checking title of next image

MuschPusch

Hi,

i want to check in a loop of album.php of the default template what the title of the next image is. This is because sometimes i have front and back pictures of one item (i mention front/back in the title).

This is the loop and i tried a couple of things but i always failed to find a proper solution.

[code]

while (next_image(false, $firstPageImages)):
$desc= getImageDesc();
// hide big pictures when not logged in...
if (zp_loggedin()){
$output.= "<div class='imagethumb'><img src='".getImageThumb(getImageTitle())."'></div>\n";
}else{
$output.= "<div class='imagethumb'><img src='".getImageThumb(getImageTitle())."'></div>\n";
}
$output.= "</div>";
$last_image=getImageThumb(getImageTitle());
endwhile;

[/code]

A simpler way of doing this is to add the information you want to print in the custom_data field of the image. Then you can just display it.

`$custom = $_zp_current_image->getCustomData();` will return what you put in that field in ADMIN.

Hi sbillard,

thanks i will use the custom data field but i want to display the front and back images next to each other. Thats why i need to know if the next image is the back of an item so that i can output different html.

it must be something like this but i don't know how to access information of the next image.

[code]
`

//next image

if ($_zp_NEXT_image->getCustomData()=='back'){

// don't close the div

echo "

n";

}elseif ($_zp_current_image->getCustomData()==back){

//close the div containing two images

echo "

";

}else{

//standard one image div having no back image

echo "

n";

}

`
[/code]

If you know an easier solution i would be gratefull to hear it...

If you name your images, the file names, properly, you could use `getNextImageURL()` to extract the filename and check on that.

To get the next image is easy, it's built in to the image class:

`$nextimage = $_zp_current_image->getNextImage()

if ($nextimage->getCustomData()=='back') {

...`

If someone has similar problem. This was the solution:

`

while (next_image(false, $firstPageImages)):

$desc= getImageDesc();

$output.= "

";

$output.= "

description:
".$desc."

n";

// hide big pictures when not logged in...

if (zp_loggedin()){

$output.= "

n";

}else{

$output.= "

n";

}

if (strpos(getNextImageURL(),"back")!=''){

next_image(false, $firstPageImages);

if (zp_loggedin()){

$output.="";

}else{

$output.="";

}

}

$output.= "

";

$last_image=getImageThumb(getImageTitle());

endwhile;
