php - How can I get form_ID field from table before inserting the options? -

i have 3 tables on database,

·form_id
·active

form_options

·form_id
·option

form_results

·form_id
·option_selected
·ip

when Ι create poll Ι need associate options created new form, Ι don't want insert first form_id field on form table, after selecting last form_id on form , inserting id on form_id on form_options table. when sending form, want new form_id on form_options same form_id on form in 1 step.

that say, should know newly created form_id on form insert same in form_id on form_options table.
