So i have an post input where i submit data something simple.
<form method="post" action="result.php">
<input type="url" name="url" class="form-control" placeholder="http://example.com/">
<input type="submit" name="submit" />
</form>
After the html code is going to be executed a php code which echo success or something like this that doesn't matter.
But i have a problem when i include('submit.php') it's going to show also the input and i don't want this.
How i can do that to don't show the input on result.php?
If you want it to be user-specific, you can try to use cookies or sessions like this:
index.php
<?php
session_start();
?>
<?php if(!isset($_SESSION['show_button']) && !$_SESSION['show_button'] ){ ?>
<!-- Button logic here... -->
<?php } ?>
result.php
// If the url has been entered, it returns a false from empty()
$_SESSION['show_button'] = empty($_POST['url']);

After submitting data from a form, I want to be redirected to a page, here's my code :
<form action="#result" method="POST">
<input name="zipcode" type="text" placeholder="Your ZipCode" />
<input name="zipcode_submit" type="submit" value="Send" />
</form>
<div id="result">
<?php
if(isset($_POST['zipcode_submit'])) {
header("Location: http://twitter.com");
}
?>
</div>
It does not work for me and I don't know why
Thanks for your help
try to shift the php code, above the form tag,i.e
<?php
if(isset($_POST['zipcode_submit'])) {
header("Location: http://twitter.com");
}
?>
above
<form action="#result" method="POST">
Have a look at php.net docs regarding the header function. It has to be the first output to the website. Put your form at the end of the file.
<html>
<?php
/* this will produce an error, header must be the first output on the website */
header('Location: http://www.example.com/');
exit;
?>
You should place a exit; after the header statement, to fully prevent the following code from being executed.
First time i try to create a simple form using the POST method.Problem is when i click the button nothing gets echoed.
here is my insert.php file :
<?php
if(isset($_POSΤ["newitem"])){
echo $itemnew = $_POSΤ["newitem"];
}
?>
<form action="insert.php" method="POST" >
<input type="text" name="newitem">
<input type="submit" value="Save">
</form>
EDIT: I tried the GET method and it works...Any ideas why that happened? Server configurations?
NEW EDIT: So it turns out i switched method to GET and it worked.Then i switched back to POST (like the code i posted on top) and it works...I have no clue why this happened.Any suggests?
The code you have posted is perfectly valid and should work.
I'm going to guess that you do not have PHP enabled, or it is not working.
<?php ... ?> looks to the browser like a long, malformed HTML tag, and therefore ignores it, making the effect invisible.
Try right-clicking the page and selecting View Source. If you see your PHP there, then the server is indeed not processing it.
The most likely reason for this is probably the same problem I had with my very first bit of PHP code: you're trying to "run" it directly in your browser. This won't work. You need to upload it to a server (or install a server on your computer and call it from there)
Use !empty($_POST['newitem'] instead:
if(!empty($_POSΤ["newitem"])){
echo $itemnew = $_POSΤ["newitem"];
}
empty()
Try the following:
if($_POST) {
if(!empty($_POST['newitem'])) {
$itemnew = $_POSΤ['newitem'];
echo $itemnew;
// or leave it as is: echo $itemnew = $_POSΤ['newitem'];
}
}
?>
<form action="insert.php" method="POST" >
<input type="text" name="newitem">
<input type="submit" value="Save">
</form>
The if($_POST) will make sure the code is only executed on a post. The empty() function will also check if it isset() but also checks if it is empty or not.
Try this :
<?php
if(isset($_POSΤ["newitem"])){
echo $itemnew = $_POSΤ["newitem"];
}
?>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="POST" >
<input type="text" name="newitem">
<input type="submit" value="Save">
</form>
$_SERVER['PHP_SELF']; is pre-defined variable in php.It allows the user to stay on same page after submitting the form.
I have a PHP form that is located on file contact.html.
The form is processed from file processForm.php.
When a user fills out the form and clicks on submit,
processForm.php sends the email and direct the user to - processForm.php
with a message on that page "Success! Your message has been sent."
I do not know much about PHP, but I know that the action that is calling for this is:
// Die with a success message
die("<span class='success'>Success! Your message has been sent.</span>");
How can I keep the message inside the form div without redirecting to the
processForm.php page?
I can post the entire processForm.php if needed, but it is long.
In order to stay on the same page on submit you can leave action empty (action="") into the form tag, or leave it out altogether.
For the message, create a variable ($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)
It is very difficult for me to put in words my query. But I will try.
I have a site xyz.com which has search facility for listed products. The search page url is generated like this :www.wyz.com/search/search_term
I want to create a iframe page in a third party site with a search facility which can directly communicated with my site xyz.com.
I have tried to create a search box with a submit button. I want to append the search query in as a variable to my form action url string.
So the search string should look like this :www.wyz.com/search/my_string_variable
The code I have written is:
<?php
$url='http://www.xyz.com/search/';
?>
<?php
if (isset($_POST['submit']))
{
$r1=$_POST['num1'];
}
?>
<?php
$result=$url.$r1
?>
<html><body>
<form action="<?php echo $result; ?>" method="post">
Num1:<input name="num1"><br>
<input type="submit" name="submit">
</form>
</body></html>
==================================================================
But output what I get, is only "http://www.xyz.com/search/". It removes my variable from the url. I am not able to find what is the reason? I have also tried to print result via to check the actual output and it shows that it has added the value at the end of url. But when I want to achieve the same thing via form action it does not work. please help?
<?php
$url='http://www.xyz.com/search/';
?>
<?php
if (isset($_POST['submit']))
{
$r1=$_POST['num1'];
$result=$url.$r1;
header("location:$result");
}
?>
<html><body>
<form action="" method="post">
Num1:<input name="num1"><br>
<input type="submit" name="submit">
</form>
</body></html>
Please try the above code. I have made some modifications. The main reason your code is not working is whenever you press the submit button it is going to the the url "http://www.xyz.com/search/" directly .The if condition is never executed. In the above mentioned code it will work properly
action="" - you are submitting to the wrong url. Here is alternate version -
<?php $url='http://www.xyz.com/search/';
if (isset($_POST['submit'])) {
$r1=$_POST['num1']; header("Location: ".$r1); // 302 redirection
}
?>
<html><body> <form target="_SELF" method="post"> Num1:<input name="num1" type="text" /><br /> <input type="submit" name="submit" /> </form> </body></html>
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";
}
