you should check if the variable is filled upfront, using isset() :

if(isset($data->field_field_exp_thumbvideo[0]['rendered']['#markup'])){
return $data->field_field_exp_thumbvideo[0]['rendered']['#markup'];
}
else {
return 'no video';
}

see also #1264630: What would be the correct code to test the value of a field ?

This behavior is still present in the current version.

Some explaining in the description would be helpful. Now it only mentions $row-> but this doesn't really work, so how are people supposed to know the way to handle $data-> when using your module?

P3t3r, I would consider this module broken, #1140896: Variable $row does not contain correct values ($data->_field_data does) suggests workarounds.

The module may be broken, but I'm not aware of any other modules offering such functionality.
I got here from this topic which discusses a problem very similar to mine. Do you know any other modules that could make this work?

PS: this is the exact thing I want to do if it matters. Just like the other topic I see no way to do it without this module. It are both very standard things to do and yet it needs a module which has open bugs of over a year old. :(

Marking #1496586: Sort error as a duplicate of this tread.

I got:
Notice: Undefined variable: output in __lambda_func() (line 34 of /DRUPAL7/sites/all/modules/contrib/views_php/plugins/views/views_php_handler_field.inc(202) : runtime-created function).

Using 7.x-1.x-dev (2012-Feb-21) & Views 7.x-3.5.

#1 work for me.

I am getting this error as well, and #1 is not working for me.

Notice: Undefined offset: 0 in __lambda_func() (line 5 of /sites/all/modules/views_php/plugins/views/views_php_handler_field.inc(202) : runtime-created function).

It occurs because one of my fields, field_description, is optional and sometimes has no value. I attempted to use if, if/else, if(isset), !empty, etc. in order to hide "empty" fields and remove the error message. The view displays exactly how I need, but the error is always there.

Is there a fix to this problem?

After doing a lot of trial and error, I finally decided to scrap what I was trying to accomplish using Views PHP. Instead I ended up just trimming the default field (under Rewrite results). Not exactly the desired effect, but it does not return that error and since we're working against a deadline, it will have to do for now. I'll keep following this issue thread though, should a solution be proposed.

@jacquelynfisher, can you post the offending lines?

I was having the same issue. Adding the isset only partially worked. For whatever reason even though it wasn't set it went through once so I had to add a second trap.

If (isset($data->field_field_event_tags[0]['rendered']['#markup'])) { //I ADDED THIS LINE FIRST
$tagcnt = count($data->field_field_event_tags);

for($i = 0; $i <= $tagcnt; $i++) {

If (isset($data->field_field_event_tags[$i]['rendered']['#markup'])) { //THEN ADDED THIS LINE
$stag = $data->field_field_event_tags[$i]['rendered']['#markup'];
}
}

Adding the isset before each of the call to the markup fixed my issue, not exactly sure why it blew through the first isset though.

I ran into this as well. I have fields with data that are giving me an error message, even though the data is being pulled. (How is that possible?) I have to abandon views altogether for this project because of the bug.

Using the "isset" function to check if a field is not set was enough to get me past this bug. You may have to do it for each field being rendered via PHP.

For me, the fields were set, with data, but I still received an error. (The data was still included in the reslults, but the error message made the page useless.)

I have the results correctly displayed but always this error... How can we get rid of it?

looks more infomation is needed to reproduce this inssue, then we can fix it.

May you advise the way to product this problem?

My fault: made a mistake in my code that led me to this thread; everything works fine now! Sorry

echo 'hi';
$query = db_query("select fa.field_currency_amount as amount from {field_data_field_currency} as fa inner join
 {field_data_field_date} as d on fa.entity_id = d.entity_id where fa.bundle=:bundle 
 and d.field_date_value = :date",array(':bundle' => 'add_income', ':date' => $data->field_field_date['0']['raw']['value']));

 foreach($query as $value){
	$final = $value->amount + $final;
} 
echo '$'.$final;

when i write this cod in global php filed then error will display like this.

Notice : Undefined index: 0 in __lambda_func() (line 5 of /var/www/html/java/drupal_fb/sites/all/modules/views_php/plugins/views/views_php_handler_field.inc(202) : runtime-created function)

how can i solve this error ???

Please reopen if this is still an issue with steps to reproduce.
