PHP - Unlink Files In A Directory

Hi guys,
I am using a MySQL table to store if a user has access permisisons to a file.

The files are stored outside the webdirectory in drive F:\

So I have this code I have been playing around with in order to display the file I access and check permissions for:
<?php
$file = $_GET['file'];

$myfile = 'F:\files\/'.$file.'.jpg';

echo "<img src='$myfile' />";
?>


So a sample case would be say on index.php
<img src="http://somedomain.com/files?file=abcdefghijkl" />
and only if the current user had permissions to view that file would they see it.

Any help on how I can do this is greatly appreciated.

I do understand all my above code is probably totally wrong.

Cheers

I almost have it but can't figure why the code below only shows one file per folder.

I think it is showing the last file.

I need $ul somehow looping to show all the files in $file.


<?php
$year = date('Y');

if ($handle = opendir("results/$year/Boys")) {

while (false !== ($file = readdir($handle))) {

if ($file != "." && $file != "..") {

if ($handle2 = opendir("results/$year/Boys/$file")) {

while (false !== ($file2 = readdir($handle2))) {

if ($file2 != "." && $file2 != "..") {
$ul = "<li><a href=\"#\">$file2</a></li>";

$li =  "<li><a target=\"_blank\" href=\"javascript:void(0)\">$file</a>
<ul>
$ul
</ul>
</li>";

} // close if file2
}echo $li;
}
}
}
}closedir($handle);closedir($handle2);
?>

I am trying to find a script that will show just the file names of files in a specific directory.
I tried this code posted previously on this forum and it works but shows the directory name.
Code: [Select]
<?php
filesInDir('attachments');
function filesInDir($tdir)
{
        $dirs = scandir($tdir);
        foreach($dirs as $file)
        {
                if (($file == '.')||($file == '..'))
                {
                }
                elseif (is_dir($tdir.'/'.$file))
                {
                        filesInDir($tdir.'/'.$file);
                }
                else
                {
                        echo $tdir.'/'.$file."<br>";
                }
        }
}
?>
Result is: attachments/Sedona_and_Slot_Canyon_links.docx
Thanks for the help.

I am using the following code to list mp3 files from a directory and find out if there is a file for it in mysql if so not to include it in the list. The code below is listing each file twice I only would like them to be listed once.



if($_POST['submit'] != 'select') {
echo'Choose an mp3 to add information.<p><select name="file">';
$dir = "/uploads/";

$result = mysql_query("SELECT * FROM dj_pool") or die(mysql_error());
$num_rows = mysql_num_rows($result);

// Open a known directory, and proceed to read its contents
if (is_dir($dir)) {
    if ($dh = opendir($dir)) {
        while (($file = readdir($dh)) !== false) {
            $info = explode(".", $file);
            if($info[1] == "mp3") {
            $i = 0; 
            while ($i < $num_rows)
              {
        $file2 = mysql_result($result,$i,mp3);
                if ($file != $file2) { echo "<option value='$info[0]'>$info[0]</option>"; }
            $i++; 
              }
                              }
        }closedir($dh);}
        
    }

print "</select><p><input type=submit value=select name=submit>";

I have a function that reads all the picture files in a folder and displays them as thumbnails. It also displays a large version of the first image in the folder and clicking the thumbnail changes the large picture. I'm trying to use pictures of arrows as a button to allow users to click and have the next picture displayed large rather than having to click each individual thumbnail but don't really know how to get started. Can anyone suggest a method or give me a hint?

This is my code so far if that helps:


function displayPhotos(){

global $columns,$dir,$album;

generateThumbnails();

$act = 0;
$keyid = 0;

$thumb_selected = (isset($_GET['thumb']) ? $_GET['thumb']:'');

if ($thumb_selected !==""){

$dirName  = substr($thumb_selected,0,strpos($thumb_selected,basename($thumb_selected)));
       $thumbName = basename($thumb_selected);
$thumbFile = $dirName.$thumbName;
$large = str_replace('_th.jpg','.jpg',$thumbFile);
}

else{

$picture_array = glob("$dir*");

$large = $picture_array[$keyid];
}

echo "<tr><td colspan='3' height='300' width='400' align='center'><img src='$large' alt=''></td></tr>
<tr><td><img src='gallery/icons/arrow-blue-rounded-left.jpg' alt='Previous'></td><td></td><td align='right'><img src='gallery/icons/arrow-blue-rounded-right.jpg' alt='Next'>
        </td></tr><tr><td height='50'></td></tr>";

if ($handle = opendir("$dir")) {

while (false !== ($file = readdir($handle)))  {

$file=$dir.$file;

if (is_file($file)){

       if (strpos($file,'_th.jpg')){

++$act;

if ($act > $columns) {

echo "</tr><tr><td width='160' height='120' align='center'><a href='?album=$album&amp;thumb=$file'><img src='".$file."' alt='".$file."'/></a></td>";

$act = 1;

} else {

echo "<td width='160' height='120' align='center'><a href='?album=$album&amp;thumb=$file'><img src='".$file."' alt='".$file."'/></a></td>";

}    

       }

       }

}

}

}


Thanks very much to anyone having a look at this!

I have a directory full of pictures that I would like to display in a gallery.

Originally I was going to write HTML like this...

	<li>
	    <img src=/photos/img_001.jpg">
	</li>
	

And then simply copy and paste that for the number of photos I have, and then tweak the code to: img_002.jpg, img_003.jpg, and so on.

I guess that is silly considering that I have over 500 photos to display!

How could I use PHP to go to my /photos/ directory, scan all of the files in that directory, and then grab the file name so I could automate this process?

Sorry, but I haven't written PHP in several years so all of this escapes me!  ☹️

Dear sirs,

I need to upload files to FTP and To waste less time, I zip the files, but the problem that since it is Automation it zips with directory - like this  C:/DIR.zip 
in zip file I have a DIR/files....    How to unzip all files to main directory on the server.  Right now if the main dir is  /main/html/  it unzips to /main/html/dir/files
But I need /main/html/files

Thank you.

I have a script that works perfectly, for one type of file extension.

What I want to do now is be able to list all files in a set of file types.

I want to pass the argument to the fileSystem class's loadFiles method like this:


$some_var = $fileSystem->loadFiles(DATA_DIRECTORY, "csv,xls,etc");


Then in the loadFiles method it reads the dir for each file, then test its extension.  If they are of the right type, then push it on the returned array.

Now I am having problems testing if the file's extension is in the array.  If I use


if (strpos(getExt($file),  $array_of_wanted_exts))...


php would match php3..

Does anybody have a better method?

Good day.   I have just written my first php phpexcell file importing into mysql without errors. now my next step is to try and read multiple excell files in a directory " files are same format" and import into mysql.   Heres my code so far.

<?php
$db_host = "localhost";$db_user = "root";$db_pass = "";$db_name ="kk";$db_table = "test";
require '/Classes/PHPExcel.php';
require_once '/Classes/PHPExcel/IOFactory.php';
$objPHPExcel = PHPExcel_IOFactory::load('Amersfoort_WR.xlsx');
foreach ($objPHPExcel->getWorksheetIterator() as $worksheet) 
{
$worksheetTitle     = $worksheet->getTitle();
$highestRow         = $worksheet->getHighestRow(); // e.g. 10
$highestColumn      = $worksheet->getHighestColumn(); // e.g 'F'

$highestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn);
$nrColumns = ord($highestColumn) - 64;
echo "File ".$worksheetTitle." has ";
   echo $nrColumns . ' columns';
   echo ' y ' . $highestRow . ' rows.';
   echo "$cellValue";
    $link = mysql_connect($db_host,$db_user,$db_pass);
if(!$link) die ('Could not connect to database: '.mysql_error());
mysql_select_db($db_name,$link);
    for ($row = 2; $row <= $highestRow; ++ $row) 
{
    $val=array();
    for ($col = 0; $col < $highestColumnIndex; ++ $col) 
    {
        $cell = $worksheet->getCellByColumnAndRow($col, $row);
        $val[] = $cell->getValue();
    }
        $sql = "insert into test (F1, F2, F3, F4) values('".$val['0']."', '".$val['1']."', '".$val['2']."','".$val['3']."')";
        mysql_query($sql);
} 
}
mysql_close($link);
?>

Displaying the number of files in a directory and its subdirectorys

Hello, Its my first day coding so please forgive me for some of the silly errors I might make.   I am writing a small upload script and I want to have some sort of orginazation by uploading images to a direcotry based on the day.

The following is my code but it will fail to save the file   Warning: file_put_contents(images/14-09-26/5425905a18bba.png): failed to open stream: No such file or directory   This is becuase the directory with the data part is not created how should I go about first checking that this directory is there and then creating it ?
 

<?php
ini_set('display_errors',1); 
error_reporting(E_ALL);

$today = date('y-m-j'); 
define('UPLOAD_DIR', 'images/' .$today. '/');
$img = $_POST['data'];
$img = str_replace('data:image/png;base64,', '', $img);
$img = str_replace(' ', '+', $img);
$data = base64_decode($img);
$file = UPLOAD_DIR . uniqid() . '.png';
$success = file_put_contents($file, $data);
print $success ? $file : 'Unable to save the file.';
?>

How do you include files from a higher up directory?

I'm currently working on a file in public_html/Directory/otherdirectory and want to  include a config file that's in public_html/Directory so how would I include public_html/Directory/config.php in the public_html_Directory/otherdirectory/index.php file? I've tried using ../ and ../Directory/ in the includes line but got errors both times

Hi All

I am trying to set up a system that where a user sets up an account the system automatically sets up a new directory and inserts template files into it.

I understand mkdir is something to do with it.

Does anyone know how to go about this please?

thanks

Hello. I have a directory with files that look like this:

priceguide_20100809.pdf
priceguide_20100808.pdf
priceguide_20100807.pdf
priceguide_20100806.pdf

I am trying to come up with a function that will grab and save the filename with the biggest date .. ie: priceguide_20100809.pdf.

Any assistance would be greatly appreciated!!
