HTML中的多个隐藏字段

Question

I am creating a popup dialog box where I need to put a set of values in hidden format, but when I am getting the value in AJAX post, I am getting only last value.

this is the PHP part:

$plan_ids=array();
foreach($test_plan as $plan)
{
    $plan_ids[]=$plan['plan_id'];
}
?>

<?php
foreach($plan_ids as $id)
{
    echo "<input type='hidden' id='plan_id' value='$id'>";
}
//var_dump($plan_ids);
// echo $plan['plan_id'];
?>

In the AJAX part I am doing:

$("#save").click(function () {
    var name = $('#name').val();
    var id = $('#release_id').val();
    var plan_id = $('#plan_id').val();
    //alert('hello');
    $.ajax({
        type: 'POST',
        url: '/api/api.php?action=put_iteration&name=' + name + '&id=' + id + '&plan_id=' + plan_id,
        data: "name=" + name + "&id=" + id + "&plan_id=" + plan_id,
        success: function () {
            $('#save').hide(function () {
                $('div.success').fadeIn();
            });
        }
    });
});

I'm clueless about HTML hidden fields.

Answer 1

you can name all your hidden fields like an array name="plan_id[]"

And instead of passing it as a string you can have a wrapping FORM around hidden fields and then use jquery serialize function to POST it

Now you will get all the plan_id in the form of an array in the POST variable

Adding an example

<?php
echo '<form name="planidform" id="planidform">';
foreach($plan_ids as $id)
{
    echo "<input type='hidden' name="plan_id[]" value='$id'>";
}
echo '</form>';
?>

After than in jQuery do it in following manner:

data: "name=" + name + "&id=" + id + "&"+$("#planidform").serialize(),
