Hey

I am currently making a gallery and have come a long way.

What I want to do now is:
$title=$name

where $name is file-with-dashes.jpg

Now I want $title to be $name with dashes replaced with spaces and .jpg removed.

I have shortened text before but never chopped off the ending...

PHP Code:


		
			
$title = substr(str_replace('-', ' ', $name), 0, -4);

Should do it.

Owen	04-02-2004 01:39 PM

thanks man! I'll post a link to the gallery here once it's done.

I'm curious, what is the 0 and the -4 in this code for?

NTLDR

The 0 is the start position and the -4 is the end position, ie chop 4 characters off the end.

Oh, ok, you mean like chop off the .jpg or .gif?

Yep :)

Thanks! See? Even an old dog can learn new tricks. ;)

What if I want to display the first word that comes before a dash?

like:
file-with-dashes.jpg = file

PHP Code:


		
			
$parts = explode('-', $name);

$file = $parts[0];

Code:

<?php 

if ($handle = opendir('.')) {

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

       if ($file != "." && $file != "..") { 

           echo "$file\n"; 

       } 

   }

   closedir($handle); 

}

?>

How do I exclude index.php from this? and if possible anything other than folders.

www.php.net/is_dir function checks for directories :)

Owen	04-02-2004 04:50 PM

Yup I figured it out. I used the readdir function.

Owen	04-02-2004 05:00 PM

How do I get rid of those dots? Also how do I sort this alphabetically?

PHP Code:


		
			
<?php

   $path = "."; // even "."

   if ($dir = @opendir($path)) {

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

           if (is_dir($path."/".$file)) {

               echo $file."<br />";

           }

       }  

       closedir($dir);

   }

?>

Displays:
.
..
Ford
Infiniti
Mercedes
BMW
Nissan
Volvo

Owen	04-02-2004 09:02 PM

Well I did an extremely crude fix:

PHP Code:


		
			
<?php

   $path = "."; // even "."

   if ($dir = @opendir($path)) {

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

           if (is_dir($path."/".$file)) {

        $title = str_replace('.', '<img width=0 height=0 border=0>', $file);

               echo "<a href=\"$file/\">$title<a/><br>";

           }

       }  

       closedir($dir);

   }

?>

The 2nd argument of str_replace can be blank. You can substitute the first argument with an empty string, instead of using an image tag (which makes no sense).

Owen	04-02-2004 10:15 PM

No if I put a space in the br's have effect, but if there is 0 pix images there is nothing to <br>
