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 updated the question.
Since the last code was pretty complex and even after fixing the stuff it didn't work, I executed the below simple code to check if things work. Even this code doesn't work. Whenever I click on the submit button, it again returns a 404 error.
Yes, I placed the PHP code in the body as well to check if this work but it doesn't.
<?php
if(isset($_POST['submit'])) {
echo("Done!!!!");
} else {
?>
<html>
<head>
<title>Echo results!</title>
</head>
<body>
<form action="<?php echo $_SERVER['PHP_SELF'] ?>" method="post">
<input name="submit" type="submit" value="submit"/>
</form>
<?php
}
?>
</body>
</html>
Try giving the button_create as name of the submit button
<form action="<?php echo $_SERVER['PHP_SELF'] ?>" method="post">
if(isset($_POST['button_create'])) {
<td><input type="submit" name="button_create" id="button_create" value="Create Table!"></td>
change these lines see how you go from there
There are a couple of things wrong here, method should be POST instead of GET. The name attribute of text fields should be used when receiving the values. The submit button name should be used to check whether the button is clicked or not. See the example given below.
<?php
if (isset($_POST['submit'])) {
$ex1 = $_POST['ex1'];
$ex2 = $_POST['ex2'];
echo $ex1 . " " . $ex2;
}
?>
<form action="" method="post">
Ex1 value: <input name="ex1" type="text" />
Ex2 value: <input name="ex2" type="text" />
<input name="submit" type="submit" />
</form>
Echo results!
<?php
if(isset($_POST['submit'])) {
echo("Done!!!!");
} else {
?>
<form action="<?php echo $_SERVER['PHP_SELF'] ?>" method="post">
<input name="submit" type="submit" value="submit"/>
</form>
<?php
}
?>
this is for your updated question
I'll preface this with I'm not a coder nor aspiring to become one.
I just want to play around with something simple.
Please don't feel bad about spoon-feeding me here haha.
All I want is when I hit a my submit button the text entered in the text field is saved to a file called log.text
I want it to overwrite each time.
Once data has been written I want it to redirect to another page.
Tried this but it doesn't create the file nor write to it even if I create it manually. The redirect also doesn't work because I'm an idiot.
Any help guys? :(
<?php
$email = $_REQUEST['email'];
$file = fopen("log.txt","a+");
fwrite($file,$email);
print_r(error_get_last());
header("Location: http://www.example.com/");
?>
<form action= "" method="post" name="form">
<input type="text" name="email">
<br>
<br>
<input type="submit" name="submit" value="submit"><br>
</form>
It is because the action element of the form is empty.
It should be \n
<form action="action.php(or any other php file that is handling the form)" method="post" name="form">
This guide offered me the solution I was after.
Thanks anyway guys!

Because you dint checked whether the form is submitted or not. if submited create log. code given below
<?php
if(isset($_REQUEST['submit']))// if to check whether submit name is passed or not
{
$email = $_REQUEST['email'];
$file = fopen("log.txt","a+");
fwrite($file,$email);
print_r(error_get_last());
header("Location: http://www.example.com/");
}
?>
<html>
<form action= "" method="post" name="form">
<input type="text" name="email">
<br>
<br>
<input type="submit" name="submit" value="submit"><br>
</form>
</html>
I have this very basic form in my html page.
<form action="post.php" method="post">
Message: <input type="text" name="message" />
<input type="submit" name="submit" value="send">
</form>
and then stores the data onto my database backend.
id also want to submit data via URL bar, such as this.
http://localhost/test.php?message=test&submit=send
but when i try to do above, nothing happens.
how can i achieve such method?
[EDIT]
my post.php
<?php
include_once("connect.php");
if (isset($_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 $_REQUEST['message']
use a form GET method. to submit data of a form as a query string.
<form action="test.php" method="GET">
I have a PHP form that is located on file contact.html.
The form is processed from file processForm.php.
When a user fills out the form and clicks on submit,
processForm.php sends the email and direct the user to - processForm.php
with a message on that page "Success! Your message has been sent."
I do not know much about PHP, but I know that the action that is calling for this is:
// Die with a success message
die("<span class='success'>Success! Your message has been sent.</span>");
How can I keep the message inside the form div without redirecting to the
processForm.php page?
I can post the entire processForm.php if needed, but it is long.
In order to stay on the same page on submit you can leave action empty (action="") into the form tag, or leave it out altogether.
For the message, create a variable ($message = "Success! You entered: ".$input;") and then echo the variable at the place in the page where you want the message to appear with <?php echo $message; ?>.
Like this:
<?php
$message = "";
if(isset($_POST['SubmitButton'])){ //check if form was submitted
$input = $_POST['inputText']; //get input text
$message = "Success! You entered: ".$input;
}
?>
<html>
<body>
<form action="" method="post">
<?php echo $message; ?>
<input type="text" name="inputText"/>
<input type="submit" name="SubmitButton"/>
</form>
</body>
</html>
The best way to stay on the same page is to post to the same page:
<form method="post" action="<?=$_SERVER['PHP_SELF'];?>">
There are two ways of doing it:
Submit the form to the same page: Handle the submitted form using PHP script. (This can be done by setting the form action to the current page URL.)
if(isset($_POST['submit'])) {
// Enter the code you want to execute after the form has been submitted
// Display Success or Failure message (if any)
} else {
// Display the Form and the Submit Button
}
Using AJAX Form Submission which is a little more difficult for a beginner than method #1.
You can use the # action in a form action:
<?php
if(isset($_POST['SubmitButton'])){ // Check if form was submitted
$input = $_POST['inputText']; // Get input text
$message = "Success! You entered: " . $input;
}
?>
<html>
<body>
<form action="#" method="post">
<?php echo $message; ?>
<input type="text" name="inputText"/>
<input type="submit" name="SubmitButton"/>
</form>
</body>
</html>
Friend. Use this way, There will be no "Undefined variable message" and it will work fine.
<?php
if(isset($_POST['SubmitButton'])){
$price = $_POST["price"];
$qty = $_POST["qty"];
$message = $price*$qty;
}
?>
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body>
<form action="#" method="post">
<input type="number" name="price"> <br>
<input type="number" name="qty"><br>
<input type="submit" name="SubmitButton">
</form>
<?php echo "The Answer is" .$message; ?>
</body>
</html>
You have to use code similar to this:
echo "<div id='divwithform'>";
if(isset($_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 "<form> ... </form>";
}
echo "</div>";
Code with if like this is typical for many pages, however this is very simplified.
Normally, you have to validate some data in first "if" (check if form fields were not empty etc).
Please visit www.thenewboston.org or phpacademy.org. There are very good PHP video tutorials, including forms.
You can see the following example for the Form action on the same page
<form action="" method="post">
<table border="1px">
<tr><td>Name: <input type="text" name="user_name" ></td></tr>
<tr><td align="right"> <input type="submit" value="submit" name="btn">
</td></tr>
</table>
</form>
<?php
if(isset($_POST['btn'])){
$name=$_POST['user_name'];
echo 'Welcome '. $name;
}
?>
simple just ignore the action attribute and use !empty (not empty) in php.
<form method="post">
<input type="name" name="name">
<input type="submit">
</form>
<?PHP
if(!empty($_POST['name']))
{
echo $_POST['name'];
}
?>
Try this... worked for me
<form action="submit.php" method="post">
<input type="text" name="input">
<input type="submit">
</form>
------ submit.php ------
<?php header("Location: ../index.php"); ?>
I know this is an old question but since it came up as the top answer on Google, it is worth an update.
You do not need to use jQuery or JavaScript to stay on the same page after form submission.
All you need to do is get PHP to return just a status code of 204 (No Content).
That tells the page to stay where it is. Of course, you will probably then want some JavaScript to empty the selected filename.
What I do is I want the page to stay after submit when there are errors...So I want the page to be reloaded :
($_SERVER["PHP_SELF"])
While I include the sript from a seperate file e.g
include_once "test.php";
I also read somewhere that
if(isset($_POST['submit']))
Is a beginners old fasion way of posting a form, and
if ($_SERVER['REQUEST_METHOD'] == 'POST')
Should be used (Not my words, read it somewhere)
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";
}
