PHP がフォーム データを読み取るために必要なことがいくつかあります。まず、Waygood が提案したように、$_POST 値を変更して、渡された変数名を一重引用符で囲むことをお勧めします。

//For example:
$_POST[address]; 

// Should change to:
$_POST['address']; //Notice the single quotes around the word address

次に、ジョンが答えたように、渡された送信された値への参照はhtml フォームにありません。最初のステートメントを作成するために、値 1 を保持する非表示の入力をフォーム (タグ間の任意の場所) に追加する必要があります。残りの php コードを実行するには true にします。

<!-- Put this input tag anywhere between your opening and closing form tags in your html -->
<form method="POST" action="your_submission_page.php">
    <input type="hidden" name="submitted" value="1" />
</form>

最後に、フォームのすべてのエラーをユーザーに通知して、フォームを送信する前にエラーが発生しないようにすることをお勧めします。あなたがしなければならないことは、エラーメッセージの動的配列を構築し、エラーがあるかどうかを確認してから、それらをすべて表示することです.

<?php
    // Create a dynamic array for the error messages and validate everything before sending them back to the form that shows them

    // Here is a sample of your code with the dynamic array built in
    $error_msgs = array ();   
    $error = 0; //Error flag     

    if ($_POST['cwage2']){
        $cwage2 = $_POST['cwage2'];
    } else {
        $error_msgs[] = "Please enter wage earned, or type N/A";
        $errors++; //Flag to let the code know that there are errors, used in every case
    }

    if ($_POST['cstart2']){
        $cstart2 = $_POST['cstart2'];
    } else {
        $error_msgs[] = "Please enter date started, or type N/A";
        $errors++; //Flag to let the code know that there are errors, used in every case
    }

    // Finally at the end, check to see if there are any errors and display them all
    if ($errors > 0) {
        //Display the amount of errors first
        echo "There were " . $errors . " errors in your submission, please correct them.<br/>";

        //Then display your error array
        foreach ($error_msgs as &$msg) {                
            echo $msg . "<br/>"; 
        }
    } else {
        // Add code here to submit the form however you'd like

    }

?>

名前の付いたフォームフィールドが表示されません。フォームフィールドがsubmittedないと、PHP検証コードはトリガーされません。変更してみてください：

if ($_POST['submitted']==1) {

このようなより一般的なものに：

if ('POST' === $_SERVER['REQUEST_METHOD']) {

OK @キバハイトフィールド

配列要素への参照を次のように変更します。

$_POST[first_name]

に：

$_POST['first_name']

  1. if はありません

    else{ if ($errormsg){ //既にエラーがある場合は、次のエラーを追加 $errormsg = $errormsg; }そうしないと{

    }

    }

  2. $errormsg = $errormsg; 何の意味もありません。

  3. Errormsg が割り当てられますが、使用されることはありません。echo $errormsg; を使用します。
  4. $_POST[first_name] は $_POST['first_name'] にする必要があります
  5. $_POST['submitted'] の代わりに if($_POST['field89'] == 'Submit') を使用します
  6. 小さなフォームで試してみて、機能し始めたら拡張してみてはいかがでしょうか。

または、この方法で簡単に確認できます

if($_POST){
 //form is posted do your work here
}

フォーム（「GET」、「POST」）のメソッドを指定しましたか？

エラーを表示する方法がないようです。これを php コードの最後に追加してみてください:

echo $errormsg; die();

それ以外の

$errormsg = $errormsg;

何が起こるか教えてください。
