Hoping There is an easy way to do this/I am doing something horridly wrong: I'm trying to simply display a list of post titles. When a user clicks on the title it will display that said title's content into a previously empty div on the same page with ajax.

however it won't work correctly if I switch around the permalinks etc or have a post that's url is a few directories deeps (ie: site.com/dir1/dir2/dir3/page, or site.com/dir1/page). It will ONLY work if I have site.com?p=23

BECAUSE of this relative url in my ajax request:


//whenever a title is clicked on: run this request


    $portfolioPostId = $(this).data('postid');  

        type: 'GET',
        url: '../wp-admin/admin-ajax.php',  //WON'T LOAD on any url that ISN'T like this format: site.com/?p=123
        data: {
            action: 'my_post',
            postid: $portfolioPostId
        success: function(data){

            $('#well').html(' ');

        error: function(XMLHttpRequest, textStatus, errorThrown){

            console.log(errorThrown) + '\n';





So INSTEAD of having url: '/wp-admin/admin-ajax.php', how could I instead use an ABSOLUTE URL? Or is there something better that could be done?


Thanks to Rarst's answer I was able to find a way to pass the absolute URL.

On my php file where I enqueue my script, I also sent through an object called psAjax_object that contained the absolute URL to admin-ajax.php

function frontend_js(){

    wp_enqueue_script('shuffle_ajax', plugins_url( NAME . '/public/js/portfolio_grid_ajax.js'), array('jquery'), '', true );

    //creates the property for the 'psAjax_object'
    $localizedArray = array('ajax_url' => admin_url('admin-ajax.php'));

    //allows my portfolio_grid_ajax.js file to access 'psAjax_object'
    wp_localize_script('shuffle_ajax', 'psAjax_object', $localizedArray);

add_action('wp_enqueue_scripts', 'frontend_js');

and then in my js file i can access the absolute url by typing psAjax_object.ajax_url

  • You'll need to localize your script.. after you enqueue it to the frontend. Pass the admin_ajax() url in a javascript variable.. then access it in your ajax request.

The normal practice is to generate URL on PHP side ( admin_url() ) and provide it to your script via localization functionality ( wp_localize_script() ). It is documented in Codex under Ajax on the Viewer-Facing Side.
