cffile in cfscript quick cheat sheet
First time for using CFFILE within cfscript so thought I should document this for myself and anyone else.
Open and close a file
1myFile = expandPath( "somefile.txt" );
2fileObj = fileRead( myFile );
3writeOutput(fileObj);
4// OR
5myFile = expandPath( "somefile.txt" );
6fileObj = fileOpen( myFile, "read" );
7fileClose( fileObj ); // Once a file is closed you cannot access the object
2fileObj = fileRead( myFile );
3writeOutput(fileObj);
4// OR
5myFile = expandPath( "somefile.txt" );
6fileObj = fileOpen( myFile, "read" );
7fileClose( fileObj ); // Once a file is closed you cannot access the object
Write to a file
1myFile = expandPath( "somefile.txt" );
2data = "I'm going to create a file object";
3FileWrite( "fileObj", data );
4newFileObj = FileRead( "fileObj" );
5writeDump(var=newFileObj);
6// OR write direct to file
7myFile = expandPath( "somefile.txt" );
8data = "I'm going to write to direct to file";
9FileWrite(myFile, data);
2data = "I'm going to create a file object";
3FileWrite( "fileObj", data );
4newFileObj = FileRead( "fileObj" );
5writeDump(var=newFileObj);
6// OR write direct to file
7myFile = expandPath( "somefile.txt" );
8data = "I'm going to write to direct to file";
9FileWrite(myFile, data);
Append a line to a file
1myFile = expandPath( "somefile.txt" );
2fileObj = FileOpen( myFile, "append");
3fileWriteLine(fileObj,"This line is new.");
4fileClose(fileObj);
2fileObj = FileOpen( myFile, "append");
3fileWriteLine(fileObj,"This line is new.");
4fileClose(fileObj);
Output a text file to the screen
1myFile = expandPath( "somefile.txt" );
2fileObj = fileOpen( myFile, "read" );
3while( NOT fileIsEOF( fileObj ) ){
4line = fileReadLine( fileObj );
5WriteOutput( "#line# <br/>" );
6}
7FileClose( fileObj );
2fileObj = fileOpen( myFile, "read" );
3while( NOT fileIsEOF( fileObj ) ){
4line = fileReadLine( fileObj );
5WriteOutput( "#line# <br/>" );
6}
7FileClose( fileObj );
Copy/Move and delete a file
1myFile = expandPath( "somefile.txt" );
2myCopyFile = expandPath( "somefile2.txt" );
3fileCopy( myFile, myCopyFile); // fileMove() works the same
4writeOutput( fileExists( myCopyFile ) ); // Check copy worked
5fileDelete( myCopyFile );
6writeOutput( fileExists( myCopyFile ) ); // Check delete worked
2myCopyFile = expandPath( "somefile2.txt" );
3fileCopy( myFile, myCopyFile); // fileMove() works the same
4writeOutput( fileExists( myCopyFile ) ); // Check copy worked
5fileDelete( myCopyFile );
6writeOutput( fileExists( myCopyFile ) ); // Check delete worked
