Blog::save
Up: class Blog
This method updates the record contents in the database server. If previously detected errors have been accumulated in $this‑>msg this method suppresses the update, generates a warning that includes the text of the messages to explain why the record was not updated, and returns 0. If $blog‑>isExisting() is false this inserts a new record into the table. If $blog->isExisting() is true the existing database record is updated. This method extends the base implementation by setting the field 'bl_datetime' to the current date.
| parameter | description |
|---|---|
| $xml | If the value is boolean true then a representation of the SQL command issued to update the database is printed on the output enclosed in an XML <cmd> tag. If the value is a string then the representation of the SQL command issued to update the database is printed on the output enclosed in an XML <$xml> tag. If the leading characters of the string contain spaces these are extracted and used as an indentation value before the tag and end-tag. If there are any characters after a valid XML tag name these are extracted and presented only in the opening tag. Otherwise no output is generated. |
For example if the text is to be displayed as part of a web page then you may set the parameter to 'p' or " p class='cssclassname'".
The method returns boolean false if the method was unable to update the database, 1 if the method updated the database record, or 0 if the database did not need to be updated because there were no changes to the record.
The method throws an Exception if user is not authorized to update the database.
