[Resolved] php, javascript and select boxs

mikster

im dynamically changing an image based on the used input from a form, i want the entered data to stay on the form when the page refeshes to update the image.

For the text box i just created a variable in php and grabbed the value of the text box when the form was posted using $_post, then in the text tag i did value=<?php echo "variable" ?> and this worked fine.
i tried to do the same with selection boxes and it didnt work, i.e

this didnt work, so then i just tried manually setting the selection of the selection list i.e selectedIndex = 1, just to see if i was setting it the right way, this didnt work either

what am i doing wrong? how do i set/change the selected item from a select list?

cheers

dont double post!

your problem arises because there is no such thing as selectedIndex in html.

a selected item would look like.

<option value="foo" selected>foo

so, its a matter of setting up an if statement that will place the word 'selected' in the selected item.

yeah sorry about the double posting, i posted it in the newbie one but then thought it seemed a bit too complex to be a newbie post so i put it in the other one, im guessing ur not supposed to do that. Any ways i figured it out now, i used javascripts onload handler to do a select.selectedIndex = and then did a php echo to put the variable into it. so now every time the page is reloaded onload takes the saved values from php and and sets it to the selectIndex of the select box. thanks for reminding me that it was a javascript property, it all clicked after that.
