我购买了联系表.很棒的小东西,但我需要转换电话号码的验证以允许英国号码格式 - 换句话说,允许空格.
I purchased a contact form. Great little thing but I need to convert the validation for the phone number to allow for UK number formats - in other words, to allow for spaces.
现在它验证时没有空格,并且至少有 8 个字符:
Right now it validates without spaces and has a minimum length of 8 characters:
if(is_numeric($phone))
{
if(!$phone || strlen($phone) < 8)
{
$error .= "Please enter your phone number without spaces.<br />";
}
}
else
{
$error .= "Please enter numeric characters in the phone number field.<br />";
}
电话号码对于正则表达式模式来说通常很糟糕,而这正是你所需要的.
Phone numbers are typically horrible for regex patterns, which is what you will need.
以这种模式为例:
$pattern = "/^(+44s?7d{3}|(?07d{3})?)s?d{3}s?d{3}$/";
$match = preg_match($pattern,$input);
if ($match != false) {
// We have a valid phone number
} else {
// We have an invalid phone number
}
该模式将与是否包含 +44 匹配,例如
That pattern will match with +44 included or not e.g.
所有这些都会匹配:
07222 555555
(07222) 555555
+44 7222 555 555
这些不会
7222 555555
+44 07222 555555
(+447222) 555555
有很多网站提供正则表达式的教程/备忘单等.尝试其中一些:
There are a load of sites that offer tutorials / cheat sheets etc. for regular expressions try some of these:
