submit form to self
提问by max_
At the moment, I have a form with an input (text) and a button to submit the form.
目前，我有一个带有输入（文本）的表单和一个用于提交表单的按钮。
The form is posted to 'submit.php'. I would like the form posted to same page as the form.
表单被发布到'submit.php'。我希望将表格发布到与表格相同的页面。
How can I do this?
我怎样才能做到这一点？
<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
提交.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!");
}
?>

I think you have a couple of options here.
我认为你在这里有几个选择。
Submit the form onto itself
将表单提交到自身
<?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
重定向回表单
Add something like this in submit.phpwhere you want to show the form.
在submit.php要显示表单的位置添加类似的内容。
<?php
header('Location: http://example.org/form.php');
exit;
?>
