I have a php form with unknown number of rows where user can upload files. For this purpose I use two dimensional array.
<form action="upload_file_module.php" method="post" enctype="multipart/form-data">
<? $i = 0; ?>
<table>
<tr>
<td>
<input type="hidden" name="row[<? echo $i; ?>][row_name]" value = "one"/> One
</td>
<td>
<input type="file" name="row[<? echo $i; ?>][fileToUpload]" >
</td>
<?
$i++;
?>
</tr>
<tr>
<td>
<input type="hidden" name="row[<? echo $i; ?>][row_name]" value = "two"/> Two
</td>
<td>
<input type="file" name="row[<? echo $i; ?>][fileToUpload]" >
</td>
<?
$i++;
?>
</tr>
</table>
<input type="submit" value="Upload" name="submit">
All files should be saved in different folders.
<?php
$unique_id = "folder";
$unique_id = $unique_id . '/';
foreach ( $_POST['row'] as $val ) {
$target_dir = $unique_id;
$target_dir = $target_dir . "/" . $val. "/";
if (!file_exists($target_dir)) {
mkdir($target_dir, 0777, true);
}
echo '<table>';
echo '<tr>';
echo '<td>', $val['row_name'], '</td>';
echo '<td>', $val['fileToUpload'], '</td>';
echo '</tr>';
echo '</table>';
$target_file = $target_dir . basename($_FILES[$val['fileToUpload']]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
// Check if file already exists
if (file_exists($target_file)) {
echo "Sorry, file already exists.";
$uploadOk = 0;
}
// Check file size
if ($_FILES["fileToUpload"]["size"] > 900000000) {
echo "Sorry, your file is too large.";
$uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.<br>";
} else {
echo "Sorry, there was an error uploading your file.<br>";
}
}
}
But in fact it doesn't see any files, and output looks like:
one
Sorry, file already exists.Sorry, your file was not uploaded.
two
Sorry, file already exists.Sorry, your file was not uploaded.
There were some changes to be made, in addition to the ones in the comments. Major issues are:
$_POST and $_FILES are, in PHP nature, totally separated entities. So you're ending up trying to access a single array row when there is actually two row arrays inside both these superglobals.$target_file was never declared, and your $target_dir has too many slashes.$val the wrong way.These are the final corrections I came up with, keeping the logic for your own environment. The explanation to each part is commented inside the code.
HTML form

<form action="upload.php" method="post" enctype="multipart/form-data">

<?php $counter = 2; // number of fields you want to be printed
for($i = 0; $i < $counter; $i++): // do proper counting ?>

<input type="hidden" name="row[]" value="<?php echo $i; ?>"/> File:

<input type="file" name="row[]" >

$target_dir = $target_dir . $val. "/"; // no need to index assoc nor '/'
if (!file_exists($target_dir)) {
mkdir($target_dir, 0777, true);
}
$imageFileType = pathinfo($target_dir,PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
// Check if file already exists
if (file_exists($target_file)) {
die("Sorry, file already exists."); // die if error
}
// Check file size
if ($_FILES['row']['size'][$val] > 900000000) { // using the proper index reference for file
die("Sorry, your file is too large."); //die if error
}
// Check if there are error msg in $_FILES
if ($_FILES['row']['error'][$val] != 0) {
die("Sorry, your file was not uploaded."); // die if error
// if everything is ok, try to upload file
} else {
// point your move_files with the final name of the actual file to be moved
if (move_uploaded_file($_FILES['row']['tmp_name'][$val], $target_dir.'/'.$_FILES['row']['name'][$val])) {
echo "The file ". basename($_FILES['row']['name'][$val]). " has been uploaded.<br>";
} else {
die("Sorry, there was an error uploading your file.");
