Image Resize and reCaptcha w/Optional Upload

Hi, I'm a newbie. Fairly new to PHP/Joomla as well, so forgive my terminology. I actually have two issues, and will be glad to post them separately, if you like.

I have created a form that uploads to a table I created, the updates that table with the current userid. I also have a file upload for an image and reCaptcha. The image resize plugin makes a thumbnail. It works fine when everything is entered correctly and a file selected to upload.

However, I get errors from the resize plugin when I test the form and do not upload an image. I need to make the upload optional, and put a default filename in the database without making a thumbnail.

Also, if I enter everything, but an incorrect reCaptcha code, the reCaptcha section does not republish. Instead I get the plugin text {ReCaptcha}

The site is on my local machine right now, but here is the code. Much thanks in advance.

Hi xlnce,

You are getting PHP 'Warnings' that something *might* be wrong - technically these aren't errors, they just mess up your page. And if the plugin were better coded they wouldn't appear.

Set your site Error Reporting to System Default (or possibly None) and they should disappear.

Don't know about the ReCaptcha problem - hard to tell without seeing the form. The ChronoForms ImageVerification may be more reliable here.

Hi,
I have the same problem I think!
I found that come from the plug-in and only when we submit the form with out upload an image!....

Can somebody help me?

thanks

Hi there,

I'm having the same problem with the image resize plugin. My upload field is optional, but if you leave it empty the form spits out all those errors when it can't find the file. Everything else still works, I just need to hide the 'errors'!

I tried setting Error Reporting to none, but it didn't work.

Any other suggestions?

Thanks,
-Megan

Hi Megan,

Edit your php.ini file to set the Error Reporting level there. In general a production site shouldn't be showing Notices and Warnings.
