Place a onCLICK inside a PHP echo - php

Question

I have the following code
<table width="100%" border="1" cellpadding="15" align="center">
<?php
$res = $dbcon->query("SELECT * FROM actor");
while($row=$res->fetch_array())
{
?>
<tr>
<td><?php echo $row['actor_id']; ?></td>
<td><a href="?del=<?php echo $row['actor_id']; ?>" onclick="return confirm('sure to delete !'); " >delete</a></td>
</tr>
<?php
}
?>
This works fine in every way but the problem is that i cant seem to set the onclick to work onside an echo in this next piece of code.
I'm learning mysql/php so i'm experimenting with various codes.
FOR ($j=0 ; $j < $rows; ++$j) {
$result->data_seek($j);
$row = $result->fetch_array(MYSQLI_ASSOC);
echo 'Actor ID: ' . $row['actor_id'] . '<br>';
echo 'Delete'. '<br><br>';
}
$result->close();
$conn->close();
?>
The delete button works i just don't have a warning anymore, i can't figure out
how to properly insert onclick="return confirm('sure to delete !')

Answer 1

You will have to escape the quotes. This is what you need
echo 'Delete'. '<br><br>';

Answer 2

If you use PHP for templates maybe you should consider more template oriented syntax
<?php while($row=$res->fetch_array()): ?>
<tr>
<td><?= $row['actor_id'] ?></td>
<td><a href="?del=<?= $row['actor_id'] ?>" onclick="return confirm('sure to delete !'); " >delete</a></td>
</tr>
<?php endwhile ?>
It will make escaping a lot easier.

Yo can make it in another way:
<td><a class="delete" href="?del=<?= $row['actor_id'] ?>" >delete</a></td>
<script>
$(document).ready(function){
$('.delete').click(function(){
var id = $(this).attr('del');
var confirmText = "Are you sure you want to delete this object?";
if(confirm(confirmText)) {
$.ajax({
type:"POST",
url:url,
data: 'id=' + id,
success:function () {
// Here goes something...
},
});
}
return false;
});
});
</script>
