passing variable on run time

yahelb

i have 2 pages:
1. main page with html and js data AND the picture.
2. picture that created dynamically.

the picture create an array with x and y values for image map.

i need to use the array in page 1 that should contain the map.

i already tried to use sessions .

is there a way at all to do that?

If I understand your question correctly you might want to try making a button on page one that will link to page two. this way you can post the data over to the next page via hidden form. HTH!

no you didnt understand me.

i have a html page

page 1:
created dynamically from php code.
<html>
<head>
<title></title>
</head>
<body>
<table>
<img src="my_picture_that_created_with_gd.png" USEMAP="my_map">
</table>

   <table>
   </table>

   <MAP NAME="mymap">
         <AREA SHAPE="rect" COORDS="0,0,100,24" ALT="la" HREF="lala">
   </MAP>

</body>
</html>

page 2:
file name: my_picture_that_created_with_gd.png
this file creates am image!
this file also creates and array with x and y values that i want to
use in page 1 map.

so the question is how do i pass the array or any ather variable from page 2 to page 1.

hi,

Hm.. I do not think you can.. The image which is created dynamically (img src="createimage.php?dataset=6" I assume) has it's own headertype, and I do not think you can send other info with that.

Is there no way to split the two of them? (I mean; creating the image, and generating the corrds' later?) You can always get the filesize etc and calculte the image map from that??

leatherback:

thanks for replaying this is good suggetion.

the thing is the picture is informative picture with rects on it.
it change and when i create page 1 i dont know what will be the
data and offcource not the x,y values.

i thout that i could write the data from file 2 (image) into a file,
on the server and read from file 1, but i think the problem there
will be that file 1 start to read before file 2 (image) end to write.

so i thought maybe someone here have an intresting idea for me.

Hi,

I understand that the image changes. But when you call the image, it is know from which data it is to be generated, otherwise you cannot generate the image, right?

So at that moment you should be able to say, include a script which first generates the image, but only retains the image-map coordinates. Then the second part it calls itself with the same set of data, but with an extra variable, which makes the age switch to the generate image section:

include("showimage.php");

showimage.php:

if($page ="")
  {
 // produce image, return imageinfo
  echo "<MAP NAME=\"mymap\"> 
<AREA SHAPE=\"rect\" COORDS=\"$mycords\" ALT=\"la\" HREF=\"lala\"> 
</MAP> 
"
  echo "<img src=\"showimage.php?data=$data&page=show\">";
  }
  else
   {
    //produce image, and spit out imagestream
   }
