I am using a callback_column using the information from other column using a callback_column function.

This is just an example:




public function _callback_column_total($value, $row){
        return $total;
It works fine, but in the case I add some custom styles, por example in column a with another callback:
public function _callback_column_a($value, $row){
        return "<span style='text-align:right;padding-right:30px;width:100%;display:block;'>".$value."</span>";


then, the calculation for column total does not work anymore.

I have two questions:

1. Why it happens? It is because the value of a is  "<span style='text-align:right;padding-right:30px;width:100%;display:block;'>".$value."</span>" and not the value of a?

2. Is it possible to put the custom style with other method? I tried using javascript but it does not work when I do a search in a column.

Thanks in advance for your support.

Hi mbanolas2


Yes - this is probably a cause due to the column callback on column a... What u can do is use php's strip_tags to get rid of the tags decorated around the value on column a...

Post that .. u can surely go ahead and use it as raw value and get your output as desired.


Happy GCing :)
