这会正常工作吗？第一次完全从头开始做某事，哈哈！
还行！我已经改变了它。这个呢？我也应该做空的事情吗？
<?php
if (!isset($_POST['ign'], $_POST['email'])) {
if($_POST['ign'] && $_POST['email']){
echo "Please fill out all of the fields!";
die;
}
if(var_filter($_POST['email'], FILTER_VALIDATE_EMAIL))
$email = $_POST['email'];
echo ("Thanks, " . htmlentities($_POST['ign']) . ", you will recieve an email when the site is complete!");
}
else {
echo "Your email was invalid!";
}
// insert email and ign into database
?>
使用内置函数，不要重新发明轮子：
if(filter_var($mail, FILTER_VALIDATE_EMAIL)){
echo "Mail is valid!";
}
为什么你的函数名称全部大写？
。你看出这之间的区别了吗...
if(func($_POST['email'] == TRUE)){
而这个..
if(func($_POST['email']) == TRUE){
？
那里有很多错误。以下是您应该做的：
// First check if both fields are present. Usually there is no point in doing this
// because the next check will also catch this case, but you had it so I put it in too.
if (!isset($_POST['ign'], $_POST['email'])) {
echo ("Error in form data!");
die; // or something else
}
// Then check if both values are non-"empty" (you might want to look at the docs for
// an explanation of what this means exactly).
if (empty($_POST['ign']) || empty($_POST['email'])) {
echo ("Please enter all of the values!");
die; // or something else
}
// Finally, validate the email. DO NOT COMPARE WITH true!
if (!filter_var($_POST['email'], FILTER_VALIDATE_EMAIL)) {
echo "Failure!";
die; // etc
}
echo ("Thanks, " . htmlentities($_POST['ign']) . ", blah blah!");
