Concrete5 - how to get page_list edit screen to read values in custom fields

Question

1. Setup

We've added two layout dropdown fields to the page_list block's edit screen by overriding:

• db.xml
• page_list_form.php
• Adding the fields to the view

---

2. In db.xml we've added:

<field name="gridSize" type="C" size="255">
</field>
<field name="gridPaddingStyle" type="C" size="255">
</field>

---

3. In page_list_form.php

We've added the slect fields to the block edit screen like this:

  <div class="ccm-block-field-group">
    <h2><? echo t('Grid layout')?></h2>

    <p><? echo t('Grid size')?></p>
      <?php
          $gridSize = array(
          '1up' => 'grid-list-item-single grid-unit-1',
          '2up' => 'grid-unit-2',
          '3up' => 'grid-unit-3',
          '4up' => 'grid-unit-4',
          '5up' => 'grid-unit-5',
          '6up' => 'grid-unit-6'
          );

          if (is_array($gridSize)) :
      ?>
      <select name="gridSize" id="selectGridSize">
          <? foreach ($gridSize as $gridItem => $value) : ?>
          <option value="<?= $value ?>" <?php if ($gridSize == $value) { ?> selected <?php } ?>>
          <?= $gridItem ?>
          </option>
          <? endforeach; ?>
      </select>
      <? endif; ?>

      <p><? echo t('Grid padding style')?></p>
      <?php
          $gridPaddingStyle = array(
          'Padding' => '',
          'No padding' => 'grid-no-padding',
          'Hairline' => 'grid-hairline'
          );

          if (is_array($gridPaddingStyle)) :
      ?>
      <select name="gridPaddingStyle" id="selectPaddingSize">
          <? foreach ($gridPaddingStyle as $gridPaddingStyleItem => $value) : ?>
          <option value="<?= $value ?>" <?php if ($gridPaddingStyle == $value) { ?> selected <?php } ?>>
          <?= $gridPaddingStyleItem ?>
          </option>
          <? endforeach; ?>
      </select>
      <? endif; ?>
  </div>

---

4. In the view.php we've added:

$gridSize = $controller->gridSize;
$gridPadding = $controller->gridPaddingStyle;

Which obviously pulls the data out of the database for use when we output the markup.

---

Everything works great except when we come to re-edit the block - essentially the values previously set for our custom fields don't get read and the dropdowns revert back to the first items in the select lists.

---

5. Question

How do we get the page_list edit screen to read the values previously set in the database?

---

Any pointers in the right direction would be much appreciated (sorry, can't work out how to get syntax highlighting working - wish the markdown was the same ad Github issues).

Cheers

Answer 1

Your problem here is that you're overwriting the variables in your edit view $gridSize = array(...) just before you're trying to access them, you can probably fix it by changing those array variable names to something semantic like "grid_size_options".

If that doesn't work, you can use $this->set to pass variables to the view from the controller edit method. Your edit method would look something like this:

public function edit()
{
    $this->set('grid_size', $this->gridSize);
    $this->set('grid_padding_style', $this->gridPaddingStyle);
}

and then your edit view can just magically access $grid_size and $grid_padding_style.

 <select name="gridPaddingStyle" id="selectPaddingSize">
     <?php 
     foreach ($gridPaddingStyle as $gridPaddingStyleItem => $value) {
         ?>
         <option value="<?= $value ?>" <?= $grid_padding_style == $value ? 'selected' : '' ?> >
             <?= $gridPaddingStyleItem ?>
         </option>
         <?php
    }
    ?>
</select>
