  • Can you restrict the location of input type=file?

    - by dcp3450
    Is there a way to restrict the user to a folder on the server when they choose to browse for a file using the input type=file button? for example: If you have images you want the user to choose from that only exist in the server's image folder to prevent them from search for and uploading their own images.

  • Should the function or the caller be resonsible for input validation?

    - by haudenschilt
    I'm doing a security audit on a fairly large php application and was wondering where I should include my user-input validation. Should I validate the data, then send the clean data off to the back-end functions or should I rely on each function to do it's own validation? Or even both? Is there any standard or best-practice for this sort of thing? Currently the app does both inconsistently and I'll like to make things more consistent.

  • function using cl-who:with-html-output ignoring parameter

    - by shanked
    I'm not sure whether this is an issue with my use of cl-who (specifically with-html-output-to-string and with-html-output) or an issue with my understanding of Common Lisp (as this is my first project using Lisp). I created a function to create form fields: (defun form-field (type name label) (cl-who:with-html-output (*standard-output* nil) (:div :class "field" (:label :for name label) (:input :type type :name name)))) When using this function, ie: (form-field "text" "username" "Username") the parameter label seems to be ignored... the HTML output is: <div class="field"><label for="username"></label> <input type="text" name="username"/></div> instead of the expected output: <div class="field"><label for="username">Username</label> <input type="text" name="username"/></div> If I modify the function and add a print statement: (defun form-field (type name label) (cl-who:with-html-output (*standard-output* nil) (print label) (:div :class "field" (:label :for name label) (:input :type type :name name)))) The "Username" string is successfully output (but still ignored in the HTML)... any ideas what might cause this? Keep in mind, I'm calling this function within a cl-who:with-html-output-to-string for use with hunchentoot.

  • How can I use scp without providing a password

    - by Tim
    I have asked a question before in here. My question was that I tried to give my password to scp via piping echo mypassword | scp [email protected]:project/* ~/project/ However it still asks me to manually input the password. How should I specify mypassword to scp in commands? I still don't understand one of the replies. what is a input stream by TTY, for example? What are the common ways for a input stream? How to know what type of input stream a stdin input to a command is? For example that of ssh/scp.

  • Is there a way to make PHP progressively output as the script executes?

    - by Iain Fraser
    So I'm writing a disposable script for my own personal single use and I want to be able see how the process is going. Basically I'm processing a couple of thousand media releases and sending them to our new CMS. So I don't hammer the CMS, I'm making the script sleep for a couple of seconds after every 5 requests. I would like - as the script is executing - to be able to see my echos telling me the script is going to sleep or that the last transaction with the webservice was successful. Is this possible in PHP? Thanks for your help! Iain

    - by metaculus
    This is how it is supposed to look like on Airbnb home page http://airbnb.com I have tried .input-group-addon and nest in it another <input> like so: <div class="col-lg-6"> <div class="input-group"> <input type="text" class="form-control"> <span class="input-group-addon"> <input type="text" id="nested-input" class="form-control"> </span> <span class="input-group-btn"> <button class="btn btn-default" type="button">Go!</button> </span> </div> </div> </div> And it didn't work. Does Bootstrap support this styling?

  • jQuery .val Enigma between two input boxes

    - by Matt
    I'm trying to get it so that if I move a red div-square around the screen using jQuery UI and jQuery, then an input field updates with the position of the div. I got that working with a simple .val. But, it's hard to explain why, but I need to make it so that when I move the square, it updates my input box, and when the input box value is changed, another input box reflects the new value of the old input box. Do I make any sense, coz I'm confusing myself :). I made a jsfiddle, so perhaps it'll make more sense there. If you move the red square, then the input box directly above it updates, but the input box above that does not, even though it is programmed to reflect the value of the input box below itself. P.S. Is this specific to only jQuery, or is this problem present in all of JavaScript. Thanks! http://jsfiddle.net/xmCsq/27/

  • Compare output of program to correct program using bash script, without using text files

    - by Doug
    I've been trying to compare the output of a program to known correct output by using a bash script without piping the output of the program to a file and then using diff on the output file and a correct output file. I've tried setting the variables to the output and correct output and I believe it's been successful but I can't get the string comparison to work correctly. I may be wrong about the variable setting so it could be that. What I've been writing: TEST=`./convert testdata.txt < somesampledata.txt` CORRECT="some correct output" if [ "$TEST"!="$CORRECT" ]; then echo "failed" fi

  • what is a fast way to output h5py dataset to text?

    - by user362761
    I am using the h5py python package to read files in HDF5 format. (e.g. somefile.h5) I would like to write the contents of a dataset to a text file. For example, I would like to create a text file with the following contents: 1,20,31,75,142,324,78,12,3,90,8,21,1 I am able to access the dataset in python using this code: import h5py f = h5py.File('/Users/Me/Desktop/thefile.h5', 'r') group = f['/level1/level2/level3'] dset = group['dsetname'] My naive approach is too slow, because my dataset has over 20000 entries: # write all values to file for index in range(len(dset)): # do not add comma after last value if index == len(dset)-1: txtfile.write(repr(dset[index])) else: txtfile.write(repr(dset[index])+',') txtfile.close() return None Is there a faster way to write this to a file? Perhaps I could convert the dataset into a NumPy array or even a Python list, and then use some file-writing tool? (I could experiment with concatenating the values into a larger string before writing to file, but I'm hoping there's something entirely more elegant)

  • How to column-ify an output from a certain program?

    - by mbaitoff
    I have a program that generates and outputs a sequence of simple sample math homework tasks, like: 1 + 1 = ... 3 + 3 = ... 2 + 5 = ... 3 + 7 = ... 4 + 2 = ... a sequence can be quite long, and I'd like to save space when this sequence is printed by converting it as follows: 1 + 1 = ... 3 + 7 = ... 3 + 3 = ... 4 + 2 = ... 2 + 5 = ... that is, wrapping the lines into the two or more columns. I was expecting the column linux utility to do the job using the -c N option witn N=2, however, it still outputs the lines in one column whatever the N is. How would I do the column-ifying of the sequence of lines?

  • HTML - Styling a input type=submit as an anchor and removing extra space rendered

    - by Malcolm
    Hi, I have the following HTML and you can see the extra space between the links when the page renders. How do trim this space? <div class="navLinks" style="text-align:right;margin-bottom:30px;"> <form action="/Invoice/SetPaid" method="post"><input id="id" name="id" type="hidden" value="11356" /> <input type="submit" value="Set To Paid" /> </form><form action="/Invoice/WorkInProgress" method="post"><input id="id" name="id" type="hidden" value="11356" /> <input type="submit" value="Set To Work In Progress" /> </form><form action="/Invoice/PrintVersion/11356" method="post"><input id="id" name="id" type="hidden" value="11356" /> <input type="submit" value="Printable Version" /> </form><form action="/Home/User" method="post"><input id="id" name="id" type="hidden" value="11356" /> <input type="submit" value="Continue" /> </form> </div> .navLinks form { display:inline; } .navLinks input { text-decoration:underline; background-color:white; color: #034af3; border: 0px none; text-align:center; } .navLinks input:hover { text-decoration:none; }

  • How to style just one type of input field without also affecting other input types with CSS

    - by James
    Is there a way to write style rules that will only influence text fields. Suppose I have the following: <div id="helloDiv"> <input type="text" name="something" /><br /> <input type="checkbox" name="somethingElse" /><br /> <input type="submit" name="go" /> </div> div#helloDiv input { border: 1px solid red; } The problem with the above CSS rule is that it will affect ALL input fields not just input text but also radio buttons, submit buttons, etc. So is there a cross browser solution to affect just one type of input field within a div or other page element (without resorting to assigning the input fields styles individually).

  • Selecting the correct input field using jquery

    - by rshivers
    I'm trying to select the id's of dynamic input fields in my code. When clicking a button, the form will create a form field like this: <td><input type="text" id="field_a_1"></td> <td><input type="text" id="field_b_1"></td> <td><input type="text" id="field_c_1"></td> When I click on the button again I get this: <td><input type="text" id="field_a_2"></td> <td><input type="text" id="field_b_2"></td> <td><input type="text" id="field_c_2"></td> What I want to do is select only the field id that I need to pull the value from that particular input and pass it to a variable like this: var example = $(":input:eq(0)").val(); I know that by adding the :eq(0) after the :input selector it will only grab the id for field_a_1, so how do I set it up so that I can pull just the field that I need to assign it to a variable?

  • How can I merge the different keyboard indicators?

    - by Agmenor
    Presently I use two application indicators showing a keyboard: input methods (iBus) keyboard layout Is there a way to make them merge into one single indicator icon ? What I have in mind is the equivalent of the messaging menu (gathering all that is related to communications) or the sound menu (gathering all the controls for sound). If it is too complicated to merge the indicators, is the merge planned for an upcoming Ubuntu release? I am on Ubuntu 11.10 with Unity as my environment.

  • Making user input/math on data fast, unlike excel type programs

    - by proGrammar
    I'm creating a research platform solely for myself to do some research on data. Programs like excel are terribly slow for me so I'm trying to come up with another solution. Originally I used excel. A1 was the cell that contained the data and all other cells in use calculated something on A1, or on other cells, that all could be in the end traced to A1. A1 was like an element of an array, I then I incremented it to go through all my data. This was way too slow. So the only other option I found originally was to hand code in c# the calculations inside a loop. Then I simply recompiled each time I changed my math. This was terribly slow to do and I had to order everything correctly so things would update correctly (dependencies). I could have also used events, but hand coding events for each cell like calculation would also be very slow. Next I created an application to read Excel and to perfectly imitate it. Which is what I now use. Basically I write formulas onto a fraction of my data to get live results inside excel. Then my program reads excel, writes another c# program, compiles it, and runs that program which runs my excel created formulas through a lot more data a whole lot faster. The advantage being my application dependency sorts everything (or I could use events) so I don't have to (like excel does) And of course the speed. But now its not a single application anymore. Instead its 2 applications, one which only reads my formulas and writes another program. The other one being the result which only lives for a short while before I do other runs through my data with different formulas / settings. So I can't see multiple results at one time without introducing even more programs like a database or at least having the 2 applications talking to each other. My idea was to have a dll that would be written, compiled, loaded, and unloaded again and again. So a self-updating program, sort of. But apparently that's not possible without another appdomain which means data has to be marshaled to be moved between the appdomains. Which would slow things down, not for summaries, but for other stuff I need to do with all my data. I'm also forgetting to mention a huge problem with restarting an application again and again which is having to reload ALL my data into memory again and again. But its still a whole lot faster than excel. I'm really super puzzled as to what people do when they want to research data fast. I'm completely unable to have a program accept user input and having it fast. My understanding is that it would have to do things like excel which is to evaluate strings again and again. So my only option is to repeatedly compile applications. Do I have a correct understanding on computer science? I've only just began programming, and didn't think I would have to learn much to do some simple math on data. My understanding is its either compiling my user defined stuff to a program or evaluating them from a string or something stupid again and again. And my only option is to probably switch operating systems or something to be able to have a program compile and run itself without stopping (writing/compiling dll, loading dll to program, unloading, and repeating). Can someone give me some idea on how computers work? Is anything better possible? Like a running program, that can accept user input and compile it and then unload it later? I mean heck operating systems dont need to be RESTARTED with every change to user input. What is this the cave man days? Sorry, it's just so super frustrating not knowing what one can do, and can't do. If only I could understand and learn this stuff fast enough.

  • Output Audio via HDMI and Analog Out Simultaneously

    - by Alex Miller
    I need to output the system audio from a desktop to both the HDMI output (sending to the display that functions as the room speakers) and via the analog stereo output (to feed the reference input on a microphone array for Skype). The only solution I've found so far for this is an HDMI Audio De-Embedder, but I'd really like to avoid buying another piece of hardware, so I'm hoping there's a way to do this inside software. So: Is there any way to make Windows 7 output all audio over both HDMI and Analog outs, simultaneously?
