  • Yii file upload issue

    - by user1289853
    Couple of months ago,I developed a simple app using YII,one of the feature was to upload file. The feature was working well in my dev machine,couple of days ago client found the file upload feature is not working in his server since deployment. And after that I test my dev machine that was not working too. My controller looks: public function actionEntry() { if (!Yii::app()->user->isGuest) { $model = new TrackForm; if (isset($_POST['TrackForm'])) { $entry = new Track; try { $entry->product_image = $_POST['TrackForm']['product_image']; $entry->product_image = CUploadedFile::getInstance($model, 'product_image'); if ($entry->save()) { if ($entry->product_image) { $entry->product_image->saveAs($entry->product_image->name, '/trackshirt/uploads'); } } $this->render('success', array('model' => $model)); // redirect to success page } } catch (Exception $e) { echo 'Caught exception: ', $e->getMessage(), "\n"; } } else { $this->render('entry', array('model' => $model)); } } } Model is like below: <?php class Track extends CActiveRecord { public static function model($className=__CLASS__) { return parent::model($className); } public function tableName() { return 'product_details'; } } My view looks: <?php $form = $this->beginWidget('CActiveForm', array( 'id' => 'hide-form', 'enableClientValidation' => true, 'clientOptions' => array( 'validateOnSubmit' => true, ), 'htmlOptions' => array('enctype' => 'multipart/form-data'), )); ?> <p class="auto-style2"><strong>Administration - Add New Product</strong></p> <table align="center" style="width: 650px"><td class="auto-style3" style="width: 250px">Product Image</td> <td> <?php echo $form->activeFileField($model, 'product_image'); ?> </td> </tr> </table> <p class="auto-style1"> <div style="margin-leftL:-100px;"> <?php echo CHtml::submitButton('Submit New Product Form'); ?> </div> <?php $this->endWidget(); ?> Any idea where is the problem?I tried to debug it but every time it returns Null. Thanks.

  • Passing operator as a parameter

    - by nacho4d
    Hi, I want to have a function that evaluates 2 bool vars (like a truth table) for example: since T | F : T then myfunc('t', 'f', ||); /*defined as: bool myfunc(char lv, char rv, ????)*/ should return true; how can I pass the third parameter? (I know is possible to pass it as a char* but then I will have to have another table to compare operator string and then do the operation which is something I would like to avoid) Is it possible to pass an operator like ^(XOR) or ||(OR) or &&(AND), etc in a function/method? Thanks in advance

  • Can I use this Ajax script to communicate and exchange data between client and server?

    - by lala
    This block of code is for client.html (it is located in this www.client.com/client.html) - client side. The I have the code below that goes something like this: ajaxRequest.open("GET", "http://www.server.com/ajax.php", true); This is how I call the file ajax.php located in the server. Unfortunately I have no luck at all. It cannot connect to the server I'm calling. BTW, the ips /test site I've been using are all no restrictions, and is accessible to all. However, I tried to simulate by putting both client.html and ajax.php in same site and it works well. So my question is does this script works only if you are in same site? or does it work also in client-server scenario? What else do I have to do in order to make this work? //client.html <script language="javascript" type="text/javascript"> <!-- //Browser Support Code function ajaxFunction(){ var ajaxRequest; // The variable that makes Ajax possible! try{ // Opera 8.0+, Firefox, Safari ajaxRequest = new XMLHttpRequest(); } catch (e){ // Internet Explorer Browsers try{ ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { try{ ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP"); } catch (e){ // Something went wrong alert("Your browser broke!"); return false; } } } // Create a function that will receive data sent from the server ajaxRequest.onreadystatechange = function(){ if(ajaxRequest.readyState == 4){ document.myForm.time.value = ajaxRequest.responseText; } } ajaxRequest.open("GET", "http://www.server.com/ajax.php", true); ajaxRequest.send(null); } //--> </script> <form name='myForm'> Name: <input type='text' onChange="ajaxFunction();" name='username' /> <br /> Time: <input type='text' name='time' /> </form> </body> </html> // ajax.php <?php echo date("H:i:s"); ?>

  • How do I convert an arbitrary list of strings to a SQL rowset?

    - by Jim Kiley
    I have a simple list of strings, which may be of arbitrary length. I'd like to be able to use this list of strings as I would use a rowset. The app in question is running against SQL Server. To be clearer, if I do SELECT 'foo', 'bar', 'baz' I get 'foo', 'bar', and 'baz' as fields in a single row. I'd like to see each one of them as a separate row. Is there a SQL (or SQLServer-specific) function or technique that I'm missing, or am I going to have to resort to writing a function in an external scripting language?

  • Can a process have two pid's?

    - by limp_chimp
    I'm studying computer systems and I've made this very simple function which uses fork() to create a child process. fork() returns a pid_t that is 0 if it's a child process. But calling the getpid() function within this child process returns a different, nonzero pid. In the code I have below, is newPid only meaningful in the context of the program, and not to the operating system? Is it possibly only a relative value, measured against the pid of the parent? #include <stdio.h> #include <unistd.h> #include <sys/types.h> #include <string.h> #include <errno.h> #include <stdlib.h> void unixError(char* msg) { printf("%s: %s\n", msg, strerror(errno)); exit(0); } pid_t Fork() { pid_t pid; if ((pid = fork()) < 0) unixError("Fork error"); return pid; } int main(int argc, const char * argv[]) { pid_t thisPid, parentPid, newPid; int count = 0; thisPid = getpid(); parentPid = getppid(); printf("thisPid = %d, parent pid = %d\n", thisPid, parentPid); if ((newPid = Fork()) == 0) { count++; printf("I am teh child. My pid is %d, my other pid is %d\n", getpid(), newPid); exit(0); } printf("I am the parent. My pid is %d\n", thisPid); return 0; } Output: thisPid = 30050, parent pid = 30049 I am the parent. My pid is 30050 I am teh child. My pid is 30052, my other pid is 0 Lastly, why is the child's pid 2 higher than the parent's, and not 1? The difference between the main function's pid and its parent is 1, but when we create a child it increments the pid by 2. Why is that?

  • Google Map + MarkerClusterer only takes place when map completely zooms out

    - by user415795
    The clustering works but somehow it only takes place at the maximum zoom out(the largest view with all nations), the moment I zoom in by 1 value, the clustering icon changes back to markers. I try with all kinds of values on the maxZoom and gridSize clusterer options with no help. Can someone please kindly advice. Thanks. <script language="javascript" type="text/javascript"> var markersArray = []; var mc = null; var markersArray = []; var mc = null; var map; var mapOptions; var geocoder; var infoWindow; var http_request = false; var lat = 0; var lng = 0; var startingZoom = 7; var lowestZoom = 1; // The lower the number, the more places can be seen on within the bounds. var highestZoom = 8; function mapLoad() { geocoder = new google.maps.Geocoder(); infoWindow = new google.maps.InfoWindow(); mapOptions = { zoomControl: true, zoom: 2, minZoom: lowestZoom, maxzoom: highestZoom, draggable: true, scrollwheel: true, disableDoubleClickZoom: true, mapTypeId: google.maps.MapTypeId.ROADMAP }; map = new google.maps.Map(document.getElementById('map'), mapOptions); } $(document).ready(function () { var searchUrl; var locations; // Place the user's current location marker on the map var Location = new google.maps.LatLng(1.340319, 103.743744); var Location2 = new google.maps.LatLng(1.322347, 103.757881); createMarker('1', Location, 'My Location', '', '', '', '/Images/home.png'); createMarker('1', Location2, 'My Location', '', '', '', '/Images/bb.png'); var bounds = new google.maps.LatLngBounds(); bounds.extend(gameLocation); map.fitBounds(bounds); }); // Create the marker with address information function createMarker(actId, point, address1, address2, town, postcode, icon) { var marker = new google.maps.Marker({ map: map, icon: icon, position: point, title: address1, animation: google.maps.Animation.DROP }); marker.metadata = { id: actId }; markersArray.push(marker); mc = new MarkerClusterer(map, markersArray); return marker; } </script>

  • jQuery access each matched element from '.find' by an index

    - by GHarping
    Using jQuery's .find() method to return a set of elements, I am trying to access items in the returned set by their order in that set. For example, a table with two rows and in each row a select box and two text input fields, accessed with the following: $('table#tbl').find('tr.row').each(function(i) { }); To get the first element I would have thought I could use $('table#tbl').find('tr.row').each(function(i) { alert( $(this).find(':input').get(1).val() ); }); And variations of the above, but apparently this doesn't work. Could anyone suggest the correct method to access item x of n elements returned?

  • Optional URL fragment in Codeigniter?

    - by DA
    This is maybe a simple syntax question or possibly a best-practices question in terms of codeigniter. I should start by saying I'm not a PHP or Codeigniter person so trying to get up to speed on helping on a project. I've found the CI documentation fairly good. The one question I can't find an answer to is how to make part of a URL optional. An example the CI documentation uses is this: example.com/index.php/products/shoes/sandals/123 and then the function used to parse the URI: function shoes($sandals, $id) For my example, I'd like to be able to modify the URL as such: example.com/index.php/products/shoes/all So, if no ID is passed, it's just ignored. Can that be done? Should that be done? A second question unrelated to my problem but pertaining to the example above, why would the variable $sandals be used as in the example, the value is 'sandals'? Shouldn't that variable be something like $shoetype?

  • Access to bytes array of a Bitmap

    - by Deulis
    1- In Windows CE, I have a Bitmap object in C#. 2- I have a C function in an extern dll that expects as parameters the pointer to a bytes array that represents an image in RGB565 format, width and height. This function will draw on this array of bytes. So I need to pass the byte array pointer of the Bitmap object, but I can find a practical way to get this pointer. One way is convert this Bitmap into a bytes array using a memory stream or something else, but it will create a new bytes array, so I will keep in memory both object, the Bitmap and the bytes array, but I don’t want it because the few available memory, that’s why I need to access to the bytes array of the bitmap object, not create a new bytes array. Anyone can help me?

    hi, my situation is the following: i have a datareader and loop over all records returned by a select statement and then call a function with a value from that row. but now i need to update a column in each row, after the function has been called. using a separate update statement seems like a huge overkill. what's the best method to do so? i've heard about dataadapters and datasets—but the only thing i know is that they exist, not how to use them (properly) in this case. platform is c# with sql server

  • JqueryUI Tab Linking from Another Page

    - by pschorr
    I'm having some issues with jqueryui tabs and linking to certain tabs on another page. Basically, each page has tabs, and all are navigational via drop down at the top, with each 'tab' being available in the drop down. Currently I'm able to text-link, but only within the page I'm on, and I'm just lost on the getting it to work correctly from page to page. Here's what I currently got working with internal text link. $(function() { $("#tabs").tabs( {fx: { opacity: 'toggle' }, selected: 0} ); var $tabs = $('#tabs').tabs(); // first tab selected $('a.nutrlink').click(function() { // bind click event to link $tabs.tabs('select', 1); // switch to third tab return false; }); });

  • Row/column counter in 'apply' functions

    - by mortalitysequence
    What if one wants to apply a functon i.e. to each row of a matrix, but also wants to use as an argument for this function the number of that row. As an example, suppose you wanted to get the n-th root of the numbers in each row of a matrix, where n is the row number. Is there another way (using apply only) than column-binding the row numbers to the initial matrix, like this? test <- data.frame(x=c(26,21,20),y=c(34,29,28)) t(apply(cbind(as.numeric(rownames(test)),test),1,function(x) x[2:3]^(1/x[1]))) P.S. Actually if test was really a matrix : test <- matrix(c(26,21,20,34,29,28),nrow=3) , rownames(test) doesn't help :( Thank you.

  • Appending target="_blank" to links in an iframe without using <body onload>

    - by CincauHangus
    I'm trying to change the links in an iframe to load in a new window instead of the iframe itself. Currently I use this code in head: $(document).ready(function() { var oIFrame = document.getElementById("iframeID"); var oDoc = (oIFrame.contentWindow || oIFrame.contentDocument); if(oDoc.document) oDoc = oDoc.document; var links = oDoc.getElementsByTagName("a"); for(var i=0; i<links.length; i++) { links[i].target="_blank"; } }); However, the code above is triggered before the iframe is fully loaded with its contents. I know this code would work if it's triggered in the body onload attribute, but I'd like to avoid that method and implement it in a function or a file instead.

  • JQuery UI Tabs widget error handling

    - by dthrasher
    When an ajax request fails, the JQuery UI Tabs widget stops responding and the "Loading..." spinner remains on the tab that caused the error. I can get the ajax callback to give me some sort of alert message like so: $('#localtabs > ul').tabs({ ajaxOptions: { success: tabLoadSuccessCallback, error: tabLoadFailureCallback} }); function tabLoadSuccessCallback(XMLHttpRequest, textStatus, errorThrown) { alert("Yay!");} function tabLoadFailureCallback(XMLHttpRequest, textStatus, errorThrown) { alert("Could not get search results.");} But what I'd really like is to be able to display a message within the panel, cancel the spinner, and disable the tab that caused the problem while leaving the rest of the tabs operational. Does anyone have any ideas for how to do this?

  • How prevent anyone from stealing my shared_ptr?

    - by Kyle
    So, I use boost::shared_ptr for all the various reference-counting benefits it provides -- reference counting for starters, obviously, but also the ability to copy, assign, and therefore store in STL Containers. The problem is, if I pass it to just one "malicious" function or object, the object can save the ptr and then I'll never be able to de-allocate it without the foreign function or object nicely relinquishing its ownership. Ultimately, I try to keep object ownership explicit. I accomplish this by having the owner keep the only shared_ptr to the object, and "guest" objects only store weak_ptrs to the object. I really don't want the "shared" part of shared_ptr, but I'm required to use shared_ptr in order to make weak_ptrs. I want to use scoped_ptr, but it's extremely limited since you can't copy it. You can't store it in a container, you can't lend out weak_ptrs from it, and you can't transfer ownership to a new manager. What's the solution?

  • misleading plot issue in mathematica

    - by Qiang Li
    I want to study some "strange" functions by plotting them out in mathematica. One example is the following: mod2[x_] := Which[Mod[x, 2] >= 1, -2 + Mod[x, 2], True, Mod[x, 2]]; f[x_] := Which[-1 <= x <= 1, Abs[x], True, Abs[mod2[x]]]; fn[x_, n_] := Sum[(3/4)^i*f[4^n*x], {i, 0, n}] Plot[{fn[x, 0], fn[x, 1], fn[x, 2], fn[x, 5]}, {x, -2, 2}] However, the plot I got from mma is misleading, in the sense that the maxima and minima of fn[x, 5] should be on the same two levels. But due to high oscillation of the function, and the fact that clearly mma only takes limited number of points to draw the function, you see the plot exhibit strange behavior. Is there any option in plot to remedy for this? Many thanks.

  • find lowest neighbor matlab

    - by user1812719
    I am trying to write a function [offset,coffset]=findLowNhbr(map) that for each pixel in a map finds the eight neighbors to the pixel, and returns two matrices with both the row and column offsets to the lowest neighbor (uses the numbers -1, 0 and 1). Border pixels are given 0 offsets for both the row and column, since they do not have neighbors. Here is what I think the general plan for this function should be: For each point, find the eight nearest neighbors. If the neighbor is lower than the point, return -1 If the neighbor is at the same elevation as the point, return 0 If the neighbor is higher than the point, return +1 Store these offsets in two matrices. I am at a complete loss as to where to start, so any advice or questions are welcome!
