在js验证后用php提交表单

Question

我想在使用JavaScript验证后将我的表单提交给一个名为regier.php的PHP文件。HTML表单如下:

HTML表单:

<form onsubmit="return validateForm()" action="register.php" method="post" class="sign-up-form">
<div class="input-field">
<input type="text" placeholder="Nome" name="username" id="username" onkeyup="validateName()"
<span id="name-error"></span>
</div>
<div class="input-field">
<input name="password" type="password" placeholder="Password" id="password"      onkeyup="validatePassw()" />
<span id="passw-error"></span>
</div>
<input onclick="return validateForm()" type="submit" class="btn" value="Registrati">

JAVASCRIPT验证:以下是JavaScript验证代码:

function validateForm() {
if (!validateName()) {
validateName()
}
if (!validateEmail()) {
validateEmail()
}
if (!validatePassw()) {
validatePassw()
}
}```

将action属性设置为文件/代码以验证表单:

<form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>">
