : ------- <?php Header('Content-type: image/png'); //Posted from previous page //Button text and colour $button_text = $HTTP_POST_VARS['button_text']; $colour = $HTTP_POST_VARS['colour']; if (empty($button_text) || empty($colour)) { echo 'Could not create button'; exit; } //Create image from existing image $image = imagecreatefrompng ('images/purple.png'); $image_width = ImageSX($image); $image_height = ImageSY($image); //Image needs 18 pixel margin in from the edge image $image_width_wo_margins = $image_width - (2 * 18); $image_height_wo_margins = $image_height - (2 * 18); //Work out if the font size will fit and make it //smaller until it does. Start with large size and scale down $font_size = 33; //Set font name and location $fontname = "/home/data/ClientWebs/chrisplay/Generic/Admin/a_d_mono.ttf"; do { $font_size--; //Find out the size of the text at that font size $bbox = imagettfbbox ($font_size, 0, $fontname, $button_text); $right_text = $bbox[2]; //Right co-ordinate $left_text = $bbox[0]; //Left co-ordinate $width_text = $right_text - $left_text; //How wide is it ? $height_text = abs($bbox[7] - $bbox[1]); //How tall is it ? } while ($font_size > 8 && ($height_text > $image_height_wo_margins || $width_text > $image_width_wo_margins) ); if ($height_text > $image_height_wo_margins || $width_text > $image_width_wo_margins) { //No readable font size will fit on button echo 'Text given is too large for button'; } else { //The font size fits //Now where to put it $text_x = $image_width/2.0 - $width_text/2.0; $text_y = $image_height/2.0 - $height_text/2.0; if ($left_text < 0 ) $text_x += abs($left_text); //Factor for left overhang $above_line_text = abs($bbox[7]); //How far above the baseline $text_y += $above_line_text; //Add baseline factor $text_y -= 2; //Adjustment factor for shape of our template $white = ImageColorAllocate($image, 0,0,255); ImageTTFText ($image, $font_size, 0, $text_x, $text_y, $white, $fontname , $button_text); ImagePng($image); } ImageDestroy($image); ?> Thanks in advance for any assistance......
