component load based on category value change in vuejs

To load a different component based on a change in category value in Vue.js, you can use the computed property to return the appropriate component based on the selected category value.

Here's an example code snippet:

<template> <div> <select v-model="selectedCategory"> <option v-for="category in categories" :key="category" :value="category"> {{ category }} </option> </select> <component :is="currentComponent"></component> </div> </template> <script> import Component1 from './Component1.vue'; import Component2 from './Component2.vue'; import Component3 from './Component3.vue'; export default { components: { Component1, Component2, Component3, }, data() { return { selectedCategory: 'Category 1', categories: ['Category 1', 'Category 2', 'Category 3'], }; }, computed: { currentComponent() { if (this.selectedCategory === 'Category 1') { return 'component1'; } else if (this.selectedCategory === 'Category 2') { return 'component2'; } else if (this.selectedCategory === 'Category 3') { return 'component3'; } else { return 'component1'; } }, }, }; </script>

In this example, we have a select element that allows the user to choose a category. We use v-for to loop through the categories array and display each category as an option in the select element.

We use the component element to dynamically display the current component based on the selected category value. We use the :is attribute to bind the component to the currentComponent computed property.

We import the components (Component1, Component2, and Component3) at the top of our Vue component and register them as local components using the components option.

We use the computed property to return the appropriate component based on the selected category value. We use an if-else statement to check the value of the selectedCategory property and return the appropriate component name as a string.

Note that you can also use the watch option to monitor changes to the selectedCategory property and perform some actions based on the new value. However, using a computed property is generally a cleaner and more efficient way to dynamically display components based on a data property.

4.config .env file.

5. then run

composer require laravel/ui

php artisan ui vue --auth

php artisan migrate

6. now project is ready.

7. install laravel collective.

composer require laravelcollective/html

The 27 Most Useful PHP Array Functions.

Now, we know What is Array in PHP? and how it work in PHP. After creating an array we need to count values in array, sort arrays by their contents, convert them between strings and arrays, find unique values, search within arrays, compare arrays to other arrays and more.

By using array functions we can easily access and manipulate an array. In following I am going to describe array function with example.

Note that the following array function is mostly used in PHP array to access and manipulate the arrays.

is_array():

This function is used to find whether a variable is an array or not.

Syntax:

is_array($variable_name);

Example 1:

<?php

$array=array('x','y','z');

if (is_array($array)){

echo 'Yes! It is an array.';

}else{

echo 'No! It is not an array.';

}

?>

Output of the above program:

Yes! It is an array.

Example 2:

<?php

$mark = [

'id' => 1027,

'name' => 'John Abhram',

'class' => 'Class ten',

[ 'gender' => 'male',

[

'bangla' => '100',

'english' => '95',

'mathematics' => '85'

],

'country' => 'bangladesh'

]

];

$array1 = is_array($mark);

$array2 = is_array($mark['roll']);

$array3 = is_array($mark[0]);

echo $array1 ? 'The $mark variable is an array<br>' : 'The $mark variable is not an array<br>';

echo $array2 ? 'The "id" key of the $mark variable is an array<br>' : 'The "id" key of the $mark variable is not an array<br>';

echo $array3 ? 'The 0 index of the $mark variable is an array<br>' : 'The 0 index of the $mark variable is not an array<br>';

?>

Output of the above program:

The $mark variable is an array<br>

The "id" key of the $mark variable is not an array<br>

The 0 index of the $mark variable is an array<br>

in_array():

This function searches in an array for a specific value. It returns TRUE if this specific value is found in the array, or FALSE otherwise.

Syntax:

in_array($value, $array);

Example :

<?php

$subjects = array("English", "Mathematics", "Biology");

if (in_array("Mathematics", $subjects)) {

echo "Subject Mathematics is exist";

}

if (in_array("Biology", $subjects)) {

echo "Subject mathematics is exist";

}

?>

Output of the above program:

Subject Mathematics is exist

array_unique():

This function helps to remove duplicate values from an array. The first appearance will be kept when two or more array values are the same and the other will be removed.

Syntax:

array_unique($array);

Example :

<?php

$subjects = array("array1" => "Bangla", "English", "array2" => "Bangla", "English", "Mathematics");

$result = array_unique($subjects);

print_r($result);

?>

Output of the above program:

Array ( [array1] => Bangla [0] => English [2] => Mathematics )

array_search():

This function search an array for a specific value and returns the key. It returns the key if the value found and false otherwise.

Syntax:

array_search($value, $array);

Example :

<?php

$array = array("x"=>"Bangla","y"=>"Turorial","z"=>"Stars");

print_r(array_search("Turorial", $array));

?>

Output of the above program:

y

array_reverse():

This array function return an array in reverse order with this array elements.

Array Counting Functions:

There are some array functions those are related to counting values or dealing with numbers. We can count the number of values in an array and also return the maximum or minimum value and others useful operations.

count():

Using this function we can know how many values are presented in a array.

Example 1:

<?php
$a=array("Television","Radio","Radio","Television","Computer");
print_r(array_count_values($a));
?>

Output of the above program:

Array (
[Television] => 2
[Radio] => 2
[Computer] => 1
)

PHP - Sort Functions For Arrays:

sort():

Syntax:

sort($array);

Example 1:

<?php
$people = array("American", "China", "Indian");
sort($people);

$array_length = count($people);

for($i = 0; $x < $array_length; $i++) {
echo $people[$i];
echo "<br>";
}
?>

Output of the above program:

American
China
Indian
