Here's the context. I have a Joomla Backend with tons of custom code in a very old Joomla 1.X version. Everything is still surprisingly holding up well. The site owner wants a new front facing website and his company chose WordPress. Website was built, now we want to add a log in form to the Joomla backend from a WP page.
Here's what worked:
Go to Joomla login page (domain.com/administrator)
Copy the HTML form (including hidden input with token)
Paste the HTML and adjust the action attribute of the form
Went to the WP page (domain.com/wordpressFolder/page, entered credentials and it works perfectly!
Obviously these tokens can only be used once. Added a shortcode in WP that gets the form from Joomla and "extract" the token and returns it to the page.
function st_login_form( $atts ) {
$joomla = file_get_contents('http://www.example.com/administrator/index.php');
$doc = new DOMDocument();
$doc->loadHTML($joomla);
$inputs = $doc->getElementsByTagName('input');
$token = $inputs[5]->attributes[1]->nodeValue;
$html = '<form action="https://www.example.com/administrator/index.php" method="post" name="login" id="form-login" style="clear: both;">
<p id="form-login-username">
<label for="modlgn_username">Username</label>
<input name="username" id="modlgn_username" type="text" class="inputbox" size="15">
</p>
<p id="form-login-password">
<label for="modlgn_passwd">Password</label>
<input name="passwd" id="modlgn_passwd" type="text" class="inputbox" size="15">
</p>
<input type="submit" value="Connexion" />
<input type="hidden" name="option" value="com_login">
<input type="hidden" name="task" value="login">
<input type="hidden" name="'.$token.'" value="1">
</form>';
return $html;
}
The code behaves has expected and inspecting the form on the WP page with injected token looks fine, however when logging in it gives me an invalid token error.
I don't quite understand why it works when copy pasting but not when I retrieve the token from PHP. Any clue or potential solutions?
Found my first mistake. The GET is done over HTTP while the POST is sent over HTTPS. Obviously, CSRF token are domain-signed.
Now it simply redirects me to the login page but I'm not logged in.
I created a front end registration form, I used the filters 'registration_errors' to customize the messages.
After WP detects the error and use 'wp-redirect' to return to the registration page and display an error if the email or the user exists for example.
My question is: how I can keep the previous values that generated the error.
¿JS?
Thanks in advance!
To keep values in the form after the error message:
function my_register_sesion (){
session_start();
$_SESSION['key_login']=$_REQUEST['user_login'];
$_SESSION['key_email']=$_REQUEST['user_email'];
}
add_action ('register_post', 'my_register_sesion');
My inputs form should be as follows:
<input type="text" name="user_login" id="user_login" class="input" value="<?php echo $_SESSION['key_login'];?>">
<input type="text" name="user_email" id="user_email" class="input" value="<?php echo $_SESSION['key_email'];?>">
Thank you David!
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.
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:
Settings API tutorial.
Settings API documentation.
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">
