@isset - Checking If a Variable Is Set

The @isset directive in Ahmed PHP Template Engine is used to check whether a variable has been defined and is not null. It allows conditional rendering based on the presence of a variable.

Syntax

@isset(variable)
    // Code to execute if variable is set
@endisset

• variable is the variable being checked.

• The enclosed block of code executes only if the variable exists and is not null.

Example

@set(name, 'Ammar')

@isset(name)
    <p>Hello, {{ name }}!</p>
@endisset

Output

<p>Hello, Ammar!</p>

Notes

• @isset is useful for ensuring variables exist before displaying them.

• If the variable is not set, the enclosed block is skipped.

• Can be combined with @else or @empty for alternative behavior.
