How do I make my radio buttons checked - php

Question

I have a table, that generates rows dynamically. I have used radio buttons for each row. I want the radio button to be checked even after I click my submit button.
This is body of my table:
<form action="" method="POST">
<table>
<thead>
<tr>
<td></td>
<td><h3>Date<h3></td>
<td><h3>Status<h3></td>
</tr>
</thead>
<tbody>
<?php for($i=$start;$i<$end;$i++)
{
$add=$ARRAY[$i]['source_address'];
$Status=$ARRAY[$i]['Status'];
$total=$add.$Status;
?>
<tr>
<td><input type="radio" name="ID[]" value="<?php echo $total; ?>"/></td>
<?php
echo'<td>'.$ARRAY[$i]['escl_date'].'</td>';
echo'<td>'.$ARRAY[$i]['escl_status'].'</td>';
?>
</tr>
<?php }?>
</tbody>
</table>
<input type="submit" name="details" value="details" />
How Can I make the radio button selected even after clicking on submit button? Please help me.

Answer 1

You can try this, You need a condition to check with reference value and add checked attribute.
Here your reference value is your POST of ID value. Add this into your radio tag <?php echo $_POST['ID'][0]==$total ? 'checked':'';?>
<input type="radio" name="ID[]" value="<?php echo $total; ?>" <?php echo $_POST['ID'][0]==$total ? 'checked':'';?> />

Answer 2

The correct HTML attribute you are looking for is checked.
Note to other answer: readonly is not necessary, nor is it what OP is asking for.
Since you're doing it in PHP, let's say you're passing something with an HTML markup name of foobar, as follows:
<form><input type="radio" name="foobar"></form>
To make sure that the value is retained even after it is submitted, you could add a code like this (get or post depending on your purpose):
<form><input type="radio" name="foobar" <?php if(isset($_GET[foobar])){ echo "checked"; ?>></form>
This is to make sure that it would be checked if the name was passed in the form.
Note that this is just an example.

Try this, it works:
<input type="radio" checked>
