$_SESSION['rows'] unsetting upon submit...

billyp1970 · March 18, 2011

Driving myself nuts...can't figure out what is wrong with this code. This is part of a pagination system that uses an array instead of hitting the db each time. I am using CodeLobster PHP version (3.7), Windows 7, and using a virtual server on my computer for development (XAMPP)

the error I get is this:

Warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\website\searchinv.php on line 45

Warning: array_multisort() function.array-multisort: Argument #1 is expected to be an array or a sort flag in C:\xampp\htdocs\website\searchinv.php on line 49

Warning: array_slice() expects parameter 1 to be array, boolean given in C:\xampp\htdocs\website\searchinv.php on line 108

Warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\website\searchinv.php on line 146

I am pasting the code below and point out each of the lines in the warnings above, and will try to clean up some so that it's not too extensive...

Here is the problem: If I click on any of the "page" $_SESSION['rows'] has all the correct information contained in it. However, if I trigger the "re-sort" select option...$_SESSION['rows'] is empty...all my other $_SESSION variables are still there. At first I thought it was an issue with too many "if/ifelse/else" statements or a wrong syntax...so I changed it to a "switch" and traced it closely. I don't see anything wrong. Next I thought it was caused by the JavaScript "onchange" event...so I took that out...and replaced it with just a submit button...same result. I've done a search on the page for EVERY $_SESSION['rows'] and found only 4 and none of them should blank it out...I've been going crazy on this code for 2 days I'm pulling my hair out now...can ANYONE help?

Like I said if I click a "page" button (stored in the $buttons var and printed above)...the code works beautifully...it's when the next lines (below) are triggered that cause $_SESSION['rows'] to be empty...I just don't get it

print_r($_SESSION['rows']);

above line 45 and let me know what it returns please

billyp1970 · March 18, 2011

I placed print_r($_SESSION['rows']); above line 45...and nothing showed up.

After I did that I put print_r($_SESSION); and got the following:

<?php
Array
(
    [count] => 38   // This is a session var used elsewhere 
    [rows] => 
    [pages] => 1  // This one is figured in the script
)
?>

This is the dangest error I have ever encountered...I just don't get it...I'm sure it's something simple...just don't know what.

billyp1970 · March 18, 2011

Additionally for completeness, I also added print_r($_POST); after print_r($_SESSION); and got the following:

<?php
Array
(
    [count] => 38
    [rows] => 
    [pages] => 1
)
Array
(
    [re_sort] => last_update SORT_ASC // Last Update Sorted Ascending 
)
?>

well if you look you have no entry/data in your rows...try giving rows a value then test again

billyp1970 · March 19, 2011

I know $_SESSION['rows'] has no value...that is the problem. Let me see if I can clear this up and you'll see why I'm pulling my hair out.

I have a page called searchinv.php that loads a search form with a POST action. When the form is submitted it is re-directed to the search page which then sees that $_POST is not empty but $_POST['page'] is empty to therefore executes the switch code above. $_POST['ref'] or $_POST['type'] will ALWAYS be set one the first run so the "default" on the switch will NEVER be executed on the first run. If you follow the code down after $_POST['ref'] or $_POST['type'] returns $rows from the database; $_SESSION['rows'] is then set to $rows. Then a table is drawn showing only 20 rows at a time and also a set a buttons at the bottom for page navigation.

The bottom row of buttons is set to a form that is also a post re-directing to the searchinv.php page. The buttons have the name "page" so that this time the page is drawn $_POST is set and so is $_POST['page'] so it skips the switch code and renders the page with the information already contained in $_SESSION['rows']. This works just fine so I know that $_SESSION['rows'] has been set.

At the very bottom of the page below and NOT included in the "button" form is a second form which includes only a dropdown box which allows for a re-sorting of the items in the search. This is where the problem starts. If you decide to re-sort, it is re-directed again to the searchinv.php $_POST is not empty but $_POST['page'] IS EMPTY...so the switch code is activated...$_POST['ref'] and $_POST['type'] are both empty, so the default on the switch is executed. $data is then set to $_SESSION['rows']...which has somehow emptied itself!

Because $data is empty becuase $_SESSION['rows'] is empty, the abundance of errors occurs. My issue...I can't for the life of me see how/why $_SESSION['rows'] drops all of it's data...

I'll repost the code with better alignment...

Quick update...

I have done a search on EVERY page of my website...using my PHP Editor...there are only 4 occurrences of $_SESSION['rows'] on my site...all located in the code above...so there is NO reason I can see that $_SESSION['rows'] should become unset.

Something else I found interesting...I place print_r($_SESSION['rows']) at the very bottom of my code and checked it BEFORE I re-submitted a resort...and $_SESSION['rows'] is there with the information...so why when I submit does it disappear?

I also ran a validation on the code...I found some errors...fixed them and same result...grrr

try echoing $rows after its been defined and see if you get a value...there' something obviously wrong at the top of the code but i cant see what

billyp1970 · March 20, 2011

After more extensive troubleshooting...I've narrowed the problem to this bit of code...

<?php
              default: 
                  $data=$_SESSION['rows'];
                  $sorts=explode(' ',$_POST['order']);
                  $keys=$sorts[0];
                  $order=$sorts[1]; print_r($data);
                  foreach($data as $key=>$row)
                    {
                      $column[$key]=$row[$keys];
                    }
                  $rows=array_multisort($column,$order,$data);
                  break;
?>

print_r($data) shows that $_SESSION['rows'] is passing it's contents so the issue falls with the 'foreach' statment...

after that everything breaks because then this $rows is empty which in the next set of lines gets set to $_SESSION['rows']...

billyp1970 · March 20, 2011

Ok I think I figured it out...

<?php
array_multisort($sort, $order, $data);
?>

the order has to be hard coded...you can not place a var there because if you do you get Warning: array_multisort(): Argument #2 is expected to be an array or a sort flag...this just caused a plethora of errors...so now I'll place another switch statement to figure which way to sort...

billyp1970 · March 20, 2011

I still don't get what is wrong...I completely re-wrote the code and decided to just query the database each time a change is made...

submit your new code and i'll have a good look over it

$_SESSION['rows'] unsetting upon submit...
