string searchAndRenderBlock(FormView $view, string $blockNameSuffix, array $variables = array()) Searches and renders a block for a given name suffix. The block is searched by combining the block names stored in the form view with the given suffix. If a block name is found, that block is rendered. If this method is called recursively, the block search is continued where a block was found before. Parameters FormView $view The view for which to render the block string $blockNameS

string renderCsrfToken(string $tokenId) Renders a CSRF token. Use this helper for CSRF protection without the overhead of creating a form. Check the token in your action using the same token ID. $csrfProvider = $this->get('security.csrf.tokengenerator'); if (!$csrfProvider->isCsrfTokenValid('rmuser_'.$user->getId(), $token)) { throw new \RuntimeException('CSRF attack detected.'); } Parameters string $tokenId The ID of the CSRF token Return Value string A CSRF to

string renderBlock(FormView $view, string $blockName, array $variables = array()) Renders a named block of the form theme. Parameters FormView $view The view for which to render the block string $blockName The name of the block array $variables The variables to pass to the template Return Value string The HTML markup

int|bool getResourceHierarchyLevel(FormView $view, array $blockNameHierarchy, int $hierarchyLevel) Returns the hierarchy level at which a resource can be found. A block hierarchy is an array which starts with the root of the hierarchy and continues with the child of that root, the child of that child etc. The following is an example for a block hierarchy: formwidget textwidget url_widget The second parameter $hierarchyLevel determines the level of the hierarchy that should be r

mixed getResourceForBlockNameHierarchy(FormView $view, array $blockNameHierarchy, int $hierarchyLevel) Returns the resource for a block hierarchy.
