For the following form and using inputs type Select with Values that are part of an array, I must pass them by $ POST to a DB, with the conditional that if they are not passed in the specified order mark error and indicate the Values of the Select that mark this error.
The order I have proposed, in this case is:
For "STORE_1" it must correspond with "BODEGA_1". For "STORE_2" it must correspond with "BODEGA_2". For "STORE_3" it must correspond with "BODEGA_3". For "STORE_4" it must correspond with "BODEGA_4".
I have placed in the select, the default values, some change in them should mark error and tell me only the values that have changed, passing through $ POST.
