PHP - AREA tags - replace shape coords with strings

[tommydog]

i am trying to generate an image map from the mouse coords of a click.
i can pass the X Y through ok as
$_POST['submit_x']
$_POST['submit_y']
how should the string be put into the AREA tag ?
i am keeping the diameter as 10

this is what i am trying:
echo "SHAPE=CIRC LE COORDS="'.$_POS T['submit_x'].',143,10">";

ok i worked it out !

COORDS={$_POST['submit_x']},{$_POST['submit_y']},10\">";

im pretty sure this will only work in IE and when you click on a submit button that uses an image.

let me know if im wrong, best of luck to you

when do i write my data to the data base?

i am building a browser based image map generator using php. each time an image is clicked the coords and a text box contents are to be saved somehow. i am expecting upto 50 lines of data for each image (x coord, y coord and text) :

sample data:
image name x y description
image7.jpg 123 123 wheel
image7.jpg 485 688 tyre
image7.jpg 456 595 bolt

later on i will display the image and create the hotspots image map with the text data (description) as html alt tags.

i have a data table in MYSQL with 4 columns:
1 image name
2 x_coord
3 y_coord
4 text for alt tags

do i collect 50 sets of data in a temp file or array or something and then write it to the database in one go or write each line of data as it is created ? my worry is that if i write to the database it may be a pain to edit any mistakes. so maybe some kind of preview table might be a good idea....
