Regarding the add custom field in posting and edit the project. You could use the AE Custom Fields plugin to do that.
Regardless, here’re some suggestions that you can refer to implement this.
- Chek code in template/post-project-step3.php file or use the hook ae_submit_post_form to add new field into posting form.
- Use the hook ae_insert_project and ae_update_project to save the new field or edit field.
- Check code in template-js/modal-edit-project.php file or use the hook ae_edit_post_form to add new field in edit project form.
That is what I can give you for referencing thus far. I will notice to our developer to consider and improve our technical documentation soon.
Thank you for your time!
