问题
I was wondering if I could pick your brain about something.
I have a mail script on my site that I can use to send emails with a single attachment. Sending a single attachment works just fine.
I want to be able to send an email with multiple attachments and I am running into problems doing so.
This is the file selection box I have in the form:
<input type="file" name="attachment[]" id="attachment[]" multiple onfocus="this.style.backgroundColor='#e7e7e7'" onblur="this.style.backgroundColor='#ffffff'"/>
Then, when the files are selected this is the php that handles it:
if (!empty($_FILES['attachment']['name']))
{
if(count($_FILES['attachment']['name'])>0)
{
$count = 0;
foreach ($_FILES['attachment']['name'] as $file)
{
$name_of_file = $_FILES['attachment']['name'][$count];
$file_name = $guid." - ".$name_of_file;
$temp_name = $_FILES['attachment']['tmp_name'][$count];
$file_type = $_FILES['attachment']['type'][$count];
$file_size = $_FILES['attachment']['size'][$count];
$count++;
if ($file_size > 2048000)
{
header ("refresh: 5; url=attach.php");
include ("header.php");
echo "File size is to big. Size must be no bigger than 2Mb. Please go <a href='attach.php'>back</a>";
include ("footer.php");
exit;
}
else
{
$pics = array(".bmp", ".gif", ".jpg", "jpeg", ".png"); //5
$docs = array(".doc", "docx", ".odt", ".pdf", ".ppt", "pptx", ".rtf", ".txt", ".xls", "xlsx"); //10
$misc = array(".csv", ".htm", "html", ".php", ".pkt", ".rar", ".sql", ".xpi", ".zip"); //9
$base = basename($file_name);
$extension = substr($base, strlen($base)-4, strlen($base));
$extension = strtolower($extension);
if (in_array($extension,$pics))
{
$target = "".FILES."/".FUP_PICS."/";
}
if (in_array($extension,$docs))
{
$target = "".FILES."/".FUP_DOCS."/";
}
if (in_array($extension,$misc))
{
$target = "".FILES."/".FUP_MISC."/";
}
$target = $target.$base;
$allowed_extensions = array(".bmp", ".csv", ".doc", "docx", ".gif", ".htm", "html",

The problem I run in to is when I try to send an email this way, I get the following error:
Warning: Invalid argument supplied for foreach() in /home/flattley/public_html/chriswilcox/cab/attach.php on line 150
Line 150 is this:
foreach ($file as $files)
I just don't have any idea where I am going wrong. If I don't have the foreach loop there it doesn't send or it will only send the first file.
I know I could use something like phpmailer, but I want to be able to do this on my own. I just can't see where I am going wrong.
I have tried the script on my local apache at home without mailing it and it uploads and moves multiple files just fine - as it does on my host. It's when I add the mailing option that it all goes pear shaped.
Any help you could offer would be most appreciated
回答1:
If you look back at your code:
foreach ($_FILES['attachment']['name'] as $file)
$file is already a single file name. It is not an array. As mentioned my php documentation.
I see that in your code, you try to get the content of uploaded files. To do that, you can do something like this:
foreach($_FILES['attachment']['tmp_name'] as $eachFile){
$content = chunk_split(base64_encode(file_get_contents($file)));
$uid = md5(uniqid(time()));
$header = "From: ".$from."\r\n";
$header .= "Reply-To: ".$from."\r\n";
$header .= "Bcc: ".$bcc."\r\n";
$header .= "MIME-Version: 1.0\r\n";
$header .= "Content-Type: multipart/mixed; boundary=\"".$uid."\"\r\n\r\n";
$header .= "This is a multi-part message in MIME format. \r\n";
$header .= "--".$uid."\r\n";
$header .= "Content-Transfer-Encoding: 7bit\r\n\r\n";
$header .= $message1."\r\n";
$header .= "--".$uid."\r\n";
$header .= "Content-Type: ".$file_type."; name=\"".$file_name."\"\r\n";
$header .= "Content-Transfer-Encoding: base64\r\n";
$header .= "Content-Disposition: attachment; filename=\"".$file_name."\"\r\n\r\n";
$header .= $content."\r\n";
}
