The gallery shows not the 0 (Zero).

[Sun Zaza]

Hi,

I have a small problem.

I added an additional field to my gallery with this code:

Code: [Select]

alter table 4images_images add column image_hot_hits int (10) DEFAULT '0' NOT NULL
On the details page shows the value {image_hot_hits} only when it has a value of 1 or more.

That means the gallery shows never the 0 (Zero).

I have to show that on the gallery.

What did I do wrong?

[V@no]

what did you add in includes/db_field_definitions.php ?

Code: [Select]

$additional_image_fields['image_hot_hits'] = array($lang['image_hot_hits'], "text", 0);

[V@no]

Never mind that question...4images uses empty() which returns false for emptry string and for "0"

The work around is use something like this:

{ifno field_name}0{andifno field_name}{if field_name}{field_name}{endif field_name}

I just tried it. It is working fine. Thanks v@no.

I hope you can find a faster solution for this issue.

Hi V@no,

Is it normal that the value 0 of the additional field {image_hot_hits} is showing on the ACP (Edit image) and not on the gallery?

PS: Before using {ifno field_name}0{andifno field_name}{if field_name}{field_name}{endif field_name}

[V@no]

Yes, it's expected. It only affects templates. (ACP doesn't use templates)

http://php.net/manual/en/function.empty.php

Returns FALSE if var  has a non-empty and non-zero value.

The following things are considered to be empty:

    * "" (an empty string)
    * 0 (0 as an integer)
    * "0" (0 as a string)
    * NULL
    * FALSE
    * array() (an empty array)
    * var $var; (a variable declared, but without a value in a class)

Ok I understand, but what is the different between image_hits and image_hot_hits? I just want to understant.

The image_hits shows 0 if nobody has see the image yet.

[V@no]

image_hits processes by a separate part of code then additional fields.
