  • mySQL - One large query vs Ajax indivdual queries

    - by Mark
    Hi guys, I guess no one will have a definative answer to this but considered predictions would be appriciated. I am in the process of developing a mySQL database for a web application and my question is: Is it more efficient to make a single query that returns a single row using AJAX or To request 100 - 700 rows when the user will likely only ever use the results of two or three? Really I am asking what is heavier for the server 2-3 requests with one result or 1 request with 100 - 700 results? Thanks, Mark

What i want to know how to show content(mysql) inside a div when you click on a link. There will be 8-10 links and clicking on each should fetch its corresponding products. So for example category 1 | category 2 | category 3 show [products from category 1] when clicked on "category 1" and same way for the other two. the problem is the url for each link will have the category id so when clicked it will fetch its own products inside this div. Can someone please guide me with an example available online? looking for some thing that can dynamically fetch contents from mysql inside this div. content change is based on the category id in the url of the links I am clicking on. regards

    Hi, I am developing one website using cakephp and jquery technologies. Server-side there are some functions which handles sql queris. As per requirement I want to modify server side functions on client side using jquery AJAX call. E.g. : Below is the function on server side to modify users information. function modifyUser(username,userid) { //update query statements } Then jquery AJAX call will be like this : $.ajax({ url: 'users/modiyUser', success: function() { alert("Updation done") or any statements. } }); and I want to modify above i.e. server side function depending upon client input criteria. $.ajax({ function users/modiyUser(username,userid) { // I will write here any other statements which gives me some other output. } }); Above AJAX call syntax may not present, but i think you all understood what I am trying to do I simply wants to modify/override server side functions on client side.

  • MYSQL and the LIMIT clause

    - by Lizard
    I was wondering if adding a LIMIT 1 to a query would speed up the processing? For example... I have a query that will most of the time return 1 result, but will occasionaly return 10's, 100's or even 1000's of records. But I will only ever want the first record. Would the limit 1 speed things up or make no difference? I know I could use GROUP BY to return 1 result but that would just add more computation. Any thoughts gladly accepted! Thanks

  • Preventing spam bots on site?

    - by Mike
    We're having an issue on one of our fairly large websites with spam bots. It appears the bots are creating user accounts and then posting journal entries which lead to various spam links. It appears they are bypassing our captcha somehow -- either it's been cracked or they're using another method to create accounts. We're looking to do email activation for the accounts, but we're about a week away from implementing such changes (due to busy schedules). However, I don't feel like this will be enough if they're using an SQL exploit somewhere on the site and doing the whole cross site scripting thing. So my question to you: If they are using some kind of XSS exploit, how can I find it? I'm securing statements where I can but, again, its a fairly large site and it'd take me awhile to actively clean up SQL statements to prevent XSS. Can you recommend anything to help our situation?

The second piece of sample code returns valid results. Do to the nature of this project though I need to pass the id number as they are stored in SESSION variables. What am I missing?

  • array_merge vs array_value for resetting array index

    - by Jamex
    I have 1 array that I want to re-index. I have found that both array_values and array_merge functions can do the job (and I don't need 2 arrays for the array_merge function to work). Which is faster for a very large array? I would benchmark this, but I don't know how and don't have the large array yet. Before re-index: Array ( [0] => AB [4] => EA [6] => FA [9] => DA [10] => AF ) After re-index: Array ( [0] => AB [1] => EA [2] => FA [3] => DA [4] => AF )

  • How to Sync CI (Hudson) Activity into an existing automated Build Process (phing, svn)?

    - by maraspin
    OUR CURRENT BUILD PROCESS We're a small team of developers (2 to 4 people depending on project) who currently use Phing to deploy code to a staging environment, before going live. We keep our code in a SVN repo, where the trunk holds current active development and, at certain times, we do make branches that we test and then (if successful), tag and export to the staging env. If everything goes well there too, we finally deploy'em in production servers. Actions are highly automated, but always triggered by human intervention. THE DOUBT We'd now like to introduce Continuous Integration (with Hudson) in the process; unfortunately we have a few doubts about activity syncing, since we're afraid that CI could somewhat interfere with our build process and cause certain problems. Considering that an automated CI cycle has a certain frequency of automatically executed actions, we see 2 possible cases for "integration", each with its own problems: Case A: each CI cycle produces a new branch with its own name; we do use such a name to manually (through phing as it happens now) export the code from the SVN to the staging env. The problem I see here is that (unless specific countermeasures are taken - IE deletion) the number of branches we have can easily grow out of control (let's suppose we commit often, so that we have a fresh new build/branch every N minutes). Case B: each CI cycle creates a new branch named 'current', which is then tagged with a unique name only when we manually decide to export it to staging; the current branch, at any case is then deleted, as soon as the next CI cycle starts up. The problem we see here is that a new cycle could kick in while someone is tagging/exporting the 'current' branch to staging thus creating an inconsistent build (but maybe here I'm just too pessimist, since I confess I don't know whether SVN offers some built-in protection against this). With all this being said, I was wondering if anyone with similar experiences could be so kind to give us some hints on the subject, since none of the approaches depicted above looks completely satisfing to us. Is there something important we just completely left off in the overall picture? Thanks for your attention & (in advance) for your help!

  • Checking for valid email addresses

    - by Roland
    I'm running a website with more than 60 000 registered users. Every week notifications are send to these users via email, now I've noticed some of the mail addresses do not exists anymore eg. the domain address is valid but the email name en asdas@ is not valid anymore since person does not work at a company anymore etc. Now I'm looping through the database and doing some regular expression checks and checking if the MX records exist with the following two functions function verify_email($email){ if(!preg_match('/^[_A-z0-9-]+((\.|\+)[_A-z0-9-]+)*@[A-z0-9-]+(\.[A-z0-9-]+)*(\.[A-z]{2,4})$/',$email)){ return false; } else { return true; } } // Our function to verify the MX records function verify_email_dns($email){ list($name, $domain) = split('@',$email); if(!checkdnsrr($domain,'MX')){ return false; } else { return true; } } If the email address is in an invalid format or the domain does not exists I delete the users account. Are there any methods I could use to check if the email address still exists or not if the domain name is valid and the email address is in the correct format? For example [email protected] does not exist anymore but test.com is a valid domain name.

  • I'm working on a website that sells different artwork, what's the best way to handle different image

    - by ThinkingInBits
    I'm working on a website that will allow users to upload and sell their artwork in different sizes. I was wondering what the best way would be to handle the different file sizes automatically. A few points I was curious on: How to define different size categories (small, medium, large) in such a way that I'll be able to dynamically re-size images with proportional dimensions. Should I store actual jpegs of the different sizes for download? Or would it be easier to generate these different sizes for download on the fly My thumbnails will be somewhat larger than your average thumbnails, should I store a second 'thumbnail image' with the sites watermark overlaying it? Or once again, generate this on the fly? All opinions, advice are greatly appreciated!

  • Target module with custom layout in Magento

    - by dardub
    In my custom module, I'd like to include an extra block and style sheet that targets only pages within my custom module. So that when i access myserver.com/configurator/ Pages will use the correct template I specified In the catalog.xml file, I noticed <catalog_category_default> That seems to be what I am looking for, so I tried: <configurator_default_default> <reference name="root"> <action method="setTemplate"><template>configurator/2columns-right.phtml</template></action> </reference> <reference name="head"> <action method="addCss"><stylesheet>css/configurator.css</stylesheet></action> </reference> <reference name="content"> <block type="configurator/guide" name="timeline" template="configurator/guide/timeline.phtml" /> </reference> </configurator_default_default> But it doesn't change the template for pages within the module. I also tried <configurator_guide_default> But it doesn't pick up the correct template If i put it within the specific page such as <configurator_guide_page1> Then it works.
