问题描述
我想做的是清理/验证电话号码输入只允许数字。
我想我需要使用 FILTER_SANITIZE_NUMBER_INT 但我不知道在哪里或如何使用它。
这是我的代码：
？php
//将电子邮件地址替换为应接收联系表单查询的电子邮件地址。
define（'TO_EMAIL'，'########'）;
$ aErrors = array（）;
$ aResults = array（）;
/ *函数* /
函数stripslashes_if_required（$ sContent）{
if（get_magic_quotes_gpc（））{
return stripslashes $ sContent）;
} else {
return $ sContent;
}
}
函数get_current_url_path（）{
$ sPageUrl =http：//$ _ SERVER [SERVER_NAME] $ _SERVER [ REQUEST_URI];
$ count = strlen（basename（$ sPageUrl））;
$ sPagePath = substr（$ sPageUrl，0， - $ count）;
return $ sPagePath;
}
函数输出（$ aErrors = array（），$ aResults = array（））{//输出JSON
$ bFormSent =空（$ aErrors ）？真假;
$ aCombinedData = array（
'bFormSent'=> $ bFormSent，
'aErrors'=> $ aErrors，
'aResults'=> $ aResults
）;
header（'Content-type：application / json'）;
echo json_encode（$ aCombinedData）;
退出;
}
//检查支持的PHP版本
if（version_compare（PHP_VERSION，'5.2.0'，'<'））{//需要PHP 5.2此脚本中使用的安全过滤器
$ aErrors [] ='不支持的PHP版本。 < br />< em>最低要求是5.2。< br />您的版本是'。 PHP_VERSION。'。< / em>';
输出（$ aErrors）;
}
if（！empty（$ _ POST））{// Form posted？
//获取已发布数据的安全消毒版本
$ sFromEmail = filter_input（INPUT_POST，'email'，FILTER_SANITIZE_EMAIL）;
$ sFromName = filter_input（INPUT_POST，'name'，FILTER_SANITIZE_STRING，FILTER_FLAG_STRIP_LOW）;
$ sMessage =Name：.stripslashes_if_required（$ _ POST ['name']）;
$ sMessage。=\r\\\
Email：.stripslashes_if_required（$ _ POST ['email']）;
$ sMessage。=\r\\\
Business：.stripslashes_if_required（$ _ POST ['business']）;
$ sMessage。=\r\\\
Address：.stripslashes_if_required（$ _ POST ['address']）;
$ sMessage。=\r\\\
Phone：.stripslashes_if_required（$ _ POST ['phone']）;
$ sMessage。=\r\\\
Message：.stripslashes_if_required（$ _ POST ['message']）;
$ sMessage。=\r\\\
- \r\\\
Email从发送。 get_current_url_path（）;
$ sHeaders =From：'$ sFromName'< $ sFromEmail>。\r\\\
;
$ sHeaders。=Reply-To：'$ sFromName'< $ sFromEmail>;
if（filter_var（$ sFromEmail，FILTER_VALIDATE_EMAIL））{//有效的电子邮件格式？
$ bMailSent = mail（TO_EMAIL，$ sFromName的新查询，$ sMessage，$ sHeaders）;
if（$ bMailSent）{
$ aResults [] =发送消息，谢谢！
} else {
$ aErrors [] =邮件未发送，请稍后再试。
}
} else {
$ aErrors [] ='无效的电子邮件地址'。
}
} else {// Nothing posted
$ aErrors [] ='空数据被提交。
}
输出（$ aErrors，$ aResults）;你有没有看过PHP的 preg_replace 功能？您可以使用 preg_replace（'/ [^ 0-9] /'，''，$ _POST ['phone']）删除任何非数字字符。 / p>
过滤掉字符数据后，您可以随时检查是否有所需的长度：
$ phone = preg_replace（'/ [^ 0-9] /'，''，$ _POST ['phone']）;
if（strlen（$ phone）=== 10）{
//电话长度为10个字符（###）### - ####
}
您还可以使用PHP的 preg_match 函数，如这个其他的SO问题。
I have very limited experience with PHP and I'm really hoping someone can help me.
What I want to do is sanitize/validate the phone number input so that only numbers are allowed.
I think I need to use FILTER_SANITIZE_NUMBER_INT but I'm not sure where or how to use it.
Here is my code:
<?php
// Replace the email address with the one that should receive the contact form inquiries.
define('TO_EMAIL', '########');
$aErrors = array();
$aResults = array();
/* Functions */
function stripslashes_if_required($sContent) {
if(get_magic_quotes_gpc()) {
return stripslashes($sContent);
} else {
return $sContent;
}
}
function get_current_url_path() {
$sPageUrl = "http://".$_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
$count = strlen(basename($sPageUrl));
$sPagePath = substr($sPageUrl,0, -$count);
return $sPagePath;
}
function output($aErrors = array(), $aResults = array()){ // Output JSON
$bFormSent = empty($aErrors) ? true : false;
$aCombinedData = array(
'bFormSent' => $bFormSent,
'aErrors' => $aErrors,
'aResults' => $aResults
);
header('Content-type: application/json');
echo json_encode($aCombinedData);
exit;
}
// Check supported version of PHP
if (version_compare(PHP_VERSION, '5.2.0', '<')) { // PHP 5.2 is required for the safety filters used in this script
$aErrors[] = 'Unsupported PHP version. <br /><em>Minimum requirement is 5.2.<br />Your version is '. PHP_VERSION .'.</em>';
output($aErrors);
}
if (!empty($_POST)) { // Form posted?
// Get a safe-sanitized version of the posted data
$sFromEmail = filter_input(INPUT_POST, 'email', FILTER_SANITIZE_EMAIL);
$sFromName = filter_input(INPUT_POST, 'name', FILTER_SANITIZE_STRING, FILTER_FLAG_STRIP_LOW);
$sMessage = "Name: ".stripslashes_if_required($_POST['name']);
$sMessage .= "\r\nEmail: ".stripslashes_if_required($_POST['email']);
$sMessage .= "\r\nBusiness: ".stripslashes_if_required($_POST['business']);
$sMessage .= "\r\nAddress: ".stripslashes_if_required($_POST['address']);
$sMessage .= "\r\nPhone: ".stripslashes_if_required($_POST['phone']);
$sMessage .= "\r\nMessage: ".stripslashes_if_required($_POST['message']);
$sMessage .= "\r\n--\r\nEmail sent from ". get_current_url_path();
$sHeaders = "From: '$sFromName' <$sFromEmail>"."\r\n";
$sHeaders .= "Reply-To: '$sFromName' <$sFromEmail>";
if (filter_var($sFromEmail, FILTER_VALIDATE_EMAIL)) { // Valid email format?
$bMailSent = mail(TO_EMAIL, "New inquiry from $sFromName", $sMessage, $sHeaders);
if ($bMailSent) {
$aResults[] = "Message sent, thank you!";
} else {
$aErrors[] = "Message not sent, please try again later.";
}
} else {
$aErrors[] = 'Invalid email address.';
}
} else { // Nothing posted
$aErrors[] = 'Empty data submited.';
}
output($aErrors, $aResults);
解决方案 Have you looked into PHP's preg_replace function? You can strip out any non-numeric character by using preg_replace('/[^0-9]/', '', $_POST['phone']).
Once you filter out the character data, you can always check to see if it is of a desired length:
$phone = preg_replace('/[^0-9]/', '', $_POST['phone']);
if(strlen($phone) === 10) {
//Phone is 10 characters in length (###) ###-####
}
You can also use PHP's preg_match function as discussed in this other SO question.
