What are the Smarty template functions

This article is to share with you about the Smarty template function, the editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article. Let's take a look at it.

Recently, I used Smarty template engine in my work and sorted out some template functions used.

Assume that the delimiter of smarty is {}.

Get the value of server $_ GET from the template:

{$smarty.get. Parameter name}

Get the value of server $_ POST from the template:

{$smarty.post. Parameter name}

Get the value of server $_ REQUEST from the template:

/ / request can get the value of get or post. {$smarty.request. Parameter name}

Get the value of server $_ SESSION from the template:

{$smarty.session. Parameter name}

Get the value of server $_ COOKIE from the template:

{$smarty.cookies. Parameter name}

Get the value of server $_ SERVER from the template:

{$smarty.server. Parameter name}

Convert the timestamp to Y-m-d H:i:s in the template:

{$Parameter name | date_format:'%Y-%m-%d% HRV% MRO% S'}

Convert the string to lowercase in the template:

{$Parameter name | lower}

Convert the string to uppercase in the template:

{$Parameter name | upper}

Convert the first letter of the string to uppercase in the template:

{$Parameter name | capitalize}

Add characters to the template after the string:

{$parameter name | cat:' string'}

Set the default value in the template if the variable is empty or does not exist:

{$parameter name | default:' string'}

The length of the string in the template is more than 20 and is hidden behind. Connection:

{$Parameter name | truncate:23: "...": true}

Convert the HTML in the string to HTML encoding in the template:

{$Parameter name | escape:html}

Convert the HTML in the string to URL encoding in the template:

{$Parameter name | escape:url}

Replace characters with regular expressions in the template:

{$Parameter name | regex_replace: "/ string 1 /": "string 2"}

Use Replace to replace characters in the template:

{$parameter name | replace: "string 1": "string 2"}

Formatted numbers in the template are of type Float (rounding retains two decimal places)

{$Parameter name | string_format: "% .2f"}

The formatted number in the template is of type Int (if there is a decimal place, it will be dropped)

{$Parameter name | string_format: "% d"}

If the {} of js conflicts with the smarty delimiter:

(1) modify the delimiter to (2) to include the JS code between {literal} {/ literal}. These are the Smarty template functions, and the editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article.
