help with listing folders and files

[irkevin]

Hi,

 

basically I have one folder[A] with several folders in it.. and in those several folders i have some files..

 

So what i want is, have a drop down which list all folders in folder[A].... Luckily for me I've been able to do this..

 

Now, once i select a folder in the dropdown, i want another dropdown to appear with the files in this folder.. Hope that makes sense.. Ask me, i'll elaborate.. here is the code i have so far

 

<?php

// define the path as relative

$path = "./manga/";

// using the opendir function

$dir_handle = @opendir($path) or die("Unable to open $path");

echo "<select id='choose' onchange='selectManga()'>";
echo "<option>Choose a manga</option>";
// running the while loop
	while ($file = readdir($dir_handle))
	{

		if($file == '.' || $file == '..')
		{
			//
		}
		else
		{	

			echo '<option value="'.$path.$file.'" name="'.$file.'">'.$file.'</option>';
			$your_file = 'manga/'.$file;
		}


	}

	echo "</select>";



closedir($dir_handle);

?>

 

Well now i need some help guys

[samona]

You would probably need javascript for that.

[Yesideez]

If you don't want to reload the page when the first drop-down is changed then Javascript is the answer.

[irkevin]

Ok correct for javascript.. but how do i list all files in the selected folder in the dropdown then?

 

 

[irkevin]

I tried this but i doesn't even list something..

 

 

<?php

// define the path as relative

$path = "./manga/";

// using the opendir function

$dir_handle = @opendir($path) or die("Unable to open $path");

echo "<select id='choose' onchange='selectManga()'>";
echo "<option>Choose a manga</option>";
// running the while loop
	while ($file = readdir($dir_handle))
	{

		if($file == '.' || $file == '..')
		{
			//
		}
		else
		{	
			echo '<option value="'.$path.$file.'" name="'.$file.'">'.$file.'</option>';
			$your_file .= $path.$file.'/';
		}

	}

	echo "</select>";



closedir($dir_handle);

$chapter = $your_file;

$chapter_handle = @opendir($chapter) or die("Unable to open $chapter");

//echo "<select id='choose_chap' onchange='selectChap()'>";
//echo "<option>Choose a Chapter</option>";

while ($chapter_file = readdir($chapter_handle))
{
	echo $chapter_file;	
}
//echo "</select>";
closedir($chapter_handle);
?>

 

Any ideas guys?

[Yesideez]

You getting ANYTHING in the dropdown? Even emptyness?

[irkevin]

in the first dropdown yes, it's listing all the folders, but im getting a hard time to list files in selected folders .....

[Yesideez]

I've had a pay with the code...

<?php

// define the path as relative

  $path = "./manga/";

// using the opendir function

  if ($dir_handle = @opendir($path)) {

    echo "<select id='choose' onchange='selectManga()'>";
    echo "<option>Choose a manga</option>";
    // running the while loop
    while (($file = readdir($dir_handle)) !== false) {

       if ($file != '.' && $file != '..') {   
          echo '<option value="'.$path.$file.'" name="'.$file.'">'.$file.'</option>';
          $your_file .= $path.$file.'/';
       }
       
    }

    echo "</select>";
     
    closedir($dir_handle);

    $chapter = $your_file;
     
    if ($chapter_handle = @opendir($chapter)) {

      //echo "<select id='choose_chap' onchange='selectChap()'>";
      //echo "<option>Choose a Chapter</option>";

      while ($chapter_file = readdir($chapter_handle)) {
        echo $chapter_file;
      }
      //echo "</select>";
      closedir($chapter_handle);
    } else {
      echo "Unable to open $chapter";
    }
  } else {
    echo "Unable to open $path";
  }
?>

[irkevin]

i tried your code and it says unable to open

 

Unable to open ./manga/first_directory/

 

but the dropdown to list the current existing folders works fine..

 

[Yesideez]

If it says it's unable to open then there's one error for you already - you need to be able to open a folder before the script will run through.

[irkevin]

huh? what do you mean?

[samona]

I think he's talking about permissions.

[irkevin]

im testing this locally.. :S

 

Well, if i change this :

 

$chapter = $your_file;

to

$chapter = "./manga/first_directory/";

 

then it works.. but i have other folders in the folder manga ...

[samona]

im testing this locally.. :S

 

Well, if i change this :

 

$chapter = $your_file;

to

$chapter = "./manga/first_directory/";

 

then it works.. but i have other folders in the folder manga ...

 

how about $your_file = "./manga/first_directory/";

$chapter = $your_file;

[irkevin]

ok in the folder there is 'first_directory', 'second_directory'

 

what if i want to choose the second one?

[irkevin]

bump no one?

[irkevin]

I noticed that, when i removed the '.' here

 

$your_file .= $path.$file.'/';

 

and change it to

 

$your_file = $path.$file.'/';

...

 

it works. but i read only one folder :S.... how can i switch to the other one :S

[irkevin]

no one to help? 

[Yesideez]

I'm surprised this hasn't been solved yet.

 

When I get home from work I'll post source I've got on my HD somewhere to scan a web server displaying files and folders with nice little icons.

[irkevin]

Ok man and thanks for your help i'll be waiting

[Yesideez]

It won't be for about 6 hour yet but even if this is solved I'll post it. I'll PM you either way to let you know I've posted it.

[irkevin]

Here's what i've been looking for

Looks like i'm almost done with it..

 

here is the code

I know it might look messy to you guys I'm only good with php and mysql.. and it the first time i've been able to manage something with folders, subfolders and files..

 

Below is the javascript to get the dropdown to go to the selected folders and Files..

 

<script type="text/javascript">


<?php echo $jsarray;?>
<?php echo $gallery;?>

var curimg = 0


function rotateimages()
{

document.getElementById("slideshow").setAttribute("src", "<?php echo $chapter;?>/"+galleryarray[curimg])


document.getElementById('page').options[curimg+1].setAttribute('selected','selected');



if(curimg < galleryarray.length-1)
{
	curimg = curimg+1;
}
else
{
	curimg = 0;
	document.getElementById("slideshow").style.cursor = 'default';
}
}


function selectManga()
{
var folder = document.getElementById('choose');

for(i=0;i < folder.selectedIndex; i++)
{
	if(folder.selectedIndex)
	{
		document.location = folder.value;
	}	
}	
}

function selectChapter()
{
var chapter = document.getElementById('chapters');

for(i=0; i < chapter.selectedIndex; i++)
{
	if(chapter.selectedIndex)
	{
		document.location = chapter.value;
	}
}
}

function changePage()
{
var MyPage = document.getElementById('page');

for(i=0; i < MyPage.selectedIndex; i++)
{
	if(MyPage.selectedIndex)
	{
		document.getElementById('slideshow').src = MyPage.value;		
	}
}
}

</script>

 

Oh, if you have some modification that would make the script better, do share plz ..
