i have a page tweety which contains a single form where a user enters a word in a textbox and in on pressing search the tweets corresponding to that word are displayed.
I want to use hook_nodeapi to add these tweets but i want those things only on a specific url not all the page(or any node type).
I ll use hook_menu to make that page and display the form for the search. What should i do after that. I knw the twiiter api to fetch the tweets so that is not a issue.
I think what you're attempting to do is have the tweets load on a predetermined page by passing the posted information to the page, is that correct?
There's a couple ways I think you could accomplish this - easiest, and not requiring any complex ahah scripting would be to take the word they enter and generate a path which you could then use to make the page in question.
Make a menu Item:
function mymodule_menu() {
$items = array();
$items['mymodule/tweets/%'] = array(
'title' => t('Tweets about' . check_plain(array(2))),
'page callback' => 'mymodule_tweet_display',
'page arguments' => array(2) // This is the 3rd argument in the path, the %
);
}
In your form, you'll need to send the user to this path so add to your hook_submit function:
$tweet_topic = $form_state['values']['your-field-name-here'];
drupal_goto('mymodule/tweets/' . $tweet_topic);
Now add your page module, this is where you can use the twitter api:
function mymodule_tweet_display($tweet_topic) {
$tweet_topic = check_plain($tweet_topic);
// Use this variable in your Twitter API call
// ...
// Make sure you assign your display content to the page by returning a variable
return $page;
}

I am using Yii2 with Pjax for index/gridview listing. using pjax pagination , search all working fine without postback to server.
My problem starts now,
suppose i am on page number 2, i have clicked on edit record of that 2nd page list, i reach to update view, i have done changes and saved, now i am redirected to view , now i clicked on index link from breadcrumbs.
i want to reach to page number 2 of index rather then 1st page.
Traditional process for this is get refereeing page params an append that in breadcrumbs.
But is there any simple approach to this problem where i can write few lines of code and its applied to every where in backend?
Thanks for reading.
For remembering grid filter, pages i use yii2-grid-view-state
If you need to store page only, isn't it quite easy to pass page param into your view url (<model/view>) like <model>/view?id=<id>&page=<page>?
in your index.php view, edit your ActionColumn as follow:
[
'class' => 'yii\grid\ActionColumn',
'urlCreator' => function ($action, $model, $key, $index) {
return \yii\helpers\Url::to([$action, 'id' => $model->id, 'page' => Yii::$app->request->getQueryParam('page', null)]);
},
],
As you can see, I'm getting page param from request url and pass it to models' action buttons (to all buttons, but in your question it would be enough for view button of course)
And when you click to view model, in our Controller we need to get that page value and pass it to our view.php view (in order to place it in breadcrumbs).
Our ModelController:
public function actionView($id, $page = null)
{
return $this->render('view', [
'model' => $this->findModel($id),
'page' => $page,
]);
}
And finally view.php view will get the page value, and populate the index url (if not null):
/* #var $page int */
$this->title = $model->name;
$this->params['breadcrumbs'][] = ['label' => 'Index', 'url' => ['index', 'page' => $page]];
So when you press the Index breadcrumb, it will open the page, where you entered from.
Some advantages againts session implementation (#user1764431 solution):
Each of your tab can return to it's own last page
Simple and stupid solution
Some disadvantages:
If you need to store some filter params, url could stretch very long
Just add following Code in every controller of actionIndex() rest all things will take care
$searchModel = new CentervideosSearch();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
/*Code insertion block begin*/
$params = Yii::$app->request->queryParams;
if (count($params) <= 1)
{
$params = Yii::$app->session['customerparams'];
if(isset(Yii::$app->session['customerparams']['page']))
$_GET['page'] = Yii::$app->session['customerparams']['page'];
if(isset(Yii::$app->session['customerparams']['per-page']))
$_GET['per-page'] = Yii::$app->session['customerparams']['per-page'];
}
else
{
Yii::$app->session['customerparams'] = $params;
}
$dataProvider = $searchModel->search($params);
/*Code insertion block Ends*/
I'm trying to use nightmare, in node js to click on links based on the text inside the anchor text of the link.
Here's some example code:
var Nightmare = require('nightmare');
var nightmare = Nightmare({show: true})
nightmare
.goto('https://www.wikipedia.org/')
.inject('js', 'C:/users/myname/desktop/nodejs/node_modules/jquery/dist/jquery.js')
.wait(500)
var selector = 'a';
nightmare
.evaluate(function (selector) {
// now we're executing inside the browser scope.
return document.querySelector(selector).innerText;
}, selector) // <-- that's how you pass parameters from Node scope to browser scope
.end()
.then(function(result) {
console.log(result)
})
I'm really unclear on why the inner text of all tags are not returning? I thought I could maybe do an if statement in the .evalution method, so that it would restrict the link to be clicked on to "English" for instance.
Any idea how to click on links based on the link text?
As far as I know, there is no way to select a DOM element solely on what it contains. You'll either need to select all of the anchors (like you're doing now) and filter to what you want based on innerText then issue click events directly, or you could inject jQuery and use :contains and $.click() to issue the click.
Also, if you want all of the text from the tags, you'll likely want to use document.querySelectorAll().
As an example to get all of the text:
.evaluate(function (selector) {
return document.querySelectorAll(selector)
.map(element => element.innerText);
}, selector)
EDIT: I'm not looking for Facebook APIs! I'm simply using Facebook as an example. I intend to get my browser to perform actions on different websites that likely have no APIs.
Let's say I wish to create a program that will log into Facebook, lookup my friends list, visit each one of their profiles, extract the date + text of each post and write this to a file.
I have an idea how the algorithm should work. But I have absolutely no clue how to interface my code with the browser itself.
Now I'm a Java programmer, so I would very much imagine the pesudo code in Java would be to create a Browser Object then convert the current page's contents to HTML code so that the data can be parsed. I provided an example code below of what I think it ought to look like.
However is this the right way that I should be doing it? If it is, then where can I find a web browser object? Are there any parsers I can use to 'read' the content? How do I get it to execute javascript such as clicking on a 'Like' button?
Or are there other ways to do it? Is there a GUI version and then I can simply command the program to go to X/Y pixel position and click on something. Or is there a way to write the code directly inside my FireFox and run it from there?
I really have no clue how to go about doing this. Any help would be greatly appreciated! Thanks!
Browser browser = new Browser();
browser.goToUrl("http://facebook.com");
//Retrieve page in HTML format to parse
HtmlPage facebookCom = browser.toHtml();
//Set username & password
TextField username = facebookCom.getTextField("username");
TextField password = facebookCom.getTextField("password");
username.setText("user123");
password.setText("password123");
facebookCom.updateTextField("username", username);
facebookCom.updateTextField("password", password);
//Update HTML contents
browser.setHtml(facebookCom);
// Click the login button and wait for it to load
browser.getButton("login").click();
while (browser.isNotLoaded()) {
continue;
}
// Click the friends button and wait for it to load
browser.getButton("friends").click();
while (browser.isNotLoaded()) {
continue;
}
//Convert the current page (Friends List) into HTML code to parse
HtmlPage facebookFriends = browser.toHtml();
//Retrieve the data for each friend
ArrayList<XMLElement> friendList = facebookFriends.getXmlElementToArray("friend");
for (XMLElement friend : friendList) {
String id = friend.getId();
//Visit the friend's page
browser.goToUrl("http://facebook.com/" + id);
while (browser.isNotLoaded()) {
continue;
}
//Retrieve the data for each post
HtmlPage friendProfile = browser.toHtml();
ArrayList<XMLElement> friendPosts = friendProfile.getXmlElementToArray("post");
BufferedWriter writer = new BufferedWriter(new File("C:/Desktop/facebook/"+id));
//Write the date+text of every post to a text file
for (XMLElement post : friendPosts) {
String date = post.get("date");
String text = post.get("text");
String content = date + "\n" + text;
writer.append(content);
}
}
I think you are thinking about this the wrong way. You wouldn't really want to write a program to scrap the screen via the browser. It looks like you could take advantage of facebooks rest api and query for the data you are looking for. A link to get a users posts via rest api:
https://developers.facebook.com/docs/graph-api/reference/v2.6/user/feed
You could get their users id's from this endpoint:
https://developers.facebook.com/docs/graph-api/reference/friend-list/
Then plug the user ids into the first rest endpoint that was linked. Once you get your data coming back correctly via the rest api its fairly trivial to write that data out to a file.
I am building a CMS that supports a website which also contains an SMF forum (2.0.11). One of the modules in the CMS involves a "report" that tracks attendance. That data is queried to tables outside of smf, but in the same database. In addition to what it does now, I would also like for a post to be made in a specific board on the SMF forum containing the formatted content. As all of the posts are contained by the database, surely this is possible, but it seems there is more to it than a single row in a table.
To put it in the simplest code possible, below is what I want to happen when I click Submit on my page.
$title = "2015-03-04 - Attendance";
$author = "KGrimes";
$body = "Attendance was good.";
$SQL = "INSERT INTO smf_some_table (title, author, body) VALUES ($title, $author, $body)";
$result = mysqli_query($db_handle, $SQL);
Having dug through the smf DB tables and the post() and post2() functions, it seems there is more than one table involved when a post is made. Has anyone outlined this before?
I've looked into solutions such as the Custom Form Mod, but these forms and templates are not what I am looking for. I already have the data inputted and POST'ed to variables, I just need the right table(s) to INSERT it into so that it appears on the forum.
Thank you in advance for any help!

Code where you want to create post:
//Define variables
//msgOptions
$smf_subject = "Test Title";
//Handle & escape
$smf_subject = htmlspecialchars($smf_subject);
$smf_subject = quote_smart($smf_subject, $db_handle);
$smf_body = "This is a test.";
//Handle & escape
$smf_body = htmlspecialchars($smf_body);
$smf_body = quote_smart($smf_body, $db_handle);
//topicOptions
$smf_board = 54; //Any board id, found in URL
//posterOptions
$smf_id = 6; //any id, this is found as ID in memberlist
//SMF Post function
require_once('../../forums/SSI.php');
require_once('../../forums/Sources/Subs-Post.php');
//createPost($msgOptions, $topicOptions, $posterOptions);
// Create a post, either as new topic (id_topic = 0) or in an existing one.
// The input parameters of this function assume:
// - Strings have been escaped.
// - Integers have been cast to integer.
// - Mandatory parameters are set.
// Collect all parameters for the creation or modification of a post.
$msgOptions = array(
'subject' => $smf_subject,
'body' => $smf_body,
//'smileys_enabled' => !isset($_POST['ns']),
);
$topicOptions = array(
//'id' => empty($topic) ? 0 : $topic,
'board' => $smf_board,
'mark_as_read' => true,
);
$posterOptions = array(
'id' => $smf_id,
);
//Execute SMF post
createPost($msgOptions, $topicOptions, $posterOptions);
This will create the simplest of posts with title and body defined by you, along with location and who the author is. More parameters can be found in the SMF functions database for createPost. The SSI and Subs-Post.php includes must be the original directly, copying them over doesn't do the trick.
I'm trying to submit a drupal 6 form PIA to a third party site for processesing, but after submitting the form, I need to redirect to a thank you page within my own site.
I've read this post - Drupal form submission to a 3rd party website
but i'm nor sure how to set up the redirect properly.
this is my code:
$form_state['#action'] = 'external site.com';
$form['#redirect'] = 'thankyou.com';
thanks
Make sure the redirect is the last step. Something like this:
function my_module_form {
$form['#action'] = 'some.external.site';
# Store the redirect in a value element, maybe we need some data
# which are passed to the form, like a user ID, node ID etc.
# So lets store the link in a value element
$form['redirect_link'] = array(
'#type' => 'value',
'#value' => url('some.redirect.page'),
);
}
function my_module_form_validate ($form, &$form_state) {
# Do some validation stuff...
}
function my_module_form_submit($form, &$form_state) {
# show some confirmation message...
drupal_set_message(t('Successfully sent your data into space.'));
# And finally the redirect...
# The 'redirect_link' value was passed internally, without being sent
# to the browser so we can safely use it.
$form_state['redirect'] = $form_state['values']['redirect_link']
}
Redirect property is also set in $form_state.
$form_state['redirect'] = 'some.com';
Since I'm only trying to send informtaion to a third party and not actually redirecting the page after form submission to a third party site.
I got the right answers tot he wrong question.
This is what I ended up using that worked for me:
$url = 'http://thirdpartyurl';
$headers = array('Content-Type' => 'application/x-www-form-urlencoded');
$data = drupal_query_string_encode($pass_the_form_info);
drupal_http_request($url, $headers, 'POST', $data);
