PHP - Reset A Counter Weekly In Php/mysql

I have a login.php that has a usual login form with a username and password textbox and a login button that redirects to index.php. when I login and go to the index.php, the welcome sign is on but after I click on a link that points to index.php itself, the "welcome, <myname>" sign is replaced with "sign in" again (the cookie disappears) even though I put a checking on top of the index.php page..

here's my code in index.php:

<?php
if ($_COOKIE['activeuser'] != '#') {
} else {
setcookie('activeuser','#',time()+60*100);
}
include('connect.php'); //this code connects to my database
if (isset($_POST['bLogin'])) {
$sql = 'SELECT * FROM user WHERE username = "'.$_POST['tfUsername'].'"';
$sql .= ' AND password = "'.$_POST['tfPassword'].'"';
$result = mysql_query($sql,$con);
if($result) {
$row = mysql_fetch_array($result);
$_COOKIE['activeuser'] = $row['name'];
} else {
echo 'query error';
}
}
if ($_COOKIE['useraktif'] != '#') {
echo '<div id="welcome">Welcome, ' . $_COOKIE['activeuser'];
echo '<br/><a href="logout.php">Logout</a></div>';
} else {
echo '<div class="signIn"><a href="login.php">sign in</a></div>';
echo '<div class="signIn"><a href="#">Register</a></div>';
}

I have an app that connects to a source safe server to perform a command via shell_exec(). I had used exec(), but shell_exec seems to work better since I am on Linux.

The command connects to the server and tells it to promote a file to the next level. On Windows this ran without a hitch, but on Linux I gat an error that reads:
Quote

Socket error when reading request from [172.20.22.1]: 3537808 ; Socket closed.

I am told that the reason for this error is that PHP broke the connection to the server before the server completed the job and was able to shutdown properly.

The only way I have found around this is to place a sleep(3) to the script. This is really not ideal since that means that there is at least 3 seconds between each command, which can really extend the time it takes to perform if there are numerous files.

If PHP breaks the connection before the program can close it will leave the program open and PHP cannot perform any more commands to the server since it is stuck on the last command. If too many are given the machine will lock up due to resources being eaten up.

I'm wanting to know if there is a way to tell PHP to not let go of a connection so quickly.

I tried "nohup", but that does not help.

I am new to Linux and am at a loss of what my options are beyond the sleep() method. I really feel that there has to be a better way or setting that can be manipulated to fix this issue altogether.

Thanks in advance for any help.

Is there a way to reset a session?

Here is my code...
Code: [Select]
<?php  
session_start(); 
if (!isset($_SESSION['logged_in'])) 
{
header("Location: login.php");
}

mysql_connect("localhost", "user", "password")or die("cannot connect"); 
mysql_select_db("database")or die("cannot select DB");

$bio = $_POST['Bio'];
$location = $_POST['Location'];
$username = $_SESSION["user_name"];

$sql = "UPDATE users SET bio = '$bio', location = '$location' WHERE username = '$username'";
$result = mysql_query($sql) or die ("Error in query: $sql. " . mysql_error());
?>
Now I have a session called bio that I need to reset so that it will store the new bio information. How can I do this? I tried to unset the session and start it again but this didn't work.

i have two drop down lists in a form and some text fields and then the SUBMIT and RESET button...when i click my first dropdown the values are populated in the second dropdown by ajax call. the problem i face is when i click on the reset button the values in the textfields and my first dropdown get reset to default value.but the value in the second drop down does not reset to the default value i have given instead it still has the value of the ajax call....any ideas to sort it out?

I want to recieve emails on weekly manner from thursday to thursday. For this how can i set the variables to pass to the sql query.

but it will  calculate date from today.
And I want to recieve emails on every friday morning.
So please write the code for me also write the end date.

Thanks in advance.

I've used this update statement before, even with parameter binding, something easy is off...   I'm trying to update a hash knowing a person's user name and email combination, this is not ideal I realize or safe. I actually generate a unique random hash per person who registers, I tell them to remember this eg. keep the email.   I don't know why the update statement is being bypassed.   So they enter username, email associated with username, new password. New password is hashed, replaces old one, redirect.   I've been echoing stuff just to see the flow of the code, what is being executed and what isn't.

if(empty($errors)){

$userrname = test_input($_POST['userrname']);
$email = test_input($_POST['email']);
$newpassword = test_input($_POST['newpassword']);

$hash = password_hash($newpassword, PASSWORD_BCRYPT, array("cost" => 9));

$stmt = $link->prepare("SELECT username,hash FROM User where username=? And email=?");
$stmt->bind_param("ss",$userrname,$email);

if($stmt->execute())
{
$stmt->bind_result($username_from_db,$hash_from_db);
    if($stmt->fetch()){
        $_SESSION['user']=$username_from_db;
    $query = "UPDATE User SET hash=$hash WHERE email=$email And username=$username_from_db";
    if($result=$link->query($query)){
    $_SESSION['status_message'] = "Password has been reset";
    }
    
    }else {
    echo "no good";
    }
    $host  = $_SERVER['HTTP_HOST'];
        $uri   = $_SERVER['REQUEST_URI']; // the path/file?query string of the page
        
        header("Location: newlocation.com");
        exit;
        $link->close();
}

is there a way to reset the array keys? to 0,1,2,3,...

also for example that i have something like this:

$array['dog']='dog';
$array['mouse']='mouse';
$array['cat']='cat';

and i want it like this:

$array[0]='dog';
$array[1]='mouse';
$array[2]='cat';

Hi all

I have a filter system on a website I am creating and there are three forms each sends a value to the url using get.

Every time a user selects the drop down on the first form it send to the url and then a SQL query is run to select items from a database which works great for all three forms.

However, the problem I have is when the user goes and re-selects a category from the first form it needs to reset the other two below it and emptying the url parameter for both so it just asks the SQL to select the items from that category again.

Please help

Many thanks
Pete

Hi all

I have a form where there are three fields, category, type, colour. On the top drop down (Category) I need it to reset the form and remove the url parameters when it is selected. Here's my code:

<form id="filter" name="filter" method="get" action="product.php">
     
      <br /><strong>Categories:</strong><br /><br />
      <select name="category" id="category_filter" style="width: 200px" onChange="this.form.submit();">
         <option value="0" selected class="meter-calc-text">All Categories</option>
         <?php
         
         $fetchcategories=mysql_query("SELECT * FROM `product_categories` ORDER BY id ASC");
          while($returnedcategories=mysql_fetch_array($fetchcategories)) {
          echo "<option value=\"".$returnedcategories['id']."\"".(($returnedcategories['id']==$_GET['category']) ? ' selected="selected"':'').">".$returnedcategories['name']."</option>"; 
         }
         ?>
         </select>

How do I reset the url when the user clicks the drop down?

Many thanks for your help

I have a session variable called $_SESSION['patchurl'] in a php file , if i get in to an else statement this session variable gets set and i go to http://yyy page.

below is the snippet of the code

<?php
session_start();
?>
<?php
echo '<script type="text/javascript">' . "\n";
if(isset($_SESSION["Email"])){
echo 'window.location="http://www.xxx";';
}
else{
$_SESSION['patchurl'] = "true";
echo 'window.location="http://yyy";';
}
echo '</script>';?>

once the patchurl session variable is set i call a php file which sets an other session variable called $_SESSION["Email"]. now what happens is the $_SESSION['patchurl'] is gone and ONLY the $_SESSION["Email"] is accessible ...can i not set two session variables? why does creating a new session varible overwrites an other one even though they are called different ? am i doing something wrong ?
