It is 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:
Note:
Support for multiple file uploads was added in version 3.0.10.
Example 19-2. Uploading multiple files
<form action="file-upload.html" 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
$userfile,
$userfile_name, and
$userfile_size will be formed in
the global scope (as well as in $HTTP_POST_FILES ($HTTP_POST_VARS
in PHP 3)). 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, $userfile_name[0] would
contain the value review.html,
and $userfile_name[1] would
contain the value
xwp.out. Similarly,
$userfile_size[0] would contain
review.html's filesize, and so forth.
$userfile['name'][0],
$userfile['tmp_name'][0],
$userfile['size'][0], and
$userfile['type'][0] are also set.
