Option to add file or not

[runnerjp]

ok so i have my form and in it you can add a entry form via an upload.

 

The thing is its just an option so when i run my script

 

<?php
ini_set("display_errors", "1");
error_reporting(E_ALL);

if ((($_FILES["file"]["type"] == "application/msword"))
&& ($_FILES["file"]["size"] < 500000))
  {
  if ($_FILES["file"]["error"] > 0)
    {
    echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
    }
  else
    {
    echo "Upload: " . $_FILES["file"]["name"] . "<br />";
    //echo "Type: " . $_FILES["file"]["type"] . "<br />";
   // echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
   // echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />";

    if (file_exists("entrys/" . $_FILES["file"]["name"]))
      {
      echo $_FILES["file"]["name"] . " already exists. ";
      }
    else
      {
      move_uploaded_file($_FILES["file"]["tmp_name"],
      "entrys/" . $_FILES["file"]["name"]);
      echo "Stored in: " . "entrys/" . $_FILES["file"]["type"];
      }
    }
  }
else
  {
  echo "Invalid file".$_FILES["file"]["name"];
  }

//print_r($_REQUEST['form']);





?>

 

to obvius im going to get  echo "Invalid file".$_FILES["file"]["name"];. Is there away to check if there is any information within the <div><label>File:</label> <input type="file" name="file" /></div> and if not dont run the file script? 

 

Just to add i want everything to work off this script so adding names ect so form looks like this

 

 <form  action="/include/addfixture.php" method="post" onsubmit="return AIM.submit(this, {'onStart' : startCallback, 'onComplete' : completeCallback})"enctype="multipart/form-data">
      <div><label>Name:</label> <input type="text" name="name" /></div>
      <div><label>File:</label> <input type="file" name="file" /></div>
      <div><label>Email:</label> <input type="text" name="email" /></div>
      <div><label>Event:</label> <input type="text" name="event" /></div>
      <div><label>Venue:</label> <input type="text" name="venue" /></div>

      <div><input type="submit" name="form"value="SUBMIT" /></div>

You could wrap the whole thing with:

 

if (isset($_FILES['file']))
{

    // ...

}

 

.. If I understand you right.

I tried that with

 

if (isset($_FILES['file']))
{
if ((($_FILES["file"]["type"] == "application/msword"))
&& ($_FILES["file"]["size"] < 500000))
  {
  if ($_FILES["file"]["error"] > 0)
    {
    echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
    }
  else
    {
    echo "Upload: " . $_FILES["file"]["name"] . "<br />";
    //echo "Type: " . $_FILES["file"]["type"] . "<br />";
   // echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
   // echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />";

    if (file_exists("entrys/" . $_FILES["file"]["name"]))
      {
      echo $_FILES["file"]["name"] . " already exists. ";
      }
    else
      {
      move_uploaded_file($_FILES["file"]["tmp_name"],
      "entrys/" . $_FILES["file"]["name"]);
      echo "Stored in: " . "entrys/" . $_FILES["file"]["type"];
      }
    }
  }
else
  {
  echo "Invalid file".$_FILES["file"]["name"];
  }
}

 

but i still get invalied file... wont it prosses it due to it being within the form even if it has nothing in it...i would have thought u had to see if it was blank and if so dont do it

[runnerjp]

Ok i just thought when i was typing it i answered me own question but would this be ok if (!$_FILES['file']["name"]== '')

Ah yeah my mistake. Seems it still passes the $_FILES array but the 'error' property is set to 4; meaning 'no file was uploaded'.

 

You could use:

 

if ($_FILES['file']['error'] != 4) {
