Display Custom Taxonomy Name As A Shortcode
On my WordPress site I have created a custom taxonomy named "game" which lists different gaming titles. I want to be able to display the names of these titles on my posts using a shortcode.
Prior to creating a custom taxonomy, I was using WordPress' default categories taxonomy, and had the following code (found on stack exchange) working well:
function shortcode_post_category () {
$html = '';
$categories = get_the_category();
foreach( $categories as $category ){
$html .= '<h2>' . strtoupper($category->name) . ' KEYBINDS</h2>';
}
return $html;
}
add_shortcode( 'category-keybinds', 'shortcode_post_category' );
From what I understand I need to change the `get_the_categories` to `get_the_term`(?) however with my very limited knowledge of `php` I cannot seem to get this to work on the new "game" taxonomy. | If you look at the source code of `get_the_category()` you see that this is not much more than a call to `get_the_terms ( $id, 'category' )`, where `$id` is the current post id.
So, what you need is `get_the_terms ( get_the_ID(), 'game' )`. You need `get_the_ID`, because the `ID` is not passed to the shortcode as it is to `get_the_category`. | stackexchange-wordpress | {

include specific Pages to wp_list_pages with filter
How can i make a simple filter to display only specific pages ( **include instead of exclude** ) as an output to wordpress pages widget?
I made this code , but its not working
function specific_pages($output) {
$args = array(
'include' => array(147,12,32),
);
$output = get_posts($args);
return $output;
}

Permalink slug no longer editable when using post_type_link filter
I want to customize the output of the permalink for a custom post type, but I want the permalink to still be editable when editing a post. I'm using the `post_type_link` filter:
add_filter( 'post_type_link', function( $post_link, $post, $leavename, $sample ) {
if ( 'job' == $post->post_type ) {
$post_link = ' . $post->post_name . '/';
}
return $post_link;
}, 10, 4 );
When this filter is active, it no longer shows the "Edit" button next to the permalink when editing the post. Even if I remove the custom permalink stuff and only have `return $post_link;` it still disables editing of the permalink.
How can I customize the output and still keep the permalink editable? | > How can I customize the output and still keep the permalink editable?
The following worked for me:
$post_link = home_url( '/job/' . ( $leavename ? '%postname%' : $post->post_name ) . '/' );
I.e. If the `$leavename` is `true`, use `%postname%` in the URL. Otherwise, you may then use the actual post name/slug, i.e. the value of the `$post->post_name`.
Additionally, I suggest you to use `home_url()` than hard-coding the site URL into the permalink. :)
And I presume you will or have already setup the rewrite rules for the permalinks (`/job/<post slug>/` in the above example)?
> Even if I remove the custom permalink stuff and only have `return $post_link;` it still disables editing of the permalink.
I'm not getting that issue, so it's probably a theme/plugin conflict on your site -- try deactivating plugins and enable them back one at a time until you've found the culprit. | stackexchange-wordpress | {

get_results not returning anything
What is the basic way to use $wpdb and get_results?
This is my code:
global $wpdb;
$q="SELECT * FROM wp_usermeta WHERE meta_key = 'nickname' AND user_id = 771";
$result = $wpdb->get_results($q);
echo $result;
The query string is good because I can run it in phpmyadmin and it works fine. I am not getting anything back when run through page. | `$wpdb->get_results()` returns an array on success, so you can't simply `echo $result;`.
Instead, you can use `foreach` to loop through the results and display whatever the data that you want to display:
$results = $wpdb->get_results( $q );
foreach ( $results as $row ) {
echo $row->meta_value . '<br />';
}
But I can see that you're trying to select just _one row_ , so you'd want to use `$wpdb->get_row()` and not `$wpdb->get_results()`:
$row = $wpdb->get_row( $q );
if ( $row ) {
echo $row->meta_value;
}
But then again -- because `wp_usermeta` is the default table for WordPress users' meta, if you just want to retrieve the meta value, then there's a function you can (and should better) use -- `get_user_meta()`:
echo get_user_meta( 771, 'nickname', true ); | stackexchange-wordpress | {

edit_tag_form_fields is depricated but tag_edit_form_fields doesn't work
I need to create, retrieve, update and display a custom field in Wordpress tags. This code works for displaying the custom field, but its deprecated.
function tag_edit_form_fields ( $term ) {
?>
<tr class="form-field">
<th scope="row"><label for="term-colorpicker">Custom Field: </label></th>
<td>
<input type="custom_field" name="_custom_field" value=" <?php echo $custom_value; ?>" id="term-custom_term" />
<p class="description">This is a custom field.</p>
</td>
</tr>
<?php
}
add_action('edit_tag_form_fields','tag_edit_form_fields');
Using the **new** function `{$taxonomy}_edit_form_fields` as `tag_edit_form_fields` doesn't seem to work. | While adding the tags to this stack exchange question, I added `tags` and the hint showed up as `post_tag`.

Does a single theme license work on multisite?
I am trying to create a multisite network and I want all of the sites in that network to look similar. So, I am planning to install a single premium theme in the whole network. My question is, will the same license work for all the sites in the network or will I have to purchase individual license? | That depends upon the seller of the theme. Contact them if their license is not clear about this. I ran across a couple of sellers of plugins (not sure about their themes) that have a special license specifically for multisite networks, while others say that if the sites are related in use (say one business' main site and the same business' blog site), you only need one license but if the sites are for different businesses, you need a license for each site. Whether the sites have their own domain names rather than just subdomain names can make a difference too. | stackexchange-wordpress | {

Count how many posts have a specified tag AND category
I know how to count how many posts has a certain tag, or category
For example:
$term_slug = 'some-post-tag';
$term = get_term_by('slug', $term_slug, $post_tag);

I want to count how many posts that have the tag(slug) _"cat"_ and the category slug _"allowpost"_
Is this even possible?
Edit: if possible, it would be good if this is manageable via some solution similarly my first script, because this is going to be used on search result pages, and **_different post pages_** , so adding something to the loop itself won't work.. | This solved my issue, originally created by Mr. Prashant Singh @ WordPress forum
$args = array(
'posts_per_page' => -1,

Escaping crashes my output
When I add wordpress escaping code like esc_attr_e to below variable, it writes text instead of html code to my browser:
<?php echo esc_attr_e( $redux_demo['editor-text-header-left'], 'hekim' ); ?>
when I remove the escaping code, the variable gives html code.
now, it gives the below text:
<a href="#"><i class="fa fa-medkit text-thm2"></i> Help | </a><a href="#">Forum | </a><a href="#">Skype | </a><a href="#">Mon - Sat 9.00 - 19.00</a>
How can I escape it correctly? | There are several issues here:
1. `echo esc_attr_e` should be just `esc_attr_e`, the `_e` means it already echo's
2. `esc_attr_e` is not just an escaping function, it's a localisation API, it's shorthand for `echo esc_attr( __(`
3. `esc_attr` strips out HTML, it's intended for use inside HTML attributes where HTML tags are not allowed.
4. You must never pass variables and dynamic values into localisation functions
If you want to escape a string that contains basic HTML such as paragraphs etc, use `wp_kses_post`, e.g.:
echo wp_kses_post( $redux_demo['editor-text-header-left'] ); | stackexchange-wordpress | {

Delete post meta by serialized meta value
I have some post meta entries which I like to delete from the database. The delete_post_meta() function seems the way to go:
delete_post_meta( int $post_id, string $meta_key, mixed $meta_value = '' )
The problem: I have many entries with the same meta_key, so I'd like to specify the rows to be deleted by meta_value. But, the meta_value is serialized data. So how do I use `delete_post_meta()` to delete the post_meta by a specific value of the specialized data?
For example, the serialized data:
a:6:{s:2:"id";s:1:"1";s:4:"name";s:3:"PM1";s:5:"email";s:19:"[email protected]";s:3:"url";s:24:"
How do I delete by serialized ID value? | Try below code to delete the post_meta by a specific value of the specialized data:
$args = array(
'post_type' => 'post',
'meta_key' => 'any-meta-key',
'posts_per_page' => -1
);
$query = new WP_Query( $args );
if($query->have_posts()){
while($query->have_posts()){
$query->the_post();
$get_ID = get_post_meta($post->ID, 'any-meta-key', true);
// Change the id value that you want to delete
if ( !empty($get_ID['id']) && $get_ID['id'] == '1' ) {
delete_post_meta($post->ID,'any-meta-key',$get_ID);
}

Why does Wordpress uses HTTPS for JS, CSS on EC2

All Titles and Menus changed to "CHILD THEME LOADED"
I'm testing out a theme update on our website using a staged site created by WPStaging. That part seemed to work well.

if ( $_POST['gender'] != 'Male' || $_POST['gender'] != 'Female' ) {
echo 'sorry it must be either male or female'; return '';
}
} | The reason it does not work is due to a logic error, which becomes obvious if you follow the code manually for each value It has nothing to do with the `select` element, or special behaviour of `!` or `!=`
So lets look at your conditional:
$_POST['gender'] != 'Male' || $_POST['gender'] != 'Female'
* if ( gender is not male ) OR ( gender is not female )
* then complain it must be male/female
So lets say that the gender is male:
* if ( false ) OR ( true )
* then complain it must be male/female
Since true is true, it resolves to `if true` and the complaint appears.
So it appears, the problem is a misunderstanding of how `OR` works
`a OR b` <\- this resolve to true if either 'a', 'b', or both a and b are true.
What I think you meant was:
`if ( gender is male OR gender is female ) is not true`
rather than
`if ( gender is not male ) OR ( gender is not female )`

how to change site tag line for particular pages
I need to change my site tag line. Basically, this is school site we create for xyz higher sec school and ABC Nursery school; so I need to add both as a tag line in my site if I use xyz higher sec school I can't be able to use ABC NURSERY for those particular pages.
I need to change tagline for around only 6 pages; kindly suggest me for that. | If your theme is using the WordPress site tagline, you should be able to filter it. `get_bloginfo( 'description' )` will call `get_option( 'blogdescription' );`, and we can filter the value of an option using the `option_{$option}` hook.
Let's suppose, for this code sample, that you want to change the tagline on 3 pages, with the titles **Kindergarten** , **Nursery School** , and **Babysitting**.
add_filter( 'option_blogdescription', 'wpse368031_change_tagline' );
function wpse368031_change_tagline( $tagline ) {
$pages = array( 'Kindergarten', 'Nursery School', 'Babysitting' );
if ( is_page( $pages ) ) {
$tagline = 'ABC Nursery';
}
return $tagline;
}

Order All Pages table in administration
In administration, in the "All Pages" section, each time I add a new page the table is refreshed order by page Title. I reorder the table clicking on "Date" column to keep working on the last updated pages, but every refresh the order change again to Title.

Staging Sites: What to push through?
I have a staging site where I am improving the theme and layout, adding a couple of plugins to add a slide in navigation bar etc. The issue is that on the live site, people are signing and purchasing membership, plus some memberships are expiring etc. Oh and I'm with siteground.
My question is, how do I push through my staging site so that the users' data on the live site persist? Is all user data stored in the same table? When pushing the new site is it possible to only push through the database tables that I have made changes to due to my development, leaving all other tables in tact from the live site? | Siteground should be able to tell you if your sites share a DB (or it should be evident from whatever control panel they provide).

What is the use of $content_width?
In the requirements of Envato I saw that they require a `$content_width` to be set. I searched for it on the internet but can't really understand why?
I don't use it and the theme is responsive.
If I only declare the `$content_width` and never use it, what value should I give it? | `$content_width` is used to set the default width of embeds, for situations when an element needed to specify a width. This is how WP knew the width of the main content area.
However, this was back before the push for responsive design, and modern CSS with fluid embeds and responsive breakpoints. So it isn't needed much but it can still result in odd embeds if you set a bad value. Content width sometimes gets used in other edge cases too, but that was the main use case and its reason for being.
So I suggest:
* Figure out the content width on the most common desktop resolution, and use it to set `$content_width` in `functions.php`
* Then, apply CSS to adjust embeds responsively/fluidly as you would normally do | stackexchange-wordpress | {

Wordpress 404 all pages except home
I know this question might be a repeat or duplicate of another post. I've been getting this error after shortly migrating the domain from `http` to `https`.
I've been following multiple questions and answers like this one right here but none of them seem to work.
Solutions i've tried: -> disable all plugins and enable them again -> change `.htaccess` file to the default wordpress -> change permalink structure to the default one again.

The problem does not happen if i use the default permalink structure and if use the following code in the wp-config:

define('WP_SITEURL', '
//define('WP_DEBUG', true);
define('CONCATENATE_SCRIPTS', false); | Fixed it by changing the website url in the database on the table `wp_options`

Can Wordpress admin user + database credentials be used to gain Cpanel or FTP access?

* use a different prefix for your database
* create strong credentials for your hosting place
* create strong credentials for FTP users (and only use SFTP)
* remove features (plugins/themes) that you are not using
* keep everything updates: WP, themes, plugins, PHP
* use PHP version 7.x+
* regular backups - off-host
* htaccess security
* disable RPC

Plugin to allow for recurrent subscription + exclusive content

Wrong Canonical url link

* I have switched of Yoast > doesn't help
* I switched on Yoast again - and explicitely changed the canonical link in the Yoast SEO section of th page > that solves it.

If you install the Yoast Test Helper Plugin, you can go to Tools > Yoast Test. In the "Yoast SEO" box with a bunch of buttons, use the "Reset Indexables tables & migrations" button to flush them. You can then uninstall the plugin, remove your manually-entered canonical URL, and the default (autogenerated) canonical URL will be fixed.

In the media Rest API, what is "missing_image_sizes"?
I'm trying to understand the media rest-API. The last item in the schema:
 _a private field_ in the REST API and the value is one or more image sizes as returned by `wp_get_registered_image_subsizes()`.
And the function which is used with that field is `wp_get_missing_image_subsizes()` which returns:
> _(array)_ An array of the image sub-sizes that are currently defined but don't exist for this image.
So for example, if you added a new image to your library and then — after the image's thumbnail and other custom sizes are generated — you programmatically called `add_image_size()`, then you'd likely see the `missing_image_sizes` field containing the newly added image size when you request the image data through the REST API.

Change password notification email

How to not cache nonces with WP Rocket?
We have a system where we pass a nonce from a PHP-script on the server to an AJAX-call running client-side, and then back again to check the validity of the request.
This nonce is cached, and we can't figure out how to exclude it. We had cache time set to 10 hours but have since reduced it to 8 hours.
But let's say the nonce is renewed at 12 AM and the cache is renewed at 10 AM, we still have six hours of the nonce not working even with 8 hours cache.
How do we fix this? | Find the specific AJAX call URL and prevent that being cached with the WP-Rocket advanced rules settings. <
As per your comment, you need a strategy for not having the nonce in a file that can be cached such as javascript files, so as you said, use PHP to generate the nonce and pass it outside of the javascript file.

file_get_contents | escaping doesnt show the page
I have below code.`echo $FileContents;`shows the page which comes the php variable correctly, but the escape function which is `<?php esc_html( $FileContents ); ?>`didnt show anything.
How can I escape it correctly and show the page?
<?php global $redux_demo; ?>
<div class="row">
<div class="col-md-12 ulockd-mrgn1210">
<?php $FileContents = file_get_contents($redux_demo['text-location-service-details']); ?>

## Update
If you actually want to filter the list of allowed HTML tags in the variable's value, then you can use the WordPress' KSES functions like `wp_kses_post()` and `wp_kses_data()`:

is MariaDB error related to Automatically add new top-level pages

How to programatically toggle the media setting "Organize my uploads into month- and year-based folders"?

// 1 to enable the "checked" state
update_option( 'uploads_use_yearmonth_folders', 1 );
You can also use a filter hook such as `option_<name>`:

Setting 'autoload' to 'no' with Settings API

Is there any way to achieve this using the Setttings API? Asking because I have many DB table `options` entries that were created using `register_setting` and all of the `options` have `autoload` set to `yes`.
I need to optimize this because hundreds of entries are being loaded on every page load unecessarily. | The only way to accomplish this is to add the option to the database yourself before the Settings API does so. To do this, add a 'sanitize_callback' to the register_settings function:

How to remove author name and link from a shared link preview?

How to get the revisions feature back on the classic editor?
Any of the recent Wordpress updates have removed the revision option from the classic editor. It runs in the background and saves the regions but no way to access it on the classic editor. Gutenburg has and supports the revision option well. But I don't use Gutenburg.
I don't know when they removed the feature, but I only realized today. How can I get the feature back on my Classic editor?
I checked my database, I have the revisions, even for new posts, and I also checked by enabling the Block editor.
;
This filter disables the Gutenberg sitewide but it doesn't work smoothly in other custom-post-types. Not only the revisions but other features are also hidden on the post edit screen of custom-post-types.

WordPress Theme With Modified View
I'm very new to WordPress. I'm going through some tutorials in developing a theme. What I'm trying to grasp is creating a theme when the pages are a bit different. They all have the same theme but the layout is different for example on the home page and the rest of the pages.
For an example of a home page:
![enter image description here](
And for all the content pages the look is somewhat different:
![enter image description here](
I'm looking at the hierarchy and I see home.php and page.php, but I'm not 100% sure how they tie in.
Any advice or links to better understand how this works would be appreciated | Sometimes the names can be misleading as home.php actually refers to the page that stores all of your blog posts.
In general, use either page-home.php or front-page.php for the home page and then page.php for the rest. Whenever you have a specific page with a different layout, you can create a new template that is styled specifically for that. Eg. page-contact for a contact page that doesn't follow the styles of other pages. The page-XXXXX.php is dependent on the slug of the page so that is how WordPress finds it. | stackexchange-wordpress | {

Hide author info in single posts by certain users

Thanks, | No, there's no need to use `wp_set_current_user()`.
> I was wondering how to fire `wp_head` action if single post by certain users (either by user ID or username)?
You can use `$post->post_author` to get the ID of the author of the post, and put the user ID list in an array, then just do `in_array()` to check if the author ID is in the ID list. For example:
function hide_author() {
//global $post; // Instead of this,
$post = get_post(); // I would use this one.
// Define the user ID list.
$user_ids = array( 1, 2, 3 );
if (
$post && is_single( $post->ID ) &&
in_array( $post->post_author, $user_ids )
) {
?>
Your code here.
<?php
}
}

Put post ID on the custom post type URL

'hierarchical' => false,
'rewrite' => array('slug' => 'sa', 'with_front'=>false ),
---
---
---
);
register_post_type( 'ex_article', $args );
}
On permalink setting, I use `Post Name : mysite.com/sample-post/`. Using a custom structure is not an option for me, I need to avoid it, and also it does nothing to custom post type. | It's quite easy, actually:
1. Change the generated permalink structure so that it ends with the post ID and not the post slug (but it still contains the post slug):
// After you registered the post type:
register_post_type( 'ex_article', $args );
// .. run this code:
global $wp_rewrite;
$wp_rewrite->extra_permastructs['ex_article']['struct'] = 'sa/%ex_article%/%post_id%';
2. Then replace the post ID placeholder (`%post_id%`) in the generated permalink URL with the correct post ID:
add_filter( 'post_type_link', function ( $post_link, $post ) {
if ( $post && 'ex_article' === $post->post_type ) {
return str_replace( '%post_id%', $post->ID, $post_link );
}
return $post_link;
}, 10, 2 );

Can you Recover a Wordpress User from a Backup
so basically i deleted a wordpress user, and with that user, the settings, media and many pages were deleted. is there a way to restore only that user, because he has been inactive for about a year, and the last backup is about one year ago. | I just did a test on Wordpress 5.4.2.

So, you may find that you can recover the posts/pages from the trash, however if they've been deleted from the trash they might be gone permanently.
You can always recover data from backups manually, however it would be quite a manual process to find the data from the backup and re-inserting it into the database manually, or re-entering it through the WP dashboard.
For more help see if you have a database backup that you can look at in a text editor and search for your wp_posts table to see if you can find where that information is, and paste an example of it here. | stackexchange-wordpress | {

Upgrading PHP version results in "Use of undefined constant WP_CONTENT_DIR" warning?
On my HostGator shared hosting with a CPanel option to set PHP per domain, if I turn on PHP 7.3 (or other 7.x versions) for my existing blog I get an error page:
> Warning: Use of undefined constant WP_CONTENT_DIR – assumed ‘WP_CONTENT_DIR’ (this will throw an Error in a future version of PHP) in /my_site/public_html/wp-includes/load.php on line 141 Your PHP installation appears to be missing the MySQL extension which is required by WordPress
If I Google this, all the advice is about how to install `mysqld`, but it's surely already installed as doing a fresh install of WordPress on a separate sub-domain works perfectly under PHP 7.3, so I must be missing something in my older site's WordPress `wp-config.php`, perhaps.

Wordpress theme options checkbox default checked state
I am developing a custom theme. I added a checkbox with the settings api. They all work except for the ones that are checked by default (checked="checked"). They do not save when they get unchecked (state only, value does save).
Now, there are two things I'd like to be able to do: 1 - save the checkbox state when unchecked on default checked checkboxes. 2 - save default checked checkboxes automatically without the user first having to click "Save changes". (so on page load save default checked checkboxes for example).
**I searched everywhere for an answer already but I could not find anyone with this same question. They all handle checkboxes but none handle default "checked" checkboxes.**
The code for the checkboxes:
echo '<input type="checkbox" class="theme-custom-checkbox" name="theme_custom_option" value="1" checked="checked"' . checked( 1, get_option( 'theme_custom_option' ), false ) . ' />'; | With the code that you've added to your question, you're adding the HTML 'checked' attribute twice, which is probably why things are getting confused. You have it hard-coded as `checked="checked"`, but then `checked( 1, get_option( 'theme_custom_option' ), false )` will write another checked attribute corresponding to the actual value of the option.
You should be able to verify this would have been able to debug it by looking at the generated HTML with view-source or developer tools.
Taken from the docs page for the `checked` function in Wordpress < your code should probably look something like this:
echo '<input type="checkbox" class="theme-custom-checkbox" name="theme_custom_option" value="1" ' ;
echo checked( 1, get_option( 'theme_custom_option' ), false );
echo ' />';

Remove slashes (both before and after) in relative post url

$post_url_rel = ltrim($post_url_rel, '/');
$post_url_rel = rtrim($post_url_rel, '/');

How to get category URL with the slug?

//$ip = '185.164.57.189'; // france

$_POST field value gets altered after "init"
I'm new to wordpress development.
I'm trying to develop a simple plugin for practice. It involves a form submission from the frontend. The form has an input with the following code.
<input type='hidden' name='test' value='{"id": 1}'/>
When I submit the form, the value of 'test' field gets altered after the "init" hook.
My plugin code looks like the following
add_action('init', [$this, 'init']);
function init() {
printe_r($_POST);
}
**Output:**
Array
(
[test] => {\"id\":1}
)
The problem is that **json_decode** errors out. I have to use **stripslashes** like below to decode the json string.
json_decode(stripslashes($_POST['test']));
Is this behavior expected in Wordpress? | Yes, it's the expected behaviour. There's information on why it works like this here, and this function which can help in removing slashes from larger data structures: <
In the short term, if you can live without JSON for this field, why not just remove it, and if you need multiple hidden fields add them separately, e.g.:
<input type='hidden' name='testId' value='1'/>
<input type='hidden' name='otherId' value='123'/>
And you can get those directly with:
echo $_POST['testId'];
echo $_POST['otherId'];
Will output:

Are there any know limitations on the date field, especially how old dates can be?
Our site needs a way to order a large number of posts (think +6000). After looking at some plugins I have decided to just use the date field since it is built into wordpress.

_**Is there a limit to how far back in time posts can be dated?**_ We shouldn't have to go so far back, but I just wanted to check if anyone knew. | Almost every PHP date/time function is dealing with the UNIX epoch timestamp, which starts from 00:00:00 UTC on 1 January 1970.

How to view all currently registered block patterns?
I've registered a block pattern in my custom theme (using register_block_pattern) and it's not displaying in the block patterns list so I'm trying to debug whether I registered it properly.
How could I programmatically find currently registered block patterns? | This looks like quite new functionality, the docs say 'experimental' and the first commit of this code to the WP repo was 6 days ago from date of this writing, so wouldn't be surprised if you'll have issues with what you're doing related to it being in development.
The class that manages block patterns is easy to read:
<
So you could call e.g. the `get_all_registered()` method like:
`WP_Block_Patterns_Registry::get_instance()->get_all_registered()`
or e.g. check if your pattern is registered:
`WP_Block_Patterns_Registry::get_instance()->is_registered("your_pattern_name")`
I'd suggest if you're having problems you might either want to wait until it's a more stable feature or contact the people working on it (e.g. you could start by contacting the person who made that commit as it looks like they're actively working on it)

> Cannot find `$_FILES`, in `$_POST`, there's the filename
.. is most likely because your form tag (`<form>`) does not have the required `enctype` attribute which must be set to `multipart/form-data` to make file upload input works in that the file gets uploaded to the server — without setting the `enctype` to `multipart/form-data`, the input still works (i.e. you can select a file that you want to upload), but it'll work like a standard input field where the browser submits only the file name (e.g. `my-image.png`) and not the actual file itself (which PHP puts in the `$_FILES`).
