callback function for an ajax form in wordpress

Question

i make a wordpress advance search with jquery. when user click on search button, by using jquery i get all my search parameters and send with $.post() function to admin-ajax.php ... i create a function in functions.php file and receive all search values and write wp_query to fetch wp posts.

$args = array(
'category_name' => '3d');$query = new WP_Query($args);

if ($query->have_posts()) {
while ($query->have_posts()) {
    $query->the_post();
    echo '<a href="'. the_permalink() .'">test</a>';
}
wp_reset_postdata();

}

in the above code when i printed a tag, output is something like this:

http://localhost/site/%d8%af%d8%a7%d9%86%d9%84%d9%88%d8%af-%d9%81%db%8c%d9%84%d9%85-zootopia/test0

problem 1: test is a link but doesn't have any href! the href of link printed outside of link like a string! problem 2: "0" character automatically printed after all output values even empty echo in php will print "0" character! please help me, thanks...

You need to replace code with this. Because you are using the_permalink() instead of get_the_permalink() when inside echo.

https://developer.wordpress.org/reference/functions/get_the_permalink/ https://developer.wordpress.org/reference/functions/the_permalink/

$args = array('category_name' => '3d');
$query = new WP_Query($args);

if ($query->have_posts()) {
    while ($query->have_posts()) {
        $query->the_post();
        echo '<a href="'. get_the_permalink() .'">test</a>';
    }
    wp_reset_postdata();
}
