PHP聯系表單不適用於FF，但適用於Edge IE chrome和safari

Question

親愛的人們，以下代碼可以在IE（最新），Edge，Chrome和Safari中完美執行，但在FF中超時，並且在firefox中顯示表單也存在問題。

在Firefox中，一旦我按Submit，它就會開始運行sendform.php，它會正確執行， 但是一旦一切正確填寫 ， 它就會卡住，它應該向我發送表單/電子郵件 。

該頁面也在使用中。 感謝提供更好/更安全代碼的技巧。

來自代碼的聯系人（如kontakt.php中所示）：

<?php
session_start();

$success='';
if($_SESSION['sent'] == '1')
{
    $success='<div class="container">
                <h3>Vielen Dank. Ihre Nachricht wurde übermittelt.</h3>
            </div>';

    $css='<style type="text/css">#phpcontactform{display:none;}</style>';

    unset($_SESSION['sent']);
}

?>

老實說，我不知道是什么原因引起的，可能是我懷疑它只是我的Firefox。 預先加油和謝謝。

Answer 1

我的猜測是有錯誤，並且Firefox沒有發送引薦來源網址，因此重定向從未發送。

您能否發送任何轉換為UTF-8或進行其他處理時可能會意外少於3個字符的文本？

能夠看到$err的內容將有助於縮小范圍或排除這種可能性。
