提交表格给自己 [英] submit form to self

问题描述

目前，我有一个输入（文本）和一个按钮来提交表单的表单。

表单发布到'submit.php'。我希望表单发布到同一页面。

我该怎么做？

 < form action =submit.phpmethod =POST> 
< input type =textclass =emailFieldplaceholder =email addressname =email/> 
< button type =submit> 
< div class =submit/> 
< / button> 
< / form> 
  

submit.php

 <？php 
 mysql_connect（'localhost'，''，''）或die（'无法连接'）; 
 mysql_select_db（''）或死（'无法选择db'）; 
 $ query = mysql_query（）; 
 if（mysql_num_rows（$ query）> 0）{
 exit（您已订阅！）; 
} 
 else {
 mysql_query（）或die（mysql_error（））; 
 exit（您已成功订阅！）; 
} 
 
？> 
  

解决方案

我认为您在这里有几个选项。

将表单提交到自身上

 <？php 
 if（'POST'== $ _SERVER ['REQUEST_METHOD']）{
 //在此处理表单
} 
？> 
< form action =method =POST> 
< input type =textclass =emailFieldplaceholder =email addressname =email/> 
< button type =submit> 
< div class =submit/> 
< / button> 
< / form> 
  

重新导向到表格

添加在 submit.php 中你想显示表单的地方。

 <？php 
 header（'Location：http://example.org/form.php'）; 
出口; 
？> 
  

At the moment, I have a form with an input (text) and a button to submit the form.

The form is posted to 'submit.php'. I would like the form posted to same page as the form.

How can I do this?

<form action="submit.php" method="POST">
    <input type="text" class="emailField" placeholder="email address" name="email" />
    <button type="submit">
        <div class="submit" />
    </button>
</form>

submit.php

<?php
    mysql_connect('localhost', '', '') or die('unable to connect');
    mysql_select_db('') or die('unable to select db');
    $query = mysql_query("");
    if (mysql_num_rows($query) > 0) {
        exit("You have already subscribed!");
    }
    else {
        mysql_query("") or die(mysql_error());
        exit("You have successfully subscribed!");
    }

?>

解决方案

I think you have a couple of options here.

Submit the form onto itself

<?php
    if('POST' == $_SERVER['REQUEST_METHOD']) {
        // process the form here
    }
?>
<form action="" method="POST">
    <input type="text" class="emailField" placeholder="email address" name="email" />
    <button type="submit">
        <div class="submit" />
    </button>
</form>

Redirect back to the form

Add something like this in submit.php where you want to show the form.

<?php
    header('Location: http://example.org/form.php');
    exit;
?>
