Best way to prepare variable(s) for UPDATE query? (mysql/php) - crunchers - May 5th, 2011
Go easy (still learning).
Just wondering what the best approach would be for dynamically updating a record in mysql using PHP without using a loop when defining the row data as an array (key=column name, value=value).
I'd like to prepare the key and value from the array as a string and run the query once instead of iterating through the array using a loop for each key/value.
e.g.
PHP Code:
$data = array('col1' => 'one',
'col2' => 'two',
'col3' => 'three'
);
$str = ????
$query = ("UPDATE table_name SET ".$str." WHERE some_column=some_value")
I can figure out how to do it using a foreach loop; and I can easily prepare a variable when inserting multiple records using php implode function. I just can't figure out what the best approach would be for updating the table in the same fashion.

Nevermind. I apply the loop to the array instead of the query; what a moron! Just goes to show, you can't legislate for stupidity.

:q
PHP Code:
$data = array('col1' => 'one',
'col2' => 'two',
'col3' => 'three'
);
foreach ($data as $field => $value) {
$list[] = $field.'='."'".mysql_real_escape_string($value)."'";
}
$fields = implode(', ', $list);
$query = "UPDATE table_name SET ".$fields." WHERE some_column=some_value";

This is one oldest design of England pounds. So, why you are still living in older times and not moving to further levels of
