IPValidator checks if an IP address is technically correct.
Documentation ¶
Requirements ¶
- Yii 1.0 or above
Installation ¶
- Extract the release file under
protected/extensions
Usage ¶
The following model code validates against the ipv4 regex:
public function rules()
{
return array(
array('ipAddr', 'application.extensions.ipvalidator.IPValidator', 'version' => 'v4')
);
}
While the following validates against the ipv6 regex: [php] public function rules() { return array(
array('ipAddr', 'application.extensions.ipvalidator.IPValidator', 'version' => 'v4')
);
}
Change Log ¶
1.1 - ipv4 bug fixed (Thanks to beesnept)
- ipv6 support added (Thanks to Rich Brown for his regex)
1.0 - initial version
Regexp error
I'm sorry I mispelled the syntax, the correct regexp is:
/^(([1-9]?[0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])\.){3}([1-9]?[0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])$/Regexp error
The regular expression is not correct, as it considers IP addresses like 10a0a0a1 as valid.
We need to use . instead of . to match for the dot character so we have to change the regular expression to
/^(([1-9]?[0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5]).){3}([1-9]?[0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])$/
Allow both
I made a patch for allowing both standars (v4 or v6):
