Php Smarty template - assigning complex content to variables

In some cases Smarty doesn't allow you to assign values to variables just like that. For example in foreach loops. Then the following solutions can work. 1, Assign a simple text with variables:

explanation: Smarty's smart enough to replace value of variable within quotes.

2, Assign special characters or longer text:

explanation: the capture tag allows you to add text without quotes so it's readable. Variables have to be in {}.

3, Do ternary operation and assign value:

explanation: need to be aware of the brackets, but works fine. Normal brackets contain the condition.

Ternary operator concatenate variables with string (if the parentname is set, concatenate variables to a new string)

Smilyan Pavlov

Designer & web strategy consultant in sheffield, uk, smarty – how to assign a variable into a variable in the template.

Recently I needed to assign several variables into one smarty variable inside the template.

Here is the basic rules for the example:

You have a text that says “Your registration expires in # days”;
You want The text “in # days” to change to “today” if the # days is 0.

Here’s a way you can do this with smarty variables inside the template (whether you should do this in the template is not a discussion for this post).

The key here is that when you want to include a variable as part of the value of another variable you need to use value=” $in_days “ . Notice the ` before and after the variable name inside the double quotes. You can use this method to include variables inside value statements anywhere in smarty templates and make modifications of those included variables.

One thought on “ Smarty – How to assign a variable into a variable in the template ”

That helped a lot. Thanks!

assign() — assign variables/objects to the templates

Description

You can explicitly pass name/value pairs, or associative arrays containing the name/value pairs.

If you pass the optional third nocache parameter of TRUE , the variable is assigned as nocache variable. See Cacheability of Variables for details.

When you assign/register objects to templates, be sure that all properties and methods accessed from the template are for presentation purposes only. It is very easy to inject application logic through objects, and this leads to poor designs that are difficult to manage. See the Best Practices section of the Smarty website.

Example 14.6. assign()

These are accessed in the template with

To access more complex array assignments see {foreach} and {section}
