kohana/php parse $_FILES vector - php

Question

i want to parse a $_files vector in order to make a multiple upload.
i try like this:
for($i=0; $i < count($_FILES['product_image']);$i++){PRINT_R($_FILES['product_image'][$i]);
but it gives me the error: Undefined offset: 0 in /Users.... etc then the same for 1, 3, etc.
in the form i have: three fields:
<input id="product_image" type="file" name="product_image[]" >
<input id="product_image" type="file" name="product_image[]" >
<input id="product_image" type="file" name="product_image[]" >
i wonder where am i wrong? wht can't i parse the $_files vector?

Answer 1

Did you try using a foreach loop ?
See Example 3 for file upload on PHP site:
<form action="" method="post" enctype="multipart/form-data">
<p>Pictures:
<input type="file" name="pictures[]" />
<input type="file" name="pictures[]" />
<input type="file" name="pictures[]" />
<input type="submit" value="Send" />
</p>
</form>
<?php
foreach ($_FILES["pictures"]["error"] as $key => $error) {
if ($error == UPLOAD_ERR_OK) {
$tmp_name = $_FILES["pictures"]["tmp_name"][$key];
$name = $_FILES["pictures"]["name"][$key];
move_uploaded_file($tmp_name, "data/$name");
}
}
?>
EDIT:
Maybe your first loop could work like this:
$files_count = count($_FILES['product_image']['error']);
for($i = 0; $i < $files_count; $i++)
{
//...
}
