I'm trying to theme my Drupal site's user profile form at the moment. I'm using hook_form_alter in the theme's template.php file.
The code is the same as the code I've used to edit another form but for some reason I can't spot it's not working.
function THEME_NAME_form_alter(&$form, &$form_state, $form_id) {
if ($form_id == 'user_profile_form') {
$form['current_pass']['#prefix'] = '<div class="loginFormBlock">';
$form['current_pass']['#suffix'] = '</div>';
$form['current_pass']['#size'] = '500';
//$form['actions']['submit'] = array('#type' => 'image_button', '#src' => base_path() . path_to_theme() . '/images/Login.png');
}
}
Now the commented out submit button part works when it's un commented but the current_pass bits don't do anything. Current_pass is the name of the field I'm trying to theme. THEME_NAME has been replaced by the theme's name.
ANSWER:
As suggested I looked into the $form array.
echo '<pre>';
print_r($form);
echo '</pre>';
Saw that current_pass was in the account array and amended the code to the following, which works fine.
$form['account']['current_pass']['#size'] = '500';
Hopefully this can help someone else.
I was just going to say same thing - do a dump of $form and make sure that the field actually exists - if it does and it still doesn't work then there may be another hook being called after yours and changing your changes.
ps: I am still using D6 but are you sure your putting your form_alter function in the right place? yours says THEME_NAME_form_alter - I know in D6 you have to put them in module layer not the theme layer (unless this has changed in D7???) - could this be your issue?

I must to add new options and functions in post pages in admin panel. I call a new function in edit-form-advanced.php and edded this function in template.php file. The question is this wrong? Becouse my function is in one file with functions on wordpress. Or maybe must be in other file? but where i must call it?
For wp-content part i know and i make a child theme of parent theme, but i do not know what to do when i must add code in wp-admin part.
example:
edit-form-advanced.php
do_custom_boxes( null, $post );
and in template.php
function do_custom_boxes( $screen, $object ) {
global $wpdb;
$appTable = $wpdb->prefix . "post_panel";
$query = $wpdb->prepare("SELECT * FROM $appTable WHERE post_id = ".$_GET['post']." ", $screen);
$applications = $wpdb->get_results($query);
......
}
Short answer: Yes, it's wrong to do so. Whenever you update your WordPress you'll loose all your changes.
WordPress allows you to hook into its code, modify its behavior and many things.
Please read about actions and filters.
Basically, Actions allow you to fire a function when something happens in WordPress.
For example:
<?php
function do_something_when_admin_pages_init() {
// Do something here
}
add_action('admin_init', 'do_something_when_admin_pages_init')
Filters allow you to modify data/output of another function. It's like it let you step in the middle, do something with the data and then continue.
Example from the WordPress page:
<?php
function wporg_filter_title($title) {
return 'The ' . $title . ' was filtered';
}
add_filter('the_title', 'wporg_filter_title');
This modifies the title before it's printed.
So with those two ways of 'hooking' into the WordPress code, you can write your code in your theme's functions.php file, or write a Plugin (it's up to you).
I am having a bit of trouble here understanding how to do the following. I have searched for weeks now but cannot seem to find what I am looking for.
I have a custom post type 'product' and want to change which template gets loaded for the single product page as well as the archive for the products. I am using the following code to load include and load templates.
add_filter('template_include', function() {
if (is_post_type_archive('product')) {
$templatefilename = 'archive-product.php';
$template = WPVS_PATH . 'templates/' . $templatefilename;
return $template;
}
if ('product' == get_post_type() ){
$templatefilename = 'single-product.php';
$template = WPVS_PATH . 'templates/' . $templatefilename;
return $template;
}
});
The problem I am having is that it replaces the current theme's template instead of just the inner part of the content and archive areas.
Here is what I want to achieve:
Create a custom post type 'product' in a plugin - DONE (Was kinda easy!)
When opening a single product only change the content part. - I can do this with the_content filter hook. Simple enough. Any other suggestions is welcome.
When I go to the archive view for the 'product' custom post type I don't want to have it load the theme's default archive (list) view but instead a grid view from my plugin which I cannot seem to get right. I only want to change the inner part of the template, not the whole page.
I have created this plugin a few weeks ago using only shortcodes which works good but want to see if I can do it without the use of shortcodes by means of creating the custom post type and changing the inner template parts of the current active theme.
Can anybody steer me into the right direction here?
If I create a theme I can do what I am looking for but I want to create this into a plugin instead without adding or making changes to the active theme. The plugin should handle what is needed.
The same issue is discussed here but what I want is to develop something that is theme independent. No changes should be made in theme files and no theme files should be copied to the plugin.
WP - Use file in plugin directory as custom Page Template?
Recently I also had the same problem. Here's how I worked it out.
template_include filter accepts a parameter which is the selected template that you want to override (this what you are missing in your code).
I don't know but sometimes the filter hook need higher priority to work like 9999. But first check if it work with default priority, if don't change it.
I assume your both archive and single product template both have include get_header() and get_footer() which can be used for default selected theme (Or if the theme has different setup, setup accordingly).
This is simplified code:
add_filter('template_include', function($default_template) {
if (is_post_type_archive('product')) {
$templatefilename = 'archive-product.php';
$template = WPVS_PATH . 'templates/' . $templatefilename;
$default_template = $template;
} else if ('product' == get_post_type() ) {
$templatefilename = 'single-product.php';
$template = WPVS_PATH . 'templates/' . $templatefilename;
$default_template = $template;
}
// Load new template also fallback if both condition fails load default
return $default_template;
}, 9999); // set priority, only if not worked with default one
The best option in this case is to provide a shortcode to the user. So they can place it on any page that they want (or that you auto generate). That way you will place your content inside their theme.
Something like this:
add_shortcode( 'slotsl-game', 'embed_game' );
/**
* Print the game
* #return false|string
*/
function embed_game(){
ob_start();
$game = get_post();
include_once SLOTSL_PLUGIN_DIR . 'templates/slotsl-single-game.php';
return ob_get_clean();
}
I'm stuck. I posted this on WordPress.StackExchange and they suggested I try at WebApps.StackExchange, and they suggested I try here. So, apologies for the multiple posts if you follow all those!
I have a client blog using bit.ly pro to generate custom short urls (ie foo.co). I want to show the regular horizontal version of the Twitter button, with tweet-count, and have the link that goes to the post use their custom bit.ly pro url.
I have installed Joost de Valk's Bit.ly Shortlinks plugin, which successfully converts normal WP shortlinks (wp_get_shortlink()) to the custom Bit.ly pro URL elsewhere in the site, but Twitter seems to trump that and render everything with the default t.co domain instead.
I've looked at the suggestions from this question but using the # as the data-url doesn't work, and the suggested Twitter support pages don't seem to contain any info on how to get Bit.ly to work (though they say they're going to).
Here's the function I created to insert the button in my theme - any ideas on where I'm going wrong? this is used to insert the button both within the Loop and on single-post pages.
function tweet_this() {
global $post;
ob_start();
$tweet = wp_get_shortlink();
echo '<script src="http://platform.twitter.com/widgets.js" type="text/javascript"></script>Tweet';
return ob_get_clean();
}
In case it helps, this function does work, except it doesn't render the tweet-count:
function tweet_this() {
global $post;
ob_start();
$tweet = sprintf( __('%1$s %2$s'), $post->post_title, wp_get_shortlink() );
echo '<a class="tweethis" href="http://twitter.com/intent/tweet?text=' . urlencode( $tweet ) . ' via #clientname">Tweet this</a>';
return ob_get_clean();
}
Let me know if you need more info - and thanks in advance for any help you can throw my way!
Michelle
function tweet_this() {
global $post;
$tweet = get_permalink(); //replace with your code
$tweetmarkup = '<script src="http://platform.twitter.com/widgets.js" type="text/javascript"></script>Tweet';
echo $tweetmarkup;
}
This works for me, but I don't have the WPShortlinks installed, so I replaced it with the permalink. You should be able to replace the permalink with your wp_get_shortlink and it should work.
I want a warning message displayed in the comment form when people try to add comments:
"Please write comments in correct
grammatical English, otherwise they
will not published"
How can I do it?
Here is how you can do it by using hook_form_alter in your own module:
function mymodule_form_alter(&$form, &$form_state, $form_id) {
switch ($form_id) {
case "comment_form":
$form['#prefix'] .= "<div><p>Show some text before the comment form.</p></div>";
break;
}
}
You can alter the comment form so that your guidelines are added to it. There are a handful of ways to alter forms in Drupal. You can do it in your theme's template.php file (which I prefer for simple changes) or in a custom module. This article describes both methods, in Drupal 5 and 6, however not for the form you're interested in. However, the method used is the same that leads to the solution below. This is how you can make the change via template.php:
The following PHP code can be added to your theme's template.php file:
function YOURTHEME_theme() {
return array(
'comment_form' => array(
'arguments' => array('form' => NULL),
),
);
}
function YOURTHEME_comment_form($form) {
$output = '';
$output .= '<div class="comment-help">' . t('Please write comments in correct grammatical English, otherwise they will not published.') . '</div>';
$output .= drupal_render($form);
return $output;
}
Replace YOURTHEME with the name of your theme. If you already have a YOURTHEME_theme function you will need to add the 'comment_form' key to the array it is already returning. I doubt you do, but it's worth mentioning just in case.
A note: you should not be editing any of the themes in /themes, but you should have made a new theme or copied and renamed any of those themes into /sites/default/themes or /sites/all/themes.
The above code is based on code from this page.
Once you are inside a hook_form_alter function you can use the Development module (http://drupal.org/project/devel) dpm() function in place of var_dump to help view and isolate which properties to change in the big form arrays. I find this is a must-have when trying to figure out changes to an existing form. It puts all the elements of the form array into clickable rows.
In Drupal 7 go to
admin/structure/types/manage/mycontenttype/comment/fields/comment_body
There you can add your text. It will be shown below the field as usual. If you want the warning displayed above the field, you'd have to go the form_alter way.
I am writing a plugin that will take advantage of other plugin's features (think about a plugin for a plugin).
My file lies in /plugins/new-plugin/new-plugin.php
and I need to make a
include(/plugins/OLD_plugin/old-plugin.php)
so I can use a couple of functions from the old-plugin.php file.
What is the correct way to do this? I could maybe make the functions in old-plugin.php available globally, but I don't want to change the old-plugin.php file.
I've already tried several ways to do this, but none worked. The new-plugin will only show some info in an options page, not viewable for the general public and does not interact with any public page or post in my site.
I've already tried $_SERVER, WP_PLUGIN_DIR, WP_CONTENT_DIR, the absolute server path, relative paths and even some black magic, but nothing seems to work good.
With some of this solutions the plugin's options page shows good but the blog's pages do not render. With other solutions the inverse happens, and with some other solutions nothing even render, be it admin pages or blog's pages, all with errors regarding to file not found.
The new-plugin.php is as simple as
<?php
/*
WP Common Headers
*/
global $wpdb;
if ( ! defined( 'WP_CONTENT_DIR' ) )
define( 'WP_CONTENT_DIR', ABSPATH . 'wp-content' );
if ( ! defined( 'WP_PLUGIN_DIR' ) )
define( 'WP_PLUGIN_DIR', WP_CONTENT_DIR . '/plugins' );
include '/server-absolute-path/public_html/gameblogs/wp-content/plugins/old-plugin/old-plugin.php';
add_action('admin_menu', 'new_plugin_menu');
function new_plugin_menu() {
$page_title = 'New Plugin';
$menu_title = 'New Plugin';
$function = 'new_plugin_admin_page';
$menu_slug = 'new_plugin';
add_menu_page($page_title, $menu_title, 0, __FILE__, $function);
}
function new_plugin_admin_page() {
$result = old_plugin_link_data(" WHERE link_destination NOT LIKE '/%' AND link_destination NOT LIKE '%gameblogs%'");
$total = count($result);
old_plugin_list_links($result, $total, FALSE, FALSE);
*/
}
?>
thanks for any ideas!
check the old plugin files and see if there are any do_actions or apply_filters in it. If there are then you can hook into the old plugin script with your new plugin using add_action and apply_filters and execute other things you want to do.
see http://codex.wordpress.org/Function_Reference/do_action
and http://codex.wordpress.org/Function_Reference/apply_filters
For example (very basic example):
If in old plugin you find a:
do_action('some_type_of_reference);`
In your new plugin you can hook into it by doing:
`add_action('some_type_of_reference', 'name_of_my_function');
function name_of_my_function() {
//executed code here
}`
If in old plugin you find a:
apply_filters('some_type_of_reference', $variable);
Then in your new plugin you can hook into the filter by doing:
apply_filter('some_type_of_reference', 'my_function');
function my_function( $variable ) {
//act on the variable from the filter.
return $variable;
}
Have you looked at the plugins_url function? I haven't had an in-depth read through your code, but it might help.
The plugins_url template tag retrieves the url to the plugins directory or to a specific file within that directory. You can hardcode the plugin slug in $path or pass FILE as a second argument to get the correct folder name.
Hope this helps!
