passing values between javascript and PHP

[zedan_80]

Hallo

i m using an array of check boxes and i want pass them to javascript to check them if 1 of them at least checked submit the form or alert error msg

so how can i pass the array to javascript?

u dont need php for that at all... google for "DOM" and checking the states of check boxes

all check boxes gets value from PHP qry so when i need to delete an item by checking it box i wanna know which item get check so i will alert the user if he wants to delete that item

right... heres what i'd do

sooo... have checkboxes next to each item that can be deleted, then have a button called delete or w/e...

now u can proceed in two ways.. one using JS and one using PHP

if you wanna use JS, for your delete button have an "onclick" event trigger that will call JS to check the checkbox array and tell you which are "checked", from there you can make a popup conveying this information... and then once confirmed use a JS redirect using a query string to execute the deletion

if you wanna use php, just have the post/get variables transfer over, and have php check them... for a checkbox, i beleive if it is checked that value returned is "true" (havent done much form+php in a while) and from there have php make a confirmation page

this is kinda common... google around a bit 🙂 im sure youll have no problems
