if exist else insert PHP

php,sql,pdo

It should be: if ($video_title == $q->video_title) When you use PDO::FETCH_OBJ, each column is a property of the object. You also need to be more specific in the query, otherwise you're just testing whether the video is the first one returned by the query. $video_title = "marvel.mp4"; $stmt - $dbh->prepare("SELECT...

Custom shape progress bar [closed]

javascript,css,svg,progress-bar

It is fairly simple with a mix of CSS and a little jQuery. // Add click handler to the original dots $("UL.progress LI").click(function(e) { // Deselect current selection $("UL.progress LI.selected").removeClass("selected"); var newDot = $(this); // Which dot are we selecting? var newProgressWidth = newDot.index(); // Animate the new width of...

netwire: dealing with laziness(?) in mutually dependent wires

haskell,lazy-evaluation,netwire

This behavior is due to a simple logical error in velW. velW isn't changing the velocity when it bounces, it's only changing the initial velocity for the next time the velocity is calculated; they should both change. Here's a correct version. -- did-bounce -> velocity, initial velocity in the argument...

Unable to start Liberty Profile from Command Line : failed to create task or type antlib:com.ibm.websphere.wlp.ant:server

ant,websphere-8,websphere-liberty

I've tested the following build file on ant 1.7.1 and it works fine. I'm getting your error, if I remove wlp-anttasks.jar from ant\lib folder. So double check, if the file is there and is readable - correct permissions? Maybe you are running build from different user? Or maybe you don't...

How do I revert back to original position when you hit 'cancel' upon delete confirmation (JQUERY UI draggable & droppable )?

jquery,drag-and-drop

Solution is pretty well unguessable. I found it here. $('.trash').droppable({ accept: '.draggable', drop: function (event, ui) { if (confirm('Are you sure you want to delete?')) { ui.draggable.remove(); } else { ui.draggable.draggable('option','revert',true); } } }); An no, you haven't gone cross-eyed, .draggable really does appear twice. updated fiddle...

Using Contains() to check multiple object values exist in list before adding new list?

You can use GroupBy operator, because in fact your operation is grouping: returnVehicles = modelVehicles.GroupBy(x => new { x.Year, x.Make, x.Model }, x => new Foo() { Year = x.Year, Make = x.Make, Model = x.Model }, (key, values) => values.First()) .ToList(); And if you implement Equals and GetHashCode for...

WinRT CoreDispatcher RunAsync and closures

c#,windows-runtime,dispatcher,synchronizationcontext

I don't think you need to worry about it. Using a closure is likely to be just fine; I doubt you'll observe any significant performance decrease. Note that in other cases where you can pass parameters to the invoked method, you still wind up with an allocation. At a minimum,...

How can i insert return value to mysql database in python?

python,mysql

Assuming the 'warnings' are the only errors -- then it's just a matter of converting from the python types to the SQL database's column types. Chances are, your python types are set with a higher level of precision than the columns in the table. This is what it means by...

Make colors in plot and imagesc the same

matlab

It's hard to tell how you want the colours to be ordered, but this will change the colormap from the default to copper. %// sample data field=randi(7,10); distribution=rand(100,7); h=figure(1); set(gcf,'PaperPositionMode','auto') set(h, 'Position', [500 500 1000 500]) subplot(1,2,1); imagesc(field); colormap('copper'); colorbar h=subplot(1,2,2); set(get(h,'Parent'),'DefaultAxesColorOrder',copper(7)) %// set the ColorOrder for this plot plot(distribution);...

Does Rebus support using MSMQ over HTTP/HTTPS?

msmq,rebus

With the existing MSMQ transport, Rebus does not support MSMQ over HTTP/HTTPS. Rebus will always use ordinary private MSMQ queues, and you specify queue names like this: <add messages="MyNameSpace.MyMessage, MyAssembly" endpoint="myqueue.input" /> to map the messages to a local myqueue.input queue, or <add messages="MyNameSpace.MyMessage, MyAssembly" endpoint="[email protected]" /> to map the...

Ruby = use regex to replace a line in string with blank space

“Missing argument parameter 'queue' in call”

ios,swift,ios8,sprite-kit

Swift sometimes emits errors that don't have anything to do with the real problem. In this case your problem is that SKAction.waitForDuration expects an NSTimeInterval but you are passing in a CGFloat. You need to construct an NSTimeInterval from the CGFloat. let sequence = [ SKAction.runBlock(spawnObstacle), SKAction.waitForDuration(NSTimeInterval(random(min: player.speed, max: player.speed...

jquery loop through select tags on option change

javascript,jquery,html,selectedtext

It looks like you started thinking that you'd need to loop through every select...but since you said that you need to "figure out which select element they chose" you can rely on the this keyword inside of a change callback. Fiddle: http://jsfiddle.net/vpqh3kjz/ Code: // Every time someone updates either selected...

Bower is installed and in path, but not recognized
