Read Directory Contents into an Array

EmpireLost

I am working on am news script for fun, and i want the user to be able to associate an image with the news post. I am trying to put a preview of the image selected on the form page. The page will read the contents of an image directory and put the names in a drop-down options box. When an image is selected in the box i want a preview of the image to show on the page. There is no upload option cause i dont want one.

Now to the question. How can i read the file names in the specified directory into a numerically indexed array?

I will then take the number associated with the selected image and send it to a preview function for display. If you need to see my code then just ask for it and i will post it.

Thx.

See example 2 under opendir().

I have tried several of the examples under opendir() and readdir() but none of them work. I always get an Undefined offset error and the images dont display when i select them.

For an example: Yabb SE Profile page -
On this page you can select a "Personalized Picture" for yourself. It has a textarea with the contents of the avatars directory listed in it. When you click one of the names in the list a preview appears next to the list.

That is essentially what i want to happen but i can't understand Yabb's way of doing it and i would like to simplify it for my needs. Instead of the textarea im using the drop-down options box but i want the same thing to happen as Yabb's.

Thx

do a searh for "opendir()" "readdir"....

maybe even $d = opendir($dir);

you'll find a post from yesterday or the day before where someone asked the EXACT same question practically....

Sounds like you have a whole other problem then since the well-tested opendir function isn't doing what you want.

Maybe check a YaBB support forum or make it clear that you are trying to hack some functionality into YaBB?

Fine...I'll hand hold this one:

// get the contents of the specified directory and save to object
$directory = dir("./yourdir");

// update the table with the updated file information
while ($entry = $directory->read()) {
$file_array['name'] = $entry;
}

You could get even more complex and store all the file details as well into an array like this:

// get the contents of the specified directory and save to object
$directory = dir("./yourdir");

// update the table with the updated file information
while ($entry = $directory->read()) {
$filecount++;
$file_array[$filecount]['name'] = $entry;
$last_fullstop_position = strrpos ($entry, ".");
$file_array[$filecount]['type'] = $type;
$file_array[$filecount]['base'] = substr ($entry, 0, $last_fullstop_position);
if ( $file_array[$filecount]['base'] != ".." || $file_array[$filecount]['base'] != ".") { $file_array[$filecount]['ext'] = substr (strrchr ($entry, "."), 1); } else { $file_array[$filecount]['ext'] = ""; }
$file_array[$filecount]['size'] = filesize("." . $HTTP_GET_VARS['dir'] . "/" . $entry);
$file_array[$filecount]['modified'] = date("Y-m-d G:i:s", filectime("." . $HTTP_GET_VARS['dir'] . "/" . $entry));
$file_array[$filecount]['length'] = strlen ($entry);
}

To get the values from the 'complex' array, use a FOR construct:

for ($i=1; $filecount >= $i; $i++) {
echo $filearray[$i][name];
...
}
