* Function logic:
|
|
* 1 .) Check, if the table exists
|
|
* 2a.) If not, create it with the field specification, exit
|
|
* 2b.) If the table exists, check, if the field exist
|
|
* 3 .) If not, try to find the field using previous names (if specified in $field like "name1,name2")
|
|
* 4a.) If the field hasn't been found, create the field as specified, exit
|
|
* 4b.) If the field has been found using a previous name (if specified) rename the column to $field
|
|
* 5 .) As the field has been found, check, if the field's type is matching
|
|
* 5a.) If the type is matching, exit
|
|
* 5b.) If the field's content type is not matching, try to convert first (e.g. string to int
|
|
* or int to string), then use the upgrade statement if applicable
|
|
*
|
|
* Note about the upgrade statement:
|
|
* - the code must be eval'able
|
|
* - the code needs to read $oldVal (old field value) and needs to set $newVal (value to which the field will be set)
|
|
* - $oldVal might be empty if the field didn't exist
|
|
* - $tableValues['fieldname'] contains the already existing values
