Quick question

[harkly]

I have a checkbox and I want to verify that it is or is not checked.
Right now I only get 1 answer regardless if the checkbox is checked or not.

if (empty($delete_3))
  {
    echo " Not Deleting 3 ";
  }
else
  {
    echo " Going to delete 3 ";
  }

I've been trying different code for the if statement and not really sure what I should use.

Is this a valid statement??

if ($delete_3 != 'Null')

This is my form code

<input type='checkbox' name='delete_3'>Select to Delete image

There are 5 different checkboxes on the same from 1-5, could this be a problem?

Here you can try and see all the values posted.
Inside the $_POST array

The value of checkbox would be in: $_POST['delete_3']

<?php

if(isset($_POST['submit'])){

echo '<pre>';
var_dump($_POST);
echo '</pre><br />';

}

?>
<form method="post">
<input type="checkbox" name="delete_3">Select to Delete image<br />
<input type="submit" name="submit">
</form>

Thanks will try that!

Is it possible to verify that an image/file has been selected?

With the following code only the Delete part works, it echos out the same message no matter what I do to the other part, elseif

<?php

  include('library/login.php');
  login();
  mysql_select_db('test');

$userID="test";

$photo_3=$_POST["photo_3"];
$delete_3=$_POST["delete_3"];


if(isset($_POST['delete_3']))
  {
    echo "Deleting";
  }
elseif ($photo_3 != 'null')
 {
    echo "Change photo";
 }
else 
  {
    echo " Do nothing";
  }

?>

My altimate goal is to be able to Delete, add/change or do nothing to an image. I have my delete & add/change code working now just need to combine them.

Is the photo_3 form element a checkbox? If so, do the same type of if() statement as you do for the delete checkbox then.

Also note that this code probably doesn't do what you intended it to do:

elseif ($photo_3 != 'null')

Here, you're checking if $photo_e is equal to the word "null" - not to be confused with a null value, e.g.:

elseif ($photo_3 != null)

[harkly]

The photo_3 is an image that is being uploaded to the server.

Thanks for the clarification of null vs. "null"!!!!! Very very helpful!

By "being uploaded" do you mean this is a file upload from a form? If so, you're not going to find it in the $_POST array - see this manual page for more info: [man]features.file-upload[/man].

[harkly]

You are correct. I am uploading a file from a form. I am using the
COLOR="Indigo"; [/COLOR] but was trying to set up a catch all to see why things don't work when I combine them.

I just don't know how to make it acknowledge that a file has been selected, so it can then process it - this is only in this if statement. I have the individual code for uploading and renaming my image file working as well as the deleting file code.

You should give the checkbox a value attribute; that way it will have something to submit.

Another thing: if you have several of these images to work with, a better way of naming the fields would be "photo[5]", "delete[3]", etc.

Then instead of writing the same code half a dozen times with only tiny (easily missed) differences between them, you can write it once and run it several times.

for($i=1; $i<=5; $i++)
{
    $photo = $_FILES['photo'][$i];
    $photo_real_name = $photo['name'];
    if(!empty($_POST['delete'][$i]))
    {
        //...
    }
}

Thanks for your posting. Are you interested in Party, weekend, barbecue, cooking, grilling?
