Smarty Caching | {content block} variable returns null/blank

[leroy]

Hi,

I'm quite new with smarty and I have a question about problems after I activated "Smarty caching".

I have a template where some variables are defined. The input of these values are provided in when someone fills in certain fields when creating a page (and this template selected).

This is the template:

Code: Select all

{process_pagedata}

{content block="menusubtitle" label="Menu subtitel" oneline=true assign="noassign"}
{content block="sitemapCheck" oneline=true default=0 assign="sitemapCheck" label="Exclude page from sitemap? ('1' excludes page)"}
{content block="sitemapFooterCheck" oneline=true default=0 assign="sitemapFooterCheck" label="Exclude page from footer sitemap? ('1' excludes page)"}
{content block="custom_meta_description"  assign="custom_meta_description" wysiwyg="false" label="Meta description" oneline="true" maxlength="160"}
{content block="custom_meta_keywords" assign="custom_meta_keywords" wysiwyg="false" label="Meta keywords (max 5-10 komma gescheiden woorden!)" oneline="true" maxlength="500"}


{content block="custom_alternate_hreflang_nl" assign="custom_alternate_hreflang_nl" wysiwyg="false" label="Alternate hreflang alias voor Nederlandse pagina" oneline="true"}
{content block="custom_alternate_hreflang_en" assign="custom_alternate_hreflang_en" wysiwyg="false" label="Alternate hreflang alias voor Engelse pagina" oneline="true"}
{content block="custom_alternate_hreflang_de" assign="custom_alternate_hreflang_de" wysiwyg="false" label="Alternate hreflang alias voor Duitse pagina" oneline="true"}
{content block="custom_alternate_hreflang_cn" assign="custom_alternate_hreflang_cn" wysiwyg="false" label="Alternate hreflang alias voor Chinese pagina" oneline="true"}

{content block="countrycode" assign="countrycode" label="Taal van de pagina" oneline=true tab="options"}  

{content_module block="page_header_img" module="GBFilePicker" mode="browser" dir="images/" assign="page_header_img" label="Page header image"}

{if empty($page_header_img)}
  {assign var="page_header_img" value="images/v2/header_img.png"}
{/if}

{content block="page_header_title" label="Page header title" oneline="true" assign="page_header_title"}
{if empty($page_header_title)}
  {if ($page_lang == "nl_NL")}
    {assign var="page_header_title" value="Hét online verzendplatform.<br />Vergelijk tarieven, verzend eenvoudig en bespaar direct"}
  {elseif ($page_lang == "en_US")}
    {assign var="page_header_title" value="Parcel delivery without a hassle; reliable, fast and excellent service!"}
  {elseif ($page_lang == "zh_CN")}
    {assign var="page_header_title" value="包裹会以可靠，快速和最优服务送达"}
  {elseif ($page_lang == "de_DE")}
    {assign var="page_header_title" value="Paketzustellung ohne Probleme; zuverlässig, schnell und mit exzellentem Service!"}
  {/if}
{/if}

{content_module block="icon_image" module="GBFilePicker" mode="browser" dir="images/icon_images/" assign="icon_image" label="Icon image (optioneel)"}


{global_content name='test_open_speed'}

        </div>
      </section>
    </article>
  </div>
    {global_content name='_v2_tpl_footer_v2Vervolg'}
</article>
{global_content name='test_close_speed'}

After I enabled "Smarty Caching" and load a page it works all fine (and really fast). However if I load this page incognito all the variables from my template which are used in my "header" global content block pass "null/blank" (e.g. <meta name=description content="")


My header global content block looks like this. Here is the "custom_meta_description" variable for instance being used:

Code: Select all

{cloudflareip}
{babel action="assign"}
{redirect_to_lang_by_ip}

<!DOCTYPE html>
<__html>
<head>


  <meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0" />
 

  {updatecss}{assign_shortlang}{process_currentpagealias}

  <title>{if $blogtitle neq ""}{$blogtitle} | {/if}{title} | {sitename}</title>
 
  <meta name="robots" content="all">


 
  <meta property='og:title' content='{title} | {sitename}' />
  {langify_gcb name="header_ogdescription"}
  <meta property='og:url' content='https://{$smarty.server.HTTP_HOST}{$smarty.server.REQUEST_URI}' />
  
  {metadata}

  <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1" />
  <meta name="author" content="" />
  <meta name="copyright" content="Copyright (C) 2018" />



<meta name="keywords" content="{if $custom_meta_keywords neq ""}{$custom_meta_keywords}{else}{langify_gcb name="default_keywords"}{/if}" />


  <meta name="description" content="{if $blog_meta_description neq ""}{$blog_meta_description}{else}{if $custom_meta_description neq ""}{$custom_meta_description}{/if}{/if}" />
  <meta http-equiv="language" content="{$langcode_short}">

  <link rel="shortcut icon" href="{root_url}/favicon.ico">
   


  {if $custom_alternate_hreflang_nl}<link rel="alternate" hreflang="nl_nl" href="{root_url}/nl_NL/{$custom_alternate_hreflang_nl}" />{/if}
  {if $custom_alternate_hreflang_en}<link rel="alternate" hreflang="en_us" href="{root_url}/en_US/{$custom_alternate_hreflang_en}" />{/if}
  {if $custom_alternate_hreflang_de}<link rel="alternate" hreflang="de_de" href="{root_url}/de_DE/{$custom_alternate_hreflang_de}" />{/if}
  {if $custom_alternate_hreflang_cn}<link rel="alternate" hreflang="zh_cn" href="{root_url}/zh_CN/{$custom_alternate_hreflang_cn}" />{/if}

I'm wondering if someone can tell me why these variables (from the template) are not being passed after enabling the "Smarty Caching".

Code: Select all

CMS Version		1.11.7

Any answer is much appreciated, thanks in advance.

Best regards,

I'm not sure it's related to Smarty caching (I never used it) or a variable scope problem.

You could check if it's a scope problem by adding an extra assignment in your template like this:

Code: Select all

{content block="custom_meta_description"  assign="custom_meta_description" wysiwyg="false" label="Meta description" oneline="true" maxlength="160"}
{$custom_meta_description=$custom_meta_description scope=global}

It will change the scope of the variable to global.

And since you're new to Smarty read up on Smarty template inheritance too. It might be much easier than using global content blocks: https://cmscanbesimple.org/blog/the-pow ... gn-manager

Finally: consider upgrading to the latest version of CMSMS
