I have a form where you can send an email to someone, if i reload the page it sends anouther email. How do I make it so it does not do that? A forum said to change it to GET, that did not work either. mail function is not showing up.
<form action="index.php" method="GET">
<textarea name="comment" cols="16.5" rows="5" style="resize: none;" maxlength="240"> </textarea>
<input type="submit" value="Send Comment" />
<?php
if (isset($_GET['comment'])) {
$com = mysql_real_escape_string($_GET['comment']);
if (!empty($com)) {
if (strlen($com) <= 240 && strlen($com) >= 5) { $mail = mail('__________', 'Comments', $com);
}
}
}
?>
</form>
Send your form with POST to another page: say upload.php, then in upload.php you add this code after you have checked the form:
header( 'Location: form_page.php' );
that way the form page can be reloaded without having this issue.
Add a GET parameter (say for eg: sent) to the link (index.php) and check if it is not set before sending the mail.
<form action="index.php?sent=true" method="GET">
<textarea name="comment" cols="16.5" rows="5" style="resize: none;" maxlength="240"></textarea>
<input type="submit" value="Send Comment" />
<?php
if (!isset($_GET['sent'])) {
// Your code for sending the mail here...
}
?>
</form>

would it be possible to have a html/php template on index.php say for example (a news webpage template and then anyone can edit the title, paragraphs only, then on submit it then sends the webpage with the data stored to a paste bin like url so who ever visits that url say http://localhost/news/jjeh3bndjks they would only be able to view to content and not edit.
I would like to use something like this
<?php
if ($_POST) {
$pasteID = uniqid();
$paste = fopen("pastes/".$pasteID.".php", "w");
$contents = $_POST['pasteContents'];
fwrite($paste, $contents);
header('Location: /pastes/'.$pasteID.'.php');
}
?>
<form action="" method="POST">
<input type="text" name="pasteContents" placeholder="write here" />
<button type="submit" tabindex="0">submit</button>
</form>
but for some reason when i add another input box or try to send anymore data it fails or just gives me the last input given is there a way to send a whole page this way?
any help would be appreciated
You can use file_get_contents with the following code:
<?php
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
parse_str(file_get_contents('php://input'));
echo param1 . '<br />' . param2;
} else {
?>
<form method="post">
<input type="text" name="param1" value="param1" />
<input type="text" name="param2" value="param2" />
<input type="submit" value="submit" />
</form>
<?php } ?>
(You can test it here)
Although, I did success to use $_POST too:
<?php
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
echo $_POST['param1'] . '<br />' . $_POST['param2'];
} else {
?>
<form method="post">
<input type="text" name="param1" value="param1" />
<input type="text" name="param2" value="param2" />
<input type="submit" value="submit" />
</form>
<?php } ?>

I want to echo something once a form is submitted. But when I click the submit button, it seems that the page is just refreshing itself and I do not see the word that I have written in the echo section. Here is my code:
<?php
if (isset($_POST['submit'])) {
echo "submitted";
}
?>
<h3>Post your form here</h3>
<form method="post" action="<?php $_SERVER['PHP_SELF']; ?>">
<label>Insert a title here</label><br>
<input name="title" type="text" placeholder="add a title"><br><br>
<label>Insert the body here</label><br>
<textarea name="body" placeholder="insert the body here "></textarea><br><br>
<input type="submit" value="submit" name="submit"><br>
</form>
I also tried the code by removing the isset function, but that did not work, either.
In form action, you have missed an echo.
action="<?php echo $_SERVER['PHP_SELF']; ?>"
This is working code. I test it on my Machine.
Why you don't use else statement to test it better.
here is the code.
Note (Check your localhost server settings)
<?php
if (isset($_POST['submit'])) {
echo "submitted";
}
else
{
echo "Not working";
}
?>
<h3>Post your form here</h3>
<form method="post" action="<?php $_SERVER['PHP_SELF']; ?>">
<label>Insert a title here</label><br>
<input name="title" type="text" placeholder="add a title"><br><br>
<label>Insert the body here</label><br>
<textarea name="body" placeholder="insert the body here "></textarea><br>
<br>
<input type="submit" value="submit" name="submit"><br>
</form>
Actually the credit goes to #ashok. He was right that I needed to check localhost server settings.
I am using Phpstorm to write PHP codes. Whenever I click on the Chrome browser to see the results, it takes me to
http://localhost:63342/ name of the file page.
The port 63342 is the default port used by Phpstorm. Since I am using Xampp and it runs on port 8080. I changed port number 63342 to 8080, and it worked.
If you are submitting to the same page, you really dont need to define an action.
Instead of isset, use !empty as such
if(!empty($_POST['submit'])){
echo "success";
}
I must bring to your attention that if the suggestions don't work, you should start with debugging what you are actually receiving from the form POST, using:
<pre>
<?php var_dump($_POST); ?>
</pre>
Turning on error reporting in your php settings is also a good start for debugging.
I have this very basic form in my html page.
<form action="post.php" method="post">
Message: <input type="text" name="message" />
<input type="submit" name="submit" value="send">
</form>
and then stores the data onto my database backend.
id also want to submit data via URL bar, such as this.
http://localhost/test.php?message=test&submit=send
but when i try to do above, nothing happens.
how can i achieve such method?
[EDIT]
my post.php
<?php
include_once("connect.php");
if (isset($_GET['submit'])) {
if ($_GET['message'] == "") {
echo " no input, return";
exit();
}
else {
$message = $_GET['message'];
mysql_query("insert into data (message) values ('$message')");
header ('location:index.php');
exit ();
}
}
else {
echo "invalid";
}
?>
use GET method instead of POST
so your code should be like follow:
<form action="post.php" method="GET">
Message: <input type="text" name="message" />
<input type="submit" name="submit" value="send">
</form>
and in the post.php you can get those Query string by using $_GET['message'] or $_REQUEST['message']
use a form GET method. to submit data of a form as a query string.
<form action="test.php" method="GET">
hello i have problems sending an id in a form.
the structure of the site is:
session_start();
if (!isset($_SESSION['a'])){
...create the session from some variables...
$_SESSION['a'] = $var;
$var = $_SESSION['a'];
}else{
$var = $_SESSION['a'];
if (isset($_POST["one"]) ){
echo "post one was send";
}
if (isset($_POST["two"]) ){
echo "post en was send";
}
echo "session already exists.";
}
the form where it will be send is placed at the end of the page and will be embedded into html by an excluded php:
echo '...
<ul class="drop_down">
<form action="'.$_SERVER['PHP_SELF'].'" method="post">
<input type="submit" id="one" name="one" value="one"/><div>set one</div>
</form>
<form action="'.$_SERVER['PHP_SELF'].'" method="post">
<input type="submit" id="two" name="two" value="two"><div>set two</div>
</form>
</ul>
...';
so the strange about that is, that the form not seems to be send because the first part of the code works as it should do just the else part does not work when sending the form. it just will be displayed the echo text below the conditions for post-method.
so if there is someone who could tell how i can solve this i really would apreciate.
thanks alot.
UPDATE:
okay, using the request-method without action makes echo out the message. i thought it will work.
now the problem is, that when i will send the post the session should have been changed. this is not the case and i have no clue why this is not working.
so the original code is like that:
if (isset($_POST["tr"]) ){
$_SESSION['a'] = "tr";
echo "post tr was send and session has changed to tr";
}
If you have a forms like this
<form method="post">
<input type="submit" value="Submit Form" name="formA">
</form>
<form method="post">
<input type="submit" value="Submit Form" name="formB">
</form>
Then you can check like this
if (isset($_REQUEST['formA']) ...
elseif (isset($_REQUEST['formB']) ...
I have a simple form for a mailing list that I found at http://www.notonebit.com/projects/mailing-list/
The problem is when I click submit all I want it to do is display a message under the current form saying "Thanks for subscribing" without any redirect. Instead, it directs me to a completely new page.
<form method="POST" action="mlml/process.php">
<input type="text" name="address" id="email" maxlength="30" size="23">
<input type="submit" value="" id="submit"name="submit" >
</form>
You will need AJAX to post the data to your server. The best solution is to implement the regular posting, so that will at least work. Then, you can hook into that using Javascript. That way, posting will work (with a refresh) when someone doesn't have Javascript.
If found a good article on posting forms with AJAX using JQuery .
In addition, you can choose to post the data to the same url. The JQuery library will add the HTTP_X_REQUESTED_WITH header, of which you can check the value in your server side script. That will allow you to post to the same url but return a different value (entire page, or just a specific response, depending on being an AJAX request or not).
So you can actually get the url from your form and won't need to code it in your Javascript too. That allows you to write a more maintanable script, and may even lead to a generic form handling method that you can reuse for all forms you want to post using Ajax.
Quite simple with jQuery:
<form id="mail_subscribe">
<input type="text" name="address" id="email" maxlength="30" size="23">
<input type="hidden" name="action" value="subscribe" />
<input type="submit" value="" id="submit"name="submit" >
</form>
<p style="display: none;" id="notification">Thank You!</p>
<script>
$('#mail_subscribe').submit(function() {
var post_data = $('#mail_subscribe').serialize();
$.post('mlml/process.php', post_data, function(data) {
$('#notification').show();
});
});
</script>
and in your process.php:
<?php
if(isset($_POST['action'])) {
switch($_POST['action']) {
case 'subscribe' :
$email_address = $_POST['address'];
//do some db stuff...
//if you echo out something, it will be available in the data-argument of the
//ajax-post-callback-function and can be displayed on the html-site
break;
}
}
?>
It redirects to a different page because of your action attribute.
Try:
<form method="POST" action="<?php echo $_SERVER['PHP_SELF'] ?>">
<input type="text" name="address" id="email" maxlength="30" size="23" />
<input type="submit" value="" id="submit" name="submit" />
</form>
<?php if (isset($_POST['submit'])) : ?>
<p>Thank you for subscribing!</p>
<?php endif; ?>
The page will show your "Thank You" message after the user clicks your submit button.
Also, since I don't know the name of the page your code is on, I inserted a superglobal variable that will insert the the filename of the currently executing script, relative to the document root. So, this page will submit to itself.
You have to use AJAX. But that requires JavaScript to be active at the users Brwoser.
In my opinion it's the only way to do without redirect.
to send a form request without redirecting is impossible in php but there is a way you can work around it.
<form method="post" action="http://yoururl.com/recv.php" target="_self">
<input type="text" name="somedata" id="somedata" />
<input type="submit" name="submit" value="Submit!" />
</form>
then for the php page its sending to have it do something but DO NOT echo back a result, instead simply redirect using
header( 'Location: http://yourotherurl.com/formpage' );
if you want it to send back a success message simply do
$success = "true";
header( 'Location: http://yourotherurl.com/formpage?success='.$success);
and on the formpage add
$success = $_GET['success'];
if($success == "true"){ echo 'Your success message'; } else { echo
'Your failure message';
Return and print the contents of another page on the current page.
index.php
<html>
<body>
<p>index.php</p>
<form name="form1" method="post" action="">
Name: <input type="text" name="search">
<input type="submit">
</form>
<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
$_POST['search'];
include 'test.php';
}
?>
</body>
</html>
test.php
<?php
echo 'test.php <br/>';
echo 'data posted is: ' . $_POST['search'];
?>
Result:
Just an idea that might work for you assuming you have no control over the page you are posting to:
Create your own "proxy php target" for action and then reply with the message you want. The data that was posted to your php file can then be forwarded with http_post_data (Perform POST request with pre-encoded data). You might need to parse it a bit.
ENGLISH Version
It seems that no one has solved this problem without javascript or ajax
You can also do the following.
Save a php file with the functions and then send them to the index of your page
Example
INDEX.PHP
<div>
<?php include 'tools/edit.php';?>
<form method="post">
<input type="submit" name="disable" value="Disable" />
<input type="submit" name="enable" value="Enable" />
</form>
</div>
Tools.php (It can be any name, note that it is kept in a folder lame tools)
<?php
if(isset($_POST['enable'])) {
echo "Enable";
} else {
}
if(isset($_POST['disable'])) {
echo "Disable";
} else {
}
?>
Use
form onsubmit="takeActions();return false;"
function takeAction(){
var value1 = document.getElementById('name').innerHTML;
// make an AJAX call and send all the values to it
// Once , you are done with AJAX, time to say Thanks :)
document.getElementById('reqDiv').innerHTML = "Thank You for subscribing";
}
