 Posted: Thu Mar 01, 2018 1:39 pm Post subject: include and dynamic attribute value |
 |
|
Hello,
I am using an include in a foreach loop:
| Code: | {foreach $home_sections as $section}
{include file="sections/{$section.template}"}
{/foreach} |
Now, I am trying to set the nocache attribute of {include} dynamically, based on a property of $section.
I have checked the potential values of the nocache attribute (true and false, default to true) and the different ways of setting attribute values
https://www.smarty.net/docs/en/language.syntax.attributes.tpl
I keep getting a "illegal value of option flag nocache", I have tried:
nocache=$section.nocache
nocache="$section.nocache"
nocache={$section.nocache}
nocache="{$section.nocache}"
also all those using a bespoke modifier "bool":
function smarty_modifier_bool($string){return $string === 'true' ? 'true' : 'false';}
You can see the despair in the pattern...
of course I can do
| Code: | {if $section.nocache}
{include nocache}
{else}
{include}
{/if} |
But I do not see any reason my attempts are failing...
Thank you for any help! |

| Your attempts are failing because "nocache" is a flag, not option. It has no parameters. |

Even if {include nocache=true} and {include nocache=false} are working as expected?
From
https://www.smarty.net/docs/en/language.syntax.attributes.tpl:
{include file="header.tpl" nocache} // is equivalent to nocache=true |

If you want an honest answer, I think you're doing something wrong on a fundamental level.
Rethink your approach to templating. |

Looking at the {include} function:
https://www.smarty.net/docs/en/language.function.include.tpl
we see that nocache is not in the table of attributes, rather it is in the table of flags. So, while the name is the same, I will conclude its semantic meaning is different. (I also conclude the page you mention has an erroneous example.)
I would also try wrapping all three lines inside a nocache block: | Code: | {nocache}{foreach $home_sections as $section}
{include file="sections/{$section.template}"}
{/foreach}{/nocache} |

The problem is, he for some reason wants selective caching/nocaching behavior on a consistent dataset.
Or his dataset is NOT consistent and should have never been in the same array. |

| Code: | | {nocache}{foreach...}{include} {/foreach} |
Is wrong as {include} is now inside the nocache section and all includes are executed in nocache mode.
It's currently not possible to make the nocache flag variable because of all the compiling and caching procedures.
An other important note: when caching is on and $section.template can have same name with different data in $section you must use some unique data as 'cache_id' otherwise you will get just the first page displayed.
like
| Code: | | {foreach...}{include file=$section.template cache_id=$section.somename} |
