PHP - Check If Multiple Variables Are Set

Hello everyone, I'm sitting here in a position where I can't work on my site or test any code, but my mind is racing about what I can do to solve a particular problem that I have.  I won't get into the problem because it would take more time to type than I have right now, but I have an idea for a simple solution, just not sure if it will work or not.  So, here's my question: Is it possible to have multiple session variables during a session?

Such as:
$email=$_SESSION['email'];
$user=$_SESSION['userid'];

If this is possible, my problem is solved (I think)... otherwise, I have to keep thinking about it.  Thanks for any help!

Hi,

I'm having a bit of a problem sharing some variables I have across a few files.

My first file (index.php) calls an ajax request for (display.php) and sends a few variables to it. All fine so far. display.php then does its thing and displays the content on index.php as it should. Now in display.php I need a variable to be passed back to index.php for use in a menu.
I've tried setting a session variable in display.php but unfortunately this doesn't seem to work. I also can't use get or post as I don't want to refresh the page.

Really scratching my head over this one!

Hi, I want to send the following variable using the $_GET function:

hello, im wondering how to properly code the following.

Code: [Select]
$stdate = date( 'Ymd', strtotime($pdate) );
$sttime = date( 'His', strtotime($tstart1) );

$dtStart = ".$stdate.'T'.$sttime.'Z'";

echo "$dtStart";

i would like the echo to read 20110309T050000Z

I have this function:
Code: [Select]
function echo_exist($pre1,$ee,$post1) {
if ($ee!='') {
return $pre1;
return $ee;
return $post1;
}
else {
//do nothing
}
}
But when I try to echo it
Code: [Select]
echo_exist("(","$row['payment_type']",")");
I get syntax error, unexpected T_ENCAPSED_AND_WHITESPACE
If $row['payment_type'] exists, I want it to be displayed in parentheses like:  (AUTO)

I suspect it has to do with my ' characters for the associative array, but I am new with functions so perhaps it is the multiple arguments that are wrong?

Hello need some help

Hi all, i've got a string ($currentcatid) which contains one number which changes dependant on which page the visitor is on.. ie  it may be perhaps "23" or "17" .

I need to do a check against this string to see if it contains any of the following values .. 31,32, 1, 24 . I cant remember how i did it before but i think it was with pipes..

something along the lines of
if ($currentcatid =="31"||"32"||"1"||"24") { action }

can anyone help?

Thanks

When a user logs into my site I was to store the user_name, user_role, and user_id in a session variable, then store this in a regular variable to make querying easier, but I am having issues with my code as its causing issues with my queries.

Code: [Select]

if (mysqli_num_rows($data) > 0) {
  //set sessions
    $row = mysqli_fetch_array($data);
    $_SESSION['username'] = $row['username'];
    $_SESSION['user_role'] = $row['role'];
    $_SESSION['user_id'] = $row['user_id'];
         
           
  //set variables
    $username = $_SESSION['username'];
    $user_role = $_SESSION['user_role'];
    $user_id = $_SESSION['user_id'];

}


Any ideas whats wrong?!
Thanks for the help!!

Hi Guys and Girls,

Long time lurker, first time poster!

I am usually able to read through the forums and find and answer without having to start a new thread but I've tried my best to no avail.

I am having trouble with the following code:
$afname="Gareth";
$alname="B";
$awayoption.="<OPTION VALUE=\"".$afname." \"".$alname."\">".$afname."&nbsp;".$alname;

I would want that to produce the following:

Code: [Select]
<OPTION VALUE=Gareth B">Gareth B
The actual result at the moment is:

Code: [Select]
<OPTION VALUE="Gareth "B">Gareth&nbsp;B
It has an extra " in the middle. Any ides or help would be great!

Cheers

    I have a webpage that I am working on that is now in construction mode. The url is: https://localbizseek.com/lbs/index6  The problem is that I want to it to be able to search 2 at the same time in the phpmyadmin database table which is named "places".  I also want to be able to get to search all 9 cities for that area.  There are a total of 36,000+ cities in the database.  However, I want it to be able to search just 2 or 9 specific cities of those cities.  Each city has a city_id which is an integer assigned to it in the database  Right now it will search only 1 city at a time or it will search every city in the database if I assign the search variable as "" or "0".  I don't know what to do on this page to solve it and on the related processing page.  Here is the code on the webpage:
   
              

        <form id="main-search-form" method="GET" action="<?= $baseurl; ?>/_searchresults.php" role="search">
         
        
        <select id="query-input" name="city_id" style="width:28.8%" style="height:69px" required>
                        
        <option value="">Select Area</option>
             
        <option value="3;1">Ches & VB</option>
        <option value="3">Chesapeake , VA</option>
        <option value="9">Hampton , VA</option> 
        <option value="10">Newport News , VA</option>   
        <option value="2">Norfolk , VA</option>   
        <option value="12">Poquoson , VA</option> 
        <option value="4">Portsmouth , VA</option>    
        <option value="5">Suffolk , VA</option>    
        <option value="1">Virginia Beach , VA</option> 
        <option value="11">Williamsburg , VA</option>
        <option value="0">All Active US Cities</option>
        </select>
        </form>

    You will notice that I have tried "3;1" up under the Ches & VB Select Option but that doesn't work because it will not work that way.  I can have it as "3 1" but then it just displays 1 which is VB's information.  I've tried everything possible and it won't search both variables.  It only will search one.
   
    So I'm thinking I need to do something at both ends on the code.  Here is the other end of the code which is the results processing page.  Note that there is also a third page of code which is the template page which I will add next:
   
             

      <form id="main-search-form" method="GET" action="<?= $baseurl; ?>/_searchresults.php" role="search">
         
        
          <select id="query-input" name="city_id" style="width:28.8%" style="height:69px" required>
                        
              <option value="">Select Area</option>
             
              <option value="3,1">Ches & VB</option>
              <option value="3">Chesapeake , VA</option>
        <option value="9">Hampton , VA</option> 
        <option value="10">Newport News , VA</option>   
        <option value="2">Norfolk , VA</option>   
        <option value="12">Poquoson , VA</option> 
        <option value="4">Portsmouth , VA</option>    
                    <option value="5">Suffolk , VA</option>    
                    <option value="1">Virginia Beach , VA</option> 
        <option value="11">Williamsburg , VA</option>
                    <option value="0">All Active US Cities</option>
   
      
           
        </select>

    Here is the final page of code which I'm not sure if this one needs changing but just in case here it is:

I am creating a webpage for my golf league and some of the information(variables) such as Name, Address and email, must be reused across multiple pages for different outputs.  May question is "Can I, or is there a way to reUse variables across multiple pages.   "Do I need to create a session and make everything session variables"?  "Should I link to a database and call the information when needed"? 

Any explanation would be greatly appreciated. 

hello i have built a webpage using tables.
i might have done something wrong (except using tables) and now the results are rendered chaotically on the webpage. also here is the attached file. after the 4th article it's all messy

i have a solution but that means to insert a php tag inside another php tag, but won't work

thankyou

This will only send 1 goggles information into the database but I have a "adding" page that can actually add more than 1 goggles at once. I have no idea how to go about  saving multiple goggle's information using array or loop.


$name= $_POST['goggles_name'];
$price = $_POST['goggles_price'];
$des = $_POST['goggles_description'];
$file = $_FILES['goggles_image']['name'];
$chkbox = $_POST['upload'];
$id = $_POST['goggles_id'];
 

$query = "UPDATE goggles SET goggles_name = '$name' , goggles_price = '$price' ,goggles_description = '$des' WHERE goggles_id ='".$id."' "; 
$result = mysqli_query($link, $query) or die(mysqli_error($link));

Hi,

I have an affiliate system that shows results on what product is purchased. The problem is that the tracker is only listing the first product in the purchase list, so if someone purchases multiple products it only shows the first product in the transaction report. 

Here is the code:

Code: [Select]
$module = fetchDbConfig('PostAffiliatePro');

$orderInv = $order->getOrderInv($_GET["cart_order_id"]);

print_r($orderInv);

$affCode = "<!-- Begin PostAffiliatePro Affiliate Tracker -->
<img border='0' src='".$module['URL']."/scripts/sale.php?TotalCost=".sprintf("%.2f", $orderSum['subtotal'])."&OrderID=".$cart_order_id."&ProductID=".$orderInv['0']['productCode']."' width='0' height='0' alt='' />
<!-- End PostAffiliatePro Affiliate Tracker -->";


?>
The code I need help with syntax is:
Code: [Select]
"&ProductID=".$orderInv['0']['productCode']."The products are split into arrays by number (0,1,2,3). So for example, I would want to show results for .$orderInv['0']['productCode'].  , then .$orderInv['1']['productCode'].  , and so on.

 I would like the results to be posted with a ; between them, but I don't know the proper syntax to have it report more than just the first array. This seems pretty simple, but I only know the basics of PHP and I've adapted this from found code. 


Any guidance would be greatly appreciated.  Thanks!
