Custom Form Error in Symfony 5 (form_errors)

While you can add attributes to form_label and form_widget to customise form_errors you have to use a template. Add a twig template "templates/form/form_errors.html.twig" Paste in the below {% block form_errors %}     {% if errors|length > 0 %}     <ul class="error_list">         {% for error in errors %}             <li>{{ error.message }}</li>         {% endfor %}     </ul>     {% endif %} {% endblock form_errors %} Edit "config/packages/twig.yaml" Add in the template details eg. twig:     default_path: '%kernel.project_dir%/templates'     form_themes:         - 'form/form_errors.html.twig' Based on Symfony 2 instructions found here

Using variables within ajax success function that were set before ajax call (JQuery)

I spent several hours trying to access variables that were set before an Ajax call, turns out there is a simple solution. To be able to access the variables you need to set them as parameters within the Ajax call and then to access them in the success function you prefix them with "this." eg. var a = 1; $.ajax({             type: "POST",             contentType: "application/json; charset=utf-8",             url: "theurl.com",             data: '{a: a}',             dataType: "json",             a: a,             success: function (msg) {                     var arr = eval(msg.d);                     process(arr, this.a );             }         });
