Passing form values on PHP same page - php

I have a form in my page and also have different phps in the same page..how can i pass the form to one of the phps? Thank you
It goes like this.
<form action = 'samepage.php'
method='POST'>
<input>
<input type = 'submit'>
</form>
<?php
?>
<?php
?>
<?php
I want to pass the value here
?>

The form in HTML page is a structure that allow you to insert some value and then can be passed to the backend with a specific HTTP Method called as GET,POST,PUT, DELETE etc.
Here an example:
// HTML Page. index.html
<form action="page.php" method="POST">
<input type="text" name="username">
<input type="submit">
// page.php
<?php
$username = $_POST['username'];
echo "Your username is: " . $username;
?>

Manually Send Data PHP method post

i'm brazilian i does a website simple to sent a simple users data, but to do a test i want sent manually newer data in a link without need complete manual form if it run then i can use directly by my app to save all users data.
see my idea:
mywebsite.com/savedata?method=post&usernamesave=Nome&Misael&userxp=34&userid=35&userlevel=31&usermail=crod%40gmail.com&userprog1=1&userprog2=2&userprog3=23&userprog4=25&userprog5=25&userprog6=25&userprog7=100&userprog8=100&proceed=
if i can change this data from my app and using hrefs i can do this and save a simple data without a complex data connection, it's possible ?
<a href="mywebsite.com/simplepost?method=post&joao&6y"> << type of exeple.
But when i use this and press enterkey the data isn't saved into a textfile, why ?
i using this in php :
<form method="post" action="<?php echo $_SERVER['PHP_SELF'];?>">
if ($_SERVER["REQUEST_METHOD"] == "POST") {
/*Php 5.6.2 Code By : Michael S. author*/
//globais
$username = $_POST['usernamesave'];
$userxp = $_POST['userxp'];
$userid = $_POST['userid'];
}
If i got you right you want to save data using a post method. If this is what you want to accomplish, then you don't have to pass the variables in URL. This is the main difference between POST and GET method.
Now for data saving, i will assume that you all ready created a database and a table to save your information on it, so let's jump to the form and how to handle them.
<?php
/*
* First form one will be the POST method.
*/
if(isset($_POST)){
echo "post method where used from a form to send this variables";
var_dump($_POST);
}
?>
<form method="POST" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<label for="username">Username: </label>
<input type="text" name= "username">
<label for="age">Age: </label>
<input type="number" name="age"/>
<input type="submit" value="Submit">
</form>
When you click on submit the information will be sent and can be handled after.
In get method it's different you will see the variables inside the URL after hitting submit, and the same way you can send data to other pages.
<?php
/*
* Second form one will be the GET method
* Check the url.
*/
if(isset($_GET)){
echo "get method where made from a form with this variables";
var_dump($_GET);
}
?>
<form method="GET" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<label for="username">Username: </label>
<input type="text" name= "username">
<label for="age">Age: </label>
<input type="number" name="age"/>
<input type="submit" value="Submit">
</form>
Now in the url you should see something like
example.com/index.php?username=WaredNsour&age=24
I believe you are using the GET method to send information but in your PHP code, you are using the POST method to fetch them.
Try this :
if ($_SERVER["REQUEST_METHOD"] == "GET") {
/*Php 5.6.2 Code By : Michael S. author*/
//globais
$username = $_GET['usernamesave'];
$userxp = $_GET['userxp'];
$userid = $_GET['userid'];
}
In the code of your page that is processing the variables being sent, try the following (temporarily) as a test to see if variables are being sent/seen. If they are, they will be printed out.
<p>Post vars:
<?php var_dump($_POST) ?>
</p>
If nothing displays, try:
<p>Request vars:
<?php var_dump($_REQUEST) ?>
</p>
Note: in the url you posted you have: &Misael& if Misael is part of the username you should not use the & in front of it. http sees &s as separators for the variables. It will see Misael as a variable name, like: ...&Misael=something&.... If it is a space, use %20.

Get value in a textfield using GET method PHP

I have a PHP file named "delete-wish-form.php" with a form that has the following fields:
wishId (hidden field) The value of this field should be equal to a GET variable that is passed in via the URL.
So my question is if the URL is delete-wish-form.php?wishId=1 then I want my hidden field to look like this:
CODE:
<!DOCTYPE HTML>
<html>
<title>Delete Wishes</title>
<body>
<h2>Wishes Form</h2>
<?php
$wishId = $_GET['wishId'];
?>
<form method="get" action="process-delete-wish-form">
<input type="hidden" name="wishId">
<input type="submit" name="submit" value="Submit">
</form>
</body>
</html>
You should check if the wishId is define in your url param to avoid thrown error in form, and use htmlspecialchars to avoid xss attack on GET parameter
<?php
$wishId = '';
if(isset($_GET['wishId'])) {
$wishId = htmlspecialchars($_GET['wishId'],ENT_QUOTES);
}
?>
and then in your input hidden field
<input type="hidden" name="wishId" value="<?php echo $wishId;?>">

How to acess form details in php page using html 'id' attribute

i have a form having employeeNo,name and a submit button. when the form is submitted it redirects to a php page, Now the problem is i want to access the values of the form by using 'id' attribute?if possible i need the html and php code.
Is there a way to solve this Problem?
enter code here<html>
<head>
</head>
<body>
<form action="test.php" method="">
<input type="text" name='employeeNo' id="input1">
<br>
<input type="text" name='name' id="input2">
<br>
<input type="submit" id="input3">
</form>
</body></html>
In your test.php file you need to retrieve the values. Since you don't define any method in your form, by default it should be "GET"
Your php file could look like the following:
<?php
$employee_no = $_GET['employeeNo'];
$name = $_GET['name'];
I would suggest defining your form method as POST though, like the following:
...
<form action="test.php" method="POST">
...
so your php file will retrieve values from form like this:
<?php
$employee_no = $_POST['employeeNo'];
$name = $_POST['name'];

PHP form - on submit stay on same page

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)

ECHO page1.php textarea values into page2.php

I have 2 php files in my folder. In page1.php, there's a textarea, user should enter some values in it. In page2.php, it will grab what is in the textarea and work with its program. But I can't find a command that grabs the value in textarea. Can someone help me?
page1.php:
<?
$hello = "hello";
?>
<html>
<input type = "text" name = "user_input">
</input>
</html>
page2.php
<?
ob_start();
include 'page1.php';
ob_end_clean();
echo $hello;
?>
So, is there anyone that can solve this? =/
Use $_GET or $_POST in page2.php
page1.php
<?
$hello = "hello";
?>
<html>
<form method="get" action="page2.php" enctype="multipart/form-data">
<input type = "text" name = "user_input">
<input type="submit">
</form>
</html>
page2.php
<?
$text=$_GET['user_input'];
ob_start();
include 'page1.php';
ob_end_clean();
echo $hello;
echo $text;
?>
You may use either $_GET['user_input'] or $_POST['user_input'].
The difference is, you can see the data in the url (visible to everyone) when using GET method and not in the other method.
Also, always use <input> elements (which you want to pass to another file) inside a <form> and specify action="file.php", to where you want to pass data, and the method, either method="get" or method="post", like;
<form method="get" action="page2.php">
also specify the method to grab data in the target file also, like;
$text=$_GET['user_input']; or $text=$_POST['user_input'];
And in your case, you may use;
Method 1
<?php
$hello = "hello";
?>
<html>
<form method="get" action="page2.php">
<input type="text" name="user_input">
<input type="submit">
</form>
</html>
page2.php
<?php
$text=$_GET['user_input'];
echo $text;
?>
Method 2
<?php
$hello = "hello";
?>
<html>
<form method="post" action="page2.php">
<input type="text" name="user_input">
<input type="submit">
</form>
</html>
page2.php
<?php
$text=$_POST['user_input'];
echo $text;
?>
If you want to share the data over a number of pages, you may do this using PHP Session or saving the data in a cookie.
1. Using Sessions
<?php
session_start();
$_SESSION['data'] = 1; // store session data
echo "Pageviews = ". $_SESSION['data']; //retrieve data
?>
Make sure you add session_start(); on every page you want to handle session
You can read more about php sessions here www.tizag.com/phpT/phpsessions.php/
2. Using Cookie
<?php
setcookie("user", "Alex Porter", time()+3600);
?>
and retreive it using
echo $_COOKIE["user"];
You can read more about php sessions here http://www.w3schools.com/php/php_cookies.asp
hope this helps...:)
basically your page1.php is a page with some form in it with a text area. Now user will have to fill it and submit the form to page2.php. You can't echo it's content like that, because that will be on browser subject to user actions. Use a form and submit the data to page2.php. Like this:
page1.php
<html>
<head>
</head>
<body>
<form action="page2.php" method="post">
<textarea name="t1">
</textarea>
</form>
</body>
</html>
page2.php
<?php
$textAreaContents = isset($_POST['t1'])?$_POST['t1']:'';
echo "You submitted: ".$textAreaContents;
?>
if i were you i should use sessions for this. that is where they were made for..
example:when user clicks on submit.
<?php
if($_SERVER['REQUEST_METHOD'] == 'POST')
{
$_SESSION['post'] = $_POST;
}
that is where every post variable will be put in a session.
and your inputbox will be something like this..
<textarea name="message" type="text" value="" rows="0" cols="0" placeholder="" ><?php if(isset($_SESSION['post'])){echo $_SESSION['post']['message'];} ?></textarea>
?>
note that you now can use every post variable that you used in your form by echo (example)
echo $_SESSION['post']['message']
where message is the name of the inputbox. in this case of the textarea
don't forget that at the end when you don't want to use the session anymore use session_destroy(); otherwise you will keep having it in your form. and don't forget session_start(); above every page where you are planning to use sessions ( it must be at 1st line of your document at all times)
