monk.e.boy Posted April 19, 2007 Share Posted April 19, 2007 what's wrong with the code you posted? If they are strings, you may need to cast them to ints using: $num = int_val('123'); monk.e.boy Link to comment https://forums.phpfreaks.com/topic/47709-adding-two-variables-and-assigning-to-a-hidden-field/#findComment-232990 Share on other sites More sharing options...
thechris Posted April 19, 2007 Author Share Posted April 19, 2007 it returns a 0 when its posted to the new table in the database no they aren't strings they started as integers Link to comment https://forums.phpfreaks.com/topic/47709-adding-two-variables-and-assigning-to-a-hidden-field/#findComment-232993 Share on other sites More sharing options...
thechris Posted April 19, 2007 Author Share Posted April 19, 2007 it works when it is not in the hidden field and displays the correct number but when it is in the hidden field the database just reads it as zero. I think that it is just not updating the table correctly because the forumla works when its out of the hidden field and i can put it in a variable and it'll print out the variable correctly but when I try to put the variable into the table it still reads as a zero. ???

monk.e.boy Posted April 19, 2007 Share Posted April 19, 2007 On the page with the hidden field on it, do a view source and check the hidden value is set to something. Why not pass player 1 ID and player 2 ID instead of all that crap. Then when the form is processed, look all these details up in the database. If not, liberal use of: print_r( $_POST ); is useful for debugging. If you are doing this for money, then invest in: http://www.nusphere.com/, it is the roxor monk.e.boy Link to comment https://forums.phpfreaks.com/topic/47709-adding-two-variables-and-assigning-to-a-hidden-field/#findComment-233043 Share on other sites More sharing options...
