[SOLVED] Strip/Change FileName...

[mikem562]

I have the following code which goes through a dir and writes an XML file based on the images inside that folder. I'm encountering two problems.

 

The first is I want it to only select images that end with $file_ext which happens to be _img . I don't want it to select any other photos.

 

Secondly I have this:

$file_img = "$file"; < This will be the name of a file for example jan01_img.jpg

$file_tmb = "INSERT CODE HERE"; < I want this to keep the file name and replace _img with _tmb. Any help would be muchly appreciated. Code can be found below

 

    <?php
       $dir = '../galleries/music/';
       $file_type = "jpg";
       $file_ext = "_img";
       $play_list = "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?>\n";
       $play_list .= "<content>\n";
 $play_list .= "<gallery>\n";
       // Open directory, read contents and add to file_list if correct file_type
       if (is_dir($dir)) {
          if ($dh = opendir($dir)) {
             while (($file = readdir($dh)) !== false) {
                if ($file != '.' && $file != '..') {
                   $name_array = explode('.', $file);
                   
                   if ($name_array[1] == $file_type) {
                      $file_img = "$file";
		    $file_tmb = "INSERT CODE HERE";
                      $play_list .= "<image Thumb=\"$file_tmb\" Large=\"$file_img\"></image>\n";
                   }
                }
             }
             closedir($dh);
             $play_list .= "</gallery>\n";
             $play_list .= "</content>\n";
     $wdir = ''.$dir.'images1.xml';
     $f=fopen("$wdir","w") or die("Could not open and empty the file");
           fwrite($f,$play_list) or die("Could not write to the file");
           fclose($f) or die ("Could not close the resource");        
          }
       }
    ?>

I've got the replace function working now and I have it only selecting the files I need now. My new question is . Is there a way to set a base dir so $dir = '../galleries'; and have some type of forloop that goes through every subdir until it finds a *_img.jpg and when it does, it process's that dir generates the xml there and moves on to the next?

 

<?php
       $dir = '../galleries/music/';
       $file_ext = "img.jpg";
       $play_list = "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?>\n";
       $play_list .= "<content>\n";
 $play_list .= "<gallery>\n";
       // Open directory, read contents and add to file_list if correct file_type
       if (is_dir($dir)) {
          if ($dh = opendir($dir)) {
             while (($file = readdir($dh)) !== false) {
                if ($file != '.' && $file != '..') {
                   $name_array = explode('_', $file);
                   if ($name_array[1] == $file_ext) {
                      $file_img = "$file";
		    $file_tmb = str_replace("_img", "_tmb", "$file");
                      $play_list .= "<image Thumb=\"$file_tmb\" Large=\"$file_img\"></image>\n";
                   }
                }
             }
             closedir($dh);
             $play_list .= "</gallery>\n";
             $play_list .= "</content>\n";
     $wdir = ''.$dir.'images1.xml';
     $f=fopen("$wdir","w") or die("Could not open and empty the file");
           fwrite($f,$play_list) or die("Could not write to the file");
           fclose($f) or die ("Could not close the resource");
                 
          }
       }
       
    ?>

There might be some more elegant ways ofdoing this but this does it also..

<?php
$file = 'test_img.jpg';
$tmb_file = str_replace('_img', '_tmb', $file);
var_dump($tmb_file); // "test_tmb.jpg"

Thanks TeNDoLLA 

Have you any ideas for my last question? I edited the above post ...

I have zero experience on handling dirs so I am not sure if I can help with that much. But if you want to take a look here is a thread discussing about looping through directories which is pretty complicated if you have no experience before of using the iterators: http://www.sitepoint.com/forums/showthread.php?t=626691&highlight=directoryiterator .

 

But if you have or get somehow the dirs in array then you could do something like this

 

<?php
$basedir = '../gallery/'
$subDirs = array('music', 'images', 'images2');
foreach ($dirs as $dir)
{
$currentDir = $basedir . $dir;
// here loop through the files
// in currentDir and create xml
}

 

Also when looping the files through you can use is_dir() function to check if a file is a dir and then you could go into that dir and loop its files again. About creating the xml I already posted to your another thread earlier: http://www.phpfreaks.com/forums/index.php/topic,264713.0.html .

awesome!! Thank you, I'll be sure to post the final result incase anyone else should care to use it =), now just working on sorting the xml / image nodes by date so the newest is always at the top haha and then it will be set!
