Apostrophe Error In Contact Form

kerner · November 12, 2012, 8:42pm

I’m using a pre-made contact form I found online. It generates an “Invalid characters” error whenever sending a message containing “that’s” instead of “thats”, “can’t” instead of cant, etc.

How can I remedy this?

…Thanks:

Sounds like you just need to add the quote into your regex. For example:

Change this:

[php]’/^([\w$&!?.,-\s:/]+)\z/’[/php]

To this:

[php]’/^([\w$&!?.,-\s:/’]+)\z/’[/php]

You will notice the additional ’ at the end

Thanks for your suggestion… unfortunately I couldn’t get it to work. I replaced the code in the line below as directed but I still get the same error.

Am I missing something?

if(!preg_match('/^([\w$&!?.,-\s\:\/\']+)\z/',$xa)){die('<h1>Invalid characters ( # @ ^ &#38;#39; " \ * = ; % < > ` ~ + ) entered in text area (for example if you wrote the word that&#38;#39;s take out the &#38;#39;). Please go back and fix, Then click send <span>(!)</span></h1>');}}

You have two different errors that both say “Invalid characters” - which one are you getting?

kerner · November 14, 2012, 7:41pm

Sorry, I should have been more specific. An “invalid” entry in the message field results in:

“Invalid characters ( # @ ^ ’ " \ * = ; % < > ` ~ + ) entered in text area
(for example if you wrote the word that’s take out the '). Please go back and fix, Then click send!”

m11 · November 14, 2012, 7:59pm

Works fine for me. You must have a different character causing the problem.

[php]
function txar($xa) {
if (!preg_match(’/^([\w$&!?.,-\s:/’]+)\z/’,$xa)) {
die(‘

Invalid characters ( # @ ^ &#39; " \ * = ; % < > ` ~ + ) entered in text area (for example if you wrote the word that&#39;s take out the &#39;). Please go back and fix, Then click send (!)

’);
}
}
txar(“test’in…”); // no error
[/php]

Entering only the word “that’s” in the message box produces the error. Entering only the word “thats” does not.

Months later and I am STILL struggling with this issue. Please …can anyone help?

Thank You

I’m sorry unless I can duplicate your problem I can’t help.

Belated follow up…

I eventually gave up on trying to get this buggy form code to work properly. I ended up using “Fast Secure Contact Form” which works very well. I hope this helps someone else…
