quick question regarding the use of POST values and links

[nikefido]

I have so far only seen POST values used with form data / submit buttons - I'm assuming you can't make a regular link (aka anchor tag) send POST data when it is clicked?

 

The only solution I know would be to use JS to "AJAX" it (although you can set the JS function to send the info synchronously so it actually does reload the page!)

Actually, if i'm understanding your question, using 'POST' creates an array of the form data that can be manipulated in the form processing code. If you want to pass parameters via the url then you would use 'GET' to snag the info and use it. Like this:

 

www.yoursite.com/page.php?memberid=333

 

Then use:

 

$memberid = $_GET['memberid'];

 

To do things like:

 

echo $memberid;

 

of insert into database, extract from database based upon that id, etc. etc. etc.

right, i know all this - i guess i was just wondering if you could use POST with a regular anchor (link) somehow - which I've assumed is "no" - but never hurts to ask, right?

Well, in a way you can. Not using the typical <a href> tag, though. You would use it in your 'action' tag in the form:

 

action="nameofpage.php?memberid=$_POST['memberid']"

 

which would pass along the data. You can string as many items as you wish on the end of your url.

fair enough, thanks, guess i'll call this topic closed.
