计算上传文件的数量

Question

I want to count number of uploaded file but I'm unable to get the error if no file had been uploaded. Here is my code for reference:

html

<input type="file" name="file[]" class="filestyle" data-buttonText="Quotation 1" multiple="multiple">

php

$total = count($_FILES['file']['name']);
if($total > '2'){
    for($i=0; $i<$total; $i++){
        $tmpFilePath = $_FILES['file']['tmp_name'][$i];
        if($tmpFilePath != ""){
           $shortname = $_FILES['file']['name'][$i];
           $filePath = "uploads/" . date('d-m-Y-H-i-s').'-'.$_FILES['file']['name'][$i];
           if(!$msgError && move_uploaded_file($tmpFilePath, $filePath)){
                // insert to db and success msg 
        }
    }
} elseif($total < '4') {    
    $msgError[] = "Need to upload 3 Quotations";    
}
if(isset($msgError)){
    $msgErrorString = implode(",",$msgError); 
    header("Location: pr_form.php?msgError=".$msgErrorString."");
}

If user upload less than 3 files, the error will not appear. I have other validations for user input. Everything is working except for the file validation. May I know why?

Answer 1

First: Remove the '

$total > '2' should be $total > 2

same with total < 4

Second:

It should be

count($_FILES) not count($_FILES['file']['name'])

So, in your problem ..

if no file had been uploaded.

$total = count($_FILES);
if($total > 2){
    for($i=0; $i<$total; $i++){
        $tmpFilePath = $_FILES['file']['tmp_name'][$i];
        if($tmpFilePath != ""){
           $shortname = $_FILES['file']['name'][$i];
           $filePath = "uploads/" . date('d-m-Y-H-i-s').'-'.$_FILES['file']['name'][$i];
           if(!$msgError && move_uploaded_file($tmpFilePath, $filePath)){
                // insert to db and success msg 
        }
    }
} elseif($total < 4 && $total > 0) {    
    $msgError = "Need to upload 3 Quotations";    
}
elseif($total === 0){ //This condition
    $msgError = "No chosen file."; 
}
if(isset($msgError)){
    header("Location: pr_form.php?msgError=".$msgError."");
}

And then in your pr_form.php, you should have something like this line..

<?php 
   echo $_GET['msgError'];
?>
