Constructor function

Returns:: void

t3lib_install::setValueInLocalconfFile	(	&$	line_array,
		$	variable,
		$	value
	)

This functions takes an array with lines from localconf.php, finds a variable and inserts the new value.

Parameters:

	array	$line_array the localconf.php file exploded into an array by linebreaks. (see writeToLocalconf_control())
	string	$variable The variable name to find and substitute. This string must match the first part of a trimmed line in the line-array. Matching is done backwards so the last appearing line will be substituted.
	string	$value Is the value to be insert for the variable

Returns:: void

	)

Writes or returns lines from localconf.php

Parameters:

	array	Array of lines to write back to localconf.php. Possibly
	string	Absolute path of alternative file to use (Notice: this path is not validated in terms of being inside 'TYPO3 space')

Returns:: mixed If $inlines is not an array it will return an array with the lines from localconf.php. Otherwise it will return a status string, either "continue" (updated) or "nochange" (not updated)

t3lib_install::getFieldDefinitions_sqlContent ( $ sqlContent )

Reads the field definitions for the input sql-file string

Parameters:

string

$sqlContent: Should be a string read from an sql-file made with 'mysqldump [database_name] -d'

Returns:: array Array with information about table.

t3lib_install::getFieldDefinitions_sqlContent_parseTypes ( &$ total )

Multiplies varchars/tinytext fields in size according to $this->multiplySize Useful if you want to use UTF-8 in the database and needs to extend the field sizes in the database so UTF-8 chars are not discarded. For most charsets available as single byte sets, multiplication with 2 should be enough. For chinese, use 3.

Parameters:

array

Total array (from getFieldDefinitions_sqlContent())

Returns:: void private

t3lib_install::getFieldDefinitions_database ( )

Reads the field definitions for the current database

Returns:: array Array with information about table.

t3lib_install::getDatabaseExtra	(	$	FDsrc,
		$	FDcomp,
		$	onlyTableList = `''`,
		$	ignoreNotNullWhenComparing = `true`
	)

Compares two arrays with field information and returns information about fields that are MISSING and fields that have CHANGED. FDsrc and FDcomp can be switched if you want the list of stuff to remove rather than update.

Parameters:

	array	Field definitions, source (from getFieldDefinitions_sqlContent())
	array	Field definitions, comparison. (from getFieldDefinitions_database())
	string	Table names (in list) which is the ONLY one observed.
	boolean	If set, this function ignores NOT NULL statements of the sql file field definition when comparing current field definition from database with field definition from sql file. This way, NOT NULL statements will be executed when the field is initially created, but the sql parser will never complain about missing NOT NULL statements afterwards.

Returns:: array Returns an array with 1) all elements from $FSsrc that is not in $FDcomp (in key 'extra') and 2) all elements from $FSsrc that is difference from the ones in $FDcomp

t3lib_install::getUpdateSuggestions	(	$	diffArr,
		$	keyList = `'extra`,
		diff'
	)

Returns an array with SQL-statements that is needed to update according to the diff-array

Parameters:

	array	Array with differences of current and needed DB settings. (from getDatabaseExtra())
	string	List of fields in diff array to take notice of.

Returns:: array Array of SQL statements (organized in keys depending on type)

t3lib_install::assembleFieldDefinition ( $ row )

Converts a result row with field information into the SQL field definition string

Parameters:

t3lib_install::getStatementArray	(	$	sqlcode,
		$	removeNonSQL = `0`,
		$	query_regex = `''`
	)

Returns an array where every entry is a single sql-statement. Input must be formatted like an ordinary MySQL-dump files

Parameters:

	string	$sqlcode The sql-file content. Provided that 1) every query in the input is ended with ';' and that a line in the file contains only one query or a part of a query.

	string	Regex to filter SQL lines to include.

Returns:: array Array of SQL statements.

Returns tables to create and how many records in each

Parameters:

	array	Array of SQL statements to analyse.
	boolean	If set, will count number of INSERT INTO statements following that table definition

Returns:: array Array with table definitions in index 0 and count in index 1

t3lib_install::getTableInsertStatements	(	$	statements,
		$	table
	)

Extracts all insert statements from $statement array where content is inserted into $table

Parameters:

	array	Array of SQL statements
	string	Table name

Returns:: array Array of INSERT INTO statements where table match $table

t3lib_install::performUpdateQueries	(	$	arr,
		$	keyArr
	)

Performs the queries passed from the input array.

Parameters:

	array	Array of SQL queries to execute.
	array	Array with keys that must match keys in $arr. Only where a key in this array is set and true will the query be executed (meant to be passed from a form checkbox)

Returns:: void

		$	currentValue = `array()`,
		$	cVfullMsg = `0`
	)

Creates a table which checkboxes for updating database.

Parameters:

	array	Array of statements (key / value pairs where key is used for the checkboxes)
	string	Label for the table.
	boolean	If set, then checkboxes are set by default.
