Nicely, we have been engaged on a website that has quantity of useful resource articles, movies, books, and weblog posts. Utilizing the default WordPress search simply wasn’t chopping it. Utilizing Google Search additionally was not a viable possibility. Subsequently, we determined to create a sophisticated search form which lets person decide which space of the positioning they need to search by limiting custom post types by way of checkboxes. Customers can mix their search queries and most significantly, we made it so the checkboxes are saved together with the search question. This lets the person sees precisely what they looked for, they usually can modify the parameters. On this article, we are going to present you methods to create a sophisticated search form in WordPress using the ability of the WordPress search question and limiting the outcomes by custom post types.

Very first thing it’s good to do is open your searchform.php file or wherever your search form is saved. Then add the next fields inside the shape code:

<input type="hidden" name="post_type[]" value="articles" />
<input type="hidden" name="post_type[]" value="post" />
<input type="hidden" name="post_type[]" value="videos" />
<input type="hidden" name="post_type[]" value="books" />

Don’t overlook to exchange the worth together with your custom post types. The code above mainly limits your search outcomes to these submit sorts. Nicely, if you happen to observed we just about added all submit sorts obtainable apart from pages. Nicely, there’s a good motive for doing so which we are going to get to later. So be sure that to incorporate ALL submit sorts that you just need to seek for utilizing the primary search button. These fields are hidden, so the person doesn’t see these.

<form role="search" method="get" id="searchform" action="<?php echo home_url( '/' ); ?>">
<input type="text" name="s" id="s" <?php if(is_search()) { ?>value="<?php the_search_query(); ?>" <?php } else { ?>value="Enter keywords &hellip;" onfocus="if(this.value==this.defaultValue)this.value='';" onblur="if(this.value=='')this.value=this.defaultValue;"<?php } ?> /><br />
    
<?php $query_types = get_query_var('post_type'); ?>
    
<input type="checkbox" name="post_type[]" value="articles" <?php if (in_array('articles', $query_types)) { echo 'checked="checked"'; } ?> /><label>Articles</label>
<input type="checkbox" name="post_type[]" value="post" <?php if (in_array('post', $query_types)) { echo 'checked="checked"'; } ?> /><label>Blog</label>
<input type="checkbox" name="post_type[]" value="books" <?php if (in_array('books', $query_types)) { echo 'checked="checked"'; } ?> /><label>Books</label>
<input type="checkbox" name="post_type[]" value="videos" <?php if (in_array('videos', $query_types)) { echo 'checked="checked"'; } ?> /><label>Videos</label>
    
<input type="submit" id="searchsubmit" value="Search" />
</form>

It will add a search field above your outcomes with the search question contained in the enter field. This may even verify which submit sorts are being looked for within the question, and make the suitable checkboxes checked. Keep in mind, how we added all submit sorts within the hidden area. Nicely, we added it simply so we are able to run the in_array verify and maintain the checkboxes checked. There was no documentation on how to do that in any other case, so this was one of the best ways we discovered that does the job. Under is a preview of how the search field appears to be like:

From there, the person can merely modify the parameter as they please.

Hopefully this text helped these in want. Once we are doing the analysis, there have been bunch of incomplete articles. Discovered the reply of including the checkboxes within the WordPress help discussion board in an older thread nevertheless they have been solely speaking about hidden fields. Whereas we needed to present customers the choice to switch the search question. Props to @tammyhart for pointing us in the suitable solution to do the checked question for the variable.
