  • javascript freezeing ie8

    - by florin
    Can someone tell me why does this code freeze ie8? It is supposed to generate input fields. In firefox, safari, chrome it works, but in in8 when i press generate button it freezes var monthNames = [ "Ianuarie", "Februarie", "Martie", "Aprilie", "Mai", "Iunie", "Iulie", "August", "Septembrie", "Octombrie", "Noiembrie", "Decembrie" ]; function buildMonthlyEntries() { var startDate = new Date(document.getElementById('datastart').value); var endDate = new Date(document.getElementById('dataend').value); if (startDate == "Invalid Date" || endDate == "Invalid Date") { return null; } var monthlyEntries = document.getElementById('monthlyEntries'); monthlyEntries.innerHTML = ""; // inclusiv dataend endDate.setMonth(endDate.getMonth() + 1); // start with startDate; loop until we reach endDate for (var dt = startDate; ! ( dt.getFullYear() == endDate.getFullYear() && dt.getMonth() == endDate.getMonth() ); dt.setMonth( dt.getMonth() + 1 ) ) { monthlyEntries.appendChild( document.createTextNode( monthNames[dt.getMonth()] + " " + String(dt.getFullYear()).substring(2) ) ); var textElement = document.createElement('input'); var textElement2 = document.createElement('input'); var textElement3 = document.createElement('input'); textElement.setAttribute('type', 'text'); //textElement.setAttribute('name', 'entry['+ monthNames[dt.getMonth()] + + String(dt.getFullYear()).substring(2) + ']'); textElement.setAttribute('name', 'entry[]'); textElement2.setAttribute('type', 'hidden'); textElement2.setAttribute('name', 'luna[]'); textElement2.setAttribute('value', '' + monthNames[dt.getMonth()] + ''); textElement3.setAttribute('type', 'hidden'); textElement3.setAttribute('name', 'an[]'); textElement3.setAttribute('value', '' + String(dt.getFullYear()) + ''); monthlyEntries.appendChild(textElement); monthlyEntries.appendChild(textElement2); monthlyEntries.appendChild(textElement3); // adauga br // monthlyEntries.appendChild(document.createElement("br")); } return null; }

  • SQL queries to determine all values that would satisfy an arbitrary query

    - by jasterm007
    I'm trying to figure out how to efficiently run a set of queries that will provide a new table of all values that would return results for an arbitrary query. Say my table has a schema like: id name age city What is an efficient way to list all values that would return results for an arbitrary query, say "NOT city=X AND age BETWEEN Y and Z"? My naive approach for this would be to use a script and recurse through all possible combinations of {city, age, age} and see which SELECTs return more than 0 results, but that seems incredibly inefficient. I've also tried building large joins on {city, age, age} as well and basically using that table as an argument list to the query, but that quickly becomes an impossibility for queries on many columns. For simple conjunctive equality queries, i.e. "name=X and age=Y", this is much simpler, as I can do something like SELECT name, age, count(*) AS count FROM main GROUP BY name, age HAVING count > 0 But I'm having difficulty coming up with a general approach for anything more complicated than that. Any pointers in the right direction would be most helpful, thanks.

  • manipulating radio box selection with javascript

    - by Crays
    Hi guys, i'm trying to do a poll but i designed it without any radio box in it. So i decided to make the selection being highlighted with a different background color, all is done with jquery. I set the display of the radio box to none so that it wouldn't show, gave each a unique ID. Here's the script. <form action="v_poll.php" method="post"> <ul class="voting"> <li class="voting votetext"><input type="radio" name="voting" value="a1" style="display:none;" id="a1"><a onClick="vote('a1')"Answer 1</a></li> <li class="voting votetext"><input type="radio" name="voting" value="a2" style="display:none;" id="a2"><a onClick="vote('a2')">Answer 2</a></li> <li class="voting votetext"><input type="radio" name="voting" value="a3" style="display:none;" id="a3"><a onClick="vote('a3')">Answer 3</a></li> <input type="hidden" value="1" name="id" /> <input type="submit" value="submit"> </ul> </form> <script type="text/javascript"> function vote(TheValue) { GetElementById(TheValue).checked=true; } </script> But when i checked the value of the radio box with $_POST['voting'], it is blank. Not the value assigned to the radio box. Anything i'm doing wrong? Please help. Thanks.

  • PHP dynamic Page-level DocBlocks

    - by Obmerk Kronen
    I was wondering if there is a way to interact with the Page-level DocBlocks. My question is more specifically about wordpress plugin development, but this question has arised also in a non-wordpress environments. The reason is mainly the possibility to easily change VERSIONS and names throughout a large project with maybe a constant definition - but that will reflect also in the docblock.. The following example Docblock is from a wordpress plugin I write - /* Plugin Name: o99 Auxilary Functions v0.4.7 Plugin URI: http://www.myurl.com Description: some simple description that nobody reads. Version: 0.4.7 Author: my cool name Author URI: http://www.ok-alsouri.com */ Is there a way to transform it into : $ver = '0.4.7'; $uri = 'http://www.myurl.com'; $desc = 'some simple description that nobody reads.'; $mcn = 'my cool name'; etc.. etc.. /* Plugin Name: o99 Auxilary Functions ($ver) Plugin URI: ($uri) Description: ($desc) Version: ($ver) Author: ($mcn) Author URI: ($$uri) */ obviously for echo to work I would need to break the docblock itself, and I can not WRITE the docblock directly into it´s own file . In shorts : can I "generate" a docblock with php itself somehow (I would think that the answer is - "no" for the page itself.. But maybe I am wrong and someone has some neat hack :-) ) Is that even possible ?

  • Variable wont echo

    - by jonnnnnnnnnie
    I have the following code, where the var $username doesn't echo, when you type in a value. //TODO: SET AUTH TOKEN as random hash, save in session $auth_token = rand(); if (isset($_POST['action']) && $_POST['action'] == 'Login') { $errors = array(); //USED TO BUILD UP ARRAY OF ERRORS WHICH ARE THEN ECHOED $username = $_POST['username']; if ($username = '') { $errors['username'] = 'Username is required'; } echo $username; // var_dump($username) returns string 0 } require_once 'login_form.html.php'; ?> login_form is this: <form method="POST" action=""> <input type="hidden" name="auth_token" value="<?php echo $auth_token ?>"> Username: <input type="text" name="username"> Password: <input type="password" name="password1"> <input type="submit" name="action" value="Login"> </form> The auth token part isn't important, it just when I type in a value in username textbox and press the login button, the username wont echo, var_dump returns string (0) and print_r is just blank.

  • $_POST Variable Detected in Chrome but not in Firefox

    - by user1707973
    I am using 2 images in a form to sort out query results from the database. The form is submitted using the POST method. When i click on the first image, the query results have to be sorted in ascending order, and when i click on the second, the results have to be sorted in the descending order. This is the code for the form: <form name="" action="" method="post"> <input type="hidden" name="typep" value="price" /> <input type="image" name="sort" value="asc" src="images/asc-ar.png" /> <input type="image" name="sort" value="desc" src="images/dsc-ar.png" /> </form> Now this is the code for checking if the $_REQUEST['sort'] variable is set and therefore whether sorting is required or not. if ($_REQUEST['sort'] != "") { $sort = $_REQUEST['sort']; $typep = $_REQUEST['typep']; //query to be executed depending on values of $sort and $typep } Firefox does detect the $_REQUEST['typep'] variable but not the $_REQUEST['sort'] one. This works perfectly in Chrome though. When i test the site in Firefox, it doesn't detect the $_REQUEST['sort'] variable and therefore the if condition evaluates to false and the search results don't get sorted.

    - by wibi
    Hi i am creating table using table helper, but in every row i want to add form, in html like this : <table> <form action=""> <tr> <td><input type="text" name="name2"></td> </tr> </form> <form action=""> <tr> <td><input type="text" name="name2"></td> </tr> </form> </table> But i want in table helper: I have tried this one: $this->table->add_row( form_open('myAction'). form_input('name'.$i), form_submit('Submit') form_close() ); And I use firebugs to inspect element produces, like this: <table> <tr> <form action="myAction"> <td><input type="text" name="name1"></td> </form> <td><input type="submit"></td> </tr> </table> why tag doesn't show at the last tag , but show at the first tag .

  • JavaScript two-dimensional Array to PHP

    - by vi
    Hi I have to send a two-dimensional JavaScript Array to a PHP page. Indeed, I'm working on a form-builder, in which the user can add or remove fields. These fields are added (or removed) using JavaScript (jQuery). When the user is done and hit a 'publish' button, I have to get all the fields concerned and send them to a PHP page which would build a real form with it. I found a way to do it but I'm pretty sure it's not very clean : addedFields = new Array(); $("#add-info .field").each(function() { addedFields.push(new Array($(this).find('.name').val(), $(this).find('.type').val(), $(this).find('.size').val())); }); Basically, the ".field" class objects are <tr> and the ".name", ".type" and ".size" objects are inputs. So I get an array of [name, type, size], then I convert it into a string using addedFields = addedFields.join(";"); Finally, I go to the PHP form that way ; document.location.href = "create.php?addedfields=" + addedFields; Concerning the PHP code, I create a PHP array using the explode() function: $addedFields = explode(";", $_GET['addedfields']); and then I use it again for each element in the array: foreach ($addedFields as $field) { $field = explode(",", $field); echo "<li>Field with name : '$field[0]', of '$field[1]' type and with a size of $field[2]"; }

  • Why my oracleParameter doesnt work?

    - by user1824356
    I'm a .NET developer and this is the first time i work with oracle provider (Oracle 10g and Framework 4.0). When i add parameter to my command in this way: objCommand.Parameters.Add("pc_cod_id", OracleType.VarChar, 4000).Value = codId; objCommand.Parameters.Add("pc_num_id", OracleType.VarChar, 4000).Value = numId; objCommand.Parameters.Add("return_value", OracleType.Number).Direction = ParameterDirection.ReturnValue; objCommand.Parameters.Add("pc_email", OracleType.VarChar, 4000).Direction = ParameterDirection.Output; I have no problem with the result. But when a add parameter in this way: objCommand.Parameters.Add(CreateParameter(PC_COD_ID, OracleType.VarChar, codId, ParameterDirection.Input)); objCommand.Parameters.Add(CreateParameter(PC_NUM_ID, OracleType.VarChar, numId, ParameterDirection.Input)); objCommand.Parameters.Add(CreateParameter(RETURN_VALUE, OracleType.Number, ParameterDirection.ReturnValue)); objCommand.Parameters.Add(CreateParameter(PC_EMAIL, OracleType.VarChar, ParameterDirection.Output)); The implementation of that function is: protected OracleParameter CreateParameter(string name, OracleType type, ParameterDirection direction) { OracleParameter objParametro = new OracleParameter(name, type); objParametro.Direction = direction; if (type== OracleType.VarChar) { objParametro.Size = 4000; } return objParametro; } All my result are a empty string. My question is, these way to add parameters are not the same? And if no, what is the difference? Thanks :) Add: Sorry i forgot mention "CreateParameter" is a function with multiple implementations the base is the above function, the other use that. protected OracleParameter CreateParameter(string name, OracleType type, object value, ParameterDirection direction) { OracleParameter objParametro = CreateParameter(name, type, value); objParametro.Direction = direction; return objParametro; } The last parameters doesn't need value because those are output parameter, those bring me data from the database.

  • Linq2Sql - attempting to update but the Set statement in sql is empty

    - by MrTortoise
    This is weird ... done updates loads of times before but cannot spot why this is different. I have a client class from the dbml I added a method called update public void UpdateSingle() { L2SDataContext dc = new L2SDataContext(); Client c = dc.Clients.Single<Client>(p => p.ID == this.ID); c.CopyToMe(this); c.updatedOn = DateTime.Now; dc.SubmitChanges(); dc.Dispose(); } The CopytoMe method public void CopyToMe(Client theObject) { if (ID != theObject.ID) { ID = theObject.ID; } /// this is redundant as generated code checks field for a change. deleted = theObject.deleted; deletedBy = theObject.deletedBy; deletedOn = theObject.deletedOn; insertedBy = theObject.insertedBy; insertedOn = theObject.insertedOn; name = theObject.name; updatedBy = theObject.updatedBy; updatedOn = theObject.updatedOn; } Im taking a client that was selected, changing its name and then calling this update method. The generated sql is as follows exec sp_executesql N'UPDATE [dbo].[tblClient] SET WHERE ([ID] = @p0) AND ([name] = @p1) AND ([insertedOn] = @p2) AND ([insertedBy] = @p3) AND ([updatedOn] = @p4) AND ([updatedBy] = @p5) AND ([deletedOn] IS NULL) AND ([deletedBy] IS NULL) AND (NOT ([deleted] = 1))',N'@p0 int,@p1 varchar(8000),@p2 datetime,@p3 int,@p4 datetime,@p5 int',@p0=103,@p1='UnitTestClient',@p2=''2010-05-17 11:33:22:520'',@p3=3,@p4=''2010-05-17 11:33:22:520'',@p5=3 I have no idea why this is not working ... used this kind of select object, set field to new value submit the selected object pattern many times and not had this problem. there is also nothing obviously wrong with the dbml - although this is probably a false statement any ideas?

  • Destroy? Delete? What's going on here? Rails 2.3.5

    - by Steve
    I am new to rails. My rails version is 2.3.5. I found usage like: In controller, a destroy method is defined and in view, you can use :action = "delete" to fire that method. Isn't the action name has to be the same as the method name? Why delete is mapped to destroy? Again, in my controller, I define a method called destroy to delete a record. In a view, I have <%= link_to "remove", :action = 'destroy', :id = myrecord %. But it never works in practice. Every time I press the remove link, it redirects me to the show view, showing the record's content. I am pretty sure that my destroy method is: def destroy @myobject = MyObject.find(params[:id]) @myobject.destroy @redirect_to :action = 'index' end If I change the method name from destroy to something like remove_me and change the action name to remove_me in the view, everything works as expected. In the above two wired problems, I am sure there is no tricky rountting set in my configuration. All in all, seems the destroy and delete are mysterious keywords in rails. Anyone can explain this to me? Thank you very much.

  • jQuery - Cancel form submit (using "return false"?)?

    - by Nike
    Hey there. I'm running into a bit of trouble while trying to cancel the submit of a form. I've been following this tutorial (even though i'm not making a login script), and it seems to be working for him. Here's my form: <form action="index.php" method="post" name="pForm"> <textarea name="comment" onclick="if(this.value == 'skriv här...') this.value='';" onblur="if(this.value.length == 0) this.value='skriv här...';">skriv här...</textarea> <input class="submit" type="submit" value="Publicera!" name="submit" /> </form> And here's the jquery: $(document).ready(function() { $('form[name=pForm]').submit(function(){ return false; }); }); I've already imported jQuery in the header and i know it's working. My first thought was that it might be outdated, but it's actually "just" a year ago. So do anyone see what's wrong? Thanks in advance. EDIT: From what i've read the easiest and most appropriate way to abort the submit is to return false? But i can't seem to get it working. I've searched the forum and i've found several helpful threads but none of them actually works. I must be screwing something up.

  • Expressjs route param as variable in main app

    - by MoDFoX
    For my app I have two route set up, app.get('/', routes.index); app.get('/:name', routes.index); I would like it to be so that if I don't specify a param, say just go to appurl.com (localhost:3000), it would load a default user, but if I do specify a param(localhost:3000/user), use that as the variable "username" in the following function (placed after my routes). (function getUser(){ var body = '', username = 'WillsonSM', options = { host: 'ws.audioscrobbler.com', port: 80, path: '/2.0/?method=user.gettopartists&user=' + username + '&format=json&limit=20&api_key=APIKEYGOESHERE' }; require('http').request(options, function(res) { res.setEncoding('utf8'); res.on('data', function(chunk) { body += chunk; }); res.on('end', function() { body = JSON.parse(body); artists = body.topartists.artist; }); }).end(); })(); Along with this I have my route set up like so: exports.index = function(req, res){ res.render('index', { title: 'LasTube' }); username = req.params.name; console.log(username); }; unfortunately setting username there to req.params.name does not seem to be accessible from the main app function. My question is: How can I set expressjs/nodejs to use the parameter set via /name when available, and just use a default - in this example "WillsonSM" if not available. I've tried taking "username" out of the main app, and just leaving it in the function, but username becomes undefined, as it is inaccessible from the route, and the app will not run. I can spit out "username" via the routes console.log, so assigning it there is not an issue, but as I am new to expressjs, I am unaware of how I should go about doing this. I have tried all I can think of and find from looking around the internet. Also, if there is a better way of doing this, or I am doing something wrong, please let me know. If I've left out any information, just throw in a comment and I'll try to address it.

  • EventHandlers saved to databases.

    - by Stacey
    In a database application (using Sql Server right now, in C#, with Entity Framework 4.0) I have a situation where I need to trigger events when some values change. For instance assume a class "Trackable". class Trackable { string Name { get; set; } int Positive { get; set; } int Negative { get; set; } int Total { get; set; } // event OnChanged } Trackable is represented in the database as follows; table Trackables Id | guid name | varchar(32) positive | int negative | int Total is of course, calculated at runtime. When a trackable event changes, I want to inspect its previous value, and then see what it is changing to, and be capable of reacting accordingly. However different trackables need to trigger different events (to avoid a huge, massive cascading switch/if block). If this were just only C# code it would be easy - but they have to be saved to the database. I can't divide up each different trackable into a different table/class, that would be silly - they are all identical, but the event raised is different based on how they are made. So I guess my question is, is there any way to store an event handler in a database such that.. Trackable t1 = new Trackable() { Name = "Trackable1" OnChange += TrackableChangedEventHandler(OnTrackable1Change) } Trackable t2 = new Trackable() { Name = "Trackable2", OnChange += TrackableChangedEventHandler(OnTrackable2Change) }

  • What's a good way to integrate FB and Twitter into my commenting system (PHP)

    - by Jason
    Hi Guys, There are so many options out there for integration. At the moment I have comments that are posted on my articles, where a user types in their name and the comment. This is then sent to a moderation queue and displayed when approved. I want to acheive this: Comment with facebook login (ie facebook account listed as the name w/ avatar) Comment with twitter login (ie twitter account name listed as the name w/ avatar) Push comment from my website to twitter and to facebook I could go down a few paths as far as I know: Integrate with XFBML, which I don't like because I find it annoying to setup and messy. Integrate facebook comments system, although this can't push to twitter, or allow me to moderate comments from my backend (as far as I can tell i'd have to login under the facebook login for the dev account to moderate the comment) Find a php class that does open auth and integrate with both face book and twitter at once find a pre-created php class Anyone have a solution that will bias: a. easy to integrate b. lightweight c. is free Thanks for your suggestions in advance.

  • how to get something to display only once in a while loop

    - by Matt Nathanson
    I've got a mysql query running and it checks to see if an iterator is equal to 1, then display this div title... if ($this->dliterator == 1) {echo "<div class='clientsection' id='downloads'>Downloads</div><br/>";}; The problem is, is that the dl iterator may not necessarily start at 1. (it is directly related to a downloadid from the database). How can I get this to display only for the first time through the loop ONLY? while ($row = mysql_fetch_assoc($result)) { if ($row['download'] != null){ if ($this->dliterator == 1) {echo "<div class='clientsection' id='downloads'>Downloads</div><br/>";}; if ($editDownload == 1) { echo "<div class='clientlink' style='margin-top: 15px;'>"; echo "<input name='downloads[$this->dliterator][name]' type='text' id='download$this->dliterator' value='" . $row['download'] .

  • NSPredicate (Core Data fetch) to filter on an attribute value being present in a supplied set (list)

    - by starbaseweb
    I'm trying to create a fetch predicate that is the analog to the SQL "IN" statement, and the syntax to do so with NSPredicate escapes me. Here's what I have so far (the relevant excerpt from my fetching routine): NSFetchRequest *request = [[[NSFetchRequest alloc] init] autorelease]; NSEntityDescription *entity = [NSEntityDescription entityForName: @"BodyPartCategory" inManagedObjectContext:_context]; [request setEntity:entity]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"(name IN %@)", [RPBodyPartCategory defaultBodyPartCategoryNames]]; [request setPredicate:predicate]; The entity "BodyPartCategory" has a string attribute "name". I have a list of names (just NSString objects) in an NSArray as returned by: [RPBodyPartCategory defaultBodyPartCategoryNames] So let's say that array has string such as {@"Liver", @"Kidney", @"Thyroid"} ... etc. I want to fetch all 'BodyPartCategory' instances whose name attribute matches one of the strings in the set provided (technically NSArray but I can make it an NSSet). In SQL, this would be something like: SELECT * FROM BodyPartCategories WHERE name IN ('Liver', 'Kidney', 'Thyroid') I've gone through various portions of the Predicate Programming Guide, but I don't see this simple use case covered. Pointers/help much appreciated!

  • Minimizing MySQL output with Compress() and by concatening results?

    - by johnrl
    Hi all. It is crucial that I transfer the least amount of data possible between server and client. Therefore I thought of using the mysql Compress() function. To get the max compression I also want to concatenate all my results in one large string (or several of max length allowed by MySql), to allow for similar results to be compressed, and then compress these/that string. 1st problem (concatenating mysql results): SELECT name,age FROM users returns 10 results. I want to concatenate all these results in one strign on the form: name,age,name,age,name,age... and so on. Is this possible? 2nd problem (compressing the results from above) When I have comstructed the concatenated string as above I want to compress it. If I do: SELECT COMPRESS('myname'); then it just gives me as output the character '-' - sometimes it even returns unprintable characters. How do I get COMPRESS() to return a compressed printable string that I can trasnfer in ex ASCII encoding?

We met on Monday and just went over the syllabus, and on Wednesday the network at school was down so we couldn't even do the power point lecture. Right now I am working on my first homework assignment and I am almost finished but I am having trouble on one question. Here is is... Write a SELECT statement that returns one column from the Customers table named FullName that joins the LastName and FirstName columns. Format the columns with the last name, a comma, a space, and the first name like this: Doe, John Sort the result set by last name in ascending sequence. Return only the contacts whose last name begins with letters from M to Z. Here is what I have so far... USE md0577283 SELECT FirstName,LastName FROM Customers ORDER BY LastName,FirstName My question is how do I format is Lastname, FirstName like the professor wants and how do I only select names M-Z? If someone could point me in the right direction I would greatly appreciate it. Thank you. PS With all do respect, I didn't ask for the answer I asked for a nudge in the right direction so why the down vote guys?

  • Python: Trouble with YACC

    - by Rosarch
    I'm parsing sentences like: "CS 2310 or equivalent experience" The desired output: [[("CS", 2310)], ["equivalent experience"]] YACC tokenizer symbols: tokens = [ 'DEPT_CODE', 'COURSE_NUMBER', 'OR_CONJ', 'MISC_TEXT', ] t_DEPT_CODE = r'[A-Z]{2,}' t_COURSE_NUMBER = r'[0-9]{4}' t_OR_CONJ = r'or' t_ignore = ' \t' terms = {'DEPT_CODE': t_DEPT_CODE, 'COURSE_NUMBER': t_COURSE_NUMBER, 'OR_CONJ': t_OR_CONJ} for name, regex in terms.items(): terms[name] = "^%s$" % regex def t_MISC_TEXT(t): r'\S+' for name, regex in terms.items(): # print "trying to match %s with regex %s" % (t.value, regex) if re.match(regex, t.value): t.type = name return t return t (MISC_TEXT is meant to match anything not caught by the other terms.) Some relevant rules from the parser: precedence = ( ('left', 'MISC_TEXT'), ) def p_statement_course_data(p): 'statement : course_data' p[0] = p[1] def p_course_data(p): 'course_data : course' p[0] = p[1] def p_course(p): 'course : DEPT_CODE COURSE_NUMBER' p[0] = make_course(p[1], int(p[2])) def p_or_phrase(p): 'or_phrase : statement OR_CONJ statement' p[0] = [[p[1]], [p[3]]] def p_misc_text(p): '''text_aggregate : MISC_TEXT MISC_TEXT | MISC_TEXT text_aggregate | text_aggregate MISC_TEXT ''' p[0] = "%s %s" % (p[0], [1]) def p_text_aggregate_statement(p): 'statement : text_aggregate' p[0] = p[1] Unfortunately, this fails: # works as it should >>> token_list("CS 2110 or equivalent experience") [LexToken(DEPT_CODE,'CS',1,0), LexToken(COURSE_NUMBER,'2110',1,3), LexToken(OR_CONJ,'or',1,8), LexToken(MISC_TEXT,'equivalent',1,11), LexToken(MISC_TEXT,'experience',1,22)] # fails. bummer. >>> parser.parse("CS 2110 or equivalent experience") Syntax error in input: LexToken(MISC_TEXT,'equivalent',1,11) What am I doing wrong? I don't fully understand how to set precedence rules. Also, this is my error function: def p_error(p): print "Syntax error in input: %s" % p Is there a way to see which rule the parser was trying when it failed? Or some other way to make the parser print which rules its trying?

  • problem using fprintf

    - by shiran bar
    I'm trying to print to a text file numerous variables yet it doesn't work. I checked and verified that i write it in the correct syntax. I also checked the return value and it's positive therefore i know it did write to the file, however when i open the file it's empty. I would be happy for some help. This is the code: I initiate DynsaleDayPtr in the main: FILE* DynsaleDayPtr = CreateTextFiles("sale_day.txt"); Create function: FILE* CreateTextFiles (char* fileName) { FILE* saleFilePtr=NULL; if((saleFilePtr=fopen(fileName,"a+"))==NULL) printf("File couldn't be opened\n"); return saleFilePtr; } The call to the function TextAddSale is done from a function that is called in the main: TextAddSale(DynSaleDayPtr,dynNumOfRecords); Bool TextAddSale (FILE* DynsaleDayPtr, int* dynNumOfRecords) { char id[6]; char name [50]; char priceChar[20]; char* tmp = NULL; int price=-1; DynamicRecord * newRec=NULL; scanf("%s%s%s",id,name,priceChar); newRec = (DynamicRecord *)malloc(sizeof(DynamicRecord)); if (newRec == NULL) return False; tmp = (char*)malloc(strlen(name)+1); if (tmp == NULL) { free (newRec); return False; } strcpy(tmp,name); newRec->productName = tmp; strcpy(newRec->productId, id); newRec->productPrice=atoi (priceChar); if (fprintf(DynsaleDayPtr,"%d %s %s %d", strlen(newRec->productName), newRec->productId, newRec->productName, newRec->productPrice)>0) { *dynNumOfRecords=(*dynNumOfRecords)+1; return True; } } thanks!
