PHP-General - Issue with $_FILES

Hi,

I have a strange issue in a script for uploading images.
I have a page to modify products.
The logic function of the page is that if I do not select the modification of the image product, the script "skip" the code to upload and continues with the rest of the script.
I put a check on $ _FILES after sending the form, but the result is
$ _FILES ['FleImage'] ['name'] is always NOT empty.
but print_r ($ _FILES) say to me that array is empty.

PHP Code:


		
			
echo"<pre>"; 

print_r($_FILES); 

echo"</pre>"; 



$name = $_FILES['fleImage']['name']; 

if (empty($name)) { echo "is empty"; 

} 

else 

{ 

echo "is not empty";}

then i created a simple test page with forms and controls equal to the original page:

PHP Code:


		
			
<!DOCTYPE html> 

<html> 

<head> 

<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> 

</head> 

<body> 



<form action="" method="post" enctype="multipart/form-data" name="prova"> 

<input name="fleImage" type="file" id="fleImage" class="box" multiple="multiple"> 

<input name="modify" type="submit" value="Modify Product"> 

</form> 



<?php echo"<pre>"; 

print_r($_FILES); 

echo"</pre>"; 



$name = $_FILES['fleImage']['name']; 

if (empty($name)) 

{ 

echo "is empty"; 

} else {

echo "is not empty";} ?> 



</body> 

</html>

and this example works correctly!
Why?

Use '!isset' rather than 'empty'.

hi gw1500se,

I used !isset($name) but does not work..

Selecting an image:

Code:

Array ( 
[fleImage] => Array 
( [name] => Array ( [0] => IMG_0219.JPG ) 
[type] => Array 
( [0] => image/jpeg ) 
[tmp_name] => Array 
( [0] => E:\xampp\tmp\php2D01.tmp ) 
[error] => Array ( [0] => 0 ) 
[size] => Array ( [0] => 3311146 ) 
) 
)

result: is isset

NOT Selecting an image:

Code:

Array ( 
[fleImage] => Array 
( [name] => Array ( [0] => )
 [type] => Array ( [0] => ) 
[tmp_name] => Array ( [0] => )
 [error] => Array ( [0] => 4 ) 
[size] => Array ( [0] => 0 ) 
) 
)

result: is isset

Use it to check $_FILES before setting $name.

Does not work ..
I try to summarize the entire operation:

form

Code:

<form action="processProduct.php?action=modifyProduct&productId=<?php echo $productId; ?>" method="post" enctype="multipart/form-data" name="frmAddProduct" id="frmAddProduct">

At the submit i send everything to the file processProduct.php

PHP Code:


		
			
 $action = isset($_GET['action']) ? $_GET['action'] : '';

 switch ($action) {

case 'modifyProduct' :

        test();

        break;

}



function test()

{





echo"<pre>";

print_r($_FILES);

echo"</pre>";



if (!isset($_FILES['fleImage']['name'])) {



echo "is empty"; 

} else {

echo "is not empty";

}

 }

and that's it ... but it does not work

I do not understand why the test page I posted beginning of this thread works perfectly and this test do not work...

The control on $_FILES!

i used empty() and !isset()
i send data from the form with and without images (checked with print_r ) but result is always "is not empty"!
