單選按鈕：PHP只有通過「其他」價值

Question

我已經借了（在這裏和其他網站）PHP的幾個版本的選定量的無線電字段集傳遞到電子商務門戶，但不管是什麼我都試過了，它只會通過輸入到我的「其他」字段（這是一個簡單的文本框）的金額。選中任何一個單選按鈕後，出現一個錯誤信息，指出該字段丟失或格式錯誤。這是我第一次使用PHP，因此非常感謝在一年級提供的任何幫助！雖然這個問題似乎與if語句相關，但我包含了整個PHP，因爲我不太瞭解PHP的工作方式。謝謝。

<?php 
$x_login = "HCO-ST.-T-902"; // Hosted Payment Page ID. 
$transaction_key = "6~~xpvR~xMJXN_RkCc99"; // 

if(isset($_POST['amount'])) { 
    if($_POST['amount'] == '5') { 
     $x_amount = "5.00"; 
    } elseif($_POST['amount'] == '10') { 
     $x_amount = "10.00"; 
    } elseif($_POST['amount'] == '25') { 
     $x_amount = "25.00"; 
    } elseif($_POST['amount'] == '50') { 
     $x_amount = "50.00"; 
    } elseif($_POST['amount'] == '100') { 
     $x_amount = "100.00"; 
    } elseif($_POST['amount'] == '200') { 
     $x_amount = "200.00"; 
    } elseif($_POST['amount'] == 'other') { 
     $x_amount = $_POST['amount']; 
    } 
} 

$x_invoice_num = $_POST['invoice']; 
$x_first_name = $_POST['x_first_name']; 
$x_email = $_POST['x_email']; 
$CardHoldersName= $_POST['CardHoldersName']; 
$x_currency_code = "USD"; // Needs to agree with the currency of the payment page 
srand(time()); // initialize random generator for x_fp_sequence 
$x_fp_sequence = rand(1000, 100000) + 123456; 
$x_fp_timestamp = time(); // needs to be in UTC. Make sure webserver produces UTC 

// The values that contribute to x_fp_hash 
$hmac_data = $x_login . "^" . $x_fp_sequence . "^" . $x_fp_timestamp . "^" . $x_amount . "^" . $x_currency_code; 
$x_fp_hash = hash_hmac('MD5', $hmac_data, $transaction_key); 

echo ('<input type="hidden" name="x_login" value="' . $x_login . '">'); 
echo ('<input type="hidden" name="x_amount" value="' . $x_amount . '">'); 
echo ('<input type="hidden" name="x_fp_sequence" value="' . $x_fp_sequence . '">');

HTML

<fieldset name="amount"> 
<legend><h3>Amount**</h3></legend> 
<hr class="hr"> 
<p style="margin:0"> 
<input name="amount" type="radio" value="5" checked="checked"> $5.00 
<input name="amount" type="radio" value="10"> $10.00 
<input name="amount" type="radio" value="25"> $25.00<br> 
<input name="amount" type="radio" value="50"> $50.00 
<input name="amount" type="radio" value="100"> $100.00 
<input name="amount" type="radio" value="200"> $200.00 
</p> 
<input name="amount" type="radio" value="other"><span style="text-decoration: underline">Other Amount: </span> 
<input name="amount" type="text" style="width:100%"> 
</fieldset> 

Answer 1

看你的HTML代碼：

<fieldset name="amount"> 
<legend><h3>Amount**</h3></legend> 
<hr class="hr"> 
<p style="margin:0"> 
<input name="amount" type="radio" value="5" checked="checked"> $5.00 
<input name="amount" type="radio" value="10"> $10.00 
<input name="amount" type="radio" value="25"> $25.00<br> 
<input name="amount" type="radio" value="50"> $50.00 
<input name="amount" type="radio" value="100"> $100.00 
<input name="amount" type="radio" value="200"> $200.00 
</p> 
<input name="amount" type="radio" value="other"><span style="text-decoration: underline">Other Amount: </span> 
<input name="amount" type="text" style="width:100%"> 
</fieldset> 

末具有相同的名稱（金額）爲以前的HTML元素總是使用，在這種情況下，它是文本類型。 （它「覆蓋」了以前的單選按鈕）

如果更改文本字段的名稱，則會在提交表單時獲取所選射頻按鈕的值。

嘗試類似：

<fieldset name="amount"> 
<legend><h3>Amount**</h3></legend> 
<hr class="hr"> 
<p style="margin:0"> 
<input name="amount" type="radio" value="5" checked="checked"> $5.00 
<input name="amount" type="radio" value="10"> $10.00 
<input name="amount" type="radio" value="25"> $25.00<br> 
<input name="amount" type="radio" value="50"> $50.00 
<input name="amount" type="radio" value="100"> $100.00 
<input name="amount" type="radio" value="200"> $200.00 
</p> 
<input name="amount" type="radio" value="other"><span style="text-decoration: underline">Other Amount: </span> 
<input name="otherAmount" type="text" style="width:100%"> 
</fieldset> 

Answer 2

更改您的最後一個文本字段名。這個名字不應該和廣播名稱相同。
