Hey i'm having a problem where I cannot seem to get the value of an input using PHP, I have a form in HTML and another file named "handle.php" which i prints the value of username but when I submit It directs me to the file "handle.php" and does not print anything, just shows the script.
I tried doing the script inside the HTML but I got the same result, nothing happened so I thought maybe I need to make a function and then call it onclick but it didn't do anything eventually I made a separate file named "handle.php" and in the form I did "action="handle.php" which lead to the first problem.
HTML:
<!DOCTYPE html>

<button type="submit">Sign In</button>
</form>
</section>
</div>
</body>
</html>
handle.php:
<?php
echo $_POST['login[username]'];
?>
By using this name="login[password]" you can get the values in PHP as:
print($_POST['login']['password']);
One more solution, store input array in a variable like:
$post = $_POST['login'];
then, use like:
echo $post['password']
$_POST['login']; will return a php array with all keys you used in your form. So you get the username key of this array like this:
echo $_POST['login']['username'];
first try to print only $_POST then you see what is you get in request.
always help to you for following this method. debug step by step then get the data into array.
<?php
$request=$_POST['login'];
echo $request["username"];
echo $request["password"];
?>
Replace textbox name as username in html code and Change php code as echo $_POST['username']; in handle.php
In Html code,
<input required name="username" type="text" autocapitalize="off" autocorrect="off" />
In php code( handle.php),
echo $_POST['username'];

So i have a file with PHP and HTML in it. The HTML works fine but when i enter the PHP it does not render anything for some reason. See code for beter refrence.
Also logs don't really say anything about the issue.
This fails to do anything
<?php
echo $_POST['naam'];
die();
?>
<!DOCTYPE html>
<html>
<head>
<title>Scouts Permeke</title>
<link rel="stylesheet" type="text/css" href="siteStyle.css">

<form action="login.php" method="POST">

<input name="psw" type="password" id="psw" class="form-control" placeholder="Passwoord"/><br>
<button type="submit">Login</button>
</form>
</body>
</html>
But this shows my HTML as intended.
<!DOCTYPE html>

</form>
</body>
</html>
You need to check if the variable is actually set, otherwise it will always print out the content of $_POST['naam'] without bothering if the user already inputted data and pressed the Submit-button.
if(isset($_POST['naam'])) {
echo $_POST['naam'];
die();
}
That is because it is ignoring an error as the $_POST array doesn't have the "naam" variable and your php.ini for display error is off. In php, if the array doesn't contain the key it will throw error and in this the error is ignored because of the production settings. Also, this is the reason why the "die();" line is not interpreted. Please check if php.ini has or commented
display_errors: Off
and make it into
display_errors: On
Restart apache to getting the settings work.
You can also remove/comment the first line of code in PHP tag and see if die() is working. Please do let us know if this fixed your error.

Reply
If I understand correct you need to be able to read your "id" variable after you post the form. To achieve this use $_REQUEST instead of $_GET, like this:
$id = $_REQUEST['id'];
And also pass the variable with your form, as a hidden field:
<form action="reply.php" method="post">
<input type="hidden" name="id" value="<?php echo $id; ?>" />
<input type="text" name="reply" />
<input type="submit" name="submit" value="reply" />
</form>
You didn't check if the fom was submitted
Enclose other PHP code after session.php inside a conditional checker such as:
if ($_POST):
You can use form tags to create a form and put the id field as hidden.
GET requests shouldn't be use to modify data
I am developing a phonegapp app. Have a simple login form in action.php file and for test purpose I am just printing the submit variable in other file see.php.
Issue is that if I include following line of code in action.php then submitted variables from form are not getting printed:
<script src="http://code.jquery.com/mobile/1.4.0/jquery.mobile-1.4.0.min.js" type="text/javascript"></script>
But If I remove the above line from action.php, form is getting submitted properly and input variables are getting printed in see.php
action.php

As you see in console ( network ) , see.php is being called and values of post are printed . You can turn your firebug ON and check the results ..
In jQuery Mobile, form submissions are automatically handled using Ajax whenever possible
To submit the form normally you can use data-ajax="false" in form
<form data-ajax="false" action="" method="">
This is my first post here and I hope that someone will be able to help me.
For the past week I have been working on a project of mine. Apparently, I have stuck with the last part.
So basically, I have an AJAX chat and when I submit a line I send (using a Post method) the whole line to be analyzed (to a file named analysis.php).
The chat line is being analyzed and find the variable I needed by doing queries on a MySql Database.
All I need now, is to have this variable taken with JQuery-AJAX and put it on a div in my html file(so it can be displayed on the right-left-whatever of the chat).
Here are my files :
analysis.php
<?php
$advert = $row[adverts];
?>
ajax-chat.html
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>AJAX Chat</title>
<link rel="stylesheet" type="text/css" href="js/jScrollPane/jScrollPane.css" />
<link rel="stylesheet" type="text/css" href="css/page.css" />
<link rel="stylesheet" type="text/css" href="css/chat.css" />
</head>
<body>
<div id="chatContainer">
<div id="chatTopBar" class="rounded"></div>
<div id="chatLineHolder"></div>
<div id="chatUsers" class="rounded"></div>
<div id="chatBottomBar" class="rounded">
<div class="tip"></div>
<form id="loginForm" method="post" action="">
<input id="name" name="name" class="rounded" maxlength="16" />
<input id="email" name="email" class="rounded" />
<input type="submit" class="blueButton" value="Login" />
</form>
<form id="submitForm" method="post" action="">
<input id="chatText" name="chatText" class="rounded" maxlength="255" />
<input type="submit" class="blueButton" value="Submit" />
</form>
</div>
</div>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script src="js/jScrollPane/jquery.mousewheel.js"></script>
<script src="js/jScrollPane/jScrollPane.min.js"></script>
<script src="js/script.js"></script>
</body>
</html>
So, I am basically trying to get the $advert from the analysis.php file(after the whole analyze is done) , and by using JQuery/AJAX pass it eventually to the ajax-chat.html file.
Any help is really appreciated. I have googled everything but haven't found something to help me.
Thanks in advance.
If I understand right, you need to use JSON. Here is a sample.
In your PHP write:
<?php
// filename: myAjaxFile.php
// some PHP
$advert = array(
'ajax' => 'Hello world!',
'advert' => $row['adverts'],
);
echo json_encode($advert);
?>
Then, if you are using jQuery, just write:
$.ajax({
url : 'myAjaxFile.php',
type : 'POST',
data : data,
dataType : 'json',
success : function (result) {
alert(result['ajax']); // "Hello world!" alerted
console.log(result['advert']) // The value of your php $row['adverts'] will be displayed
},
error : function () {
alert("error");
}
})
And that's all. This is JSON - it's used to send variables, arrays, objects etc between server and user. More info here: http://www.json.org/. :)
I'm building my first PHP website (attempting to, anyway!), and I'm trying to create a contact form whose contents are submitted to me via email. I've got the email part down, but I'm having trouble getting the form ("contact.php") to accept data. It automatically refreshes as soon as I type a character in any field. Here's the relevant code:
<div class="contactform">
<form name="contactform" method="post" action="contact-receiver.php">
<fieldset><legend><strong>Required Information</strong></legend>
First Name: <input type="text" name="firstName" size="35" maxlength="30"/>
Last Name: <input type="text" name="lastName" size="35" maxlength="30"/>
Email: <input type="text" name="emailAddress" size="60" maxlength="55"/>
</fieldset>
<input type="submit" value="Submit"/>
<input type="reset" value="Reset"/>
</form>
</div>
This works fine when tested independent from the rest of the site. However, here's the context:
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">
<head>
<link rel="stylesheet" type="text/css" href="styles.css" />
</head>
<body>
<?php include 'header.php'; ?>
<?php
$id = $_GET['id'];
switch($id)
{
case 'main':
include 'storeinfo.php';
break;
case 'shop':
include 'inventory.php';
break;
case 'cart':
include 'cart.php';
break;
case 'contact':
include 'contact.php';
break;
default:
include 'error.php';
}
?>
<?php include 'footer.php'; ?>
</body>
</html>
"contact.php" works fine when displayed as a separate page, but won't accept any input when accessed as an include file. If I try to enter data in any of the fields, the page immediately refreshes after I type the first character, and the data is lost.
If anyone could point me in the right direction, I would really appreciate it!
EDIT
Disabling Javascript didn't work. I cleared my cache and restarted my browser (Firefox) just to be sure. While I'm working on that voodoo priest, here's the page source for index.php?id=contact:

It sounds like a Javascript-related problem.
Check and make sure you're not including any scripts which try to autocomplete, as being misconfigured might cause it to send a request upon key up which would cause the behavior you're mentioning.
An easy way to test this is to disable JavaScript in your browser and see if the issue continues. If it does, it means you have ghosts in your computer and should see a voodoo priest. If the issue doesn't persist, it means it's an issue with some JavaScript on your site.
Posting some contents of header.php will help, as well. OR, you could simply post the complete HTML page source once - that is, visit your index.php?id=contact page, hit view source, and show that here.
