WordPress: Disable add custom field - wordpress

I allow a guest to post on my WordPress site. I disabled some fields, but I let the user select only one field.
Cool, but he can edit this field.
Example: Field: name.
After I added it, he can rename the field to name2.
So, how do I can a disable this?

Use the readonly attribute,
<input type="text" name="test" value="<?php echo $name ?>" readonly="readonly">

Display in woocommerce order management page custom made <input fields> for shipping methods

I have created the following code which I have added to the PHP function to create two input fields placed just below the fixed-rate shipping method on the check out page. In these two input fields customers can enter their shipping provider and account number.
The input fields work perfectly, the problem is that when the order is placed, the values entered (shipping provider name and account number) in these two fields do not appear in the order details on woocommerce.
Can you please advise me how I can make the two fields appear on the woocommerce order management page so that I know what customers have entered?
code:
function checkout_shipping_additional_field( $method, $index )
{
if( $method->get_id() == 'flat_rate:35' ){
echo '<br>
<input type="text" id="Name" name="Name" placeholder="Shipping Provider">
<input type="text" id="Name" name="Name" placeholder="Account Number">';
}
}

How can i connect custom HTML form with wordpress email adress

I am using Wordpress and framework Gantry 5, I have custom html form added via JS as an innerHTML added to existing container.
I want this form values be submitted to email adress defined in WordPress administration settings. Is there any way i can achieve it?
it depends from the form action, if your form action call a function inside your wordpress (for example in function.php) you can pick the email address
get_option('admin_email')
and use it to send the post data.
If the form action call a function external to you wordpress you can add the email as an hidden field in your form
<input type="hidden" id="email" name="email" value="<?php echo get_option('admin_email'); ?>">
and get the value in the $_POST object.
Because you form is added by javascript you can add the hidden field by javascript before the form submit maybe using jquery (you also can do this in vanilla js).
If you print the script directly inline with php
$("#yourFormID").submit( function(eventObj) {
$("<input />").attr("type", "hidden")
.attr("name", "email")
.attr("value", "<?php echo get_option('admin_email'); ?>" )
.appendTo("#form");
return true;
});
If you put the script in js file you can print the hidden field outside with php and then pick the value with jquery (or also vanilla)
<input type="hidden" id="email" name="email" value="<?php echo get_option('admin_email'); ?>">
$("#yourFormID").submit( function(eventObj) {
$("<input />").attr("type", "hidden")
.attr("name", "email")
.attr("value", $('#email').val() )
.appendTo("#form");
return true;
});

Wordpress : Adding meta box in Admin Menu page

I am working on a plugin, which creates a couple of Virtual pages, and I wish these links to be available in Menu admin page, to let users have the liberty to add them as they create menus.
I want to add a Meta box in Menu administration, very similar to Page/Category meta boxes, to let users select what page to add in their menu.
Apparently, the only possible research is in the core itself.
Here, /wp-includes/nav-menu.php, we can get how to insert the meta box:
add_action('admin_init', 'so_13875144_nav_menu_meta_box');
function so_13875144_nav_menu_meta_box() {
add_meta_box(
'my-custom-nav-box',
__('Custom Box'),
'so_13875144_display_menu_custom_box',
'nav-menus',
'side',
'default'
);
}
function so_13875144_display_menu_custom_box() {
/* Not sure about this global var */
//global $_nav_menu_placeholder;
//$_nav_menu_placeholder = ( 0 > $_nav_menu_placeholder ) ? intval($_nav_menu_placeholder) - 1 : -1;
?>
<p id="menu-item-custom-box">
<label class="howto" for="custom-menu-item-custom-box">
<span><?php _e('URL'); ?></span>
<input id="custom-menu-item-custom-box" name="menu-item[<?php echo $_nav_menu_placeholder; ?>][menu-item-custom-box]" type="text" class="code menu-item-textbox" value="my text" />
</label>
</p>
<?php
}
But, the hard part, which I haven't managed to make work, is to save the value.
This is the file /wp-admin/nav-menus.php that has to be studied.
Tried to hook into the action wp_update_nav_menu, but the custom meta box input field is not being passed into $_POST.
WordPress Answers may have some hint: https://wordpress.stackexchange.com/search?q=wp_update_nav_menu
http://codex.wordpress.org/Function_Reference/add_meta_box
Use the post_type 'nav-menus'
I know I'm late to the party but just for anyone else trying to do this...
b__ is right, that is the way to get it to show on the page except it is much easier to use checkboxes than any other field because there is an inbuilt javascript function that looks for checkboxes.
All you need to do is copy the html from an existing checkbox -
<li><label class="menu-item-title"><input type="checkbox" class="menu-item-checkbox" name="menu-item[-1][menu-item-object-id]" value="2"> Sample Page</label><input type="hidden" class="menu-item-db-id" name="menu-item[-1][menu-item-db-id]" value="0"><input type="hidden" class="menu-item-object" name="menu-item[-1][menu-item-object]" value="page"><input type="hidden" class="menu-item-parent-id" name="menu-item[-1][menu-item-parent-id]" value="0"><input type="hidden" class="menu-item-type" name="menu-item[-1][menu-item-type]" value="post_type"><input type="hidden" class="menu-item-title" name="menu-item[-1][menu-item-title]" value="Sample Page"><input type="hidden" class="menu-item-url" name="menu-item[-1][menu-item-url]" value=""><input type="hidden" class="menu-item-target" name="menu-item[-1][menu-item-target]" value=""><input type="hidden" class="menu-item-attr_title" name="menu-item[-1][menu-item-attr_title]" value=""><input type="hidden" class="menu-item-classes" name="menu-item[-1][menu-item-classes]" value=""><input type="hidden" class="menu-item-xfn" name="menu-item[-1][menu-item-xfn]" value=""></li>
but give them each a unique ID and put your details in for the URL, title etc.
Then, add a submit button at the end to add to the menu -
<input type="submit" class="button-secondary submit-add-to-menu right" value="<?php esc_attr_e('Add to Menu'); ?>" name="YOUR NAME" id="YOUR ID" onclick="(function(){$('#THE DIV YOU HAVE PUT YOUR LIST IN').addSelectedToMenu( api.addMenuItemToBottom );})"/>
And that should add the item to the list.
This is a pretty old question but I was trying to do this today so in case it points anyone in the right direction...
I won't cover adding the meta box, as it's covered above. I'll also only cover a custom link as I haven't looked into adding a post, page, term link etc.
Just to cover the logic of how I got there...Looking at wp-admin/js/nav-menu.js, for a custom link you'll want to use window.wpNavMenu.addItemToMenu(). This ajax submits to the function wp_ajax_add_menu_item() in wp-admin/includes/ajax-actions.php. This then submits to wp_save_nav_menu_items() in wp-admin/includes/nav-menu.php. The upshot from looking at these files is that all menu items are of a post_type, taxonomy, post_type_archive or custom type.
Hook the javascript to the HTML as you wish, but if you want to submit a custom link, you need to call addItemToMenu() as follows:
var url = 'http://example.com';
var title = 'Link text';
window.wpNavMenu.addItemToMenu({
'-1': {
'menu-item-type': 'custom',
'menu-item-url': url,
'menu-item-title': title,
}
}, window.wpNavMenu.addMenuItemToBottom);
Menu item type has to be "custom" otherwise it requires info for a post, page etc. with which to associate the menu item.

How to create new pages in wordpress admin panel

I am trying to create a separate menu section on wordpress admin panel which will contain three pages. The pages will behave exactly like the normal wordpress pages, I just want to have a separate menu section in the admin panel. I am able to use wp_editor() to display the editor within a form. My problem is how do I get the content from the editor and how do save into the wp_post in the database? Here is the piece of code I have already come up with:
<?php
$content = '';
wp_editor('test', 'mydescription', array('textarea_name' => 'my_description', 'tinymce' => true));
?>
<p><div class="submit"><input type="submit" name="save_front_content_options" value="<?php _e('Save Changes', 'save_options') ?>" style="font-weight:bold;" /></div></p>
<input type="hidden" name="action" value="save" />
</form>
If I understand correctly, you are looking for the Settings API:

Creating wp plugin for external login => post comments

I need to create a wordpress plugin to connect wordpress to a central login. But all I want is the user to be able to post comments with name and email filled. I don't think I need create a real loggin into wordpress because the user should not be able to write posts or do admin stuff. I want him only to post comments.
I search the documentation but could not find any action for comments.
How can I change the html of a comment form?
Maybe not good but it works...
Fill comment author and email from central login stored in session:
function portal_user_comment()
{
$_POST['author'] = $_SESSION['portal']['name'];
$_POST['email'] = $_SESSION['portal']['email'];
}
add_action('pre_comment_on_post', 'portal_user_comment');
Edit comments.php from the template. Look for:
<input type="text" name="author" id="author" value="<?php $comment_author; ?>" ...>
<input type="text" name="email" id="email" value="<?php $comment_author_email; ?>" ...>
Set both fields disabled="true" and replace the values with the author and email from the session.
