[SOLVED] How to Add extra HTML text beside each Attribute's value ?

gigamax · December 27, 2013

hello every one . i'm new in prestashop and i dont know how to do this. i'll be so thankful for your advises.

here is the plot :

i have some simple attributes that show me different size of my product.

i just want to add extra HTML text beside each value . this extra field will fill with description with deffrenet css style. for example i have 3 volume of my product :

o 25ml bottle

o 50ml bottle

o 100ml bottle

and i want to show the customers this type of attributes:

o 25ml bottle

include 5% discount !

o 50ml bottle

include 10% discount !

o 100ml bottle

include 15% discount and a free 10ml bottle ! (read more)

i added an extra description field on "ps_attribute_lang" table but i dont know how to use this in prestashop. i want to enter this text beside value and url section of "Attributes and Values". if there is a way to create new datatype it will be amazing.

can you help me friends ?

thank you

Hi.

You need to override the Attribute class and add the new column to the $definition array. Then you need to override 'AdminAttributesGroupsController.php' and create the array 'fields_form_override' in 'renderFormAttributes' and add the new column to it.

thanks dear cartExpert for reply . i didn't know the structure of each files.

i added "desc" field to $difinition . is that correct?

class AttributeCore extends ObjectModel
{
	public $desc;
	
	public static $definition = array(
		'table' => 'attribute',
		'primary' => 'id_attribute',
		'multilang' => true,
		'fields' => array(
			'id_attribute_group' => array('type' => self::TYPE_INT, 'validate' => 'isUnsignedId', 'required' => true),
			'color' => 				array('type' => self::TYPE_STRING, 'validate' => 'isColor'),
			'position' => 			array('type' => self::TYPE_INT, 'validate' => 'isInt'),

			'name' => 				array('type' => self::TYPE_STRING, 'lang' => true, 'validate' => 'isGenericName', 'required' => true, 'size' => 64),
			'desc' => 				array('type' => self::TYPE_STRING, 'lang' => true, 'validate' => 'isString', 'size' => 128),
		)
	);

}

but i dont know how to add your advises into 'AdminAttributesGroupsController.php' . can you help me ?

CartExpert.net · December 27, 2013

Hi.

class AttributeCore extends ObjectModel

should be

class Attribute extends AttributeCore

The file needs to be uploaded to 'override/classes'

Don't forget to add the desc as a property to the class (just like id, or name is).

With 'AdminAttributesGroupsController.php' you need to overried the 'renderFormAttributes' and create the 'fields_form_override' array and add the new field to it (see how fields_form is set up).

$this->fields_form_override = array('type' => 'textarea', 'name' => 'desc', 'label' => $this->l('Description:'), 'lang' => true);

Then need to call the parent's function: parent::renderFormAttributes();

i confused ...

i cant understand the process of over riding the 'AdminAttributesGroupsController.php'. i never done this before.

it is possible to show me the codes ?

Edited December 30, 2013 by gigamax (see edit history)

gigamax · December 30, 2013

well i cancel the over riding process temporary and start to edit core codes just to see the result.

in classes/attributes.php i add extra_desc field to $definition (red codes):

public $extra_desc;

	/**
	 * @see ObjectModel::$definition
	 */
	public static $definition = array(
		'table' => 'attribute',
		'primary' => 'id_attribute',
		'multilang' => true,
		'fields' => array(
			'id_attribute_group' => array('type' => self::TYPE_INT, 'validate' => 'isUnsignedId', 'required' => true),
			'color' => 				array('type' => self::TYPE_STRING, 'validate' => 'isColor'),
			'position' => 			array('type' => self::TYPE_INT, 'validate' => 'isInt'),

			'name' => 				array('type' => self::TYPE_STRING, 'lang' => true, 'validate' => 'isGenericName', 'required' => true, 'size' => 64),
			/*mycode - start*/
			'extra_desc' => 		array('type' => self::TYPE_STRING, 'lang' => true, 'validate' => 'isGenericName', 'required' => true, 'size' => 256),
			/*mycode - end*/
		)
	);

in controlers/admin/AdminAttributesGroupsController.php , i add below codes (red codes) to renderFormAttributes function :

$this->fields_form = array(
			'legend' => array(
				'title' => $this->l('Values'),
				'image' => '../img/admin/asterisk.gif',
			),
			'input' => array(
				array(
					'type' => 'select',
					'label' => $this->l('Attribute type:'),
					'name' => 'id_attribute_group',
					'required' => true,
					'options' => array(
						'query' => $attributes_groups,
						'id' => 'id_attribute_group',
						'name' => 'name'
					),
					'desc' => $this->l('Choose the type of the attribute')
				),
				array(
					'type' => 'text',
					'label' => $this->l('Value:'),
					'name' => 'name',
					'lang' => true,
					'size' => 33,
					'required' => true,
					'hint' => $this->l('Invalid characters:').' <>;=#{}'
				)
				/* mycode - start*/
				,
				array(
					'type' => 'text',
					'label' => 'extra description',
					'extra_desc' => 'extra_desc',
					'lang' => true,
					'size' => 128,
					'desc' => 'show me!!!',
					'hint' => $this->l('Invalid characters:').' <>;=#{}'
				)
				/* mycode - end*/
			)

and ok. the extra_desc field is show up in adding attribute page but when you try to save the attributes, presta gave me an error:

The field extra_desc is required at least in persian.

and of course when i try to edit an attribute , presta gave me php fattal error :

Fatal error: Cannot access empty property in D:\xampp1-8-1\htdocs\atraneh\classes\controller\AdminController.php on line 2382

so where is the problem ? i think i must edit the sql query to include my field in select or save.

CartExpert.net · December 30, 2013

Hi.

/* mycode - start*/
				,
				array(
					'type' => 'text',
					'label' => 'extra description',
					'extra_desc' => 'extra_desc',
					'lang' => true,
					'size' => 128,
					'desc' => 'show me!!!',
					'hint' => $this->l('Invalid characters:').' <>;=#{}'
				)
				/* mycode - end*/

''extra_desc' => 'extra_desc', is incorrect, should be 'name' => 'extra_desc',

a lot of thanks dear cartExpert !! it's working and it's so good

and there is a last question . how can i show my extra field in template ? i know that i must edit product.tpl and <div class="attribute_list"> but i dont know where to call my extra_desc. there is a "$group_attribute" that filled with a varibale "$group" but i dont know where this "$group" filled and initialized.

CartExpert.net · January 3, 2014

Hi.

$group is initialized in the ProductController.php file within the assignAttributesGroups function, so you will need to override this function.

Also, $groups content is populated with the result returned by the 'getAttributesGroups' method of the Product class, therefore this function has to be overriden too. You will need to include the new field in the SQL query of the mentioned function.

Regards.

Robin.

a lot of thanks dear friend. i found the answer with your amazing helps and i just wanna say thanks

magudelo62 · June 25, 2014

Hi Gigamax, CartExpert.

Thanks a lot for your help,

I need to do the same thing that Gigamax, but i can not do the last step.

I did the first steps, and now i have the info on the data base, and i see text area in the back front. it's working and it's so good

But i can not override the function in ProductController.php in assignAttributesGroups and getAttributesGroups in Product class. Could you please explain to me better this step. I tried, but i can not do this.

I put agl.`extra_desc` in the sql, but it doesn`t work. and i do not know where exactly i need to override the product class.

A lot of thanks dear friends.

First of all thank you for your very usefoul tips. I got stucked for hours in overriding renderFormAttributes in ps156 because of this:

http://forge.prestashop.com/browse/PSCFV-11642 (not a bug though)

hope that using: "return AdminController::renderForm();" instead of: "parent::renderForm();" will save someone else's time

cosmy81 · February 19, 2015

Hello, I'm trying to do the same thing, but when I edit the attribute value the form doesn't retrieve the extra_desc value.

But it's stored in the databased and shown in the frontend.

What have I forgetted?

heryfer · May 3, 2016

Hi People,

This is an alternative for replace textarea for HTML editor,

NOTE: in prestashop 1.6 I have to add the column desc to the ps_attribute_lang table

CREATE TABLE `ps_attribute_lang` (

`id_attribute` int(10) unsigned NOT NULL,

`id_lang` int(10) unsigned NOT NULL,

`name` varchar(128) NOT NULL,

`desc` longtext NOT NULL,

PRIMARY KEY (`id_attribute`,`id_lang`),

KEY `id_lang` (`id_lang`,`name`)

) ENGINE=InnoDB DEFAULT CHARSET=utf8;

Forn declaration:

this:

array(

'type' => 'text',

'label' => 'extra description',

'name' => 'desc',

'lang' => true,

'size' => 128,

'desc' => 'show me!!!',

'hint' => $this->l('Invalid characters:').' <>;=#{}'

)

to:

array(

'type' => 'textarea',

'label' => $this->l('Description:'),

'name' => 'desc',

'lang' => true,

'cols' => 60,

'rows' => 20,

'class' => 'rte',

'autoload_rte' => true,

'hint' => $this->l('Invalid characters:').' <>;=#{}',

),

In file Atribute.php rewrite, self::TYPE_HTML is very important

this:

'desc' => array('type' => self::TYPE_STRING, 'lang' => true, 'validate' => 'isGenericName', 'required' => true, 'size' => 256),

to:

'desc' => array('type' => self::TYPE_HTML, 'lang' => true, 'validate' => 'isCleanHtml', 'size' => 4000),

Happy Coding!!!!

Skumbabs · May 4, 2016

Hello,

I did this, and it works almost perfectly.

I need one more tips :

I tried to set a description of the attribute value just under the short description of my product.
So I want to show the correct description when a value is selected in my input select.

For the moment I have all the list with this code :

            <div id="attributes">
                    <div class="clearfix"></div>
                    {foreach from=$groups key=id_attribute_group item=group}
                        {if $group.attributes|@count}
                                    {assign var="groupName" value="group_$id_attribute_group"}
                                    <div class="attribute_list">
                                        <ul>
                                            {foreach from=$group.attributes2 key=id_attribute item=group_attribute}
                                                    <li>{$group_attribute|escape:'html':'UTF-8'}</li>
                                            {/foreach}
                                        </ul>
                                    </div>
                        {/if}    
                    {/foreach}
            </div>

Can you help me to achieve this please ?

Thanks very much for any help or advice !

heryfer · May 4, 2016

Hi Skumbabs

Try this to show the value:

{$group.desc[$id_attribute]}

NOTE: .desc is the name of your custom attribute

<ul>
    {foreach from=$group.attributes key=id_attribute item=group_attribute}
    <li> {$group.desc[$id_attribute]} </li>
    {/foreach}
</ul>

Is very important add this line to the ProductController.php -> line 445 aprox

$groups[$row['id_attribute_group']]['desc'][$row['id_attribute']] = $row['desc'];

$row['desc'] is the row in the database in the table ps_attribute_lang

Best Coding ;-)

When using your code I got exactly the same result.

Maybe I didnt explain myself really good because it set <ul> and <li> in my code.

I need only one information by attribute the desc i added in value.

In example I have a select which is "Color" (Attribute), in the select I have 2 values : Red and Blue.

For the value red I added a desc which is : "Red like beautiful flames,..."

I would like behind the short_description when I choose "Red" -> "Red like beautiful flames,..." shows.

To compare my needs to something existing, it's the same as the price changing when the combination change.

I hope, I'm clearer now :/

And thanks for your help !

Hello,

I'm also adding a description field for attribute values, but I block. I post below my two Override files if anyone can help me.

/override/classes/Attribute.php :
