JQuery

$(document).ready(function() {

        $("#export").click(function(){

            var selectedvalues = [];

            $.each($("input[name='checkedvalues']:checked"), function(){

                selectedvalues.push($(this).val());

            });

            alert("Checked values are: " + selectedvalues.join(", "));

        });

    });

now i am getting only the values of selected checkbox which infact i dont want what i want is to generate an array which should be populated on the basis of checked attributes! it should take the full row on the basis of which checkbox is checked and then return me an array with all rows which are checked, any help?

Answer 1

You can store the row data as an object in "value" in each checkbox. Something like below (inside your foreach loop)

foreach($results as $r){
        $obj = "{".$r['brand'].",".$r['production_date'].",".$r['expiry_date'].",".$r['madein'].",".$r['status'].",".$r['batch_code'].",".$r['created_on']."}";
        echo "<tr>";
        echo "<th id='not2'><input type='checkbox' name='checkedvalues' value='".$obj."'/> </th>";
        ...
        ...
}

Now, your selectedvalues array will have javascript objects with each checked row.

p.s sorry for any php syntax errors
