I am using radio buttons to sort through paginated results. However, whenever the button is clicked and auto-submitted, it becomes unselected. I want to keep the button selected so that the user knows which one they selected. How can I do that?
Here is what I have:
function autoSubmit() {
var formObject = document.forms['theForm'];
formObject.submit();
}
<input type="radio" name="sort" value="time" onChange="autoSubmit();" />
<input type="radio" name="sort" value="year" onChange="autoSubmit();" />
<input type="radio" name="sort" value="name" onChange="autoSubmit();" />
if(isset($_GET["sort"])) {
$sort = $_GET["sort"];
}
I presume that your code is something like this:
<?php
$sort = "";
if(isset($_GET["sort"]))
{ $sort = $_GET["sort"]; }
?>
<html>
<head>
<script>
function autoSubmit()
{
var formObject = document.forms['theForm'];
formObject.submit();
}
</script>
</head>
<body>
<form name='theForm' id='theForm'>
<input type="radio" name="sort" <?php if ($sort == 'upload_time') { ?>checked='checked' <?php } ?>value="upload_time" onChange="autoSubmit();" />Recently Uploaded
<input type="radio" name="sort" <?php if ($sort == 'article') { ?>checked='checked' <?php } ?> value="article" onChange="autoSubmit();" /> Alphabetically
<input type="radio" name="sort" <?php if ($sort == 'year') { ?>checked='checked' <?php } ?> value="year" onChange="autoSubmit();" /> Most Recent
</form>
</body>
</html>
Do this server-side. Set the attribute checked="checked" in the radio button that is selected.
