Ahoj,
moc prosím o pomoc, co mám na tomto skriptu špatně. Skript slouží k sestavení "stromu" souborů a složek. Bohužel mi to ale vyhazuje tyto chyby: Notice: Undefined variable: php_file_tree on line 56 return $php_file_tree; Notice: Undefined variable: php_file_tree on line 7 $code .= php_file_tree_dir($directory, $return_link, $extensions); Prosím, pomůže mi někdo odhalit chybu v daných řádcích? MOC děkuju, M. <?php
function php_file_tree($directory, $return_link, $extensions = array()) {
// Generates a valid XHTML list of all directories, sub-directories, and files in $directory
// Remove trailing slash
if( substr($directory, -1) == "/" ) $directory = substr($directory, 0, strlen($directory) - 1);
$code .= php_file_tree_dir($directory, $return_link, $extensions);
return $code;
}
function php_file_tree_dir($directory, $return_link, $extensions = array(), $first_call = true) {
// Recursive function called by php_file_tree() to list directories/files

Dle mého názoru stačí pouze přidat ř.6 z kódu Taps.
Ostatní ponechte jak máte. Tedy: <?php
function php_file_tree($directory, $return_link, $extensions = array()) {
// Generates a valid XHTML list of all directories, sub-directories, and files in $directory
// Remove trailing slash
$code = '';
if( substr($directory, -1) == "/" ) $directory = substr($directory, 0, strlen($directory) - 1);
$code = php_file_tree_dir($directory, $return_link, $extensions);
return $code;
}Důvod chyby: pokud podmínka není splněna, neexistuje proměnná $code a return nemá co vrátit (err ř. 11), protože je funkce volána z ř. 56, tak tam nastane chyba protože se nic nevrátí.. Navíc přičítat řetězec k něčemu co neexistuje vrací také chybu $code .=

Ta lokální proměnná nebude existovat nikdy, proč tam nedáte normální přiřazení? Resp. hned return? $code tam vůbec není potřeba.
A ta podmínka by šla nahradit pomocí rtrim, celou funkci bych zkrátil na jeden řádek. |

Ahoj, děkuju za reakce.
Bohužel řešení od Tapse a Lonanka nefunguje :-(. Zkusil jsem tedy řešení dle Alpharda (snad jsem to dobře pochopil? doufám...) - dal jsem ze 7. řádku pryč $code a místo něj tam dal rovnou return. Chyba ze 7. řádku zmizela, ale na 56. se pořád ukazuje. A to už fakt nevím, jak opravit :-(. Takto jsem opravil 7. řádek <?php
function php_file_tree($directory, $return_link, $extensions = array()) {
// Generates a valid XHTML list of all directories, sub-directories, and files in $directory
// Remove trailing slash
if( substr($directory, -1) == "/" ) $directory = substr($directory, 0, strlen($directory) - 1);
return php_file_tree_dir($directory, $return_link, $extensions);
}
function php_file_tree_dir($directory, $return_link, $extensions = array(), $first_call = true) {
// Recursive function called by php_file_tree() to list directories/files
// Get and sort directories/files
if( function_exists("scandir") ) $file = scandir($directory); else $file = php4_scandir($directory);
natcasesort($file);
// Make directories first
$files = $dirs = array();
foreach($file as $this_file) {
if( is_dir("$directory/$this_file" ) ) $dirs[] = $this_file; else $files[] = $this_file;
}
$file = array_merge($dirs, $files);
// Filter unwanted extensions
if( !empty($extensions) ) {
foreach( array_keys($file) as $key ) {
if( !is_dir("$directory/$file[$key]") ) {
$ext = substr($file[$key], strrpos($file[$key], ".") + 1);
if( !in_array($ext, $extensions) ) unset($file[$key]);
}
}
}
if( count($file) > 2 ) { // Use 2 instead of 0 to account for . and .. "directories"
$php_file_tree = "<ul";
if( $first_call ) { $php_file_tree .= " class=\"file-tree\""; $first_call = false; }
$php_file_tree .= ">";
foreach( $file as $this_file ) {
if( $this_file != "." && $this_file != ".." ) {
if( is_dir("$directory/$this_file") ) {
// Directory
$php_file_tree .= "<li class=\"ft-directory\"><a href=\"#\">" . htmlspecialchars($this_file) . "</a>";
$php_file_tree .= php_file_tree_dir("$directory/$this_file", $return_link ,$extensions, false);
$php_file_tree .= "</li>";
} else {
// File
// Get extension (prepend 'ext-' to prevent invalid classes from extensions that begin with numbers)
$ext = "ext-" . substr($this_file, strrpos($this_file, ".") + 1);
$link = str_replace("[link]", "$directory/" . urlencode($this_file), $return_link);
$php_file_tree .= "<li class=\"ft-file " . strtolower($ext) . "\"><a href=\"$link\" target=\"_blank\">" . htmlspecialchars($this_file) . "</a></li>";
}
}
}
$php_file_tree .= "</ul>";
}
return $php_file_tree;
}
// For PHP4 compatibility
function php4_scandir($dir) {
$dh = opendir($dir);
while( false !== ($filename = readdir($dh)) ) {
$files[] = $filename;
}
sort($files);
return($files);
}

Zkuste na ř. 12 vložit:
$php_file_tree = ""; |

Ooooo, děkuju moc! :-)
Chyba na 56. řádku je nyní pryč, paráda :-). |
