我试图用php建立一个盲输入字段，它将检查并确保输入字段为空，如果它不是空的，它将不会发送它设置为发送的消息但我遇到了这里放置和措辞的几个问题是我的代码任何输入将非常感激。
<?php
// Set email variables
$email_to = 'email@example.com';
$email_subject = 'Website Message';
// Set required fields
$required_fields = array('fullname','email','comment');
$fakes = array('Email1');
// set error messages
$error_messages = array(
'fullname' => 'Please enter a Name to proceed.',
'email' => 'Please enter a valid Email Address to continue.',
'comment' => 'Please enter your Message to continue.'
);
// Set form status
$form_complete = FALSE;
// configure validation array
$validation = array();
// check form submittal
if(!empty($_POST)) {
// Sanitise POST array
foreach($_POST as $key => $value) $_POST[$key] = remove_email_injection(trim($value));
foreach($fakes as $fake)
if($fake == 'Email1') if(!check_for_content($_POST[$fake])) die;
else {
// Loop into required fields and make sure they match our needs
foreach($required_fields as $field) {
// the field has been submitted?
if(!array_key_exists($field, $_POST)) array_push($validation, $field);
// check there is information in the field?
if($_POST[$field] == '') array_push($validation, $field);
// validate the email address supplied
if($field == 'email') if(!validate_email_address($_POST[$field])) array_push($validation, $field);
}
// basic validation result
if(count($validation) == 0) {
// Prepare our content string
$email_content = 'New Website Comment: ' . "\n\n";
// simple email content
foreach($_POST as $key => $value) {
if($key != 'submit') $email_content .= $key . ': ' . $value . "\n";
}
// if validation passed ok then send the email
mail($email_to, $email_subject, $email_content);
// Update form switch
$form_complete = TRUE;
}
}
}
function validate_email_address($email = FALSE) {
return (preg_match('/^[^@\s]+@([-a-z0-9]+\.)+[a-z]{2,}$/i', $email))? TRUE : FALSE;
}
function remove_email_injection($field = FALSE) {
return (str_ireplace(array("\r", "\n", "%0a", "%0d", "Content-Type:", "bcc:","to:","cc:"), '', $field));
}
function check_for_content($fake = FALSE) {
return (preg_match('[A-Z0-9._%+-]', $Email1))? TRUE : FALSE;

答案 0 :(得分：0)
您的代码中有很多错误会导致无法获得正确的结果
<input type="text" id="Email1" class="detail" name="Emial1" />
注意，name="Emial1"，但在PHP代码中检查'Email1'。纠正其中一个。
下一篇：
function check_for_content($fake = FALSE) {
return (preg_match('[A-Z0-9._%+-]', $Email1))? TRUE : FALSE;
}
使用$ Email1变量就不合适了。正则表达式缺乏边界。至少它应该是
function check_for_content($fake = FALSE) {
return (preg_match('/[A-Z0-9._%+-]/i', $fake))? TRUE : FALSE;
}
当您调用此函数时，为什么不条件？
if($fake == 'Email1') if(!check_for_content($_POST[$fake])) die();
我认为反之亦然。
无论如何，我个人只是使用这样的东西：
foreach($fakes as $fake)
if(!empty($_POST[$fake])) { die();}
// dont need 'else'
此外，在调试您的PHP代码时，请确保您打开错误，它确实有帮助
error_reporting(0);
ini_set('display_errors', 0);
