Parameterized shortcodes - php

I'm by no means a PHP guru and have been given the task of updating a WordPress site. I've managed to get my php-includer plugin to work so that I can use a shortcode within the content area which the editor can then reference a stand-alone file which will then get injected into the main page.
The code I'm using is this:
<?php
function PHP_Include($params - array()) {
extract(shortcode_atts(array(
'file' => 'default'
), $params));
ob_start();
include(get_stylesheet_directory() . "/inc/$file.php");
return ob_get_clean();
}
add_shortcode('phpinclude', 'PHP_Include');
?>
I've saved this as a plugin and then using [phpinclude file='testfile'] in the content on a blog post. While the external testfile.php is included into the content, what I am after is a way of targeting parameters.
So for example, if the page held 4 images, I could specify in a parameter how many I would want to display. The editor could then add the following code [phpinclude file='testfile' images=2]. This would then display only 2 images instead of the default 4 images.
Does anyone know of a way to do this with the code I've shown above or point me in the right direction?

If you just add that parameter to your shortcode:
<?php
function PHP_Include($params - array()) {
extract(shortcode_atts(array(
'file' => 'default',
'images' => 4
), $params));
ob_start();
include(get_stylesheet_directory() . "/inc/$file.php");
return ob_get_clean();
}
add_shortcode('phpinclude', 'PHP_Include');
?>
then the $images variable containing the number of images to display is available to the code of your included PHP file, which can act upon it accordingly.

Editing serialized data WordPress dashboard

I just inherited a custom plugin that takes Formstack submissions and creates WordPress posts from them. The posts are created fine, however the form contents are stored as serialized data in post_content.
I am tasked with enabling these posts to be edited within the WP Dashboard. Currently when you click on a post title, you are presented with a page that just shows the data; no capability to edit the data.
Enabling the editor controls within "supports" in the functions.php file gives me the editor with the serialized data just dumped in the editor.
I have never had to setup a custom edit page for a specific post type in WP. Is there someone out there who can direct me so a site that explains this? I'm running in circles.
You can filter the content before it is presented in the admin editing screen.
function my_filter_function_name( $content, $post_id ) {
if(get_post_type($post_id) == 'the_post_type_in_question'){
$serialized_content = $content;
$content_array = unserialize($serialized_content);
// do something with this array to put it in the format you want
// .....
$content = $new_formatted_content;
}
return $content;
}
add_filter( 'content_edit_pre', 'my_filter_function_name', 10, 2 );
But, that doesn't seem like it's going to be of much use to you.
In your situation, I suggest you take the time to write a script to convert all those posts so that everything is stored as post meta. (create the custom fields, first).
If your theme isn't built on any framework, then I think the quickest way to create a custom field is to use the Advanced Custom Fields plugin.
Then, once you know the meta_keys, you can write that script. E.g.
$posts = get_posts('post_type'=>'the_post_type','posts_per_page'=> -1);
foreach($posts as $post){
$content_array = unserialize($post->post_content);
// how you do the next bit will depend on whether or not this is an associative array. I'm going to assume it is (because it's a little easier :) )
foreach($content_array as $meta_key=>$meta_value){
update_post_meta($post->ID, $meta_key, $meta_value);
}
// just put what you actually want as the post content back into the post content:
wp_update_post(array('ID'=>$post->ID,'post_content'=>$content_array['post_content'])); // assuming the key of the element you want to be the post content is 'post_content'
}
To run this script, you could simply create a temporary new page and then create a template file specifically for that page and put the above code into that file (then visit the page).
You need to modify the plugin so that the data is unserialized before modifying, then serialized before saving to DB...
Alternatively, try using WP's CORE functionality:

Create new page in drupal

Iam new in drupal. I want to create a page and want to add data in page directly with out using backend content. I have created a page like this, page-test.tpl.php. How can I call this newly created page in browser?
First you have to create your own custom module.Let the module name be test.Create 2 files namely test.info and test.module.Declare a hook_menu function inside the test.module file.Since your module name is test your hook_menu will be named as test_menu.
Hook_menu enables modules to register paths in order to define how URL requests are handled. Paths may be registered for URL handling only, or they can register a link to be placed in a menu.
Test.module
function test_menu() {
$items = array();
$items['test'] = array(
'title' => 'My Page',
'description' => 'Study Hard',
'page callback' => 'test_simple', //Calls the function
'access arguments' => array('access content'),
);
return $items;
}
function test_simple() {
return array('#markup' => '<p>' . t('My Simple page') . '</p>');
}
Test.info
name = Test
description = Provides a sample page.
core = 7.x
After adding this try clearing the drupal cache and then navigate to /test.Try this link if you are a beginner.Try reading hook_theme which allows you to use your custom template.More about hook_theme here.Hope it might help u mate.. :)
Pages in drupal are stored in the database, not in actual code files like old websites used to. The template files (.tpl.php) are exactly that - templates. So for example, lets say you have blog content. You'd have to create a content type of 'Blog'. you could then create a template file (ex. node--blog.tpl.php) which would format the way the blog pages would look. But you would still need to add new pages through the drupal interface in order to add them to the site. You could always use an input type of PHP if you'd like to include php in the body of the page.
If you simply want to display a php file in your browser from your site, you can just upload a php file of your choice to your sites/default/files directory and access it directly via the file path.

Is there a cleaner way to write this avoiding includes

I'm writing a project in php that will basically give me a webpage with links to things like:
a page containing my favorite youtube videos stored in a mysql db
a page with all my favorite games
and music ect
All will be embeded directly inside the webpage rather than linking to the site.
To simplify this I've made a master template "index.php" and then using $_GET I pass pages and other info through to the template which is then handled by a page check script which performs a number of ifs to determine what php script to load into the website.
Where my question lies is whats the prefered method for loading theese scripts into the website as my current method is
if ($_GET["page"] == "videos"){
include ("dynapage/scripts/videos/videos.php");
}
if ($_GET["page"] == "music"){
include ("dynapage/scripts/music/music.php");
}
ect
Is using includes to add this code into my template a good thing to do or is there a better method you can suggest?
note: checks for isset are already included in the checks and aditional pbs are availble on request.
Use an array which has the $_GET["page"] value as key and the php filename as value. You then only need to check if it is inside the array and if so, include it. You then write the values into the array instead of writing many if clauses.
The following code example shows this, additionally it has a function to load a page because so the included script does not set variables in the context it gets included into by accident.
$pages = array(
'videos' => 'videos/videos.php',
'music' => 'music/music.php',
);
/**
* include a page template
*/
function load_page(array $pages, $page, $path = 'dynapage/scripts')
{
if (isset($pages[$page])) return;
include ($path.'/'.$pages[$page]);
}
if (isset($_GET['page']))
{
load_page($pages, $_GET['page']);
}
Maybe Something like this:
$config = array(
'videos' => 'dynapage/scripts/videos/videos.php',
'music' => 'dynapage/scripts/music/music.php'
);
if(isset($config[$_GET['page']])) {
include($config[$_GET['page']]);
}
is a bit better, then writing many if clauses (;
Looks like you can just do:
if( file_exists($fn = "dynapage/scripts/".$_GET['page']."/".$_GET['page'].".php"))
include($fn);

Drupal: Inserting fivestar widget in an external php file

I have been trying to load fivestar module and show the rating widget of the selected node in an external php file. I have gotten the rating widget displayed on the page but it only displays degraded version of the widget (non-JavaScript, dropdown widget and "Rate" button) I looked into the source code of the page but the javascript for fivestar module was not loaded. I have tried to load javascript using following functions but had no luck:
fivestar_add_js();
$path = drupal_get_path('module','fivestar');
drupal_add_js($path.'/js/fivestar.js', 'inline', 'footer');
The following is the code in the php file:
//require the bootstrap include
require_once 'includes/bootstrap.inc';
//Load Drupal
drupal_bootstrap(DRUPAL_BOOTSTRAP_FULL);
fivestar_add_css();
// I have used one of the following two functions one at a time to test.
fivestar_add_js();
$path = drupal_get_path('module','fivestar');
drupal_add_js($path.'/js/fivestar.js', 'inline', 'footer');
$book = $_GET["book"];
$chap = $_GET["chap"];
$prob = $_GET["prob"];
$string = $book.'/'.$chap.'/'.$prob;
$query = "SELECT ctcr.nid FROM content_type_comments_ratings AS ctcr WHERE ctcr.field_problem_value = '".$string."'";
$result=db_query($query);
$row = db_fetch_array($result);
if(isset($row['nid']))
{
$nid = $row['nid'];
node_load(FALSE, NULL, TRUE);
$fivestar = node_load($nid, NULL, TRUE);
if (function_exists('fivestar_widget_form')) print fivestar_widget_form($fivestar);
}
If you could give me a hint or direct me to some reading on the web, I would appreciate it. Thank you very much in advance.
By doing all this on an 'external' page/file, you circumvent the Drupal theming system - drupal_add_js() (and fivestar_add_js(), as it is just using that in the end) do not output the script tags themselves, but simply ensure that they will be included in the $scripts variable in page.tpl.php, which is then responsible to print that variables content. As you do not go through the page template, you get no script tags.
You could do a print drupal_get_js(); in your external file to output the scripts added via drupal_add_js() as a quick fix, but note that this will output all the default drupal js files as well, which might be more than you need (but might as well contain other scripts needed by fivestar, e.g. jquery). Alternatively, you'll have to create the needed script tags yourself.
As for hints on what to read, it is difficult to point you to something particular, but you might want to read up on the theming system in general.

Wordpress - use comment-system outside of pages and posts

so currently i'm using pods to create some individual pages for a log, filled with custom stuff.
now i want to use the comments-system for each of this pages e.g.:
mydomain.com/podpages/page1
mydomain.com/podpages/page2
mydomain.com/podpages/page3
this are not pages created with wordpress so simply adding <?php comments_template(); ?> is not working.
any ideas how to solve this problem?
thanks in advance
please leave a comment if something is unclear :)
When a comment is stored in the WordPress database, the ID of the post (or page) the comment relates to is also stored.
Trouble is, you're trying to save comments using WordPress, but for a page that it doesn't actually know about.
So, how about we create a WordPress page for each real page, but merely as a representation, so that your real pages and WordPress have a common ground for working with each other.
So, the plan here is to;
Load WordPress in the background on each of the 'real' pages.
See if a WordPress page representation already exists for the 'real' page
If it doesn't, create it, then and there
Trick WordPress into thinking we're actually viewing the representation
Carry on using all of WP's functions and 'template tags' as you would normally
This code should be somewhere at the beginning of the template file used to render your 'real' pages;
include ('../path/to/wp-load.php');
// remove query string from request
$request = preg_replace('#\?.*$#', '', $_SERVER['REQUEST_URI']);
// try and get the page name from the URI
preg_match('#podpages/([a-z0-9_-]+)#', $matches);
if ($matches && isset($matches[1])) {
$pagename = $matches[1];
// try and find the WP representation page
$query = new WP_Query(array('pagename' => $pagename));
if (!$query->have_posts()) {
// no WP page exists yet, so create one
$id = wp_insert_post(array(
'post_title' => $pagename,
'post_type' => 'page',
'post_status' => 'publish',
'post_name' => $pagename
));
if (!$id)
do_something(); // something went wrong
}
// this sets up the main WordPress query
// from now on, WordPress thinks you're viewing the representation page
}
UPDATE
I can't believe I was this stupid. Below should replace current code inside outer if;
// try and find the WP representation page - post_type IS required
$query = new WP_Query(array('name' => $pagename, 'post_type' => 'page'));
if (!$query->have_posts()) {
// no WP page exists yet, so create one
$id = wp_insert_post(array(
'post_title' => $pagename,
'post_type' => 'page',
'post_status' => 'publish',
'post_name' => $pagename,
'post_author' => 1, // failsafe
'post_content' => 'wp_insert_post needs content to complete'
));
}
// this sets up the main WordPress query
// from now on, WordPress thinks you're viewing the representation page
// post_type is a must!
wp(array('name' => $pagename, 'post_type' => 'page'));
// set up post
the_post();
P.S I think using the query_var name over pagename is better suited - it queries the slug, rather than the slug 'path'.
You'll also need to either place an input inside the form with name redirect_to and a value of the URL you'd like to redirect to, or, filter the redirect with a function hooked onto comment_post_redirect, returning the correct URL.
add
require('/path/to/wp-blog-header.php');
to include the wp files. this should give you all the functions/data you need.
Can you create pages in wordpress which display your log data? You might need a new template for this. WordPress will then have something to connect the comments to.
Do you need to use WordPress for this? If not, maybe something in this SO question helps: Unobtrusive, self-hosted comments function to put onto existing web pages
Just supply the wordpress-comment-part with a new ID - start with something your usual posts will never reach (100.000+ is your pages i.e.)
I don't know exactly if in wordpress it's a function (saveComment i.e.), but if it is so, just use it in your page with he custom ID.
You will nevertheless have to insert the Comments-form yourself.
And don't forget to modify the query that gets the news-entires that IDs over 100.000 are not entries.
Or you can write your own template that displays the standard-Worpress-stuff with IDs < 100.000, or else your pages.
Summed up, it should not be very difficult.
p.s.: If you just want to use the wordpress-login, then use any comment-system or make your own (it's an 1hour-thing) and authenticate / use the worpress-session.
