[shaddf]

i have a set of selects in html form and would like to validate them based on :

if the first select is not null and the value is not equal to the selection of the second select,and the remaing selects are not empty or null,then pass else fail.

how can i do that? here is my html

you should validate each input separately and set up a specific error message for each input so that the user doesn't need to guess which value(s) was(were) not selected. you would validate any empty values first, before testing if the first two values are not the same.

 

if you use an array of arrays to hold the error messages, with the main array index being the key/section value (0, 1, 2, ...) and the secondary array index being the select name, you can either output all the errors as a group at the start of each section or you can output each individual error at the select menu it corresponds to.

 

you would also want to validate all the sections of data at once (no break; in the loop) so that you could display all the errors at once. by breaking out of the loop upon the first error, the user will have to fix the error(s) with one section before seeing if there are more errors later in the submitted data.

 

if you set up an array that defines the form fields and the label for each, you can use this to produce your table heading and to dynamically validate the data and dynamically set up the error messages.

 

i also hope you are dynamically producing the select menus, which would allow you to select any existing option choices should there be validation errors so that the user doesn't have to re-select everything when there is a validation error.

could you tweak the code to this end .
