6,846,405 | 0 | CSV file generation error <p>I'm working on a project for a client - a wordpress plugin that creates and maintains a database of organization members. I'll note that this plugin creates a new table within the wordpress database (instead of dealing with the data as custom_post_type meta data). I've made a lot of modifications to much of the plugin, but I'm having an issue with a feature (that I've left unchanged).</p> <p>One half of this feature does a csv import and insert, and that works great. The other half of this sequence is a feature to download the contents of this table as a csv. This part works fine on my local system, but fails when running from the server. I've poured over each portion of this script and everything seems to make sense. I'm, frankly, at a loss as to why it's failing.</p> <p>The php file that contains the logic is simply linked to. The file:</p> <pre><code><?php // initiate wordpress include('../../../wp-blog-header.php'); // phpinfo(); function fputcsv4($fh, $arr) { $csv = ""; while (list($key, $val) = each($arr)) { $val = str_replace('"', '""', $val); $csv .= '"'.$val.'",'; } $csv = substr($csv, 0, -1); $csv .= "\n"; if (!@fwrite($fh, $csv)) return FALSE; } //get member info and column data $table_name = $wpdb->prefix . "member_db"; $year = date ('Y'); $members = $wpdb->get_results("SELECT * FROM ".$table_name, ARRAY_A); $columns = $wpdb->get_results("SHOW COLUMNS FROM ".$table_name, ARRAY_A); // echo 'SQL: '.$sql.', RESULT: '.$result.'<br>'; //output headers header("Content-type: application/octet-stream"); header("Content-Disposition: attachment; filename=\"members.csv\""); //open output stream $output = fopen("php://output",'w'); //output column headings $data[0] = "ID"; $i = 1; foreach ($columns as $column){ //DIAG: echo '<pre>'; print_r($column); echo '</pre>'; $field_name = ''; $words = explode("_", $column['Field']); foreach ($words as $word) $field_name .= $word.' '; if ( $column['Field'] != 'id' && $column['Field'] != 'date_updated' ) { $data[$i] = ucwords($field_name); $i++; } } $data[$i] = "Date Updated"; fputcsv4($output, $data); //output data foreach ($members as $member){ // echo '<pre>'; print_r($member); echo '</pre>'; $data[0] = $member['id']; $i = 1; foreach ($columns as $column){ //DIAG: echo '<pre>'; print_r($column); echo '</pre>'; if ( $column['Field'] != 'id' && $column['Field'] != 'date_updated' ) { $data[$i] = $member[$column['Field']]; $i++; } } $data[$i] = $member['date_updated']; //echo '<pre>'; print_r($data); echo '</pre>'; fputcsv4($output, $data); } fclose($output); ?> </code></pre> <p>So, obviously, a routine wherein a query is run, <code>$output</code> is established with <code>fopen</code>, each row is then formatted as comma delimited and <code>fwrite</code>d, and finally the file is <code>fclose</code>d where it gets pushed to a local system.</p> <p>The error that I'm getting (from the server) is </p> <pre><code>Error 6 (net::ERR_FILE_NOT_FOUND): The file or directory could not be found. </code></pre> <p>But it clearly is getting found, its just failing. If I enable <code>phpinfo()</code> (PHP Version 5.2.17) at the top of the file, I definitely get a response - notably <code>Cannot modify header information</code> (I'm pretty sure because <code>phpinfo()</code> has already generated a header). All the expected data does get printed to the bottom of the page (after all the phpinfo diagnostics), however, so that much at least is working correctly.</p> <p>I am guessing there is something preventing the <code>fopen</code>, <code>fwrite</code>, or <code>fclose</code> functions from working properly (a server setting?), but I don't have enough experience with this to identify exactly what the problem is. </p> <p>I'll note again that this works exactly as expected in my test environment (localhost/XAMPP, netbeans).</p> <p>Any thoughts would be most appreciated. </p> <h3>update</h3> <p>Ok - spent some more time with this today. I've tried each of the suggested fixes, including @Rudu's <code>writeCSVLine</code> fix and @Fernando Costa's <code>file_put_contents()</code> recommendation. The fact is, they all work locally. Either just <code>echo</code>ing or the <code>fopen</code>,<code>fwrite</code>,<code>fclose</code> routine, doesn't matter, works great. </p> <p>What does seem to be a problem is the inclusion of the <code>wp-blog-header.php</code> at the start of the file and then the additional <code>header()</code> calls. (The path is definitely correct on the server, btw.)</p> <p>If I comment out the <code>include</code>, I get a csv file downloaded with some errors planted in it (because <code>$wpdb</code> doesn't exist. And if comment out the <code>header</code>s, I get all my data printed to the page. </p> <p>So... any ideas what could be going on here?<br> Some obvious conflict of the wordpress environment and the proper creation of a file. </p> <p>Learning a lot, but no closer to an answer... Thinking I may need to just avoid the wordpress stuff and do a manual sql query. </p> |

22,002,428 | 0 | <p>Yes. You are doing the correct thing. Thats the short answer.</p> <p>However, if you are new to git, you might get caught or stuck, so I'll walk you through the process here.</p> <p>If you have not yet committed your changes you can do the following on the remote:</p> <pre><code>git stash git checkout -b my-new-branch-name master git stash apply git add . git commit -m 'committing new changes' git push origin my-new-branch-name </code></pre> <p>The git-stash command just stores your changes temporarily so you can checkout safely, and then git-stash apply reapplies them. This only works for uncommitted changes.</p> <p>If you have already committed your changes to master, you will want to simply create the branch the same way your original post says, but then you probably also want to remove your changes from the local master branch.</p> <pre><code>git branch my-new-branch-name master git reset --hard origin/master </code></pre> <p>This will create your new branch with the new commits, and then reset your local master branch to whatever was in the remote master branch.</p> <p>Now with that done, you can go to your local machine (or any other clone of the same repo), and pull down that branch.</p> <pre><code>git fetch git checkout my-new-branch-name </code></pre> |

13,058,432 | 0 | <p>Generally you'll have to fetch back out the <code>id</code> values of the inserted rows. This is unless you can create another key that is used in place of that which can be procedurally generated in advance.</p> <p>While <code>INSERT</code> statements with multiple rows is significantly faster, the price you pay is a lack of precision. If your <code>id</code> values are issued sequentially, which is the default behavior, then you can be reasonably assured that the <code>LAST_INSERT_ID()</code> represents the ID of the first row inserted, so you could perhaps calculate the ID of the rows using the method you propose, though starting at index 0.</p> <p>Remember that multiple submissions do not affect the <code>LAST_INSERT_ID()</code> result because this value is per-connection. It is only changed if you perform a subsequent query on the same database handle. Operations in other requests will not affect it.</p> <p>Databases that are clustered or multi-master may issue non-sequential identifiers in which case this won't work. This is also unreliable in an <code>INSERT IGNORE</code> situation where the number of rows actually inserted could be less than the number of rows provided.</p> |

Now we're back to trying to widen a Byte to a Long, and of course, the IS-A test fails.</p> </blockquote> <p>But that sounds like box and then widen and not widen and then box to me.</p> <p>Could anyone clarify the whole box and widen vs widen and box for me because as it stands the book isn't exactly clear on the issue.</p> <p>Edit: To clarify: I'm talking about pages 252 and 253 of the SCJP sun certified programmer for java 6 book. <a href="http://books.google.be/books?id=Eh5NcvegzMkC&pg=PA252#v=onepage&q&f=false" rel="nofollow noreferrer">http://books.google.be/books?id=Eh5NcvegzMkC&pg=PA252#v=onepage&q&f=false</a></p> |

13,748,350 | 0 | <p>Just to extend @ohmi's answer:</p> <ol> <li>You cannot prevent passes from being installed on more than one device - e.g. if user enables iCloud for Passbook, the passes will get synced automatically across devices.</li> <li>Considering your links to pkpasses are public, you may want to consider introducing one-time download links, but while it can fill your needs just fine, users can be really disappointed if it's impossible to re-add passes that they manually deleted. So I wouldn't recommend such solution. </li> <li>You can make you pkpass links kind of private, so only GET request originating from your application and carrying a specific value for specific header field (e.g. auth_token), will receive a pkpass file, however this way you almost disable pass distribution via email or via sharing URLs to passes and make pass updating probably impossible.</li> </ol> |

An instance of a subclass of this class is created by the client and handed to the data collector at the time of the initial request for data; this object is responsible for deciding (and telling the "collector") when enough data has been collected.</p> <pre><code>#include <string> // The class that decides when enough data has been collected // (Provided to class "collector" by its clients) class evaluator { public: virtual ~evaluator() {}; // Notification callbacks; Returning *this aids in chaining virtual evaluator& name_collected() { return *this; } virtual evaluator& age_collected() { return *this; } virtual evaluator& sex_collected() { return *this; } virtual evaluator& location_collected() { return *this; } // Returns true when sufficient data has been collected virtual bool enough() = 0; }; // The class that collects all the data class collector { public: void collect_data( evaluator& e ) { bool enough = false; while ( !enough ) { // Listen to data source... // When data comes in... if ( /* data is name */ ) { name = /* store data */ enough = e.name_collected().enough(); } else if ( /* data is age */ ) { age = /* store data */ enough = e.age_collected().enough(); } /* etc. */ } } // Data to collect std::string name; int age; char sex; std::string location; }; </code></pre> <p>In your example, you wanted a particular client to be able to specify that the combination of <code>age</code> and <code>sex</code> is sufficient. So you subclass <code>evaluator</code> like so:</p> <pre><code>class age_and_sex_required : public evaluator { public: age_and_sex_required() : got_age( false ) , got_sex( false ) { } virtual age_and_sex_required& age_collected() override { got_age = true; return *this; } virtual age_and_sex_required& sex_collected() override { got_sex = true; return *this; } virtual bool enough() override { return got_age && got_sex; } private: bool got_age; bool got_sex; }; </code></pre> <p>The client passes an instance of this class when requesting data:</p> <pre><code>collector c; c.collect_data( age_and_sex_required() ); </code></pre> <p>The <code>collect_data</code> method quits and returns when the <code>age_and_sex_required</code> instance reports that the amount of data collected is "enough", and you haven't built any logic, knowledge, enums, whatever, into the <code>collector</code> class. Also, the logic of what constitutes "enough" is <em>infinitely configurable</em> with no further changes to the <code>collector</code> class.</p> <p>----- EDIT -----</p> <p>An alternate version would <em>not</em> use a class with the <code>..._collected()</code> methods but simply a single (typedef'd) function that accepts the <code>collector</code> as a parameter and returns <code>boolean</code>:</p> <pre><code>#include <functional> typedef std::function< bool( collector const& ) > evaluator_t; </code></pre> <p>The code in <code>collector::collect_data(...)</code> would simply call</p> <pre><code>enough = e( *this ); </code></pre> <p>each time a piece of data is collected.</p> <p>This would eliminate the necessity of the separate <code>evaluator</code> abstract interface, but would add dependence on the <code>collector</code> class itself, as the object passed as the <code>evaluator_t</code> function would be responsible for checking the state of the <code>collector</code> object to evaluate whether enough data has been collected (and would require the <code>collector</code> to have sufficient public interface to inquire about its state):</p> <pre><code>bool age_and_sex_required( collector const& c ) { // Assuming "age" and "sex" are initialized to -1 and 'X' to indicate "empty" // (This could be improved by changing the members of "collector" to use // boost::optional<int>, boost::optional<char>, etc.) return (c.age >= 0) && (c.sex != 'X'); } </code></pre> |

564,591 | 0 | <p>My simple answer combined with those answer is:</p> <ul> <li>Create your application/program using thread safety manner </li> <li>Avoid using public static variable in all places</li> </ul> <p>Therefore it usually fall into this habit/practice easily but it needs some time to get used to: </p> <p>program your logic (not the UI) in functional programming language such as F# or even using Scheme or Haskell. Also functional programming promotes thread safety practice while it also warns us to always code towards purity in functional programming. If you use F#, there's also clear distinction about using mutable or immutable objects such as variables. </p> <hr> <p>Since method (or simply functions) is a first class citizen in F# and Haskell, then the code you write will also have more disciplined toward less mutable state. </p> <p>Also using the lazy evaluation style that usually can be found in these functional languages, you can be sure that your program is safe fromside effects, and you'll also realize that if your code needs effects, you have to clearly define it. IF side effects are taken into considerations, then your code will be ready to take advantage of composability within components in your codes and the multicore programming.</p> |

10,781,084 | 0 | If my app deletes a post it made to a user's wall, will all likes and shares made by other people also be deleted? <p>Lets say I have a FB app I've created, and for whatever reason the server code for the app is responsible for posting stories to the app user's wall (using a token).</p> <p>Now let's say we want to take down that post at a later date - easy, right? Because the app created the post, it owns it, and using the ID it received originally it can take that post down. (I presume the ID I get back is actually an "object id" referring to my content, rather than specifically to the post on the user's wall - correct?)</p> <p>Here's the thing though. What if one or more friends of the user shared that story to their own wall - what if this happened a number of times, spreading through the friend relationship tree further and further. Does my app still have the power to remove all of these posts, because it created the original post?</p> <p>Additionally, what if the original user deleted the post themselves from their wall, but not until it had been shared by his/her friends? Would this have the same effect (delete everywhere), or would it only be that one specific post being removed? Would my app get an error when it tried to delete the post itself if the post had already been deleted by the user? </p> <p>The reason I ask is because, if my app deleted the original post that it made to the user's wall, I would want <em>all</em> of the shared posts or likes to also be deleted, no matter where they were down the friend chain. I don't want to delete my original post and assume all is well, only to discover that because it was shared several times down the chain that it is still visible somewhere. </p> <p>In case it's relevant, the "post" my app will make would require a custom image and a specific return URL - I tried the <code>/user_id/links</code> graph API and it didnt work (there's a bug with it). So I'd be most likely using <code>/user_id/feed</code> to make the post.</p> |
