[CMS PHP BLOCK] Remove view massiv assignment

[nadar]

In order to not overload the view files of blocks and reduce ram usage the contents of block configs should be requested instead of massiv assigned to the view. This will also fixed the problem to make sure if variables exists with isset() method and allows to define default values if not existing.

Old:

<? if (isset($vars['title'])): ?>
<h1><?= $vars['title']; ?></h1>
<? else: ?>
<h1>Does not exist</h1>
<? endif, ?>

new:

<h1><?= $this->varValue('title', 'Does not exists'); ?></h1>

BC Breaking

The following variables will be removed in the view files by default:

• $vars['foo'], use $this->varValue('foo') instead.
• $cfgs['foo'], use $this->cfgValue('foo') instead.
• $placeholders['foo'], use $this->placeholderValue('foo') instead.
• $extras['foo'], use $this->extraValue('foo') instead.

In order to dirty fix your php block view, insert the following code at the top of your php view file:

// <!-- RC2 UPDATE FIX!
$vars = $this->context->getVarValues();
$cfgs = $this->context->getCfgValues();
$extras = $this->context->getExtraVarValues();
$placeholders = $this->context->getPlaceholderValues();
