  1. Hi All, I am presently using a Debian VPS to which, if I need, I can add another disk. In my website, users can upload images, that are then stored in the primary disk into a child directory of a directory called httpdocs. Instead of the primary disk, would it be possible to have them stored in a secondary disk ? I am asking this because I am not sure that a user connected to my website is allowed to run a PHP script intended to write a file in a directory that actually does not belong to the httpdocs directory. Thanks
  2. The maximum number of subarrays is 12, and each may contain up to 20 values.
  3. Hi All, Suppose I have the following array, with a series of subarrays. Is there a quicker/better way than the one below to delete the subarrays whose ALL values are contained in another subarray ? Thanks! $global_array = array( $sub_array1 = array ( 0 => 8661, 1 => 8662 ), $sub_array2 = array ( 0 => 8662 ), $sub_array3 = array ( 0 => 8667, 1 => 8770 ), $sub_array4 = array ( 0 => 8672, 1 => 8770, 2 => 8772, ), $sub_array5 = array ( 0 => 8706, 1 => 8707, 2 => 8805, ), $sub_array6 = a
  4. Hi All, I want to insert a Google static map. I noticed that there may be some loss of information (e.g., loss of the name of narrow streets) when using lower value for the size attribute of the map. For example, http://maps.googleapis.com/maps/api/staticmap?&size=600x600 may show more details than http://maps.googleapis.com/maps/api/staticmap?&size=150x150. On the other hand I want the static map to display on smartphones, adjusted to their width. With some JS I could get the width of the smartphone and inject it in the size attribute, but that could lead to some loss of det
  5. Thanks. mysqldump -uroot -p --databases db_name --routines --events --result-file=file_name.sql did the trick.
  6. Hi All, I am in the process of moving my database from a local Windows system to a Debian VPS server. So far to back up my database I have been using this syntax : mysqldump -uroot -p --databases database_name --routines --events> filename.sql In this page http://www.it-iss.com/mysql/mysql-copying-a-database-users-and-privileges-between-two-servers/ the author recommends to use also the --result-file to prevent line end issues when moving from a Windows system to a Linux system. Would the right syntax be as follows then ? mysqldump -uroot -p --databases d
  7. Well, so far, I tried nothing, as for spanish lists of words. It is just that googling terms like "SPANISH_COLLATION" gives no result. For example, when properly ordered in Spanish, "lleno" would come after "lomo", and "chico" after "cosa", since the alphabet order in Spanish is "a, b, c, ch, d, ....k, l, ll, m, n, ...z"
  8. Hi All, I want to display lists of words (utf8 encoded) correctly ordered in Spanish, where "ch" and "ll" are considered as letters in the alphabet. For French, I use the following : $col = new Collator('fr_FR'); $col->setAttribute(Collator::FRENCH_COLLATION, Collator::ON); $col->asort(<array-to-sort>); What would be the equivalent for spanish? Thanks!
  9. Hi All, I have a page organized in tabs, each with its own div. I have a js that displays a given div when the user clicks the matching tab. There is a leaflet map in the first div, built from thousands of markers. There is a login form in the other div. Displaying a div by clicking its tab works great. If the user fails the login process, the page is reloaded and he is redirected back to the login div (and a message displays about the error that occured). Now here is the issue. Suppose the login process fails. If the user clicks the map tab,
  10. You are right. My mistake. I am using phpMyAdmin. I should have made the tests through SQL statements instead of inserting a row via the Insert tab or editing a value via the View tab.
  11. Hi All, I have a table to which I added 2 computed columns like this : ALTER TABLE foo add number2 DECIMAL GENERATED ALWAYS AS (number*2) STORED, add nombre3 DECIMAL GENERATED ALWAYS AS (number*3) STORED Two issues : 1. Updating a value in "number" column does not updates "number2" and "number3" columns 2. Inserting a new row generates the error "the value specified for generated column is not allowed". Thanks!
  12. Hi All, I am presently working on media queries. Is there a reliable way to assess the physical width in inches of the screen ? On my 17-inches laptop, at a 1920-px resolution, I have a web page that displays a series of divs, with 4 divs per row. At a 1366-px resolution, the same page will display 3 divs per row. (Reducing the divs’ size in order to have 4 divs per row would make them less readible.) However, there are screen devices wider than 17 inches, but with a 1366-px resolution. On those screens, displaying 4 divs per row, instead of 3, would be appro
  13. Hi All, Just wondering whether it is possible to resize a jpg image to a specific size in bytes (while preserving height/width ratio). Thanks for any clues!
  14. Hi All, I have a function that I want to trigger multiple times on different parts of the document, with a 1 second delay between each run. The structure of the function is as follows function intro(param1, param2){ //processing goes here }; I call it like this : $(document).ready(function(){ intro('#hello', '#world'); intro('#hi', '#all'); intro('#hola', '#amigos'); }); I would like to trigger intro('#hi', '#all') 1 second after intro('#hello', '#world') starts, and intro('#hola', '#amigos') 1 second after intro('#hi', '#all') start
