Passing Variables to PHP via Javascript

[INTELImaxx]

Greetings,
Im getting a bit better with php, but having issues.

I have a table that is populated by data pulled from a postgres database. Here is the code for that:

<?php
if ($numrows) {
		for ($b=0;$b<$numrows;$b++) {
			?>
			<tr>
      			<td width="29%"><?php echo($call[$b]) ?></td>
      			<td width="60%">
					<?php 
						$timerecord = date("m/d/Y H:i",$starttime[$b]);
						echo($timerecord); 
					?>

I am trying to make it that you can click on a link within each record to display the entire data for that row ($b). Im guessing I need to do an OnClick somehow with javascript and pass at least the value of $b to PHP to generate a report of that entire entry. (this is for a tech support call log) Could you show me how to take a link, and when clicked have it store a variable in php (a registered session variable) so it can be used on other pages. I have very limited resources at my disposal. God bless the net.

Thanks,
INTELImaxx

Everybody does sooner or later, or else a long time ago. For me, "just when I think I've got it ... it's gone...." <hmm....sing, etc.>

Well, you are aware that PHP can only work on the server side. This means that the browser has to send a request to the server and receive a reply, generally in the form of an HTML-type page (and I use the term loosely, 'cause PHP can output all kinds of stuff to browsers...).

In order to send the server a request, you must either POST an HTML form, or request a URL with a query string attached. These are known as the POST method and the GET method, respectively. If you must use javascript here, then your onClick() would either call a function that passes a request of the form http://somewhere.com?somevar=somevalue, or else does a form.submit().

There's really no need to use javascript ... why not just have an anchor tag that points to a handler script (or even to $PHP_SELF) if you wish to write the script that way) including the appropriate URL code for a GET request for that particular log entry?

There's more in the newbies forum FAQ that might help.

HTH,

I appologize for the ignorance, I made the switch from ASP about 3 weeks ago. I might just fix the problem by creating a form to do the work. Two clicks instead of one. I think they can deal with that. Much abliged on the reply. 😃

Hey, who's ignorant? You're doing fine, and asking good questions.

Just for curiosity's sake, how would you do it differently with ASP? Java applet?
