Zane Posted July 1, 2013 Share Posted July 1, 2013 It should just be $row['prod_price'], tablenames are not needed when accessing the result of fetch_array() Link to comment https://forums.phpfreaks.com/topic/279728-how-to-select-from-2-tables-and-display-data/#findComment-1438758 Share on other sites More sharing options...

hance2105 Posted July 1, 2013 Author Share Posted July 1, 2013 the first product name in my table is missing and only the first price is being displayed in the text field Link to comment https://forums.phpfreaks.com/topic/279728-how-to-select-from-2-tables-and-display-data/#findComment-1438791 Share on other sites More sharing options...
jcbones Posted July 2, 2013 Share Posted July 2, 2013 Remove this line: $row=mysql_fetch_array($query); There is no call to that line, and all it is doing is moving the internal pointer to the second row. So subsequent calls to mysql_fetch_array() will continue from the second row. Thereby making you think that the first row has been skipped.

Barand Posted July 2, 2013 Share Posted July 2, 2013 Is it because you are using $row1 in the loop? Link to comment https://forums.phpfreaks.com/topic/279728-how-to-select-from-2-tables-and-display-data/#findComment-1439013 Share on other sites More sharing options...

hance2105 Posted July 2, 2013 Author Share Posted July 2, 2013 I tried everything so far but still this is a pain. I looked at the code over and over again but still can't know why the error message is being displayed and the price is not being populated. If it gets populated, i can proceed with price updates of the product being selected.

Barand Posted July 2, 2013 Share Posted July 2, 2013 It doesn't matter if you use $row, $row1 or $slartybartfast. Just be consistent. You can't use use $row for some fields and $row1 for others in the same while loop.

hance2105 Posted July 3, 2013 Author Share Posted July 3, 2013 Yes i know that. I did the necessary changes and used $row1 for the prod_price.
