As for how to configure it, there is no need to say more here, there are a lot of them online.
1. Basically the most important methods to be used are the assign and display methods.
2. Basically the knowledge to be used on the page is if, foreach and section.
3. Basically the most difficult ones are foreach and section.
4. When I first started learning, I always couldn’t loop through the data I wanted. Because it still feels a little different from foreach and for in php, java, etc. It's hard to catch his activity path and hard to debug his data.
5. So here, I put out a little bit of sutra chanting:
If the data is like this:

Copy code The code is as follows:

array(0=>array('id'=>'1111','content'=>'2222')); Then the foreach loop
{ {foreach from=$exam item=item key=k}}
{{$item.content}}
{{/foreach}}

is fine, but if array('id'=>'1111','content'=>'2222') In this way, you cannot loop like this, you need to do this:

Copy code The code is as follows:

{{foreach from=$exam item=item key=k}}
{{if $k eq 'content'}}
                       {{ $item}}
{{/if}}
{{/foreach}}

If you don’t know what eq means here, you can search it online. I will give this below Let’s briefly list:
eq is equal,
ne and neq are not equal,
gt is greater than,
lt is less than,
gte and ge are greater than or equal to,
lte and le are less than or equal to,
not non, mod is used to find the modulus.
is [not] whether div by is divisible by a certain number,
is [not]even whether it is an even number,
$a is [not] even by $b, that is ($a / $b) % 2 == 0，
is [not] odd whether it is odd

6. If you want to use php code in the smarty template, like this:
{{php}}$a = "gayayang"; echo $a;{{/php}}
This way you can use php code in the template.

7. Quote files in smarty:
You can use the above method: {{php}}include "config.php";{{/php}}
Or be more professional :{{include file="config.php"}}
Both methods can be implemented. The following ones are more professional and recommended.

8. There is such a method: $smarty->fetch("mytemplate.html");
Fetch and display are both used to render templates. fetch can convert the rendered The entire template is assigned to a variable in the form of a string, which can be used to generate a static page using

Now you know how to use this. It can return the content of the file to a variable, so this is very useful. Haha
Using the fetch function, you can assign the html to be output to a variable, and then output some of the data inside.
The display method in smarty actually calls fetch, which just displays it directly. However, fetch does not display it by default and returns it to a variable.

That’s basically it. I’ll write more if I add more in the future. Haha
