Implementation code for similar for loop functions in smarty templates

{section name=total loop=100}
{$smarty.section.total.index+1} //Current index
{$smarty.section.total.iteration} //Used to display loops Times
{/section}

You can also do this:

{assign var=i value=0}
{section name=total loop=100}
{assign var=i value=$i+1} {$i} //Assign using assign method
 {/section}

Output results: 1 2 3 4 5 ... ... 100

In addition, let’s introduce how to use php functions in smarty.

In the smarty template, if you use the php function, a function with only one parameter, such as removing blank trim, can be written like this: example 1:

<{$colname|trim}>

So what should I write if I use a function with three parameters like iconv? If written: Example 2:

<{$colname|iconv:'utf-8':'gbk'}>

You will find an error message displayed as soon as you execute it. Starting from the application function usage on the smarty template page, taking Example 1 as an example, the $Row->colname in front of trim is actually the first parameter of trim, and is concatenated with the symbol | in the middle; If you want to use a function with three parameters like iconv, you should write: Example 3:

<{'utf-8'|iconv:'gbk':$colname}>

That is, the first parameter of the function | function: the second parameter: the second parameter three parameters. In Example 3, the value of colname will be converted from utf-8 format to gbk.
