Do I need fall protection training and certification in [City], ON?
According to the Government of Ontario and OHSA Regulation 213/91: Construction Projects, all employees need fall protection training and certification if they work on sites involving the use of:
[_padding] => Array
(
[unit] => px
[top] => 90
[right] => 90
[bottom] => 90
[left] => 90
[isLinked] => 1
)
)
[elements] => Array
(
)
[widgetType] => text-editor
)
)
[isInner] =>
)
)
[isInner] =>
)
)
Actually this is an elemntor array, which has all the page data stored in and I want to replace [City] with a value. Is this Possible?
