[ZNOTE] Cache

[raf]

I've already added shop pulling offers from database instead of config.php array.

Now i'm working on adding, deleting and modifying offers. Adding works, offers also shows but only when i add new one. So whenever i go only on a admin_shop.php page, it doesn't show (cache is not caching).

This is a piece of code to show offers:

<h1>Shop Offers</h1>
<?php
$cacheOut = new Cache('engine/cache/shop_offer');
if ($updateCache === true) {
  $shop_offersOut = fetchAllshop_offers();
  $cacheOut->setContent($shop_offersOut);
  $cacheOut->save();
} else {
  $shop_offersOut = $cacheOut->load();
}
if (isset($shop_offersOut) && !empty($shop_offersOut) && $shop_offersOut !== false) {
  ?>
  <table class="ui celled striped table" id="shop_offerTable">
    <thead>
      <tr>
        <th>Name</th>
                <th>Delete</th>
                <th>Update</th>
      </tr>
    </thead>
    <tbody>
      <?php
      foreach ($shop_offersOut as $shop_offer) {
      ?>
      <tr>
        <td><?php echo $shop_offer['description']; ?></td>
        <td>
          <form class="ui form" action="" method="POST">
            <input name="delete" type="hidden" value="<?php echo $shop_offer['id']; ?>">
            <input name="action" type="hidden" value="1">
            <input class="ui red mini submit button" type="submit" value="DELETE">
          </form>
        </td>
        <td>
          <form class="ui form" action="" method="POST">
            <input name="shop_offerId" type="hidden" value="<?php echo $shop_offer['id']; ?>">
            <input name="action" type="hidden" value="2">
            <input class="ui orange mini submit button" type="submit" value="UPDATE">
          </form>
        </td>
      </tr>
      <?php
      }
      ?>
    </tbody>
  </table>
  <?php
} else {
  ?>
  <h2>Currently no shop offers in database.</h2>
  <?php
} ?>

Which only works if i add item (after refresh it's gone again, but stays in database).

Lets see if the cache can write/update the cache file:

$cacheOut = new Cache('engine/cache/shop_offer');
$cacheOut->setContent( fetchAllshop_offers() );
$cacheOut->save();

Does the file in engine/cache/shop_offer get updated? If not, it is missing write permissions.

Omg, yup, did

chown www-data:www-data shop_offer.cache.php

and it works fine!
