How to use php (wordpress) functions in AngularJS partials files?

Question

I am using angularjs to load a list of my wordpress posts, however I can not get any of my php functions to work with my partials file.

I've tried using something such as search.php instead of search.html but when doing so I get errors such as fatal error get_post_meta is undefined.

Now I know we are not suppose to mix client side with server side, and I can possibly use some kind of service to parse my php, but I have no idea how to go about it. I need my search.php to render my php tags so I can display custom fields, and use several php functions I have there.

Whats the best way of doing this?

On my page template (.php) I have --

<div id="page" ng-app="app">
        <header>
            <h1>
                <a href="<?php echo home_url(); ?>">Search</a>
            </h1>
        </header>
  <?php if (have_posts()) : ?>
<?php while (have_posts()) : the_post(); ?>

   <div ng-Cloak ng-controller="MyController" class="my-controller">
<div ng-view></div>     
</div>
  <?php endwhile; ?>
 <?php endif; ?>
<?php rewind_posts(); ?>
<div ng-controller="OtherController" class="other-controller">
          <div class="text-center">
          <dir-pagination-controls boundary-links="true" on-page-change="pageChangeHandler(newPageNumber)" template-url="/partials/dirPagination.tpl.html"></dir-pagination-controls>
          </div>
        </div>
        <footer>
            &copy; <?php echo date( 'Y' ); ?>
        </footer>
    </div>

And on my php file I want to be called into view has functions such as --

<?php 
$pcomp1b = get_post_meta(get_the_ID(), 'pa_meta_comp1b', true); 
$pcomp1c = get_post_meta(get_the_ID(), 'pa_meta_comp1c', true);
$pcomp1d = get_post_meta(get_the_ID(), 'pa_meta_comp1d', true); ?>

Math --

if( is_numeric( $price1 ) ) {
    $a1 = $price1;
}
$b1 = $pcomp1d;
$sqft1 = str_replace( ',', '', $b1 );

if( is_numeric( $sqft1 ) ) {
    $b1 = $sqft1;
}

$a2 = $pcomp2f;
$price2 = str_replace( ',', '', $a2 );

if( is_numeric( $price2 ) ) {
    $a2 = $price2;
}
$b2 = $pcomp2d;
$sqft2 = str_replace( ',', '', $b2 );

if( is_numeric( $sqft2 ) ) {
    $b2 = $sqft2;
}

$a3 = $pcomp3f;
$price3 = str_replace( ',', '', $a3 );

if( is_numeric( $price3 ) ) {
    $a3 = $price3;
}
$b3 = $pcomp3d;
$sqft3 = str_replace( ',', '', $b3 );

if( is_numeric( $sqft3 ) ) {
    $b3 = $sqft3;
}
$ppsqft1 = ROUND($price1 / $sqft1);
$ppsqft2 = ROUND($price2 / $sqft2);
$ppsqft3 = ROUND($price3 / $sqft3);

$ppsav = ROUND((($ppsqft1 + $ppsqft2 + $ppsqft3)/3));

$b4 = $property_area;
$parea = str_replace( ',', '', $b4 );

if( is_numeric( $parea ) ) {
    $b4 = $parea;
}
$ehvp = $ppsav * $parea;
$homevalue = number_format($ehvp, 0, '.', ',');
echo '$' . $homevalue; ?>

And functions --

<?php if (class_exists('MRP_Multi_Rating_API')){ MRP_Multi_Rating_API::display_rating_result(array('rating_item_ids' => 2, 'show_count' => false, 'result_type' => 'value_rt', 'no_rating_results_text' => 'N/A'));} ?>

My app script --

var app = angular.module('app', ['ngRoute', 'ngSanitize', 'angularUtils.directives.dirPagination'])

function MyController($scope) {


$scope.currentPage = 1;

$scope.pageSize = 2;

$scope.posts = [];


$scope.pageChangeHandler = function(num) {

console.log('search page changed to ' + num);
  };
}



function OtherController($scope) {

$scope.pageChangeHandler = function(num) {

console.log('going to page ' + num);
  };
}

app.config(function(paginationTemplateProvider) {
    paginationTemplateProvider.setPath('/partials/dirPagination.tpl.html');
});

app.config(function($routeProvider, $locationProvider) {
    $locationProvider.html5Mode(true);

    $routeProvider
    .when('/search-results', {
        templateUrl: myLocalized.partials + 'main.html',
        controller: 'Main'
    })
    .when('/:ID', {
        templateUrl: myLocalized.partials + 'content.html',
        controller: 'Content'
    });
})
app.controller('Main', function($scope, $http, $routeParams) {
    $http.get('wp-json/posts?type=property').success(function(res){
        $scope.posts = res;
    });
})
app.controller('Content', function($scope, $http, $routeParams) {
    $http.get('wp-json/posts?type=property/?filter["posts_per_page"]=25&filter["orderby"]=date&filter["order"]=desc/' + $routeParams.ID).success(function(res){
        $scope.post = res;
    });
});


app.controller('MyController', MyController);
app.controller('OtherController', OtherController);

So how can I get this to work with ng-view and my partials templates?

UPDATE

I do use wordpress api and I am aware of {{tag}} ... I need specific things done with php though. Is there a way to preprocess it into the partial files?

Answer 1

If you want to include wordpress native functions in external php file (not default template file), you can load the wordpress default functions by loading wp-blog-header.php or wp-load.php into that file

like adding, require_once("/path/to/wordpress/wp-load.php"); at the very beginning.

You can refer the code below for $http request retrieving json data,

var app = angular.module('recentPost', []);
app.controller('PostController',  ['$scope', '$http', function($scope, $http) {
    $http.get('your_json_url')
    .then(function(response) {
        console.log( response );    
        /*if ( response.data !== '-1' ) {
            $scope.lists= JSON.parse(response.data.data_received);
        } else {
            $scope.lists= response;
        }*/
    }
}]);

Additionally, I don't see the point of using AngularJS directly into wordpress, there's already jQuery+Ajax you can use, there's no point loading additional library
