A PHP Error was encountered Severity: Notice Message: Undefined index:

#1
Hi I have a site which was previously built by someone we no longer deal with and whilst I have been able to sort many issues out one keeps getting my all twisted,

I have an area on my dashboard which allows me to add a file to upload a pdf

and when on the front end it gives me a clickable link.

I now need to add an extra PDF in the same format, so I have copied the code in the admin modules added it below the other PDF and changes the details as required  and have been able to make it appear in the dashboard it all works adds the file to the DB and puts it in the correct folder.

then I copied the relevant code for the front end change the details and the link appears but i get this error message.



A PHP Error was encountered

                if(!empty($accessories[0]['accessories_fitting_pdf_file']))

The error means the variable $accessories[0] does not have an index called "acccesories_fitting_pdf_file". In other words the array item $accessories[0]['accessories_fitting_pdf_file'] does not exist.

You should look in the controller that loads the view file for the array key 'accessories', i.e. $data['accessories']. (It might not be named $data. It could have any valid variable name. That variable will be passed to the $this->load->view(...); method.)

Based on the view's code there should be code in the controller that sets the value of $data['accessories'] to an array. One of the keys of that array should be named 'accessories_fitting_pdf_file'. Make sure some such code exists and that actual values are properly assigned.

Hi Dave,

thank you for your response, I've search through the controller file and the information in my opinion is correct I can't see where I have missed changing a name, I simply coppied it from the relevant code and pasted it back in and then changed from accessories_pdf_file to accessories_fitting_pdf_file,
I've been staring at the same bits of code for a day and a half now,

This is the code for the controller

and this is the page http://www.ohm.co.uk/accessories/lwb-pt
were the fault is occurring.

I appreciate any help thank you.
