Manual  /  Functions  /  Other functions  /  ResizeImage

Arguments:

Name	Description
$field	The name of the uploadfield where the image is uploaded
$saveAs	How the new image should be saved. When nothing is given, the original will be overwritten. If you want to save a copy of the original image, use something like this: "dir/to/save/" IF you want to save it with another filename, use something like this: "dir/to/save/image" The file wil now be saved as "image.<ext>", where <ext> is the extension of the file.
$maxWidth	The maximum width of the image. If none is given, the default is loaded which is set in the config file with the var FH_DEFAULT_RESIZE_WIDTH.
$maxHeight	The maximum height of the image. If none is given, this value will be the same as $maxWidth.
$quality	The quality used for the resized image. When no quality is given, 80% is used.
$constrainProportions	Keep the proportions when the image is resized?

Description:

NOTE: If only the MaxWidth is set, the MaxHeight will be set to the same value as MaxWidth!

NOTE: The uploadfield creates the dir if it does not exists. The ResizeImage function does NOT! So make sure that the dir exists where the resized image is put!

Example

<?php // include the class include('FH3/class.FormHandler.php'); // get the current dir working in $curDir = $_SERVER['DOCUMENT_ROOT'] . dirname( $_SERVER['PHP_SELF'] ); // upload config $config = array( 'path' => $curDir .'/uploads/', 'type' => 'jpg jpeg png gif', 'exists' => 'rename' ); // create new formhandler object $form = new FormHandler('myForm'); // uploadfield $form->uploadField('Image', 'image', $config); // save the resized image as... // MAKE SURE THAT THIS DIR EXISTS! $saveAs = $curDir .'/uploads/thumbs/'.$form->value('image'); // resize the image $form->resizeImage( 'image', $saveAs, 200 ); // submit button... $form->submitButton(); // commit after form function $form->onCorrect('doRun'); // flush the form $form->flush(); // the commit after form function function doRun($data) { global $curDir; $dir = $curDir .'/uploads/'; // display the images echo "<img src='". $dir . "thumbs/" . $data['image'] . "' border='0' />\n". "<img src='". $dir . $data['image'] ."' border='0' />\n"; } ?>
