help? where to put substr function in gallery script...

[annieone]

hi, i am using  a dynamic folderlist-script in a gallery and it works fine so far.

 

but i do not get it (i am no coder i admit it) how to avoid the first two letters of a dir by using substr method.

 

here is my gallery script which works well except that i would like to prevent folders showing their numbers like 01 at the beginning..:

 

if (isset( $_GET['galerie'] ) )
		{
			echo '<div id="container"><div class="main-content">
				<div style="width:auto;white-space:nowrap;height:530px;background:#585850;position:relative;"><div id="preview">';
			$bilder = glob( "sets/{$_GET['galerie']}/images/*.jpg" );
			natsort( $bilder );
			foreach ($bilder as $bild)
			{
				$bild = array_pop( explode( "/", $bild ) ); // where to put substr function?

				echo '<img src="sets/' .$_GET['galerie']. '/images/' .$bild. '" style="margin-right:2px;"/>';

			}
			echo '</div></div></div>';
		}

 

thanx a lot for any help in grammar for beginners.. :-\

maybe now somebodey can help:

 

i wonder how to avoid the first two letters of a dir by using substr method.

 

here is my gallery script which works well except that i would like to prevent folders showing their numbers like 01 at the beginning..:

 

	<?php
	// Galerien ermitteln
	$verzeichnisse = glob( "sets/*", GLOB_ONLYDIR );
	echo '<div id="nav"><ul>';
	foreach ($verzeichnisse as $dir)
	{
		$dirname = array_pop( explode( "/", $dir ) ); // where do i put substr function?

		echo '<li><a href="' .$_SERVER['PHP_SELF']. '?galerie=' .$dirname. '">' .$dirname. '</a></li>';
	}
	echo '</ul><ul><li><a href="main.php">Main</a></li></ul></div><br class="clear" />';
	?>

 

thanx a lot for any help in grammar for beginners..  ???

substr($dir,1)

 

should fetch the whole string except the first 2 characters, note: indexs start at 0

I do not see where you attempted to do that code.

 

$dirname = substr($dirname, 2);

 

Should remove the first 2 items from the name.

 

EDIT:

Beaten to it, but a correction was needed. Should be 2 not 1.

Could you explain a bit more what you want to do?

An example would be nice.

Strange... didn't get warning that there are replies to this topic before I posted...

oh yeah =\..

 

0 would be from the start

 

1 would be after the first, sorry bro premiso is right

thanks a lot everyone here, meanwhile i came up with even another idea from a pityful friend and now it looks like this:

	<?php
	// Galerien ermitteln
	$verzeichnisse = glob( "sets/*", GLOB_ONLYDIR );
	echo '<div id="nav"><ul>';
	foreach ($verzeichnisse as $dir)
	{
		$dirname = array_pop( explode( "/", $dir ) ); 

		// $dir=substr($dir, 2); << wrong idea.. !

		// better idea..:
		echo "<li><a href=".$_SERVER['PHP_SELF']."?galerie=".$dirname.">".substr($dirname,2)."</a></li>"; 
	}
	echo '</ul><ul><li><a href="main.php">Main</a></li></ul></div><br class="clear" />';
	?>

 

again thank you so much, you've been very kind!
