  • Best method to cache objects in PHP?

    - by Martin Bean
    Hi, I'm currently developing a large site that handles user registrations. A social networking website for argument's sake. However, I've noticed a lag in page loads and deciphered that it is the creation of objects on pages that's slowing things down. For example, I have a Member object, that when instantiated with an ID passed as a construct parameter, it queries the database for that members' row in the members database table. Not bad, but this is created each time a page is loaded; and called more than once when say, calling an array of that particular members' friends, as a new Member object is created for each friend. So on a single page I can have upwards of seven of the same object, but containing different properties. What I'm wanting to do is to find a way to reduce the database load, and to allow persist objects between page loads. For example, the logged in user's object to be created on login (which I can do) but then stored somewhere for retrieval so I don't have to keep re-creating the object between page loads. What is the best solution for this? I've had a look at Memcache, but with it being a third-party module I can't have the web host install it on this occasion. What are my alternatives, and/or best practices in my case? Thanks in advance.

  • Is canvas security model ignoring access-control-allow-origin headers?

    - by luklatlug
    It seems that even if you set the access-control-allow-origin header to allow access from mydomain.org to an image hosted on domain example.org, the canvas' origin-clean flag gets set to false, and trying to manipulate that image's pixel data will trigger a security exception. Shouldn't canvas' obey the access-control-allow-origin header and allow access to image's data without throwing an exception?

  • JQuery or Javascript solution for selecting default value in drop down

    - by user1446843
    I have a calender list in a webpart page, this webpart page has a version number in it's title e.g. "WebPart 1.62". What I need to do is when a New item is created in the calender list on a webpart page, the New Item form has a dropdown menu 'SystemID' which gets it's values from the title column of a 'Systems' list, which is pre-populated with all versions of webpart forms. This dropdown menu 'SystemID' should select the version of the webpart page it is in as the default value. I need a JQuery solution for this, or even Javascript. I am finding it difficult as I am new to both JQuery and Sharepoint. I am using SP2007. I'll appreciate any guidance in solving this. At the moment the Create New Item form of the Calender list has the 'SystemID' drop down list pre-populated with the versions from the Systems list. If anyhthing is unclear pls let me know and I'll explain in more detail.

  • Dynamic web widget

    - by user1824996
    My vendor offers a widget creation service where I can login to their page, set initial values of a search form, after the save button is clicked, I can copy & paste the script code on my website to display a product search result widget. I am thinking to change this static widget to a dynamic one. Since my programming knowledge is limited, can experts tell me if it's possible to login https remotely (using cURL) and set search form values equal to values on my page (every time my page content changes, it will change the form value), then save the form. So the widget script I pasted on my page will always be refreshed to new search result. So the issue will involve cross domain, form submission & server/browser communication. I know a little jQuery, PHP, Ajax, cURL but so far I stuck with just having an idea but not really sure how to implement it.

  • How to resubmit PHP form with javascript

    - by user866339
    I am wondering if it is possible to to resubmit a form with a button click that calls up a javascript command. So this is basically what I'm trying to do - page 1: form; action = page2.php page 2: generate a randomized list according to parameters set by page 1 I would like to place a button on page 2 so that on click, it would be as if the user has hit F5, and a new list would be generated with the same parameters. I found a lot of help on Google with people trying NOT to get this to happen, but I'm not sure how to actually get it to happen..... Thank you!

  • 100% height for multiple divs

    - by kilrizzy
    I usually have my structure laid out something like this: <div id="all"> <div id="page"> <div id="header"></div> <div id="content"></div> <div id="footer"></div> </div> </div> Where the body will hold a background pattern, "all" will hold a dropshadow for the page going up and down, and "page" may often have a repeating-y background as well. I have tried variations on using the css height/min-height properties: html, body { height:100%; ... } #all { height:100%; min-height:100%; } #page { height:100%; min-height:100%; height:auto !important; } It seems like if I remove height:auto from "all" then it seems like it works UNTIL you scroll, then after the scroll the background for all dissappears example However if I keep the height:auto there then I get the problem of the background for page not working example Hopefully someone knows a fix?
