  • How to return a value into webpage

    Hello: I have a simple webpage that displays the credit balance for calling cards. So far without any problems, with HTML, PHP and mysql, I was able to retrieve the balance from a data base. But I have to display the result in ANOTHER PAGE, wich looks akward because the page must reload. Can I just load this value into a pre-drawed field under the input fields that collect the data from the customer? Such as : Account Number: 134556 PIN: * |send| Balance is: $12.36 Thanks in advanced

  • Defined variables and arrays vs functions in php

    - by Frank Presencia Fandos
    Introduction I have some sort of values that I might want to access several times each page is loaded. I can take two different approaches for accessing them but I'm not sure which one is 'better'. Three already implemented examples are several options for the Language, URI and displaying text that I describe here: Language Right now it is configured in this way: lang() is a function that returns different values depending on the argument. Example: lang("full") returns the current language, "English", while lang() returns the abbreviation of the current language, "en". There are many more options, like lang("select"), lang("selectact"), etc that return different things. The code is too long and irrelevant for the case so if anyone wants it just ask for it. Url The $Url array also returns different values depending on the request. The whole array is fully defined in the beginning of the page and used to get shorter but accurate links of the current page. Example: $Url['full'] would return "http://mypage.org/path/to/file.php?page=1" and $Url['file'] would return "file.php". It's useful for action="" within the forms and many other things. There are more values for $Url['folder'], $Url['file'], etc. Same thing about the code, if wanted, just request it. Text [You can skip this section] There's another array called $Text that is defined in the same way than $Url. The whole array is defined at the beginning, making a mysql call and defining all $Text[$i] for current page with a while loop. I'm not sure if this is more efficient than multiple calls for a single mysql cell. Example: $Text['54'] returns "This is just a test array!" which this could perfectly be implemented with a function like text(54). Question With the 3 examples you can see that I use different methods to do almost the same function (no pun intended), but I'm not sure which one should become the standard one for my code. I could create a function called url() and other called text() to output what I want. I think that working with functions in those cases is better, but I'm not sure why. So I'd really appreciate your opinions and advice. Should I mix arrays and functions in the way I described or should I just use funcions? Please, base your answer in this: The source needs to be readable and reusable by other developers Resource consumption (processing, time and memory). The shorter the code the better. The more you explain the reasons the better. Thank you PS, now I know the differences between $Url and $Uri.

  • Does rails do a rollback if I use begin...rescue?

    - by codeman73
    I'd like to add a begin...rescue block to one of my controllers create method, in order to log better info and construct the correct error message to return to the client. Does the rescue in any way 'interrupt' the rollback process? I'm assuming rails automatically does a rollback. When does it happen? Has it already happened by the time I get in the rescue clause? I'm using mySQL on Dreamhost and I think they use innoDB.

  • how to bind parameters correctly in example below in mysqli?

    - by user1421767
    In old mysql code, I had a query below which worked perfectly which is below: $questioncontent = (isset($_GET['questioncontent'])) ? $_GET['questioncontent'] : ''; $searchquestion = $questioncontent; $terms = explode(" ", $searchquestion); $questionquery = " SELECT q.QuestionId, q.QuestionContent, o.OptionType, an.Answer, r.ReplyType, FROM Answer an INNER JOIN Question q ON q.AnswerId = an.AnswerId JOIN Reply r ON q.ReplyId = r.ReplyId JOIN Option_Table o ON q.OptionId = o.OptionId WHERE "; foreach ($terms as $each) { $i++; if ($i == 1){ $questionquery .= "q.QuestionContent LIKE `%$each%` "; } else { $questionquery .= "OR q.QuestionContent LIKE `%$each%` "; } } $questionquery .= "GROUP BY q.QuestionId, q.SessionId ORDER BY "; $i = 0; foreach ($terms as $each) { $i++; if ($i != 1) $questionquery .= "+"; $questionquery .= "IF(q.QuestionContent LIKE `%$each%` ,1,0)"; } $questionquery .= " DESC "; But since that old mysql is fading away that people are saying to use PDO or mysqli (Can't use PDO because of version of php I have currently got), I tried changing my code to mysqli, but this is giving me problems. In the code below I have left out the bind_params command, my question is that how do I bind the parameters in the query below? It needs to be able to bind multiple $each because the user is able to type in multiple terms, and each $each is classed as a term. Below is current mysqli code on the same query: $questioncontent = (isset($_GET['questioncontent'])) ? $_GET['questioncontent'] : ''; $searchquestion = $questioncontent; $terms = explode(" ", $searchquestion); $questionquery = " SELECT q.QuestionId, q.QuestionContent, o.OptionType, an.Answer, r.ReplyType, FROM Answer an INNER JOIN Question q ON q.AnswerId = an.AnswerId JOIN Reply r ON q.ReplyId = r.ReplyId JOIN Option_Table o ON q.OptionId = o.OptionId WHERE "; foreach ($terms as $each) { $i++; if ($i == 1){ $questionquery .= "q.QuestionContent LIKE ? "; } else { $questionquery .= "OR q.QuestionContent LIKE ? "; } } $questionquery .= "GROUP BY q.QuestionId, q.SessionId ORDER BY "; $i = 0; foreach ($terms as $each) { $i++; if ($i != 1) $questionquery .= "+"; $questionquery .= "IF(q.QuestionContent LIKE ? ,1,0)"; } $questionquery .= " DESC "; $stmt=$mysqli->prepare($questionquery); $stmt->execute(); $stmt->bind_result($dbQuestionId,$dbQuestionContent,$dbOptionType,$dbAnswer,$dbReplyType); $questionnum = $stmt->num_rows();

  • How to disable activerecord cache logging in rails

    - by user1508459
    I'm trying to disable logging of caching in production. Have succeeded in getting SQL to stop logging queries, but no luck with caching log entries. Example line in production log: CACHE (0.0ms) SELECT merchants.* FROM merchants WHERE merchants.id = 1 LIMIT 1 I do not want to disable all logging, since I want logger.debug statements to show up in the production log. Using rails 3.2.1 with Mysql and Apache. Any suggestions?

  • Moving .JS files to a CDN: How to manage AJAX requests?

    - by pagewil
    I am thinking of moving my static .JS files to a CDN such as Amazon S3 for performance reasons. As my PHP files and mySQL DB remain on my primary hosting domain what is the best way to manage my JS AJAX requests if they are now cross domain? Currently they look like this within my .JS file (with relative paths): $.ajax({ type: "POST", url: "/myNearbyPhpFile.php", data: {data:someData}, success: function($r){} });

  • What is the standard or best way to deal with database branching with Mercurial or Git branches?

    - by Chad Johnson
    This has been a big question mark on my mind. I'm moving to Mercurial or Git very soon for my web software, and sometimes my branches require significant database changes which other branches should not see. This, I can't always share the same database for my branches. Is there some standard way of dealing with database changes for branching and cloning? What do you all do? I'm using MySQL.

  • how can I easily upload outlook contacts into my web application?

    - by Angela
    Hi, I am trying to find a way for our users to very easily upload their outlook contacts into our web application (mysql database). I'm not sure where to begin. I've seen various tools which are pretty complex. I am open to existing third-party solutions, but my hope is that there is something which is very simple to use or build. Thanks. PS: Ideally, it would not involve using visual basic.

  • Is a server an infinite loop running as a background process?

    - by Tony
    Is a server essentially a background process running an infinite loop listening on a port? For example: while(1){ command = read(127.0.0.1:xxxx); if(command){ execute(command); } } When I say server, I obviously am not referring to a physical server (computer). I am referring to a MySQL server, or Apache, etc. Full disclosure - I haven't had time to poke through any source code. Actual code examples would be great!
