How do I emit curly braces while working with Smarty?

By default Smarty considers curly braces as delimiters for its own compilation.

So, if you want to have a JavaScript code, as given below, in the template file:

<script language='javascript' type='text/javascript'>
    function doWork() {
        var obj = { name: 'Edujini FAQs',
                    url: 'http://faqs.edujini-labs.com' };
        alert(obj.name + ' => ' + obj.url);
    }
</script>

Smarty will complain about invalid types or keyword "{ var" etc because it considers anything within curly braces as a code for execution.

There are multiple solutions to this problem, though trivial but encountered several times:

• Use literal text: http://www.smarty.net/manual/en/language.function.literal.php
• Use delimiters: http://www.smarty.net/manual/en/language.function.ldelim.php

Simplest solution is to include your entire content within a literal block.

{literal}
<script language='javascript' type='text/javascript'>
    function doWork() {
        var obj = { name: 'Edujini FAQs',
                    url: 'http://faqs.edujini-labs.com' };
        alert(obj.name + ' => ' + obj.url);
    }
</script>
{/literal}

In the second option, you may emit out ldelim / delim functions or directly left_delimiter / right_delimiter variables. The usage is demonstrated in the code below:

<script language='javascript' type='text/javascript'>
    function doWork() {ldelim}
        var obj = {ldelim} name: 'Edujini FAQs',
                    url: 'http://faqs.edujini-labs.com' {rdelim};
        alert(obj.name + ' => ' + obj.url);
    {rdelim}
</script>

<script language='javascript' type='text/javascript'>
    function doWork() {$left_delimiter}
        var obj = {$left_delimiter} name: 'Edujini FAQs',
                    url: 'http://faqs.edujini-labs.com' {$right_delimiter};
        alert(obj.name + ' => ' + obj.url);
    {$right_delimiter}
</script>

And you are ready to go....
