How to load page content into a variable in wordpress

Jacob

I am developing a wordpress plugin and I am using echo to display the HTML layout into the function. Is there any way to load the external html template or page content into a variable?

This is my code to render the template.

function render_template() {
    echo '<div class="wrapper">';
    .....
    .....
    echo '</div>';
}

Yes you can load the page content into the variable by doing a small trick. You can use the output buffering to store the printing contents in a variable. Take a look to the example.

function render_template() {
    ob_start();
    // Load template
    get_template_part($slug, $name);
    $content = ob_get_contents();
    ob_end_clean();
 
    return $content;
}

This is cool. I slightly modified your codes and it works perfectly for me.

function render_template() {
    ob_start();
    // Load template
    get_template_part($slug, $name);
    $content = ob_get_contents();
    ob_end_clean();
 
    echo $content;
}
