Hm... Try this:

<?php

/* Look into the directory and returns the folders
   (country/states)
   */
    $country = "Researchers/";
    if (is_dir($country)
   {
    $varstate = opendir($country);
       while (false !== ($folder = readdir($varstate))) {
       
/* list only subdirectories first

if ($folder != "." && $folder != "..") {
                    echo "<a class=\"item2 arrow\" href=\"javascript:void(0)\">$folder <img src=\"images/arrow1.gif\" width=\"10\" height=\"12\" alt=\"»\" /></a>";
                              $state = "$varstate";
                              if (is_dir($country.$state)) // add a slash to directories

                              {

                                   $tmp = ($country.$state .= "/");

                              }

Result:
Warning: readdir(): supplied argument is not a valid Directory resource in /home/www/inc/researchers_menu.inc on line 32

yeah, I thought of that too...

A little more info.

I am running a java script to create a drop down menu on a php page.

With out this script I have to add in manually to the menu.inc each bio page url for each researcher, and what country / state they are in.

So instead I tried to create a php script that would do it for me.

The script is suppose to goto the top level directory called Reseachers (also the first tag in the drop down menu) create a sub menu listing from each directory (which are called Canada, USA etc) then list the file names in each state menu (i was going to add the remove suffix of file type later)

In the original, manually add by hand menu the format is this:
        <td>

            <a class="item1" href="javascript:void(0)">Researchers</a>

            <div class="section">

                <a class="item2 arrow" href="javascript:void(0)">Canada  <img src="images/arrow1.gif" width="10" height="12" alt="»" /></a>
                      <div class="section">
                <a class="item2 arrow" href="javascript:void(0)">British_Columbia  <img src="images/arrow1.gif" width="10" height="12" alt="»" /></a>
                  
                <div class="section">
                            <a class="item2" href="./index.php?page=r01">John Doe (Vancouver, BC)</a>
                                  

                </div>

            </div>

        </td>

*EOP (end of part)

What I want to do is replace this with a script that will do it for me.
BTW "r01" is the content of the John_Doe.bio file (a cheating redirect)

 

by: ZylochPosted on 2005-12-01 at 15:26:55ID: 15401110

Is it possible for you to systematically comment out part of the code and put strategic echo/die statements to get more information, as that's what I would do.

One of the things to do may be to make sure that each directory exists (putting echo statements inside if clauses and commenting out the rest temporarily) and also try echoing out $tmp to make sure that is correct.

 

by: ALEx604Posted on 2005-12-01 at 15:33:42ID: 15401197

I just suck at while loops in php.

I have never figured out how to put a while out inside another while loop.

However, taking you advice I did the following which might be a clue.

I add the line..

echo "FOOBAR $tmp FOOBAR";

Just above where biopages is set.

the result is "FOOBAR FOOBAR"

So $tmp isn't getting set at all, it's null.

 

by: ALEx604Posted on 2005-12-01 at 15:36:53ID: 15401250

Heh, niether did country or state!
echo "FOOBAR $country $state FOOBAR";
results in...

FOOBAR Researchers Resource id #7 FOOBAR

 

by: ALEx604Posted on 2005-12-01 at 15:41:13ID: 15401286

Actually country must have worked because that part of the menu appears. So maybe I have totally assumed some basics things here.

there are two folders under reseachers (Canada and USA) they both appear in the menu as they should. But British columbia and ohio do not appear, as sub menu tags, nor the john doe  and james doe bio files etc

 

by: ZylochPosted on 2005-12-01 at 15:45:24ID: 15401330

I tidied it up a bit, used single quotes when possible to speed ups script and changed a few variables around. Try this:

<?php

/* Look into the directory and returns the folders
   (country/states)
*/

$country = "Researchers/";
if (is_dir($country))
{
    $varstate = opendir($country);
    while (false !== ($state = readdir($varstate)))
    {
        /* list only subdirectories first
           let's skip the first two folders (. & ..)
        */

        if ($state != "." && $state != "..")
        {
            echo '<a class="item2 arrow" href="javascript:void(0);">' . $state . ' <img src="images/arrow1.gif" width="10" height="12" alt="»" /></a>';

            $new_path = $country . $state;
            if (is_dir($new_path)) // add a slash to directories
            {
                $biopages = opendir($new_path . '/');
                while (false !== ($file = readdir($biopages)))
                {
                     echo '<a class="item2" href="';
                     echo "$country/$state/$file";
                     echo "\">$file</a>";
                }

                closedir($biopages);
            }      
        }
    }

    closedir($varstate);
}
         
//Close Select
?>

Let's see if I can describe this.
Result:

Researchers
USA >>
.
..
Ohio
Canada
.
..
British Columbia

This comes as you see it above. Not as a menu which when clicked on Canada, then British Columbia appears, then if you click on BC you get a list of names.

by: ZylochPosted on 2005-12-01 at 16:14:13ID: 15401523

I'm a bit confused. Where's the loop you use to loop through countries? Is my code kind of on the right track with the changed variable names and all?

 

by: ALEx604Posted on 2005-12-01 at 16:42:13ID: 15401632

Yeah, let's make this easier....
Researcher-test your code

(044 is blank page)

 

by: ZylochPosted on 2005-12-01 at 16:59:28ID: 15401714

I see. Let me assume you want to look up countries as well. Then:

<?php

/* Look into the directory and returns the folders
   (country/states)
*/

$main_folder = "Researchers/";
if (is_dir($main_folder))
{
    $varstate = opendir($main_folder);
    while (false !== ($country = readdir($varstate)))
    {
        /* list only subdirectories first
           let's skip the first two folders (. & ..)
        */

        if ($country != '.' && $country != '..')
        {
            echo '<a class="item2 arrow" href="javascript:void(0);">' . $country . ' <img src="images/arrow1.gif" width="10" height="12" alt="»" /></a>\n<div class="section">';

            $new_path = $main_folder . $country;
            if (is_dir($new_path)) // add a slash to directories
            {
                $this_country = opendir($new_path . '/');
                while (false !== ($state = readdir($this_country)))
                {
                    if ($state != '.' && $state != '..')
                    {
                        echo '<a class="item2 arrow" href="javascript:void(0);">' . $state . '<img src="images/arrow1.gif" width="10" height="12" alt="»" /></a>\n<div class="section">';

                        $second_new_path = $new_path . $state;
                        if (is_dir($second_new_path))
                        {
                            $biopages = opendir($second_new_path . '/');
                            while (false !== ($file = readdir($biopages)))
                            {
                                if (!is_dir($file))
                                {
                                    echo '<a class="item2" href="';
                                    echo "$country/$state/$file";
                                    echo "\">$file</a>";
                                }
                            }

                            closedir($biopages);
                        }

                        echo '</div>';
                    }
                }

                closedir($this_country);
            }

            echo '</div>';      
        }
    }

    closedir($varstate);
}
         
//Close Select
?>

 

by: ALEx604Posted on 2005-12-01 at 17:33:14ID: 15401870

Almost! :)
the only thing not showing up is the file name.

(I removed the "\n"'s )
_________
readdir($biopages)))
                            {
                                if (!is_dir($file))
                                {
                                    echo '<a class="item2" href="';

There is also the point of content redirect, which I just added to yours.


readdir($biopages)))
                            {
                                if (!is_dir($file))
                                {
                                    echo '<a class="item2" href="';
$redirect = fread(fopen($file, "r"), filesize($file), 1);
fclose($file);
                                    echo "$country/$state/$redirectfile";
                                    echo "\">$file</a>";
                                }
                            }

                            closedir($biopages);

__________

Which didn't help much :( :)

 

by: ZylochPosted on 2005-12-01 at 17:36:38ID: 15401879

I'm not too sure what you're trying to do with the last bit of code and the $redirect

 

by: ALEx604Posted on 2005-12-01 at 17:45:45ID: 15401921

the redirect is not important

I added a few more folders in the directory, and states and bios for testing.

The countries, and states work great, but it is not listing the bio files.

 

by: ZylochPosted on 2005-12-01 at 17:50:18ID: 15401939

Try:

                                if (!is_dir($second_new_path . '/' . $file))
                                {
                                    echo '<a class="item2" href="';
                                    echo "$country/$state/$file";
                                    echo "\">$file</a>";
                                }

 

by: ALEx604Posted on 2005-12-01 at 18:00:58ID: 15401974

Dang. no.

I hate getting this close.

I'm going to increase the points for this. (When I have some) then award it to you.

Have a look at the source code of the page, as it is generated by the script on the URL above.
in part:
