@empty - Checking If a Variable Is Empty

The @empty directive in Ahmed PHP Template Engine is used to check whether a variable is empty (i.e., it is not set, null, false, or an empty string/array). This helps in conditionally displaying content based on the absence of a value.

Syntax

@empty(variable)
    // Code to execute if variable is empty
@endempty

• variable is the variable being checked.

• The enclosed block of code executes only if the variable is empty.

Example

@set(message, '')

@empty(message)
    <p>No message available.</p>
@endempty

Output

<p>No message available.</p>

Notes

• @empty is useful for handling cases where a variable may be unset or contain an empty value.

• If the variable has a value, the enclosed block is skipped.

• Can be combined with @isset for advanced conditional checks.
