Languages :: PHP :: Bizarre PHP errors...?
By: Kre8	Date: 05/08/2003 00:00:00	Points: 300	Status: Answered Quality : Excellent
The exact warnings outputed is Warning: in /usr/www/virtual/our/<A HREF="http://www.domain.com/admin/galz1/uploader.php">www.domain.com/admin/galz1/uploader.php</a> on line 33 Warning: src_img in /usr/www/virtual/our/<A HREF="http://www.domain.com/admin/galz1/uploader.php">www.domain.com/admin/galz1/uploader.php</a> on line 60 Not sure if the 1st warning will display properly but it is Warning: a square box in /usr/ww/ on line 33 The two lines in question that have recently started outputting this warning are as below line 33 $box = imagettfbbox ($text_size,0,$font_file,$copyright_text); line 60 $text1 = imagettftext($src_img,$size,$angle,$xc,$yc,$outlinecol,$fontfile,$text); As you can see both lines are to do with true type fonts on images so im guessing thats where the problem lies.:) Since the errors started appearing, the script has stopped adding the copyright text that it should do. Any ideas on whats causing the errors and how i can get it working again? Thanks:)

Did the script work before and then just suddenly stop? Make sure the font_file is located where you say it is located. In line 33 you are using $font_file and in line 60 you are using $fontfile....is this intentional? Line 60 looks like it is having problems with the $src_img...is that setup correctly with an imagecreate() ?

Hi wtgee, Yeah, the script worked fine for 3 months and then about a week ago it decided to start throwing up warnings:( The actual script still works in that it takes an uploaded file, resizes it and copies it elsewhere, however it should also add copyright text which it isnt and instead outputting the warnings... Sorry about the font_file, line 60 is actually within a function that gets passed $fontfile. I've put together a test script using the basics of the actual script and enclosed it below, however this script is still outputting the warnings:( $img = imagecreate(100,50); $white = imagecolorallocate($img,255,255,255); $black = imagecolorallocate($img,0,0,0); $font_file = '/www/virtual/absolute/path/to/<A HREF="http://www.our-domain.com/php_font_upload_directory/arial.ttf">www.our-domain.com/php_font_upload_directory/arial.ttf</a>'; $font_size = 12; $angle = 0; $horz_pos = 20; $vert_pos = 25; $text = "Testing"; imagerectangle($img,0,0,99,49,$black); ImageTTFText($img, $font_size, $angle, $horz_pos, $vert_pos, $black, $font_file, $text); header("Content-type:image/jpeg"); imagejpeg($img); imagedestroy($img); I've even tried the simple examples from php.net for imagettfftext but still get same warnings:( I did find this <A HREF="http://bugs.php.net/bug.php?id=15568">http://bugs.php.net/bug.php?id=15568</a> which suggest is possible a bug in an older version of php, but the server in question is running PHP 4.2.3

Is it a hosted server? If so they might have recently upgraded to 4.3 which might have an error somewhere. I will check out the script in a bit. Apparently I am supposed to be working or something. :)

Try using a different font, or downloading a replacement arial.ttf font.

check this line in your editor : line 33 $box = imagettfbbox ($text_size,0,$font_file,$copyright_text); searching for binary unprintable characters in a bad location *or* check that no variable in the call "suddenly" lost it's value and contains binary

Hi wtgee, Yes its a hosted server, though is currently running PHP 4.2.3, cheers for taking a look. VGR, i rewrote the script and included in above post to explicitly set the variables before the call and still get the errors:( Cheers:)

and if you isolate the block of lines containing the "error" ? Does the error still show ?

By: wtgee	Date: 06/08/2003 01:24:00		Type : Comment
I don't know...the fact that you coldn't create the box and couldn't write the text tells me it is something with the TTF from your server. Can you do just an imagestring() and get it to display properly? I would ask your server if they have made any changes and see what they say.

usually, a web host answers "we haven't changed anything" ;-) especially if they did :D

By: VGR	Date: 06/08/2003 01:44:00		Type : Answer
well, the problem is that the error messages seem to indicate a problematic PHP installation... Warning: in ... Warning: src_img in ... have no sense at all and are not errors I suggest they restart the webserver :D

I agree that the problem is not yours but theirs (isn't it always that way).

wtgee & VGR, I can use other image drawing functions fine and it draws the box in the test script, it just refuses to budge about the text thing though... I have already asked host and suprise, suprise they deny all knowledge of having changed anything lol. Going to try using imagestring() instead and see if can work a way around it:) Will let you know and split points:)
