Populate image field

one of the more powerful plugins within the WordPress repository is something called advanced custom fields by Elliott Cottam right now you're looking at the advanced custom fields website which is dedicated to the documentation and support of this plug-in it's a great plugin very extensive documentation and there's lots of rich information that can be gained here for the sake of this particular demonstration we're going to focus upon one specific type of field which is the image field and before doing that were to jump over to the WordPress admin nothing the WordPress admin I've gone ahead and just gone over to a post page just show you guys what exactly a post looks like out of the box so out of the box you have two fields a title field and a content field these reflect the two main pieces of herbal content within the out-of-the-box WordPress database table and content now it's not uncommon that for many projects you might want to add additional pieces of information to the UI such as images or you know tertiary content or any number of additional things against the saiga cementation we talked about an image if we want to add an additional image field down here so that we could you know attach an image to a specific place than the UI how do we go about doing that the way we're installed this has been using advanced custom fields so you may notice within the dashboard we also have section over here called custom fields so I'm going to go ahead and click into there this is where we can manage your field groups and click to add a new field group I'm gonna call this test I'm gonna add a field this feels me called super-sweet image and oh so this is the title this is what will physically display about the field and this is the slug which is what will actually a record in the database this is the key that will associate the value that's set when a user creates a piece of content that has a utilize of this field under field type I'm going to go ahead and choose image and a bunch of additional options appear the value that you'd like to return this is what will happen when you use advanced custom fields and get or the field functions you can choose between an array of data a URL or an ID more often than not you'll probably want an array or a URL you rows kind of a shortcut arrays got a little bit more meaningful and robust in terms of what you get back either these is totally fine parade I'm gonna click URL you can choose a preview side of this again only affects what you see in the admin so whether you want to be a small medium large thumbnail size more often off in the atom you don't want to clutter it with too bit large of a photo so for right now leave it at a thumbnail you also have the option of going ahead and restricting the size of the image through either the minimum or maximum dimensions this is just a way of further tailoring the content and helping to make sure that the content authors later are uploading to create the correct type of data same with the the allowed file types custom control logic is something that's a little bit more advanced and can be covered at a different time alright so there's my field I'm gonna go ahead and collapse that and then the next part location what what part of the admin UI do we want to show this new field group that we're making here I remember this is one field super sweet image but the test right here is the entire group so there could be any number of groups any number of items within a group so right now we're gonna say we want to assign a face on the post type and we want to the post a be equal to and right now within our implementation of WordPress we only have two registered content types post types posts and pages the ones are out of the box if you had extended this to include additional custom post types those would appear as list as well so if we're right now we're gonna say that we're going to augment our posts with this new super sweet image down here under settings you're able to control where this particular field group appears on the post page right so we can choose if we want to be a standard meta box this is just talking about what the field group looks like when it's wrapped in a little box or not you talked about the position where how high up on the page you wanted to fall this this order number in conjunction with the position control exactly where it falls on the page so if right now we'll just keep it very basic we'll create a field group called test we'll put one field in it and we will say that this is gonna be associated with post types of posts and I go ahead and publish this take some loss thinking and I'ma return to my have over here that has my new post notice out of the box were repressed two fields I go ahead and reload this page to create my new post Eunice and now I have a new meta box it has the label of test and this is a place I can add my super street image I can go ahead and click pick anything I want from within my my library in this case I'll pick now just a graphic select and there it is I go ahead and publish this article now say a test post some content you publish and there you have it that's how you go ahead and create a new field using advanced custom fields you you
