PHP Notice: Undefined index How To Fix This

Question

i am getting PHP Notice: Undefined index error in my site.

PHP Notice: Undefined index: title in /home/kashan/public_html/ifunnygag.com/templates/wlol_v1/pages/header.php on line 41 [15-Apr-2013 06:36:42] PHP Notice: Undefined index: url in /home/kashan/public_html/ifunnygag.com/templates/wlol_v1/pages/header.php on line 42

var opts = {
Line 40 message : '<?php echo $file['title'];?>',
Line 41 name : '<?php echo $file['title'];?>',
Line 42 link : '<?php echo $file['url'];?>',
    description : 'Click to see pic...',
Line 44 picture : '<?php echo $file['path'];?>'

};

FB.api('/me/feed', 'post', opts, function(response)
{
    if (!response || response.error)
    {
        console.log(response);
    }
    else
    {
        console.log('Success - Post ID: ' + response.id);
    }
});

}

Or $file is set, but $file['url'] is not? best way to settle that question: please add `print_r($file);` and let us know if $file is empty.. — asifrc, Apr 15 '13 at 12:57

If you want to leave the values empty if they are not set then use like

<?php echo isset($file['title'])?$file['title']:"";?>

First of all check your $file array should have those indexes which u trying to echo, if it is there then do like this

"<?php echo $file['title'];?>"

You can check variables and array indexes using isset() or empty() before using them. I.e.

if (empty($file['url'])) {
 $file['url'] = '';
}

But you may also want to make sure that it isn't empty due to some other serious problem. I.e. Post fields that are not validated properly before being accepted. If a required post field is empty, you might want to reject the post request entirely.

Check if the quotes are causing the problem. Try,

"<?php echo $file['title'];?>"
