(isset(..)) gives wrong results!!!!!

[Sun Zaza]

Hi,
I have an little issue:

I have a 1 foto, fotoYES.jpg in the folder foto on my gallery.

On the php page I use this code:

Code: [Select]

$fotoYES = $site_sess->url("http://www.website.com/foto/fotoYES.jpg");
$fotoNO = $site_sess->url("http://www.website.com/foto/fotoNO.jpg");

$painFOTO = $site_sess->url("http://www.website.com/foto/spainFOTO.jpg"); //This foto DOES NOT EXIST

$foto = (isset($painFOTO)) ? $fotoYES : $fotoNO;
That means if spainFOTO.jpg exist, the result will be $fotoYES, OTHERWISE $fotoNO.

I don't understand why the result always $fotoYES even spainFOTO.jpg not in the folder foto.

I think I should use another code instead of (isset(....)) ? ..:...;

NOTE: http://www.website.com/foto/spainFOTO.jpg give an 404 error! (spainFOTO.jpg does not exist in the folder foto)

Any help will be great,
Cruxy

I think that the request is very clear. So I do not have to post the hole code.

Please if you read goed the post you will understand what I mean.

I think that the request is very clear. So I do not have to post the hole code.

If I ask - is very clear for request ?

[Sun Zaza]

oK no problem. I will explain and feel free to ask me if you need more information or explaination.

I can not post here the hole code of details (it is very big). That why I made for you onother example.

In a custom page I want some information from the table EVENTS.
On events.php you find als results the information of the events + the foto of this events.
Because not all the events has a foto I used the FUNCTION ISSET to show a thumb (thumb.jpg) if the events has a foto or show the thumb (thumb_no) if the events has no foto.

I use this code on the events.php:

Code: [Select]

$events_thumb = "<a href=\"".$site_sess->url(ROOT_PATH."events".$events_row['events_id']).".php \" target=\"_blank\"><img src=\"".$site_sess->url(ROOT_PATH."images/events/thumb".$events_row['events_id']).".jpg\" width=\"120\" height=\"80\" border=\"0\" alt=\"".$events_row['events_name']."\" />";
   
       $events_thumb_no = "<a href=\"".$site_sess->url(ROOT_PATH."events".$events_row['events_id']).".php \" target=\"_blank\"><img src=\"".$site_sess->url(ROOT_PATH."images/events/geen_thumb.jpg")."\") width=\"120\" height=\"80\" border=\"0\" alt=\"".$events_row['events_name']."\" />";

       $foto_url = $site_sess->url(ROOT_PATH."images/events/thumb".$events_row['events_id']).jpg;
       
       $thumb = (isset($foto_url)) ? $events_thumb : $events_thumb_no;


NOTE: $foto_url IS NOT STORED in database (table events), otherwise it will be easy to solve this problem.

Here is the code of the events.php:

Code: [Select]

<?php
$main_template = substr(($_SERVER['PHP_SELF']),0,7);


define('GET_CACHES', 1);
define('ROOT_PATH', './');
include(ROOT_PATH.'global.php');

$allowed_users_access_page = array(substr(($_SERVER['PHP_SELF']),8,-4)); // Change for all user ID need.
if (function_exists('check_for_valid_user_access_page') && !check_for_valid_user_access_page($allowed_users_access_page) && $user_info['user_level'] < ADMIN) {
   redirect($url);

?>
So my question is: Why when I use ISSET I get A NOT EXISTING THUMB with the events who has no foto?
I think I have to use here another fuction!!!!!!!

[thunderstrike]

I check code for this:

Code: [Select]

$main_template = substr(($_SERVER['PHP_SELF']),0,7);

I say for no one for use this. Hi risk.

Code: [Select]

$allowed_users_access_page = array(substr(($_SERVER['PHP_SELF']),8,-4)); // Change for all user ID need.

for:

Code: [Select]

$allowed_users_access_page = array(substr($self_url, 8,-4)); // Change for all user ID need.

if use my MOD.

and why two time:

Code: [Select]

$additional_sql = "";
  $additional_sql_array = array();
  if (isset($additional_user_fields) && is_array($additional_user_fields) && !empty($additional_user_fields)) {
      foreach ($additional_user_fields as $key => $val) {
          $additional_sql = ", u." . $key;
          $additional_sql_array[] = $key;
      }
  }
 
  if (isset($additional_user_fields) && is_array($additional_user_fields) && !empty($additional_user_fields)) {
   foreach ($additional_user_fields as $key => $val) {
      $additional_sql .= ", u.".$key;
   }
}

for $additional_sql for additional user fields ?

Code: [Select]

$foto_url = $site_sess->url(ROOT_PATH."images/events/thumb".$events_row['events_id']).jpg;

if use file extension at end of line - use like this:

Code: [Select]

$foto_url = (isset($events_row['events_id'])) ? get_file_extension($events_row['events_id']). ".jpg" : "";

If want to use for URL - use like this:

Code: [Select]

$foto_url = (isset($events_row['events_id'])) ? $site_sess->url(ROOT_PATH . "images/events/thumb" . get_basefile(stripslashes(trim($events_row['events_id']))) . ".jpg" : "";

(Note: I no test - is your file so I think is what you look...)

and why two time:


Code:
$additional_sql = "";
  $additional_sql_array = array();
  if (isset($additional_user_fields) && is_array($additional_user_fields) && !empty($additional_user_fields)) {
      foreach ($additional_user_fields as $key => $val) {
          $additional_sql = ", u." . $key;
          $additional_sql_array[] = $key;
      }
  }

   foreach ($additional_user_fields as $key => $val) {
      $additional_sql .= ", u.".$key;
   }
}

for $additional_sql for additional user fields ?

It is not important. I just used the code of onther file to get some infomation from user table.

If want to use for URL - use like this:


Code:
$foto_url = (isset($events_row['events_id'])) ? $site_sess->url(ROOT_PATH . "images/events/thumb" . get_basefile(stripslashes(trim($events_row['events_id']))) . ".jpg" : "";

Actualy is not what I want. I will change the code to make it easy for you:

Code: [Select]

$foto_url = $site_sess->url(ROOT_PATH."images/events/thumb".$events_row['events_id']).jpg;

$thumb = (isset($foto_url)) ? $lang['foto_yes']: $lang['foto_no'];
Explanation:

I have 2 events: events1 and events2 (1 and 2 are events_id's)

So this line means:

Code: [Select]

$foto_url = $site_sess->url(ROOT_PATH."events/foto".$events_row['events_id']).jpg
$foto_url = http://www.website.com/events/foto1.jpg or /foto2.jpg.

In the folder events I have only foto1.jpg.

So I want that the code look into the folder events and look for foto1.jpg for events1 and foto2.jpg for events2 if exist.
That why I used this code (But I think it is wrong)

Code: [Select]

thumb = (isset($foto_url)) ? $lang['foto_yes']: $lang['foto_no'];
That means:
If foto2.jpg exist for events2 show as results $lang['foto_yes'], otherwise $lang['foto_no'];

Because foto2.jpg does not exist, I expected $lang['foto_no']. My code shows $lang['foto_yes] and this is wrong.

I believe that In this situation I have to use onother code instead the isset code.

Good explanation, he?

Ohh ok - now I get. You need for use loop for load all image file. Is why is no work. If no loop, is no work.

[Sun Zaza]

You are still not understand my request, never mind!!
Thank you anyway for trying helping me!

I hope you or someone else will get the point to solve this little issue!

[thunderstrike]

You are still not understand my request, never mind!!

If so - please post full request . You create topic so you need say problem so people get.

[Sun Zaza]

I explain it more than 3 times with three different ways to make it easy for you.
If you do not want to understand it, just forget it. No problem at all.

[thunderstrike]

If you do not want to understand it, just forget it. No problem at all.

I see no where in topic where I say I no want for understand. Your request is big but code is too small - how I get  :

[Sun Zaza]

I will think about onother way to explain it.
I will get back to you.

Thank you in advance
