Php 当表单提交的项目的类别发生更改时，在foreach循环中添加标题

我收集具有包含字符串“object_id”和User_id（int）的字段名的POST变量。 我从字段名中提取用户ID

在foreach循环中，每当$object\u ds['transaction\u type']更改值时，我都需要生成标题。 但仅在循环中第一次出现之前

我设法在第一行实现了这一点，但我不知道如何在$n>1的情况下解决它

有小费吗？塔克斯

  $addonFields = array_intersect_key($_POST, array_flip(preg_grep('/object_id/', array_keys($_POST))));
echo "Anzahl User: ".count($addonFields)."<br>";


$mail_subj_customer = "New! Business Opportunities Pharma & Healthcare";

foreach ($addonFields AS $item=>$value){
echo "Number of Objects: ".count($value)."<br>";


$user_id = preg_replace('/[^0-9]/', '', $item);  // Extract User ID from $item

$user_ds = holeDS( 'pmcts_users', 'id', $user_id ); // get DataRow from pmcts_users where id=$user_id



$n=0;
foreach ($value AS $values){
$n++;
$object_ds = holeDS( 'pmcts_unternehmen_produkte', 'object_id', $values ); // get Product DataRow
if ($n==1 && $object_ds['transaction_type']=="Company Sale" ){
$current_trans_type = "Company Sale";
echo "<h2>I. Business Opportunities -Company Sales</h2>";
}
if ($n==1 && $object_ds['transaction_type'] == "Asset Sale"){
$current_trans_type = "Asset Sale";
echo "<h2>II. Business Opportunities - Asset Sales</h2>";
}
if ($n==1 && $object_ds['transaction_type'] == "Licensing Opportunity"){
$current_trans_type = "Licensing Opportunity";
echo "<h2>II. Business Opportunities - Licensing</h2>";
}
echo print_r($values)." - $user_ds[email] - $object_ds[transaction_type]<br>";

}
} 

$addonfelds=array\u intersect\u key（$\u POST，array\u flip（preg\u grep（'/object\u id/'，array\u key（$\u POST）））；
echo“Anzahl用户：”.count（$addonFields）。“
”；
$mail_subc_customer=“新！商机制药与医疗”；
foreach（$addonFields作为$item=>$value）{
回显“对象数：”.count（$value）。“
”；
$user\u id=preg\u replace（“/[^0-9]/”，“$item）；//从$item中提取用户id
$user\u ds=holeDS（'pmcts\u users'，'id'，$user\u id）；//从pmcts\u用户获取数据行，其中id=$user\u id
$n=0；
foreach（$value作为$value）{
$n++；
$object\u ds=holeDS（'pmcts\u unternehmen\u produkte'，'object\u id'，$values）；//获取产品数据行
如果（$n==1&&$object\u ds['transaction\u type']==“公司销售”）{
$current\u trans\u type=“公司销售”；
回声“一、商机——公司销售”；
}
如果（$n==1&&$object\u ds['transaction\u type']==“资产销售”）{
$current\u trans\u type=“资产销售”；
echo“二、商机——资产销售”；
}
如果（$n==1&&$object\u ds['transaction\u type']==“许可机会”）{
$current\u trans\u type=“许可机会”；
echo“二、商业机会-许可证”；
}
echo print_r（$values）。“-$user_ds[email]-$object_ds[transaction_type]
”；
}
} 

它为每个用户生成这样的对象列表输出
用户号码：8
对象编号：7
一、商机——公司销售
22891 - user@customer.com-公司销售
20071 - user@customer.com-公司销售
24591 - user@customer.com-公司销售
（但这里需要另一个标题“资产销售”）
24531 - user@customer.com-资产出售
20491 - user@customer.com-资产出售
（但这里需要另一个标题“许可证”）
24621 - user@customer.com-发牌机会
24651 - user@customer.com-发牌机会

首先考虑填充数组，然后再遍历它。比如：

$headlines = array(
        "Company Sale" => "I. Business Opportunities -Company Sales",
        "Asset Sale" => "II. Business Opportunities - Asset Sales",
        "Licensing Opportunity" => "II. Business Opportunities - Licensing" 
);

$allData = array();
foreach ($addonFields AS $item=>$value){
  $user_id = preg_replace('/[^0-9]/', '', $item);  // Extract User ID from $item
  $user_ds = holeDS( 'pmcts_users', 'id', $user_id ); // get DataRow from pmcts_users where id=$user_id
  foreach ($value AS $values){
     $object_ds = holeDS( 'pmcts_unternehmen_produkte', 'object_id', $values ); 
     if (!isset($allData[$object_ds['transaction_type']])) {
        $allData[$object_ds['transaction_type']] = array();
     }
     $allData[$object_ds['transaction_type']][] = print_r($values, 1)." - $user_ds[email] ;
  }
}

然后显示：

foreach ($allData as $transaction_type => $users) {
  echo "<h2>" . $headlines[$transaction_type] . "</h2>";
  foreach ($users as $user) {
    echo "<div>" . $user . " - " . $transaction_type . "</div>";
  }
}

foreach（$allData作为$transaction\u type=>$users）{
回显“$headlines[$transaction_type]”；
foreach（$users作为$user）{
回显“$user.”-“$transaction_type.”；
}
}

我获得了每个用户的标题列表，如下所示：

     $addonFields = array_intersect_key($_POST, array_flip(preg_grep('/object_id/', array_keys($_POST))));
    echo "Anzahl User: ".count($addonFields)."<br>";

            "Licensing Opportunity" => "III. Business Opportunities - Licensing" 
    );
    
    foreach ($addonFields AS $item=>$value){
    echo "Number of Objects: ".count($value)."<br>";
    
    $count_objects = count($value);
    
    
    $user_id = preg_replace('/[^0-9]/', '', $item);  // Extract User ID from $item

也许这对有同样问题的人有帮助。

谢谢Kinglish，这很好用。谢谢Kinglish，这很好用。但是，它会循环遍历所有用户和对象，并添加标题。我需要改变什么才能循环浏览所有用户和对象，并按每个用户添加标题。例如：“I.商业机会-公司销售23456-user1@company1.com-公司销售23458-user1@company1.com-公司销售二。商业机会-资产出售23456-user1@company1.com-资产出售23458-user1@company1.com-资产出售二。商业机会-许可23452-user1@company1.com-执照持有人```
