[SOLVED] Invalid font filename

[jrp91384]

Help Please!

 

I’m receiving the following error.

 

Warning: imagettftext() [function.imagettftext]: Invalid font filename in /home/xxx/public_html/wp-content/plugins/mm-forms/captcha/captcha.php on line 60

 

I have checked and the folder and files needed are writable.

I also contacted my host to see if Truetype was on the server and it is.

 

What else could be causing this? Any help would be greatly appreciated!!

 

Thank you

the font used in imagettftext can't be found or doesn't exists,

goto line 60 of captcha.php and check the 7th parameter to check the name (it maybe missing .ttf), or update to another font

Hi MadTechie

 

I'm not mr. php but the files and paths look correct. Below is the code i have and the ttf files are in a file called gentium. Something strange is one of the fonts in that file is showing. Not sure what font it is but when you refresh the page it changes the captcha image and shows 1 letter sometimes and 2-3 letters another time.

 

Any Ideas?? Thanks for the help!!!!

 

this is line 60

okay, the folder that captcha.php is in,

you should have another folder called 'gentium'

inside that you should have the following fonts

GenAI102.TTF
GenAR102.TTF
GenI102.TTF
GenR102.TTF'

on unix this is case sensitive

 

So for example this path should be valid

/home/xxx/public_html/wp-content/plugins/mm-forms/captcha/gentium/GenAI102.TTF

That is exactly how it is. I have the following.

 

/home/xxx/public_html/wp-content/plugins/mm-forms/captcha/gentium/GenAI102.TTF

/home/xxx/public_html/wp-content/plugins/mm-forms/captcha/cpatcha.php

do you have the other 3 files ?

GenAR102.TTF

GenI102.TTF

GenR102.TTF

[jrp91384]

do you have the other 3 files ?

GenAR102.TTF

GenI102.TTF

GenR102.TTF

 

Yes in the same location.

Okay well that should be fine, of course assuming the case is the same,

it maybe worth connecting via FTP and checking the permission and file size,

while your their upload another font, ie arial.ttf into the captcha folder,

 

then (if no changes were made to the gentium fonts) update captcha.php from

$this->fonts = array(
         dirname(__FILE__) . '/gentium/GenAI102.TTF',
         dirname(__FILE__) . '/gentium/GenAR102.TTF',
         dirname(__FILE__) . '/gentium/GenI102.TTF',
         dirname(__FILE__) . '/gentium/GenR102.TTF');

to

$this->fonts = array(
         dirname(__FILE__) . '/arial.ttf');

 

assuming that works, you can repeat the test with each font,

 

$this->fonts = array(
         dirname(__FILE__) . '/gentium/GenAI102.TTF');

then

$this->fonts = array(
         dirname(__FILE__) . '/gentium/GenAR102.TTF');

etc etc

I will give that a try. Thank you so much for the help!

[jrp91384]

Well not sure why but it works outside the folder. Thank you sooo much for all the help MadTechie!! I really appreciate it
