Caldera Add Alt to Uploaded Images Front End

It's not very hidden… I'g a huge fan of "FEATT" (front end all the things). Yes, that's an acronym I merely fabricated upward right at present, but I might but continue to use information technology. I love building websites that go on the users on the front end cease for posting & editing new posts, editing profiles, and more. Sometimes that's not feasible for the blazon of site you're working on, but many times information technology is, peculiarly with some of the tools available at present that make things easier for the states to setup. Enter Caldera Forms.

This tutorial walks you through a clean (and safe) setup for front terminate posting and editing with a Caldera Class.

Before getting into the details, let me mention some of the limitations of Caldera Forms that I've come up across in working with front posting and editing. At the fourth dimension of writing this mail Caldera Forms is at version ane.three.02 and the Caldera Custom Fields improver is at ii.0.three.

The electric current limitations

No WYSIWYG Editor – This is kind of a large ane. This means that the postal service content you are posting/editing will only have a text area field. No TinyMCE with image upload. No simple method for bold, italic, headings,etc. I'chiliad sure this may go added in the hereafter, only for now it's not available. I saw somewhere that a WYSIWYG field improver was made, on Github, simply not fully tested. I'one thousand not comfortable using information technology on a production site so I didn't examination it for this write up.

No Featured Prototype when editing a post – The current implementation for front end posting and adding a featured image is pretty smooth. It works great. The effect is when editing a postal service yous don't see the currently uploaded featured paradigm in the file upload field. That means you accept to reset it each time you edit the mail service. Not fun. In that location's a nice filter to add the current featured image as the default for the field, but even doing this won't testify the actual image, only the file name in the field.

Taxonomies/Categories/Tags – There's very limited native back up for taxonomies when posting/editing posts in Caldera Forms. Information technology's easy to auto-populate a field with term names, merely it requires lots of extra piece of work/code to relieve the terms, peculiarly when trying to employ the same class for new posts and editing existing posts.

The fun part – Let's Build A Grade!

Brand certain you have Caldera Forms and Caldera Custom Fields installed.

Let's create a simple course with 4 total elements.

1. Title – Unmarried Line Text field
2. Content – Paragraph Text field
3. Save – Submit push field
4. Editing Post ID – Hidden field to $_GET the post ID we want to edit

The first 3 are pretty obvious, I'll leave them to y'all. The hidden field is catchy. Nosotros're going to be adding a link on each existing post that adds a link to the edit post form with a query arg that includes the mail ID. This is pretty bones, only nosotros need some custom code (custom shortcode) that does some safety checks to make sure the logged in user is the author of the post they are trying to edit.

Form Processors

Just over to the Processors tab in Caldera Forms.

Save as Post Type processor

1. Click the "Add Processor" push button and choose "Custom Fields: Save every bit Post Type"
2. Set your mail service type and post condition (publish, draft, {custom condition here}, etc)
3. Set Post ID to "{get:post_id}" without the quotes
4. Ready your Title/Content fields

The {go:*} magic tag allows Caldera Forms to use a specific query arg value to process the form. Our code later on will add together the post_id query arg/value for the grade to process.

Redirect processor

1. Click the "Add Processor" button and choose "Redirect"
2. Set URL to "{post_type:permalink}" without the quotes
3. Set Redirect Message to whatsoever you desire. Nosotros won't be using this here since we're not going to salvage with Ajax

At this indicate, it may be smart to save the class if you haven't already. 😉

Form Full general Settings

At the top of the Caldera form dashboard, let'south edit the General Settings. The well-nigh important settings here are making certain we don't save via Ajax and making sure we're not saving (grade) entries.

1. Name the form "Edit Post". You lot can modify this, just y'all'll take to alter the code below with your new name.
2. Set "Capture Entries" to "Disabled"
3. Make sure "Ajax Submissions" is unchecked. We want to force a page reload later saving so our redirect processor fires during that process. It volition work with Ajax, just you'll get an unnecessary flash on the page subsequently ajax is done processing. This is not necessary since volition exist redirecting/reloading a page anyway.

Even More Fun – Let'south Lawmaking

First, create a WordPress page called "Edit Postal service". You lot can change the proper noun later, merely you'll have to alter the code below as well.

Custom Shortcode

Nosotros need to write some code to make the experience much smoother and safer.

Let's create a shortcode to brandish the course. We could just use the Caldera shortcode, just we want to exercise some custom checking to make certain the currently logged in user is the author of the mail service they are trying to edit.

This following lawmaking creates an [edit_post] shortcode we tin can put on any page.

Custom 'Edit Mail' link(s)

I'yard giving you 2 different options for adding these front end edit post links. The commencement is a standalone link before the post content, the second is a filter on the native WordPress edit link. They both work fine, information technology'southward just a preference which you like improve.

Standalone Edit Post link

I started with a nice helper role to check if the currently logged in user is the author of the post we're trying to edit.

Now, our filter on the_content to brandish the edit post link earlier our content mail's content.

This filter adds a custom 'Edit Mail' link on posts the logged in user has authored. The link also adds ?post_id=123 query arg to the end of the /edit-mail/ page URL. This is the mail ID that allows the class to know which post to edit.

I too fabricated this function actually piece of cake to add your own custom post types as well. If your course is meant to edit a custom post type, just use that post type name in place of the ones in the current array below.

WordPress Edit Post link filter

This filter adds the aforementioned link as the to a higher place code, but uses the default WP edit posts link (displayed in unlike locations in unlike themes, if displayed at all). This filter besides alters the WP toolbar Edit Post link.

Once you decide on one of these methods, you will see a link on athenaeum and single posts for the postal service types y'all've set up.

Add shortcode to your page

The concluding step is to add our custom [edit_post] shortcode to the 'Edit Post' page.

That's it, edit your posts on the front end!

That'south all in that location is besides it. Authors will at present be able to edit their posts on the front stop, and access will be restricted if they attempt to edit other posts, or if a none author tries to practise annihilation tricky.

Let me know in the comments how it works for yous…
