Changing backgrounds, pictures, CSS or files on a fly
A couple of years ago I started a project on Minds-eye.ning.com that rotated backgrounds. At first I thought it was great but then I noticed that the hits from switching created a massive delay actually Jen’s from Jen Social pointed it out. I was quite puzzled how to overcome this time delay. From my experience as a programmer (none Internet) I knew I could change the address of something by giving it a common address but I wasn’t sure how to do it.
A few weeks ago I was experimenting using my webhost “fatcow” and found I could use a common address and overwrite a file (using a common file) Then I took it a step further and created a php file that listed all my backgrounds then used an if than statement to determine which background should be displayed. Finally, I had to figure out how I was going to execute the php on a fly and then it all came together.
You can see this by on http://Minds-eye.ning.com in the morning and afternoon, which is when I call the php to change the background.
To make the backgrounds or files change you need to do the following steps.
- Make sure the background or file works to begin with.
- Pick a common name for the master file
- Go to Jen Social and grab these files http://jensocial.com/group/socialnetworktips/forum/topics/scheduling-background-changes
- Look how it is laid out and edit it to meet your needs, If you have problems or don’t understand it email me at Ralph_us@hotmail.com I will help you
- Have some way of running the php file. If you webhost doesn’t have an auto execute then the next best thing is using http://www.setcronjob.com/ which is a free service to schedule a job.
- Then add the master common to your CSS so it can switch on a fly and Ning would never know the difference.
Sometimes when you change the background you need to change the xg_body or Nav bar or sign in image this is all done in the same timed program. You just need to test for what background will be used and use a ref to select it and add it to the program.
I get a lot of my code from Jen Social, and if you haven’t joined, it would benefit you to. Her code is well tested. So, I have been working on a new CSS layout and grabbed some of her stuff and realized if I do backgrounds on a fly I can change a lot of stuff at once. Little more advanced lol.
If you decide to use the code, you might want to donate a few dollars to Minds-eye.ning.com and definitely join our site to see talented artist at work. If not it’s okay, since Jen shares with me I will share with you.
