Following up on our previous article about preventing fake registrations on PrestaShop, we will now address another pressing issue faced by online store owners. This time, we will discuss fake registrations with names and surnames containing Chinese characters. This is especially relevant for stores that do not cater to clients from countries using Chinese characters.
Why is this a Problem?
Fake registrations can not only distort statistics but also overload the system, creating unnecessary server strain. It's important to understand that if your store does not serve customers from countries using Chinese characters (e.g., China, Japan, Korea), then any such registrations can be safely considered suspicious.
Solution to the Problem
One effective way to combat this issue is to use regular expressions in PHP to check names for the presence of Chinese characters. Below is an example of such an approach:
function containsChineseCharacters($string) {
// Regular expression to check for Chinese characters
$pattern = '/[\x{4e00}-\x{9fff}]/u';
return preg_match($pattern, $string);
}
$input = "滥发电邮aaaaa点com滥发电邮";
if (containsChineseCharacters($input)) {
echo "The string contains Chinese characters.";
} else {
echo "The string does not contain Chinese characters.";
}
In this example, the regular expression '/[\x{4e00}-\x{9fff}]/u' is used to search for characters in the range from U+4E00 to U+9FFF, which covers most modern Chinese characters. The u flag indicates the use of UTF-8 encoding.
How Does It Work?
- Defining the Regular Expression: The regular expression finds characters corresponding to Chinese characters.
- String Check: The
preg_matchfunction checks for the presence of Chinese characters in the name or surname. - Action: If Chinese characters are detected in the string, registration can be blocked, and an error message displayed.
Important Note
This method is suitable only for stores that do not cater to clients from countries using Chinese characters. If you have clients from such countries, you will need to use other methods of data verification and filtering.
Conclusion
Fake registrations can cause significant trouble for online store owners. We hope the proposed method will help you reduce the number of unwanted registrations and improve the quality of your customer service.
