preg_match help to allow enter in textarea box

[CBG]

Hi,

 

I currently have the below code to check the textarea box.

 

if (preg_match("#^[a-zA-Z0-9 .,?_/'!£$%&*()+=-]+$#", $msgs)) {
	// Everything ok. Do nothing and continue
} else {
	echo "Message is not in correct format.<br>You can use a-z A-Z 0-9 . , ? _ / ' ! £ $ % * () + = - Only";

 

However the problem is, when putting enter in the message if fails

For example if I put the message

 

this

message

doesnt

work

 

It fails and echo the else

 

But if I put

this message does work

 

It is ok

 

 

Could someone tell me what extra bit of code I need to add to the preg_match and where.

 

Thanks for the help

You need to add the 's' modifier after your closing delimiter:

 

#^[a-zA-Z0-9 .,?_/'!£$%&*()+=-]+$#s

Thanks for the reply, I have just tried this and I get the same problem.

I tried with m modifer but I get the reverse problem

Ah. I didn't look to much at the regex before, but you need to escape special characters to use them as literals, and since you're not using the dot to match any character (instead as a literal), you also need new line / return characters in your regex, instead of the 's' modifier. Try this:

 

#^[a-zA-Z0-9 \.,\?_/'!£\$%&*()+=\r\n-]+$#

[Adam]

Also if you add "\w" (word-characters) to the regex, you can remove a-z A-Z 0-9 and _ .. to simplify it a little.

That worked, great thanks for the help

Will look at the /w later.

 

Thanks agin for the help
