I am working on a guessing game. The guessing code is working, however, when i want to click the 'give up' to display the number, is not passing the value to the give up. My apology, I am fairly new with php.
Any suggestion or hint how this could be done?
below is the guessinggame.php and the bottom one is the giveup.php
<?php
session_start();
$number = rand(1,100);
if(isset($_POST["guess"])){
$guess = $_POST['guess'];
$number = $_POST['number'];
$display = $_POST['submit'];
if ($guess < $number){
echo "The number needs to be higer!";
}else
if($guess > $number){
echo "The number needs to be lower!";
}else
if($guess == $number){
echo "Congratulation! You Guessed the hidden number.";
}
}
?>

You could store the number in the user session in your main script:
session_start();
$number = rand(1,100);
$_SESSION['number'] = $number;
Then, retrieve it in giveup.php:
$number = $_SESSION['number'];

This is my PHP file performing an HTTP request:

$fooddetail=new Food($token,"json");
$pid=$_GET['first'];
//$search='https://community-food2fork.p.mashape.com/search?key='.$token.'&q='.$pid; //Food2fork
$search='http://food2fork.com/api/search?key='.$token.'&q='.$pid;
//key
echo $search;
$json=$fooddetail->call_url($search);
//echo $details;
if(!$json){
echo 'Error: Could not retrieve products list.';
exit();
}
//var_dump(json_decode($json,TRUE));
$details=json_decode($json,TRUE);
//var_dump($details);
echo $details;
$title = $details['title'];
//print_r $title;
$publisher = $details['publisher'];
//print_r $publisher;

The script fails with an "undefine index" error message. What is the reason behind that?
I use food2fork API. The returned JSON has title and publisher keys, but when I try to display the values, the script logs the above-mentioned error message.
I am trying to find a way to check whether there is a session. And if there isn't, redirect back to the start.php page.
These are the pages I have made.
start.php
<form action="form.php" method="post">
<p>Please enter your name to continue:</p>
<input type="text" name="name" id="name" />
<input type="submit" name="enter" id="enter" value="Enter" />
</form>
form.php
Above the head:
<?php session_start(); ?>
In the body:
<?php
if(isset($_POST['enter'])){
if($_POST['name'] != ""){
$_SESSION['name'] = stripslashes(htmlspecialchars($_POST['name']));
}
}
$name = $_SESSION['name'];
echo $name;
?>
Attempt
I have putting this above the head of the form (along with what is there now) but it just keeps me on the start.php page
<?php
if (!isset($_SESSION["name"]))
{
header("location: start.php");
}
else{
}
?>
more info
So currently if there is no session and I enter form.php it will redirect me to start.php. But if there is a session it will stay on form.php.
But if I start on start.php and submit the form (creating the session and moving to form.php) it will straight away redirect me back to start.php (the same page)?
code of the two pages in full:
start.php
<?php session_start(); ob_start(); ?>

?>

What I have decide to do instead
if (strlen($name) <1){
echo '<script> window.location.replace("delete1.php");</script>';
}
You need to add
<?php session_start(); ?>
on each page in the very beginning..
So, the code should be like this
<?php
session_start();
if (!isset($_SESSION["name"]))
{
//header("location: delete1.php");
die('<meta http-equiv="refresh" content="0;URL=\'delete1.php\'" />');
}
else{
}
?>

The problem i am facing is that i am not able to login to my index.php page even after i have put in the correct username and password as specified in my database which i have set through phpmyadmin.Everytime i try to login it invokes the [echo 'This information is incorrect,try again Click Here'] as mentioned in the admin_login.php.I am getting a bit frustrated.Can you help me out guys?
I am not sure why you use the preg_replace. Looks to me you are clearing the variables. Which explains why you cant find yourself in the database. Try to remove the preg_replace and see what happens. Also when you when you the SQL query you forgot a space between your password and limit.
Hope this solves your problem
I just need a reality check. This page is redirecting to the HTTP_HOST immediately without downloading data or processing the form. It was, at one time working. I broke something but I'm blind to it.
I'm hitting the page with a query that has 1 value pair, like this: http://Nitrofill.biz/tr/Nitrofill_Presentation?num=EV4ghF8p3
Can anybody help me spot the problem?

You're missing .php in the link you have posted. It needs to be
