php - Get array elements dynamically based on checkbox checked? -

i've got problem can't solve. partly because can't explain right terms. i'm new sorry clumsy question.

below can see overview of goal.

i have products along check boxes.if checked check box index value should store in new array(should perform push() operation here),if in case again unchecked check box means should perform pop() operation.

<form method="post"> <input type="checkbox" name="options[]" value="politics"/> politics<br/> <input type="checkbox" name="options[]" value="movies"/> movies<br/> <input type="checkbox" name="options[]" value="world "/> world<br/> <input type="submit" value="go!" /> 

may 1 duplicate question give me sorry

any ideas ?

you're using check-boxes, can't use pop, since might unchecked in different order.

so maybe use jquery store link javascript object on dom check-box object using .data() way can match object later using loop , use .splice() remove array.

edit 1: want validate state of check-box?

if (document.getelementbyid('mycheckbox').checked){           myarray.push(data); }
