然後用這個PHP處理它：

    //Validate first

      var_dump($_POST);} 
     else { 


    $email_from = '[email protected]';//<== update the email address 
    $email_subject = "New Registration"; 
    $email_body = "You have received a new registration.\n".

    header("Location: thanks2.htm",303); 
    echo "<meta http-equiv='refresh' content='0; url=thanks2.htm'>"; 
    } 
    ?>

我包括後續代碼var_dump因爲我不斷收到我的「請所有填寫需要的箱子「。錯誤。當我查看轉儲時，沒有沒有價值的字符串。我很困惑，斷開連接在哪裏？

var_dump：

你錯過了，如果下劃線：

if ($_POST['firstname'] == "" ||

的$_POST['shirt size']應該shirt_size。
^

這發生在你身上，因爲你的做法是不優雅，那巨大的If是討厭討厭討厭的xD。你應該看看foreach()學習循環數組。在php文檔中也可以看到empty()和isset() ，這些是你驗證的第一個朋友。

這怎麼做：

Basicly搜索你的錯誤，我複製粘貼你的if語句，以及var_dumped陣列，使用了一些正則表達式魔術上他們，使他們成爲有效的PHP數組：

$arr = array("lastname"=>"test", "firstname"=>"test", "initial"=>"t", "streetaddress"=>"123 test", "addressline2"=>"test", "city"=>"testville", "state"=>"test state", "zip"=>"12345", "email"=>"[email protected]", "youth_area"=>"123", "youth_phone"=>"1234566", "month"=>"21", "day"=>"21", "year"=>"2121", "grade"=>"12", "gender"=>"Male", "guardian_first"=>"test test", "guardian_last"=>"test test", "areacode"=>"123", "cellphone"=>"1231231", "parent_email"=>"[email protected]", "emergency_contact_1"=>"test test", "emergency_contact_1_areacode"=>"123", "emergency_contact_1_phone"=>"1231231", "emergency_contact_2"=>"test testy", "emergency_contact_2_areacode"=>"123", "emergency_contact_2_phone"=>"1232132", "home_church"=>"church test", "church_areacode"=>"321", "church_phone"=>"6548976", "contact_person"=>"tester tests", "special_needs"=>"none. testing", "shirt_size"=>"XL", "roommate"=>"none", "satellite1"=>"drama", "satellite2"=>"photo1", "satellite3"=>"volleyball", "submit"=>"Submit"); 
$arr2 = array('firstname', 'lastname', 'streetaddress', 'city', 'state', 'zip', 'email', 'month', 'day', 'year', 'grade', 'gender', 'guardian_first', 'guardian_last', 'areacode', 'cellphone', 'emergency_contact_1', 'emergency_contact_1_areacode', 'emergency_contact_1_phone', 'emergency_contact_2', 'emergency_contact_2_areacode', 'emergency_contact_2_phone', 'shirt size', 'satellite1', 'satellite2', 'satellite3', 'youth_area', 'youth_phone');

下一次請使用var_export（），所以你輸出一個有效的PHP數組，人們可以只是粘貼它！

然後我用這個循環，以瞭解他們是否匹配：

foreach($arr2 as $k=>$v){ 
    if(!array_key_exists($v, $arr)){ 
     echo "$v not in array 1 <br/>"; 
    } 
}

輸出：恤尺寸不陣列1

享受！

啊，我忘了PHP不會識別這個空間。我回去了，把所有的襯衫尺碼改正爲shirt_size，一切按我的意圖進行。謝謝！ – Chris569x 2013-03-14 16:52:47

不用客氣，php確實可以識別空間，只是空間和下劃線是不同的東西......請記住嘗試一種不同的方法，就像我在答案中展示的那樣，例如，它會爲您節省很多時間檢查那些愚蠢的小東西 – aleation 2013-03-14 16:54:30

<?php 
    if (isset($_POST['submit'])) { 
     $firstname = $_POST['firstname']; 
     $lastname = $_POST['lastname']; 

     if (empty($firstname == '' || $lastname == '')) { 
      echo "empty"; 
     } 
    } 

?>

或者財產以後這樣的：

// Required field names 
$required = array('login', 'password', 'confirm', 'name', 'phone', 'email'); 

// Loop over field names, make sure each one exists and is not empty 
$error = false; 
foreach($required as $field) { 
    if (empty($_POST[$field])) { 
    $error = true; 
    } 
} 

if ($error) { 
    echo "All fields are required."; 
} else { 
    echo "Proceed..."; 
}

請使用

if(empty($_POST['firstname']) && $_POST['firstname'])

代替：

對於每個字段。您的數組非常大，您可能錯過了任何字段，empty（）將檢查它是否已設置&下一條語句將檢查它是否爲非零。 for more about empty()

希望能對您有所幫助！
