Combining Search and Pagination

Our search functionality is working great. 0:00 A user can type any term they want into the search bar on each page. 0:02 They will see a list of item results, which they can click for more details. 0:06 If there are no results, we let them know. 0:11 And if they submit without a search term, they will see the full catalog. 0:13 The only issue we'll see is if our search results return more than eight items. 0:18 We only show the first eight items, but 0:23 are link to the second page does not keep our search term. 0:25 We need to finish integrating our pagination with our search results. 0:29 Back in catalog.php, let's go to our pagination section. 0:33 We have a conditional that checks for category. 0:38 Let's add a new conditional to check for search. 0:41 Again, make sure we add else if for our second condition. 0:55 If we do have a search term, 1:00 then we wanna add that to our URL just like we've done with the category. 1:02 We'll add concatenation and then our search. 1:11 We want to finish off using our ampersand, 1:19 because of the way our data is coming in and the way we have filtered our data. 1:22 This should be all we need to do. 1:27 However, there are two functions that we could run on this data 1:29 just to make sure that it's formatted the way we want. 1:32 First, because this is user input, we want to make sure that we escape the output. 1:36 We'll use our HTML special cares again. 1:42 Second, we want to make sure we're passing this data in a way that the query string 1:51 can interpret properly. 1:55 The function for this is urlencode. 1:58 There's one more place where we should update this just to be sure. 2:03 The redirects for our page numbers. 2:07 Let's copy this first if all the way down to the else, 2:09 then we'll go up to our limit results. 2:14 We'll paste this first conditional in and we'll change our spacing. 2:20 The only thing that we have to change is the pagination variable. 2:27 Let's rename this $limit_results. 2:32 We can also remove the dot for concatenation, 2:36 because we're replacing the variable not adding to it. 2:39 Let's test this out in our browser. 2:43 We'll use something fairly common, like the with a space. 2:46 We can see that there are two pages. 2:53 And when you click on the second page, 2:55 you can see that our search term has been properly formatted with a plus at the end. 2:57 If we change the page number to 3, 3:03 you can see that the redirect, redirects us properly to the last page. 3:07 You've done a fantastic job so far. 3:12 You've had opportunity to pull results out of a database and 3:15 using a variety of methods. 3:18 You've learned about the importance of refactoring to help maintain and 3:20 improve code. 3:24 You've added a pagination feature and a search feature, and 3:25 our personal media library is really starting to become useful. 3:28 There are still plenty of things that we could do to improve this application. 3:33 So, why don't you give them a try? 3:38 If you'd like some suggestions, how about trying any or all of the following? 3:40 Display the title along with the thumbnails on the catalog listing pages. 3:45 Search and more than just the title, so someone could search by author or 3:50 movie star. 3:54 Add a drop-down of categories from the search form and 3:54 allow users to narrow their search. 3:58 Create advanced search features, 4:02 such as the use of wildcards within the search term. 4:04 Allow the user to choose how many items they would like to have displayed 4:08 on each page. 4:11 Don't forget to check out our community. 4:14 It's a great place to get help if you have any questions. 4:15 You might even start contributing and helping someone else on their journey. 4:19 You'll be surprised how much you benefit when you get involved. 4:23 So, have fun and keep learning. 4:27
