Problem passing a var in a url and getting it back in the next pgm.

[Phrank]

I load up a url with a variable called category at the end.

function GoPrev() {
location="categories.php?Process=Prev&category=" + document.categories.category.value

The category is Food & Cooking

When I get to the next program it has %20's instead of spaces.

?Process=Prev&category=Food%20&%20Cooking

Now I want to put it back to normal in the pgm I get to. I have tried str_replace.

echo "<br> org category =" . str_replace("%20"," ",$category);

and several other functions but all I get is Food and not Food & Cooking.

Is there a function to fix the var received from a url?

Newby I know. TIA

The ampersand in between the two %20's is giving you a problem. In a URL query string the ampersand is used to seperate out name=value pairs.

In your script $category is only actually equal to Food. The ampersand then appears and the query string will be expecting a new name=value pair.

document.categories.category.value
You need to use Javascript's escape() function on this.

str_replace("%20"," ",$category)
You don't need this.
