Did you realy read and understand my question? or you like to copy paste ?

Calm down @davie. I checked your question quickly. I wrote usage of content elements in FAQ Its not a copy / paste. I think @Michel-Ange will give you true answer!

I understand what Davie is asking - if I have a content element called 'Fred' which contains several entries 'Wilma', 'Barney' and 'Betty', he wants to display all of them without having to specifically reference them.

This is a good idea and something I'd like details on how to do, even better if possible to limit to a certain number returned (i.e. 3, 5 or 10).

ukyo · 2011-09-19 19:33:32

You can check "application/libraries/Tagmanager/Element.php" maybe you can find your answer there!

thedoglett · 2011-09-19 20:24:23

Hmmm, problem is I'm no php expert and I'm really struggling to work out how to call it! Its there, in front of me, and I've been trying to get it work for the past two hours but I'm just not seeing it!

Are we talking something like...

<ion:elements type="article"  name="ElementName">
  <ion:fields />
</ion:elements>

or

<ion:elements type="article" >
  <ion:fields from="ElementName" limit="2" />
</ion:elements>

...because its not working for me!

Another clue/nudge please?!

OK - I give up!

I've tried goodness knows how many permutations of from=, limit=, type=, the lot and I'm sure I'm missing something really simple but I can't figure it out for the life of me (as I said, I'm not a php guru, I only have a very basic grasp of it).

Can someone please explain to me how to loop through a content element I have called 'quotes' which has three fields in it so I can display each of them?

This is pretty urgent now so if its at all possible to give me an answer soon it would be appreciated!

Many thanks.

Hi again.

I found some interesting code inside Element.php

public static function tag_element_fields($tag)

This function should return all elements but for me it looks unfinished.
There is no code to handle translations for example. (Look function above)
And no strings are returned.

My modified function looks now diffrent, it is not a beauty but it works

    public static function tag_element_fields($tag) {
        $element = $tag->locals->element;

        $str = '';
        if (!empty($element['fields'])) {
            foreach ($element['fields'] as $field) {

                $tag->locals->field = $field;

                if ($field['translated'] == '1') {
                    if (isset($field[Settings::get_lang('current')]['content'])) {
                        $field['label'] = $field[Settings::get_lang('current')]['label'];
                        $field['content'] = $field[Settings::get_lang('current')]['content'];
                        if ($field['content'])
                            $str .= $field['label'] . ' - ' . $field['content'] . '<br />';
                    }
                } else {
                    if ($field['content'])
                        $str .= $field['label'] . ' - ' . $field['content'] . '<br />';
                }
            }
        }
        return $str;
    }

Will display all elements , and if some are empty omits them.
Hope someone cleans the code a little and make it even better.

OMG i came to another problem labels are NOT translated.
anyone have idea to enable translation of labels.
Database will not allow me to do that i thnik.

Labels not for multilang websites! Normally labels for "Admin Panel".

if you use content elements like this codes:

<ul>
<ion:elements type="article" name="your_element_name">
     <li><strong><ion:translation term="my_element_field_title_1" /> :</strong> <ion:field name="your_element_field_1" /><li>
     <li><strong><ion:translation term="my_element_field_title_2" /> :</strong> <ion:field name="your_element_field_2" /><li>
     <li><strong><ion:translation term="my_element_field_title_3" /> :</strong> <ion:field name="your_element_field_3" /><li>
</ion:elements>
</ul>

you can manage content elements much better. you can apply styles etc. This is my idea!

thedoglett · 2011-09-20 17:30:29

@ukyo - doesn't your method involve specifying exactly which fields from a content element you want to display rather than just displaying all fields within a content element?

Surely there must be a way to list all fields in a specific content element in a way similar to the following?

<ion:elements type="article" >
  <ion:fields from="ElementName" limit="2" />
</ion:elements>

How will you appy style for your element fields? Will you edit "Element.php"? For make custom style?

thedoglett · 2011-09-20 18:34:47

I was thinking of using the tag="" method as it works with the normal ion:field manner - like this:

<ion:elements type="article" >
  <ion:fields from="ElementName" limit="2" tag="blockquote" />
</ion:elements>

This would loop through all fields from ElementName and return them in a (in this example) blockquote tag.

To clarify what I'm doing in this instance, I'm pulling several customer quotes (field 1 = "fantastic service...", field 2 = "friendly staff.." etc) from a content element called "CustomerQuotes" which when returned will each be wrapped in a blockquote tag which will be styled via css. I hope that makes sense.

Element.php need ionize core team edit for your needs! Core team could give true answer for content elements!

thedoglett · 2011-09-20 19:25:25

Calling the core team - we need you!

@Core Team !!! Wake up !
Where is the core team ? Sleeping ???

OK, guys, we will have a deeper look on that !

thedoglett · 2011-09-22 22:46:36

Thanks Michel. At the same time, it may be an idea to include ordering - so either ascending, descending or (drum roll...) random!

<ion:elements type="article" >
  <ion:fields from="ElementName" limit="5" order="random" tag="blockquote" />
</ion:elements>

Random would enable you to pul a certain number of fields into your layout but in a random order - that way you don't have fields appearing in the same order on each page (so your home page will show fields 1, 5 and 10 whilst your contact page may show 7, 18 and 12).

Michel-Ange · 2011-09-23 01:43:57

@Davie : Unfortunately not the good way...

It must be possible to separate the field label from its content.
Tags are done for that, to atomize data as it should.

But no stress, the asked feature is ready to be launched (on GitHub, official in 0.9.8 as it alter one table and adds another table)

Michel-Ange · 2011-09-23 03:33:04

It is now possible to edit / display the label of each field, translated.
Same for the element title.

Installation (from 0.9.7)

1. Backup your database.
2. Make the test first locally or on a dev server.
3. Execute this code on your DB :

            CREATE TABLE IF NOT EXISTS element_definition_lang (
              id_element_definition int(11) unsigned NOT NULL,
              lang varchar(3) NOT NULL,
              title varchar(255) NOT NULL default '',
              PRIMARY KEY  (id_element_definition, lang)
            ) ENGINE=InnoDB  DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci COMMENT='0.9.7';

        insert into extend_field_lang select id_extend_field, lang, label from extend_field, lang;

        ALTER TABLE `extend_field` DROP `label`;

Update to the last Git version : https://www.github.com/ionize/ionize/

If you want to manually update, the modified files are :

/application/controller/admin :
- element.php
- element_definition.php
- element_field.php
- extend_field.php

/application/libraries/Tagmanager :
- Element.php

/application/models/ :
- element_model.php
- extend_field_model.php

/themes/admin/views :
- element_definition.php
- element_detail.php
- element_field.php
- extend_field.php

Usage :

In this example, I've created one Element with the name "concert".
The title of the element is available for each element through the <ion:attribute name="title" /> tag.

In this example, I created one field "date" in the element "concert".
For each field, we can display the label, in each language.

<ion:elements type="concert">

        <ion:attribute name="name" />
        <ion:attribute name="title" />
    
        <ion:fields>
            
            <ion:attribute name="name" />
            <ion:attribute name="label" />
            <ion:attribute name="content" />
            
            <!-- Same as <ion:attribute name="content" /> -->
            <ion:field name="date" />
            
        </ion:fields>

</ion:elements>

@thedoglett : For the moment, the Content Elements don't have a parent context, but only one parent.
In other words, one Content Element cannot be linked to 2 parents at the same time.
What you ask about order will need to add context for Content Elements.

That's possible, we're thinking to something like that, but not for the next weeks.

thedoglett · 2011-09-23 14:49:41

Thanks for getting back to me Michel, I was just thinking if it worked similarly to how you display articles for the blog (i.e. showing several child articles from a page = showing several fields from a content element) it would be quite handy. Will be interesting to see what's in the next release.

Davie · 2011-10-25 15:10:25

Michel-Ange - thanks a lot !!! superb i'm already using this feature and have a big banana on my face.
Keep up the good work.
