HTML 表單在提交時發布 PHP 文件而不是發送電子郵件
[英]HTML form post PHP file on submission rather than sending an email
問題描述
以下是表單的 HTML 代碼，此外它是用於將數據接收到所需電子郵件地址的 php 代碼。 提交時，它會重定向到 php 代碼，而不是發送郵件。 提前致謝。

使用 ajax 和e.preventDefault();發布您的表單e.preventDefault(); 將避免重定向。 我認為這對於評論來說太長了，但我指的是你的評論。
你只是忘了給表單一個 id 外觀在你的代碼中改變這個：
JavaScript：
$("#htmlform").submit(function (e) {....
PHP：
<form name="htmlform" id="htmlform"....
您必須在下面的示例中更改它：
var url = "path/to/your/html_form_send.php";// insert your path to the php file
這是一個工作示例：
<script src="https://code.jquery.com/jquery-1.11.3.min.js"></script>
<script>
$(document).ready(function () {
$("#htmlform").submit(function (e) {
var url = "path/to/your/html_form_send.php"; // the script where you handle the form input.
$.ajax({type: "POST", url: url, data: $(this).serialize(), // serializes the form's elements.
success: function (data) {
alert(data); // show response from the php script.
}});
e.preventDefault(); // avoid to execute the actual submit of the form
});
});
</script>
<form name="htmlform" id="htmlform" method="post" action="html_form_send.php">
<table width="450px">
<!-- just removed for testing -->
<tr>
<td colspan="2" style="text-align:center">
<input type="submit" name="Submit" value="Submit">
</td>
</tr>
</table>
</form>
html_form_send.php
<?php
if ( isset( $_POST['Submit'] ) ) {
$email_to = "Name@gmail.com";
/**
* JUST SHORTENED FOR THIS EXAMPLE
*/
// save the return of the mail function, if you are using the @
$sent = @mail( $email_to, $email_subject, $email_message, $headers );
echo json_encode( array( "success" => $sent ) ); // return something that you can use in javascript
}// <<<<<<< YOU FORGOT THIS
?>
提示：來自jQuery 文檔：
注意：只有“成功控制”被序列化為字符串。 沒有提交按鈕值被序列化，因為表單不是使用按鈕提交的。
所以你的if永遠不會是真的，因為你正在使用序列化
if ( isset( $_POST['Submit'] ) ) {
只需將其更改為
if ( isset( $_POST['first_name'] ) ) {
或在您的表單中添加一個名為“提交”的隱藏輸入字段
<form name="htmlform" id="htmlform" method="post" action="html_form_send.php">
<input type="hidden" name="Submit" value="some value" />

如果您提交表單，您將被發送到您在action參數中指定的文檔。
如果您想將數據發送到您的 php 而不加載到不同的頁面，您可以使用 ajax 調用，您可以通過 javascript 在 buttonclick 上調用它，或者只是簡單地將您的 php 與您的 html 文檔合並並在您的action引用一個“#”范圍。
在表單提交中，PHP文件將以新頁面而非執行腳本的形式打開
