[justride]

hi all,

i am new to php charts but can i make a progress bar during a for loop, i want to show the user the % of progress for a script during an installation i am doing. like say im adding 5000 records to a db, show percantage of completion without refreshing the page.

thanks

Your script runs on the server, your client waits (may be) on the other side of our planet. Client browser window is not your script console. So without some kind of client side scripting you can't communicate on-line between PHP script and client browser.

without refreshing ?? why ? You must only make it look that it doesn't refresh but you need refreshing. second of all you must know on the serverside how long the job is going to take otherwise you can't tell the progress in waiting time.

you can do it easily with an single color image of widh 1 and height 20 then set te newwidth with

time elapsed/totaltime *100=newwidth of image

hey all, sorry to sound silly. i know php is server side and thats why i mentioned php with jscript embeded. I dont want the page refreshing.

heres the deal, i have a for loop calculating percentage each time around.

for i=0 i<5000 ....

I insert records into a table, how can i make a prgress bar

for( $i = 0; $i < $TOTAL_LINK_RECORDS; $i ++ ) { 
  		
		$percentage = $i / $TOTAL_LINK_RECORDS;
...... code....

echo "<script> incrCount(".substr($percentage,2,2).")  //set bar to 50% </script>";
	}

something like that.

this doesnt work just right

You can update data on a page without refreshing in the browser. This is the whole point of AJAX and online apps like

A couple years ago, I would probably do this with an iframe. I am still researching how this is done with AJAX and know little about it but think this may be the way you want to go.

laughs at me in Firefox and returns errors in MSIE.
