  • Placing PHP array values into a javascript array?

    - by Michael Harringon
    Is these a way i can loop through a PHP array and have the data outputted into a JavaScript array? For example, the JS script below will not work var mon_Loop = <?php echo $rowCount_Mon ?>; var mon_Events = new Array(); for(i = 0; i < mon_Loop; i++) { mon_Events[i] = <?php $divMon[i] ?> } I Know its because the "i" is not a php variable so therefore invalid inside the php section, but its just an way to show what i would like to achieve. The $rowCount variable count the number of rows and is then used to for the loop. Lets say, for example that I want to place the contents of the PHP array "$divMon[0]" into the javascript array mon_Events[0]. I know that i can do it manually, like below mon_Events[0] = <?php echo $divMon[0] ?> But i have lots of these and therefore need the loop, Is there some JS or PHP that could do this? Cheers.

  • Can I get a reference to a pending transaction from a SqlConnection object?

    - by Rune
    Hey, Suppose someone (other than me) writes the following code and compiles it into an assembly: using (SqlConnection conn = new SqlConnection(connString)) { conn.Open(); using (var transaction = conn.BeginTransaction()) { /* Update something in the database */ /* Then call any registered OnUpdate handlers */ InvokeOnUpdate(conn); transaction.Commit(); } } The call to InvokeOnUpdate(IDbConnection conn) calls out to an event handler that I can implement and register. Thus, in this handler I will have a reference to the IDbConnection object, but I won't have a reference to the pending transaction. Is there any way in which I can get a hold of the transaction? In my OnUpdate handler I want to execute something similar to the following: private void MyOnUpdateHandler(IDbConnection conn) { var cmd = conn.CreateCommand(); cmd.CommandText = someSQLString; cmd.CommandType = CommandType.Text; cmd.ExecuteNonQuery(); } However, the call to cmd.ExecuteNonQuery() throws an InvalidOperationException complaining that "ExecuteNonQuery requires the command to have a transaction when the connection assigned to the command is in a pending local transaction. The Transaction property of the command has not been initialized". Can I in any way enlist my SqlCommand cmd with the pending transaction? Can I retrieve a reference to the pending transaction from the IDbConnection object (I'd be happy to use reflection if necessary)?

  • C# - Class Type as Parameter in methods

    - by Claudio
    Hi guys, I'm using SQLite.cs wrapper for helping me with the database and I have this method for create XML from a table, that is working fine. public void GenerateInvoiceXML(string filePath) { var invoices = app.db.Table<Invoice>().ToList(); XmlSerializer serializer = new XmlSerializer( typeof(List<Invoice>) ); TextWriter writer = new StreamWriter(filePath); serializer.Serialize(writer,invoices); writer.Close(); } All tables that I have are defined like this: [Serializable] public class Invoice { [PrimaryKey, AutoIncrement] public int Id { get; set; } public string Supplier {get; set;} public string Date {get; set;} public string PaymentMethod {get; set;} public string Notes {get; set;} public Invoice(int newID) { Id = newID; } public Invoice() { } } But I want to change this method for something like this: public void GenerateInvoiceXML(string filePath, Type table) { var dataForXML = app.db.Table<table>().ToList(); XmlSerializer serializer = new XmlSerializer( typeof(List<table>) ); TextWriter writer = new StreamWriter(filePath); serializer.Serialize(writer,dataForXML); writer.Close(); } Does anybody have an idea how to do it? Kind Regards, Claudio

  • Linq duplicate removal with a twist

    - by Danthar
    I got a list that contains al the status items of each order. The problem that i have is that i need to remove all the items of which the status - logdate combination is not the highest. e.g var inputs = new List<StatusItem>(); //note that the 3th id is simply a modifier that adds that amount of secs //to the current datetime, to make testing easier inputs.Add(new StatusItem(123, 30, 1)); inputs.Add(new StatusItem(123, 40, 2)); inputs.Add(new StatusItem(123, 50, 3)); inputs.Add(new StatusItem(123, 40, 4)); inputs.Add(new StatusItem(123, 50, 5)); inputs.Add(new StatusItem(100, 20, 6)); inputs.Add(new StatusItem(100, 30, 7)); inputs.Add(new StatusItem(100, 20, 8)); inputs.Add(new StatusItem(100, 30, 9)); inputs.Add(new StatusItem(100, 40, 10)); inputs.Add(new StatusItem(100, 50, 11)); inputs.Add(new StatusItem(100, 40, 12)); var l = from i in inputs group i by i.internalId into cg select from s in cg group s by s.statusId into sg select sg.OrderByDescending(n => n.date).First() ; This creates a list that returnes me the following: order 123 status 30 date 4/9/2010 6:44:21 PM order 123 status 40 date 4/9/2010 6:44:24 PM order 123 status 50 date 4/9/2010 6:44:25 PM order 100 status 20 date 4/9/2010 6:44:28 PM order 100 status 30 date 4/9/2010 6:44:29 PM order 100 status 40 date 4/9/2010 6:44:32 PM order 100 status 50 date 4/9/2010 6:44:31 PM This is ALMOST correct. However that last line which has status 50 needs to be filtered out as well because it was overruled by status 40 in the historylist. U can tell by the fact that its date is lower then the "last" status-item with the status 40. I was hoping someone could give me some pointers because im stuck.

  • How do I add a comment to an image using jQuery

    - by marcamillion
    So I am trying to replicate Facebook's picture tagging functionality, and I have the functionality that onClick, a box is created and there is a comment box. Now the issue is that I want to be able to (without doing any back-end processing) take the input from the input field and add it in some form to the underlying image area that they have selected. I would also like to add a small image to that area, that shows that a comment is there. How do I do that? See the code below for what I have for the comment box: <script type="text/javascript"> $(function() { var tag_box = $("<div>").appendTo("body").css({ "width": "40px", "height":"40px", "border":"4px solid #000000", "position":"absolute", "display":"none", "padding":"15px" }); var comment_box = $("<form action='#'><input id='comment' type='text' name='comment' placeholder='Add comment'></form>").appendTo(tag_box).css({"position":"absolute"}); $("#image-wrapper").live('click', function(e){ tag_box.css({ "left": e.pageX - 40, "top": e.pageY - 40, "display": "block" }) .after(comment_box.css({ "left": e.pageX - 65, "top": e.pageY + 40 })); }); }); </script> Now...whenever the user presses enter, the info in the comment box is appended to the URL like so: .html?comment=comment value# Thanks

  • Will the following NHibernate interface mapping work?

    - by Ben Aston
    I'd like to program against interfaces when working with NHibernate due to type dependency issues within the solution I am working with. SO questions such as this indicate it is possible. I have an ILocation interface and a concrete Location type. Will the following work? HBM mapping: <class name="ILocation" abstract="true" table="ILocation"> <id name="Id" type="System.Guid" unsaved-value="00000000-0000-0000-0000-000000000000"> <column name="LocationId" /> <generator class="guid" /> </id> <union-subclass table="Location" name="Location"> <property name="Name" type="System.String"/> </union-subclass> </class> Detached criteria usage using the interface: var criteria = DetachedCriteria.For<ILocation>().Add(Restrictions.Eq("Name", "blah")); var locations = criteria.GetExecutableCriteria(UoW.Session).List<ILocation>(); Are there any issues with not using the hilo ID generator and/or with this approach in general?

  • Changing the color of dot depending from value on Morris js graph

    - by Michal Lipa
    Im rendering graph by morris js. Im using data from mysql database by JSON. Everything works fine, but I would like to add one more feature to the graph. (change dot color if there is something in buy action). My JSON: [{"longdate":"2014-08-20 18:20:01","price":"1620","action":"buy"},{"longdate":"2014-08-20 18:40:01","price":"1640","action":""},{"longdate":"2014-08-20 19:00:01","price":"1620","action":""}] So I would like to change dot color for values with buy action. My code for graph: $.getJSON('results.json', function(day_data) { Morris.Line({ element: 'graph', data: day_data, xkey: 'longdate', ykeys: ['price'], labels: ['Cena'], lineColors: lineColor, pointSize: 0, hoverCallback: function(index, options, content) { var date = "<b><font color='black'>Data: "+day_data[index]['longdate']+"</font></b><br>"; var param1 = "<font color='"+lineColor[0]+"'>Cena - "+day_data[index]['price']+"</font><br>"; return date+param1; }, xLabelFormat : function (x) { return changeDateFormat(x); } /*My TRIAL if(action == 'buy'){ pointSize: 4, lineColors: green, } */ }); }); So my code doesnt work, how can I make this working?

  • When dynamically adding nodes to DOM how to make browser repaint the background to avoid artefacts?

    - by Tim
    Given nested DIVs: <div id="outer" <div id = "inner" > <div id = "injectedcontent"> nodes are added to this DIV with </div> </div> </div> and this css: #outer {background-color: lightgrey; padding: 2em; width: 100%; height: 100%} #inner {background-color: white; width: 100%; height: 100%} and content injected in this manner: function injectContent(titleDivId, content){ var resultscontainer=document.getElementById('injectedcontent'); var titleDiv = document.getElementById(titleDivId); if (titleDiv == null) { titleDiv=document.createElement('div'); titleDiv.id=titleDivId; titleDiv.innerHTML += content; resultscontainer.appendChild(titleDiv); } else { titleDiv.innerHTML += content; } } the browsers do not redraw the outer DIV's background to accommodate the injected content. When I scroll the page (lots of text gets injected into the page -- it is a full-text search app) the lightgray background is painted right across the text, as shown in the attached image. Is there a way to cause the browser to recalculate page-depth after injecting content? Or is this problem related to this line: titleDiv.innerHTML += content; Is it better to add titleDiv's content a node at a time? I've recently seen respected people using innerHTML in this way, although postings from from several years ago discourage use of innerHTML. 1:

  • jQuery - Callback failing if there is no options parameter

    - by user249950
    Hi, I'm attempting to build a simple plugin like this (function($) { $.fn.gpSlideOut = function(options, callback) { // default options - these are used when no others are specified $.fn.gpSlideOut.defaults = { fadeToColour: "#ffffb3", fadeToColourSpeed: 500, slideUpSpeed: 400 }; // build main options before element iteration var o = $.extend({}, $.fn.gpSlideOut.defaults, options); this.each(function() { $(this) .animate({backgroundColor: o.fadeToColour},o.fadeToColourSpeed) .slideUp(o.SlideUpSpeed, function(){ if (typeof callback == 'function') { // make sure the callback is a function callback.call(this); // brings the scope to the callback } }); }); return this; }; // invoke the function we just created passing it the jQuery object })(jQuery); The confusion I'm having is that normally on jQuery plugins you can call something like this: $(this_moveable_item).gpSlideOut(function() { // Do stuff }); Without the options parameter, but it misses the callback if I do it like that so I have to always have var options = {} $(this_moveable_item).gpSlideOut(options, function() { // Do stuff }); Even if I only want to use the defaults. Is there anyway to make sure the callback function is called whether or not the options parameter is there? Cheers.

  • How to store a public key in a machine-level RSA key container

    - by Andrew Kimball
    I'm having a problem using a machine level RSA key container when storing only the public key of a public/private key pair. The following code creates a public/private pair and extracts the public key from that pair. The pair and the public key are stored in separate key containers. The keys are then obtained from those key containers at which point they should be the same as the keys going into the containers. The code works when CspProviderFlags.UseDefaultKeyContainer is specified for CspParameters.Flags (i.e. the key read back out from the PublicKey container is the same), but when CspProviderFlags.UseMachineKeyStore is specified for CspParameters.Flags the key read back from PublicKey is different. Why is the behaviour different, and what do I need to do differently to retrieve the public key from a machine-level RSA key container? var publicPrivateRsa = new RSACryptoServiceProvider(new CspParameters() { KeyContainerName = "PublicPrivateKey", Flags = CspProviderFlags.UseMachineKeyStore //Flags = CspProviderFlags.UseDefaultKeyContainer } ) { PersistKeyInCsp = true, }; var publicRsa = new RSACryptoServiceProvider(new CspParameters() { KeyContainerName = "PublicKey", Flags = CspProviderFlags.UseMachineKeyStore //Flags = CspProviderFlags.UseDefaultKeyContainer } ) { PersistKeyInCsp = true }; //Export the key. publicRsa.ImportParameters(publicPrivateRsa.ExportParameters(false)); Console.WriteLine(publicRsa.ToXmlString(false)); Console.WriteLine(publicPrivateRsa.ToXmlString(false)); //Dispose those two CSPs. using (publicRsa) { publicRsa.Clear(); } using (publicPrivateRsa) { publicRsa.Clear(); } publicPrivateRsa = new RSACryptoServiceProvider(new CspParameters() { KeyContainerName = "PublicPrivateKey", Flags = CspProviderFlags.UseMachineKeyStore //Flags = CspProviderFlags.UseDefaultKeyContainer } ); publicRsa = new RSACryptoServiceProvider(new CspParameters() { KeyContainerName = "PublicKey", Flags = CspProviderFlags.UseMachineKeyStore //Flags = CspProviderFlags.UseDefaultKeyContainer } ); Console.WriteLine(publicRsa.ToXmlString(false)); Console.WriteLine(publicPrivateRsa.ToXmlString(false)); using (publicRsa) { publicRsa.Clear(); } using (publicPrivateRsa) { publicRsa.Clear(); }

  • Literal ampersands in System.Uri query string

    - by Nathan Baulch
    I'm working on a client app that uses a restful service to look up companies by name. It's important that I'm able to include literal ampersands in my queries since this character is quite common in company names. However whenever I pass %26 (the URI escaped ampersand character) to System.Uri, it converts it back to a regular ampersand character! On closer inspection, the only two characters that aren't converted back are hash (%23) and percent (%25). Lets say I want to search for a company named "Pierce & Pierce": var endPoint = "http://localhost/companies?where=Name eq '{0}'"; var name = "Pierce & Pierce"; Console.WriteLine(new Uri(string.Format(endPoint, name))); Console.WriteLine(new Uri(string.Format(endPoint, Uri.EscapeUriString(name)))); Console.WriteLine(new Uri(string.Format(endPoint, Uri.EscapeDataString(name)))); All three of the above combinations return: http://localhost/companies?where=Name eq 'Pierce & Pierce' This causes errors on the server side since the ampersand is (correctly) interpreted as a query arg delimiter. What I really need it to return is the original string: http://localhost/companies?where=Name eq 'Pierce %26 Pierce' How can I work around this behavior without discarding System.Uri entirely? I can't replace all ampersands with %26 at the last moment because there will usually be multiple query args involved and I don't want to destroy their delimiters. Note: A similar problem was discussed in this question but I'm specifically referring to System.Uri.

  • stopping backspace on multiple browsers using jQuery

    - by jboyd
    I am attempting to stop a backspace keydown event from being handled by browsers, I'm using the jquery library, so I need to get the original event, but on some browsers (firefox at least) I get an error when trying to set the original events keyCode = 0, it gives and error saying that only a getter exists for that property. function blockBackspace(event) { var altKey = event.originalEvent.altKey; var srcElementType = event.originalEvent.srcElement; if( (altKey) || ((event.keyCode == 8) && (srcElementType != "text" && srcElementType != "textarea" && srcElementType != "password")) || ((event.ctrlKey) && ((event.keyCode == 78) || (event.keyCode == 82)) ) || (event.keyCode == 116) ) { event.keyCode = 0; event.returnValue = false; event.originalEvent.keyCode = 0; event.originalEvent.returnValue = false; //sets process backspaceFlag to keep multiple handlers from removing text processBackspace = true; } } so I'm not exactly sure what to do next, every solution I find yields more problems. There must be ways around this problem or else other text areas (that's kind of what I'm building) would not work

  • How to deserialize an element as an XmlNode?

    - by mackenir
    When using Xml serialization in C#, I want to deserialize a part of my input XML to an XmlNode. So, given this XML: <Thing Name="George"> <Document> <subnode1/> <subnode2/> </Document> </Thing> I want to deserialize the Document element to an XmlNode. Below is my attempt which given the XML above, sets Document to the 'subnode1' element rather than the 'Document' element. How would I get the code to set the Document property to the Document element? using System; using System.IO; using System.Xml; using System.Xml.Serialization; [Serializable] public class Thing { [XmlAttribute] public string Name {get;set;} public XmlNode Document { get; set; } } class Program { static void Main() { const string xml = @" <Thing Name=""George""> <Document> <subnode1/> <subnode2/> </Document> </Thing>"; var s = new XmlSerializer(typeof(Thing)); var thing = s.Deserialize(new StringReader(xml)) as Thing; } } However, when I use an XmlSerializer to deserialize the XML above to an instance of Thing, the Document property contains the child element 'subnode1', rather than the 'doc' element. How can I get the XmlSerializer to set Document to an XmlNode containing the 'doc' element.

Any suggestions? Thank you

  • Minimum privileges to read SQL Jobs using SQL SMO

    - by Gustavo Cavalcanti
    I wrote an application to use SQL SMO to find all SQL Servers, databases, jobs and job outcomes. This application is executed through a scheduled task using a local service account. This service account is local to the application server only and is not present in any SQL Server to be inspected. I am having problems getting information on job and job outcomes when connecting to the servers using a user with dbReader rights on system tables. If we set the user to be sysadmin on the server it all works fine. My question to you is: What are the minimum privileges a local SQL Server user needs to have in order to connect to the server and inspect jobs/job outcomes using the SQL SMO API? I connect to each SQL Server by doing the following: var conn = new ServerConnection { LoginSecure = false, ApplicationName = "SQL Inspector", ServerInstance = serverInstanceName, ConnectAsUser = false, Login = user, Password = password }; var smoServer = new Server (conn); I read the jobs by reading smoServer.JobServer.Jobs and read the JobSteps property on each of these jobs. The variable server is of type Microsoft.SqlServer.Management.Smo.Server. user/password are of the user found in each SQL Server to be inspected. If "user" is SysAdmin on the SQL Server to be inspected all works ok, as well as if we set ConnectAsUser to true and execute the scheduled task using my own credentials, which grants me SysAdmin privileges on SQL Server per my Active Directory membership. Thanks!

  • jQuery code working in Safari and Chrome but not Firefox

    - by Chris Armstrong
    I'm got a site that has a long list of tweets, and as you scroll down the right column follows you down, showing stats on the tweets. (See it in action at http://www.grapevinegame.com . Click 'memorise', then 'skip' to get to the list page. Works in Safari and Chrome). I'm using jQuery to update the top-margin of the right column, increasing it as I scroll down. It seems to be working fine in webkit-based browsers, but doesn't budge in Firefox. Heres the code, the right column element is a div with id = "distance". // Listen for scroll function $(window).scroll(function () { // Calculating the position of the scrollbar var doc = $("body"), scrollPosition = $("body").scrollTop(), pageSize = $("body").height(), windowSize = $(window).height(), fullScroll = (pageSize) - windowSize; percentageScrolled = (scrollPosition / fullScroll); var entries = $("#whispers-list > li").length; // Set position of distance counter $('div#distance').css('margin-top', ($("#whispers-list").height()+$("#latest-whisper").height()+33)*percentageScrolled); // Update distance counter $('#distance-travelled').text(Math.round(distanceTravelled*(1-percentageScrolled))); $('#whispers-list li').each(function(index) { //highlight adjacent whispers if ($('#whispers-list li:nth-child('+(index+1)+')').offset().top >= $('#distance').offset().top && $('#whispers-list li:nth-child('+(index+1)+')').offset().top <= $('#distance').offset().top + $('#distance').height()) { // alert("yup"); $('#whispers-list li:nth-child('+(index+1)+') ul').fadeTo(1, 1); } else { $('#whispers-list li:nth-child('+(index+1)+') ul').fadeTo(1, 0.5); } }); }); Appreciate any help or advice!

  • MonoRail ActiveRecord - The UPDATE statement conflicted with the FOREIGN KEY SAME TABLE

    - by Justin
    Hey all, I'm new to MonoRail and ActiveRecord and have inherited an application that I need to modify. I have a Category table (Id, Name) and I'm adding a ParentId FK which references the Id in the same table so that you can have parent/child category relationships. I tried adding this to my Category model class: [Property] public int ParentId { get; set; } I also tried doing it this way: [BelongsTo("ParentId")] public Category Parent { get; set; } When I call a method to get all parent categories (they have a null ParentId), it works fine: public static Category[] GetParentCategories() { var criteria = DetachedCriteria.For<Core.Models.Category>(); return (FindAllByProperty("ParentId", null)); } However, when I call a method to get all child categories within a specific category, it errors out: public static Category[] GetChildCategories(int parentId) { var criteria = DetachedCriteria.For<Core.Models.Category>(); return (FindAllByProperty("ParentId", parentId)); } The error is: "The UPDATE statement conflicted with the FOREIGN KEY SAME TABLE constraint \"FK_Category_ParentId\". The conflict occurred in database \"UCampus\", table \"dbo.Category\", column 'Id'.\r\nThe statement has been terminated." I'm hard-coding in the parentId parameter as 1 and I'm 100% sure it exists as an id in the Category table so I don't know why it'd give this error. Also, I'm doing a select, not an update, so what is going on here?? Thanks for any input on this, Justin

E.g. let downloadUrl(url:string) = async { let req = HttpWebRequest.Create(url) // Run operation asynchronously let! resp = req.AsyncGetResponse() let stream = resp.GetResponseStream() // Dispose 'StreamReader' when completed use reader = new StreamReader(stream) // Run asynchronously and then return the result return! reader.AsyncReadToEnd() } In F# expert book (and many other sources), they say like let! var = expr simply means "perform the asynchronous operation expr and bind the result to var when the operation completes. Then continue by executing the rest of the computation body" I also know that a new thread is created when performing async operation. My original understanding was that there are two parallel threads after the async operation, one doing I/O and one continuing to execute the async body at the same time. But in this example, I am confused at let! resp = req.AsyncGetResponse() let stream = resp.GetResponseStream() What happens if resp has not started yet and the thread in the async body wants to GetResponseStream? Is this a possible error? So maybe my original understanding was wrong. The quoted sentences in the F# expert book actually means that "creating a new thread, hang the current thread up, when the new thread finishes, wake up the body thread and continue", but in this case I don't see we could save any time. In the original understanding, the time is saved when there are several independent IO operations in one async block so that they could be done at the same time without intervention with each other. But here, if I don't get the response, I cannot create the stream; only I have stream, I can start reading the stream. Where's the time gained?

  • Redeclared javascript global variable overrides old value in IE

    - by Yousuf Haider
    (creating a separate question after comments on this: http://stackoverflow.com/questions/2634410/javascript-redeclared-global-variable-overrides-old-value) I am creating a globally scoped variable using the square bracket notation and assigning it a value inside an external js file. In another js file I declare a var with the same name as the one I just created above. Note I am not assigning a value. Since this is a redeclaration of the same variable the old value should not be overriden as described here: http://www.w3schools.com/js/js_variables.asp Create 2 javascript files with the following content : Script1 //create global variable with square bracket notation window['y'] = 'old'; Script2 //redeclaration of the same variable var y; if (!y) y = 'new'; alert(y); //shows New instead of Old in IE Include these 2 files in your html file <html> <head></head> <body> <script type="text/javascript" src="my.js"></script> <script type="text/javascript" src="my2.js"></script> </body> </html> Opening this page in Firefox and Chrome alerts 'old' which is the expected behavior. However in IE 8 the page will actually alert 'new' Any ideas on why this happens on IE ?

  • what dataprovider in flex (aside from ArrayCollection) will work for single, non-repeating XML nodes

    - by Rees
    hello, i asked this question before but haven't been able to get an answer.. i get the following error when i retrieve an XML that only has 1 node (no repeating nodes) from a PHP page and i try to store in an ArrayCollection. -When I have MORE than 1 "name" nodes...i do NOT get an error. TypeError: Error #1034: Type Coercion failed: cannot convert "XXXXXX" to mx.collections.ArrayCollection. this error occurs as the line of code: myList= e.result.list.name; I'm using this ArrayCollection as a dataprovider for a Component -is there an alternative I can use that will take BOTH single and repeating nodes as well as work as a dataprovider? Thanks in advance! code: [Bindable] private var myList:ArrayCollection= new ArrayCollection(); private function getList(e:Event):void{ var getStudyLoungesService:HTTPService = new HTTPService(); getStuffService.url = "website.com/asdf.php"; getStuffService.addEventListener(ResultEvent.RESULT, onGetList); getStuffService.send(); } private function onGetList(e:ResultEvent):void{ myList= e.result.list.name; }

  • How to get JSON code into MYSQL database?

    - by the_boy_za
    I've created this form with a jQuery autocomplete function. The selected brand from the autocomplete list needs to get sent to a PHP file using $.ajax function. My code doesn't seem to work but i can't find the error. I don't know why the data isn't getting inserted into MYSQL database. Here is my code: JQUERY: $(document).ready(function() { $("#autocomplete").autocomplete({ minLength: 2 }); $("#autocomplete").autocomplete({ source: ["Adidas", "Airforce", "Alpha Industries", "Asics", "Bikkemberg", "Birkenstock", "Bjorn Borg", "Brunotti", "Calvin Klein", "Cars Jeans", "Chanel", "Chasin", "Diesel", "Dior", "DKNY", "Dolce & Gabbana"] }); $("#add-brand").click(function() { var merk = $("#autocomplete").val(); $("#selected-brands").append(" <a class=\"deletemerk\" href=\"#\">" + merk + "</a>"); //Add your parameters here var param = JSON.stringify({ Brand: merk }); $.ajax({ type: "POST", async: true, url: "scripttohandlejson.php", contentType: "application/json", data: param, dataType: "json", success: function (good){ //handle success alert(good) }, failure: function (bad){ //handle any errors alert(bad) } }); return false; }); }); PHP FILE: scripttohandlejson.php <?PHP $getcontent = json_decode($json, true); $getcontent->{'Brand'}; $vraag ="INSERT INTO kijken (merk) VALUES ='$getcontent' "; $voerin = mysql_query($vraag) or die("couldnt put into db"); <?
