[PHP] PHP Form and Arrays help
I'm having a small problem with a form I'm designing and I hope someone can point me in the right direction here. The form's function is rather simple actaully. It's supposed to take the information, run through it to make sure all the required fields have data in them, if there is a blank required field it is supposed to redraw the form showing the field missed but also store the data that was already submitted so you don't have to fill the form out all over again. Now I have it so it stores the values of text boxes, drop down menus and radio buttons but I'm having a real tough time with the check box values. Example of what I'm doing: (Gender Selection with Radio Buttons). I declare an array in my PHP by doing $genderarray=array(); Then I store the value of the form for the redraw like so: $mygender=$HTTP_POST_VARS[gender]; $genderarray[$mygender]=checked; In the actaul form I decalre a global: global genderarray(); And under the gender selection I have: input name=gender type=radio value=Male ?= $genderarray[Male] ? (works the same for the Female) Now my question is how can I do this with check boxes. I thought I could through them all into a single array, then pull out the ones who have values to them, but that's not working the way I thought.

Use either session to remember the checkboxes' name/value pairs or hidden fields.

If I remember correctly checkboxes literally do not exist on the posted pages if they don't get checked on the form page. So maybe you can use isset or something like that to see if the checkbox exists if so make it checked if not show it unchecked. Hope that helps.
