    Hello Reader's! if you are new to wordpress development and need to add more custom fields in category, Then you can learn it from the code below:-

    Step:1- Open the file functinon.php and add the following code in it.

    add_action( 'category_edit_form_fields', 'dot_img_custom_fields', 10, 2 );
    
    function dot_img_custom_fields($tag)
    {   
        $img_id = $tag->term_id; // Get the ID of the term you're editing
        $img_url = get_option( "taxonomy_term_$img_id" ); // Do the check
        ?>
        <tr class="form-field">
            <th scope="row" valign="top">
                <label for="extra_information"><?php _e('Insert Featured Image Link'); ?></label>
            </th>
            <td >
                <input type="text" name="img_url[get_img]" size="7" style="width:95%;" value="<?php echo $img_url['get_img'] ? $img_url['get_img'] : ''; ?>" placeholder="Link" />
            </td>
        </tr>
        <?php
    }
    
    // Save the changes made on the "faq_category" taxonomy, using our callback function  
    add_action( 'edited_category', 'save_img_custom_custom_fields', 10, 2 );
    
    // A callback function to save our extra taxonomy field(s)  
    function save_img_custom_custom_fields( $term_id )
    {  
        if ( isset( $_POST['img_url'] ) )
        {  
            $img_id = $term_id;  
            $img_url = get_option( "taxonomy_term_$img_id" );  
            $img_keys = array_keys( $_POST['img_url'] );  
                foreach ( $img_keys as $img_key ){  
                if ( isset( $_POST['img_url'][$img_key] ) ){  
                    $img_url[$img_key] = $_POST['img_url'][$img_key];  
                }  
            }
    
            //save the option array  
            update_option( "taxonomy_term_$img_id", $img_url, $allowed );  
        }
    } 
    

    Now when you will see this added field in uploading the category.
