Say the image is called:gecko.jpg
Can I first remove ".jpg" and add "-100x100" after "gecko", and then put the extension back, so it would be "gecko-100x100.jpg"?
use pathinfo
$path_parts = pathinfo('/www/htdocs/inc/lib.inc.php');
$new = $path_parts['filename'] . '-100x100.' .$path_parts['extension'];
Yes, quite simply with PHP's string functions in conjunction with basename()
$base = basename($filename, ".jpg");
echo $base . "-100x100" . ".jpg";
Or to do it with any filetype using strrpos() to locate the extension by finding the last .
// Use strrpos() & substr() to get the file extension
$ext = substr($filename, strrpos($filename, "."));
// Then stitch it together with the new string and file's basename
$newfilename = basename($filename, $ext) . "-100x100" . $ext;
--
// Some examples in action...
$filename = "somefile.jpg";
$ext = substr($filename, strrpos($filename, "."));
$newfilename = basename($filename, $ext) . "-100x100" . $ext;
echo $newfilename;
// outputs somefile-100x100.jpg
// Same thing with a .gif
$filename = "somefile.gif";
// outputs somefile-100x100.gif

I'm trying to copy an image using the path which is stored in my DB. I tried this but it throws "Array To String Conversion" error. I've never dealt with this before. Here's my code.
$record = AboutPageIntro::find($id);
$img_name = $record->image;
$ext = explode('.', $img_name);
Storage::disk('local')->copy(public_path($record->image), public_path('uploads/about_page/intro/' . uniqid() . '.' . $ext));
You're attempting to convert an array from explode('.', $img_name); to a string in the final line.
$record = AboutPageIntro::find($id);
$img_name = $record->image;
$ext = explode('.', $img_name); // This is an array like ['image_name', 'ext]
Storage::disk('local')->copy(
public_path($record->image),
public_path('uploads/about_page/intro/' . uniqid() . '.' . $ext[count($ext)-1])
); // You'll need to address the last item in the array by its index like this
That said, pathinfo(...) is the safer option here.
$record = AboutPageIntro::find($id);
$img_name = $record->image;
$ext = pathinfo($img_name, PATHINFO_EXTENSION);
Storage::disk('local')->copy(
public_path($record->image),
public_path('uploads/about_page/intro/' . uniqid() . '.' . $ext
);
I think its a simple problem of using explode as it will return an array of strings based on the dividing parameter.
I'm not too savvy with OOP but I can suggest using str_replace or trim to remove the '.'s in the $img_name variable.
$record = AboutPageIntro::find($id);
$img_name = $record->image;
$ext = str_replace('.',"",$img_name);
Storage::disk('local')->copy(public_path($record->image), public_path('uploads/about_page/intro/' . uniqid() . '.' . $ext));
I created a page that can upload file to my database, but when a filename has (.), it doesnt save properly. For example I upload a file named imagefile.50.jpg, it just saves as image20.50
<?php
function upload_image()
{
if(isset($_FILES["user_image"]))
{
$extension = explode('.', $_FILES['user_image']['name']);
$new_name = $extension[0] . '.' . $extension[1];
$destination = './upload/' . $new_name;
move_uploaded_file($_FILES['user_image']['tmp_name'], $destination);
return $new_name;
}
}
To get the filename and extension of a file, you can use pathinfo, i.e.:
$file = "some_dir/somefile.test.php"; # $_FILES['user_image']['name']
$path_parts = pathinfo($file);
$fn = $path_parts['filename'];
$ext = $path_parts['extension'];
print $fn."\n";
print $ext;
Output:
somefile.test

How can I change name of uploaded file in Laravel 4.
So far I have been doing it like this:
$file = Input::file('file');
$destinationPath = 'public/downloads/';
if (!file_exists($destinationPath)) {
mkdir("./".$destinationPath, 0777, true);
}
$filename = $file->getClientOriginalName();
But if I have 2 files with the same name I guess it gets rewritten, so I would like to have something like (2) added at the end of the second file name or to change the file name completely
The first step is to check if the file exists. If it doesn't, extract the filename and extension with pathinfo() and then rename it with the following code:
$img_name = strtolower(pathinfo($image_name, PATHINFO_FILENAME));
$img_ext = strtolower(pathinfo($image_name, PATHINFO_EXTENSION));
$filecounter = 1;
while (file_exists($destinationPath)) {
$img_duplicate = $img_name . '_' . ++$filecounter . '.'. $img_ext;
$destinationPath = $destinationPath . $img_duplicate;
}
The loop will continue renaming files as file_1, file_2 etc. as long as the condition file_exists($destinationPath) returns true.
I know this question is closed, but this is a way to check if a filename is already taken, so the original file is not overwriten:
(... in the controller: ... )
$path = public_path().'\\uploads\\';
$extension = pathinfo($fileName, PATHINFO_EXTENSION);
$original_filename = pathinfo($fileName, PATHINFO_FILENAME);
$new_filename = $this->getNewFileName($original_filename, $extension, $path);
$upload_success = Input::file('file')->move($path, $new_filename);
this function get an "unused" filename:
public function getNewFileName($filename, $extension, $path){
$i = 1;
$new_filename = $filename.'.'.$extension;
while( File::exists($path.$new_filename) )
$new_filename = $filename.' ('.$i++.').'.$extension;
return $new_filename;
}
I'm trying to rename the input file to be a .jpg after conversion, but for some reason I'm getting a file.png.jpg when I'm really looking for file.jpg
Here is my code:
$source = $path . $_POST['username']. "-" . $_FILES['t1']['name'];
$destination = $path . $_POST['username']. "-" . basename($_FILES['t1']['name']) . ".jpg";
Use pathinfo():
$source = $path . $_POST['username']. "-" . $_FILES['t1']['name'];
$path_parts = pathinfo( $_FILES['t1']['name'] );
$destination = $path . $_POST['username']. "-" . $path_parts['filename'] . ".jpg";
Let's say that the variable $filename contains your image name with the png extension.
In order to change the extension to jpg , simply run it through this function :
function replace_extension($filename) {
return preg_replace('/\..+$/', '.' . '.jpg', $filename);
}
The basename() function includes the original files extension
Use the pathinfo() function to return an array of informatino about the file and use the filename with out the extension
Replace
$destination = $path . $_POST['username']. "-" . basename($_FILES['t1']['name']) . ".jpg";
with
$info = pathinfo($_FILES['t1']['name']);
$destination = $path . $_POST['username']. "-" . $info['filename'] . ".jpg";
You can either use the second parameter to basename to kill the suffix
$filename = basename($_FILES['t1']['name'], ".png");
or you could do some string manipulation
$filename = substr($_FILES['t1']['name],0, strrpos($_FILES['t1']['name'], ".") -1);
basename returns you the whole filename, including the file type suffix (i.e. ".jpg"). If you want to strip the suffix, you can call the function with a second parameter: basename($_FILES['t1']['name'], 'png').
But if you want to convert a png to a jpg, you can't just change the filename, you have to convert the file using special functions, see "Use PHP to convert PNG to JPG with compression?".
I have this snippet from my uploadify.php:
if (!empty($_FILES)) {
$name = $_FILES['Filedata']['name'];
$tempFile = $_FILES['Filedata']['tmp_name'];
$targetPath = $targetFolder;
$targetFile = rtrim($targetPath,'/') . '/' . $_FILES['Filedata']['name'];
$path = pathinfo($targetFile);
// this portion here will be true if and only if the file name of the uploaded file does not contain '.', except of course the dot(.) before the file extension
$count = 1;
list( $filename, $ext) = explode( '.', $name, );
$newTargetFile = $targetFolder . $filename . '.' . $ext;
while( file_exists( $newTargetFile)) {
$newTargetFile = $targetFolder . $filename . '(' . ++$count . ')' . '.' . $ext;
}
// Validate the file type
$fileTypes = array('pdf'); // File extensions
$fileParts = pathinfo($_FILES['Filedata']['name']);
if (in_array($fileParts['extension'],$fileTypes)) {
move_uploaded_file($tempFile,$newTargetFile);
echo $newTargetFile;
} else {
echo 'Invalid file type.';
}
return $newTargetFile;
}
Basically this is quite working. Uploading the file and getting the path of the file which will then be inserted on the database and so on. But, I tried uploading a file which file name looks like this,
filename.1.5.3.pdf
and when succesfully uploaded, the file name then became filename alone, without having the file extension and not to mention the file name is not complete. From what I understood, the problem lies on my explode(). It exploded the string having the delimiter '.' and then assigns it to the variables. What will I do to make the explode() cut the string into two where the first half is the filename and the second is the file extension? PLease help.
Don't use explode, use a function designed for the job: pathinfo()
$ext = pathinfo($_FILES['Filedata']['name'], PATHINFO_EXTENSION);
