accept multiple

[bluewalrus]

I'm trying to make this accept multiple inputs but its only working with one right now. I added 2 more input fields but it ignores them. Any ideas? Thanks for looking and any suggestion.

<?php
//define a maxim size for the uploaded images in Kb
 define ("MAX_SIZE","9000000"); 

//This function reads the extension of the file. It is used to determine if the file  is an image by checking the extension.
 function getExtension($str) {
         $i = strrpos($str,".");
         if (!$i) { return ""; }
         $l = strlen($str) - $i;
         $ext = substr($str,$i+1,$l);
         return $ext;
 }

//This variable is used as a flag. The value is initialized with 0 (meaning no error  found)  
//and it will be changed to 1 if an errro occures.  
//If the error occures the file will not be uploaded.
 $errors=0;
//checks if the form has been submitted
 if(isset($_POST['Submit'])) 
 {
     //reads the name of the file the user submitted for uploading
     $image=$_FILES['image']['name'];
     //if it is not empty
     if ($image) 
     {
     //get the original name of the file from the clients machine
         $filename = stripslashes($_FILES['image']['name']);
     //get the extension of the file in a lower case format
          $extension = getExtension($filename);
         $extension = strtolower($extension);
     //if it is not a known extension, we will suppose it is an error and will not  upload the file,  
    //otherwise we will do more tests
 if (($extension != "jpg") && ($extension != "jpeg") && ($extension != "png") && ($extension != "gif")) 
         {
        //print error message
             echo '<h1>Unknown extension!</h1>';
             $errors=1;
         }
         else
         {
//get the size of the image in bytes
 //$_FILES['image']['tmp_name'] is the temporary filename of the file
 //in which the uploaded file was stored on the server
 $size=filesize($_FILES['image']['tmp_name']);

//compare the size with the maxim size we defined and print error if bigger
if ($size > MAX_SIZE*1024)
{
    echo '<h1>You have exceeded the size limit!</h1>';
    $errors=1;
}

//we will give an unique name, for example the time in unix time format
$image_name=$image;
//the new name will be containing the full path where will be stored (images folder)
$newname="images/".$image_name;
//we verify if the image has been uploaded, and print error instead
$copied = copy($_FILES['image']['tmp_name'], $newname);
if (!$copied) 
{
    echo '<h1>Copy unsuccessfull!</h1>';
    $errors=1;
}}}}

//If no errors registred, print the success message
 if(isset($_POST['Submit']) && !$errors) 
 {
     echo "<h1>File Uploaded Successfully! Upload Another?</h1>";
 }
 ?>
 <!--next comes the form, you must set the enctype to "multipart/frm-data" and use an input type "file" -->
 <form name="newad" method="post" enctype="multipart/form-data"  action="">
 <table>
     <tr><td><input type="file" name="image"></td></tr>
        <tr><td><input type="file" name="image"></td></tr>
            <tr><td><input type="file" name="image"></td></tr>
     <tr><td><input name="Submit" type="submit" value="Upload image"></td></tr>
 </table>    
 </form>

Change each input to this:

<input type="file" name="image[]">

Then access them as an array:

for($i = 0; $i < count($_FILES['image']); $i++){
    $image = $_FILES['image'][$i];
    //Handle $image.
}

or

foreach($_FILES['image'] as $image){
    //Handle $image.
}

oo ok thanks so the [] automatically keeps track of how many there are?

and i end the for at the end of the code for 1 image right?

Yes. [] is a PHP construct; see Arrays.

But I don't understand your second question... EDIT: Oh, yes: You only handle one image at a time inside the loop.
