Hello,

NOTE: before you can use a field you should make sure that it's display is created , by editting your template layout and adding the field in "RenderOnly" position,

then you can use it, as mention above,
NOTE the default performance setting in
- Componet params / Options / Create Field display

is to always create fields in Item view

so the above mentioned code will work in item view without adding to "Render Only" position, but not in category view

prefer to set parameter: Create Field display to Only when needed and add your field to Render only position for item layout too

Regards

I created my own item.xml and I didn't add a "renderonly" group. How would I activate that in my template? I made my own template and I was not aware of this.

Hello

1. just see the image here (edit category.xml and item.xml):

2. clear cache
3. Add you fields in the renderonly position and then use them inside the PHP code item.php

Hello

please look at your code carefully,
and if you use print_r on various variables, you will see what is available:

Most notably do:

Code:

echo "<pre>" . print_r($this->item, true) . "</pre>";

on the ITEM variable to see what is available

it is cumbersome for us to look at long listings of code, particularly since we ... can not run it locally

Also we said above that this wrong, but you still have it in your code:
$this->fields->display

does not exist !

instead use [c:del0dl2u]$this->item->fields['web']->display[/c:del0dl2u] for item view
and [c:del0dl2u]$this->items[$i]->fields['web']->display[/c:del0dl2u] for category view
