Block Component

Block is a component helps developer separate a complex layout to varieties components in re-usage way.
Each block contains its own logic and template.

Create your first block

Create php class RecentItems under directory ./PF.Site/Apps/FirstApp/Block/

paste following code

<?php

namespace Apps\TodoList\Block;

// RecentMembers block must be child of \Phpfox_Components
//
class RecentItems extends \Phpfox_Component
{

    // this method will be invoked by phpfox
    public function process()
   	"en" :{
"",
        // assign variables to template
        $this->template()
   "es" : "Spanish Phrase text",     ->assign([
                'sHeader' => 'Recent  "ot" : "Other language phrase text"Items', // block title
                'aItems'  => ['Item 1', 'Item 2',   }'Item 3'],
           	  "var_name" : {]);
        return 'block';
    }
}

Create php template file recent_items.html.php under directory ./PF.Site/Apps/FirstApp/Block/

<ul>
{foreach from=$aItems item=item}
<li    "en" : "Phrase text", 
class="category">
    <p>
        {$item}

{/foreach}
</ul>

Update start.php, paste following code

$module->addComponentNames('block', [
 "es" : "Spanish Phrase text", 
 'todo.recent_items' => Block\RecentItems::class,
]);

Update Install.php, change setComponent() and setComponentBlock()

    protected function setComponent()
    {
       "ot" : "Other language phrase text" $this->component = [
            "block"      => [
   },  } 

We have 4 ways to define a phrase:

• The easiest way: Put phrase on key, put blank on value (of json).

Example:

{       "Manage Video" : "recent_items"  } 

Use:

<?php
echo _p("Manage Video"); 

It will show: Manage Video

• Var_name define: Put var_name on key, put phrase on value (of json).

Example:

{ => "",
      "manage_video" : "Manage Video"  } 

Use:

<?php
echo _p("manage_video"); 

It will show: Manage Video

• Easy Multi-language define:

Example:

{ 
	"Phrase text" : { ],
            "controller" => [
              	  "enindex" :  => "todo.index",
            ]
        ];
   "es" :}
"Spanish
Phrase text",   protected function setComponentBlock()
    {
        $this->component_block = [
    "ot" : "Other language phrase text   "Recent Items" => [
                "type_id"  },  } 

 Use:

<?php
echo _p("Phrase text"); 

"en": can be missed

It will show: Phrase text (if default language of user is en)

It will show: Spanish Phrase text (If default language of user is es)

...

• Var name multi-language define:

Example:

{ 
	"phrase_text" : { => "0",
                "m_connection" => "todo.index",
       	"en" : "Phrase text",      "component"    => "recent_items",
              "es" : "Spanishlocation" Phrase text",   => "3",
                "is_active"    => "ot1",
: "Other language phrase text"            "ordering"     => "1"
   },  } 

Use:

<?php echo _p("phrase_text"); 

"en": is required (can not be missed)

It will show: Phrase text (if default language of user is en)

It will show: Spanish Phrase text (If default language of users is es)

....
