This pipeline is used to add some content to SPIP’s exec/ pages. The new content is inserted after the content of the middle part of the page.

It is called as follows:

echo pipeline('affiche_milieu',array(


The plugin "Sélection d’articles" uses it to add a form to the sections page to offer a selection of articles:

function pb_selection_affiche_milieu($flux) {
    $exec = $flux["args"]["exec"];
    if ($exec == "naviguer") {
        $id_rubrique = $flux["args"]["id_rubrique"];
        $contexte = array('id_rubrique'=>$id_rubrique);
        $ret = "<div id='pave_selection'>";
        $ret .= recuperer_fond("selection_interface", $contexte);
        $ret .= "</div>";
        $flux["data"] .= $ret;

    return $flux;

The plugin "statistiques" adds a configuration form inside SPIP’s configuration pages.

function stats_affiche_milieu($flux){
    // displays the configuration ([de]activate the statistics).
    if ($flux['args']['exec'] == 'config_fonctions') {
        $compteur = charger_fonction('compteur', 'configuration');
        $flux['data'] .= $compteur();
    return $flux;
