The {echo:} dynamic tag is a powerful feature in Bricks. With it, you can easily execute your desired functions or transform data on the frontend.
However, issues may arise when using {echo:} with dynamic parameters.
Instead of passing parameters to your custom PHP function, I suggest using the bricks_render_dynamic_data function (@since 1.5.5) within your PHP function.
Here’s an example:
Let’s say we have a custom function that says “Hi” if field A is ‘yes’, otherwise it says “Hello” to field B:
// Say Hi if field A is 'yes', otherwise say Hello to field B
function conditionally_say_hi( $field_a, $field_b ) {
if ( $field_a === 'yes' ) {
return 'Hi';
} else {
return 'Hello ' . $field_b;
}
}Inside the builder, we would use {echo:conditionally_say_hi( {acf_field_a}, {acf_field_b} )} .
However, sometimes you may get unexpected results, such as incorrect values or parameters.
To solve this, you can easily modify your function like this and use {echo:conditionally_say_hi} directly inside the builder:
// Say Hi if field A is 'yes', otherwise say Hello to field B
function conditionally_say_hi() {
$field_a = bricks_render_dynamic_data( '{acf_field_a}' );
$field_b = bricks_render_dynamic_data( '{acf_field_b}' );
// You can get more parameters as you like
if ( $field_a === 'yes' ) {
return 'Hi';
} else {
return 'Hello ' . $field_b;
}
}
By doing this, you won’t need to pass too many parameters from the builder and clutter your fields. Additionally, you’ll only need to change the conditionally_say_hi function in your script, which can include adding or changing parameters, without the need to change every field inside the builder.
