Numbering images

Rain

By looking at another theme, I've managed to add the "Images 1-10 of 57" option to the album pages of the theme I'm working on by using the method below:

`
<?php
$firstImage = null;
$lastImage = null;
if ($myimagepage > 1) {
?>

<?php
}
while (next_image(false, $firstPageImages)) {
if (is_null($firstImage)) {
$lastImage = imageNumber();
$firstImage = $lastImage;
} else {
$lastImage++;
}
if (isLandscape()) {
$iw = 89;
$ih = NULL;
$cw = 89;
$ch = 67;
} else {
$iw = NULL;
$ih = 89;
$ch = 89;
$cw = 67;
}
echo '';
}
if (!is_null($lastImage) && $lastImage < getNumImages()) {
$np = getCurrentPage()+1;
?>

<?php
}
?>

<?php
if (!is_null($firstImage)) {
echo '<div class="count">';
printf(gettext('Images %1$u-%2$u of %3$u'), $firstImage, $lastImage, getNumImages());
echo "";
}
?>
`
I have two questions.
1. Is this the most efficient method of doing this?
2. Is there a way to display a similar function on the images page, ie "Image 4 of 57"? I suspect I have to change the `printf(gettext('Images %1$u-%2$u of %3$u'), $firstImage, $lastImage, getNumImages());` part to something else, but what?

Thanks a lot.

`echo "Image ". imageNumber()." of ".getNumImages()` for example. All documentated on our functions guide by the way.
Since yout set the number of images per page you can use `getOption('images_per_page')` to calculate the x to y of z number thing.

the `printf()/gettext()` in your example is just for translation support via gettext. If you don't need that at all you can skip that. Without this would read `echo "Images ".$firstimage." - ".$lastimage. " of ".getNumImages()`

Thanks, the "Image # of #" works beautifully. Though with this `echo "Images ".$firstimage." - ".$lastimage. " of ".getNumImages();` I get this output `Images - of 76`?

Edit // Never mind, just had to change "firstimage" to "firstImage", and "lastimage" to "lastImage". Thanks for the help!

`getNumAlbums();` prints the number of total albums in the index, but is there a way to print the total number of images in all the albums as well? Couldn't find that in the functions guide. Same with returning something like "Albums 1-20 of 28" if I've set ZP to show 20 albums per page -- are these things possible?

acrylian

Sure, `echo $_zp_gallery->getNumImages()`.

Rain

Oh excellent! What about the "Albums 1-20 of 28" if I've set Zenphoto to show 20 albums per page for example?

acrylian

`$_zp_page` stores the index/album page you are currently on and `getOptions('albums_per_page')` gets, well obvious, isn't it...:-). For the total number of albums you already now it. Just do some calculating based on the page number to achieve that.

part of the code you have quoted is not related to the `n-m of p` so you can delete
`
if (isLandscape()) {
$iw = 89;
$ih = NULL;
$cw = 89;
$ch = 67;
} else {
$iw = NULL;
$ih = 89;
$ch = 89;
$cw = 67;
`
being careful, of course to not screw up the if/else sets.

look at the Effervescence+ theme customfunctions. It has a `printNofM()` function.

Thanks! Clean code = good code.
