使用php，ajax和javascript計算訂單的結果，複選框不起作用

2017-05-25 33 views

我剛剛創建了一個很好的工具來計算結果（通過電子郵件添加，乘以和發送總數）爲通用麪包店。使用php，ajax和javascript計算訂單的結果，複選框不起作用

我的問題是，我無法獲得我的複選框輸入內的值。我嘗試了幾種方法，但是我能從無線電覆選框中獲得的唯一價值是1（我認爲這個值非常「真實」）。其他一切正在工作，但我仍然覺得它有點冗長。

這裏是我的代碼：

的HTML（問題）：

<fieldset> 
         <label>MEAT & CHEESE TRAYS</label><br> 
         <label>Executive Tray</label><br> 
         <label class='radiolabel'><input type="checkbox" name="Executive[]" value="45">Serves 10–15 people</label><br/> 
         <label class='radiolabel'><input type="checkbox" name="Executive[]" value="62">Serves 20–25 people</label><br/> 
         <label>Hospitality Tray</label><br> 
         <label class='radiolabel'><input type="checkbox" name="Hospitality[]" value="48">Serves 10–15 people</label><br/> 
         <label class='radiolabel'><input type="checkbox" name="Hospitality[]" value="65">Serves 20–25 people</label><br/> 
         <label>Meat & Cheese Nibbler</label><br> 
         <label class='radiolabel'><input type="checkbox" name="Nibbler[]" value="48">Serves 10–15 people</label><br/> 
         <label class='radiolabel'><input type="checkbox" name="Nibbler[]" value="65">Serves 20–25 people</label><br/> 
         <label>Sliced Cheese Tray</label><br> 
         <label class='radiolabel'><input type="checkbox" name="Sliced[]" value="48">Serves 10–15 people</label><br/> 
         <label class='radiolabel'><input type="checkbox" name="Sliced[]" value="65">Serves 20–25 people</label><br/> 
         <label>Cheese Nibbler</label><br> 
         <label class='radiolabel'><input type="checkbox" name="Cheese[]" value="48">Serves 10–15 people</label><br/> 
         <label class='radiolabel'><input type="checkbox" name="Cheese[]" value="65">Serves 20–25 people</label><br/> 
        </fieldset>

PHP的（問題）：

$value = implode(',', $_POST['Executive']); 
$Body = ""; 
$Body .= "Here's the order from: "; 

$Body .= "Executive Tray: "; 
$Body .= $value; 
$Body .= print_r($value); 
$Body .= "\n"; 
$Body .= "Hospitality Tray: "; 
$success = mail($EmailTo, $Subject, $Body, "From:".$email);

在JavaScript submitForm()功能不包括提交 「行政」， 「好客」， 「衝剪」 的，「刨切「或」奶酪「字段。

在您的數據串，它們不存在...

data: "firstname=" + firstname + "&email=" + email + "&company=" + company + "&phonenumber=" + phonenumber + "&address=" + address + "&small=" + small + "&large=" + large + "&delights=" + delights + "&bagel=" + bagel + "&spinach=" + spinach + "&party=" + party + "&sweet=" + sweet + "&soft=" + soft + "&chocolate=" + chocolate + "&white=" + white + "&pickle=" + pickle,

這意味着這些領域都從未提交給PHP表單處理程序，所以這就是爲什麼你不能從他們那裏得到任何東西。

並非每次輸入自己賦值給一個變量，然後起草數據串的複雜和冗長的方法，爲什麼不嘗試一個更簡單，更面向未來的方法，如...

var datastring = $("#calculatoform").serialize(); 
    $.ajax({ 
     type: "POST", 
     url: "submitform.php", 
     data: datastring, 
     success : function(text){ 
      if (text == "success"){ 
       formSuccess(); 
      } else { 
       formError(); 
      } 
     } 
    });

太棒了！接得好！ – Matto

我會嘗試一下序列化方法。我是否必須與網址結合使用，還是隻需要發送數據？ – Matto

有什麼類似的PHP來獲得一堆價值？ – Matto

錯誤應該在你的PHP裏面。

對於以布爾值爲值的複選框值，如果使用該類型的檢查，那麼當複選框爲false時，您將無法進入if內部。

嘗試從這個改變你的複選框檢查：

if (empty($_POST["checkboxName"])) { 
    $errorMSG .= "Message is required "; 
} else { 
    $checkboxName = $_POST["checkboxName"]; 
}

這樣：

if (isset($_POST["checkboxName"])) { 
    $errorMSG .= "Message is required "; 
} else { 
    $checkboxName = $_POST["checkboxName"]; 
}

或許你您的問題解決。

p.s.空從PHP官方文檔這裏DOC：

Determine whether a variable is considered to be empty. A variable is considered empty if it does not exist or if its value equals FALSE.

對於特定價值我只使用 ：$ value = implode（'，'，$ _POST ['Executive']）; 我使用其他方法的所有其他值（驗證名稱，等等） – Matto

+0

是$ _POST ['執行']複選框的值？還是他們都是價值觀？ – quirimmo

+1

似乎在JavaScript中的發佈數據中沒有一個名爲「Executive」的參數，您確定要發送它嗎？並且是複選框的所有值還是隻有一個？ – quirimmo
