The HTML
copy<!-- IMPORTANT: FORM's enctype must be "multipart/form-data" -->
<form method="post" action="upload-page.php" enctype="multipart/form-data">
<input name="filesToUpload[]" id="filesToUpload" type="file" multiple="multiple" />
</form>
Simply adding the multiple attribute allows for multiple files to be uploaded via one INPUT element. If you're a stickler for validation, you'll want to assign the multiple attribute a value of multiple.
Listing Multiple Files with JavaScript
copy//get the input and UL list
var input = document.getElementById('filesToUpload');
var list = document.getElementById('fileList');
//empty list for now...
while (list.hasChildNodes()) {
list.removeChild(ul.firstChild);
}
//for every file...
for (var x = 0; x < input.files.length; x++) {
//add to list
var li = document.createElement('li');
li.innerHTML = 'File ' + (x + 1) + ': ' + input.files[x].name;
list.append(li);
}
The input.files property provides an array of files for which you can check the length; if there's a length, you can loop through each file and access the file paths and names.
Receiving and Handling Files with PHP
copyif(count($_FILES['uploads']['filesToUpload'])) {
foreach ($_FILES['uploads']['filesToUpload'] as $file) {
//do your upload stuff here
echo $file;
}
}
PHP creates an array of the files uploaded with the given INPUT's name. This variable will always be an array within PHP.
