i am working on codigniter . i am developing basic cms.my view code of generating dynamic pages at front end is

<ul id="jsddm">
<?php for ($i=1; $i<=$url['10']['10']['10']; $i++)
{ ?>
    <li><a href="<?php echo site_url($url[$i]['0']['slug']); ?>"> <?php echo $url[$i]['0']['page_name']; ?> </a>
                  <?php if($url['11'][$i]['11']>0){ ?>
        <ul>
                        <?php for ($j=1; $j<$url['11'][$i]['11']; $j++) { ?>
            <li><a href="<?php echo site_url($url[$i]['0']['slug'].'/'.$url[$i][$j]['slug']) ?>"><?php echo $url[$i][$j]['page_name']; ?></a></li>
                    <?php } ?>
        </ul>
                 <?php } ?>
</li>
<?php }?>
</ul>

It is giving the error

A PHP Error was encountered

Severity: Notice

Message: Undefined offset: 9

Filename: includes/website_header.php

Line Number: 85

AND

A PHP Error was encountered

Severity: Notice

Message: Undefined offset: 9

Filename: includes/website_header.php

Line Number: 86

the 86th line is if statement.

Sounds like the array doesn't have an index with value 9. Try changing line 5 above to:

<?php if(isset($url['11'][$i]['11']) && $url['11'][$i]['11']>0){ ?>

And if you're using PHP conditional statements inline with HTML, I find the following statements easier to read than tracking brackets:

<?php if(true): ?>
    <!-- Your HTML here -->
<?php endif; ?>

<?php for($i = 0, $count = count($array); $i < $count; $i++): ?>
    <!-- Your HTML here -->
<?php endfor; ?>

<?php foreach($array as $key => $value): ?>
    <!-- Your HTML here -->
<?php endforeach; ?>

Yes,The problem of line 86 has been solved thanks for it but the problem of line 85(which is fourth line of the above code) is remaining.....

ok
