Hello Team,

Hope you all are doing well.
Here is a case:

Templates/php_app.conf.j2

;# MANAGED BLOCK ###
php_admin_flag[display_errors] = {{server_config.display_errors}}
php_admin_value[error_log] = {{ server_config.error_log | default({“error_log”:“{{base_directory_path }}/{{app_name}}/logs/php-fpm_error.log”}) }}
php_admin_flag[log_errors] = {{server_config.log_errors}}
php_admin_flag[short_open_tag] = {{server_config.short_open_tag}}
php_admin_value[memory_limit] = {{server_config.memory_limit}}
php_admin_value[post_max_size] = {{server_config.post_max_size}}
php_admin_value[upload_max_filesize] = {{server_config.upload_max_filesize}}
php_admin_value[max_input_time] = {{server_config.max_input_time}}
php_admin_value[max_execution_time] = {{server_config.max_execution_time}}
php_admin_value[max_file_uploads] = {{server_config.max_file_uploads}}
php_admin_value[max_input_vars] = {{server_config.max_input_vars}}
php_admin_value[date.timezone] = {{server_config.time_zone}}
;# MANAGED BLOCK ###

You need one more “}” on your -e string to close out the server_config.

ansible-playbook php_config.yml -i hosts -e ‘{“app_name”:“test-80php”,“base_directory_path”:“/var/www/html/applications/test-80php”,“server_config”:{ “display_errors”:“Off”, “log_errors”:“On”, “memory_limit”:“200M”, “post_max_size”:“8M”, “upload_max_filesize”:“8M”, “max_input_time”:“60”, “max_execution_time”:“30”, “max_file_uploads”:“20”, “max_input_vars”:“2000”, “short_open_tag”:“On”, “time_zone”:“Asia/Karachi”} }}’ -vvv

That clearly didn’t display correctly …

You need three close braces at the end of your “-e” extra vars param.

} }}’ -vvv

Hope that helps.

Here is the command previously used, I hope it is clearly visible.

ansible-playbook php_config.yml -i hosts -e ‘{“app_name”:“test-80php”,
“base_directory_path”:“/var/www/html/applications/test-80php”,
“server_config”:{“display_errors”:“Off”,
“log_errors”:“On”,
“memory_limit”:“200M”,
“post_max_size”:“8M”,
“upload_max_filesize”:“8M”,
“max_input_time”:“60”,
“max_execution_time”:“30”,
“max_file_uploads”:“20”,
“max_input_vars”:“2000”,
“short_open_tag”:“On”,
“time_zone”:“Asia/Karachi”}}’ -vvv

Walter, I have tried adding more braces, but unfortunately, it didn’t work for me.
The number of openings and closings braces is the same.

Mustaches do not nest. The “error_log” line in templates/php_app.conf.j2 should be

php_admin_value[error_log] = {{ server_config.error_log | default(base_directory_path ~ "/" ~ "app_name/logs/php-fpm_error.log") }}

Thanks, Lewis for the solution. It actually worked. But would you mind explaining or sharing the documentation of what you have done above inside the “default()”?

I actually want to learn and understand this.

Thanks & regards,
