Longer Form Fields in Drupal - php

I have a really silly problem that has cost me a load of time already.
I have created a content template with a URL in there. When I look at the HTML code for it, I see a big fat "maxlength=256" in the form tag. I'd like to expand the length of this field, because my customer wishes to enter really long links (over 500 characters). Any idea how I can change it? When I do a generic search through the code I see so many occurences of 256, but the length might just as well be in the database somewhere. I have of course made the database field a longer varchar (1024 sounded poetic to me), so that's something I don't have to worry about.
I think it's silly, but the customer's always right, as we know.
I am using Drupal 6.14.

You want to use a hook_form_alter() in your templete.php or a custom module.
It will look something like this:
MODULE_form_alter(&$form, &$form_state, $form_id) {
if($form_id = 'name_of_form_you_want_to_alter') {
form['name_of_url_field']['#maxlength'] = 500;
}
}
Just replace MODULE with the name of your theme (if in template.php) or replace it with the name of the custom module your using.
To find the id of the form, inspect the element with firebug. Same goes for the id of the url field.
Let me know if you need more detail.
EDIT: As pointed out, it looks like you can't call hooks from the theme level.
The best way to go about this is to create a small custom module for you site. You can call it something like SITENAME_customizations.
All you need is a simple .info file named MODULENAME.info which will look something like this:
name = SITE customizations
description = "Customizations"
You will also need a MODULENAME.module file, which is where you will include your hook_form_alter call.
PS. Make sure that you don't close your php tag (?>) in your .module file.

Yahoooooo! I fixed it, thanks to the helpful Drupal pages:
http://drupal.org/node/300705
I figured out I could edit the form after it has been generated completely. The solution presented by Erik is good, but doesn't appear to work for CCK fields. In my case Erik's solution could have worked if it wasn't for this generation step that needs to happen first.
My new code is as follows:
function longerfield_form_alter(&$form, &$form_state, $form_id) {
$form['#after_build'][] = 'longerfield_after_build';
}
function longerfield_after_build($form, &$form_state) {
// This is for a node reference field:
$form['field_page_boeken'][0]['data']['url']['#maxlength'] = 1024;
return $form;
}
Now, I too see that it's ugly, especially because there might be other form elements here (just increment from 0), but it works for the first element! Yippeee!

Using shortcode in HREF in content loaded via functions.PHP

Wordpress | Advanced Custom Fields plugin
I created a new field in the editor where my colleagues can fill in a URL relevant to that specific page. This URL will be used in the button we load on every single job listing page. This button is created within the functions.php file:
function my_editor_content( $content ) {
$content = "<h3>Title</h3><p>text</P>
<a href='[acf field='afas_url']' target='_blank' rel='noopener'><button>Solliciteer Nu</button></a>";
The above is cut off at the 'afas_url' part. So, I think it has something to do with the quotations marks and probably not even hard to fix, but as I'm just starting to figure things out I couldn't find the answer myself yet.
I hope it's a clear enough explanation :)
(And maybe it's not best practice to use functions.php but it was already like this)

Custom Taxonomy Term page in Drupal 7

I'm trying to make a custom Taxonomy Term page in Drupal 7. I've created a page--taxonomy.tpl.php file in my templates folder. The file only prints out a message. I now try to force the template file by adding
function template_preprocess_page($variables) {
if (arg(0) == 'taxonomy') {
$variables['template_file'] = 'page--taxonomy-tpl';
}
}
in my template.php, but it won't work. Can you help me? And if I get the custom page working, how do I fetch the nodes with this term (in page--taxonomy.tpl.php)? Thanks in advance.
Try using this in your template.php:
function template_preprocess_page(&$variables) {
if (arg(0) == 'taxonomy') {
$variables['theme_hook_suggestions'][] = 'page__taxonomy';
}
}
You need to pass $variables by reference, so add a & before it
template_file has changed to theme_hook_suggestions in Drupal 7
You don't need the -tpl in the template suggestion unless you want it to be a part of the filename like "page--taxonomy-tpl.tpl.php" which I don't think is what you want.
For more information, check out template_preprocess_page(), theme_get_suggestions() and Working with template suggestions
Not sure if this would meet your requirements, but one of default D7 views - Taxonomy term - emulates Drupal core's handling of taxonomy/term pages. You could just enable it (it would automatically replace Drupal's core taxonomy URLs), and then do whatever you want with it, keeping original page structure, all blocks etc, using Views' page templates (see "Theming information" in "Advanced") and all other bells and whistles...
Since you are using Drupal 7, you could also create a file name "taxnomy-term.tpl.php" and edit according to your needs.
See taxonomy-term.tpl.php
Full control over the taxonomy term page can be obtained using hook_menu_alter() . See https://drupal.stackexchange.com/questions/48420/theming-and-overriding-taxonomy-term-vocabulary-page/111194#111194

Drupal Form-API: #field_prefix doesn't work on textfield

I'm trying to implement #field_prefix on a text field so I can add some extra UI to my form.
I have a module where I'm doing other overrides like this, with a function that basically looks like this:
function modulename_form_alter(&$form, $form_state, $form_id){
if ($form_id == "contenttype_node_form"){
$form['field_contenttype_fieldname'][0]['#prefix'] = 'prefix'; //this line works
$form['field_contenttype_fieldname'][0]['#field_prefix'] = 'field_prefix'; //this line doesn't work
}
Here's the docs, seems pretty straight forward:
http://api.drupal.org/api/file/developer/topics/forms_api_reference.html/6#field_prefix
I've renamed my theme to effectively disable it - should prove I don't have any other overrides hanging around that would conflict.
What am I missing?
Update:
Ended up overriding theme_form_element to insert my prefix manually when the #field_name meets the right condition. Feels hacky, but text_textfield simply doesn't support #field_prefix.
My guess is that as a CCK field field_contenttype_fieldname isn't actually a textfield, but a custom FormAPI field CCK provides that's like a textfield, and as such it doesn't consume the field_prefix attribute.
Try print_r()ing that field out of the $form and see what its #type is.

Changing CCK Title for Form

By default a CCK form creation has a title of the form
Create [Your Content Type Name Here]
I want to change mine to
Register for Such and Such
It was suggested that I could use string-override, but I can't find the string to replace. I've also tried writing code to form_alter, but can't seem to figure out how to get the "title" to change.
Ideas?
There are two possibilities, either you can use the theming laying and set $title variable used in the page templage. You can do this with a preprocess function like lazy suggests.
The other options which I prefer would be to use the drupal_set_title(), this would need to go in a module. I haven't tried this, but I would think that you could use this in your hook_form_alter() implementation. That way you could control which titles get changed pretty easily.
Hook form_alter doesn't affect the title, but you can use a preprocess function:
Try this code to start:
function MYMODULENAME_preprocess(&$variables) {
$variables['title'] = 'test title';
}

displaying a Drupal view without a page template around it

I would like to display a Drupal view without the page template that normally surrounds it - I want just the plain HTML content of the view's nodes.
This view would be included in another, non-Drupal site.
I expect to have to do this with a number of views, so a solution that lets me set these up rapidly and easily would be the best - I'd prefer not to have to create a .tpl.php file every time I need to include a view somewhere.
I was looking for a way to pull node data via ajax and came up with the following solution for Drupal 6. After implementing the changes below, if you add ajax=1 in the URL (e.g. mysite.com/node/1?ajax=1), you'll get just the content and no page layout.
in the template.php file for your theme:
function phptemplate_preprocess_page(&$vars) {
if ( isset($_GET['ajax']) && $_GET['ajax'] == 1 ) {
$vars['template_file'] = 'page-ajax';
}
}
then create page-ajax.tpl.php in your theme directory with this content:
<?php print $content; ?>
Based on the answer of Ufonion Labs I was able to completely remove all the HTML output around the page content in Drupal 7 by implementing both hook_preprocess_page and hook_preprocess_html in my themes template.php, like this:
function MY_THEME_preprocess_page(&$variables) {
if (isset($_GET['response_type']) && $_GET['response_type'] == 'embed') {
$variables['theme_hook_suggestions'][] = 'page__embed';
}
}
function MY_THEME_preprocess_html(&$variables) {
if (isset($_GET['response_type']) && $_GET['response_type'] == 'embed') {
$variables['theme_hook_suggestions'][] = 'html__embed';
}
}
Then I added two templates to my theme: html--embed.tpl.php:
<?php print $page; ?>
and page--embed.tpl.php:
<?php print render($page['content']); ?>
Now when I open a node page, such as http://example.com/node/3, I see the complete page as usual, but when I add the response_type parameter, such as http://example.com/node/3?response_type=embed, I only get the <div> with the page contents so it can be embedded in another page.
I know this question has already been answered, but I wanted to add my own solution which uses elements of Philadelphia Web Design's (PWD) answer and uses hook_theme_registry_alter, as suggested by Owen. Using this solution, you can load the template directly from a custom module.
First, I added raw.tpl.php to a newly created 'templates' folder inside my module. The contents of raw.tpl.php are identical to PWD's page-ajax.tpl.php:
<?php print $content; ?>
Next, I implemented hook_preprocess_page in my module in the same fashion as PWD (except that I modified the $_GET parameter and updated the template file reference:
function MY_MODULE_NAME_preprocess_page(&$vars) {
if ( isset($_GET['raw']) && $_GET['raw'] == 1 ) {
$vars['template_file'] = 'raw';
}
}
Finally, I implemented hook_theme_registry_alter to add my module's 'templates' directory to the theme registry (based on http://drupal.org/node/1105922#comment-4265700):
function MY_MODULE_NAME_theme_registry_alter(&$theme_registry) {
$modulepath = drupal_get_path('module','MY_MODULE_NAME');
array_unshift($theme_registry['page']['theme paths'], $modulepath.'/templates');
}
Now, when I add ?raw=1 to the view's URL path, it will use the specified template inside my module.
For others who may hit this page, if you're just working with standard callbacks (not necessarily views), this is easy. In your callback function, instead of returning the code to render within the page, use the 'print' function.
For example:
function mymodule_do_ajax($node)
{
$rval = <<<RVAL
<table>
<th>
<td>Data</td>
<td>Data</td>
<td>Data</td>
</th>
<tr>
<td>Cool</td>
<td>Cool</td>
<td>Cool</td>
</tr>
</table>
RVAL;
//return $rval; Nope! Will render via the templating engine.
print $rval; //Much better. No wrapper.
}
Cheers!
Another way to do it which I find very handy is to add a menu item with a page callback function that doesn't return a string:
Example:
/**
* Implementation of hook_menu.
*/
function test_menu(){
$items['test'] = array (
/* [...] */
'page callback' => 'test_callback',
/* [...] */
);
return $items;
}
function test_callback() {
// echo or print whatever you want
// embed views if you want
// DO NOT RETURN A STRING
return TRUE;
}
-- Update
It would be much better to use exit(); instead of return TRUE; (see comment).
Hey, here's yet another way of doing it:
1) Download and install Views Bonus Pack (http://drupal.org/project/views_bonus)
2) Create a Views display "Feed" and use style "XML" (or something you think fits your needs better).
3) If you're not satisfied with the standard XML output, you can change it by adjusting the template for the view. Check the "theme" settings to get suggestions for alternative template names for this specific view (so you'll still have the default XML output left for future use).
Good luck!

Based on answer of Philadelphia Web Design (thanks) and some googling (http://drupal.org/node/957250) here is what worked for me in Drupal 7 to get chosen pages displayed without the template:
function pixture_reloaded_preprocess_page(&$vars)
{
if ( isset($_GET['vlozeno']) && $_GET['vlozeno'] == 1 ) {
$vars['theme_hook_suggestions'][] = 'page__vlozeno';
}
}
instead of phptemplate, in D7 there has to be the name_of_your_theme in the name of the function. Also, I had to put two underscores __ in the php variable with the file name, but the actual template file name needs two dashes --
content of page--vlozeno.tpl.php :
<?php print render($page['content']); ?>
The output, however, still has got a lot of wrapping and theme's CSS references. Not sure how to output totally unthemed data...
Assuming you're in Drupal 6, the easiest way to do this is to put a phptemplate_views_view_unformatted_VIEWNAME call in template.php (assumes your view is unformatted - if it's something else, a list say, use the appropriate theme function). Theme the view results in this theme call then, instead of returning the results as you normally would, print them and return NULL. This will output the HTML directly.
PS - make sure to clear your cache (at /admin/settings/performance) to see this work.
there are probably a number of ways around this, however, the "easiest" may be just setting your own custom theme, and having the page.tpl.php just be empty, or some random divs
// page.tpl.php
<div id="page"><?php print $content ?></div>
this method would basically just allow node.tpl.php to show (or any of drupal's form views, etc...) and would be an easy way to avoid modifying core, or having to alter the theme registry to avoid displaying page.tpl.php in the first place.
edit: see comments
ok i played around with views a bit, it looks like it takes over and constructs it's own "node.tpl.php" (in a sense) for display within "page.tpl.php". on first glance, my gut feeling would be to hook into theme_registry_alter().
when you're looking at a views page, you have access to piles of information here, as well as the page.tpl.php paths/files. as such i would do something like:
function modulejustforalteration_theme_registry_alter(&$variables) {
if (isset($variables['views_ui_list_views']) ) {
// not sure if that's the best index to test for "views" but i imagine it'll work
// as well as others
$variables['page']['template'] = 'override_page';
}
}
this should allow you to use a "override_page.tpl.php" template in your current theme in which you can remove anything you want (as my first answer above).
a few things:
as i said, not sure if views_ui_list_views is always available to check against, but it sounds like it should be set if we're looking at a view
you can alter the theme paths of the page array if you prefer (to change the location of where drupal will look for page.tpl.php, instead of renaming it altogether)
there doesn't appear to be any identifiers for this specific view, so this method might be an "all views will be stripped" approach. if you need to strip the page.tpl.php for a specific view only, perhaps hooking into template_preprocess_page() might be a better idea.
I like the Drupal module. BUt, here's another way.
copy page.tpl.php in your theme folder to a new file called page-VIEWNAME.tpl.php, where VIEWNAME is the machine-readible name of the view.
Then edit page-VIEWNAME.tpl.php to suit.
There is also http://drupal.org/project/pagearray which is a general solution...
Also, #Scott Evernden's solution is a cross site scripting (XSS) security hole. Don't do that. Read the documentation on drupal.org about how to Handle Text in a Secure Fashion http://drupal.org/node/28984
A simple way to display content of a special content-type you wish to display without all the stuff of the page.tpl.php:
Add the following snippet to your template.php file:
function mytheme_preprocess_page(&$vars) {
if ($vars['node'] && arg(2) != 'edit') {
$vars['template_files'][] = 'page-nodetype-'. $vars['node']->type;
}
}
Add a page-nodetype-examplecontenttype.tpl.php to your theme, like your page.tpl.php but without the stuff you don't want to display and with print $content in the body.
If I understand your question, you want to have nodes which contain all the HTML for a page, from DOCTYPE to </HTML>. What I would do is create a content type for those nodes -- "fullhtml" as its machine-readable name -- and then create a node template for it called node-fullhtml.tpl.php. You can't just dump the node's contents, as they've been HTML-sanitized. node.fullhtml.tpl.php would literally be just this:
echo htmlspecialchars_decode($content);
Then you'll need a way to override the standard page.tpl.php. I think what you could do is at the top of your page.tpl.php check the $node's content type, and bail out if it's fullhtml. Or, set a global variable in node-fullhtml.tpl.php that page.tpl.php would check for.
I'm no Drupal expert, but that's how I'd do it. I'm talking off the cuff, so watch for devils in the details.
I see you have already gone and made yourself a module, so this may no longer help, but it is fairly easy to get a view to expose an rss feed, which might be an easier way of getting at the content, especially if you want to include it on a different site.
On D7 you can use menu_execute_active_handler
$build = menu_execute_active_handler('user', FALSE);
return render($build);
jeroen's answer was what did for me after playing with it. I have a Drupal 7 site.
First of all make sure you replace MY_THEME with your theme name. Yes it is obvious but most newbies miss this.
I actually already had a function MY_THEME_preprocess_page(&$variables) {. Do not recreate the function then but add this code at the end of the function before you close it with }.
if (isset($_GET['response_type']) && $_GET['response_type'] == 'embed') {
$variables['theme_hook_suggestions'][] = 'page__embed';
}
My function used $vars not $variables, so I had to update that as well. Again obvious if you think look for it.
My first answered allowed me to only display the node when I called it up in a web browser. However the ultimate goal of this is to embed the drupal node in an 3rd party site using iframe.
Since the release of Drupal Core 7.50 iframe is by default blocked to prevent Clickjacking
To get only the node to successfully embed in a 3rd party site you also need to override the x-frame default setting. Everything started working after I added the following in template.php
function MY_THEME_page_alter($page) {
if (isset($_GET['response_type']) && $_GET['response_type'] == 'embed') {
header_remove('X-Frame-Options');
}
}
