Validating multiple checkboxes using javascript

29 Apr

Unfortunately, when checking the value in javascript, all radios must be evaluated individually (I do this in a loop).In an unrelated matter I just realized that since I changed all the color input names to 'colors[]', that makes their validation a little simpler.But it also means that the values you are looking for in the receiving page or process will have these new names.Instead of I did say that my PHP knowledge was limited.Here's my jquery code: have a "name" property, or else they will not be added to the array. UPDATE (May 2013) Moved the submit registration to javascript and registered the submit onto the form (as it should have been originally) UPDATE (June 2016) Changes == to === The above add Method by Lod Lawson is not completely correct.

(f['gender[1]'].checked == false); why is it not working.i think because of that (f) my other validation code is not working. if i comment the gender field validation then everything works fine. With a pair of radio buttons, one will always be false, and there is no gender[0] or gender[1]. Even in PHP, with radio button groups, only the value of the checked radio button is passed, that's why they can all have the same name with no .In our previous tutorials, we have performed various operations on different form elements using Javascript and j Query.In this tutorial, our concern is to get values of multiple checked checkboxes using PHP as follows: To get value of a checked checkbox : In our example, there is a form contains some checkboxes, User checks them and when he/she hits submit button, multiple values of checkboxes will be display.
