Php files attached and not attached statment - php

Question

I have a code
if(count($_FILES) > 0) {
foreach($_FILES['fileAttach']['error'] as $status){
if($status === UPLOAD_ERR_OK) {
$fname[] = $_FILES['fileAttach']['name'][$Ccount];
$tmp_path[] = $_FILES['fileAttach']['tmp_name'][$Ccount];
$ftype[] = $_FILES['fileAttach']['type'][$Ccount];
}
$Ccount++;
}
} else { $fname[] = "0"; $tmp_path[] = "0"; $ftype[] = "0"; } // this not working
Then i want to use variables in function
SendEmails($ReCEmail,$strSubject,$strMessage,$txtFormName,$txtFormEmail,$fname,$ftype,$tmp_path);
It works until files is attached, but if no i got error Notice: Undefined variable: fname in ... on line ..
function SendEmails($vasia,$strSubject,$strMessage,$txtFormName,$txtFormEmail,$fname,$ftypes,$tmp_path) {
if(count($fname) == 0)
{ code without variables $fname,$ftypes,$tmp_path }
else {code with variables $fname,$ftypes,$tmp_path}
}
How to fix that?

Answer 1

if(count(array_filter($_FILES['fileAttach']['name'])) > 0) {
foreach($_FILES['fileAttach']['error'] as $key => $status){
if($status === 0) {
$fname[] = $_FILES['fileAttach']['name'][$key];
$tmp_path[] = $_FILES['fileAttach']['tmp_name'][$key];
$ftype[] = $_FILES['fileAttach']['type'][$key];
}
}
} else { $fname[] = "0"; $tmp_path[] = "0"; $ftype[] = "0"; }
and in your function change
if(count(array_filter($fname)) == 0)

If all $_FILES are error, then files array will be zero. So this error is printed
$fname[] = array();
$tmp_path[] = array();
$ftype[] = array();
foreach($_FILES['fileAttach']['error'] as $key => $status){
if($status === 0) {
$fname[] = $_FILES['fileAttach']['name'][$key];
$tmp_path[] = $_FILES['fileAttach']['tmp_name'][$key];
$ftype[] = $_FILES['fileAttach']['type'][$key];
}
}
if(count($fname)==0)
{ $fname[] = "0";$tmp_path[] = "0"; $ftype[] = "0"; }

Initialize your $fname array before the if:
$fname = array();
if($status === UPLOAD_ERR_OK) {
Confirm that your upload process is working by putting and echo after the if:
if($status === UPLOAD_ERR_OK) {
echo "Upload Status: " . $status . "<br>";
$fname[] = $_FILES['fileAttach']['name'][$Ccount];
If the echo output shows that $status != UPLOAD_ERR_OK, then $fname was not getting initialized, hence the Undefined variable error.
If the upload is failing, create another question containing the corresponding code snippets for that issue.
