But we can not modify valid_url function as it is drupal core function. But how should i modify the code of valid_url function to allow the space
function valid_url($url, $absolute = FALSE) {
if ($absolute) {
return (bool)preg_match("
/^ # Start at the beginning of the text
(?:ftp|https?|feed):\/\/ # Look for ftp, http, https or feed schemes
(?: # Userinfo (optional) which is typically
(?:(?:[\w\.\-\+!$&'\(\)*\+,;=]|%[0-9a-f]{2})+:)* # a username or a username and password
(?:[\w\.\-\+%!$&'\(\)*\+,;=]|%[0-9a-f]{2})+@ # combination
)?
(?:
(?:[a-z0-9\-\.]|%[0-9a-f]{2})+ # A domain name or a IPv4 address
|(?:\[(?:[0-9a-f]{0,4}:)*(?:[0-9a-f]{0,4})\]) # or a well formed IPv6 address
)
(?::[0-9]+)? # Server port number (optional)
(?:[\/|\?]
(?:[\w#!:\.\?\+=&@$'~*,;\/\(\)\[\]\-]|%[0-9a-f]{2}) # The path and query (optional)
*)?
$/xi", $url);
}
else {
return (bool)preg_match("/^(?:[\w#!:\.\?\+=&@$'~*,;\/\(\)\[\]\-]|%[0-9a-f]{2})+$/i", $url);
}
}I will create my own function with modified code. Can you guide me how to modify code it so i can allow some space in url.
