Problem with getNextImageURL

PierreSnugg

Hy, i customized the workflow of the image.php.

so if you click on a image it goes directly to the next one, i wrote:

`

<?php } if (hasNextImage()) { ?>

"><?php printDefaultSizedImage(getImageTitle()); ?><?php } ?>

`

So my problem is, that as soon as you come to the last image, it doesn´t show up (makes sense if you got this function on a button..)

how can i hack that?

1. to show the last image and if there is no image after just stop there, or remove the
link function

or better

2. start looping again from the first image of the album...

Is that possible?

That is a little confusing, do you want the link to be shown if there is no next image or not?

Anyway, how about?: `if(next_image()) { show link } else { do something }`

The nightly build has functions for first and last image:

Ok, i wrote:

`

<?php } <br />
if (hasNextImage()) { ?>

"><?php printDefaultSizedImage(getImageTitle());} <br />
else ?>

<?php printDefaultSizedImage(getImageTitle()); ?>

`

how can i now loop back to the first? sorry, couldn´t find it in docmentation...

BTW, you code misses two "{" and "}" for the else part and the `` is not correct, too.

PierreSnugg

for some reason, that works:

`<?php } <br />
if (hasNextImage()) { ?>

"><?php printDefaultSizedImage(getImageTitle());}<br />
else { ?>

"><?php printDefaultSizedImage(getImageTitle());?>}

<?php }?>`

but of course there is a missing after the if statement. don´t know where to place...

PierreSnugg

can somebody correct that code? it works, but i know there is something wrong.
I don´t get the link closed!

`

<?php } <br />
if (hasNextImage()) { ?>

"><?php printCustomSizedImageMaxHeight(400);}<br />
else { ?>

"><?php printCustomSizedImageMaxHeight(400);?>

<?php }?>

`

The first link is not closed.

PierreSnugg

well, where should i close?

i tried to close after the '}' but than i get an error. i think something else is wrong.
maby the declaration of the if/else statement.

somebody knows?

You just need to look at the second link...

PierreSnugg

If i write:

`

<?php } <br />
if (hasNextImage()) { ?>

"><?php printCustomSizedImageMaxHeight(400);?>

else { ?>

"><?php printCustomSizedImageMaxHeight(400);?>

<?php }?>

`

i see beside my image "else { ?>" showing up and the last image is missing...

acrylian

Of course, you need to look closer. the `else`needs to be `<?php else { ?>`. Always close what you open and always open what you close..:-)
