1. Instead of using header function, use the following one:
echo '<META HTTP-EQUIV="REFRESH" CONTENT="0;URL=payment.php?showmsg=1">';
exit;
2. Use the following JS function for non-space alphanumeric data:
function nameCheck(fieldval) {
var fieldchar;
for(var j=0; j < fieldval.length; j++) {
fieldchar = fieldval.charAt(j).charCodeAt(0);
// 65 to 90(a to z) // 97 to 122(A to Z) // 48 to 57(0 to 9)
if ((fieldchar > 64 && fieldchar < 91) || (fieldchar > 96 && fieldchar < 123) || (fieldchar > 47 && fieldchar < 58)) {
;
}
else {
return false;
}
}
return true;
}

Subject: question about header and validation
1.
i have a question about using header("Location: filename.html" ); in
php with my present code i have a few echo statements followed by
header("Location: filename.html" ); because i have echo
statements before header("Location: filename.html" ); i am getting an
error that headers have already been sent. i cannot
remove the echo statements as they are doing an important task. based
on this situation i can use echo followed by the html
code for the filename in filename.html if i do this the code will run
into a few 100's of lines and due to this i would like
to use header("Location: filename.html" );
i have tried the following code and it works =
echo " <form name='errorpage' action='error. php' method='post' >
</form>
<script type='text/javascri pt' language='javascrip t'>
document.errorpage. submit(); </script> ";
however if javascript is turned off this redirection will not work.
could you please suggest if there is an alternative to using echo
statement first followed by
header("Location: filename.html" );
2.
i am using the following php validation for forms which is not working
very well
a)
$specialcharacters = '#^([a-zA-Z0- 9]+)$#';
with this code for a name if i type "first name" with a space it is
considering the space and treating as a special character
however it should validate for letters and numbers only. how can i
write '/^[a-zA-Z]+ $/'; to ignore spaces
b)
$firstnamecheck = '/^[a-zA-Z]+ $/';
with this code if i type for example "first name" as per the error is
states that the string needs to contain letters. though
i typed letters because of the space it is not treating as letters.
how can i rewrite this '/^[a-zA-Z]+ $/';
please advice.
thanks.
