To all Gentlemen and beautiful Ladies,

As per my subject, we have some idiots sending us HTML and clear text spam via Message [text] box we have in contact form. They paste hundreds of lines and we get the crap. In the Tel number field, they only bother to enter 4 or 5 characters to get validated and it's all done.

How can I make their time wasted and protect both, tel phone number with min and max characters as well as Message field. Crying for help!

Thank you all.
RSFP is a wonderful product

Hello aakmita,

Spam can occur even with the most advanced anti-spam methods. There will always be users who will try to exploit certain security holes in Joomla! by manually submitting the form with different code.

In the case of the Telephone number, at the moment this post is made, this type of validation uses the following regular expression:

/\(?\b[0-9]{3}\)?[-. ]?[0-9]{3}[-. ]?[0-9]{4}\b/i

... which should validate values like the following:

034.231.4834

... but not something like this:

4834

To limit the characters in the text field, you can simply add a PHP "Script called on form process" in the Components > RSForm!Pro > Manage Forms > edit your form > Properties > PHP Scripts area (second textarea).

Something like the following should do the trick:

Please remember to adjust the script to your specific scenario (replace "name_of_your_textarea_field" and minimum/maximum_number_of_characters)

PS: Adding a ReCAPTCHA field should also help you greatly reduce the number of spam submits on your form. For more info, please visit:

Thank you Cristian

That works perfectly!

Cheers.

I got this code to work, but how do you get it to give a custom error message, instead of "invalid input". I want them to know they have too many characters in the box.

Thanks,

Hello,

The invalidation message can be simply edited from your field configuration (backend > Components > RSForm!Pro > Manage Forms > your form > edit your field > "Validation" tab > Validation message).

Hi

Does anyone know if it's possible to validate that the telephone number field starts with a '0' rather than a minimum number of digits.

I'd be grateful for any ideas.

Thanks

Dave
