Creare un'icona di ricerca con un tema

Ciao!

Stavo cercando di inserire un’icona accanto all’intestazione di ricerca per provare a imparare come inserire elementi in Discourse per iniziare.

Tuttavia, questo non ha funzionato.

<script>
node = document.getElementsByClassName('search-page-heading');
node.insertAdjacentElements('beforebegin', '<svg class="PixlzThemeSearchIcon" aria-hidden="true"><use xlink:href="#search"></use></svg>');
</script>

Potrebbe essere un errore stupido (come alcuni di voi sanno divento più stupido di notte), ma l’aiuto è apprezzato.
Grazie!

Ciao,

Se ho capito correttamente, vorresti aggiungere l’icona della ricerca qui nella pagina di ricerca

Penso che per farlo tu debba sovrascrivere il template di Discourse.
Ecco come fare: Sovrascrivere i template di Discourse, ma ti consiglio di leggere tutta la documentazione.

In questo caso, sembra qualcosa del genere. Per prima cosa devi trovare il template della pagina di ricerca. Ecco i template: https://github.com/discourse/discourse/tree/main/app/assets/javascripts/discourse/app/templates

Il template che stiamo cercando è full-page-search.hbs e possiamo chiaramente vedere quale parte modificare per apportare questa modifica.

Questa è la parte dell’intestazione del template che modificheremo… ma questo avverrà un po’ più tardi…

    <h1 class="search-page-heading">
      {{#if this.hasResults}}
        <div class="result-count" id="search-result-count" aria-live="polite">
          {{html-safe this.resultCountLabel}}
        </div>
      {{else}}
        {{i18n "search.full_page_title"}}
      {{/if}}
    </h1>

Ora, come sappiamo dalla documentazione sopra, dovremmo iniziare così:

Il template va nella sezione header.

<script type="text/x-handlebars" data-template-name="full-page-search">

</script>

Poi dobbiamo copiare l’intero template all’interno:

<script type="text/x-handlebars" data-template-name="full-page-search">
  <DSection @pageClass="search" @class="search-container">
    <ScrollTracker @name="full-page-search" @tag={{this.searchTerm}} @class="hidden" />

            {{html-safe this.resultCountLabel}}
          </div>
        {{else}}
          {{i18n "search.full_page_title"}}
        {{/if}}

Ora possiamo modificare la parte dell’intestazione di cui ho parlato prima. In questo caso si tratta di una modifica davvero semplice, ma puoi apportare modifiche più complesse. Assicurati che il tuo template personalizzato sia sempre aggiornato. Se ci sono modifiche nel template principale, dovresti aggiornare anche il tuo template personalizzato per far funzionare tutto correttamente.

In questo caso, aggiungiamo semplicemente un’icona {{d-icon "search"}} prima del titolo della pagina completa e prima del conteggio dei risultati.

Il template completo appare così

Spero che questo sia d’aiuto

Va bene, ha quasi funzionato!

Ho modificato il banner di ricerca e fa questo

Sì, penso che sia a causa del tuo CSS personalizzato. Probabilmente dovrai personalizzare quest’area.

Mi scuso per la risposta tardiva, ma questo è il CSS per questo.

svg.PixlzThemeSearchIcon {
      position: relative;
      display: table-row;
      height: 50px !important;
      width: 50px;
      top: 227px;
      left: 220px;
      fill: #e0e0e0;
}

C’è qualcosa che non va?

Ciao,

Non è necessario aggiungere CSS personalizzato all’SVG se vuoi che appaia prima del titolo, poiché lo abbiamo inserito nei tag <h2>, quindi utilizzerà gli stili di <h2>. Tuttavia, devi modificare la sezione del titolo di ricerca. Se non ricordo male, questo screenshot che hai condiviso sopra è del tuo tema DarkPixlz’s Modern Theme?

Ho controllato quel tema e penso che il problema sia che hai usato enormi padding e font-size per allineare il titolo al centro e non c’è abbastanza spazio per l’icona di ricerca.

.search-container .search-page-heading {
  padding: 2em 3.8em;
  font-size: 5em;
}

Il mio suggerimento:

Ho usato margini invece di padding, ma non sono necessari ai lati - poiché .search-header ha già un padding del 10% sui lati - per avere abbastanza spazio per l’icona e ho usato un font-size più piccolo, specialmente sui dispositivi mobili. Per correggere l’allineamento verticale, puoi aggiungere un margine di 1em in alto, poiché il tuo .main-outlet ha un padding di 3em in alto.

Probabilmente è meglio vedere se cambio lo sfondo.

Screenshot 2022-08-04 at 11.33.561182×524 99.1 KB

.search-container .search-page-heading {
  margin: 1em 0 2em 0;
  font-size: 5em; // usa un font-size più piccolo su schermi più piccoli
  text-align: center;
}

Grazie, ha funzionato
