A site can't actively search the user's hard drive. If you mean a Browse button, it does just that, lets the use browse his own drive for files to upload. It's created with <input type="file"> .

Which server-side scripting languages can you use?
Assuming that the user has submitted a real HTML form, you might use PHP http://php.net/manual/en/function.file-exists.php to check if the searched file exists, and then http://php.net/manual/en/function.file-get-contents.php to read its content and print on the form result page (or in a framed page, though I don't see the point with that). Note that when searching for a computer name, any typo may affect the search result. Also the user must spend time typing. Why not list all the files in the directory (say as a list of links) instead? This can be done with e.g. http://php.net/manual/en/function.scandir.php |

In php there is an instruction called file_exists( 'filename.and.type' ) which just returns a true or false if the 'fliename.and.type' file exists.
This can be used to implement a search for the desired file. if( file_exists( '/path/to/inv/file2.txt' ) ) { perform whatever; } This post has been edited by Ephraim F. Moya: May 4 2012, 10:26 PM |

You can send a redirect with the PHP header() function.

ok im stuck,
i want to check if the file name exist and if it does display a message AND print the contents of the file AND if the file DOES NOT exist display a message. here is my code: <?PHP $compname = $_POST['compname']; if (file_exists($compname)) { echo "NOTE: $compname exists in our inventory"; } elseif (file_exists($compname)) { (file_get_contents('$compname')); echo $compname; } else { echo "NOTE: $compname does NOT exists in our inventory"; } ?> |

That means that the first answer you get is the answer. And it's TRUE or FALSE. Doing it again will give you the same answer: The same TRUE or FALSE. If you're somehow getting three answers then you're doing something wrong. So your problem should be solved like this: if ( file_exists( $compname )) { echo "\nNOTE: $compname exists in our inventory\n"; $contents = file_get_contents( $compname ); echo "<br><br>" . $contents; } else { echo "NOTE: File $compname does NOT exist in our inventory"; } ps. Look for and read a basic php programming tutorial. Then read the whole thing over and over until it starts to make sense. This post has been edited by Ephraim F. Moya: May 10 2012, 10:04 PM |
