PHP Mcdropdown implementation file path can be selected in the dropdown box method

Gets the list of files in the specified directory $path The specified directory, default to the current directory $ifchild whether to display a list of subdirectory files, which are not displayed by default $curpath Displays the current path, which is the default starting from the current directory; This is primarily to show the determination of the HREF path function Openpath ($path = ".", $ifchild =false, $curpath = ".") { $handle = Opendir ($path); if ($handle) { while (false!== ($file = Readdir ($handle))) { if ($file! = "." && $file! = "...") { $fullPath = $path. Directory_separator. $file; if (Is_dir ($fullPath))//If it is a directory file { if ($ifchild)//If the display subdirectory is set { Recursive Openpath ($path. Directory_separator. $file, $ifchild, $curpath. Directory_separator. $file); } Else { echo " $file \ n "; } } else if ($file! = basename (__file__))//Exclude Current execution script { echo " $file \ n "; } Else { Echo $file; } } } } Closedir ($handle); } Copy Code Because you want to provide the function of the path selection, if there is a drop-down menu, it is OK to select the path to display. 2. Obtain the code for all sub-file paths under the current file: /* Get a list of specified directory file paths * $path The specified directory, default to the current directory * $ifchild whether to get a list of subdirectory files, which is not acquired by default * $curpath Displays the current path, which defaults to starting from the current directory *& $pach _html_srt to pass in a reference to an external variable, because this method might be called recursively, so save it in this way * Some information can also be implemented with global variables, and changes in the function internal variables also affect the external. *& $path _ref_count principle, a count flag, if recursive, the counter from the last saved value from the beginning of the increment */ function Openpath ($path = ".", $ifchild =false,& $path _html_str,& $path _ref_count) { $handle = Opendir ($path); if ($handle) { while (false!== ($file = Readdir ($handle))) { if ($file! = "." && $file! = "...") { $fullPath = $path. Directory_separator. $file; if (Is_dir ($fullPath))//If the file is a directory { $path _html_str.= ' '; $path _html_str.= $file. ' '; if ($ifchild) { Recursive Openpath ($path. Directory_separator. $file, $ifchild,& $path _html_str,& $path _ref_count); } $path _html_str.= ' '; } } } } Closedir ($handle); } Copy Code With the above method, you can use the jquery Mcdropdown plugin in the foreground to allow the user to select the desired directory from the drop-down menu, so it needs to be encapsulated in the specified format: $path _ref_count = 1; $path _html_str = "; Openpath (".",true,& $path _html_str,& $path _ref_count); $path _html_str = " . $path _html_str." ; $path _html_str = Str_replace (" ", "", $path _html_str); ?> Copy Code This $path_html_str to the foreground, which shows a list of unordered lists that meet the requirements of mcdropdown, and can display the corresponding list of choices. The complete code is as follows: 1, test.html jquery Mcdropdown implements a file path that can be selected in the dropdown box _bbs.it-home.org Please select a Category: #categorymenu # Copy Code 2, test.php Directory Information Processing $path _ref_count = 1; $path _html_str = "; Openpath (".",true,& $path _html_str,& $path _ref_count); $path _html_str = " . $path _html_str." ; $path _html_str = Str_replace (" ", "", $path _html_str); Var_dump ($path _info); Var_dump ($path _html_str); $str _buffer = file_get_contents (dirname (__file__).
