The Query Variable<\/strong> is a feature of the filter creation window that allows you to set the filter more precisely. This tutorial will reveal how to use the JetSmartFilters <\/em>Query Variable<\/strong> and the post relations that can be created using the JetEngine <\/em>plugin.\u00a0<\/p>\n\n\n\n

So, let\u2019s look through the Query Variable <\/strong>customization process while creating a \u201cCheckboxes list\u201d filter.<\/p>\n\n\n\n

Create a Relation<\/strong><\/h2>\n\n\n\n
\n

Let\u2019s assume you have created the relation between the \u201cServices\u201d and \u201cDoctors\u201d Custom Post Types<\/strong><\/a>.<\/p>\n\n\n\n

\"relation<\/a><\/div>\n\n\n\n

To assign children to parents, open the list of the parent posts (in our case, \u201cServices\u201d).<\/p>\n\n\n\n

Go to one of the posts and find the Children \u2026<\/strong> section. Press the \u201cConnect \u2026<\/strong>\u201d button to attach a related post.<\/p>\n\n\n\n

\"connect<\/a><\/div>\n\n\n\n

In the pop-up, press the SELECT \u2026 <\/strong>field to activate the search bar with all the available child posts. Select one and press the \u201cConnect \u2026<\/strong>\u201d button to save the item.<\/p>\n\n\n\n

\"connect<\/a><\/div>\n\n\n\n

As soon as you attach the needed items, click the \u201cUpdate<\/strong>\u201d button at the top of the page and repeat the procedure for the rest of the parent posts.<\/p>\n<\/div><\/div>\n\n\n\n

Create a Listing for Child Posts<\/strong><\/h2>\n\n\n\n
\n

Let\u2019s create a Listing template<\/strong><\/a> for child posts by moving to the WordPress Dashboard > JetEngine > Listings<\/em> <\/strong>tab <\/strong>and clicking the \u201cAdd New<\/strong>\u201d button.\u00a0<\/p>\n\n\n\n

In the Setup Listing Item <\/strong>pop-up, complete the pre-customization fields: pick the needed Listing source<\/strong>, complete the following field (in our case, From post type<\/strong>), set the Listing item name<\/strong>, <\/strong>and pick the preferred Listing view<\/strong>.<\/p>\n\n\n\n

Then, press the \u201cCreate Listing Item<\/strong>\u201d button.<\/p>\n\n\n\n

\"setup<\/a><\/div>\n\n\n\n

In the selected builder, add desired widgets\/blocks\/elements to display the dynamic content.<\/p>\n\n\n\n

For instance, a Dynamic Image<\/strong> widget<\/a> to pull out a thumbnail, a Dynamic Field<\/strong> widget<\/a> to pull out a title, etc.\u00a0<\/p>\n\n\n\n

Once done, click the \u201cUpdate<\/strong>\u201d button.<\/p>\n\n\n\n

\"listing<\/a><\/div>\n<\/div><\/div>\n\n\n\n

Create a Filter<\/strong><\/h2>\n\n\n\n
\n

Go to WordPress Dashboard > Smart Filters > Add New<\/em><\/strong> to build a filter.<\/p>\n\n\n\n

Complete the Filter Name <\/strong>field and choose the desired option as the Filter Type<\/strong>.<\/p>\n\n\n

<\/svg><\/div>
Things to know<\/div>

The Query Variable<\/strong> feature is not available for the \u201cAlphabet,\u201d \u201cUser Geolocation,\u201d and \u201cLocation & Distance\u201d Filter Types<\/strong>.<\/p><\/div><\/div>\n\n\n\n

\"checkboxes<\/a><\/div>\n\n\n\n

For instance, we select a \u201cCheckbox list\u201d Filter type<\/strong> and set its Data Source <\/strong>to \u201cPosts.\u201d\u00a0<\/p>\n\n\n\n

The Post Type<\/strong> dropdown contains the list of available post types. We choose the parent post type from the relation, in our case, \u201cServices.\u201d<\/p>\n\n\n

<\/svg><\/div>
Things to know<\/div>

Pick the same option if you want the filter to include the parent options that will filter the child items. If, in contrast, you have created a listing template for parent post type and want the filter to include the children options that will filter the parent items, pick the child post type in the Post Type<\/strong> field.<\/p><\/div><\/div>\n\n\n\n

\"query<\/a><\/div>\n\n\n\n

Click the \u201cDynamic tags<\/strong>\u201d button next to the Query Variable <\/strong>field to open the list of the options that can be pulled dynamically to this field.<\/p>\n\n\n\n

\"query<\/a><\/div>\n\n\n\n

Among the options, pick the \u201cJetEngine: filters children items list by parent IDs\u201d option and define the Relation <\/strong>you are working with.<\/p>\n\n\n

<\/svg><\/div>
Things to know<\/div>

If you build a filter with children options that should be filtering the parent items, select the \u201cJetEngine: filters parents items list by children IDs\u201d option correspondingly.<\/p><\/div><\/div>\n\n\n\n

Then, complete Filter Labels <\/strong>if desired and press the \u201cUpdate<\/strong>\u201d button to save the filter.<\/p>\n\n\n\n

\"related<\/a><\/div>\n\n\n\n

You can also activate the Use Default Filter Value <\/strong>toggle, if desired, to set the Default Filter Value<\/strong>.<\/p>\n\n\n\n

For instance, we want two options to be preselected in the filter by default. To do so, we put the ID of the corresponding posts in the following format: \u201c3113,3114\u201d (the IDs should be separated by a comma).<\/p>\n\n\n\n

\"use<\/a><\/div>\n<\/div><\/div>\n\n\n\n

Add Filter to Page<\/strong><\/h2>\n\n\n\n
\n

Open the page where you want your filter and Listing <\/strong>to appear. <\/p>\n\n\n\n

Find the needed filter block\/widget\/element, and drag and drop it to the page. In the Select filter<\/strong> field, choose the filter you have just created.<\/p>\n\n\n\n

Navigate to the This filter for <\/strong>dropdown and select the \u201cJetEngine\u201d option.<\/p>\n\n\n\n

\"checkboxes<\/a><\/div>\n\n\n\n

After you customize the filter, drag and drop the Listing Grid<\/strong><\/a> block\/widget\/element on the page.\u00a0<\/p>\n\n\n\n

In the Listing <\/strong>dropdown, select the previously built listing item. In our case, it\u2019s the listing with the children items.<\/p>\n\n\n

<\/svg><\/div>
Things to know<\/div>

The filter can be used with different providers<\/a> included in the This filter for field of the filter.<\/p><\/div><\/div>\n\n\n\n

\"listing<\/a><\/div>\n\n\n\n

Complete the page customization as desired and click the \u201cPublish\/Update<\/strong>\u201d button.<\/p>\n\n\n\n

Open this page on the front end to check the result. Now, you can observe that the default values set during the filter creation process are selected.<\/p>\n\n\n\n

\"preset<\/a><\/div>\n\n\n\n

You can reselect the desired option(s) in the filter to see if it works.<\/p>\n\n\n\n

\"checked<\/a><\/div>\n<\/div><\/div>\n\n\n\n

That\u2019s it; now you know how to set the Query Variable <\/strong>field while the JetSmartFilters <\/em>filter by related items creation on your WordPress website.<\/p>\n","protected":false},"excerpt":{"rendered":"
