Can someone help me with a javascript?

My site has a javascript that creates an image. I would like to know what images are created on my site, by saving the file names on my server. I tried making the javascript create a hidden element and then saving the file through PHP, but it's not working. Can someone help me with a javascript that saves the new image's file name on the server?

 

It is not possible to achieve in Javascript. Javascript executes on the client site (in the browser) and so it does not have access to the server resources, i.e. file system. You will need to use some server side programming to achieve that (PHP, ASP.NET, etc)

 

W/E, anything that can work with the javascript. The PHP that I thought would work isn't, so I need to figure out some other way.

 

You'll need to use some form of submission to achieve this. Are you looking to save the images themselves to the database, or just tag names/IDs, etc.?

Either way, you can submit the correct value using an HTML form or you can use AJAX. Personally, I'd use AJAX because it allows for a smoother user experience, speeds up the time it takes to achieve the desired result and is probably less code in the end. An AJAX function along the lines of this should work:

Code (markup):

Now in your PHP file (some_page.php), you'll need to use the $_GET superglobal to retrieve the "something" parameter, whereupon you can store it in the database.

I wrote a tutorial on how to check username availability with AJAX a while ago, all the code necessary to send HTML data to PHP via JavaScript is explained, but you'll have to work the code to your needs. If you're interested, check username availability with AJAX.

 

I think this is going to where I want to go. Suppose I just want to save all the names in one file so that I can review them at a later date. How do I write to the file and then close the file?

 

I need a solution for this myself

 

with jQuery is easier

/* in your javascript */
$.ajax({
type:"POST",
url: "/youractionscript.php",
data: {picname: "your pic name"},
async: false,
success: function(data){
return;
}
});


/* in youractionscript.php */
if(isset($_POST['picname'])){
do whatever you want with $_POST['picname'];
}
