I'm trying to create a dropdown of matrix field data using the search form. It's outputting the matrix data, but I can't seem to figure out how to remove duplicate content. Say I'm using the data "john doe" on multiple entries -- it's showing for every entry, not just once. Is there any way to fix this? Thanks in advance.

{exp:low_search:form query="{segment_3}"}   
    <select name="search:tags:arranger">
        {exp:channel:entries channel="products" dynamic="no"}
            {tags}<option value="{arranger}">{arranger}</option>{/tags}
    <button type="submit">Search</button>

You'll need to use the Query module for this. Something like

{exp:query sql="SELECT DISTINCT col_id_X AS val FROM exp_matrix_data WHERE field_id = Y ORDER BY val"}

...where you need to replace X with the correct column ID and Y with the correct field ID.

EDIT Alternatively, you can try this query:

{exp:query sql="SELECT col_id_X AS val FROM exp_matrix_data WHERE field_id = Y AND col_id_X != '' GROUP BY col_id_X ORDER BY val"}
  • Thanks, Low! I'm still getting an error though. The column is 'arranger' and the field is 'tags'. Here is the error: Error Number: 1054 Unknown column 'arranger' in 'field list' SELECT DISTINCT arranger AS val FROM exp_matrix_data WHERE field_id = tags ORDER BY val Filename: modules/query/mod.query.php Line Number: 53 Commented Mar 4, 2015 at 21:02
  • You need the numeric IDs here. Not the short-names. So, for example, col_id_5 and field_id = 8 if those IDs are 5 and 8. Go to the Matrix' field settings. There you can see the field_id in the URL. To get to the col_id, view the page source and look for it.

  • ...or look up the IDs using the SQL Manager: browse the exp_channel_fields and exp_matrix_cols tables.

  • Got em, but still having an issue. It's showing the items 4 times. Here's the code: {exp:query sql="SELECT DISTINCT col_id_25 AS val FROM exp_matrix_data WHERE field_id = 117 ORDER BY val"} <option>{val}</option> {/exp:query} Commented Mar 4, 2015 at 21:16
  • Try the second query I just added. Also, make sure the values are indeed the same (no trailing spaces etc).
