  • jQuery AJAX POST gives undefined index

    - by Sebastian
    My eventinfo.php is giving the following output: <br /> <b>Notice</b>: Undefined index: club in <b>/homepages/19/d361310357/htdocs/guestvibe/wp-content/themes/yasmin/guestvibe/eventinfo.php</b> on line <b>11</b><br /> [] HTML (index.php): <select name="club" class="dropdown" id="club"> <?php getClubs(); ?> </select> jQuery (index.php): <script type="text/javascript"> $(document).ready(function() { $.ajax({ type: "POST", url: "http://www.guestvibe.com/wp-content/themes/yasmin/guestvibe/eventinfo.php", data: $('#club').serialize(), success: function(data) { $('#rightbox_inside').html('<h2>' + $('#club').val() + '<span style="font-size: 14px"> (' + data[0].day + ')</h2><hr><p><b>Entry:</b> ' + data[0].entry + '</p><p><b>Queue jump:</b> ' + data[0].queuejump + '</p><br><p><i>Guestlist closes at ' + data[0].closing + '</i></p>'); }, dataType: "json" }); }); $('#club').change(function(event) { $.ajax({ type: "POST", url: "http://www.guestvibe.com/wp-content/themes/yasmin/guestvibe/eventinfo.php", data: $(this).serialize(), success: function(data) { $('#rightbox_inside').hide().html('<h2>' + $('#club').val() + '<span style="font-size: 14px"> (' + data[0].day + ')</h2><hr><p><b>Entry:</b> ' + data[0].entry + '</p><p><b>Queue jump:</b> ' + data[0].queuejump + '</p><br><p><i>Guestlist closes at ' + data[0].closing + '</i></p>').fadeIn('500'); }, dataType: "json" }); }); </script> I can run alerts from the jQuery, so it is active. I've copied this as is from an old version of the website, but I've changed the file structure (through to move to WordPress) so I suspect the variables might not even be reaching eventinfo.php in the first place... index.php is in wp-content/themes/cambridge and eventinfo.php is in wp-content/themes/yasmin/guestvibe but I've tried to avoid structuring issues by referencing the URL in full. Any ideas?

  • Encountering NullPointerException when trying to add polynoms

    - by Ayler Cruz
    I need to add two polynomials, which is composed of two ints. For example, the coefficient and the exponent 3x^2 would be constructed using 3 and 2 as parameters. I am getting a NullPointerException but I can't figure out why. Any help would be appreciated! public class Polynomial { private Node poly; public Polynomial() { } private Polynomial(Node p) { poly = p; } private class Term { int coefficient; int exponent; private Term(int coefficient, int exponent) { this.coefficient = coefficient; this.exponent = exponent; } } private class Node { private Term data; private Node next; private Node(Term data, Node next) { this.data = data; this.next = next; } } public void addTerm(int coeff, int exp) { Node pointer = poly; if (pointer.next == null) { poly.next = new Node(new Term(coeff, exp), null); } else { while (pointer.next != null) { if (pointer.next.data.exponent < exp) { Node temp = new Node(new Term(coeff, exp), pointer.next.next); pointer.next = temp; return; } pointer = pointer.next; } pointer.next = new Node(new Term(coeff, exp), null); } } public Polynomial polyAdd(Polynomial p) { return new Polynomial(polyAdd(this.poly, p.poly)); } private Node polyAdd(Node p1, Node p2) { if (p1 == p2) { Term adding = new Term(p1.data.coefficient + p2.data.coefficient, p1.data.exponent); p1 = p1.next; p2 = p2.next; return new Node(adding, null); } if (p1.data.exponent > p2.data.exponent) { p2 = p2.next; } if (p1.data.exponent < p2.data.exponent) { p1 = p1.next; } if (p1.next != null && p2.next != null) { return polyAdd(p1, p2); } return new Node(null, null); } }

  • How to Filter ADO.NET data using a Full Text Seach (FTS) field?

    - by ActionFactory
    Hi All, We are using ADO.NET dataservices & are building URL based filters. Example: /Customers?filter=City eq 'London' We now need to filter on a Full Text 'tags' Field. WAS HOPING FOR: /Customers?filter=Tag like 'Friendly' PROBLEM: ADO.NET does not have a LIKE operator. ADO.NET does not seem to like FTS (It is not finding a match - because it is not parsing through the CSV's) Any ideas how to make this work? THX

  • @OneToOne and @JoinColumn, auto delete null entity , doable?

    - by smallufo
    I have two Entities , with the following JPA annotations : @Entity @Table(name = "Owner") public class Owner implements Serializable { @Id @GeneratedValue(strategy = GenerationType.AUTO) @Column(name = "id") private long id; @OneToOne(fetch=FetchType.EAGER , cascade=CascadeType.ALL) @JoinColumn(name="Data_id") private Data Data; } @Entity @Table(name = "Data") public class Data implements Serializable { @Id private long id; } Owner and Data has one-to-one mapping , the owning side is Owner. The problem occurs when I execute : owner.setData(null) ; ownerDao.update(owner) ; The "Owner" table's Data_id becomes null , that's correct. But the "Data" row is not deleted automatically. I have to write another DataDao , and another service layer to wrap the two actions ( ownerDao.update(owner) ; dataDao.delete(data); ) Is it possible to make a data row automatically deleted when the owning Owner set it to null ?

  • How Serializable works with insert in SQL Server 2005

    - by Spence
    G'day I think I have a misunderstanding of serializable. I have two tables (data, transaction) which I insert information into in a serializable transaction (either they are both in, or both out, but not in limbo). SET TRANSACTION ISOLATION LEVEL SERIALIZABLE BEGIN TRANSACTION INSERT INTO dbo.data (ID, data) VALUES (@Id, data) INSERT INTO dbo.transactions(ID, info) VALUES (@ID, @info) COMMIT TRANSACTION I have a reconcile query which checks the data table for entries where there is no transaction at read committed isolation level. INSERT INTO reconciles (ReconcileID, DataID) SELECT Reconcile = @ReconcileID, ID FROM Data WHERE NOT EXISTS (SELECT 1 FROM TRANSACTIONS WHERE data.id = transactions.id) Note that the ID is actually a composite (2 column) key, so I can't use a NOT IN operator My understanding was that the second query would exclude any values written into data without their transaction as this insert was happening at serializable and the read was occurring at read committed. I have evidence that reconcile is picking up entries

  • How to remove EXIF data without recompressing the JPEG?

    - by Denilson Sá
    I want to remove the EXIF information (including thumbnail, metadata, camera info... everything!) from JPEG files, but I don't want to recompress it, as recompressing the JPEG will degrade the quality, as well as usually increasing the file size. I'm looking for a Unix/Linux solution, even better if using the command-line. If possible, using ImageMagick (convert tool). If that's not possible, a small Python, Perl, PHP (or other common language on Linux) script would be ok. There is a similar question, but related to .net.

  • How can I keep data that a user has entered in my jQuery/Ajax pop-up form?

    - by Lucas McCoy
    I have a form on a website I'm working (you can see it here) on that allows my users to give feedback. It's an jQuery/Ajax popup form: $('.contact_us').click(function(){ var boxy_content; boxy_content += "<div style=\"width:300px; height:300px \"><form id=\"feedbacked\">"; boxy_content += "<p>Subject<br /><input type=\"text\" name=\"subject\" id=\"subject\" size=\"33\" /></p><p>Your E-Mail Address:<br /><input type=\"text\" name=\"your_email\" size=\"33\" /></p><p>Comment:<br /><textarea name=\"comment\" id=\"comment\" cols=\"33\" rows=\"5\"></textarea></p><br /><input type=\"submit\" name=\"submit\" value=\"Send >>\" />"; boxy_content += "</form></div>"; // Other code here... Is there anyway I can save what the user has entered (in case they see our error message when they try to submit)?

  • camera picturecallback intent not work

    - by Simon
    After I take the photo, the program automatically goes back like onBackPressed(). When I remove the putExtra, the intent runs. When I put startActivity() after takePicture(), it transfers null data.... I just want to put the image data to another activity to have other use. How can it be achieved? private PictureCallback picture = new PictureCallback(){ @Override public void onPictureTaken(byte[] data, Camera camera) { // TODO Auto-generated method stub Intent intent = new Intent(CameraFilming.this, PhotoPreview.class); intent.putExtra("imageByte", data); //Picture data transfer to next activity startActivity(intent); } }; //take photo by pressing button private class captureBtnListener implements View.OnClickListener{ @Override public void onClick(View v){ capture.setOnClickListener(null); CountDownTimer timer = new CountDownTimer(10000, 1000){ @Override public void onTick(long millisUntilFinished) { // TODO Auto-generated method stub countdown.setText(millisUntilFinished/1000+""); } @Override public void onFinish() { // TODO Auto-generated method stub countdown.setText("0"); camera.takePicture(null, null, picture); } }; timer.start(); } } public class PhotoPreview extends Activity{ private RelativeLayout layout; private ImageView overlay, texture, face1, face2; @Override public void onCreate (Bundle savedInstanceState){ super.onCreate(savedInstanceState); setContentView(R.layout.photo_preview); layout = (RelativeLayout)findViewById(R.id.preview_layout); byte[] data = getIntent().getByteArrayExtra("imageByte"); if (data == null){ Log.d("PhotoPreview", "no image data"); finish(); } Bitmap rawPhotoBitmap = BitmapFactory.decodeByteArray(data, 0, data.length); ImageProcess imgProcess = new ImageProcess(this); Bitmap resizedFace = imgProcess.scaleAccordingWidth(imgProcess.cropImage(rawPhotoBitmap, 840, 125, 440, 560), 77); face1 = new ImageView(this); face1.setImageBitmap(resizedFace); Log.d("testing", "testing"); } }

  • How can I handle multiple views of a data object? Which design pattern is acceptable?

    - by tranquil.byte
    I have a person object. class Person { private $name; ... } I need to be able to change how they are displayed on the front-end ( visitors have control ). They can choose list view, grid view, photo view for example. class PersonDisplay { public function displayList() { // Query database // Output html to display in list mode } public function displayPhoto() { // Query database // Output html to display in photo mode } } Is this an acceptable way to handle the presentation of the items on the front-end or is there a specific design pattern I should be researching to help me with this task? Does anyone have any suggestions or ideas where this could go wrong or if this could potentially make maintenance a nightmare? The Person object was just an example very similiar to what I am using.

  • javascript: how to delay submitting data when several checkboxes clicked in short time interval?

    - by ~knb
    I have an array of checkboxes in a complex dynamic-html form. Whenever a user clicks one checkbox, a fairly expensive query is generated and submitted to a remote server. I want to delay this submit action depending on the users next action. If the user clicks several checkboxes quickly, all of the first clicks should be discarded, only the last one is processed and eventually submitted after 1 second or so. maybe this is a common problem but I have never worked with timeouts before.

  • Need a good way to store data in a DB from a table on a webpage that can have N columns.

    - by Abe Miessler
    Users need to be able to add a specific type of column to an otherwise static table on my web page and then save the information they enter in there to the database. I've been told that in reality they will almost never go over 5 columns but I would rather support N. The columns will all be of the same datatype. My first thought was to have an XML column with the values from all added columns in there but I was curious if anyone else had come up with a better solution. Suggestions?
