Uploading multiple filesPodręcznik PHPPoprzedniRozdział 19. Handling file uploadsNastępnyUploading multiple files
Multiple files can be uploaded using different
name for input.
It is also possible to upload multiple files simultaneously and
have the information organized automatically in arrays for you. To
do so, you need to use the same array submission syntax in the
HTML form as you do with multiple selects and checkboxes:
Notatka:
Support for multiple file uploads was added in version 3.0.10.
Przykład 19-3. Uploading multiple files<form action="file-upload.php" method="post" enctype="multipart/form-data">
Send these files:<br>
<input name="userfile[]" type="file"><br>
<input name="userfile[]" type="file"><br>
<input type="submit" value="Send files">
</form>
When the above form is submitted, the arrays
$HTTP_POST_FILES['userfile'],
$HTTP_POST_FILES['userfile']['name'], and
$HTTP_POST_FILES['userfile']['size'] will be
initialized. (As well as in $_FILES for PHP 4.1.0 or
later. $HTTP_POST_VARS in PHP 3. When
register_globals is on, globals for uploaded
files are also initialized). Each of these will be a numerically
indexed array of the appropriate values for the submitted files.
For instance, assume that the filenames
/home/test/review.html and
/home/test/xwp.out are submitted. In this
case, $HTTP_POST_FILES['userfile']['name'][0]
would contain the value review.html, and
$HTTP_POST_FILES['userfile']['name'][1] would
contain the value xwp.out. Similarly,
$HTTP_POST_FILES['userfile']['size'][0] would
contain review.html's filesize, and so forth.
$HTTP_POST_FILES['userfile']['name'][0],
$HTTP_POST_FILES['userfile']['tmp_name'][0],
$HTTP_POST_FILES['userfile']['size'][0], and
$HTTP_POST_FILES['userfile']['type'][0] are
also set.
