I am having hard time sending some JSON data as a checkbox value. When I tried to send the JSON value, I receive only the first word as a value i.e '"{", but I need the whole chunk value. What may be the possible solutions ?
value to be send as checkbox value:
{
"audio_uri"=>
"http://testing.s3.amazonaws.com/N7jcpdkaVH-part_137768534157151.mp3",
"audio_begin_time"=>"80",
"audio_length"=>"9540",
"video_title"=>"apple_boy_cat",
"text"=>"heoolo \r\n\r\n\r\nI \r\n\r\nAm \r\n\r\n please help me..."
}
I would be grateful if anyone help me resolving this problem.
Try html escaping the json data to be sent.
For rails if your data hash is in data variable, you might wanna do CGI::escape(data.to_json) for checkbox value and when received in server side, just parse the data.

I have a problem and I don't quite know how to deal with it. It must be a common problem, but I didn't find a good answer yet.
I'm coding a MEAN stack app, using Mongoose, and the problem I have is with the dates format when changing the language in my app.
The scenario is: The user can insert some data that has a Date field, for example their birthday. That field is then sent to mongoose in a specific format (yyyy-MM-dd) and it gets stored correctly in a Date field in mongoose. When the user searches for the data stored, I have an $http get request that get back the data in JSON format. Right before the data is send from the server, I have this in the JSON:
{datetime: '2015-11-13T20:00:00.000Z'}
And send it from nodejs like this:
return res.status(201).send(obj);
And when the Angular gets it, depending on the language I'm using in that moment, it resolves to a Date or an Invalid date. If the language I'm using is English, the resulting JSON has a valid Date in that field. If I change it to Spanish for example, then it results into an Invalid date field.
The code in Angular is this:
$http.get(url).then(function (result) {
//here the result.data may have an Invalid Date field
deferred.resolve(result.data);
}, function (error) {
deferred.reject(error);
});
I set the language in my app with the help of angular-translate, and I use angular-i18n and momentjs also.
I've read on this and here https://docs.angularjs.org/api/ng/service/$http it say that
If JSON response is detected, deserialize it using a JSON parser.
I understand that the default parser detects the Spanish i18n and tries to parse the date as yyyy-dd-MM, and obviously gets an Invalid Date.
The question here is: How can I explicitly set all the dates parsed in Angular, to follow a specific format, like yyyy-MM-dd, regardless of the i18n used? I've seen this solution already, but doesn't work for me: http://aboutcode.net/2013/07/27/json-date-parsing-angularjs.html
Is there a better way to handle all this? Maybe store the dates in Mongo not as Date fields, but like Strings, using the JS getTime() function?
This last method means that I would have to change all the dates in my app. It's a lot more work, but the result will be more standard, right?
Thank you!
I am using stringify and json is getting formatted and in alert it is coming.But in actual link it is not displaying. When I checked in console error was coming as "duplicates are not allowed in ng-repeat for the key".
Can anyone tell how to allow duplicates in ng-repeat so that formatted json will be printed.
Add 'track by $index' to the repeater.
https://docs.angularjs.org/error/ngRepeat/dupes
I have a test that I need to automate using Java:
Do a GET to check if a specific value exist in a JSON response, if exist do a PUT request with a new value
Do a GET again and search for the updated value, if found to the PUT with the original value.
Then do the GET to check if the original value exist.
Please help. Any response will be appreciated.
Thank you
I have created Wordpress custom fields through functions.php. My code works fine, and I've few input fields and some checkboxes.
Problem is when I save post, even if I don't put content inside my form, these rows are created in DB. I'd like to do some kind of php check and avoid creation of row in DB if field content is not saved.
I tried several ways, but in most cases it would result in incorrect behaviors of checkboxes for example.
Full code is here: http://pastebin.com/embed_js.php?i=Vvnseiep
I'd appreciate your help in this matter. I'm not very experienced.
Thanks!
Here Validation part comes into play. Why cant you use Javascript to validate your input in the client environment itself and then allowing it to hit the db.
Name all of the checkboxes the same(name="meta_box_check[]"). They must still have different ID's. When the form is posted you will be given an array of values that were checked in $_POST['meta_box_check']. You can then check if the array is empty. You can also save the checkbox data as JSON data. This isn't always good practice, but will only use one data row to save any and all checkbox values.
<?php
if(!empty($_POST['meta_box_check']))
{
//process your data and save it
update_post_meta($post_id, 'meta_features_checklist', json_encode($_POST['meta_box_check']));
}
?>
This is a basic example and make sure you do some data validating before saving.
I want something like this:
link
GET and 2x POST in hyperlink. How can I do that? Nothing wants to work
I have a GET array in PHP and I want to generate a link which leads to the correct url to give me those GET variables.
You can't have 2 GET variables with the same name. You can arrange them into an array as follows:
link
Just for clarification, this is still a GET request, links cannot normally produce a POST request, nor you should try to achieve that not-normally.
EDIT: To answer OP's calrification.
If you have a $_GET array, and you want to generate a link to get you there, you can use http_build_query()
I don't think you understand what GET and POST means in the HTTP world. Any items you put on a query string of a URL are GET parameters, you can't have 2 with the same name. POST parameters are sent as a part of the request, not as a query string on the URL.
GET and POST are http operations.
Sending values by using the ? as a separator in the url is different but related. eg:
foo.com/page.php?val1=1&val2=2
The values are called Query String values.
For GET operations, values are sent as a query string values. For POST operations, the values are sent in the body of the POST request. This is why POST must be used when a lot of data is being sent to the server. (Query strings have a maximum length, HTTP requests do not.)
You can do a POST operation to a url that includes query string values. This is more common with Ajax requests but can be done in a form as well. Just set the action url to something like index.php?val1=1&val2=2 the form's (additional) values will be sent as the http body. Remember to set method="post" in the form.
Note that you will need to create the query string yourself in this example, including escaping it properly.
Repeating value names in the query string values
Usually this causes both values to be sent, but the server overwrites the variable and ends up only presenting the last one to the client software.
So if you use a url such as
<a href="http://localhost/index.php?get=abc&post=cde&post=efg">
// It will be decoded by php and most server-side frameworks as
set get to abc
set post to cde
set post to efg
Result: 2 variables, get and post
There is nothing in the HTTP standard that says you can't send two query string params with the same name. However, you won't be able to use $_GET to retrieve these values; $_GET will pick up the last one. Instead, you'll have to manually parse $_SERVER['QUERY_STRING']. It's not that hard and I've done it a number of times when PHP has to handle a URL pattern generated by a third-party tool. If you're feeling really fancy you can have your query-string parse routine generate a $_GET member as an array if more than one instance of that member is encountered.
