我有一個自我張貼文件，有表單字段填寫與php處理相同的文件。我的問題是，打開網頁（網站）時，消息「消息已發送！」在表格可以填寫信息之前立即顯示。 PHP郵件（）函數鏈接到我的電子郵件帳戶，所以我收到表格數據電子郵件。但是沒有數據發送，因爲電子郵件是在填寫表格之前發送的。我希望能夠在發送電子郵件之前填寫表格，以便表單發送實際信息。我研究過這個話題，並沒有提出任何建議。任何幫助都是極好的！這裏是我的代碼...PHP郵件（）發送郵件之前填寫表格
<?php
foreach($_POST as $key => $value) //This will loop through each name-value in the $_POST array
{
$tableBody .= "<tr>"; //formats beginning of the row
$tableBody .= "<td>$key</td>"; //dsiplay the name of the name-value pair from the form
$tableBody .= "<td>$value</td>"; //dispaly the value of the name-value pair from the form
$tableBody .= "</tr>"; //End this row
}
echo "<table border='1'>";
echo "<tr><th>Field Name</th><th>Value of field</th></tr>";
foreach($_POST as $key => $value)
{
echo '<tr class=colorRow>';
echo '<td>',$key,'</td>';
echo '<td>',$value,'</td>';
