i wan't to get the data on the same row where a checkbox is checked. please help me. thanks

Answer 1

You have to loop through the POST data, and assign $r[NAME] = VALUE
For the PHP code:
array $r;
foreach($_POST as $post=>$value) {
//get the html data beside the checked checkboxes
$r[ $post] = $value;
}
}
}else{
echo '<script language="javascript">';
echo 'alert("Nothing checked")';
echo '</script>';
}
Assuming that the HTML part your referring to is the result page
For the HTML:
<tr>
<td><?php echo $r['Name'] ?></td>
<td><?php echo $r['Age'] ?></td>
<td><?php echo $r['Address'] ?></td>
</tr>

First, lets add some data:
<?php
$data = [
'111' => [
'Name' => 'John',
'Age' => '25',
'Address' => 'Baker street, 11'
],
'222' => [
'Name' => 'Mary',
'Age' => '19',
'Address' => 'Elm street, 14'
],
'333' => [
'Name' => 'Nick',
'Age' => '23',
'Address' => '64th stree, 2'
]
];
?>
Output all data items and set checks from previous posted data:
<form method="POST">
<table>
<?php foreach($data as $id => $item): ?>
<tr>
<td><?= $item['Name'] ?></td>
<td><?= $item['Age'] ?></td>
<td><?= $item['Address'] ?></td>
<td><input name="check[]" type="checkbox" value="<?= $id; ?>"
<?php if (isset($_POST['check']) && in_array($id, $_POST['check'])): ?>
checked="checked"
<?php endif; ?>/></td>
</tr>
<?php endforeach; ?>
</table>
<input type="submit" />
</form>
<?php if (empty($_POST['check'])): ?>
<script>alert("Nothing checked");</script>
<?php endif; ?>
You'll get reloaded page with properly marked checkboxes after the form submission.
