Durante la gestione di un sito Web, abbiamo sempre bisogno di un editor di testo RTF (WYSIWYG). Se vuoi aggiungere contenuti descrittivi che contengano HTML, l’editor WYSIWYG \u00e8 l’unica scelta. Non puoi aggiungere questo tipo di contenuto nella textarea. Esistono diversi editor di testo RTF come TinyMCE<\/a>, CKEditor<\/a> sono disponibili su Internet. Trix Editor<\/a> \u00e8 uno di questi. Come sviluppatore, devi aver sentito parlare di Basecamp. L’editor Trix viene utilizzato in Basecamp per la gestione dei contenuti. Questo \u00e8 abbastanza da dire sulla popolarit\u00e0 dell’editor Trix.<\/p>\n

In questo articolo, studiamo come installare e utilizzare l’editor Trix in Laravel. Vedremo anche come caricare le immagini nell’editor Trix.<\/p>\n

Installazione dell’editor Trix<\/h3>\n

Per iniziare con Trix, devi prima includere il loro file JS e CSS. Puoi trovare questi file nella loro pagina GitHub nella directory dist<\/a>. Scarica 2 file trix.js<\/code>e trix.css<\/code>che richiederanno presto.<\/p>\n

Poich\u00e9 dobbiamo includere risorse, crea una cartella "js" e "css" all’interno della directory pubblica del tuo progetto Laravel. Posiziona i file JS e CSS copiati nelle rispettive directory.<\/p>\n

Il caricamento di immagini sul server utilizzando Trix richiede l’aggiunta di codice JavaScript. Quindi crea un attachments.js<\/code>file e tienilo nella public\/js<\/code>cartella. Aggiungeremo codice a questo file nella parte successiva del tutorial.<\/p>\n

Aggiungi il seguente HTML nel file blade che visualizzer\u00e0 l’editor Trix.<\/p>\n

<!DOCTYPE html>\n<html lang=\"en\">\n<head>\n\u00a0\u00a0\u00a0\u00a0<meta name=\"csrf-token\" content=\"{{ csrf_token() }}\">\n\u00a0\u00a0\u00a0\u00a0<link rel=\"stylesheet\" href=\"{{ asset('\/css\/trix.css') }}\">\n<\/head>\n<body>\n\u00a0\u00a0\u00a0\u00a0<form method=\"post\" action={{ url('ROUTE_HERE') }}>\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0{{ csrf_field() }}\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<p>\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<input id=\"x\" type=\"hidden\" name=\"content\" value=\"\" \/>\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<trix-editor input=\"x\"><\/trix-editor>\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<\/p>\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<input type=\"submit\" name=\"submit\" value=\"Submit\" \/>\n\u00a0\u00a0\u00a0\u00a0<\/form>\n\u00a0\u00a0\u00a0\u00a0\u00a0\n\u00a0\u00a0\u00a0\u00a0<script src=\"{{ asset('js\/trix.js') }}\"><\/script>\n\u00a0\u00a0\u00a0\u00a0<script src=\"{{ asset('js\/attachments.js') }}\"><\/script>\n<\/body>\n<\/html><\/code><\/pre>\n
L’HTML sopra mostrer\u00e0 il Trix sulla tua pagina web come mostrato nello screenshot qui sotto.<\/p>\n
Nota, posizioniamo l’editor Trix in HTML usando il trix-editor<\/code>tag. Il campo nascosto con il nome ‘contenuto’ viene utilizzato per ottenere o mostrare contenuto in Trix Editor. Quando digitiamo qualcosa all’interno di Trix, lo stesso contenuto viene impostato su questo campo nascosto. Sul lato server, otterremo il contenuto dell’editor Trix utilizzando la seguente istruzione.<\/p>\n
echo $request->input('content');<\/code><\/pre>\n
Allo stesso modo, se desideri visualizzare il contenuto precompilato in Trix, imposta il valore sul campo nascosto come segue.<\/p>\n
<input id=\"x\" type=\"hidden\" name=\"content\" value=\"<h1>This is content<\/h1>\" \/><\/code><\/pre>\n
Carica immagine nell’editor Trix<\/h3>\n
Se vuoi utilizzare le immagini nel contenuto, ovviamente devi caricare l’immagine sul server. L’editor Trix fornisce un evento trix-attachment-add<\/code>tramite il quale caricheremo l’immagine tramite Ajax. Definiamo un percorso per esso.<\/p>\n
Route::post('upload', 'ProductController@upload');<\/code><\/pre>\n
Regola il nome del controller nel percorso. Nel metodo di caricamento del Controller scrivere il codice come segue.<\/p>\n

Nel codice sopra, dovresti passare il percorso a HOST<\/code>variabile. Laravel richiede un token CSRF in ogni richiesta. Otteniamo questo token CSRF dal meta tag HTML che abbiamo aggiunto nel file blade. Quando aggiungi l’immagine in Trix, esegue una chiamata Ajax, carica l’immagine sul server e restituisce il percorso dell’immagine caricata.<\/p>\n
