私はPHPの経験が非常に限られているため、誰かが私を助けてくれることを本当に望んでいます.
私がやりたいのは、電話番号の入力をサニタイズ/検証して、番号のみが許可されるようにすることです。
使用する必要があると思いますFILTER_SANITIZE_NUMBER_INT
が、どこでどのように使用するのかわかりません。
これが私のコードです:
<?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);
