How to display a certain category from a form

HI,
You can try the script below ( added to the functions.php file of the theme ). Then replace the values of $taxonomy and $term_slug based on your needs.

function gmw_filter_form_by_cateogry_page( $tax_args, $gmw ) {

        // enter the taxonomy slug for example 'directory_categories'
        $taxonomy = 'directory_categories;

        // enter the term slug that you'd like to display. For example 'wine_and_dining'
         $term_slug = 'wine_and_dining';

	// create the filter based on taxonomy and terms ID
	$tax_args = array(
		array(
			'taxonomy' => $taxonomy,
			'field'          => 'slug',
			'terms'       => $term_slug,
		)
	);

	return $tax_args;
}
add_filter(  'gmw_pt_tax_query', 'gmw_filter_form_by_cateogry_page', 90, 2 );

filter_form_by_cateogry & gmw_filter_form_by_cateogry_page

is this meant to be category instead of cateogry?

Also, what is this line doing in the code?
add_filter( 'gmw_pt_tax_query', 'gmw_filter_form_by_cateogry_page', 90, 2 );

Will this apply to all of the forms or just [gmw form=”1″] and I can just put that code in the page?

Thank you for your help.

Any updates on this issue?

Thank you!

HI,

Yes, it is a typo and you can fix it. But it should have still worked this way.

Also, what is this line doing in the code?
add_filter( ‘gmw_pt_tax_query’, ‘gmw_filter_form_by_cateogry_page’, 90, 2 );

gmw_pt_tax_query is a filter that executes the function gmw_filter_form_by_cateogry_page(). The function should change the value of the taxonomy argument.

Will this apply to all of the forms or just [gmw form=”1″]

The above will apply to all forms. You can limit it to a specific form, for example form with ID 1, using the below:

function gmw_filter_form_by_cateogry_page( $tax_args, $gmw ) {

        if ( $gmw['ID'] != 1 ) {
            return $tax_args;
        }

        // enter the taxonomy slug for example 'directory_categories'
        $taxonomy = 'directory_categories;

        // enter the term slug that you'd like to display. For example 'wine_and_dining'
         $term_slug = 'wine_and_dining';

	// create the filter based on taxonomy and terms ID
	$tax_args = array(
		array(
			'taxonomy' => $taxonomy,
			'field'          => 'slug',
			'terms'       => $term_slug,
		)
	);

	return $tax_args;
}
add_filter(  'gmw_pt_tax_query', 'gmw_filter_form_by_cateogry_page', 90, 2 );

and I can just put that code in the page?

You need to add the code to the functions.php file of your theme or child theme and change the value of $taxonomy and $term_slug in the function based on your needs.
