Currently working on a custom module and I’m trying to render a set of arrays that are created through a blockForm and a blockSubmit this ones are working correctly. blockForm is creating the fields of the form correctly and blockSubmit is saving the data of the fields correctly. I tested this several times with positive results. And this two are working with a FOR loop.

Now i’m trying to render the data of this blockForm with public function build() and a FOR loop. But is only rendering the first array and as it is configurated at the moment is should be four arrays.

This is the code:

FssContentBlock.php

<?php  namespace Drupal\fss_content\Plugin\Block;  use Drupal\Core\Block\BlockBase; use Drupal\Core\Block\BlockPluginInterface; use Drupal\Core\Form\FormStateInterface;  /**  * Provides a 'Fussion Content Block' Block.  *  * @Block(  *   id = "fss_content",  *   admin_label = @Translation("Fussion Content Block"),  *   category = @Translation("Fussion Content Block"),  * )  */  class FssContentBlock extends BlockBase implements BlockPluginInterface {    /**    * {@inheritdoc}    */   public function build() {//ONLY RENDER FIRST ARRAY...     $  config = $  this->getConfiguration();   $  config2 = \Drupal::config('fss_content.settings');   $  config2->get('fss_content.paragraphs');   $  qtty = $  config2->get('fss_content.paragraphs');     for ($  i = 0; $  i < $  qtty; $  i ++) {      $  i = $  config['fss_content_paragraph'][$  i];      $  block1 = array        (         $  i => array          (           '#prefix' => '<p>',           '#suffix' => '</p>',           '#markup' => t('@i', array('@i' => $  i,)),          ),        );    }      $  block2 = array       (         'test' => array         (           '#markup' => $  qtty . '<p>' . $  i . '</p>', //TESTING $  qqty VALUE. IT IS CORRECT... BUT WEIRD $  i VALUE...         )       );     $  allblocks = array_merge($  block1, $  block2);   return $  allblocks;  /* //THIS CODE WORK... BUT NEED IT TO WORK WITH (FOR - LOOPS)     $  p0 = $  config['fss_content_paragraph']['0'];     $  p1 = $  config['fss_content_paragraph']['1'];     $  p2 = $  config['fss_content_paragraph']['2'];     $  p3 = $  config['fss_content_paragraph']['3'];      $  block = array         (        'p0' => array             (        '#prefix' => '<p>',        '#suffix' => '</p>',              '#markup' => t('@p0', array('@p0' => $  p0,)),             ),       'p1' => array             (        '#prefix' => '<p>',        '#suffix' => '</p>',              '#markup' => t('@p1', array('@p1' => $  p1,)),             ),       'p2' => array             (        '#prefix' => '<p>',        '#suffix' => '</p>',              '#markup' => t('@p2', array('@p2' => $  p2,)),             ),       'p3' => array             (        '#prefix' => '<p>',        '#suffix' => '</p>',              '#markup' => t('@p3', array('@p3' => $  p3,)),             )      );     return $  block;  */   }//End build    /**   * {@inheritdoc}   */   public function blockForm($  form, FormStateInterface $  form_state) { //THIS WORK...     $  form = parent::blockForm($  form, $  form_state);     $  config = $  this->getConfiguration();      $  config2 = \Drupal::config('fss_content.settings');     $  config2->get('fss_content.paragraphs');     $  qtty = $  config2->get('fss_content.paragraphs');      $  form['fss_content_paragraph'] = array(       '#type' => 'fieldset',       '#tree' => TRUE,     );      for ($  i = 0; $  i < $  qtty; $  i ++) {       $  num = $  i + 1;       $  form['fss_content_paragraph'][$  i] = array(         '#type' => 'textarea',         '#title' => 'Parrafo N°' . $  num,         '#default_value' => isset($  config['fss_content_paragraph'][$  i]) ? $  config['fss_content_paragraph'][$  i] : '',       );     }    return $  form;    }   /**    * {@inheritdoc}    */   public function blockSubmit($  form, FormStateInterface $  form_state) { //THIS WORK...     parent::blockSubmit($  form, $  form_state);     $  values = $  form_state->getValues();      $  config2 = \Drupal::config('fss_content.settings');     $  config2->get('fss_content.paragraphs');     $  qtty = $  config2->get('fss_content.paragraphs');       for ($  i = 0; $  i < $  qtty; $  i ++) {       $  this->configuration['fss_content_paragraph'] = $  form_state->getValue('fss_content_paragraph',$  i);     }   }//End blockSubmit  }//End Class 

Explanation of how the module work:

• The module has a configuration option that sets the amount of fields the Administrator user needs.

• Then the form with the amount of fields is created:

• And this is what my code is rendering at this moment:

As you can see is rendering the first array but nothing else.

Now, if you take a look at the test i’m making the $ qtty value is correct witch is the value of the amount of fields i need.

But the last value of $ i is weird (last_value_$ i = “ABCE”). Because is taking the first three characters of the first array (First_array = “ABCD”) and the first character of my second array (Second_array= “EFGH”)

Any ideas how can i solve this problem? Thank you!
