<p>There are two ways of doing it:</p>
<ol>
<li><p><strong>Submit the form to the same page</strong>: Handle the submitted form using PHP script. (This can be done by setting the form <code>action</code> to the current page URL.)</p>
<pre><code>if(isset($_POST['submit'])) {
    // Enter the code you want to execute after the form has been submitted
    // Display Success or Failure message (if any)
  } else {
    // Display the Form and the Submit Button
}
</code></pre>
</li>
<li><p><strong>Using AJAX Form Submission</strong> which is a little more difficult for a beginner than method #1.</p>
</li>
</ol>


blocks|key|3805783|text|您必须使用类似如下的代码：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3805784|echo+"<div+id='divwithform'>";

if(isset($_POST['submit']))++//+if+form+was+submitted+(if+you+came+here+with+form+data)

{

}+

echo+"</div>";|code-block|syntax|javascript|3805785|使用这样的if编写代码对于许多页面来说是很典型的，但是这是非常简单的。|offset|length|style|CODE|3805786|通常，你必须在第一个"+if“中验证一些数据(检查表单域是否为空等)。|3805787|请访问www.thenewboston.org或phpacademy.org。有非常好的PHP视频教程，包括表单。|3805788|entityMap|0|LINK|mutability|MUTABLE|url|http://www.thenewboston.org/|1|http://phpacademy.org/^0|0|0|5|2|0|0|3|K|0|O|E|1|0^^$0|@$1|2|3|4|5|6|7|10|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|11|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|12|8|@$I|13|J|14|K|L]]|9|@]|A|$]]|$1|M|3|N|5|6|7|15|8|@]|9|@]|A|$]]|$1|O|3|P|5|6|7|16|8|@]|9|@$I|17|J|18|1|19]|$I|1A|J|1B|1|1C]]|A|$]]|$1|Q|3|-4|5|6|7|1D|8|@]|9|@]|A|$]]]|R|$S|$5|T|U|V|A|$W|X]]|Y|$5|T|U|V|A|$W|Z]]]]

<p>You have to use code similar to this:</p>

<pre><code>echo "&lt;div id='divwithform'&gt;";

if(isset($_POST['submit']))  // if form was submitted (if you came here with form data)
{
    echo "Success";
}
else                // if form was not submitted (if you came here without form data)
{
    echo "&lt;form&gt; ... &lt;/form&gt;";
} 

echo "&lt;/div&gt;";
</code></pre>

<p>Code with <code>if</code> like this is typical for many pages, however this is very simplified.</p>

<p>Normally, you have to validate some data in first "if" (check if form fields were not empty etc).</p>

<p>In order to stay on the same page on submit you can leave action empty (<code>action=""</code>) into the form tag, or leave it out altogether.</p>

<p>For the message, create a variable (<code>$message = "Success! You entered: ".$input;"</code>) and then echo the variable at the place in the page where you want the message to appear with <code>&lt;?php echo $message; ?&gt;</code>.</p>

<p>Like this:</p>

<pre><code>&lt;?php
$message = "";
if(isset($_POST['SubmitButton'])){ //check if form was submitted
  $input = $_POST['inputText']; //get input text
  $message = "Success! You entered: ".$input;
}    
?&gt;

&lt;html&gt;
&lt;body&gt;    
&lt;form action="" method="post"&gt;
&lt;?php echo $message; ?&gt;
  &lt;input type="text" name="inputText"/&gt;
  &lt;input type="submit" name="SubmitButton"/&gt;

<p>I have a PHP form that is located on file <code>contact.html</code>.</p>

<p>The form is processed from file <code>processForm.php</code>.</p>

<p>When a user fills out the form and clicks on submit, 
<code>processForm.php</code> sends the email and direct the user to - <code>processForm.php</code>
with a message on that page "Success! Your message has been sent."</p>

<p>I do not know much about PHP, but I know that the action that is calling for this is:</p>

<pre><code>// Die with a success message
die("&lt;span class='success'&gt;Success! Your message has been sent.&lt;/span&gt;");
</code></pre>

<p>How can I keep the message inside the form div without redirecting to the 
<code>processForm.php</code> page?</p>

<p>I can post the entire <code>processForm.php</code> if needed, but it is long.</p>
