PHP : How to get specific data from array

Hello! I try to use amazon API using PHP. If I use print_r($parsed_xml->Items->Item->ItemAttributes) it show me some result like SimpleXMLElement Object ( [Binding] = Electronics [Brand] = Canon [DisplaySize] = 2.5 [EAN] = 0013803113662 [Feature] = Array ( [0] = High-powered 20x wide-angle optical zoom with Optical Image Stabilizer [1] = Capture 720p HD movies with stereo sound; HDMI output connector for easy playback on your HDTV [2] = 2.5-inch Vari-Angle System LCD; improved Smart AUTO intelligently selects from 22 predefined shooting situations [3] = DIGIC 4 Image Processor; 12.1-megapixel resolution for poster-size, photo-quality prints [4] = Powered by AA batteries (included); capture images to SD/SDHC memory cards (not included) ) [FloppyDiskDriveDescription] = None [FormFactor] = Rotating [HasRedEyeReduction] = 1 [IsAutographed] = 0 [IsMemorabilia] = 0 [ItemDimensions] = SimpleXMLElement Object ( [Height] = 340 [Length] = 490 [Weight] = 124 [Width] = 350 ) [Label] = Canon [LensType] = Zoom lens [ListPrice] = SimpleXMLElement Object ( [Amount] = 60103 [CurrencyCode] = USD [FormattedPrice] = $601.03 ) [Manufacturer] = Canon [MaximumFocalLength] = 100 [MaximumResolution] = 12.1 [MinimumFocalLength] = 5 [Model] = SX20IS [MPN] = SX20IS [OpticalSensorResolution] = 12.1 [OpticalZoom] = 20 [PackageDimensions] = SimpleXMLElement Object ( [Height] = 460 [Length] = 900 [Weight] = 242 [Width] = 630 ) [PackageQuantity] = 1 [ProductGroup] = Photography [ProductTypeName] = CAMERA_DIGITAL [ProductTypeSubcategory] = point-and-shoot [Publisher] = Canon [Studio] = Canon [Title] = Canon PowerShot SX20IS 12.1MP Digital Camera with 20x Wide Angle Optical Image Stabilized Zoom and 2.5-inch Articulating LCD [UPC] = 013803113662 ) my goal is to get only Feature infomation and I try to use $feature = $parsed_xml->Items->Item->ItemAttributes->Feature it does'not work for me because it just show me the first feature only.

jQuery slideDown + CSS Floats

- by danilo

I'm using a HTML Table with several rows. Every second row - containing details about the preceding row - is hidden using CSS. When clicking the first row, the second row gets showed using jQuery show(). This is quite nice, but I would prefer the slideDown-Effect. The problem is, inside the details row, there are two floating DIVs, one floating on the left, and one on the right. Now if i slideDown the previously hidden row, the contained DIVs behave strange and "jump around". See this animated gif to understand what I mean: http://ich-wars-nicht.ch/tmp/lunapic_127365879362365_.gif The markup: <tr class="row-vm"> <td>...</td> ... </tr> <tr class="row-details"> <td colspan="8"> <div class="vmdetail-left"> ... </div> <div class="vmdetail-right"> ... </div> </td> </tr> The CSS: .table-vmlist tr.row-details { display: none; } div.vmdetail-left { float: left; width: 50%; } div.vmdetail-right { float: right; width: 50%; } And the jQuery code: if ($(this).next().css('display') == 'none') { // Show details //$(this).next().show(); $(this).next().slideDown(); } else { // Hide details //$(this).next().hide(); $(this).next().slideUp(); } Is there a way to fix this behavior, and to implement a nice slideDown-effect?

Wrong values reported by pyPDF for various box regions

- by romor

Using pyPdf, for most files I get matched results concerning various box's dimensions compared to what Acrobat reports. However for some files I get different values reported by pyPdf and Acrobat, like: pyPdf: artBox: 595.3 x 841.9 bleedBox: 595.3 x 841.9 cropBox: 595.3 x 841.9 trimBox: 517.3 x 754 Acrobat: artBox: 439.35 x 666.13 pt bleedBox: 439.35 x 666.13 pt cropBox: 439.35 x 666.13 pt trimBox: 439.35 x 666.13 pt I thought it's units issue, but then ratio between widths and heights doesn't match also, not mentioning trimBox mismatch Correct results are those reported by Acrobat of course. Does someone know why is this and is there a way I get correct dimensions by using pyPdf? Thanks couple of minutes later... After reading this question: Are PDF box coordinates relative or absolute? I figured I didn't considered uper left corner to be different then 0 (zero). It turned out that box starts at 77.95 x 87.87, so if we reduce reported values of trimBox by this values correct result is obtained. artBox: 0 x 0 bleedBox: 0 x 0 cropBox: 0 x 0 trimBox: 77.95 x 87.87 Other boxes seem with misleading values or I misinterpret them. Snippet: from pyPdf import PdfFileReader pdfread = PdfFileReader(file('my.pdf', 'rb')) page = 1 width = pdfread.getPage(page).trimBox[2]-pdfread.getPage(page).trimBox[0] height = pdfread.getPage(page).trimBox[3] - pdfread.getPage(page).trimBox[1] print width, height

Why does my floating div push around other divs?

- by Meke

I have a div which has a table which has a google map. I want to place a info box within the google map external to the map, just floating on top But I can't seem to get it right, the info div just pushes around the google map despite being on top of the map... CSS .google_map { height: 270px; width: 100%; } #flightMapInfo { position: relative; float: left; z-index: 100; color: #FFFFFF; top: 30px; left: 50px; background:#5a85a5; padding: 5px; -moz-border-radius: 10px; -webkit-border-radius: 10px; } div.tabContent { border: 1px solid #c9c3ba; padding: 0.5em; background-color: #f1f0ee; min-height: 300px; } .tableLeft { width: 75%; float: left; border-right: dotted 2px black; } HTML <div class="mapBlock tabContent"> <div id="flightMapInfo">WHARGL</div> <table class="tableLeft"> <tr><td><div id="flightMap" class="google_map"></div> </table></td></tr></div>

Gradient fills only half the cell

- by Gopal

Hi, How do I get the IE gradient function here in this code sample to completely fill the table cell? With the code given below, I could only get it to cover the upper half of the cell. <HTML> <HEAD> <style>  </style></HEAD> <BODY> <table x:str cellspacing=0 style='table-layout:fixed; border-left:1.0pt solid; border-top:1.0pt solid; border-right:1.0pt solid; border-bottom:1.0pt solid; border-left-color:#c0c0c0; border-top-color:#c0c0c0; border-right-color:#c0c0c0; border-bottom-color:#c0c0c0; '> <col style='width:67pt;'> <tr style='height:28.00pt'> <td class=cl1 style='width:67pt;'>Cell Text</td> </tr> </BODY> </HTML>

How To Read A Remote Text File

- by XcodeDev

Hi, I would like to read a remote text file called posts.txt on my website. An example of the insides of the posts.txt file would be this: <div style="width : 300px; position : relative"><font face="helvetica, geneva, sans serif" size="6"><b>2</b></font><font face="helvetica, geneva, sans serif" size="4"><i> scored by iSDK</i></font><br><img src="Bar.png" /></div><div style="width : 300px; position : relative"><font face="helvetica, geneva, sans serif" size="6"><b>2</b></font><font face="helvetica, geneva, sans serif" size="4"><i> scored by martin</i></font><br><img src="Bar.png" /></div> What I wanted to know is how can I get the score, and scored by text from the .txt file? The score is (in this case) the: <b>2</b>, and the scored by text in this case would be: "scored by iSDK". Any code telling me how to do this is twice as helpful! Thanks in advanced XcodeDev

CSS positioning div above another div when not in that order in the HTML

- by devmode

Given a template where the HTML cannot be modified because of other requirements, how is it possible to display a div above another div when they are not in that order in the HTML and both divs contain data that could produce a varying height and width. HTML: <div id="wrapper" <div id="firstDiv" Content to be below in this situation </div <div id="secondDiv" Content to be above in this situation </div </div Other elements Hopefully it is obvious that the desired result is: Content to be above in this situation Content to be below in this situation Other elements When the dimensions are fixed it easy to position them where needed, but I need some ideas for when the content is variable. For the sake of this scenario, please just consider the width to be 100% on both. Edit: A CSS solution is the most ideal solution. Thank you for the Javascript options mentioned. Without getting too wordy about what or why (or who) ... I am specifically looking for a CSS only solution (and it will probably have to be met with other solutions if that doesn't pan out). One more ... there are other elements following this. A good suggestion was mentioned given the limited scenario I demonstrated -- given that it might be the best answer, but I am looking to also make sure elements following this aren't impacted.

Binding Listbox item source to a collection of collections in windows phone 7

- by Tee

Hi there, I am trying to bind a Listbox ItemSource to a collection of multiple Lists. i.e. List PersonCollection List Person List Collection Now I need to show items from both of these list. In wpf you could use HierarchicalDataTemplate i believe, but not sure how I can do it in windows phone 7. Tried with Blend and it generates the following data template. <DataTemplate x:Key="PersonDataTemplate"> <Grid> <StackPanel Margin="0,0,1,0" Orientation="Vertical" VerticalAlignment="Top"> <TextBlock Margin="0,0,1,0" TextWrapping="Wrap" Text="{Binding Person[0].Name}" d:LayoutOverrides="Width"/> <TextBlock Margin="0,0,1,0" TextWrapping="Wrap" Text="{Binding Collection[0].Total}" d:LayoutOverrides="Width"/> </StackPanel> </Grid> </DataTemplate> Is there another way I can do this? I have tried to set the DataContext of Textbox in DataTemplate to individual arrays but did not seem to work. Cant find anything similar on the net apart from the confirmation that HierarchicalDataTemplate is not supported in Windows Phone 7. I have other ways to do but none elegant.. Thanks in advance. Regards

Updating Embedded Video in Firefox

- by Slevin

I am working on a Videos page where my intention is to load a video with the page but by clicking a link, the original video will be updated and replaced with the corresponding video. For instance, if video1 loads with the page and the user clicks to view video2, the original div's innerHTML holding video1 is updated to play video2. Now, I have works great in IE and Chrome but nothing loads at all in Firefox. Below are some snippets of my code. Any idea how to load these videos in a manner that Firefox supports? Javascript Function function updateVideo(arraynum) { var arraynum; var vidId = document.anchors(arraynum).name; document.getElementById("movieDiv").innerHTML = "<object width='340' height='300'><param name='movie' value='http://www.youtube.com/v/" + vidId + "&h1=en&fs=1&color1=0x5d1719&color2=0xcd311b'></param><param name='wmode' value='opaque'></param><embed src='http://www.youtube.com/v/" + vidId + "&h1=en&fs=1&color1=0x5d1719&color2=0xcd311b' type='application/x-shockwave-flash' wmode='opaque' width='340' height='300'></embed></object>"; Html <div id = "movieDiv"> </div> Links <a name="-MQf_Ol00nk" href = "#" onclick="updateVideo(4)"><img src="../images/content/videos/kaleidoscope/2010/May/Arts-and-Events.jpg" border = "0"></a> Any help with this issue would be greatly appreciated. And on a smaller note, every time a link in clicked in IE, a '#' is added into the title bar. So clicking three or four videos would result in the page title being followed up with three or four # signs.

How do I capture keystrokes on the web?

How to use ID selector after jQuery html()

- by user555617

It's amazing to try to understand why the function alert("hello") is not generated after clicking more than once... There is some method to do this function is executed? Note that doesn't work after update using html() involving id "press" in button. Any idea? See: http://jsbin.com/atuqu3 JavaScript: $(document).ready(function (){ $("#press").click(function() { $("#relation-states").html('<select id="state" name="state"> <option value="Texas">Texas</option> </select><button id="press" type="button" title="" aria-haspopup="true" style="width: 175px;"><span>Select an item</span></button>');; alert("hello"); }); }); HTML: <div id="relation-states"> <select id="state" name="state"> <option value="New York">New York</option> </select> <button id="press" type="button" title="" aria-haspopup="true" style="width: 175px;"><span>Select an item</span></button> </div>

HTML Double Click Selection Oddity

- by Aren B

I didn't post this on DocType because it's not really a design thing, the visual representation isn't my problem, the behaviour is. I'm sorry if this is misplaced but I don't feel it's a designer issue. The following DOM: <ul style="overflow: hidden;"> <li style="float: left;"><strong>SKU:</strong>123123</li> <li style="float: left;"><strong>ILC:</strong>asdasdasdasd</li> </ul> Or <div style="overflow: hidden;"> <div style="float: left; width: 49%"><strong>SKU:</strong>123123</div> <div style="margin-left: 50%; width: auto;"><strong>ILC:</strong>asdasdasdasd</div> </div> Or <p> <span><strong>SKU:</strong>123123</span> <span><strong>ILC:</strong>asdasdasdasd</span> </p> All present me an odd problem in IE 6 IE 7 Firefox 3.x Chrome But not in IE 8 When you double click '123123' after 'SKU:', it selects '123123' AND 'ILC:' from the next dom element. Take any text on this page (here in SO), double click a word, it only selects THAT WORD, even in the middle of a paragraph. These examples have dom elements closing them, anyone know why this is happening. My fellow employees use the 'double click' mechanism to select the relevant product ID's to do their job, and this dosen't make sense to me what soever.

Get Highest Res Favicon

- by Jeremy

I'm making a website that needs to dynamically obtain the favicon of sites upon request. I've found a few api's that can accomplish this fairly well, and so far I'm liking http://www.fvicon.com/. The final image for my website will be 64x64px, and some websites such as Google and Wordpress have nice images of this size that are easily retrieved via this api. Though, of course, most websites only have a 16x16 favicon image and scaling that image to 64x64 has very bad quality loss. Examples: (high res) http://a.fvicon.com/wordpress.com?format=png&width=64&height=64 (low res) http://a.fvicon.com/yahoo.com?format=png&width=64&height=64 Keeping this in mind, I'm planning on somehow determining whether a high-res image is available and, if so, the website will use this image. If not, I want to use a pre-made 64x64 icon with the smaller icon layered over it. What I'm having trouble with is determining if there is a high res favicon available or not. Also, I'm curious if there's a better approach to this situation. I'd rather not use smaller images (64x64 works out really well for this project). The lowest res I'm willing to drop to is 48x48 but even then there will be a significant quality loss for scaling up 16x16 favicons. Any ideas? If you need any more information I will gladly provide it. Thank you!

How can I programmatically position a view using relative points?

- by Steve Madsen

What is the best way to position a view relative to the size of its superview, when the bounds of the superview are not yet known? I am trying to avoid hard-coding coordinates if it is at all possible. Perhaps this is silly, and if so, that's a perfectly acceptable answer. I've run into this many times when working with custom UI. The most recent example is that I'm trying to replace the UINavigationItem plain-text title with a custom view. I want that view to fill the superview, but in addition, I want a UIActivityIndicatorView on the right side, inset about 2 pixels and centered vertically. Here's the code: - (void) viewDidLoad { [super viewDidLoad]; customTitleView = [[UIView alloc] initWithFrame:CGRectZero]; customTitleView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth; titleLabel = [[UILabel alloc] initWithFrame:CGRectZero]; titleLabel.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth; titleLabel.lineBreakMode = UILineBreakModeWordWrap; titleLabel.numberOfLines = 2; titleLabel.minimumFontSize = 11.0; titleLabel.font = [UIFont systemFontOfSize:17.0]; titleLabel.adjustsFontSizeToFitWidth = YES; [customTitleView addSubview:titleLabel]; spinnerView = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite]; spinnerView.center = CGPointMake(customTitleView.bounds.size.width - (spinnerView.bounds.size.width / 2) - 2, customTitleView.bounds.size.height / 2); spinnerView.hidesWhenStopped = YES; [customTitleView addSubview:spinnerView]; self.navigationItem.titleView = customTitleView; [customTitleView release]; } Here's my problem: at the time that this code runs, customTitleView.bounds is still zeroes. The auto-resizing mask hasn't had a chance to do its thing yet, but I very much want those values so that I can compute the relative positions of other sub-views (here, the activity indicator). Is this possible without being ugly?

How can I change the language of dynamic text in a SWF using flashvars?

- by Cormac

I have a SWF with text embedded from an external .txt file. Is there a way I can have a different file used as the text source through the embedcode (swfObject) depending on the language? Here is my current actionscript: myData = new LoadVars(); myData.onLoad = function() { text_clips.project_title.text = this.projecttitle1; }; myData.load("translatetext.txt"); var loader:MovieClipLoader = new MovieClipLoader(); loader.loadClip(_level0.projectimage1,pic1.image_holder); This is the content of translatetext.txt: projecttitle1=This is my translatable text This is the embed code I'm using: <div> <object width="960" height="275" id="rvFlashcontent"> <param name="movie" value="lang_test_3.swf" /> <param name="wmode" value="transparent" /> <param name="flashvars" value="projectimage1=flashimages/testimage.jpg" />  <object type="application/x-shockwave-flash" data="lang_test_3.swf" width="960" height="275"> <param name="wmode" value="transparent" /> <param name="flashvars" value="projectimage1=flashimages/testimage.jpg" />  <h1>Alt Content</h1>  </object>  </object> </div> What I want to do is add a Flashvars parameter to name the file to load, so I can change the language: <param name="flashvars" value="projectimage1=flashimages/image.jpg&projecttext=textfrench.txt" /> There are four languages needed so far, but this will grow so it needs to be flexible enough to let the developers add languages without getting a new SWF each time. Thanks in advance all!

Actionscript: How Can I Know When The Source Property Of An Image Is Completely Updated

- by Joshua

var I:Image=new Image(); I.source='C:\\Abc.png'; var H:int=I.height; H is always Zero! I am presuming this is because the image hasn't finished reading the png file off the disk yet. What event can I monitor to know when it's width and height will have the right values? The 'Complete' event only seems to work for DOWNLOADED images. The 'Render' event happens EVERY FRAME. The (undocumented?) 'sourceChanged', happens as soon as source changes, and has the same problem! What event do I watch that will let me know when the image's width and height properties will have valid values? Or is there some Synchronous version of I.source='xxx.png', that I don't know about? P.S. Yes, I know I shouldn't use "C:\" in an Air Program. This was just for illustrative purposes, so that you won't suggest I use "Complete", which never even seems to fire when the file indicated by source is local.

Why would an image (the Mandelbrot) be skewed and wrap around?

- by Sean D

So I just wrote a little snippet to generate the Mandelbrot fractal and imagine my surprise when it came out all ugly and skewed (as you can see at the bottom). I'd appreciate a point in the direction of why this would even happen. It's a learning experience and I'm not looking for anyone to do it for me, but I'm kinda at a dead end debugging it. The offending generation code is: module Mandelbrot where import Complex import Image main = writeFile "mb.ppm" $ imageMB 1000 mandelbrotPixel x y = mb (x:+y) (0:+0) 0 mb c x iter | magnitude x > 2 = iter | iter >= 255 = 255 | otherwise = mb c (c+q^2) (iter+1) where q = x --Mandelbrot --q = (abs.realPart $ x) :+ (abs.imagPart $ x) --Burning Ship argandPlane x0 x1 y0 y1 width height = [(x,y)| y<-[y1,(y1-dy)..y0], --traverse from x<-[x0,(x0+dx)..x1]] --top-left to bottom-right where dx = (x1 - x0)/width dy = (y1 - y0)/height drawPicture :: (a->b->c)->(c->Colour)->[(a,b)]->Image drawPicture function colourFunction plane = map (colourFunction.uncurry function) plane imageMB s = createPPM s s $ drawPicture mandelbrotPixel (\x->[x,x,x]) $ argandPlane (-1.8) (-1.7) (0.02) 0.055 s' s' where s' = fromIntegral s And the image code (which I'm fairly confident in) is: module Image where type Colour = [Int] type Image = [Colour] createPPM :: Int -> Int -> Image -> String createPPM w h i = concat ["P3 ", show w, " ", show h, " 255\n", unlines.map (unwords.map show) $ i]

TableLayout formatting loss after device rotation

- by roundhill

I'm seeing a strange issue with a TableLayout after the device is rotated from either orientation. If you load the view in either portrait or landscape mode, the table loads fine. But once you rotate the device, the columns collapse to just fit their width. I would expect that after rotation, the columns would still stretch to fit the width of the screen. Any ideas on what can be done to resolve this? Screenies and layout code below. Before Rotation: After Rotation: Table Layout: <TableLayout android:id="@+id/dataTable" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1" android:layout_below="@id/chart" android:stretchColumns="*" android:shrinkColumns="*" android:padding="6dip" > </TableLayout> Table Row: <TableRow xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TextView android:id="@+id/col1" android:layout_marginRight="2dip" android:textColorLink="#FF21759b" android:text="Column 1" android:padding="4dip" android:textColor="#FF464646"/> <TextView android:id="@+id/col2" android:text="Column 2" android:textColor="#FF464646" android:padding="4dip"/> </TableRow> Thanks!

Include php code within echo from a random text

- by lisa

I want to display a php code at random and so for I have <?php // load the file that contain thecode $adfile = "code.txt"; $ads = array(); // one line per code $fh = fopen($adfile, "r"); while(!feof($fh)) { $line = fgets($fh, 10240); $line = trim($line); if($line != "") { $ads[] = $line; } } // randomly pick an code $num = count($ads); $idx = rand(0, $num-1); echo $ads[$idx]; ?> The code.txt has lines like <?php print insert_proplayer( array( "width" => "600", "height" => "400" ), "http://www.youtube.com/watch?v=xnPCpCVepCg"); ?> Proplayer is a wordpress plugin that displays a video. The codes in code.txt work well, but not when I use the pick line from code.txt. Instead of the full php line I get: "width" => "600", "height" => "400" ), "http://www.youtube.com/watch?v=xnPCpCVepCg"); ?> How can I make the echo show the php code, rather than a txt version of the php code?
