X-Git-Url: http://git.mjollnir.org/gw?a=commitdiff_plain;h=7ba7461530dd35a90f5948124553aee3d7b76394;p=moodle.git Finished restoring course, course_sections and course_modules. When ending the restore process, we've to update the instance field of course_modules and the modinfo field of course. Now we haven´t the necessary info to do that. --- diff --git a/backup/lib.php b/backup/lib.php index 75a1900ce6..a9091557cc 100644 --- a/backup/lib.php +++ b/backup/lib.php @@ -302,4 +302,35 @@ } } } + + //This function is used to insert records in the backup_ids table + function backup_putid ($backup_unique_code, $table, $old_id, $new_id, $info="") { + + global $CFG; + + $status = true; + + //First delete to avoid PK duplicates + $status = backup_delid($backup_unique_code, $table, $old_id); + + $status = execute_sql("INSERT INTO {$CFG->prefix}backup_ids + (backup_code, table_name, old_id, new_id, info) + VALUES + ($backup_unique_code, '$table', '$old_id', '$new_id', '$info')",false); + return $status; + } + + //This function is used to delete recods from the backup_ids table + function backup_delid ($backup_unique_code, $table, $old_id) { + + global $CFG; + + $status = true; + + $status = execute_sql("DELETE FROM {$CFG->prefix}backup_ids + WHERE backup_code = $backup_unique_code AND + table_name = '$table' AND + old_id = '$old_id'",false); + return $status; + } ?> diff --git a/backup/restore.php b/backup/restore.php index dde24dd42c..6999d707e2 100644 --- a/backup/restore.php +++ b/backup/restore.php @@ -79,7 +79,7 @@ } else if ($launch == "check") { include_once("restore_check.html"); } else if ($launch == "execute") { - include_once("restore_check.html"); + include_once("restore_execute.html"); } print_simple_box_end(); diff --git a/backup/restorelib.php b/backup/restorelib.php index 554e1950fe..e5bae5dbe7 100644 --- a/backup/restorelib.php +++ b/backup/restorelib.php @@ -65,6 +65,16 @@ return $info; } + //This function read the xml file and store its data from the sections in a object + function restore_read_xml_sections ($xml_file) { + + //We call the main read_xml function, with todo = SECTIONS + $info = restore_read_xml ($xml_file,"SECTIONS",false); +print_object($info); + + return $info; + } + //This function prints the contents from the info parammeter passed function restore_print_info ($info) { @@ -178,6 +188,187 @@ } return $status; } + + //This function create a new course record. + //When finished, course_header contains the id of the new course + function restore_create_new_course($restore,&$course_header) { + + global $CFG; + + $status = true; + + $fullname = $course_header->course_fullname; + $shortname = $course_header->course_shortname; + $currentfullname = ""; + $currentshortname = ""; + $counter = 0; + //Iteratere while the name exists + do { + if ($counter) { + $suffixfull = get_string("copy")."
