I have a column called name in a table info
So I want to update that with it's current value, like this name + user_input. I tried with this code but not working

mysql_query("UPDATE info SET name = name + '$user_input' WHERE id='$user_id'");

But It returns 0 and update column to 0....

Any idea how to accomplish this task?

You should use CONCAT to concatenate string in MySQL (+ is for addition arithmetic operations which I guess can't properly work with names) :

UPDATE info SET name = CONCAT(name,'$user_input') WHERE id='$user_id'

My issue is that I have a PHP FORM that is submitting values through more than 55 input-text-fields, into a MySQL table.

Now, when I use UPDATE feature, suppose for e.g for 3 fields:

$sql="UPDATE pathology_test_rates SET bsugar_random='$bsugar_random', bsugar_fasting='$bsugar_fasting', bsugar_pp='$bsugar_pp'";

And then , if I want to update only 1 value, out of above 3, using PHP FORM, its making other 2 values empty. Whereas, I want other 2 values to remain un-disturbed.

How to do this ? Please help. M not using id in table.
