Updating multiple rows in mysql - travis barker dating rihanna

Example (User enters: 24052)If "Use Alternative" is checked, then use hidden constant [X] to calculate "Value Saved": (24052 - X = 1022) Well, even though I have shown my table structure, if you have a much more logical table structure for this survey, by all means I would love see what you had in mind.

Unfortunately, I had no knowledge of arrays (which are the keys to the solution) and ended up Google-searching for many hours. It isn’t elegant, as I am quite the amateur coder, but it works and contains all the basics that you’ll need.Most text fields can be displayed with something like htmlentities($fieldvalue, ENT_QUOTES).If your server does not have the “magic quotes” featured turned on, text fields should be processed with something like mysql_real_escape_string($fieldvalue).Hi Site Point members I have been perusing through the solutions for "updating multiple rows with one query", but I have a pressing question: How would one "SET" multiple column values with one query?Here is my example..normal update command would be: // question ID ranges from 1-20 // $questionid == 1, $member_id==1 UPDATE table_Foo Bar SET answer One='$ans1Val', answer Two='$ans2Val', answer Three='$ans3Val' WHERE member_id='$memberid' AND question_id='$questionid'; // $questionid == 2, $member_id==1 UPDATE table_Foo Bar SET answer One='$ans1Val', answer Two='$ans2Val', answer Three='$ans3Val' WHERE member_id='$memberid' AND question_id='$questionid'; ..you really ought to help make it easier for poeple to try to help you.

There are other issues but, I got confused with the table names.

For people who have basic knowledge in updating My SQL information through a PHP form, you’ll notice that almost all of the tutorials only tell you how to update ONE record at a time.

;) table_foobar ( foobar_id, member_id, question_id, answer One, answer Two, answer Three, answer Four ) //Multiple questions for a single foobar Main survey.

tbl_foobar Question ( question_id, foobar Main_id, foobar Question ) tbl_foobar Main ( foobar Main_id, foobar Name, foobar Description ) your database is not normalised as was mentioned before.

UPDATE table_Foo Bar SET answer One='yes', answer Two='no', answer Three='yes' WHERE member_id = 1 AND question_id = 1; UPDATE table_Foo Bar SET answer One='no', answer Two='no', answer Three='yes' WHERE member_id = 1 AND question_id = 2; UPDATE table_Foo Bar SET answer One='yes', answer Two='yes', answer Three='no' WHERE member_id = 1 AND question_id = 3; oh, absolutely!!
