All language subtitles for 003 Passing and Rendering Data in Templates_en

Let's see how we can pass some additional data to the blade template and then how do you output this

data inside the template for the purpose of this lecture?

Let's define our simple poster that will hold the data we want to pass onto the template.

So this code chunk is available as a download under this lecture.

So download it and paste it inside the root.

It's on the right holding a race.

And unless Iterate also has keys, which we will try to match against the ID root parameter.

Now, let's render the new template we are yet to create

and pass the array containing blog post data for a given ID.

Then let's create the proper template for displaying a blog post.

Again, let's follow the route naming convention and create our posts folder and then show Blade B inside

it.

For the most part, we can copy paste from previously created templates.

The difference here is the section's content.

If you would, take a look at how we have passed the data, every Iraqi defined in the controller becomes

Arpège variable available in the template.

Now, let me coat and of course, you can coat along how we would outpoured past the data and then we

will go through it step by step.

So first, let's have a specific title for this page.

Then I'll add an age one element for a blog, post title and paragraph for the content.

Now, let's use this special syntax first to output the title.

Secondly, to output the content.

Now, the new thing here is the double bass syntax, sometimes also called the mustache.

If you take a closer look, you can see a mustache there between this bracers.

You can put any data or variables that are available in the template.

Since we are passing on the rate, we can access its elements by key using bracket syntax.

It's important to note that everything put through their mustache syntax is passed through HDMI special

char speech function that converts special characters to HDMI entities for security reasons.

You can influence how the data is rendered, though, there is a separate lecture about that.

So let's try it out, go to the browser and visit post one, you should get some output and let's go

visit the second blog post.

It works to also the title is Being Adjusted.

Finally, if you will try out what happens if you provide an invalid ID, you get an error page are

pretty useful error page.

So be sure to look around at what info is available here.

But I don't want to let you go with a code that is unfinished, so let's go back to where you've been

and you can use this handy board E Floraville helper function.

What it does is it can generate an error when a condition is met.

In our case, it's the missing array key for the given I.D. route parameter.

So let's implement it.

So if it's not set posts array with our specific ID, we could return for or for error, which means

not found.

Save the changes, remember this helper function as it is often coming handy.

So let's finally try it out.

Now, let's refresh this page with an invalid I.D. and you can see we are directed to a nice 404 not

found.
