Salve ragazzi:
Un utente deve visualizzare in una pagina di wordpress questa struttura ad albero dei file: deve vedere il contenuto di una specifica cartella su wordpress, deve riuscire ad esplorare e aprire i file eventualmente contenuti.
Ho scaricato questo script: https://www.abeautifulsite.net/php-file-tree e l'ho inserito nella cartella htdocs con xampp per vedere se localmente mi funziona.
L'esito � negativo, mi appare s�, la struttura ad albero dei file, ma non si pu� fare il collapse, cio� non posso chiudere ed aprire le cartelle in quanto risultano gi� tutte aperte. Inoltre mi appare una serie di errori:
Undefined variable: php_file_tree in H:\xampp\htdocs\Tree\php_file_tree.php on line 73
Undefined variable: code in H:\xampp\htdocs\Tree\php_file_tree.php on line 24
La cartella dello script � composta dai seguenti file:
- demo_jquery.php
- php_file_tree.php
- php_file_tree_jquery.js
Il contenuto di demo_jquery.php � questo:

Invece il contenuto di php_file_tree_jquery.js � questo:

[/spoiler]codice:$(document).ready( function() { // Hide all subfolders at startup $(".php-file-tree").find("UL").hide(); // Expand/collapse on click $(".pft-directory A").click( function() { $(this).parent().find("UL:first").slideToggle("medium"); if( $(this).parent().attr('className') == "pft-directory" ) return false; }); });
Considerando che mi trovo in difficolt� in quanto non ho mai programmato, chiedo il vostro aiuto per riuscire a far funzionare questa cosa.
Ringrazio tutti coloro che mi risponderanno!
