Toolkit Replacement - substring?

[mstella1]

Hi,
I am trying to display the first 3 characters of a string and was using Toolkit substring to do that. Is there a replacement for the code below?

<mvt:item name="toolkit" param="newsubstring|zoom_code|l.all_settings:category:code,1,3" />
<a href="&mvt:global:sessionurl;&Screen=ZOOMPRICE&[B][COLOR=#e74c3c]mvt:global:zoom_code[/COLOR][/B]">Pricing</a>

Thanks,
Mike

You can use the substring_var function to do that functionality:

<mvt:assign name="g.zoom_code" value="substring_var( l.settings:category:code, 1, 3 )" />
<a href="&mvt:global:sessionurl;&Screen=ZOOMPRICE&mvt:global:zoom_code;">Pricing</a>

Thank you that works!

I can use what you gave me and I have another question. Is there a way to strip a character?

A few of my categories have "_" in the category code. I can write conditionals for those but thought I would ask if there is a way to just use one line of code to strip the "_" from them.

You can use the glosub function to strip a character from a variable, something like this:

<mvt:assign name="g.strippedCategoryCode" value="glosub( l.settings:category:code, '_', '')" />
&mvt:global:strippedCategoryCode;

Perfect!

<mvt:assign name="g.price_code" value="substring_var( l.settings:subcat:code,1,4 )" />
<mvt:assign name="g.strippedSubCategoryCode" value="glosub( g.price_code, '_', '')" />
&mvt:global:strippedSubCategoryCode;
