  • jquery ajax and php arrays

    - by sea_1987
    Hi There, I am trying to submit some data to a PHP script, however the PHP scripts expects the data to arrive in a specific format, like this example which is a dump of the post, Array ( [save] => Add to shortlist [cv_file] => Array ( [849709537] => Y [849709616] => Y [849709633] => Y ) ) The process is currently that a user selects the product they want using checkboxes and then clicks a submit button which fires the PHP scripts, The HTML looks like this, div class="row"> <ul> <li class="drag_check ui-draggable"> <input type="checkbox" id="inp_cv_849709537" name="cv_file[849709537]" class="cv_choice" value="Y"> </li> <li class="id"><a href="/search/cv/849709537">849709537</a></li> <div class="disp"> <li class="location">Huddersfield</li> <li class="status"> Not currently working </li> <li class="education">other</li> <li class="role"> Temporary </li> <li class="salary">£100,000 or more</li> <div class="s">&nbsp;</div> </div> </ul> <dl> <dt>Current Role</dt> <dd>Developer </dd> <dt>Sectors</dt><dt> </dt><dd> Energy &amp; Utilities, Healthcare, Hospitality &amp; Travel, Installation &amp; Maintenance, Installation &amp; Maintenance </dd> <dt>About Me</dt><dt> </dt><dd></dd> </dl> <div class="s"></div> </div> I am needing to use AJAX instead now, but I need to send the data to PHP in the format it expects here is what I have so far, $('#addshortlist').click(function() { var datastring = ui.draggable.children().attr('name')+"="+ui.draggable.children().val()+"&save=Add to shortlist"; alert(datastring); $.ajax({ type: 'POST', url: '/search', data:ui.draggable.children().attr('name')+"="+ui.draggable.children().val()+"&save=Add to shortlist", success:function(){ alert("Success"+datastring); }, error:function() { alert("Fail"+datastring); } }); return false; }); I would really appreciate any help

  • Are variable length arrays possible with Javascript

    - by Ankur
    I want to make a variable length array in Javascript. Is this possible. A quick google search for "Javascript variable length array" doesn't seem to yield anything, which would be surprising if it were possible to do this. Should I instead have a String that I keep appending to with a separator character instead, or is there a better way to get a varible length array-like variable.

  • removing pairs of elements from numpy arrays that are NaN (or another value) in Python

    - by user248237
    I have an array with two columns in numpy. For example: a = array([[1, 5, nan, 6], [10, 6, 6, nan]]) a = transpose(a) I want to efficiently iterate through the two columns, a[:, 0] and a[:, 1] and remove any pairs that meet a certain condition, in this case if they are NaN. The obvious way I can think of is: new_a = [] for val1, val2 in a: if val2 == nan or val2 == nan: new_a.append([val1, val2]) But that seems clunky. What's the pythonic numpy way of doing this? thanks.

  • Confused about copying Arrays in Objective-C

    - by Sheehan Alam
    Lets say I have an array X that contains [A,B,C,D,nil]; and I have a second array Y that contains [E,F,G,H,I,J,nil]; If I execute the following: //Append y to x [x addObjectsFromArray:y]; //Empty y and copy x [y removeAllObjects]; y = [x mutableCopy]; What is the value of y? is it?: [A,B,C,D,E,F,G,H,I,J,nil] Am I performing the copy correctly?

  • Looping through JSON arrays

    - by George
    I'm trying to pull the field names in the header of some JSON output. The following is a sample of the JSON header info: {"HEADER":{"company":{"label":"Company Name"},"streetaddress":{"label":"Street Address"},"ceo":{"label":"CEO Name","fields":{"firstname":{"label":"First Name"},"lastname":{"label":"Last Name"}}} I'm able to loop through the header and output the field and label (i.e. company and Company Name) using the following code: obj = JSON.parse(jsonResponse); for (var key in obj.HEADER) { response.write ( obj.HEADER[key].label ); response.write ( key ); } but can't figure out how to loop through and output the sub array of fields (i.e. firstname and First Name). Any ideas?

  • C++ assignment operators dynamic arrays

    - by user2905445
    First off i know the multiplying part is wrong but i have some questions about the code. 1. When i am overloading my operator+ i print out the matrix using cout << *this then right after i return *this and when i do a+b on matix a and matix b it doesnt give me the same thing this is very confusing. 2. When i make matrix c down in my main i cant use my default constructor for some reason because when i go to set it = using my assignment operator overloaded function it gives me an error saying "expression must be a modifiable value. although using my constructor that sets the row and column numbers is the same as my default constructor using (0,0). 3. My assignment operator= function uses a copy constructor to make a new matrix using the values on the right hand side of the equal sign and when i print out c it doesn't give me anything Any help would be great this is my hw for a algorithm class which i still need to do the algorithm for the multiplying matrices but i need to solve these issues first and im having a lot of trouble please help. //Programmer: Eric Oudin //Date: 10/21/2013 //Description: Working with matricies #include <iostream> using namespace std; class matrixType { public: friend ostream& operator<<(ostream&, const matrixType&); const matrixType& operator*(const matrixType&); matrixType& operator+(const matrixType&); matrixType& operator-(const matrixType&); const matrixType& operator=(const matrixType&); void fillMatrix(); matrixType(); matrixType(int, int); matrixType(const matrixType&); ~matrixType(); private: int **matrix; int rowSize; int columnSize; }; ostream& operator<< (ostream& osObject, const matrixType& matrix) { osObject << endl; for (int i=0;i<matrix.rowSize;i++) { for (int j=0;j<matrix.columnSize;j++) { osObject << matrix.matrix[i][j] <<", "; } osObject << endl; } return osObject; } const matrixType& matrixType::operator=(const matrixType& matrixRight) { matrixType temp(matrixRight); cout << temp; return temp; } const matrixType& matrixType::operator*(const matrixType& matrixRight) { matrixType temp(rowSize*matrixRight.columnSize, columnSize*matrixRight.rowSize); if(rowSize == matrixRight.columnSize) { for (int i=0;i<rowSize;i++) { for (int j=0;j<columnSize;j++) { temp.matrix[i][j] = matrix[i][j] * matrixRight.matrix[i][j]; } } } else { cout << "Cannot multiply matricies that have different size rows from the others columns." << endl; } return temp; } matrixType& matrixType::operator+(const matrixType& matrixRight) { if(rowSize == matrixRight.rowSize && columnSize == matrixRight.columnSize) { for (int i=0;i<rowSize;i++) { for (int j=0;j<columnSize;j++) { matrix[i][j] += matrixRight.matrix[i][j]; } } } else { cout << "Cannot add matricies that are different sizes." << endl; } cout << *this; return *this; } matrixType& matrixType::operator-(const matrixType& matrixRight) { matrixType temp(rowSize, columnSize); if(rowSize == matrixRight.rowSize && columnSize == matrixRight.columnSize) { for (int i=0;i<rowSize;i++) { for (int j=0;j<columnSize;j++) { matrix[i][j] -= matrixRight.matrix[i][j]; } } } else { cout << "Cannot subtract matricies that are different sizes." << endl; } return *this; } void matrixType::fillMatrix() { for (int i=0;i<rowSize;i++) { for (int j=0;j<columnSize;j++) { cout << "Enter the matix number at (" << i << "," << j << "):"; cin >> matrix[i][j]; } } } matrixType::matrixType() { rowSize=0; columnSize=0; matrix = new int*[rowSize]; for (int i=0; i < rowSize; i++) { matrix[i] = new int[columnSize]; } } matrixType::matrixType(int setRows, int setColumns) { rowSize=setRows; columnSize=setColumns; matrix = new int*[rowSize]; for (int i=0; i < rowSize; i++) { matrix[i] = new int[columnSize]; } } matrixType::matrixType(const matrixType& otherMatrix) { rowSize=otherMatrix.rowSize; columnSize=otherMatrix.columnSize; matrix = new int*[rowSize]; for (int i = 0; i < rowSize; i++) { for (int j = 0; j < columnSize; j++) { matrix[i]=new int[columnSize]; matrix[i][j]=otherMatrix.matrix[i][j]; } } } matrixType::~matrixType() { delete [] matrix; } int main() { matrixType a(2,2); matrixType b(2,2); matrixType c(0,0); cout << "fill matrix a:"<< endl;; a.fillMatrix(); cout << "fill matrix b:"<< endl;; b.fillMatrix(); cout << a; cout << b; c = a+b; cout <<"matrix a + matrix b =" << c; system("PAUSE"); return 0; }

  • Function pointer arrays in Fortran

    - by Eduardo Dobay
    I can create function pointers in Fortran 90, with code like real, external :: f and then use f as an argument to another function/subroutine. But what if I want an array of function pointers? In C I would just do double (*f[])(int); to create an array of functions returning double and taking an integer argument. I tried the most obvious, real, external, dimension(3) :: f but gfortran doesn't let me mix EXTERNAL and DIMENSION. Is there any way to do what I want? (The context for this is a program for solving a system of differential equations, so I could input the equations without having a million parameters in my subroutines.)

  • Reading a large file into Perl array of arrays and manipulating the output for different purposes

    - by Brian D.
    Hello, I am relatively new to Perl and have only used it for converting small files into different formats and feeding data between programs. Now, I need to step it up a little. I have a file of DNA data that is 5,905 lines long, with 32 fields per line. The fields are not delimited by anything and vary in length within the line, but each field is the same size on all 5905 lines. I need each line fed into a separate array from the file, and each field within the line stored as its own variable. I am having no problems storing one line, but I am having difficulties storing each line successively through the entire file. This is how I separate the first line of the full array into individual variables: my $SampleID = substr("@HorseArray", 0, 7); my $PopulationID = substr("@HorseArray", 9, 4); my $Allele1A = substr("@HorseArray", 14, 3); my $Allele1B = substr("@HorseArray", 17, 3); my $Allele2A = substr("@HorseArray", 21, 3); my $Allele2B = substr("@HorseArray", 24, 3); ...etc. My issues are: 1) I need to store each of the 5905 lines as a separate array. 2) I need to be able to reference each line based on the sample ID, or a group of lines based on population ID and sort them. I can sort and manipulate the data fine once it is defined in variables, I am just having trouble constructing a multidimensional array with each of these fields so I can reference each line at will. Any help or direction is much appreciated. I've poured over the Q&A sections on here, but have not found the answer to my questions yet. Thanks!! -Brian

  • Errors/warnings passing int/char arrays by reference

    - by Ankur Banerjee
    I'm working on a program where I try to pass parameters by reference. I'm trying to pass a 2D int array and a 1D char array by reference. Function prototype: void foo (int* (&a)[2][2], char* (&b)[4]) Function call: foo (a, b); However, when I compile the code with -ansi and -Wall flags on gcc, I get the following errors: foo.c: At top level: error: expected ‘)’ before ‘&’ token error: expected ‘;’, ‘,’ or ‘)’ before ‘char’ foo.c: In function ‘main’: error: too many arguments to function ‘foo’ I've stripped out the rest of the code of my program and concentrated on the bits which throw up the errors. I've searched around on StackOverflow and tried out different ways to pass the parameters, but none of them seem to work. (I took this way of passing parameters from the discussion on StackOverflow here.) Could you please tell me where I'm going wrong?

  • dynamically created arrays

    - by DevAno1
    My task consists of two parts. First I have to create globbal char array of 100 elements, and insert some text to it using cin. Afterwards calculate amount of chars, and create dedicated array with the length of the inputted text. I was thinking about following solution : char[100]inputData; int main() { cin >> inputData >> endl; int length=0; for(int i=0; i<100; i++) { while(inputData[i] == "\0") { ++count; } } char c = new char[count]; Am I thinking good ? Second part of the task is to introduce in the first program dynamically created array of pointers to all inserted words. Adding a new word should print all the previous words and if there is no space for next words, size of the inputData array should be increased twice. And to be honest this is a bit too much for me. How I can create pointers to words specifically ? And how can I increase the size of global array without loosing its content ? With some temporary array ?

  • foreach loop from multiple arrays c#

    - by Mike
    This should be a simple question. All I want to know is if there is a better way of coding this. I want to do a foreach loop for every array, without having to redeclare the foreach loop. Is there a way c# projects this? I was thinking of putting this in a Collection...? Please, critique my code. foreach (TextBox tb in vert) { if (tb.Text == box.Text) conflicts.Add(tb); } foreach (TextBox tb in hort) { if (tb.Text == box.Text) conflicts.Add(tb); } foreach (TextBox tb in cube) { if (tb.Text == box.Text) conflicts.Add(tb); }

  • Best practice for writing ARRAYS

    - by Douglas
    I've got an array with about 250 entries in it, each their own array of values. Each entry is a point on a map, and each array holds info for: name, another array for points this point can connect to, latitude, longitude, short for of name, a boolean, and another boolean The array has been written by another developer in my team, and he has written it as such: names[0]=new Array; names[0][0]="Campus Ice Centre"; names[0][1]= new Array(0,1,2); names[0][2]=43.95081811364498; names[0][3]=-78.89848709106445; names[0][4]="CIC"; names[0][5]=false; names[0][6]=false; names[1]=new Array; names[1][0]="Shagwell's"; names[1][1]= new Array(0,1); names[1][2]=43.95090307839151; names[1][3]=-78.89815986156464; names[1][4]="shg"; names[1][5]=false; names[1][6]=false; Where I would probably have personally written it like this: var names = [] names[0] = new Array("Campus Ice Centre", new Array[0,1,2], 43.95081811364498, -78.89848709106445, "CIC", false, false); names[1] = new Array("Shagwell's", new Array[0,1], 43.95090307839151, -78.89815986156464, 'shg", false, false); They both work perfectly fine of course, but what I'm wondering is: 1) does one take longer than the other to actually process? 2) am I incorrect in assuming there is a benefit to the compactness of my version of the same thing? I'm just a little worried about his 3000 lines of code versus my 3-400 to get the same result. Thanks in advance for any guidance.

  • static arrays defined with unspecified size, empty brackets?

    - by ahmadabdolkader
    For the C++ code fragment below: class Foo { int a[]; // no error }; int a[]; // error: storage size of 'a' isn't known void bar() { int a[]; // error: storage size of 'a' isn't known } why isn't the member variable causing an error too? and what is the meaning of this member variable? I'm using gcc version 3.4.5 (mingw-vista special) through CodeBlocks 8.02. On Visual Studio Express 2008 - Microsoft(R) C/C++ Optimizing Compiler 15.00.30729.01 for 80x86, I got the following messages: class Foo { int a[]; // warning C4200: nonstandard extension used : zero-sized array in struct/union - Cannot generate copy-ctor or copy-assignment operator when UDT contains a zero-sized array }; int a[]; void bar() { int a[]; // error C2133: 'a' : unknown size } Now, this needs some explaination too.

  • Jagged Edge Arrays in PHP

    - by chriscct7
    I want to store some data in (I guess a semi-2, semi-3d array) in PHP (5.3) What I need to do is store data about each floor like this: Floor Num of Spots Handicap Motorcyle Other 1 100 array(15,16,17) array (47,62) array (99,100) 2 100 array(15,16,17) array (47,62) array (99,100) and on The problem is, is if the Handicap+Motorcyle+Other were ints, I could just store the data in a 2d array. However, they aren't. So I was thinking I could make something almost like a 3D array, with the first two columns only being in 2D. The other thought I had was making a 2D array and for columns 3,4, and 5 instead of saving as array(15,16) //save like 1516 And then split at two digits (1 digit array numbers would be prefaced with a 0). However, I am wondering about the limit of the length of a string, because if I decide to move to a 3 digit length number in the array, like array(100, 104), and I need to store alot of numbers, I am thinking I am going to quickly exceed the max.

It is not elegant at all. Just wonder what is the better way to do it. Thanks!

  • HTML Calendar form and input arrays

    - by Christopher Ickes
    Hello. Looking for the best practice here... Have a form that consists of a calendar. Each day of the calendar has 2 text input fields - customer and check-in. What would be the best & most efficient way to send this form to PHP for processing? <form action="post"> <div class="day"> Day 1<br /> <label for="customer['.$current['date'].']">Customer</label> <input type="text" name="customer['.$current['date'].']" value="" size="20" /> <label for="check-in['.$current['date'].']">Check-In</label> <input type="text" name="check-in['.$current['date'].']" value="" size="20" /> <input type="submit" name="submit" value="Update" /> </day> <div class="day"> Day 2<br /> <label for="customer['.$current['date'].']">Customer</label> <input type="text" name="customer['.$current['date'].']" value="" size="20" /> <label for="check-in['.$current['date'].']">Check-In</label> <input type="text" name="check-in['.$current['date'].']" value="" size="20" /> <input type="submit" name="submit" value="Update" /> </day> </form> Is my current setup good? I feel there has to be a better option. My concern involves processing a whole year at once (which can happen) and adding additional text input fields.

  • 'Array of arrays' in matlab?

    - by waitinforatrain
    Hey, having a wee bit of trouble. Trying to assign a variable length 1d array to different values of an array, e.g. a(1) = [1, 0.13,0.52,0.3]; a(2) = [1, 0, .268]; However, I get the error: ??? In an assignment A(I) = B, the number of elements in B and I must be the same. Error in ==> lab2 at 15 a(1) = [1, 0.13,0.52,0.3]; I presume this means that it's expecting a scalar value instead of an array. Does anybody know how to assign the array to this value? I'd rather not define it directly as a 2d array as it is for are doing solutions to different problems in a loop Edit: Got it! a(1,1:4) = [1, 0.13,0.52,0.3]; a(2,1:3) = [1, 0, .268];
