What I am trying to do is to get an Id from a folder number.
Both my Id and my folder number (folder number is unique) are in the same controller.
I get the folder number from a text input and I then need to redirect the user to a page /Id.
My question is how should I handle it ?
Do I need to create a method getIdFromFolderNumber() in my controller and then call this function in my JS function ?
Or maybe do I need to do everything in a JS function (I know I need a JS function since I will use an AJAX request to redirect my user and to get the value from the input).
I don't need the code or anything, I just want to know the method I need to use to understand how to do it. I've started working on a very big project and since I am a junior developer I am a bit lost.
Thank you for your help.
You don't need any JS to achieve that. It's a simple form and redirection.
Once your form which gives you the number is submitted :
$number = $form->get('number')->getData();
Then you got your criteria for your doctrine request :
$id = $yourEntityRepository->findBy(['number' => $number)])->getId();
Now you have your ID for the redirection :
return $this->redirectToRoute('entity_show', ['id' => $id]);
IS that what you were looking for ?
Note : you don't need to store $number and $id as variables. It was only to make it clear. You can replace them by the actual requests where it's needed.

but does anyone know how to make an input work as such, for example I am making a chatbot with this pyscript method and I have this simple problem, I cannot make the entered text be saved in the variable to do this process, I am new to this and it would help me, here in the python code fragment you can see a def with the name get_response(user_input) that method is the one that is in charge of generating everything but it gives me an error when executing it since the "user_input" does not has no data entered is the only error I have and I don't know how to fix it so I can read it in html
def get_response(user_input):
split_message = re.split(r'\s|[,:;.?!-_]\s*', user_input.lower())
response = check_all_messages(split_message)
return response
It has document element selectors, you can normally use an input(text).
Use the following as:
<input type=“text” id=“my-txt-field” />
.
.
.
user_input = Element('my-txt-field').element.value;
print(user_input)
I am firt time trying DELETE method with fetch in javascript. I just want to read the sent data from my fetch in php. I am doing this:
... in js
fetch(this.url+"?deleteID="+ID,{method:'DELETE'})
... in php
if(($_SERVER['REQUEST_METHOD'] == 'DELETE')){
$id= $_GET["deleteID"];
}
but it is failing and I do not know why. The definition of $_GET is "An associative array of variables passed to the current script via the URL parameters" and I am passing deleteID as a param or not ? (When the method is GET, this works)
Thanks for explanation.
Im sorry, this works... I was using wrong URL
I have a express route;
router.get('/uni/:queryst', function (req, res) {
var choice = req.params.queryst);}
Where basically I use the queryst value from the URL to use it to query something in my database. On the front end, I need to have an input field where the user types the choice and hits submit and then it translates to something like /uni/valuehere on the browser and sending GET to express where it gets caught by the router I wrote above. I don't know how can I make the input field of HTML turn into a URL of the format /uni/valuehere .
As for testing the code initially I was directly typing the URL manually with the value I intended to verify to check if the data passed. Well, users are not going to type URL's directly to search, they will need a form and that is what I can't get my head around to how to turn the input field into a URL in a format /uni/WhateverTheUserHasTypedInTheFieldShouldAppearHere
Thanks in advance for the help. I am self learning the MEAN stack and have come a long way. I need support of experienced developers as I am currently stuck here.
While sending the request write (in controller):
$http.get('/uni/'+queryst).success(function(response){
// Write code using response
});
While on the server side write:
$http.get('/uni/:queryst',function(req,res){
var choice= req.params.queryst
// Code ....
});
Here's an example of a page from the API I'm working with:
http://www.easports.com/fifa/football-club/apps/proclubs/PS4/CHIP%20IT%20BRO
On this page almost all of the data is being loaded in via GET calls.
Here are 3 of the main calls that I'm interested in:
http://www.easports.com/iframe/fifa14proclubs/api/platforms/PS4/clubs/66232/members
http://www.easports.com/iframe/fifa14proclubs/api/platforms/PS4/clubs/66232/info
http://www.easports.com/iframe/fifa14proclubs/api/platforms/PS4/clubs/66232/stats
You'll notice that there is one thing in common with these calls, and that is the number after the "clubs/" part of the URL. In this case, it's 66232. That is the ID of the club. Basically, if I have this ID, I can get all of the information I need from this API.
The problem:
The only way I can grab this ID is if I manually inspect the page myself via Firebug. On my website, users will need to be able to automatically register their clubs. I want them to be able to provide the URL to their club page, eg.:
http://www.easports.com/fifa/football-club/apps/proclubs/PS4/CHIP%20IT%20BRO
Is there any way I can grab the ID in these ajax calls just by having the URL of the page? I don't even need the info that is returned from these calls, I just need the club ID that is part of the URL of these calls, eg.:
www.easports.com/iframe/fifa14proclubs/api/platforms/PS4/clubs/66232/members
I can just use some string functions to grab the ID after the "clubs/" substring up until the next "/".
I've been looking all over for a solution but can't seem to find what I'm looking for.
Thanks in advance. :)
EDIT:
Why is my question getting downvoted like crazy? I think I explained it pretty well. :/
Try using PHP's DOMDocument:
// clubId.php
<?php
$dom = new DOMDocument; #$dom->loadHTMLFile('http://www.easports.com/fifa/football-club/apps/proclubs/PS4/CHIP IT BRO');
$bod = $dom->getElementsByTagName('body');
if($bod = $bod->item(0)){
$cid = $bod->getAttribute('club-id');
$ea = 'http://www.easports.com/iframe/fifa14proclubs/api/platforms/PS4/clubs/'.$cid;
$members = #file_get_contents("$ea/memebers");
$info = #file_get_contents("$ea/info");
$stats = #file_get_contents("$ea/stats");
}
else{
echo 'Sorry, the Page is Probably Blocked!';
}
?>
Now you can echo $members, and the like, into HTML that creates JavaScript. Of course, you should have a firm grasp on JavaScript Objects and Arrays.
IT DOES APPEAR BLOCKED THOUGH!!!
I am a real noob when it comes to javascript/ajax, so any help will be very appreciated.
In reference to this question:
Updating a MySql database using PHP via an onClick javascript function
But mainly concerned with the answer left by Phill Sacre. I am wondering if someone could elaborate on how we are(if we can?) passing values/data through his example, using jquery.
The code example left by him is as follows:
function updateScore(answer, correct) {
if (answer == correct) {
$.post('updatescore.php');
}
}
...
<a onclick="updateScore(this, correct)" ...> </a>
Say for example, we are wanting to pass any number of values to the database with php, could someone give me a snippet example of what is required in the javascript function? Or elaborate on what is posted above please?
Thanks again all.
The simplest example I can think of is this. Make your AJAX call in your if block like this:
$.get('updatescore.php', {'score': '222'}, function(d) {
alert('Hello from PHP: ' + d);
});
On your "updatescore.php" script, just do that: update the score. And return a plain text stating wether the update operation was successful or not.
Good luck.
P.S.: You could also use POST instead of GET.
What you would do is on the php server side have a page lets say its update.php. This page will be visited by your javascript in an Ajax request, take the request and put it in a database.
The php might look something like this:
<?php
mysql_connect(...)
mysql_query("INSERT INTO table
(score) VALUES('$_GET["score"]') ")
Your javascript would simply preform an ajax request on update.php and send it the variables as get value "score".
Phil is not passing any values to the script. He's simply sending a request to the script which most likely contains logic to 'update' the score. A savvy person taking his test though could simply look at the HTML source and see the answer by checking to see what the anchor is doing.
To further nitpick about his solution, a set of radio buttons should be used, and within the form, a button or some sort of clickable element should be used to send the values to the server via an ajax request, and the values sent to the server can be analyzed and the status of the answer sent back to the page.
Since you're using jQuery, the code can be made unobtrusive as seen in the following example:
$('#submit_answer').click(function() {
var answer = 'blah' // With blah being the value of the radio button
$.get('updatescore.php',
{'value': answer},
function(d) {
alert('Your answer is: ' + d') // Where d is the string 'incorrect' or 'correct'
}
});
Enjoy.
