    [solved] Sort a gallery by descending date

    in General Support

    Posted

    hi @ShaunaB1 and @Gideon So,

    Thanks for your efforts to help to my problem. Unfortunately a simple "-" does not solve my challenge.  I also tried a "sort(1/iname_3)", where iname_3 contains a timestamp - no success.

    @Gideon SoI did a dump on $images in line 32 and it throws a long list of all parts of the image-field. Sorting itself works as desired, but not with an option "image_created descending".

    Greetings Günter

    [solved] Sort a gallery by descending date

    in General Support

    Posted · Edited by biber

    Hi,

    I have built a site with some galleries, which can be ordered by different criteria, like place, name or date_created. This works fine, iname_1,2 or 3 can be chosen by user.

    Now I want to have the option to sort the images "latest image first".  Setting "rsort" instead of "sort" in line 31 comes up with this error:

    Where is my mistake? Any idea?

    Problem with accessing userdefined image-fields

    in General Support

    Posted

    Hi all,

    still have problems with that userdefined fields:

    to every image I have defined some fields, represented by a number in the database-field "filedata". Here one example: 

    {"_109":{"data":"ehemalige Post","data1015":""},"_108":"schon lange gibt es hier kein Postamt mehr","_110":"S\u00f6rup Dorf","_111":"","_112":"2024-02-17 00:00:00","_114":""}

    _109="kopf", _108="bildtext", _110="iname_1", _ 111="iname_2" and _112="iname_3"

    I can access to this content by $images->$seg1->filedata['_xxx'] for all parts but not to _109(kopf), which is a TextLanguage-field and contains two parts. While I do not need the language-function anymore, I tried to convert it to a simple Text-field, but this lead to a long error-list and no success.

    Any idea?

    hi @ngrmm,

    thanks for your reply.

    maybe I have shortened my code-excerpt too much ? 

    $seg1 = $sanitizer->pageName($input->urlSegment1);

$images = $page->images;

    name_1 defines a sort criteria, not importent in this context.

    My problem is:

    At the overview with all thumbnails I can access to my user-defined imagefields (for exemple field "kopf"). But if I select one image I only get an empty string.

    $images->$seg1->get('kopf|name_1') shows field 'kopf' as expected.

    $images->$seg1->get('kopf')  shows an empty string

    Hi,

    in a gallery I have defined some extra fields to my image-field.

    As long as I show the overview with all thumbnails I can access to my fields (for exemple field "kopf"). But if I select one image I only get an empty string. Very strange: if I get ('kopf|name_1') it shows the content of the "kopf"-field. ("name_1" is a field at the page without reference to the image)

    Here an excerpt from my template:

    Migrate a gallery from ImageExtraFields to current version

    Thanks @ngrmm,

    I have read the announcement about the new custom field option.

    My problem is: I have a site with about 1500 images with more or less text in ImageExtraFields. This is stored all together in one field 'filedata' as shown in my first post. Now I want to separate this content and put it into fields 'caption', 'description', 'textarea', which are existing in the database, but empty.

    Here a screenshot of the database structure:

    Hi,

    I have built a simple website  based on image-galleries some years ago. (malabu.de) To add descriptions I used the ImageExtraModule by just3be. In the database I can see, that some of the data are collected in the field 'filedata' in the table field_images, while the fields  'caption', 'description', 'textarea' stay empty. It looks like 

    {"_109":{"data":"ehemalige Post","data1015":""},"_108":"schon lange gibt es hier kein Postamt mehr","_110":"S\u00f6rup","_111":"einhundertelf","_112":"2024-02-17 00:00:00"}

    very confusing.

    I would prefer to get the content seperated into the standard fields like 'caption', 'description', 'textarea'

    Uncaugt TypeError while changing PHP from 7.4 to 8.2.7

    Hi,

    I copied my website malabu.de on a local LAMP-server which runs PHP 8.2.7 and got the following Fatal Error:
