Ask about 1.7.8.2 php 7.4

How can you prevent #/$%* being entered in a contact form
reCAPTCHA was not the solution

You can write your own kavascript that will check the characters and disable the send button.

If you modify the controller, the filter will not work. Prestashop 1.6 is not secure.

What should I do on the site. You can't download anything. Help
It's for 1.7.8.2

[ps8modules.com]

And why don't you all write down for which version of Prestashop you need a solution.

Eg.

[1.7.8.2] Spam question. Contact form. reCAPTCHA

[Hans Wolf]

I changed it

[ps8modules.com]

contactform.php

Find: function sendMessage().

Add your message control.

Add after $clientTokenTTL:

$restricts = ['#','/','$','%','*'];
$isValidMessage = true;
foreach ($restricts as $restrict) {
  if (strpos($message, $restrict) !== false){$isValidMessage = false;}
}

And update:

elseif (!Validate::isCleanHtml($message))

To:

elseif (!Validate::isCleanHtml($message) || $isValidMessage == false)

If you need to find out if a message contains HTML tags, you can create your own function.
E.g.:

public function isHtmlTags($message)
{
  	if (preg_match("/<[^<]+>/", $message)){
    	return true; // found html tags
	} else {
    	return false; // not found html tags
	}
}

There are several options.
But this is the simplest solution.
Add text to the Terms and conditions of use that HTML tags and special characters are prohibited in the contact form.
Do not put a warning in the contact form.

Hello @ps8moduly.cz,

many thanks for this BUT it didn't work for me.

I entered the code in the correct places but when I tested, the messages were sent without error/warning.

It should be the correct file as it matched yours and also as I made a typo and forgot a brace, it didn't work, until I corrected.

/modules/contactform/contactform.php

Any ideas?

Also, if anyone can point me to a maths question easy code guide for prestashop 1.7.6.7, I would be grateful.
