PHP引导程序形式重定向错误

Question

我需要你的帮助。我的网站正在使用Bootstrap框架。对于查询产品，我准备了一些html表格。它们的结构如下：

        <form action="../../../scripts/processor.php" method="post" enctype="multipart/form-data" class="form-horizontal" id="form" style="padding-top: 2rem;" accept-charset="UTF-8">
  <div class="form-group">
    <label for="produkt" class="col-sm-3 control-label">Produkt</label>
    <div class="col-sm-9">
      <select class="form-control" name="product" id="product" onChange="checkSelection()">
        <option value="none">Wählen Sie</option>
        <option value="CREAPUR">CREATON Estrichziegel CREAPUR</option>
        <option value="KERATOP">CREATON Estrichziegel KERATOP</option>
      </select>
      <script type="text/javascript">
		  
		  function checkSelection() {
		  if (document.getElementById("product").value === "CREAPUR" ){
			  document.getElementById("farbe-naturrot").disabled=false;
			  document.getElementById("c-naturrot").style.display="inline";
			  document.getElementById("c-anthrazitgrau").style.display="none";
			  document.getElementById("c-altweiß").style.display="none";
			  document.getElementById("c-gelbrot").style.display="none";
		  } else if(document.getElementById("product").value === "KERATOP" ) {
			  document.getElementById("farbe-naturrot").disabled=true;
			  document.getElementById("c-naturrot").style.display="none";
			  document.getElementById("farbe-anthrazitgrau").disabled=false;
			  document.getElementById("c-anthrazitgrau").style.display="inline";
			  document.getElementById("farbe-altweiß").disabled=false;
			  document.getElementById("c-altweiß").style.display="inline";
			  document.getElementById("farbe-gelbrot").disabled=false;
			  document.getElementById("c-gelbrot").style.display="inline";
		  } else{
			  window.alert("Wählen Sie eine Farbe für eine Anfrage");
		  }
		}
		  
		  
		  

		</script>

从我的角度来看，一切看起来都很好。我的php脚本如下所示：

<?php 
$errors = '';
$myemail = 'maier@thermisto.com';//<-----Put Your email address here.


$product = $_POST['product'];
$colour = $_POST['colour'];
$Waermeerzeuger = $_POST['Waermeerzeuger'];
$Flaechenformat = $_POST['Flaechenformat'];
$bodenbelaege = $_POST['bodenbelaege'];
$fliesenformat = $_POST['fliesenformat'];
$montageoffer = $_POST['montage'];
$Estrich = $_POST['Estrich'];
$max_Aufbau = $_POST['max_Aufbau'];
$company = $_POST['company'];
$tax_id = $_POST['tax_id'];
$gender = $_POST['gender'];

$given_name = $_POST['given_name'];
$family_name = $_POST['family_name'];
$adress = $_POST['adress'];
$zip = $_POST['zip'];
$city = $_POST['city'];
$land = $_POST['land'];
$email_address = $_POST['email']; 
$telephone = $_POST['telephone'];




if (!preg_match("/^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$/i", $email_address))
{
$errors .= "\n Error: Invalid email address";
}

if(isset($_POST['submit'])){
	$headers = "From: No-Reply@thermisto.com \n"; 
$headers .= "Reply-To: $email_address";
$to = $myemail; 
$email_subject = "Inquiry form submission: $family_name, $given_name";
$email_body = "You have received a request for an offer. ".

其他信息可能是我使用的是SSL网站。我已经google了很多，并检查了SO。

每次我提交按钮时，我都会收到301“太可能重定向”

解决方案的提示非常好。

更新：我添加了完整的代码
