wordpress ajax for front end got 302 Found

4 Views

I am new with this.. I have found out that my code works only when there is a admin logged user. how can I deal with it that it can also work without any user logged and a normal user logged.

this is my js script:

jQuery('#username').blur(function() {

jQuery('.username-massage').after('<div class="alert alert-danger usercheck-w" style="color:green;">Checking...</div>');
jQuery.ajax(
{
    url: ajax_url,
    type: "POST",
    dataType: "json",
    data: {
        action: 'checkUsernameExistentVal',
        username: jQuery(this).val(),
    },
    async: false,
    success: function (data)
    {
        alert(data + ' | '+ data.validation);
        jQuery('.usercheck-w').remove();
        if (data.validation != 'true'){
            jQuery('.username-massage').html('<div class="alert alert-danger usercheck-c" style="color:red;">' + jQuery('#username').attr('data-value') + '</div>');
            jQuery("#username").val('');
        }else{
            jQuery('.usercheck-c').remove();
        }              

    },
});

});

and this is in my functions.php in my custom plugin. 

add_action('wp_ajax_checkUsernameExistentVal', 'checkUsernameExistentVal');
add_action('wp_ajax_nopriv_checkUsernameExistentVal', 'checkUsernameExistentVal');
function checkUsernameExistentVal(){
    $username = $_POST['username']; 
    $val = checkCOntactUsernameExist($username);
    $wp_users = get_users();
    $c_user = '';
    if ($val){
        $usernname_val= 'false';
    }else{
        foreach ($wp_users as $wp_user) {
            if($wp_user->user_login == $username){
                $c_user = 'true';
            }
        }
        if($c_user == 'true'){
            $usernname_val = 'false';
        }else{
            $usernname_val = 'true';
        }
    }

    echo json_encode(array("validation" => $usernname_val));
    wp_die();

}

my html code is <input type="text" name="username" id="username" value="">

does anyone have an idea about my case?

thanks in advance…

I check it in firebug and it got 302 Found

  1. The issue seems conflict with another plugin or function that is trying to prevent non logged in or non admin users access to the wp-admin area so it is redirecting from wp-admin/admin-ajax.php and giving you 302 response.

    Try deactivate each plugin one by one and check the issue.

  2. I put this code below the function and it works…

    if(isset($_REQUEST['action']) && $_REQUEST['action']=='ajaxFunctionMethod'){
        do_action( 'wp_ajax_' . $_REQUEST['action'] );
        do_action( 'wp_ajax_nopriv_' . $_REQUEST['action'] );
}
