Upload Image

Ok. Seems that there is no answer from your team.

I was hoping to learn what GF uses to hook in to the wordpress attachement for images as I could then use that to run a comparison and then delete the attachements.

Ok. How bout this...

the following deletes the old image (handled from a form) and the next step is to upload the new one.

//if image field has data
	 if(!empty($_FILES))
	 {
	  $filename = $_FILES['image']['name'];
	  echo $filename;
	  if($images = get_children(array(
		'post_parent'    => get_the_ID(),
		'post_type'      => 'attachment',
		'numberposts'    => 1, // show one
		'post_status'    => null,
		'post_mime_type' => 'image',
	     )))
	  {
		foreach($images as $image) {
		$img_ID = $image->ID;
		break;
		}
	  }
	 wp_delete_attachment( $img_ID, $force_delete = true ); //delete old images

How can I hook into WP or GF to upload a new one? --Keep in mind that GF upload image already does this somehow...it's the 'How I am looking for.

by the way - I couldn't work a smaller approach to getting the attachment ID then running a foreach.

Nevermind. I found the solution in a rather obscure place that has nothing to do with GF - the wordpress core media.php.

Pastie is down and my antvirus hates the other link so don't you yell at me!

I'm terrible at writing plugins, so maybe someone else can make a profit from this. (like the guys at GF, perhaps..)

Kevin, you always have technical and knowledgable answers so feel free to ask me questions. This is a section of code (fully functional) which deletes the old post image and adds the newly uploaded one. I've added a file path variable for file handling of documents related to the post for the extended script.

As you are aware I'm building a jobs based website so, essentially a mild form of a membership site. Uploading and downloading profile/company images is a good feature to have, as well as resumes. It would be very easy to allow modification for a user based document sharing site, or many other ideas.

//If we submitted the form
if(isset($_POST['submit']))
{
     array_pop($_POST); //remove the submit button as post data from array
	 $post_id = $_POST['post_id']; //get the id of the post
	 unset($_POST['post_id']); //lets not add the hidden post_id field
	 //the directory path to upload the files to
	 $uploaddir = ABSPATH . 'wp-content/uploads/post-' . $post_id . '/';

	 //if image field has data
	 if(!empty($_FILES))
	 {
	  $filename = $_FILES['image']['name'];

	  wp_mkdir_p( $uploaddir );//check if the directory exists and create one if it doesn't

	//delete attached image
	  if($images = get_children(array(
		'post_parent'    => $post_id,
		'post_type'      => 'attachment',
		'numberposts'    => 1, // show one
		'post_status'    => null,
		'post_mime_type' => 'image',
	     )))
	  {
		foreach($images as $image) {
		$img_ID = $image->ID;
		break;
		}
	  }
	 wp_delete_attachment( $img_ID, $force_delete = false ); //delete old images

	 //Upload new image
	 require_once(ABSPATH . 'wp-admin/includes/admin.php');  //include this !IMPORTANT
     media_handle_upload('async-upload', $post_id); //use WP media handler to upload the file 

	}

	 //update the fields
	 foreach($_POST as $key => $value)
	 {

         update_post_meta($post_id, $key, $value);

     }
}

Yep.
"c'mon, guys. I figured I'd trade code for code. Is that not a fair deal, here?"

It's true that humor doesn't always translate well in text format.

Frankly, one of the developers left a sour taste shortly after joining/buying the product and I've been trying to forget about it. It's that whole 'first impression' thing and the rudeness lingers in the back of my mind and reflects in my writing.

For the reflection in my writing I do apologize and will make attempts to edit a wee bit better.

Regarding the rude first impression..it may well have been an interpretation akin to the one you took with the
"c'mon, guys. I figured I'd trade code for code. Is that not a fair deal, here?"

A simple miscommunication.
