使用php表单发送反馈

我想将反馈发送到我的电子邮件地址。我已经编写了以下代码。但当我按下submit时，什么也没发生

<?php
$action=$_REQUEST['action'];
if ($action=="") { 
/* display the contact form */
?>
    <form method="post" action="" enctype="multipart/form-data">
        <input class="inputst" type="text" placeholder="Your Name" name="s_name"><br>
        <input class="inputst" type="email" placeholder="Your Email" name="s_email"><br>
        <input class="inputst" type="text" placeholder="Phone Number" name="s_mobile"><br>
        <input class="inputst" type="text" placeholder="Delivery Address" name="s_address"><br>
        <input class="inputst" name="s_link" type="text" value="http://alutamarket.com/boutique-and-fashion-store/phones-tabs-accessories/samsung-galaxy-note-3_i3" name="productlink"><br>
        <div style="margin-top:20px;"><a type="submit" class="im-contac"><span class="im-top">Send Now</span><span class="im-bot">Send inquiry now</span><i class="fa fa-paper-plane"></i></a></div>
    </form>
<?php
} else {
    /* send the submitted data */
    $name=$_REQUEST['s_name'];
    $email=$_REQUEST['s_email'];
    $mobile=$_REQUEST['s_mobile'];
    $address=$_REQUEST['s_address'];
    $message=$_REQUEST['s_link'];
    if (($name=="")||($email=="")||($mobile=="")||($address=="")||($message=="")) {
        echo "All fields are required, please fill <a href=\"\">the form</a> again.";
    } else {        
        $from="From: $name<$email>\r\nReturn-path: $email";
        $subject="Message sent using your contact form";
        mail("myemail@gmail.com", $subject, $message, $from);
        echo "Email sent!";
    }
}  
?>

再一次。”；
}否则{
$from=“from:$name\r\n返回路径：$email”；
$subject=“使用您的联系方式发送的邮件”；
邮件（“myemail@gmail.com“，$subject，$message，$from）；
回显“已发送电子邮件！”；
}
}  
?>

我还想向发件人发送一份副本电子邮件。

需要更改

1）创建提交到提交表单

2）检查是否设置了“提交”按钮

试试这个

<?php
if(isset($_POST['submit'])) {
    $name=$_POST['s_name'];
    $email=$_POST['s_email'];
    $mobile=$_POST['s_mobile'];
    $address=$_POST['s_address'];
    $message=$_POST['s_link'];
    if (($name=="")||($email=="")||($mobile=="")||($address=="")||($message=="")) {
        echo "All fields are required, please fill <a href=\"\">the form</a> again.";
    } else {       
        $from="From: $name<$email>\r\nReturn-path: $email";
        $subject="Message sent using your contact form";
        mail("myemail@gmail.com", $subject, $message, $from);
        echo "Email sent!";
    }
} 
?>

<?php
$action=$_REQUEST['action'];
if ($action=="") {
    /* display the contact form */
    ?>
    <form method="post" action="" enctype="multipart/form-data">
        <input class="inputst" type="text" placeholder="Your Name" name="s_name"><br>
        <input class="inputst" type="email" placeholder="Your Email" name="s_email"><br>
        <input class="inputst" type="text" placeholder="Phone Number" name="s_mobile"><br>
        <input class="inputst" type="text" placeholder="Delivery Address" name="s_address"><br>
        <input class="inputst" name="s_link" type="text" value="http://alutamarket.com/boutique-and-fashion-store/phones-tabs-accessories/samsung-galaxy-note-3_i3" name="productlink"><br>
        <div style="margin-top:20px;"><button type="submit" name="submit" class="im-contac"><span class="im-top">Send Now</span><span class="im-bot">Send inquiry now</span><i class="fa fa-paper-plane"></i></button></div>
    </form>
<?php 
}
?>
