  • [JS] How to manipulate a PHP Array in javascript?

    - by rasouza
    I have an Array in PHP which contains data from database. And it prints out also as a table in the same page which has an AJAX delete function. Trying to explain better The array contains debt sums related to many people, it is the application's main function. In the same page, there is a table containing every debt record related to the array, which can be deleted or edited using AJAX. I have coded the part of deleting the record and removing the TR entry, but it's not enough: I'd like to change also the debt sum using AJAX which is an PHP Array. What I have I have the JS function which removes the TR when the delete button is clicked // TR Fading when deleted $('.delete') .click(function() { $.ajax({ type: 'GET', url: 'history/delete/id/'+$(this).attr('id') }); $(this).parent().parent().fadeOut(); return false; }); and I have the PHP array (image)

  • jQuery fadeTo not working in IE8

    - by Lynda
    I have a div fading in using fadeTo. It works great in Firefox and IE9. It does not work in IE8. Here is my code: JS: var $j = jQuery.noConflict(); window.onload = function(){ $j('#fadein').fadeTo(6000, 1, function() { }); }; HTML <div class="img-center" id="fadein" style="opacity:0;"> <img src="src.jpg" alt="Text" class="feature-image" /> </div> How do I get this to work in IE8? I do not mind changing from fadeTo to fadeIn or some other method of fading in a div as long as it works in IE8.

  • PHP - MySQL - Select runs indefinitely

    - by John
    I have three tables listings: id, pid, beds, baths, etc, etc, etc, db locations: id, pid, zip, lat, lon, etc, etc, etc, db images id, pid, height, width, raw, etc, etc, db id, pid & db are indexed. db just references the mls provider a particular item came from. in images the raw column holds raw image data there are about 15k rows in listings/locations, and about 120k rows in images so there are multiple rows that have the same pid. when i do "select pid from listings" or "select pid from locations" the query completes successfully in about 100ms. when i do "select pid from images" it just hangs in sqlyog and never completes... i was thinking since the raw column contains alot of information that it might be trying to select that too, but my query doesn't try to select that so I can't imagine why it's taking so long... any idea why this is happening??

    I'm trying to get an SVG image to show up on my iPhone (or iPad) default browser, but I can't seem to get even just a rect to show up.

  • Managing multiple blogs (wordpress) from one control panel

    - by thisMayhem
    This is the deal: I have more than one blog (not running yet) that I want to install in subfolders for one of my domains. Each blog will obviously have its own look and feel and content. I could just have a set of control panels and administer them individually or I could somehow manage them form a single control panel. Issues I've come across are: Some plugins offer this functionality while suppressing other features like auto draf saving, in-post category and tag creation, image upload etc. I'm not necessarily looking for a ready solution, more like some guidance on how to approach this particular problem in the best possible manner. I'm looking for a fully working scenario, not some plugin that allows me to more or less simulate the one-blog-administration experience.

  • How to prevent a specific directory from running Php, Html, and Javascript languages?

    - by Emily
    Hi, Let's say i have an image uploader script, i want to prevent the upload directory from executing Php or even html by only showing it as plain text, i've seen this trick in many websites but i don't know how they do it. Briefly, if i upload evil.php to that directory, and i try to access it i will only see a plain text source , No html or php is executed. ( but i still want the images to appear normally ofcourse) I know i can do like that by header("content-type:text/plain"); but that's will not be helpful, because what i want, is to set the content-type:text/plain automatically by the server for every thing outputed from the upload directory except images. Note: i'm running php 5.3.2/Cent OS and the latest cPanel. Thanks

  • Toggle DIV and SPAN text onclick

    - by philipryoung
    I have been trying to mimic this website http://www.designrattan.co.uk/daybed/apple for a while now. I need to make a page where the customer can click "View 360" and then it changes the DIV to show the product 360 (for which I already have the code for). I also need to make it so that when it is clicked the span text then changes to "Back to Image" I have tried many times and have failed to get the Javascript code and HTML to work well together. My efforts can be seen here: http://designliving.tk/winchester-rattan-garden-round-table-set As you can see it is a complete fail as it doesn't change the DIV it just displays a new one. Also when you click the button it then changes to text instead of a new button. If anyone can help me here I would be massively appreciative and if I need to pay you for your efforts then please contact me on [email protected]

  • How to speed this kind of for-loop?

    - by wok
    I would like to compute the maximum of translated images along the direction of a given axis. I know about ordfilt2, however I would like to avoid using the Image Processing Toolbox. So here is the code I have so far: imInput = imread('tire.tif'); n = 10; imMax = imInput(:, n:end); for i = 1:(n-1) imMax = max(imMax, imInput(:, i:end-(n-i))); end Is it possible to avoid using a for-loop in order to speed the computation up, and, if so, how?

  • Objective-C: how to allocate array of GLuint

    - by sashaeve
    I have an array of GLuint with fixed size: GLuint textures[10]; Now I need to set a size of array dynamically. I wrote something like this: *.h: GLuint *textures; *.m: textures = malloc(N * sizeof(GLuint)); where N - needed size. Then it used like this: glGenTextures(N, &textures[0]); // load texture from image -(GLuint)getTexture:(int)index{ return textures[index]; } I used the answer from here, but program fell in runtime. How to fix this? Program is written on Objective-C and uses OpenGL ES.

  • Is it possible to hide the cursor in a webpage using CSS or Javascript?

    - by yeyeyerman
    I want to hide the cursor when showing a webpage that is meant to display information in a building hall. It doesn't have to be interactive at all. I tried with the cursor property and a transparent cursor image but I didn't make it work. Does anybody know if this can be done? I suppose this can be thought as a security threat for a user that can't know where he is clicking on, so I'm not very optimistic... Thank you!

  • Strange behaviour of Android debugger in Eclipse when using Camera for preview.

    - by Buzzy
    Hi, I have an Android application that uses a SurfaceView subclass and Camera object to preview images before capture. Once I capture an image, I stop the preview and release the camera. Execution stops at any breakpoint after this. However, apart from the "Suspend" and "Terminate" icons, the rest are disabled. This is strange because the "Debug Current Instruction Pointer" is clearly at the said breakpoint and execution is already suspended. I can't perform any debugging operations and have no option but to terminate the session. Sometimes (very rarely), the session terminates by itself. I can confirm that this odd behavior takes place only after I preview the camera capture. I am fairly new to Android development. Is there some obvious mistake I am making? Any help would be highly appreciated.

  • can you use jquery lazyload on all images (not just ones out of view)

    - by ooo
    i have a webpage with a lot of images (photo album). I am using lazyloading jquery plugin which is great to only load the images out of browser view when i scroll down. The one issue i have is that i want the loading icon to show up first on images loading IN the current view as well as some of them are big images and they show up with that bad browser "image not loaded yet" icon until they download. I don't see any property on this plugin to support this for both in view and for scrolling. does anyone know if this is possible?

  • Making a video with opencv and ffmpeg. How to find the right color format?

    - by luc
    I have a webcam video recorder program built with python, opencv and ffmpeg It works ok except that the color of the video is more blue than the reality. The problem seems to come from color format of images. It seems that OpenCv is giving BGR images and ffmpeg+libx264 is expecting YUV420p. I've read that YUV420p correspond to YCbCr. opencv has no conversion from BGR to YCbCr. It only has a conversion to YCrCb. I have made some searchs and tried different alternatives to try converting opencv image to something that could be ok for ffmpeg+libx264. None is working. At this point, I am a bit lost and I would appreciate any pointer that could help me to fix this color issue.

P.S btw is it the correct way of grabbing the first instance of image tag from my HTML string?

  • conceptually different entities with a few similar properties should be stored in one table or more?

    - by Haghpanah
    Assume A and B are conceptually different entities that have a few similar properties and of course their own specific properties. In database design, should I put those two entities in one big aggregated table or two respectively designed tables. For instance, I have two types of payment; Online-payment and Manual-payment with following definition, TABLE [OnlinePayments] ( [ID] [uniqueidentifier], [UserID] [uniqueidentifier], [TrackingCode] [nvarchar](32), [ReferingCode] [nvarchar](32), [BankingAccID] [uniqueidentifier], [Status] [int], [Amount] [money], [Comments] [nvarchar](768), [CreatedAt] [datetime], [ShopingCartID] [uniqueidentifier], ) And TABLE [ManualPayments] ( [ID] [uniqueidentifier], [UserID] [uniqueidentifier], [BankingAccID] [uniqueidentifier], [BankingOrgID] [uniqueidentifier], [BranchName] [nvarchar](64), [BranchCode] [nvarchar](16), [Amount] [money], [SlipNumber] [nvarchar](64), [SlipImage] [image], [PaidAt] [datetime], [Comments] [nvarchar](768), [CreatedAt] [datetime], [IsApproved] [bit], [ApprovedByID] [uniqueidentifier], ) One of my friends told me that creating two distinct tables for such similar entities is not a well design method and they should be put in one single table for the sake of performance and ease of data manipulations. I’m now wondering what to do? What is the best practice in such a case?

  • Making dynamic images have static filenames

    - by michaeltk
    My website currently has various links to a php script that generates the images dynamically. For example, the link may say "img source="/dynamic_images.php?type=pie-chart&color=red" Obviously, this is not great for SEO. I'd like to somehow make the filenames of these links appear to be static, and use a solution (like Mod-Rewrite) to ensure that the images can still be dynamically created. I suppose I could have something like "img src="average-profits-in-scuba-diving-industry.png?type=pie-chart&color=red" (and use Mod-Rewrite to take care of changing the filename prefix to dynamic_images.php), but I'm afraid that the search engines would shy away from the querystring on the end of the image filename. Any solutions? Thanks in advance.
