php - Count the number of files selected for upload within multiple file fields -


i've wrote script user can select upload more 1 image form. i'm preventing user submitting form until of file fields have been added contain files upload.

eg:

the user has 3 file fields fill in, therefore 3 files must ready submission database.

i'm using same id on each of file upload fields. when use print_r($_files); returns me array. if browse file in first file field, , leave 2 blank, state array object [1] , [2] blank, [0] have name, type, size etc exists.

how go making sure of file fields filled in using php?

thanks in advance, rich

here efforts far:

$imgname1 = $_files['upload1']['name']; $imgtmp1 = $_files['upload1']['tmp_name']; $imgtype1 = $_files['upload1']['type']; $imgsize1 = $_files['upload1']['size'];  print_r($_files);  if(!$imgtmp1){ echo "<span class='error'>you need include @ least 1 image article.</span>";     exit();  } else {  $filecount=($_files['upload1']['name']); // attempt count file fields filled in  $cnt = $_post['cnt']; // number of file fields exist  echo "<br/>";  echo count($filecount); if($cnt != $filecount){ echo "<span class='error'>you have not uploaded of files.</span>"; exit(); }  // etc etc

you have incorrect upload checking. presence in $_files doesn't mean file uploaded. failed upload still create $_files entries.

you need check both presence of $_files entry, , error parameter:

if (isset($_files['upload1'])) {      if ($_files['upload']['error'] === upload_err_ok) {        ... file uploaded     } else {        ... upload failed     } } else {     ... no file upload attempted }
