    Checking for non-required attributes

    I've seen a few post on how to count the attributes of a product, such as:

    Code:
    <mvt:assign name="g.attribute_count" value="miva_array_elements( l.settings:attributes )" />
    <mvt:if expr="g.attribute_count EQ 0">    
    There are no attributes
    <mvt:else>    
    There are attributes
    </mvt:if>
    Is there a way to count only non-required attributes? In fact all I really need to know is if there is at least 1 non-required attribute.

    If I changed the above code to: value="miva_array_elements( l.settings:attributes:required )" I think it would still return a count since this variable exist for all attributes and is true or false.

    don't know of the top of my head if that function can take an expression or if l.settings:attribute:required is the correct value, but try miva_array_elements(l.settings:attribute:required EQ 1)

      The expression l.settings:attributes:required will not return any value; that's not how Miva Script works. l.settings:attributes is an array; it has numbered elements, each of which holds the data for one attribute. Miva Script doesn't have a way to directly read or count the :required values of all the array elements. To count the number of required or non-required attributes, or to check whether there are any, you'll need to write a small mvt:foreach loop that goes through all the attributes, and checks the :required element of each one.

        This may be a dead thread but I thought this would be helpful to the original poster or anyone else who stumbles upon the thread.

        I needed something similar as the original poster but based on if required attributes existed so I will include examples for both.

        Both the code examples are based on a variable assigned and counted with a small foreach loop as Kent suggested.

        Code to check if Required Attributes exist

        Code:
        <mvt:assign name="g.reqpos" value="1" />
        <mvt:foreach iterator="attribute" array="attributes">
                <mvt:if expr="l.settings:attribute:required">
                        <mvt:assign name="g.reqpos" value="g.reqpos + 1 " />
                        <mvt:foreachstop />
                </mvt:if>
        </mvt:foreach>
        <mvt:if expr="g.reqpos GT 1">
                CONTENT IF REQUIRED ATTRIBUTE EXISTS
        <mvt:else>
                other content (this content and the <mvt:else> are not required if only showing content based on required attributes existing)
        </mvt:if>
        Code to check if Non-Required Attributes exist

        Code:
        <mvt:assign name="g.nonreqpos" value="1" />
        <mvt:foreach iterator="attribute" array="attributes">
                <mvt:if expr="l.settings:attribute:required">
                        <mvt:comment> ========== Important to keep this blank and free of code or text ========== </mvt:comment>
                <mvt:else>
                        <mvt:assign name="g.nonreqpos" value="g.nonreqpos + 1 " />
                        <mvt:foreachstop />
                </mvt:if>
        </mvt:foreach>
        <mvt:if expr="g.nonreqpos GT 1">
                CONTENT IF NON-REQUIRED ATTRIBUTE EXISTS
        <mvt:else>
                other content (this content and the <mvt:else> are not required if only showing content based on non-required attributes existing)
        </mvt:if>
        Hope this is helpful.

          It would be great if there was a way to incorporate a while loop that could exit the loop after finding the first required or non-required attribute.

          Not sure if that is possible but we have products with a lot of attributes and it may be more efficient that way.

            The template language includes <mvt:foreachstop>, which can be used to break out of a loop.

              Ah ha. Did not know that one existed.

              Edited the code in the post.

              Thanks Kent!
