Matrix Total Rows Column Search Conditional

Question

So I have this conditional that works properly for entries with matrix rows:

{if {tech_documents:total_rows search:doc_thumb="IS_EMPTY"} > 0}
    ...
{if:else}
    ...
{/if}

However, entries that have no rows for this matrix field throw a template error:

Error

You have an invalid conditional in your template. Please review your conditionals for an unclosed string, invalid operators, a missing }, or a missing {/if}.

Parser State: Invalid Condition: Not enough operands for operator ” > “.

Running: EE 2.9, Matrix 2.6, Assets 2.4

Answer 1

EE simply removes any tags corresponding to custom fields that have no data. So by the time EE is ready to parse the outer {if} conditional, it will look like this:

{if  > 0}

Try wrapping the field tag in quotes:

{if '{tech_documents:total_rows search:doc_thumb="IS_EMPTY"}' > 0}

Answer 2

try with below code:

{if tech_documents:total_rows > 0 && search:doc_thumb="IS_EMPTY"}
    ...
{if:else}
    ...
{/if}
