PHP Built-in Functions
Aug 23, · Calling a PHP function using the HTML button: Create an HTML form document which contains the HTML button. When the button is clicked the method POST is called. The POST method describes how to send data to the server. After clicking the button, the array_key_exists () function called. You can't call PHP directly from HTML - PHP is only run on the server, typically to generate HTML. You could make an XHR request to a server, and implement the server side in PHP. Sep 14, · Options +Includes AddOutputFilter datingyougirl.com SetEnv TZ America/Los_Angeles Then your datingyougirl.com file can look like this: html> php" --> html> datingyougirl.com looks like this: php echo date("g:i A T e");?> The following will be displayed: PM PDT America/Los_Angeles.
Okay, admittedly, this is a pretty crazy and virtually useless tip. Back when I worked for a Toronto web design agency, we often had to update sites that were written in straight HTML, with no server-side programming at all. So every year, clients that owned such sites would ask us to update all the pages to display the current copyright year. That was pretty lame. Not exactly the kind of work we wanted to be doing.
So we wanted to create a way that the current year would be printed on each page automatically. So we did something like this:. But I thought this was a great example of some really crafty thinking, and it helped us get out of a little jam, while still utilizing server-side resources on a static site.
It also minimized the amount of code used. Are there any security issues with this? I really have no idea. I believe there are tracking applications and web counters that have used this approach. Would be interested to hear if anyone has any input on this. I just implemented it at the time. It is a copyright after all. Not sure if anyone would be able to use the copyrighted work and claim it had expired and they could always modify the source of the page to display whatever the hell they want … but still… using the server date gives the programmer better control over the page look.
If JS detected that the account was less than 5 minutes old and that the page had been viewed 2 times or less due to refreshes, coming back to the overview page via link, etc it showed a welcome message. I would also recommend adding a header call to declare the content type within the php. Although the script tag likely guesses it correctly, it never hurts to be more thorough. And I cannot think of any browser that does not support iframes.
The post kept me interested. Oh, of course. XSSI has many features, including pattern matching. Many web sites work just fine without a database back end, especially if they use the database simply to store documents. In fact, you can even build a light content management system using XSSI. Thanks for the info. But of course, in PHP, you have the option of setting the time zone in the code. Well, those requests came from the project managers, who get them from the client. Ok now I can see where this could grow to be something more.
My HTML file looks like this:. I tried running this, but the time does not display. Is my HTML file set up correctly? Is there something I need to set in. It does require that you set up SSI on the server.
The first two lines I added to. The SetEnv line in. When it comes to how my little mind grasp a concept, this one is by far the best tip on including a php file in this manner.
