Render Functions & JSX Basics. Vue recommends using templates to build your HTML in the vast majority of cases.

In this tutorial, we will make use of VueJS and PHP to build a really cool keyword density tool. On the Vue side, we’ll make use of components, templates, and root elements, and more. We will use PHP to generate the form we need, as well as to handle form processing, in addition to making use of the substrcount function to provide the data we need.
You might also like how to as well. Let’s see how we can do this, it should be fun.Declare The Vue ComponentThe first step that we will take is to declare a component for our application. In this instance, we are creating a keywordcounter component as shown by the first argument passed to the.component method.
We pass an object as the second parameter to this method. It has properties of,. The template is a string which serves as the actual markup for the. In this example, it begins with a hashtag, which means that Vue will treat this string as a querySelector for which that innerHTML will be used as the template string. Our props property is an object, which in this case contains to properties, data and columns.
The values of these properties are arrays, and we will fill them dynamically a little later on. The data property holds a function, or rather references a function. There is a bit of magic happening here, as Vue actually turns any properties into getters and setters which is what gives the framework it’s reactive nature. Finally, we have the methods property, which is an object that contains methods to be used in the Vue instance. It is a means of keeping all of your functionality neat and tidy. Methods in the methods property have their set to the Vue instance.
Present a form to enter a haystack and keyword(s) to searchIn this step we will use a simple combination of HTML and PHP to present a form for which we can collect some data. First off, we have a form element with the action set to substrcount.php and the method is post. What this means is that we will use the post http method to submit any data we collect to the PHP file named substrcount.php. In our case, this is literally a single page application, so all snippets on this page can be assembled in order to create your own working example. Inside of the form tag, we have a textarea which will accept the data to be known as haystack, and a text input which will collect a comma separated list of keywords that we will analyze in the haystack data.

Our inputs make use of the isset PHP function in order to repopulate the inputs on each successive testing of data. This way, you wouldn’t have to re enter all of the information into the form in order to search on say a different set of keywords. Finally we have just a simple button which allows us to submit the form.
