 Posted: Wed Feb 25, 2015 9:22 pm Post subject: Use Smarty assigned variable in Smarty assigned variable |
 |
|
| Is it possible to assign a variable (e.g. $smarty->assign('myVar','Hello World')) and then use that in another assign $smarty->assign('someVar','This should print {$myVar}!') and have that actually output 'This should print Hello World!'? |

The content of assigned variables is not parsed for Smarty tags.
But in this example you could use the replace modifier in your template.
| Code: | | {$someVar|replace:'{myVar}':$myVar} |

| I think, better answer would be "You're doing it wrong, please rethink your goals and methods." |

The issue is the replacement isn't in the template. I have a template that loops over an array and in this assigned array I have the text that will populate in the template. The text I want to be used as the replacement has already been assigned and is used in other templates or sections and I was trying to reduce repetitive code and make it easier for my non PHP/HTML editor to be able to output the desired content and {$myVar} is much easier to put in for less skilled person who doesn't understand full PHP/HTML.
Maybe an explanation through sample.
| Code: |
$smarty->assign('state',array('full'=>'California', 'abrv'=>'CA'));
$smarty->assign('examples' ,array(
'example', array(
'a'=>'I am from {$state.abrv}',
'b'=>', also known as {$state.full}
),
'example', array(
'a'=>'I have lived in {$state.full} for 20 years. ',
'b'=>'I like the weather in {$state.abrv}'
),
)
);
|
Template file:
| Code: |
<div class="block">
{foreach $examples as $example}
<li>{$example.a}{$example.b}</li>
{/foreach}
</div>

| Remove second assignment. Use included templates. |

In my particular project I can't. The loop is generated from an array of questions that are static with the exception of the replacement value. In these items I need to replace a keyword with a value being passed through $_GET. |

| Do note you're contradicting yourself. |

Had I looked at this closer the first time I would have had my answer. I didn't put it into context with where I needed to use the code snippet.
Thanks U.Tews. |
