eregi help!

[betamyprice.co.uk]

Hi all, I am new to this board so firstly may I take the opportunity to say hi.

 

Here's my problem and I'm sure to you guys it is only a small one.

 

I am trying to validate entry into a form. I only want the first name to accept Alphabetic characters, along with apostrophes, hyphens and spaces.

 

From a bit of net research I currently have this:

 

if (!eregi("[_a-zA-Z0-9-]", $_POST[first] )) 
{
$_SESSION['errors'].= "*Your name must be alphabetic" . "<br>"; 
}

 

But it doesnt work, can someone help please 

[runnerjp]

(!eregi("/^[a-z0-9]+(?:_[a-z0-9]+)?$/i", $_POST["first"]))) {

 

 

i think!

Afraid it doesn't work Runnerjp!

But thanks for your efforts.

 

I dropped the extra ) that was throwing an error but it is actually saying that the input is incorrect when it isn't!

Try this out.

 

if (!preg_match("/[\w\s-]*/i", $_POST[first] )) 
{
$_SESSION['errors'].= "*Your name must be alphabetic" . "<br>"; 
}

 

I don't know if ereg will work but I'm pretty sure that preg will. Try it and come back to me.

 

Sorry about the error hope you get this edit please edit your reply if you do.

That seems to let everything through you can try for yourself - Fill in the First Name Field

It is so puzzling isn't it!

if (!preg_match("/^[\w\s-]+$/i", $_POST[first] ))

Darkwater you are beautiful!

 

Works almost exactly how I want. except i also need to allow for apostrophes for names such as o'Toole

[dsaba]

if (!preg_match("/^[\w\s-]+$/i", $_POST[first] ))

 

See Character classes.

What exactly are the rules for apostrophes? How many can you have in an approved name..etc.. Where would it be allowed to be placed.. all things to think about.

Simply adding ' to the char class should do the trick, but it would also allow for ''''''''''''''''''''''''' to verify just like it already allows for ------------------- to verify.

<?php if (!preg_match("/^[\w\s-']+$/i", $_POST[first] )) ?>

All over my head I'm afraid my friedn  ???

[betamyprice.co.uk]

ahhhh it's doing my head in, the form is now passing the ' as \'

 

for example in the o'toole example it is POSTing o/'toole

 

 

[betamyprice.co.uk]

Anybody know how to pass an apostrophe as an apostrophe and not as a forward slash and an apostrophe??

 

o\'toole

[effigy]

It might be magic quotes.

[MikeDXUNL]

str_replace('\\', '', $data);

 

 

that should replace the \' in the data
