php mail（）驗證問題。 不顯示警報，而是打開php表單

[英]php mail() validation problems. Does not show alert, it opens the php form instead

問題描述

我對php很陌生，需要幫助。 我已經開發了一個php聯系人頁面，但是當字段為空白時，我在驗證方面遇到問題。 當我測試我的驗證時，它會打開php頁面並顯示消息，而不是顯示警報。請參見下面的圖片

這是我的代碼：

驗證任何空白字段的最簡單方法是在輸入HTML中添加required ，如下所示。 

<form method="post" class="submitphoto_form" action="contact.php" id="contactpage">
    <input type="text" class="form-control wpcf7-text" placeholder="Your name" name="name" id="name" required>
    <input type="email" class="form-control wpcf7-email" placeholder="Email address" name="email" id="email" required>
    <input type="text" class="form-control wpcf7-text" placeholder="Subject" name="subject" id="subject" required>
    <textarea style="height:300px" class="form-control wpcf7-text" placeholder="What would you like to tell us" name="message" id="message" required></textarea>
    <input type="submit" value="Submit" class="wpcf7-submit photo-submit" name="send" id="send">
</form>

另請注意，您輸入的電子郵件類型應為“電子郵件”，而不是“郵件”。

使用PHP驗證的缺點是用戶將不得不重新輸入所有字段。

使用JS驗證的缺點是，如果用戶禁用了JS，則驗證將無法進行。

使用簡單的HTML驗證的好處是，它將在所有瀏覽器上都可以工作，並且在任何空白字段和​​/或無效的電子郵件格式的情況下將停止提交表單。

使用這種方法，您不需要使用JS進行驗證。 它是純HTML。

希望這可以幫助。
