Still new to Codeigniter, finally got around to testing out the captcha helper. Question - any suggestions on improving the readability of the captcha? Thanks for all the responses. -Roberto

What do you mean? You can use a different font also and maybe you need to check this out if you are having troubles setting the font-size. http://ellislab.com/forums/viewthread/224773/ Cheers!

Hi ojcarga! I'm not quite sure how to change the font or the font size. I found this online: http://tutorialsbay.com/codeigniter-capt...y-example/ I tried out the example there and I was happy that I was able to get the captcha on my web page. Changing the font size might help. I looked at the link you typed up, but where would I type that? Would I have to modify some core Codeigniter function? If so, isn't that bad if you want to upgrade later. Thanks again. -Roberto [quote author="ojcarga" date="1348695173"]What do you mean?

Cool! I was able to change the font, and it seems that by doing this, it is a little easier to read from a human stand point. Thanks for your input! -Roberto

Follow up question... What would be the best technique to "refresh" that captcha? I've seen websites where they have a little button right by the captcha image and when you click on it, the captcha is changed. Is there a simple way to do this in Codeigniter? Thanks again. -Roberto

[/quote] Sure, you should change it but not the one in System folder, you should create a new one (a new helper file inside application folder) Go here: http://ellislab.com/codeigniter/user-gui...lpers.html Below this subtitle you will find how you can achieve that. "Extending" Helpers This would keep your "core helper" as they are and will not be a problem for a future upgrade. About the refreshing thing, I have just made the same thing in my current project. I did it this way: A simple anchor that on click event calls a ajax method, this ajax method will call a method in my controller that has a simple call to "create_captcha()" function and then what I return back to the browser is 'image' => $img part and then I just change it in the doom. Let me know if I explained well. Cheers! |
