I am a noob facebook app developer and I would be very grateful for a little hand-holding getting started by professionals. I created a very simple app. It's only one file (index.php) and it has an html form that posts a value back to index.php to display. It worked before I added a "share to wall" request to the authentication. Now (I guess) there is a redirection before realoading the index.php, so it gets no $_POST value and it doesn't display the entered value. I would be very grateful if somebody would actually check out my app and its code and tell me how to fix it. (I think it's important to mention that it requests permission to post to the user's wall, but actually it doesn't post anything to the wall. I want to add that functionality later.) Here is the app:
https://apps.facebook.com/webszebb/
And here is the code (screenshot):

Thanks.
For the sake of simplicity I'd suggest doing something like:
<html header stuff>
<?php
...snip...
if ($_REQUEST['do'] == 'whatever the action is, i.e: action="?foo" would be foo here') {
print('Your previous number was ' . $_POST['my_number']);
} else {
print('form');
}
?>
But to answer your question I'm assuming the $fb->api('/me') probably redirects you.

Currently I have my project running as welcomFile the index.html file. This file takes me to an authentication process. The case is that I need to access one of my views but without performing this authentication, that is, I don't want to go through this index.html. To do so, I created another html (index_new.html). Even if I run this last one it always redirects me to the index.html, I don't know if it has to do with how the neo-app.json file is configured. I tried to put in the index.html that if it arrived a parameter in the url to be directed to the index_new.html but without success, it says that the page does not exist. This is what I tried:
<script>
const queryString = window.location.search;
const urlParams = new URLSearchParams(queryString);
window.location.search = urlParams.toString();
const con = urlParams.get('con');
if (con !== ""){
window.open("/index_new.html", "_self");
}
</script>
The only way I have managed to load the path I want is to run the program, it goes to the index.html and once it has loaded, I change the path to the index_new.html/viewthatIwanttoshow and it shows up. Is there any way to run the new index_new.html without having to run the old one?
I also think it's because of the manifest, because from the index_new.html I do it like this, just like in the index.html:
……
<script id="sap-ui-bootstrap>
…
data-sap-ui-resourceroots='{"app.hello”: “./“}’
…
</script>
</head>
<body class="sapUiBody">
<div data-sap-ui-component data-name="app.hello” data-id="container" data-settings='{"id" : “hello”}’ style="height: 100%"></div>
</body>
Maybe I should change the path here but I don't know which one or how to configure it in the manifest.json.
Maybe my question is not clear, if you have any questions please let me know.
My neo-app.json:
"welcomeFile": "/webapp/index.html",
My manifest.json:
"sap.app": {
"id": “app.hello”,
"type": "application",
I can't / don't want to give you a direct answer on your question. But I would like to mention to think about the concept you are going for.
I don't really understand why you want to load different index.html files. It's pretty far away from a best practice scenario - at least with the information I have out of your post.
When we are talking about authentication, mostly you save a token in cookies / browser storage. Then you can check if you are authenticated. If so, use the UI5 router. In every page you want to, you can check for valid authentication / authorization and redirect again to a login page, if you are not.
IMO you shouldn't use two different index.html sites.
I hope this help you to find another way to solve it.
so I'm trying to use meta reload to update my website (using the code below) and I was wondering if it was possible to make it reload once after opening the page.
<meta http-equiv="refresh" content="3" >
Why, because looking at a website that refreshes every 3 seconds is really annoying to look at. If you can help, thank you.
#David's comment (original post)
To store values without files and within the webpage. I suggest you encrypt the data because it is visible in the developers console 'local storage'
function holdArray(array){
localStorage.setItem("holdArray", array);
return true;
}
function releaseArray(){
if(localStorage.hasOwnProperty('holdArray')){
return localStorage.getItem("holdArray");
}
}
Set data
holdArray(JSON.stringify(yourvariable));
Get data
let storage = releaseArray();
All I had to do to make it update once when the page was loaded was change index.html to index.php
Thank you with all the help you guys gave me, but this is all I ended up needing to do. I still very much appreciate the effort though.
I am looking for help for the following scenario:
I have a website1.com. I would like website1.com to be like a presentation page. I want every person who has seen the page to be redirected automatically to website2.com.
Another way to look at it:
Lets say the page on website1.com contains information, which would be irrelevant for the person, who has already seen it, therefore I want them to be redirect from the page to website2.com cause then i don't loose the visitor, since I own both of those sites.
From the prespective of the visitor:
I land on a website, which I have not visited yet, website1.com. However, if I have already been to website1.com in the past ( cookie registers it ) , then i am redirected to website2.com
Hope how i broke it down is clear for everybody.
Thank you in advance for the help.
If you are using PHP, you could do it that way at the begining of your page:
<?php
if (!isset($_COOKIE['myCookie'])){
setcookie('myCookie', true, time() + (86400 * 30));
}
else{
header('Location: http://www.website2.com');
}
?>
If you are not using PHP, your serverside language surely have a way to set cookie and the logic will be the same. Hope it helped
I've got a product that embeds into websites similarly to Paypal (customers add my button to their website, users click on this button and once the service is complete I redirect them back to the original website).
I'd like to demo my technology to customers without actually modifying their live website. To that end, is it possible to configure http://stackoverflow.myserver.com/ so it mirrors http://www.stackoverflow.com/ while seamlessly injecting my button?
Meaning, I want to demo the experience of using my button on the live website without actually re-hosting the customer's database on my server.
I know there are security concerns here, so feel free to mention them so long as we meet the requirements. I do not need to demo this for website that uses HTTPS.
More specifically, I would like to demonstrate the idea of financial bounties on Stackoverflow questions by injecting a Paypal button into the page. How would I demo this off http://stackoverflow.myserver.com/ without modifying https://stackoverflow.com/?
REQUEST TO REOPEN: I have reworded the question to be more specific per your request. If you still believe it is too broad, please help me understand your reasoning by posting a comment below.
UPDATE: I posted a follow-up challenge at How to rewrite URLs referenced by Javascript code?
UPDATE2: I discarded the idea of bookmarklets and Greasemonkey because they require customer-side installation/modification. We need to make the process as seamless as possible, otherwise many of get turned off by the process and won't let us pitch.
I would suggest to create a proxy using a HTTP handler.
In the ProcessRequest you can do a HttpWebRequest to get the content on the other side, alter it and return the adjusted html to the browser. You can rewrite the urls inside to allow the loading of images, etc from the original source.
public void ProcessRequest(HttpContext context)
{
// get the content using HttpWebRequest
string html = ...
// alter it
// write back the adjusted html
context.Response.Write(html);
}
If you're demoing on the client-side and looking to just hack it in quickly, you could pull it off with some jQuery. I slapped the button after the SO logo just for a demo. You could type this into your console:
$('head').append('<script src="https://www.paypalobjects.com/js/external/dg.js" type="text/javascript"></script>')
$('#hlogo').append('<form action="https://www.sandbox.paypal.com/webapps/adaptivepayment/flow/pay" target="PPDGFrame" class="standard"><label for="buy">Buy Now:</label><input type="image" id="submitBtn" value="Pay with PayPal" src="https://www.paypalobjects.com/en_US/i/btn/btn_paynowCC_LG.gif"><input id="type" type="hidden" name="expType" value="light"><input id="paykey" type="hidden" name="paykey" value="insert_pay_key">')
var embeddedPPFlow = new PAYPAL.apps.DGFlow({trigger: 'submitBtn'});
Now, I'm not sure if I did something wrong or not because I got this error on the last part:
Expected 'none' or URL but found 'alpha('. Error in parsing value for 'filter'. Declaration dropped.
But at any rate if you are demoing you could just do this, maybe as a plan B. (You could also write a userscript for this so you don't have to open the console, I guess?)
After playing with this for a very long time I ended up doing the following:
Rewrite the HTML and JS files on the fly. All other resources are hosted by the original website.
For HTML files, inject a <base> tag, pointing to the website being redirected. This will cause the browser to automatically redirect relative links (in the HTML file, CSS files, and even Flash!) to the original website.
For the JS files, apply a regular expression to patch specific sections of code that point to the wrote URL. I load up the redirected page in a browser, look for broken links, and figure out which section of JS needs to be patched to correct the problem.
This sounds a lot harder than it actually is. On average, patching each page takes less than 5 minutes of work.
The big discovery was the <base> tag! It corrected the vast majority of links on my behalf.
I am at a bit of loss of knowledge and honestly don't know what to search for. What I need to be able to do is determine what content to show on a webpage that way when I refresh it will not reset everything. For example, if someone clicks on the messages tab I want the browser to know when it refreshes, that is the tab to stay on. I believe this is done through url encoding but I am not sure. Any help would be AWESOME! Thanks fellow coders.
MORE INFO: I have 2 buttons on a page. One is named "home" and when I click it I want the content of the home page to appear in a box named "info-main". I am doing this with ajax requests. When I click on "edit profile", I want the content in div id "info-main" to be replaced with the edit profile information that is retrieved via ajax as well. I need to figure out how if someone refreshes the page... I want it to stay showing the edit profile information rather then going back to the default of "home" content.
MORE INFO(AGAIN)
I just had a great idea. When the page refreshes, I want it to load specific ajax code based on what the url encode is.
For example.... if the url is:
http://www.exampleurl.com/index.php?info=status-load
I want the browser to execute the ajax I have for retrieving status's.
OR
If the url is:
http://www.exampleurl.com/index.php?info=edit-prof
I want it to load the ajax code I have for retrieving profile edit info.
I really hope this helps. :/
The way I do it is I place a # before the link i.e. href="#messages"
Then I link a .js with this code.
$(function () {
var hash = location.hash
, hashPieces = hash.split('?')
, activeTab = $('[href=' + hashPieces[0] + ']');
activeTab && activeTab.tab('show');
});
I hope this helps
For referring an element on your page, you use a link with a hashtag.
For example, if you have a layout like this:
<div class="top-nav">
Home
Edit Profile
</div>
And you have a password edit form on your editProfile page, you can like to it like this:
Edit Profile
if you have a <form id="passwordChange"> on your editProfile.
