我试图用 PHP 在 WHMCS 上创建一个登录页面。我的代码是这样的：
<div class="clearfix"></div>
<div class="header_medium two">
<div class="container">
<h3 class="bigtext"> We are <span>Foxuhost.</span></h3>
<h3 class="smalltext"><span>Get 7+</span> Unique Layouts</h3>
</div>
</div>
<!--end header medium-->
<div class="section_holder18">
<div class="container">
<div class="pagetitle">
<h3>Login form</h3>
</div>
<div class="pagenation"> <a href="index.html">Home</a> <i>/</i> <a href="#">Pages</a> <i>/</i> Login form</div>
</div>
</div>
<!--end pagenation-->
<div class="clearfix"></div>
<div class="section_holder27" name="l1">
<div class="container" name="l2">
<div class="login_form" name="l3">
<form method="post" id="sky-form" class="sky-form" name="l4">
<header>Login form</header>
<fieldset name="l5">
<section name="l6">
<div class="row" name="l7">
<label class="label col col-4">E-mail</label>
<div class="col col-8"name="l8">
<label class="input" name="l9">
<i class="icon-append icon-user"></i>
<input type="email" name="emailer">
</label>
</div>
</div>
</section>
<section>
<div class="row">
<label class="label col col-4">Password</label>
<div class="col col-8">
<label class="input">
<i class="icon-append icon-lock"></i>
<input type="password" name="password6">
</label>
<div class="note"><a href="#sky-form2" class="modal-opener">Forgot password?</a></div>
</div>
</div>
</section>
<section>
<div class="row">
<div class="col col-4"></div>
<div class="col col-8">
<label class="checkbox"><input type="checkbox" name="remember" checked><i></i>Keep me logged in</label>
</div>
</div>
</section>
</fieldset>
<footer>
<div class="fright">
<a href="http://trixia.dk/templates/d/register.html" class="button button-secondary eight">Register</a>
<button type="submit" name="send" value="send" class="button eight">Log in</button>

</div>
<form action="http://trixia.dk/templates/d/demo-recovery.php" id="sky-form2" class="sky-form sky-form-modal">

<fieldset>
<section>
<label class="label">E-mail</label>
<label class="input">
<i class="icon-append icon-user"></i>
<input type="email" name="email" id="email">
</label>
</section>
</fieldset>
<footer>
<button type="submit" name="submit" class="button">Submit</button>
<a href="#" class="button button-secondary modal-closer">Close</a>
</footer>
<div class="message">
<i class="icon-ok"></i>
<p>Your request successfully sent!<br><a href="#" class="modal-closer">Close window</a></p>
</div>
</form>
{if $_post["emailer"] != ""}
<div class="error-box alert"> <span><i class="fa fa-exclamation-triangle"></i> Error – message will goes here</span> <a class="mboxes_close" href="#"><i class="fa fa-times"></i></a> </div><!--end item-->
{else}
<h1>asdasd</h1>
{/if}
</div>
</div>
<!--end section 22-->
{literal}
<script type="text/javascript">
function validerform125() {
var email = document.getElementsByName("password6")[0].value;
var password = document.getElementsByName("emailer")[0].value;
if (email == "" && password == "") {
alert("Du skal udfylde alle felter");
}
else if (email == "") {
alert("Du har ikke skrevet noget email");
return false;
}else if (password == "") {
alert("Du har ikke skrevet noget password");
return false;
}else if(email != $values["email"]) {
alert("Dit brugernavn er ikke rigtigt");
return false;
}else if() {
}
else{
alert("Der skete noget");
return false;
}
}
</script>
{/literal}
if 语句有点过了<!--end section 22-->
我在一个较小的网站上尝试过，效果很好。
<!DOCTYPE html>
<html>
<head lang="en">
<meta charset="UTF-8">
<title></title>
</head>
<body>
<form method="post">
<div>
Navn <input name="navn" type="text"><br/>
Email <input name="email" type="email"><br/>
</div>
<div>
<input type="submit" name="send" value="send">
</div>
</form>
<?php
if ($_POST["navn"] == "") {
echo "hejsa";
return;
}else{
echo "hejsa2";
}
?>
</body>
</html>
错误是当我按下登录按钮时，它不会执行 if 语句。但是当我加载网站时，它会打印出“else”语句。
