I am trying to call a php function with a button press.
This is my code so far:
echo("<button onclick=\"import_file()\"> Import </button>");
The Javascript upload.js file:
function import_file () {
jQuery.ajax({
url: my_ajax_object.ajax_url,
data: {action: 'final_save'},
type: "POST", //request type
success:function(result){
alert(result);
}
});
}
and the action in the primary php file:
function final_save(){
check_admin_referer('import-upload');
set_time_limit(0);
$this->file = $file;
$result = $this->save();
if ( is_wp_error( $result ) ){
echo $result->get_error_message();
}else{
echo "Success";
}
}
add_action('wp_ajax_final_save', 'final_save');
add_action('wp_ajax_no_priv_final_save', 'final_save');
I also enqueued the scripts in the same file:
function enqueue_script(){
$plugins_url = plugins_url();
$base_url = get_option( 'https://www.virtualmin.archives.com' );
$plugins_dir = str_replace( $base_url, ABSPATH, $plugins_url );
$plugin = $plugins_dir.'/really-simple-csv-importer/upload.js';
wp_enqueue_script('js-file', $plugin, array('jquery'), '', false);
wp_localize_script( 'js-file', 'my_ajax_object', array( 'ajax_url' => admin_url( 'admin-ajax.php' ) ) );
//Load jQuery
wp_enqueue_script('jquery');
}
and calling this function from dispatch:
function dispatch() {
$this->header();
$this->enqueue_script();
//more code
}
Dispatch being called here:
function really_simple_csv_importer() {
load_plugin_textdomain( 'really-simple-csv-importer', false, dirname( plugin_basename(__FILE__) ) . '/languages' );
$rs_csv_importer = new RS_CSV_Importer();
register_importer('csv', __('CSV', 'really-simple-csv-importer'), __('Import posts, categories, tags, custom fields from simple csv file.', 'really-simple-csv-importer'), array ($rs_csv_importer, 'dispatch'));
}
add_action( 'plugins_loaded', 'really_simple_csv_importer' );
I am getting an admin-ajax.php 400 (Bad Request) error. Any idea what am I doing wrong? This is being coded in a plugin.
CodePudding user response:
I seem to remember reading that you need to register, localize and then enqueue the script when using ajax so instead of
wp_enqueue_script('js-file', $plugin, array('jquery'), '', false);
wp_localize_script( 'js-file', 'my_ajax_object', array( 'ajax_url' => admin_url( 'admin-ajax.php' ) ) );
try
wp_register_script('js-file', $plugin, array('jquery'), '', false);
wp_localize_script( 'js-file', 'my_ajax_object', array( 'ajax_url' => admin_url( 'admin-ajax.php' ) ) );
wp_enqueue_script('js-file', $plugin, array('jquery'), '', false);
I hope this helps
Also I know this is probably not the problem, but I thought you needed to have wp_die() or die; always in the function being called ie final_save

I can see that there is typo error in your php file so just replace following line
add_action('wp_ajax_no_priv_final_save', 'final_save');
with following one
add_action('wp_ajax_nopriv_final_save', 'final_save');
Hope this help to solve error.

Besides the answers already given by @jtowell, you're gonna want to add a nonce to your localization and check the referer on the backend. As this is might be confusing the first time around I highly recommend following the steps in the documentation.
