Pass selected date back to PHP from javascript

[sleeper24]

Hi there,

I have little problem I'm facing. I have a calendar and when the user selects a day, it shows the selected date. However, I can't seem to pass that selected date back to a php script.

This is the function that prints the selected date:

     if (this.selectHandler) {
          this.selectHandler(this, this.date.print(this.dateFormat))  // Prints the selected date to the screen.
	  var dateSelected = this.selectHandler(this, this.date.print(this.dateFormat))

	  location.href="getSelectedDate.php?selectedDate="+dateSelected  // This is where I pass to the php script
     }

However, I can't seem to pass that selected date back to a php script.

You can not pass a javascript variable to a php script. You may pass a value to a database (via a classic submit or AJAX technique), from where the php application might read it. Javascript is a client-side language, while php is a server-side one. They can not interfere the way you have mentioned.

I got it to work. Here is the code. Although I don't know if it is legal or standard.

var dateSelected = this.date.print(this.dateFormat);
var page = document.title;
location.href="getSelectedDate.php?selectedDate="+dateSelected+"&page=" +page;

I think what you're looking for is the PHP equivalent of ASP's postback. You can fake it by submitting the page as a form (with itself as the action) and having PHP read the data from $_POST["selectedDate"]

edit: looking at your last post, there might have been an invalid character in the dateSelected variable that couldn't be passed in the URL (like "/") -- can you give us an example of what the new output is?

Alzheimers,

So this is the code that I could not pass the date back.

if (this.selectHandler) {
          this.selectHandler(this, this.date.print(this.dateFormat))  // Prints the selected date to the screen.
	  var dateSelected = this.selectHandler(this, this.date.print(this.dateFormat))

	  location.href="getSelectedDate.php?selectedDate="+dateSelected  // This is where I pass to the php script
     }

What I changed from that code was I remove the "this.selectHandler(this, " from this:

var dateSelected = this.selectHandler(this, this.date.print(this.dateFormat))

Here is what it looks like after I removed that piece of code.

var dateSelected = this.date.print(this.dateFormat);

Then you can use the "location.href " to pass it to a php file like I did above.
