Email Verification - No Number In Position 1 Of Field

[arccomp]

I have this line of code to check for email. I need to make sure it fails if there is a number in the first location. I am adding the email address to a linux server from the form and the linux server rejects the email address if there is a number in the first location of the text field. Any help would be appreciated.

 

public function isValidEmail($in_email)

{

if (empty($in_email))

{

return false;

}

else

{

if (!preg_match("(^[-\w\.]+@([-a-z0-9]+\.)+[a-z]{2,4}$)i", $in_email))

{

return false;

}

else

{

return true;

}

}

}

If you only want to check the first character then use braces to grab it and validate it

if(is_int($emailInput[0]))

Thanks - will try this - sort of new at php. Will let you know. It seems the problem you refered to me above is different so I was a little confused by that.

I tried that code add to what I had attached and it breaks the site. Not quite sure where I went wrong? Thoughts?

Surely you can do better than "it breaks the site".

The page with the form that includes and calls this function goes to a white screen. Trying to figure out if I can debug it.

 

This is the code:

 

public function isValidEmail($in_email)

{

if (is_int($in_email[0]))

{

return false;

}

else

{

if (empty($in_email))

{

return false;

}

else

{

if (!preg_match("(^[-\w\.]+@([-a-z0-9]+\.)+[a-z]{2,4}$)i", $in_email))

{

return false;

}

else

{

return true;

}

}

}

You missed a closing curly brace.
