  • PHP: Formatting multi-dimensional array as HTML?

    - by Industrial
    Hi everybody, I have tried to get my head around building a recursive function to handle formatting of a unknown depth multi-dimensional array to HTML and nested Divs. I thought that it should be a piece of cake, but no. Here's what I have come up with this far: function formatHtml($array) { $var = '<div>'; foreach ($array as $k => $v) { if (is_array($v['children']) && !empty($v['children'])) { formatHtml($v['children']); } else { $var .= $v['cid']; } } $var.= '</div>'; return $var; } And here's my array: Array ( [1] => Array ( [cid] => 1 [_parent] => [id] => 1 [name] => 'Root category' [children] => Array ( [2] => Array ( [cid] => 2 [_parent] => 1 [id] => 3 [name] => 'Child category' [children] => Array () ) ) ) ) Thanks a lot!

  • Echoing variable construct instead of content

    - by danp
    I'm merging two different versions of a translations array. The more recent version has a lot of changes, over several thousand lines of code. To do this, I loaded and evaluated the new file (which uses the same structure and key names), then loaded and evaluated the older version, overwriting the new untranslated values in the array with the values we already have translated. So far so good! However, I want to be able to echo out the constructor for this new merged array so I can cut and paste it into the new translation file, and have job done (apart from completing the rest of the translations..). The code looks like this (lots of different keys, not just index): $lang["index"]["chart1_label1"] = "Subscribed"; $lang["index"]["chart1_label2"] = "Unsubscribed"; And the old.. $lang["index"]["chart1_label1"] = "Subscrito"; $lang["index"]["chart1_label2"] = "Não subscrito"; After loading the two files, I end up with a merged $lang array, which I then want to echo out in the same form, so it can be used by the project. However, when I do something like this.. foreach ($lang as $key => $value) { if (is_array($value)) { foreach ($value as $key2 => $value2) { echo "$lang['".$key."']"; // ... etc etc } } } ..obviously I get "ArrayIndex" etc etc instead of "$lang". How to echo out $lang without it being evaluated..? Once this is working, can add in the rest of the brackets etc (I realise they are missing), but just want to make this part work first. If there's a better way to do this, all ears too! Thanks.

  • Is there any way to pass an anonymous array as an argument in C++?

    - by Jeremy Friesner
    Hi all, I'd like to be able to declare an array as a function argument in C++, as shown in the example code below (which doesn't compile). Is there any way to do this (other than declaring the array separately beforehand)? #include <stdio.h> static void PrintArray(int arrayLen, const int * array) { for (int i=0; i<arrayLen; i++) printf("%i -> %i\n", i, array[i]); } int main(int, char **) { PrintArray(5, {5,6,7,8,9} ); // doesn't compile return 0; }

  • Fatal error: Cannot use string offset as an array

  • Looping through NSArray while subtracting values from each object? [on hold]

    - by Julian
    I have NSNumber objects stored in an NSMutableArray. I am attempting to perform a calculation on each object in the array. What I want to do is: 1) Take a random higher number variable and keep subtracting a smaller number variable in increments until the value of the variable is equal to the value in the array. For example: NSMutableArray object is equal to 2.50. I have an outside variable of 25 that is not in the array. I want to subtract 0.25 multiple times from the variable until I reach less than or equal to 2.50. I also need a parameter so if the number does not divide evenly and goes below the array value, it resorts to the original array value of 2.50. Lastly, for each iteration, I want to print the values as they are counting down as a string. I was going to provide code, but I don't want to make this more confusing than it has to be. So my output would be: VALUE IS: 24.75 VALUE IS: 24.50 VALUE IS: 24.25 … VALUE IS: 2.50 END

  • How do I add values in an array when there is a null entry?

    - by Angela
    I want to create a real time-series array. Currently, I am using the statistics gem to pull out values for each 'day': define_statistic :sent_count, :count => :all, :group => 'DATE(date_sent)', :filter_on => {:email_id => 'email_id > = ?'}, :order => 'DATE(date_sent) ASC' What this does is create an array where there are values for a date, for example [["12-20-2010",1], ["12-24-2010",3]] But I need it to fill in the null values, so it looks more like: [["12-20-2010",1], ["12-21-2010",0], ["12-22-2010",0], ["12-23-2010",0], ["12-24-2010",3]] Notice how the second example has "0" values for the days that were missing from the first array.

  • Convert PHP array into Key => Value Array

    - by Feature
    Total PHP Noob and I couldn't find an answer to this specific problem. Hope someone can help! $myvar is an array that looks like this: Array ( [aid] = Array ( [0] = 2 [1] = 1 ) [oid] = Array( [0] = 2 [1] = 1 ) ) And I need to set a new variable (called $attributes) to something that looks like this: $attributes = array($myvar['aid'][0] => $myvar['oid'][0], $myvar['aid'][1] => $myvar['oid'][1], etc...); And, of course, $myvar may contain many more items... How do I iterate through $myvar and build the $attributes variable?

  • How to update content of one ArrayController from the selected value of another ArrayController in Ember.js

    - by CodeHugger
    I have the following problem in ember.js. A child controller depends on a selected value in a parent controller in order to determine its content. In the database a child has a parent_id reference. App.parentsController = Em.ArrayController.create({ content: [], selected: null }); App.sonsController = Em.ArrayController.create({ // the value of content depends on the id of // the selected item in the parentsController content: [], selected: null }); App.daughtersController = Em.ArrayController.create({ // the value of content depends on the id of // the selected item in the parentsController content: [], selected: null }); I would prefer to solve this without the parentsController having to know anything about the other controllers. This should be possible with observers, bindings or even through calculations but I have no clue where to start. Any help would be well appreciated.

  • c# Wrapper to native c++ code, wrapping a parameter which is a pointer to an array

    - by mb300dturbo
    Hi, I have the following simple DLL in c++ un-managed code; extern "C" __declspec(dllexport) void ArrayMultiplier(float (*pointerArray)[3], int scalar, int length); void ArrayMultiplier(float (*pointerArray)[3], int scalar, int length) { for (int i = 0 ; i < length ; length++) { for (int j = 0; j < 3; j++) { pointerArray[i][j] = pointerArray[i][j] * scalar; } } } I have tried writing the following wrapper function for the above in c#: [DllImport("sample.dll")] public static extern void ArrayMultiplier(ref float elements, int scalar, int length); where elements is a 2 dimentional 3x3 array: public float[][] elements = { new float[] {2,5,3}, new float [] {4,8,6}, new float [] {5,28,3} }; The code given above compiles, but the program crashes when the wrapper function is called: Wrapper.ArrayMultiplier(ref elements, scalar, length); Please help me here, and tell me whats wrong with the code above, or how a wrapper can be written for a simple c++ function: void SimpleFunction(float (*pointerToArray)[3]); Thank you all in advance

  • Another php array looping question

    - by Dan
    Been battling with this one for what seems, like forever. I have an array: $url_array It contains this info: Array ( [ppp] => Array ( [0] => stdClass Object ( [id] => 46660 [entity_id] => 0 [redirect_url] => http://www.google.com [type] => Image ) [1] => stdClass Object ( [id] => 52662 [entity_id] => 0 [pixel_redirect_url] => http://www.yahoo.com [type] => Image ) [2] => stdClass Object ( [id] => 53877 [entity_id] => 0 [redirect_url] => http://www.msn.com [pixel_type] => Image ) ) [total_count] => 3 ) I need to loop through it, and do things to each variable. I can get this to work: foreach ($piggies_array as $key => $value) { $id = $value[0]->id; $redirect_url = $value[0]->redirect_url; } Not unsurprisingly, it's only echoing the first value of those variables, but no matter what I try I cannot get it to loop through: $value->redirect_url; $value=>redirect_url; I would appreciate any help.

  • Shortest Distance From An Array

    - by notyou61
    I have an ajax function which returns the latitudes and longitudes of locations stored in a database. These are returned and placed in an array. A calculation is performed to return their distance from the users current location based on the latitude/longitude. I would like to return only the record with the shortest calculated distance. My code is as follows: Ajax Success // Success success: function (data) { // Obtain Log/Lat navigator.geolocation.getCurrentPosition(function(position) { // Obtain Current Position Lat/Lon glbVar.latitude = position.coords.latitude; glbVar.longitude = position.coords.longitude; // Console Log //console.log('Lat: ' + glbVar.latitude + ' Lon: ' + glbVar.longitude); // Obtain Location Distances for ( var i = 0; i < data.length; i++ ) { // Location Instances var varLocation = data[i]; // Location Distance varLocation.distance = calculateDistance(glbVar.longitude, glbVar.latitude, varLocation.locationLongitude, varLocation.locationLatitude); } // Sort Locations By Distance var sortedData = data.sort(function(a, b) { // Return Locations return a.distance - b.distance; }); // Output Results $.map(sortedData, function(item) { // Obtain Location Distance varLocationsDistance = calculateDistance(glbVar.longitude, glbVar.latitude, item.locationLongitude, item.locationLatitude); // Obtain Location Radius Assignment if (varLocationsDistance <= varLocationRadius) { // Function Return functionReturn = $({locationID : item.locationID + ', Distance : ' + varLocationsDistance + ' m'}); // Return // Function to get the Min value in Array Array.min = function( sortedData ){ functionReturn = Math.min.apply( Math, sortedData ); // console.log(functionReturn); }; } }); }); } The calculateDistance function returns the distance from the users current location and those from the database. The varLocationsDistance <= varLocationRadius "If" statement returns records within a certain distance radius (100 meters), within that statement I would like to return the shortest distance. I am a self taught amateur web developer and as a result may not have provide enough information for an answer, please let me know. Thanks,

  • Is this the correct way to reloadData on a UITableView?

    - by Sheehan Alam
    I am trying to append objects to my data source and then reload the table. Is this the correct way of approaching it? self.items is my datasource //Copy current items self.itemsCopy = [self.items mutableCopy];//[[NSMutableArray alloc] initWithArray:self.items copyItems:NO]; NSLog(@"Copy Size before append: %d",[itemsCopy count]); //Get new items int lastMsgID = [self getLastMessageID]; [self.coreData getMoreMessages:self.title lastID:lastMsgID]; //This will update self.items with 30 objects //Append new items [itemsCopy addObjectsFromArray:self.items]; //Empty items and copy itemsCopy [self.items removeAllObjects]; self.items = [self.itemsCopy mutableCopy]; NSLog(@"Actual Size after append: %d",[self.items count]); //Reload data [tableView reloadData];

  • Append to the end of a Char array in C++

    - by Taylor Huston
    Is there a command that can append one array of char onto another? Something that would theoretically work like this: //array1 has already been set to "The dog jumps " //array2 has already been set to "over the log" append(array2,array1); cout << array1; //would output "The dog jumps over the log"; This is a pretty easy function to make I would think, I am just surprised there isn't a built in command for it. *Edit I should have been more clear, I didn't mean changing the size of the array. If array1 was set to 50 characters, but was only using 10 of them, you would still have 40 characters to work with. I was thinking an automatic command that would essentially do: //assuming array1 has 10 characters but was declared with 25 and array2 has 5 characters int i=10; int z=0; do{ array1[i] = array2[z]; ++i; ++z; }while(array[z] != '\0'); I am pretty sure that syntax would work, or something similar.

  • Passing an array of an array of char to a function

    - by L.A. Rabida
    In my program, I may need to load a large file, but not always. So I have defined: char** largefilecontents; string fileName="large.txt"; When I need to load the file, the program calles this function: bool isitok=LoadLargeFile(fileName,largefilecontents); And the function is: bool LoadLargeFile(string &filename, char ** &lines) { if (lines) delete [] lines; ifstream largeFile; #ifdef LINUX largeFile.open(filename.c_str()); #endif #ifdef WINDOWS largeFile.open(filename.c_str(),ios::binary); #endif if (!largeFile.is_open()) return false; lines=new char *[10000]; if (!lines) return false; largeFile.clear(); largeFile.seekg(ios::beg); for (int i=0; i>-1; i++) { string line=""; getline(largeFile,line); if (largeFile.tellg()==-1) break; //when end of file is reached, tellg returns -1 lines[i]=new char[line.length()]; lines[i]=const_cast<char*>(line.c_str()); cout << lines[i] << endl; //debug output } return true; } When I view the debug output of this function, "cout << lines[i] << endl;", it is fine. But when I then check this in the main program like this, it is all messed up: for (i=0; i<10000; i++) cout << largefilecontents[i] << endl; So within the function LoadLargeFile(), the results are fine, but without LoadLargeFile(), the results are all messed up. My guess is that the char ** &lines part of the function isn't right, but I do not know what this should be. Could someone help me? Thank you in advance!

  • Get values from HTML in a multidimensional array and calculate values using PHP

    - by Frank Nwoko
    I have searched but could not get solution on this issue. I am working on an application which will generate unknown number of items and have users select the quantity from a drop down against each item. Eg. Item(s) | price | Select qty Rice 23 3 Beans 22 4 Eggs 52 5 ... ... ... unknown Please, how can I capture the above in an array and also calculate the total value for all selected items and corresponding fees? I have the following HTML code: <form id='form1' name='form1' method='post' action='item_calc.php'> <?php ..... while($t_row = mysql_fetch_assoc($get_items)) { echo "<p><label>$t_row['$item_name'] <input type='text' READONLY name='item_price[]' value='$t_row['$item_price']' /></label> <input type='text' READONLY name='item_fees[]' value='$t_row['$item_fee']' /> <select name="item_qty"> <option value="1"> <option value="2"> <option value="3"> <option value="4"> <option value="5"> </select> </p><p>"; } echo "<label><input type='submit' name='submit' value='Submit' /></label></p> </form>"; Please, how can I get item_price[] + item_fees[] * item_qty for all selected items? This is what I have tried: for ($i = 0; $i < count($_POST['item_price']); $i++) { // Do something here with $_POST['checkbx'][$i] foreach ($_POST['item_fees'] as $tkey => $tvalue) { //echo "Key: $tkey; Value: $tvalue<br>"; } foreach ($_POST['item_price'] as $pkey => $pvalue) { //echo "Key: $pkey; Value: $pvalue<br>"; } $total = $tvalue + $pvalue; } echo $total;
