Drupal PHP Problem

General PHP Help
#1

Dear all,

Any assistance with the following would be greatly appreciated.

We have been designing a new drupal website and the following error keeps occuring - although not consistently. It only appears to show up as and when it feels like it.

Here is a link to our dev website: www.redlionlaw.co.uk

[php]
Notice: Undefined index: sublayers in include() (line 65 of /home1/myfraudl/public_html/redlionlaw/sites/all/modules/layer_slider/layer_slider.tpl.php).
Notice: Undefined index: sublayers in include() (line 65 of /home1/myfraudl/public_html/redlionlaw/sites/all/modules/layer_slider/layer_slider.tpl.php).
Notice: Undefined index: sublayers in include() (line 65 of /home1/myfraudl/public_html/redlionlaw/sites/all/modules/layer_slider/layer_slider.tpl.php).

change this line:
[php]if(is_array($layer[‘sublayers’])) {[/php]
to
[php]if(isset($layer[‘sublayers’]) && is_array($layer[‘sublayers’])) {[/php]

Red :wink:

Edit:
Just to be clear, that doesn’t actually fix the cause, but will stop the errors as it will check if isset before testing if it’s an array.
Reading through your post, there is way too many variables and not enough code for me to determine why it is happening.

Thank you for your reply. There doesn’t appear to be a real fault as everything is working perfectly - so just want the error to cease to display.

However, the solution you provided hasnt seemed to have worked :frowning: This error still displays:
