Hi guys I'm trying to build a form wich allow me to create cookies, and I want to be able to delete them as well, to do that there is an option at the bottom of the form that send me to my file call see_cookies.php that generate another form with some php to create a loop that will go through al the $_COOKIE array and print every checkbox with the information. Also some submit buttons with allows my to delete all or the ones I choose, but I'm not able to delete them.
Could anyone help me please.
this is the code for see_cookies.php:
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Ver::Cookies</title>
</head>
<body>
<h1>Cookies en el sevidor</h1>
<form action="delete_cookies.php" method="post">
<?php
foreach ($_COOKIE as $nombre => $contenido) {
print <<<pinta
<input type="checkbox" name="nombre_cookie[]" value="$nombre"/>$nombre($contenido)<br>
pinta;
}
?>
<input type="submit" value="Delete" name="delete">
<input type="submit" value="Delete_All" name="delete_all">
</form>
</body>
</html>
this is the code for delete_cookie.php
<?php
function delete_cookie($nombre){
setcookie($nombre," ",-10);
}
if(isset($_POST["delete_all"])){
foreach ($_COOKIE as $nombre => $contenido ) {
delete_cookie($nombre);
}
}elseif(isset($_POST["delete"])){
foreach ($_POST["nombre_cookie"] as $key => $contenido) {
delete_cookie($contenido);
}
}
?>
try time less than current time.
setcookie($nombre, "", time()-3600);
Your second file is named delete_cookie.php when the form action goes to delete_cookies.php. I think that's the problem.

I want to Create an ItemList and simply display it. For this, I have created an array and a form with add item "text field" and "submit" button.
The problem is when I add a new value by clicking on the "submit" button, the page gets reloaded and previously added values are lost. I want previously added values to persist, without storing these data into the database.
Please help me I am a beginner in this field.
Code :
<?php
session_start();
?>
<!DOCTYPE html>
<html lang="en" dir="ltr">
<head>
<meta charset="utf-8">
<title>PHP ItemList</title>
</head>
<body>
<div class="container">
<?php
$itemList = array();
if ( $_SERVER["REQUEST_METHOD"] == "POST") {
array_push( $itemList, $_POST["Item"] );
print_r( $itemList );
}
?>
<h3>Add : </h3>
<form method="POST" action = "index.php">
<p>Item : <input type="text" name="Item"></p>
<input type="submit" name="submit" value="submit">
</form>
</div>
</body>
</html>
My goal from my code (using only HTML and PHP) is to provide a page for choosing the type of question (checkbox...) with the number of inputs and display the result in a different page by reading the 3 files that has been already saved in 3 main files (file for questions, file for number of inputs, file for options content), my idea is almost.
Here's my code from the displaying page :
<!doctype html>
<html>
<head>
<title>
form du reponse
</title>
</head>
<body>
<?php
//3 files
$k=fopen("choix multiples.txt","a+");//questions
$nn=fopen("nombre.txt","a+");//number of inputs
$no=fopen("les_options_multiples.txt","a+");//options content
//from here it only reads the first line of $nn and it keeps using it on the last loop
for($lol=fgets($nn);!feof($nn);$lol=fgets($nn))
{
for($questioncm=fgets($k);!feof($k);$questioncm=fgets($k))
{
echo "$questioncm :<br/>";
for($x=1;$x<=$lol;$x++)
{
echo fgets($no);
?>
<form action="" method="POST">
<div>
<input name="haha" type="radio" value="hahaha">
</div>
<?php
}
?>
</form>
<?php
}
}
</form>
</body>
</html>
I'm wondering if it would be possible to place two forms on the same page
and saving their cookie values respectively after clicking submit buttons.
With code below, when I click submit button on the first form, its cookie value is saved successfully but when I click on the second form, second value is saved but the first value is overwritten.
<?php
setcookie('username[user111]', $_POST['user111'], time()+60);
setcookie('username[user222]', $_POST['user222'], time()+60);
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<p>name：<?php echo $_POST['user111']; ?></p>
<form method="POST" action="">
<input type="hidden" name="user111" value="TOM">
<input type="submit" value="close">
</form>
<p>name：<?php echo $_POST['user222']; ?></p>
<form method="POST" action="">
<input type="hidden" name="user222" value="BOB">
<input type="submit" value="close">
</form>
</body>
</html>
I'd like to save both
Name:username[user111] Value:BOB
Name:username[user222] Value:TOM
If I could save the values respectively, it'd not necessary to use form submit
but if possible I'd like to use PHP instead of JavaScript.
Any advice would be appreciated.
I have a form and added a session_starts I want to track of how many times I have visited the page ..I want a Button indicating the stop session and the session should stop and start with a new session ...How do I do this?
Suggestion:
Try creating a button in a form and after submitting it change session values to what you want and the start another.
Example
<form method="POST">
<input type="submit" name="emptySession">
<form>
<?php
if(isset($_POST['emptySession']){
//you continue
}
?>
I'd have thought that something like the following ought to work- the logic can be adapted to suit whatever page you have.
<?php
session_start();
if( !empty( $_POST['reset'] ){
#session_unset();
#session_destroy();
#session_start();
#session_regenerate_id( true );
}
?>
<!doctype html>
<html>
<head>
<meta charset='utf-8' />
<title>Sessions</title>
</head>
<body>
<form method='post'>
<input name='reset' value='Reset' type='submit' />
</form>
</body>
</html>
I am building a confirmation page and a simple shopping cart script. But I am unable to send the values by mail using the "Send" button which I have put on the end of the page.
If I don't wrap the mailer part inside the "if" condition for the button, it works and sends the stuff on page load. But as I wrap it inside the "if" condition, I get only a blank email.
UPDATE:
Inside the previous page, wich has the "Ordering" form, I have switched from method="post" to method="get".
And in the second page,
I have changed the method inside the loop from $_POST to $_GET. As for the button kept the $_POST method together with the method="post" inside the form (on the bottom). Now it works, but I can't understand why.
First page with form:
<!DOCTYPE html>
<head>
<title>Alm Chalet Menu</title>
<link href="css/template.css" type="text/css" rel="stylesheet" />
</head>
<body>
<h2>Alm Chalet Menu</h2>
<p>Biologische Säfte </p>
<form method="get" action="order.php">
<p><input type="number" name="orange" min="0" value="0" class="count_style">
Orange</p>
<p><input type="number" name="multivitamine" min="0" value="0" class="count_style">Multivitamine</p>
<input type="submit" name="send" value="Send Menu" />
</form>
</body>
</html>
Second, confirmation page:
<!DOCTYPE html>
<head>
<link href="css/template.css" type="text/css" rel="stylesheet" />
<title>Ordered Food</title>
</head>
<body>
Your order the following:
<table id="order_table">
<tbody>
<?php
$items = '';
foreach($_POST as $key => $value){
if ($value == 0) {
continue;
}
echo "<tr><td>$key</td><td class='value'>$value</td></tr>";
$items .= "$key: $value\n";
}
if (isset($_GET['send'])) {
$message = $items;
mail("****#yahoo.com", $subject, $message, $headers);
echo "<p>Thanks for your order!</p>";
}
?>
</tbody>
</table>
<p>
<form method="get">
<input name="send" type="submit" value="Send Order">
</form>
</p>
</body>
</html>
I assume you are sending post data from some other page to this page? If so after you post to this page then submit another form using the get method, the $_POST variable will no longer have anything in it because you submitted another form to this page (via get). You need some way of saving the posted data (perhaps a php session) so that when you click the Send Order submit button the previously posted data isn't lost.
